+Writing Documentation:
+
+ Every user-visible change should be reflected in the documentation.
+ The same general rule as for code applies -- imitate the existing
+ conventions. A few commented examples follow to provide reference
+ when writing or modifying command usage strings and synopsis sections
+ in the manual pages:
+
+ Placeholders are spelled in lowercase and enclosed in angle brackets:
+ <file>
+ --sort=<key>
+ --abbrev[=<n>]
+
+ Possibility of multiple occurrences is indicated by three dots:
+ <file>...
+ (One or more of <file>.)
+
+ Optional parts are enclosed in square brackets:
+ [<extra>]
+ (Zero or one <extra>.)
+
+ --exec-path[=<path>]
+ (Option with an optional argument. Note that the "=" is inside the
+ brackets.)
+
+ [<patch>...]
+ (Zero or more of <patch>. Note that the dots are inside, not
+ outside the brackets.)
+
+ Multiple alternatives are indicated with vertical bar:
+ [-q | --quiet]
+ [--utf8 | --no-utf8]
+
+ Parentheses are used for grouping:
+ [(<rev>|<range>)...]
+ (Any number of either <rev> or <range>. Parens are needed to make
+ it clear that "..." pertains to both <rev> and <range>.)
+
+ [(-p <parent>)...]
+ (Any number of option -p, each with one <parent> argument.)
+
+ git remote set-head <name> (-a | -d | <branch>)
+ (One and only one of "-a", "-d" or "<branch>" _must_ (no square
+ brackets) be provided.)
+
+ And a somewhat more contrived example:
+ --diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]
+ Here "=" is outside the brackets, because "--diff-filter=" is a
+ valid usage. "*" has its own pair of brackets, because it can
+ (optionally) be specified only when one or more of the letters is
+ also provided.

-GIT v1.5.6.3 Release Notes
-==========================
-
-Fixes since v1.5.6.2
---------------------
-
-* Setting core.sharerepository to traditional "true" value was supposed to make
- the repository group writable but should not affect permission for others.
- However, since 1.5.6, it was broken to drop permission for others when umask is
- 022, making the repository unreadable by others.
-
-* Setting GIT_TRACE will report spawning of external process via run_command().
-
-* Using an object with very deep delta chain pinned memory needed for extracting
- intermediate base objects unnecessarily long, leading to excess memory usage.
-
-* Bash completion script did not notice '--' marker on the command
- line and tried the relatively slow "ref completion" even when
- completing arguments after one.
-
-* Registering a non-empty blob racily and then truncating the working
- tree file for it confused "racy-git avoidance" logic into thinking
- that the path is now unchanged.
-
-* The section that describes attributes related to git-archive were placed
- in a wrong place in the gitattributes(5) manual page.
-
-* "git am" was not helpful to the users when it detected that the committer
- information is not set up properly yet.
-
-* "git clone" had a leftover debugging fprintf().
-
-* "git clone -q" was not quiet enough as it used to and gave object count
- and progress reports.
-
-* "git clone" marked downloaded packfile with .keep; this could be a
- good thing if the remote side is well packed but otherwise not,
- especially for a project that is not really big.
-
-* "git daemon" used to call syslog() from a signal handler, which
- could raise signals of its own but generally is not reentrant. This
- was fixed by restructuring the code to report syslog() after the handler
- returns.
-
-* When "git push" tries to remove a remote ref, and corresponding
- tracking ref is missing, we used to report error (i.e. failure to
- remove something that does not exist).
-
-* "git mailinfo" (hence "git am") did not handle commit log messages in a
- MIME multipart mail correctly.
-
-Contains other various documentation fixes.

-GIT v1.6.0.2 Release Notes
-==========================
-
-Fixes since v1.6.0.1
---------------------
-
-* Installation on platforms that needs .exe suffix to git-* programs were
- broken in 1.6.0.1.
-
-* Installation on filesystems without symbolic links support did not
- work well.
-
-* In-tree documentations and test scripts now use "git foo" form to set a
- better example, instead of the "git-foo" form (which is an acceptable
- form if you have "PATH=$(git --exec-path):$PATH" in your script)
-
-* Many commands did not use the correct working tree location when used
- with GIT_WORK_TREE environment settings.
-
-* Some systems needs to use compatibility fnmach and regex libraries
- independent from each other; the compat/ area has been reorganized to
- allow this.
-
-
-* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
- a new line before the second line.
-
-* "git blame -c" did not exactly work like "git annotate" when range
- boundaries are involved.
-
-* "git checkout file" when file is still unmerged checked out contents from
- a random high order stage, which was confusing.
-
-* "git clone $there $here/" with extra trailing slashes after explicit
- local directory name $here did not work as expected.
-
-* "git diff" on tracked contents with CRLF line endings did not drive "less"
- intelligently when showing added or removed lines.
-
-* "git diff --dirstat -M" did not add changes in subdirectories up
- correctly for renamed paths.
-
-* "git diff --cumulative" did not imply "--dirstat".
-
-* "git for-each-ref refs/heads/" did not work as expected.
-
-* "git gui" allowed users to feed patch without any context to be applied.
-
-* "git gui" botched parsing "diff" output when a line that begins with two
- dashes and a space gets removed or a line that begins with two pluses
- and a space gets added.
-
-* "git gui" translation updates and i18n fixes.
-
-* "git index-pack" is more careful against disk corruption while completing
- a thin pack.
-
-* "git log -i --grep=pattern" did not ignore case; neither "git log -E
- --grep=pattern" triggered extended regexp.
-
-* "git log --pretty="%ad" --date=short" did not use short format when
- showing the timestamp.
-
-* "git log --author=author" match incorrectly matched with the
- timestamp part of "author " line in commit objects.
-
-* "git log -F --author=author" did not work at all.
-
-* Build procedure for "git shell" that used stub versions of some
- functions and globals was not understood by linkers on some platforms.
-
-* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
- and refused to work until the user refreshed the index.
-
-* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
- use of temporary files.
-
-* "git verify-pack -v" did not work correctly when given more than one
- packfile.
-
-Also contains many documentation updates.

-GIT v1.6.4.3 Release Notes
-==========================
-
-Fixes since v1.6.4.2
---------------------
-
-* "git clone" from an empty repository gave unnecessary error message,
- even though it did everything else correctly.
-
-* "git cvsserver" invoked git commands via "git-foo" style, which has long
- been deprecated.
-
-* "git fetch" and "git clone" had an extra sanity check to verify the
- presense of the corresponding *.pack file before downloading *.idx
- file by issuing a HEAD request. Github server however sometimes
- gave 500 (Internal server error) response to HEAD even if a GET
- request for *.pack file to the same URL would have succeeded, and broke
- clone over HTTP from some of their repositories. As a workaround, this
- verification has been removed (as it is not absolutely necessary).
-
-* "git grep" did not like relative pathname to refer outside the current
- directory when run from a subdirectory.
-
-* an error message from "git push" was formatted in a very ugly way.
-
-* "git svn" did not quote the subversion user name correctly when
- running its author-prog helper program.
-
-Other minor documentation updates are included.

-Git v1.6.5.4 Release Notes
-==========================
-
-Fixes since v1.6.5.3
---------------------
-
- * "git help" (without argument) used to check if you are in a directory
- under git control. There was no breakage in behaviour per-se, but this
- was unnecessary.
-
- * "git prune-packed" gave progress output even when its standard error is
- not connected to a terminal; this caused cron jobs that run it to
- produce crufts.
-
- * "git pack-objects --all-progress" is an option to ask progress output
- from write-object phase _if_ progress output were to be produced, and
- shouldn't have forced the progress output.
-
- * "git apply -p<n> --directory=<elsewhere>" did not work well for a
- non-default value of n.
-
- * "git merge foo HEAD" was misparsed as an old-style invocation of the
- command and produced a confusing error message. As it does not specify
- any other branch to merge, it shouldn't be mistaken as such. We will
- remove the old style "git merge <message> HEAD <commit>..." syntax in
- future versions, but not in this release,
-
- * "git merge -m <message> <branch>..." added the standard merge message
- on its own after user-supplied message, which should have overrided the
- standard one.
-
-Other minor documentation updates are included.

-
-* If a user specifies a color for a <slot> (i.e. a class of things to show
- in a particular color) that is known only by newer versions of git
- (e.g. "color.diff.func" was recently added for upcoming 1.6.6 release),
- an older version of git should just ignore them. Instead we diagnosed
- it as an error.
-
-* With help.autocorrect set to non-zero value, the logic to guess typoes
- in the subcommand name misfired and ran a random nonsense command.
-
-* If a command is run with an absolute path as a pathspec inside a bare
- repository, e.g. "rev-list HEAD -- /home", the code tried to run
- strlen() on NULL, which is the result of get_git_work_tree(), and
- segfaulted.

-Git v1.6.6 Release Notes
-========================
-
-Notes on behaviour change
--------------------------
-
- * In this release, "git fsck" defaults to "git fsck --full" and
- checks packfiles, and because of this it will take much longer to
- complete than before. If you prefer a quicker check only on loose
- objects (the old default), you can say "git fsck --no-full". This
- has been supported by 1.5.4 and newer versions of git, so it is
- safe to write it in your script even if you use slightly older git
- on some of your machines.
-
-Preparing yourselves for compatibility issues in 1.7.0
-------------------------------------------------------
-
-In git 1.7.0, which is planned to be the release after 1.6.6, there will
-be a handful of behaviour changes that will break backward compatibility.
-
-These changes were discussed long time ago and existing behaviours have
-been identified as more problematic to the userbase than keeping them for
-the sake of backward compatibility.
-
-When necessary, a transition strategy for existing users has been designed
-not to force them running around setting configuration variables and
-updating their scripts in order to either keep the traditional behaviour
-or adjust to the new behaviour, on the day their sysadmin decides to install
-the new version of git. When we switched from "git-foo" to "git foo" in
-1.6.0, even though the change had been advertised and the transition
-guide had been provided for a very long time, the users procrastinated
-during the entire transtion period, and ended up panicking on the day
-their sysadmins updated their git installation. We are trying to avoid
-repeating that unpleasantness in the 1.7.0 release.
-
-For changes decided to be in 1.7.0, commands that will be affected
-have been much louder to strongly discourage such procrastination, and
-they continue to be in this release. If you have been using recent
-versions of git, you would have seen warnings issued when you used
-features whose behaviour will change, with a clear instruction on how
-to keep the existing behaviour if you want to. You hopefully are
-already well prepared.
-
-Of course, we have also been giving "this and that will change in
-1.7.0; prepare yourselves" warnings in the release notes and
-announcement messages for the past few releases. Let's see how well
-users will fare this time.
-
- * "git push" into a branch that is currently checked out (i.e. pointed by
- HEAD in a repository that is not bare) will be refused by default.
-
- Similarly, "git push $there :$killed" to delete the branch $killed
- in a remote repository $there, when $killed branch is the current
- branch pointed at by its HEAD, will be refused by default.
-
- Setting the configuration variables receive.denyCurrentBranch and
- receive.denyDeleteCurrent to 'ignore' in the receiving repository
- can be used to override these safety features. Versions of git
- since 1.6.2 have issued a loud warning when you tried to do these
- operations without setting the configuration, so repositories of
- people who still need to be able to perform such a push should
- already have been future proofed.
-
- Please refer to:
-
- http://git.or.cz/gitwiki/GitFaq#non-bare
- http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
-
- for more details on the reason why this change is needed and the
- transition process that already took place so far.
-
- * "git send-email" will not make deep threads by default when sending a
- patch series with more than two messages. All messages will be sent
- as a reply to the first message, i.e. cover letter. Git 1.6.6 (this
- release) will issue a warning about the upcoming default change, when
- it uses the traditional "deep threading" behaviour as the built-in
- default. To squelch the warning but still use the "deep threading"
- behaviour, give --chain-reply-to option or set sendemail.chainreplyto
- to true.
-
- It has been possible to configure send-email to send "shallow thread"
- by setting sendemail.chainreplyto configuration variable to false.
- The only thing 1.7.0 release will do is to change the default when
- you haven't configured that variable.
-
- * "git status" will not be "git commit --dry-run". This change does not
- affect you if you run the command without pathspec.
-
- Nobody sane found the current behaviour of "git status Makefile" useful
- nor meaningful, and it confused users. "git commit --dry-run" has been
- provided as a way to get the current behaviour of this command since
- 1.6.5.
-
- * "git diff" traditionally treated various "ignore whitespace" options
- only as a way to filter the patch output. "git diff --exit-code -b"
- exited with non-zero status even if all changes were about changing the
- ammount of whitespace and nothing else. and "git diff -b" showed the
- "diff --git" header line for such a change without patch text.
-
- In 1.7.0, the "ignore whitespaces" will affect the semantics of the
- diff operation itself. A change that does not affect anything but
- whitespaces will be reported with zero exit status when run with
- --exit-code, and there will not be "diff --git" header for such a
- change.
-
-
-Updates since v1.6.5
---------------------
-
-(subsystems)
-
- * various gitk updates including use of themed widgets under Tk 8.5,
- Japanese translation, a fix to a bug when running "gui blame" from
- a subdirectory, etc.
-
- * various git-gui updates including new translations, wm states fixes,
- Tk bug workaround after quitting, improved heuristics to trigger gc,
- etc.
-
- * various git-svn updates.
-
- * "git fetch" over http learned a new mode that is different from the
- traditional "dumb commit walker".
-
-(portability)
-
- * imap-send can be built on mingw port.
-
-(performance)
-
- * "git diff -B" has smaller memory footprint.
-
-(usability, bells and whistles)
-
- * The object replace mechanism can be bypassed with --no-replace-objects
- global option given to the "git" program.
-
- * In configuration files, a few variables that name paths can begin with ~/
- and ~username/ and they are expanded as expected.
-
- * "git subcmd -h" now shows short usage help for many more subcommands.
-
- * "git bisect reset" can reset to an arbitrary commit.
-
- * "git checkout frotz" when there is no local branch "frotz" but there
- is only one remote tracking branch "frotz" is taken as a request to
- start the named branch at the corresponding remote tracking branch.
-
- * "git commit -c/-C/--amend" can be told with a new "--reset-author" option
- to ignore authorship information in the commit it is taking the message
- from.
-
- * "git describe" can be told to add "-dirty" suffix with "--dirty" option.
-
- * "git diff" learned --submodule option to show a list of one-line logs
- instead of differences between the commit object names.
-
- * "git diff" learned to honor diff.color.func configuration to paint
- function name hint printed on the hunk header "@@ -j,k +l,m @@" line
- in the specified color.
-
- * "git fetch" learned --all and --multiple options, to run fetch from
- many repositories, and --prune option to remove remote tracking
- branches that went stale. These make "git remote update" and "git
- remote prune" less necessary (there is no plan to remove "remote
- update" nor "remote prune", though).
-
- * "git fsck" by default checks the packfiles (i.e. "--full" is the
- default); you can turn it off with "git fsck --no-full".
-
- * "git grep" can use -F (fixed strings) and -i (ignore case) together.
-
- * import-tars contributed fast-import frontend learned more types of
- compressed tarballs.
-
- * "git instaweb" knows how to talk with mod_cgid to apache2.
-
- * "git log --decorate" shows the location of HEAD as well.
-
- * "git log" and "git rev-list" learned to take revs and pathspecs from
- the standard input with the new "--stdin" option.
-
- * "--pretty=format" option to "log" family of commands learned:
-
- . to wrap text with the "%w()" specifier.
- . to show reflog information with "%g[sdD]" specifier.
-
- * "git notes" command to annotate existing commits.
-
- * "git merge" (and "git pull") learned --ff-only option to make it fail
- if the merge does not result in a fast-forward.
-
- * "git mergetool" learned to use p4merge.
-
- * "git rebase -i" learned "reword" that acts like "edit" but immediately
- starts an editor to tweak the log message without returning control to
- the shell, which is done by "edit" to give an opportunity to tweak the
- contents.
-
- * "git send-email" can be told with "--envelope-sender=auto" to use the
- same address as "From:" address as the envelope sender address.
-
- * "git send-email" will issue a warning when it defaults to the
- --chain-reply-to behaviour without being told by the user and
- instructs to prepare for the change of the default in 1.7.0 release.
-
- * In "git submodule add <repository> <path>", <path> is now optional and
- inferred from <repository> the same way "git clone <repository>" does.
-
- * "git svn" learned to read SVN 1.5+ and SVK merge tickets.
-
- * "git svn" learned to recreate empty directories tracked only by SVN.
-
- * "gitweb" can optionally render its "blame" output incrementally (this
- requires JavaScript on the client side).
-
- * Author names shown in gitweb output are links to search commits by the
- author.
-
-Fixes since v1.6.5
-------------------
-
-All of the fixes in v1.6.5.X maintenance series are included in this
-release, unless otherwise noted.

+GIT v1.5.6.3 Release Notes
+==========================
+
+Fixes since v1.5.6.2
+--------------------
+
+* Setting core.sharedrepository to traditional "true" value was supposed to make
+ the repository group writable but should not affect permission for others.
+ However, since 1.5.6, it was broken to drop permission for others when umask is
+ 022, making the repository unreadable by others.
+
+* Setting GIT_TRACE will report spawning of external process via run_command().
+
+* Using an object with very deep delta chain pinned memory needed for extracting
+ intermediate base objects unnecessarily long, leading to excess memory usage.
+
+* Bash completion script did not notice '--' marker on the command
+ line and tried the relatively slow "ref completion" even when
+ completing arguments after one.
+
+* Registering a non-empty blob racily and then truncating the working
+ tree file for it confused "racy-git avoidance" logic into thinking
+ that the path is now unchanged.
+
+* The section that describes attributes related to git-archive were placed
+ in a wrong place in the gitattributes(5) manual page.
+
+* "git am" was not helpful to the users when it detected that the committer
+ information is not set up properly yet.
+
+* "git clone" had a leftover debugging fprintf().
+
+* "git clone -q" was not quiet enough as it used to and gave object count
+ and progress reports.
+
+* "git clone" marked downloaded packfile with .keep; this could be a
+ good thing if the remote side is well packed but otherwise not,
+ especially for a project that is not really big.
+
+* "git daemon" used to call syslog() from a signal handler, which
+ could raise signals of its own but generally is not reentrant. This
+ was fixed by restructuring the code to report syslog() after the handler
+ returns.
+
+* When "git push" tries to remove a remote ref, and corresponding
+ tracking ref is missing, we used to report error (i.e. failure to
+ remove something that does not exist).
+
+* "git mailinfo" (hence "git am") did not handle commit log messages in a
+ MIME multipart mail correctly.
+
+Contains other various documentation fixes.

+GIT v1.6.0.2 Release Notes
+==========================
+
+Fixes since v1.6.0.1
+--------------------
+
+* Installation on platforms that needs .exe suffix to git-* programs were
+ broken in 1.6.0.1.
+
+* Installation on filesystems without symbolic links support did not
+ work well.
+
+* In-tree documentations and test scripts now use "git foo" form to set a
+ better example, instead of the "git-foo" form (which is an acceptable
+ form if you have "PATH=$(git --exec-path):$PATH" in your script)
+
+* Many commands did not use the correct working tree location when used
+ with GIT_WORK_TREE environment settings.
+
+* Some systems need to use compatibility fnmatch and regex libraries
+ independent from each other; the compat/ area has been reorganized to
+ allow this.
+
+
+* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
+ a new line before the second line.
+
+* "git blame -c" did not exactly work like "git annotate" when range
+ boundaries are involved.
+
+* "git checkout file" when file is still unmerged checked out contents from
+ a random high order stage, which was confusing.
+
+* "git clone $there $here/" with extra trailing slashes after explicit
+ local directory name $here did not work as expected.
+
+* "git diff" on tracked contents with CRLF line endings did not drive "less"
+ intelligently when showing added or removed lines.
+
+* "git diff --dirstat -M" did not add changes in subdirectories up
+ correctly for renamed paths.
+
+* "git diff --cumulative" did not imply "--dirstat".
+
+* "git for-each-ref refs/heads/" did not work as expected.
+
+* "git gui" allowed users to feed patch without any context to be applied.
+
+* "git gui" botched parsing "diff" output when a line that begins with two
+ dashes and a space gets removed or a line that begins with two pluses
+ and a space gets added.
+
+* "git gui" translation updates and i18n fixes.
+
+* "git index-pack" is more careful against disk corruption while completing
+ a thin pack.
+
+* "git log -i --grep=pattern" did not ignore case; neither "git log -E
+ --grep=pattern" triggered extended regexp.
+
+* "git log --pretty="%ad" --date=short" did not use short format when
+ showing the timestamp.
+
+* "git log --author=author" match incorrectly matched with the
+ timestamp part of "author " line in commit objects.
+
+* "git log -F --author=author" did not work at all.
+
+* Build procedure for "git shell" that used stub versions of some
+ functions and globals was not understood by linkers on some platforms.
+
+* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
+ and refused to work until the user refreshed the index.
+
+* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
+ use of temporary files.
+
+* "git verify-pack -v" did not work correctly when given more than one
+ packfile.
+
+Also contains many documentation updates.

+GIT v1.6.4.3 Release Notes
+==========================
+
+Fixes since v1.6.4.2
+--------------------
+
+* "git clone" from an empty repository gave unnecessary error message,
+ even though it did everything else correctly.
+
+* "git cvsserver" invoked git commands via "git-foo" style, which has long
+ been deprecated.
+
+* "git fetch" and "git clone" had an extra sanity check to verify the
+ presence of the corresponding *.pack file before downloading *.idx
+ file by issuing a HEAD request. Github server however sometimes
+ gave 500 (Internal server error) response to HEAD even if a GET
+ request for *.pack file to the same URL would have succeeded, and broke
+ clone over HTTP from some of their repositories. As a workaround, this
+ verification has been removed (as it is not absolutely necessary).
+
+* "git grep" did not like relative pathname to refer outside the current
+ directory when run from a subdirectory.
+
+* an error message from "git push" was formatted in a very ugly way.
+
+* "git svn" did not quote the subversion user name correctly when
+ running its author-prog helper program.
+
+Other minor documentation updates are included.

+Git v1.6.5.4 Release Notes
+==========================
+
+Fixes since v1.6.5.3
+--------------------
+
+ * "git help" (without argument) used to check if you are in a directory
+ under git control. There was no breakage in behaviour per-se, but this
+ was unnecessary.
+
+ * "git prune-packed" gave progress output even when its standard error is
+ not connected to a terminal; this caused cron jobs that run it to
+ produce crufts.
+
+ * "git pack-objects --all-progress" is an option to ask progress output
+ from write-object phase _if_ progress output were to be produced, and
+ shouldn't have forced the progress output.
+
+ * "git apply -p<n> --directory=<elsewhere>" did not work well for a
+ non-default value of n.
+
+ * "git merge foo HEAD" was misparsed as an old-style invocation of the
+ command and produced a confusing error message. As it does not specify
+ any other branch to merge, it shouldn't be mistaken as such. We will
+ remove the old style "git merge <message> HEAD <commit>..." syntax in
+ future versions, but not in this release,
+
+ * "git merge -m <message> <branch>..." added the standard merge message
+ on its own after user-supplied message, which should have overridden the
+ standard one.
+
+Other minor documentation updates are included.

+ in a particular color) that is known only by newer versions of git
+ (e.g. "color.diff.func" was recently added for upcoming 1.6.6 release),

+
+* With help.autocorrect set to non-zero value, the logic to guess typos

+
+* If a command is run with an absolute path as a pathspec inside a bare

+ strlen() on NULL, which is the result of get_git_work_tree(), and
+ segfaulted.

+Git v1.6.6 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * In this release, "git fsck" defaults to "git fsck --full" and
+ checks packfiles, and because of this it will take much longer to
+ complete than before. If you prefer a quicker check only on loose
+ objects (the old default), you can say "git fsck --no-full". This
+ has been supported by 1.5.4 and newer versions of git, so it is
+ safe to write it in your script even if you use slightly older git
+ on some of your machines.
+
+Preparing yourselves for compatibility issues in 1.7.0
+------------------------------------------------------
+
+In git 1.7.0, which is planned to be the release after 1.6.6, there will
+be a handful of behaviour changes that will break backward compatibility.
+
+These changes were discussed long time ago and existing behaviours have
+been identified as more problematic to the userbase than keeping them for
+the sake of backward compatibility.
+
+When necessary, a transition strategy for existing users has been designed
+not to force them running around setting configuration variables and
+updating their scripts in order to either keep the traditional behaviour
+or adjust to the new behaviour, on the day their sysadmin decides to install
+the new version of git. When we switched from "git-foo" to "git foo" in
+1.6.0, even though the change had been advertised and the transition
+guide had been provided for a very long time, the users procrastinated
+during the entire transition period, and ended up panicking on the day
+their sysadmins updated their git installation. We are trying to avoid
+repeating that unpleasantness in the 1.7.0 release.
+
+For changes decided to be in 1.7.0, commands that will be affected
+have been much louder to strongly discourage such procrastination, and
+they continue to be in this release. If you have been using recent
+versions of git, you would have seen warnings issued when you used
+features whose behaviour will change, with a clear instruction on how
+to keep the existing behaviour if you want to. You hopefully are
+already well prepared.
+
+Of course, we have also been giving "this and that will change in
+1.7.0; prepare yourselves" warnings in the release notes and
+announcement messages for the past few releases. Let's see how well
+users will fare this time.
+
+ * "git push" into a branch that is currently checked out (i.e. pointed by
+ HEAD in a repository that is not bare) will be refused by default.
+
+ Similarly, "git push $there :$killed" to delete the branch $killed
+ in a remote repository $there, when $killed branch is the current
+ branch pointed at by its HEAD, will be refused by default.
+
+ Setting the configuration variables receive.denyCurrentBranch and
+ receive.denyDeleteCurrent to 'ignore' in the receiving repository
+ can be used to override these safety features. Versions of git
+ since 1.6.2 have issued a loud warning when you tried to do these
+ operations without setting the configuration, so repositories of
+ people who still need to be able to perform such a push should
+ already have been future proofed.
+
+ Please refer to:
+
+ http://git.or.cz/gitwiki/GitFaq#non-bare
+ http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+ for more details on the reason why this change is needed and the
+ transition process that already took place so far.
+
+ * "git send-email" will not make deep threads by default when sending a
+ patch series with more than two messages. All messages will be sent
+ as a reply to the first message, i.e. cover letter. Git 1.6.6 (this
+ release) will issue a warning about the upcoming default change, when
+ it uses the traditional "deep threading" behaviour as the built-in
+ default. To squelch the warning but still use the "deep threading"
+ behaviour, give --chain-reply-to option or set sendemail.chainreplyto
+ to true.
+
+ It has been possible to configure send-email to send "shallow thread"
+ by setting sendemail.chainreplyto configuration variable to false.
+ The only thing 1.7.0 release will do is to change the default when
+ you haven't configured that variable.
+
+ * "git status" will not be "git commit --dry-run". This change does not
+ affect you if you run the command without pathspec.
+
+ Nobody sane found the current behaviour of "git status Makefile" useful
+ nor meaningful, and it confused users. "git commit --dry-run" has been
+ provided as a way to get the current behaviour of this command since
+ 1.6.5.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+ only as a way to filter the patch output. "git diff --exit-code -b"
+ exited with non-zero status even if all changes were about changing the
+ amount of whitespace and nothing else. and "git diff -b" showed the
+ "diff --git" header line for such a change without patch text.
+
+ In 1.7.0, the "ignore whitespaces" will affect the semantics of the
+ diff operation itself. A change that does not affect anything but
+ whitespaces will be reported with zero exit status when run with
+ --exit-code, and there will not be "diff --git" header for such a
+ change.
+
+
+Updates since v1.6.5
+--------------------
+
+(subsystems)
+
+ * various gitk updates including use of themed widgets under Tk 8.5,
+ Japanese translation, a fix to a bug when running "gui blame" from
+ a subdirectory, etc.
+
+ * various git-gui updates including new translations, wm states fixes,
+ Tk bug workaround after quitting, improved heuristics to trigger gc,
+ etc.
+
+ * various git-svn updates.
+
+ * "git fetch" over http learned a new mode that is different from the
+ traditional "dumb commit walker".
+
+(portability)
+
+ * imap-send can be built on mingw port.
+
+(performance)
+
+ * "git diff -B" has smaller memory footprint.
+
+(usability, bells and whistles)
+
+ * The object replace mechanism can be bypassed with --no-replace-objects
+ global option given to the "git" program.
+
+ * In configuration files, a few variables that name paths can begin with ~/
+ and ~username/ and they are expanded as expected.
+
+ * "git subcmd -h" now shows short usage help for many more subcommands.
+
+ * "git bisect reset" can reset to an arbitrary commit.
+
+ * "git checkout frotz" when there is no local branch "frotz" but there
+ is only one remote tracking branch "frotz" is taken as a request to
+ start the named branch at the corresponding remote tracking branch.
+
+ * "git commit -c/-C/--amend" can be told with a new "--reset-author" option
+ to ignore authorship information in the commit it is taking the message
+ from.
+
+ * "git describe" can be told to add "-dirty" suffix with "--dirty" option.
+
+ * "git diff" learned --submodule option to show a list of one-line logs
+ instead of differences between the commit object names.
+
+ * "git diff" learned to honor diff.color.func configuration to paint
+ function name hint printed on the hunk header "@@ -j,k +l,m @@" line
+ in the specified color.
+
+ * "git fetch" learned --all and --multiple options, to run fetch from
+ many repositories, and --prune option to remove remote tracking
+ branches that went stale. These make "git remote update" and "git
+ remote prune" less necessary (there is no plan to remove "remote
+ update" nor "remote prune", though).
+
+ * "git fsck" by default checks the packfiles (i.e. "--full" is the
+ default); you can turn it off with "git fsck --no-full".
+
+ * "git grep" can use -F (fixed strings) and -i (ignore case) together.
+
+ * import-tars contributed fast-import frontend learned more types of
+ compressed tarballs.
+
+ * "git instaweb" knows how to talk with mod_cgid to apache2.
+
+ * "git log --decorate" shows the location of HEAD as well.
+
+ * "git log" and "git rev-list" learned to take revs and pathspecs from
+ the standard input with the new "--stdin" option.
+
+ * "--pretty=format" option to "log" family of commands learned:
+
+ . to wrap text with the "%w()" specifier.
+ . to show reflog information with "%g[sdD]" specifier.
+
+ * "git notes" command to annotate existing commits.
+
+ * "git merge" (and "git pull") learned --ff-only option to make it fail
+ if the merge does not result in a fast-forward.
+
+ * "git mergetool" learned to use p4merge.
+
+ * "git rebase -i" learned "reword" that acts like "edit" but immediately
+ starts an editor to tweak the log message without returning control to
+ the shell, which is done by "edit" to give an opportunity to tweak the
+ contents.
+
+ * "git send-email" can be told with "--envelope-sender=auto" to use the
+ same address as "From:" address as the envelope sender address.
+
+ * "git send-email" will issue a warning when it defaults to the
+ --chain-reply-to behaviour without being told by the user and
+ instructs to prepare for the change of the default in 1.7.0 release.
+
+ * In "git submodule add <repository> <path>", <path> is now optional and
+ inferred from <repository> the same way "git clone <repository>" does.
+
+ * "git svn" learned to read SVN 1.5+ and SVK merge tickets.
+
+ * "git svn" learned to recreate empty directories tracked only by SVN.
+
+ * "gitweb" can optionally render its "blame" output incrementally (this
+ requires JavaScript on the client side).
+
+ * Author names shown in gitweb output are links to search commits by the
+ author.
+
+Fixes since v1.6.5
+------------------
+
+All of the fixes in v1.6.5.X maintenance series are included in this
+release, unless otherwise noted.

+==========================

+Fixes since v1.7.0
+------------------
+
+ * In a freshly created repository "rev-parse HEAD^0" complained that
+ it is dangling symref, even though "rev-parse HEAD" didn't.
+
+ * "git show :no-such-name" tried to access the index without bounds
+ check, leading to a potential segfault.
+
+ * Message from "git cherry-pick" was harder to read and use than necessary
+ when it stopped due to conflicting changes.
+
+ * We referred to ".git/refs/" throughout the documentation when we
+ meant to talk about abstract notion of "ref namespace". Because
+ people's repositories often have packed refs these days, this was
+ confusing.
+
+ * "git diff --output=/path/that/cannot/be/written" did not correctly
+ error out.
+
+ * "git grep -e -pattern-that-begin-with-dash paths..." could not be
+ spelled as "git grep -- -pattern-that-begin-with-dash paths..." which
+ would be a GNU way to use "--" as "end of options".
+
+ * "git grep" compiled with threading support tried to access an
+ uninitialized mutex on boxes with a single CPU.
+
+ * "git stash pop -q --index" failed because the unnecessary --index
+ option was propagated to "git stash drop" that is internally run at the
+ end.
+

+
+ * "git diff --quiet -w" did not work as expected.
+
+ * "git fast-import" didn't work with a large input, as it lacked support

+ unlike the corresponding config variable and other similar options accepting

+
+Updates since v1.6.6
+--------------------
+
+(subsystems)
+
+ * "git fast-import" updates; adds "option" and "feature" to detect the

+
+(performance)
+
+ * More performance improvement patches for msysgit port.
+
+(usability, bells and whistles)
+
+ * More commands learned "--quiet" and "--[no-]progress" options.
+
+ * Various commands given by the end user (e.g. diff.type.textconv,
+ and GIT_EDITOR) can be specified with command line arguments. E.g. it
+ is now possible to say "[diff "utf8doc"] textconv = nkf -w".
+
+ * "sparse checkout" feature allows only part of the work tree to be
+ checked out.
+
+ * HTTP transfer can use authentication scheme other than basic
+ (i.e./e.g. digest).
+
+ * Switching from a version of superproject that used to have a submodule
+ to another version of superproject that no longer has it did not remove
+ the submodule directory when it should (namely, when you are not
+ interested in the submodule at all and didn't clone/checkout).
+
+ * A new attribute conflict-marker-size can be used to change the size of
+ the conflict markers from the default 7; this is useful when tracked
+ contents (e.g. git-merge documentation) have strings that resemble the
+ conflict markers.
+
+ * A new syntax "<branch>@{upstream}" can be used on the command line to
+ substitute the name of the "upstream" of the branch. Missing branch
+ defaults to the current branch, so "git fetch && git merge @{upstream}"
+ will be equivalent to "git pull".
+
+ * "git am --resolved" has a synonym "git am --continue".
+
+ * "git branch --set-upstream" can be used to update the (surprise!) upstream,
+ i.e. where the branch is supposed to pull and merge from (or rebase onto).
+
+ * "git checkout A...B" is a way to detach HEAD at the merge base between
+ A and B.
+
+ * "git checkout -m path" to reset the work tree file back into the
+ conflicted state works even when you already ran "git add path" and
+ resolved the conflicts.
+
+ * "git commit --date='<date>'" can be used to override the author date
+ just like "git commit --author='<name> <email>'" can be used to
+ override the author identity.
+
+ * "git commit --no-status" can be used to omit the listing of the index
+ and the work tree status in the editor used to prepare the log message.
+
+ * "git commit" warns a bit more aggressively until you configure user.email,
+ whose default value almost always is not (and fundamentally cannot be)
+ what you want.
+
+ * "git difftool" has been extended to make it easier to integrate it
+ with gitk.
+
+ * "git fetch --all" can now be used in place of "git remote update".
+
+ * "git grep" does not rely on external grep anymore. It can use more than
+ one thread to accelerate the operation.
+
+ * "git grep" learned "--quiet" option.
+
+ * "git log" and friends learned "--glob=heads/*" syntax that is a more
+ flexible way to complement "--branches/--tags/--remotes".
+
+ * "git merge" learned to pass options specific to strategy-backends. E.g.
+
+ - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
+ strategy how much to shift the trees explicitly.
+
+ - "git merge -Xtheirs" can be used to auto-merge as much as possible,
+ while discarding your own changes and taking merged version in
+ conflicted regions.
+
+ * "git push" learned "git push origin --delete branch", a syntactic sugar
+ for "git push origin :branch".
+
+ * "git push" learned "git push --set-upstream origin forker:forkee" that
+ lets you configure your "forker" branch to later pull from "forkee"
+ branch at "origin".
+
+ * "git rebase --onto A...B" means the history is replayed on top of the
+ merge base between A and B.
+
+ * "git rebase -i" learned new action "fixup" that squashes the change
+ but does not affect existing log message.
+
+ * "git rebase -i" also learned --autosquash option that is useful
+ together with the new "fixup" action.
+
+ * "git remote" learned set-url subcommand that updates (surprise!) url
+ for an existing remote nickname.
+
+ * "git rerere" learned "forget path" subcommand. Together with "git
+ checkout -m path" it will be useful when you recorded a wrong
+ resolution.
+
+ * Use of "git reset --merge" has become easier when resetting away a
+ conflicted mess left in the work tree.
+
+ * "git rerere" had rerere.autoupdate configuration but there was no way
+ to countermand it from the command line; --no-rerere-autoupdate option
+ given to "merge", "revert", etc. fixes this.
+
+ * "git status" learned "-s(hort)" output format.
+
+(developers)
+
+ * The infrastructure to build foreign SCM interface has been updated.
+
+ * Many more commands are now built-in.
+
+ * THREADED_DELTA_SEARCH is no more. If you build with threads, delta
+ compression will always take advantage of it.
+
+Fixes since v1.6.6
+------------------
+
+All of the fixes in v1.6.6.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git branch -d branch" used to refuse deleting the branch even when
+ the branch is fully merged to its upstream branch if it is not merged
+ to the current branch. It now deletes it in such a case.
+
+ * "filter-branch" command incorrectly said --prune-empty and --filter-commit
+ were incompatible; the latter should be read as --commit-filter.
+
+ * When using "git status" or asking "git diff" to compare the work tree
+ with something, they used to consider that a checked-out submodule with
+ uncommitted changes is not modified; this could cause people to forget
+ committing these changes in the submodule before committing in the
+ superproject. They now consider such a change as a modification and
+ "git diff" will append a "-dirty" to the work tree side when generating
+ patch output or when used with the --submodule option.

+Git v1.7.1.1 Release Notes
+==========================
+
+Fixes since v1.7.1
+------------------
+
+ * Authentication over http transport can now be made lazily, in that the
+ request can first go to a URL without username, get a 401 response and
+ then the client will ask for the username to use.
+
+ * We used to mistakenly think "../work" is a subdirectory of the current
+ directory when we are in "../work-xyz".
+
+ * The attribute mechanism now allows an entry that uses an attribute
+ macro that set/unset one attribute, immediately followed by an
+ overriding setting; this makes attribute macros much easier to use.
+
+ * We didn't recognize timezone "Z" as a synonym for "UTC" (75b37e70).
+
+ * In 1.7.0, read-tree and user commands that use the mechanism such as
+ checkout and merge were fixed to handle switching between branches one
+ of which has a file while the other has a directory at the same path
+ correctly even when there are some "confusing" pathnames in them. But
+ the algorithm used for this fix was suboptimal and had a terrible
+ performance degradation especially in larger trees.
+
+ * "git am -3" did not show diagnosis when the patch in the message was corrupt.
+
+ * After "git apply --whitespace=fix" removed trailing blank lines in an
+ patch in a patch series, it failed to apply later patches that depend
+ on the presence of such blank lines.
+
+ * "git bundle --stdin" segfaulted.
+
+ * "git checkout" and "git rebase" overwrote paths that are marked "assume
+ unchanged".
+
+ * "git commit --amend" on a commit with an invalid author-name line that
+ lacks the display name didn't work.
+
+ * "git describe" did not tie-break tags that point at the same commit
+ correctly; newer ones are preferred by paying attention to the
+ tagger date now.
+
+ * "git diff" used to tell underlying xdiff machinery to work very hard to
+ minimize the output, but this often was spending too many extra cycles
+ for very little gain.
+
+ * "git diff --color" did not paint extended diff headers per line
+ (i.e. the coloring escape sequence didn't end at the end of line),
+ which confused "less -R".
+
+ * "git fetch" over HTTP verifies the downloaded packfiles more robustly.
+
+ * The memory usage by "git index-pack" (run during "git fetch" and "git
+ push") got leaner.
+
+ * "GIT_DIR=foo.git git init --bare bar.git" created foo.git instead of bar.git.
+
+ * "git log --abbrev=$num --format='%h' ignored --abbrev=$num.
+
+ * "git ls-files ../out/side/cwd" refused to work.
+
+ * "git merge --log" used to replace the custom message given by "-m" with
+ the shortlog, instead of appending to it.
+
+ * "git notes copy" without any other argument segfaulted.
+
+ * "git pull" accepted "--dry-run", gave it to underlying "git fetch" but
+ ignored the option itself, resulting in a bogus attempt to merge
+ unrelated commit.
+
+ * "git rebase" did not faithfully reproduce a malformed author ident, that
+ is often seen in a repository converted from foreign SCMs.
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+ a nonstandard location is in use got confused.
+
+ * "git send-email" lacked a way to specify the domainname used in the
+ EHLO/HELO exchange, causing rejected connection from picky servers.
+ It learned --smtp-domain option to solve this issue.
+
+ * "git send-email" did not declare a content-transfer-encoding and
+ content-type even when its payload needs to be sent in 8-bit.
+
+ * "git show -C -C" and other corner cases lost diff metainfo output
+ in 1.7.0.
+
+ * "git stash" incorrectly lost paths in the working tree that were
+ previously removed from the index.
+
+ * "git status" stopped refreshing the index by mistake in 1.7.1.
+
+ * "git status" showed excess "hints" even when advice.statusHints is set to false.
+
+And other minor fixes and documentation updates.

+Git v1.7.1.2 Release Notes
+==========================
+

+--------------------
+
+ * "git commit" did not honor GIT_REFLOG_ACTION environment variable, resulting
+ reflog messages for cherry-pick and revert actions to be recorded as "commit".
+
+ * "git clone/fetch/pull" issued an incorrect error message when a ref and
+ a symref that points to the ref were updated at the same time. This
+ obviously would update them to the same value, and should not result in
+ an error condition.
+
+ * "git diff" inside a tree with many pathnames that have certain
+ characters has become very slow in 1.7.0 by mistake.
+
+ * "git rev-parse --parseopt --stop-at-non-option" did not stop at non option
+ when --keep-dashdash was in effect.
+
+ * An overlong line after ".gitdir: " in a git file caused out of bounds
+ access to an array on the stack.
+
+ * "git config --path conf.var" to attempt to expand a variable conf.var
+ that uses "~/" short-hand segfaulted when $HOME environment variable
+ was not set.

+Git v1.7.1 Release Notes
+========================
+
+Updates since v1.7.0
+--------------------
+
+ * Eric Raymond is the maintainer of updated CIAbot scripts, in contrib/.
+
+ * gitk updates.
+
+ * Some commands (e.g. svn and http interfaces) that interactively ask
+ for a password can be told to use an external program given via
+ GIT_ASKPASS.
+
+ * Conflict markers that lead the common ancestor in diff3-style output
+ now have a label, which hopefully would help third-party tools that
+ expect one.
+
+ * Comes with an updated bash-completion script.
+
+ * "git am" learned "--keep-cr" option to handle inputs that are
+ a mixture of changes to files with and without CRLF line endings.
+
+ * "git cvsimport" learned -R option to leave revision mapping between
+ CVS revisions and resulting git commits.
+
+ * "git diff --submodule" notices and describes dirty submodules.
+
+ * "git for-each-ref" learned %(symref), %(symref:short) and %(flag)
+ tokens.
+
+ * "git hash-object --stdin-paths" can take "--no-filters" option now.
+
+ * "git init" can be told to look at init.templatedir configuration
+ variable (obviously that has to come from either /etc/gitconfig or
+ $HOME/.gitconfig).
+
+ * "git grep" learned "--no-index" option, to search inside contents that
+ are not managed by git.
+
+ * "git grep" learned --color=auto/always/never.
+
+ * "git grep" learned to paint filename and line-number in colors.
+
+ * "git log -p --first-parent -m" shows one-parent diff for merge
+ commits, instead of showing combined diff.
+
+ * "git merge-file" learned to use custom conflict marker size and also
+ to use the "union merge" behaviour.
+
+ * "git notes" command has been rewritten in C and learned many commands
+ and features to help you carry notes forward across rebases and amends.
+
+ * "git request-pull" identifies the commit the request is relative to in
+ a more readable way.
+
+ * "git reset" learned "--keep" option that lets you discard commits
+ near the tip while preserving your local changes in a way similar
+ to how "git checkout branch" does.
+
+ * "git status" notices and describes dirty submodules.
+
+ * "git svn" should work better when interacting with repositories
+ with CRLF line endings.
+
+ * "git imap-send" learned to support CRAM-MD5 authentication.
+
+ * "gitweb" installation procedure can use "minified" js/css files
+ better.
+
+ * Various documentation updates.
+
+Fixes since v1.7.0
+------------------
+
+All of the fixes in v1.7.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git add frotz/nitfol" did not complain when the entire frotz/ directory
+ was ignored.
+
+ * "git diff --stat" used "int" to count the size of differences,
+ which could result in overflowing.
+
+ * "git rev-list --pretty=oneline" didn't terminate a record with LF for
+ commits without any message.
+
+ * "git rev-list --abbrev-commit" defaulted to 40-byte abbreviations, unlike
+ newer tools in the git toolset.

+Git v1.7.2 Release Notes
+========================
+
+Updates since v1.7.1
+--------------------
+
+ * core.eol configuration and text/eol attributes are the new way to control
+ the end of line conventions for files in the working tree.
+
+ * core.autocrlf has been made safer - it will now only handle line
+ endings for new files and files that are LF-only in the
+ repository. To normalize content that has been checked in with
+ CRLF, use the new eol/text attributes.
+
+ * The whitespace rules used in "git apply --whitespace" and "git diff"
+ gained a new member in the family (tab-in-indent) to help projects with
+ policy to indent only with spaces.
+
+ * When working from a subdirectory, by default, git does not look for its
+ metadirectory ".git" across filesystems, primarily to help people who
+ have invocations of git in their custom PS1 prompts, as being outside
+ of a git repository would look for ".git" all the way up to the root
+ directory, and NFS mounts are often slow. DISCOVERY_ACROSS_FILESYSTEM
+ environment variable can be used to tell git not to stop at a
+ filesystem boundary.
+
+ * Usage help messages generated by parse-options library (i.e. most
+ of the Porcelain commands) are sent to the standard output now.
+
+ * ':/<string>' notation to look for a commit now takes regular expression
+ and it is not anchored at the beginning of the commit log message
+ anymore (this is a backward incompatible change).
+
+ * "git" wrapper learned "-c name=value" option to override configuration
+ variable from the command line.
+
+ * Improved portability for various platforms including older SunOS,
+ HP-UX 10/11, AIX, Tru64, etc. and platforms with Python 2.4.
+
+ * The message from "git am -3" has been improved when conflict
+ resolution ended up making the patch a no-op.
+
+ * "git blame" applies the textconv filter to the contents it works
+ on, when available.
+
+ * "git checkout --orphan newbranch" is similar to "-b newbranch" but
+ prepares to create a root commit that is not connected to any existing
+ commit.
+
+ * "git cherry-pick" learned to pick a range of commits
+ (e.g. "cherry-pick A..B" and "cherry-pick --stdin"), so did "git
+ revert"; these do not support the nicer sequencing control "rebase
+ [-i]" has, though.
+
+ * "git cherry-pick" and "git revert" learned --strategy option to specify
+ the merge strategy to be used when performing three-way merges.
+
+ * "git cvsserver" can be told to use pserver; its password file can be
+ stored outside the repository.
+
+ * The output from the textconv filter used by "git diff" can be cached to
+ speed up their reuse.
+
+ * "git diff --word-diff=<mode>" extends the existing "--color-words"
+ option, making it more useful in color-challenged environments.
+
+ * The regexp to detect function headers used by "git diff" for PHP has
+ been enhanced for visibility modifiers (public, protected, etc.) to
+ better support PHP5.
+
+ * "diff.noprefix" configuration variable can be used to implicitly
+ ask for "diff --no-prefix" behaviour.
+
+ * "git for-each-ref" learned "%(objectname:short)" that gives the object
+ name abbreviated.
+
+ * "git format-patch" learned --signature option and format.signature
+ configuration variable to customize the e-mail signature used in the
+ output.
+
+ * Various options to "git grep" (e.g. --count, --name-only) work better
+ with binary files.
+
+ * "git grep" learned "-Ovi" to open the files with hits in your editor.
+
+ * "git help -w" learned "chrome" and "chromium" browsers.
+
+ * "git log --decorate" shows commit decorations in various colours.
+
+ * "git log --follow <path>" follows across copies (it used to only follow
+ renames). This may make the processing more expensive.
+
+ * "git log --pretty=format:<template>" specifier learned "% <something>"
+ magic that inserts a space only when %<something> expands to a
+ non-empty string; this is similar to "%+<something>" magic, but is
+ useful in a context to generate a single line output.
+
+ * "git notes prune" learned "-n" (dry-run) and "-v" options, similar to
+ what "git prune" has.
+
+ * "git patch-id" can be fed a mbox without getting confused by the
+ signature line in the format-patch output.
+
+ * "git remote" learned "set-branches" subcommand.
+
+ * "git rev-list A..B" learned --ancestry-path option to further limit
+ the result to the commits that are on the ancestry chain between A and
+ B (i.e. commits that are not descendants of A are excluded).
+
+ * "git show -5" is equivalent to "git show --do-walk 5"; this is similar
+ to the update to make "git show master..next" walk the history,
+ introduced in 1.6.4.
+
+ * "git status [-s] --ignored" can be used to list ignored paths.
+
+ * "git status -s -b" shows the current branch in the output.
+
+ * "git status" learned "--ignore-submodules" option.
+
+ * Various "gitweb" enhancements and clean-ups, including syntax
+ highlighting, "plackup" support for instaweb, .fcgi suffix to run
+ it as FastCGI script, etc.
+
+ * The test harness has been updated to produce TAP-friendly output.
+
+ * Many documentation improvement patches are also included.
+
+
+Fixes since v1.7.1
+------------------
+
+All of the fixes in v1.7.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * We didn't URL decode "file:///path/to/repo" correctly when path/to/repo
+ had percent-encoded characters (638794c, 9d2e942, ce83eda, 3c73a1d).
+
+ * "git clone" did not configure remote.origin.url correctly for bare
+ clones (df61c889).
+
+ * "git diff --graph" works better with "--color-words" and other options
+ (81fa024..4297c0a).
+
+ * "git diff" could show ambiguous abbreviation of blob object names on
+ its "index" line (3e5a188).
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+ a nonstandard location is in use got confused (560fb6a1).
+
+ * "git read-tree -m A B" used to switch to branch B while retaining
+ local changes added an incorrect cache-tree information (b1f47514).

+Git v1.7.3.3 Release Notes
+==========================
+
+In addition to the usual fixes, this release also includes support for
+the new "add.ignoreErrors" name given to the existing "add.ignore-errors"
+configuration variable.
+
+The next version, Git 1.7.4, and future versions, will support both
+old and incorrect name and the new corrected name, but without this
+backport, users who want to use the new name "add.ignoreErrors" in
+their repositories cannot use older versions of Git.
+
+Fixes since v1.7.3.2
+--------------------
+
+ * "git apply" segfaulted when a bogus input is fed to it.
+
+ * Running "git cherry-pick --ff" on a root commit segfaulted.
+
+ * "diff", "blame" and friends incorrectly applied textconv filters to
+ symlinks.
+
+ * Highlighting of whitespace breakage in "diff" output was showing
+ incorrect amount of whitespaces when blank-at-eol is set and the line
+ consisted only of whitespaces and a TAB.
+
+ * "diff" was overly inefficient when trying to find the line to use for
+ the function header (i.e. equivalent to --show-c-function of GNU diff).
+
+ * "git imap-send" depends on libcrypto but our build rule relied on the
+ linker to implicitly link it via libssl, which was wrong.
+
+ * "git merge-file" can be called from within a subdirectory now.
+
+ * "git repack -f" expanded and recompressed non-delta objects in the
+ existing pack, which was wasteful. Use new "-F" option if you really
+ want to (e.g. when changing the pack.compression level).
+
+ * "git rev-list --format="...%x00..." incorrectly chopped its output
+ at NUL.
+
+ * "git send-email" did not correctly remove duplicate mail addresses from
+ the Cc: header that appear on the To: header.
+
+ * The completion script (in contrib/completion) ignored lightweight tags
+ in __git_ps1().
+
+ * "git-blame" mode (in contrib/emacs) didn't say (require 'format-spec)
+ even though it depends on it; it didn't work with Emacs 22 or older
+ unless Gnus is used.
+
+ * "git-p4" (in contrib/) did not correctly handle deleted files.
+
+Other minor fixes and documentation updates are also included.

+Git v1.7.3.4 Release Notes
+==========================
+
+Fixes since v1.7.3.3
+--------------------
+
+ * Smart HTTP transport used to incorrectly retry redirected POST
+ request with GET request.
+
+ * "git apply" did not correctly handle patches that only change modes
+ if told to apply while stripping leading paths with -p option.
+
+ * "git apply" can deal with patches with timezone formatted with a
+ colon between the hours and minutes part (e.g. "-08:00" instead of
+ "-0800").
+
+ * "git checkout" removed an untracked file "foo" from the working
+ tree when switching to a branch that contains a tracked path
+ "foo/bar". Prevent this, just like the case where the conflicting
+ path were "foo" (c752e7f..7980872d).
+
+ * "git cherry-pick" or "git revert" refused to work when a path that
+ would be modified by the operation was stat-dirty without a real
+ difference in the contents of the file.
+
+ * "git diff --check" reported an incorrect line number for added
+ blank lines at the end of file.
+
+ * "git imap-send" failed to build under NO_OPENSSL.
+
+ * Setting log.decorate configuration variable to "0" or "1" to mean
+ "false" or "true" did not work.
+
+ * "git push" over dumb HTTP protocol did not work against WebDAV
+ servers that did not terminate a collection name with a slash.
+
+ * "git tag -v" did not work with GPG signatures in rfc1991 mode.
+
+ * The post-receive-email sample hook was accidentally broken in 1.7.3.3
+ update.
+
+ * "gitweb" can sometimes be tricked into parrotting a filename argument
+ given in a request without properly quoting.
+
+Other minor fixes and documentation updates are also included.

+Git 1.7.3.5 Release Notes
+=========================
+
+ * The xfuncname pattern used by "git diff" and "git grep" to show the
+ last notable line in context were broken for python and ruby for a long
+ time.
+
+ * "git merge" into an unborn branch removed an untracked file "foo" from
+ the working tree when merged branch had "foo" (this fix was already in
+ 1.7.3.3 but was omitted from the release notes by mistake).
+
+ * "git status -s" did not quote unprintable characters in paths as
+ documented.
+
+ * "git am --abort" used to always reset to the commit at the beginning of
+ the last "am" invocation that has stopped, losing any unrelated commits
+ that may have been made since then. Now it refrains from doing so and
+ instead issues a warning.
+
+ * "git blame" incorrectly reused bogusly cached result of textconv
+ filter for files from the working tree.
+
+ * "git commit" used to abort after the user edited the log message
+ when the committer information was not correctly set up. It now
+ aborts before starting the editor.
+
+ * "git commit --date=invalid" used to silently ignore the incorrectly
+ specified date; it is now diagnosed as an error.
+
+ * "git rebase --skip" to skip the last commit in a series used to fail
+ to run post-rewrite hook and to copy notes from old commits that have
+ successfully been rebased so far. Now it do (backmerge ef88ad2).
+
+ * "gitweb" tried to show a wrong feed logo when none was specified.

+Git v1.7.3 Release Notes
+========================
+
+Updates since v1.7.2
+--------------------
+
+ * git-gui, now at version 0.13.0, got various updates and a new
+ maintainer, Pat Thoyts.
+
+ * Gitweb allows its configuration to change per each request; it used to
+ read the configuration once upon startup.
+
+ * When git finds a corrupt object, it now reports the file that contains
+ it.
+
+ * "git checkout -B <it>" is a shorter way to say "git branch -f <it>"
+ followed by "git checkout <it>".
+
+ * When "git checkout" or "git merge" refuse to proceed in order to
+ protect local modification to your working tree, they used to stop
+ after showing just one path that might be lost. They now show all,
+ in a format that is easier to read.
+
+ * "git clean" learned "-e" ("--exclude") option.
+
+ * Hunk headers produced for C# files by "git diff" and friends show more
+ relevant context than before.
+
+ * diff.ignoresubmodules configuration variable can be used to squelch the
+ differences in submodules reported when running commands (e.g. "diff",
+ "status", etc.) at the superproject level.
+
+ * http.useragent configuration can be used to lie who you are to your
+ restrictive firewall.
+
+ * "git rebase --strategy <s>" learned "-X" option to pass extra options
+ that are understood by the chosen merge strategy.
+
+ * "git rebase -i" learned "exec" that you can insert into the insn sheet
+ to run a command between its steps.
+
+ * "git rebase" between branches that have many binary changes that do
+ not conflict should be faster.
+
+ * "git rebase -i" peeks into rebase.autosquash configuration and acts as
+ if you gave --autosquash from the command line.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.2
+------------------
+
+All of the fixes in v1.7.2.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git merge -s recursive" (which is the default) did not handle cases
+ where a directory becomes a file (or vice versa) very well.
+
+ * "git fetch" and friends were accidentally broken for url with "+" in
+ its path, e.g. "git://git.gnome.org/gtk+".
+
+ * "git fetch $url" (i.e. without refspecs) was broken for quite some
+ time, if the current branch happen to be tracking some remote.
+
+ * "git ls-tree dir dirgarbage", when "dir" was a directory,
+ incorrectly recursed into "dir".
+
+ * "git note remove" created unnecessary extra commit when named object
+ did not have any note to begin with.
+
+ * "git rebase" did not work well if you had diff.noprefix configured.
+
+ * "git -c foo=bar subcmd" did not work well for subcmd that is not
+ implemented as a built-in command.

+==========================
+
+Fixes since v1.7.4.1
+--------------------
+
+ * Many documentation updates to match "git cmd -h" output and the
+ git-cmd manual page.
+
+ * We used to keep one file descriptor open for each and every packfile
+ that we have a mmap window on it (read: "in use"), even when for very
+ tiny packfiles. We now close the file descriptor early when the entire
+ packfile fits inside one mmap window.
+
+ * "git bisect visualize" tried to run "gitk" in windowing
+ environments even when "gitk" is not installed, resulting in a
+ strange error message.
+
+ * "git clone /no/such/path" did not fail correctly.
+
+ * "git commit" did not correctly error out when the user asked to use a
+ non existent file as the commit message template.
+
+ * "git diff --stat -B" ran on binary files counted the changes in lines,
+ which was nonsensical.
+
+ * "git diff -M" opportunistically detected copies, which was not
+ necessarily a good thing, especially when it is internally run by
+ recursive merge.
+
+ * "git difftool" didn't tell (g)vimdiff that the files it is reading are
+ to be opened read-only.
+
+ * "git merge" didn't pay attention to prepare-commit-msg hook, even
+ though if a merge is conflicted and manually resolved, the subsequent
+ "git commit" would have triggered the hook, which was inconsistent.
+
+ * "git patch-id" (and commands like "format-patch --ignore-in-upstream"
+ that use it as their internal logic) handled changes to files that end
+ with incomplete lines incorrectly.
+
+ * The official value to tell "git push" to push the current branch back
+ to update the upstream branch it forked from is now called "upstream".
+ The old name "tracking" is and will be supported.
+
+ * "git submodule update" used to honor the --merge/--rebase option (or
+ corresponding configuration variables) even for a newly cloned
+ subproject, which made no sense (so/submodule-no-update-first-time).
+
+ * gitweb's "highlight" interface mishandled tabs.
+
+ * gitweb didn't understand timezones with GMT offset that is not
+ multiple of a whole hour.
+
+ * gitweb had a few forward-incompatible syntactic constructs and
+ also used incorrect variable when showing the file mode in a diff.

+Git v1.7.4 Release Notes
+========================
+
+Updates since v1.7.3
+--------------------
+
+ * The documentation Makefile now assumes by default asciidoc 8 and
+ docbook-xsl >= 1.73. If you have older versions, you can set
+ ASCIIDOC7 and ASCIIDOC_ROFF, respectively.
+
+ * The option parsers of various commands that create new branches (or
+ rename existing ones to a new name) were too loose and users were
+ allowed to give a branch a name that begins with a dash by creative
+ abuse of their command line options, which only led to burning
+ themselves. The name of a branch cannot begin with a dash now.
+
+ * System-wide fallback default attributes can be stored in
+ /etc/gitattributes; the core.attributesfile configuration variable can
+ be used to customize the path to this file.
+
+ * The thread structure generated by "git send-email" has changed
+ slightly. Setting the cover letter of the latest series as a reply
+ to the cover letter of the previous series with --in-reply-to used
+ to make the new cover letter and all the patches replies to the
+ cover letter of the previous series; this has been changed to make
+ the patches in the new series replies to the new cover letter.
+
+ * The Bash completion script in contrib/ has been adjusted to be usable with
+ Bash 4 (options with '=value' didn't complete). It has been also made
+ usable with zsh.
+
+ * Different pagers can be chosen depending on which subcommand is
+ being run under the pager, using the "pager.<subcommand>" variable.
+
+ * The hardcoded tab-width of 8 that is used in whitespace breakage checks is now
+ configurable via the attributes mechanism.
+
+ * Support of case insensitive filesystems (i.e. "core.ignorecase") has
+ been improved. For example, the gitignore mechanism didn't pay attention
+ to case insensitivity.
+
+ * The <tree>:<path> syntax for naming a blob in a tree, and the :<path>
+ syntax for naming a blob in the index (e.g. "master:Makefile",
+ ":hello.c") have been extended. You can start <path> with "./" to
+ implicitly have the (sub)directory you are in prefixed to the
+ lookup. Similarly, ":../Makefile" from a subdirectory would mean
+ "the Makefile of the parent directory in the index".
+
+ * "git blame" learned the --show-email option to display the e-mail
+ addresses instead of the names of authors.
+
+ * "git commit" learned the --fixup and --squash options to help later invocation
+ of interactive rebase.
+
+ * Command line options to "git cvsimport" whose names are in capital
+ letters (-A, -M, -R and -S) can now be specified as the default in
+ the .git/config file by their longer names (cvsimport.authorsFile,
+ cvsimport.mergeRegex, cvsimport.trackRevisions, cvsimport.ignorePaths).
+
+ * "git daemon" can be built in the MinGW environment.
+
+ * "git daemon" can take more than one --listen option to listen to
+ multiple addresses.
+
+ * "git describe --exact-match" was optimized not to read commit
+ objects unnecessarily.
+
+ * "git diff" and "git grep" learned what functions and subroutines
+ in Fortran, Pascal and Perl look like.
+
+ * "git fetch" learned the "--recurse-submodules" option.
+
+ * "git mergetool" tells vim/gvim to show a three-way diff by default
+ (use vimdiff2/gvimdiff2 as the tool name for old behavior).
+
+ * "git log -G<pattern>" limits the output to commits whose change has
+ added or deleted lines that match the given pattern.
+
+ * "git read-tree" with no argument as a way to empty the index is
+ deprecated; we might want to remove it in the future. Users can
+ use the new --empty option to be more explicit instead.
+
+ * "git repack -f" does not spend cycles to recompress objects in the
+ non-delta representation anymore (use -F if you really mean it
+ e.g. after you changed the core.compression variable setting).
+
+ * "git merge --log" used to limit the resulting merge log to 20
+ entries; this is now customizable by giving e.g. "--log=47".
+
+ * "git merge" may work better when all files were moved out of a
+ directory in one branch while a new file is created in place of that
+ directory in the other branch.
+
+ * "git merge" learned the "--abort" option, synonymous to
+ "git reset --merge" when a merge is in progress.
+
+ * "git notes" learned the "merge" subcommand to merge notes refs.
+ In addition to the default manual conflict resolution, there are
+ also several notes merge strategies for automatically resolving
+ notes merge conflicts.
+
+ * "git rebase --autosquash" can use SHA-1 object names to name the
+ commit which is to be fixed up (e.g. "fixup! e83c5163").
+
+ * The default "recursive" merge strategy learned the --rename-threshold
+ option to influence the rename detection, similar to the -M option
+ of "git diff". From the "git merge" frontend, the "-X<strategy option>"
+ interface, e.g. "git merge -Xrename-threshold=50% ...", can be used
+ to trigger this.
+
+ * The "recursive" strategy also learned to ignore various whitespace
+ changes; the most notable is -Xignore-space-at-eol.
+
+ * "git send-email" learned "--to-cmd", similar to "--cc-cmd", to read
+ the recipient list from a command output.
+
+ * "git send-email" learned to read and use "To:" from its input files.
+
+ * you can extend "git shell", which is often used on boxes that allow
+ git-only login over ssh as login shell, with a custom set of
+ commands.
+
+ * The current branch name in "git status" output can be colored differently
+ from the generic header color by setting the "color.status.branch" variable.
+
+ * "git submodule sync" updates metainformation for all submodules,
+ not just the ones that have been checked out.
+
+ * gitweb can use a custom 'highlight' command with its configuration file.
+
+ * other gitweb updates.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.3
+------------------
+
+All of the fixes in the v1.7.3.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git log --author=me --author=her" did not find commits written by
+ me or by her; instead it looked for commits written by me and by
+ her, which is impossible.
+
+ * "git push --progress" shows progress indicators now.
+
+ * "git rebase -i" showed a confusing error message when given a
+ branch name that does not exist.
+
+ * "git repack" places its temporary packs under $GIT_OBJECT_DIRECTORY/pack
+ instead of $GIT_OBJECT_DIRECTORY/ to avoid cross directory renames.
+
+ * "git submodule update --recursive --other-flags" passes flags down
+ to its subinvocations.

+Git v1.7.5.1 Release Notes
+==========================
+
+Fixes since v1.7.5
+------------------
+
+ * When an object "$tree:$path" does not exist, if $path does exist in the
+ subtree of $tree that corresponds to the subdirectory the user is in,
+ git now suggests using "$tree:./$path" in addition to the advice to use
+ the full path from the root of the working tree.
+
+ * The "--date=relative" output format used to say "X years, 12 months"
+ when it should have said "X+1 years".
+
+ * The smart-HTTP transfer was broken in 1.7.5 when the client needs
+ to issue a small POST (which uses content-length) and then a large
+ POST (which uses chunked) back to back.
+
+ * "git clean" used to fail on an empty directory that is not readable,
+ even though rmdir(2) could remove such a directory. Now we attempt it
+ as the last resort.
+
+ * The "--dirstat" option of "diff" family of commands used to totally
+ ignore a change that only rearranged lines within a file. Such a
+ change now counts as at least a minimum but non zero change.
+
+ * The "--dirstat" option of "diff" family of commands used to use the
+ pathname in the original, instead of the pathname in the result,
+ when renames are involved.
+
+ * "git pack-object" did not take core.bigfilethreashold into account
+ (unlike fast-import); now it does.
+
+ * "git reflog" ignored options like "--format=.." on the command line.
+
+ * "git stash apply" used to refuse to work if there was any change in
+ the working tree, even when the change did not overlap with the change
+ the stash recorded.
+
+ * "git stash apply @{99999}" was not diagnosed as an error, even when you

+Git v1.7.5.2 Release Notes
+==========================
+
+The release notes to 1.7.5.1 forgot to mention:
+
+ * "git stash -p --no-keep-index" and "git stash --no-keep-index -p" now
+ mean the same thing.
+
+ * "git upload-pack" (hence "git push" over git native protocol) had a
+ subtle race condition that could lead to a deadlock.
+
+Fixes since v1.7.5.1
+--------------------
+
+ * "git add -p" did not work correctly when a hunk is split and then
+ one of them was given to the editor.
+
+ * "git add -u" did not resolve a conflict where our history deleted and
+ their history modified the same file, and the working tree resolved to
+ keep a file.
+
+ * "git cvsimport" did not know that CVSNT stores its password file in a
+ location different from the traditional CVS.
+
+ * "git diff-files" did not show the mode information from the working
+ tree side of an unmerged path correctly.
+
+ * "git diff -M --cached" used to use unmerged path as a possible rename
+ source candidate, which made no sense.
+
+ * The option name parser in "git fast-import" used prefix matches for
+ some options where it shouldn't, and accepted non-existent options,
+ e.g. "--relative-marksmith" or "--forceps".
+
+ * "git format-patch" did not quote RFC822 special characters in the
+ email address (e.g From: Junio C. Hamano <jch@example.com>, not
+ From: "Junio C. Hamano" <jch@example.com>).
+
+ * "git format-patch" when run with "--quiet" option used to produce a
+ nonsense result that consists of alternating empty output.
+
+ * In "git merge", per-branch branch.<name>.mergeoptions configuration
+ variables did not override the fallback default merge.<option>
+ configuration variables such as merge.ff, merge.log, etc.
+
+ * "git merge-one-file" did not honor GIT_WORK_TREE settings when
+ handling a "both sides added, differently" conflict.
+
+ * "git mergetool" did not handle conflicted submoudules gracefully.
+
+ * "git-p4" (in contrib) used a wrong base image while merge a file that
+ was added on both branches differently.
+
+ * "git rebase -i -p" failed to preserve the history when there is a
+ redundant merge created with the --no-ff option.
+
+And other minor fixes and documentation updates.

+Git v1.7.5.3 Release Notes
+==========================
+
+Fixes since v1.7.5.2
+--------------------
+
+ * The bash completion scripts should correctly work using zsh's bash
+ completion emulation layer now.
+
+ * Setting $(prefix) in config.mak did not affect where etc/gitconfig
+ file is read from, even though passing it from the command line of
+ $(MAKE) did.
+
+ * The logic to handle "&" (expand to UNIX username) in GECOS field
+ miscounted the length of the name it formatted.
+
+ * "git cherry-pick -s resolve" failed to cherry-pick a root commit.
+
+ * "git diff --word-diff" misbehaved when diff.suppress-blank-empty was
+ in effect.
+
+ * "git log --stdin path" with an input that has additional pathspec
+ used to corrupt memory.
+
+ * "git send-pack" (hence "git push") over smalt-HTTP protocol could
+ deadlock when the client side pack-object died early.
+
+ * Compressed tarball gitweb generates used to be made with the timestamp
+ of the tarball generation; this was bad because snapshot from the same
+ tree should result in a same tarball.
+
+And other minor fixes and documentation updates.

+Git v1.7.5.4 Release Notes
+==========================
+
+Fixes since v1.7.5.3
+--------------------
+
+ * The single-key mode of "git add -p" was easily fooled into thinking
+ that it was told to add everthing ('a') when up-arrow was pressed by
+ mistake.
+
+ * Setting a git command that uses custom configuration via "-c var=val"
+ as an alias caused a crash due to a realloc(3) failure.
+
+ * "git diff -C -C" used to disable the rename detection entirely when
+ there are too many copy candidate paths in the tree; now it falls
+ back to "-C" when doing so would keep the copy candidate paths
+ under the rename detection limit.
+
+ * "git rerere" did not diagnose a corrupt MERGE_RR file in some cases.
+
+And other minor fixes and documentation updates.

+Git v1.7.5 Release Notes
+========================
+
+Updates since v1.7.4
+--------------------
+
+ * Various MinGW portability fixes.
+
+ * Various git-p4 enhancements (in contrib).
+
+ * Various vcs-svn, git-svn and gitk enhancements and fixes.
+
+ * Various git-gui updates (0.14.0).
+
+ * Update to more modern HP-UX port.
+
+ * The codebase is getting prepared for i18n/l10n; no translated
+ strings nor translation mechanism in the code yet, but the strings
+ are being marked for l10n.
+
+ * The bash completion script can now complete symmetric difference
+ for "git diff" command, e.g. "git diff ...bra<TAB>".
+
+ * The default minimum length of abbreviated and unique object names
+ can now be configured by setting the core.abbrev configuration
+ variable.
+
+ * "git apply -v" reports offset lines when the patch does not apply at
+ the exact location recorded in the diff output.
+
+ * "git config" used to be also known as "git repo-config", but the old
+ name is now officially deprecated.
+
+ * "git checkout --detach <commit>" is a more user friendly synonym for
+ "git checkout <commit>^0".
+
+ * "git checkout" performed on detached HEAD gives a warning and
+ advice when the commit being left behind will become unreachable from
+ any branch or tag.
+
+ * "git cherry-pick" and "git revert" can be told to use a custom merge
+ strategy, similar to "git rebase".
+
+ * "git cherry-pick" remembers which commit failed to apply when it is
+ stopped by conflicts, making it unnecessary to use "commit -c $commit"
+ to conclude it.
+
+ * "git cvsimport" bails out immediately when the cvs server cannot be
+ reached, without spewing unnecessary error messages that complain about
+ the server response it never got.
+
+ * "git fetch" vs "git upload-pack" transfer learned 'no-done'
+ protocol extension to save one round-trip after the content
+ negotiation is done. This saves one HTTP RPC, reducing the overall
+ latency for a trivial fetch.
+
+ * "git fetch" can be told to recursively fetch submodules on-demand.
+
+ * "git grep -f <filename>" learned to treat "-" as "read from the
+ standard input stream".
+
+ * "git grep --no-index" did not honor pathspecs correctly, returning
+ paths outside the specified area.
+
+ * "git init" learned the --separate-git-dir option to allow the git
+ directory for a new repository created elsewhere and linked via the
+ gitdir mechanism. This is primarily to help submodule support later
+ to switch between a branch of superproject that has the submodule
+ and another that does not.
+
+ * "git log" type commands now understand globbing pathspecs. You
+ can say "git log -- '*.txt'" for example.
+
+ * "git log" family of commands learned --cherry and --cherry-mark
+ options that can be used to view two diverged branches while omitting
+ or highlighting equivalent changes that appear on both sides of a
+ symmetric difference (e.g. "log --cherry A...B").
+
+ * A lazy "git merge" that didn't say what to merge used to be an error.
+ When run on a branch that has an upstream defined, however, the command
+ now merges from the configured upstream.
+
+ * "git mergetool" learned how to drive "beyond compare 3" as well.
+
+ * "git rerere forget" without pathspec used to forget all the saved
+ conflicts that relate to the current merge; it now requires you to
+ give it pathspecs.
+
+ * "git rev-list --objects $revs -- $pathspec" now limits the objects listed
+ in its output properly with the pathspec, in preparation for narrow
+ clones.
+
+ * "git push" with no parameters gives better advice messages when
+ "tracking" is used as the push.default semantics or there is no remote
+ configured yet.
+
+ * A possible value to the "push.default" configuration variable,
+ 'tracking', gained a synonym that more naturally describes what it
+ does, 'upstream'.
+
+ * "git rerere" learned a new subcommand "remaining" that is similar to
+ "status" and lists the paths that had conflicts which are known to
+ rerere, but excludes the paths that have already been marked as
+ resolved in the index from its output. "git mergetool" has been
+ updated to use this facility.
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.4
+------------------
+
+All of the fixes in the v1.7.4.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git fetch" from a client that is mostly following the remote
+ needlessly told all of its refs to the server for both sides to
+ compute the set of objects that need to be transferred efficiently,
+ instead of stopping when the server heard enough. In a project with
+ many tags, this turns out to be extremely wasteful, especially over
+ the smart HTTP transport (sp/maint-{upload,fetch}-pack-stop-early~1).
+
+ * "git fetch" run from a repository that uses the same repository as
+ its alternate object store as the repository it is fetching from
+ did not tell the server that it already has access to objects
+ reachable from the refs in their common alternate object store,
+ causing it to fetch unnecessary objects (jc/maint-fetch-alt).
+
+ * "git remote add --mirror" created a configuration that is suitable for
+ doing both a mirror fetch and a mirror push at the same time, which
+ made little sense. We now warn and require the command line to specify
+ either --mirror=fetch or --mirror=push.

+Git v1.7.6.1 Release Notes
+==========================
+
+Fixes since v1.7.6
+------------------
+
+ * Various codepaths that invoked zlib deflate/inflate assumed that these
+ functions can compress or uncompress more than 4GB data in one call on
+ platforms with 64-bit long, which has been corrected.
+
+ * "git unexecutable" reported that "unexecutable" was not found, even
+ though the actual error was that "unexecutable" was found but did
+ not have a proper she-bang line to be executed.
+
+ * Error exits from $PAGER were silently ignored.
+
+ * "git checkout -b <branch>" was confused when attempting to create a
+ branch whose name ends with "-g" followed by hexadecimal digits,
+ and refused to work.
+
+ * "git checkout -b <branch>" sometimes wrote a bogus reflog entry,
+ causing later "git checkout -" to fail.
+
+ * "git diff --cc" learned to correctly ignore binary files.
+
+ * "git diff -c/--cc" mishandled a deletion that resolves a conflict, and
+ looked in the working tree instead.
+
+ * "git fast-export" forgot to quote pathnames with unsafe characters
+ in its output.
+
+ * "git fetch" over smart-http transport used to abort when the
+ repository was updated between the initial connection and the
+ subsequent object transfer.
+
+ * "git fetch" did not recurse into submodules in subdirectories.
+
+ * "git ls-tree" did not error out when asked to show a corrupt tree.
+
+ * "git pull" without any argument left an extra whitespace after the
+ command name in its reflog.
+
+ * "git push --quiet" was not really quiet.
+
+ * "git rebase -i -p" incorrectly dropped commits from side branches.
+
+ * "git reset [<commit>] paths..." did not reset the index entry correctly
+ for unmerged paths.
+
+ * "git submodule add" did not allow a relative repository path when
+ the superproject did not have any default remote url.
+
+ * "git submodule foreach" failed to correctly give the standard input to
+ the user-supplied command it invoked.
+
+ * submodules that the user has never showed interest in by running
+ "git submodule init" was incorrectly marked as interesting by "git
+ submodule sync".
+
+ * "git submodule update --quiet" was not really quiet.
+
+ * "git tag -l <glob>..." did not take multiple glob patterns from the
+ command line.

+Git v1.7.6 Release Notes
+========================
+
+Updates since v1.7.5
+--------------------
+
+ * Various git-svn updates.
+
+ * Updates the way content tags are handled in gitweb. Also adds
+ a UI to choose common timezone for displaying the dates.
+
+ * Similar to branch names, tagnames that begin with "-" are now
+ disallowed.
+
+ * Clean-up of the C part of i18n (but not l10n---please wait)
+ continues.
+
+ * The scripting part of the codebase is getting prepared for i18n/l10n.
+
+ * Pushing and pulling from a repository with large number of refs that
+ point to identical commits are optimized by not listing the same commit
+ during the common ancestor negotiation exchange with the other side.
+
+ * Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig)
+ using "git add" will send the contents straight to a packfile without
+ having to hold it and its compressed representation both at the same
+ time in memory.
+
+ * Processes spawned by "[alias] <name> = !process" in the configuration
+ can inspect GIT_PREFIX environment variable to learn where in the
+ working tree the original command was invoked.
+
+ * A magic pathspec ":/" tells a command that limits its operation to
+ the current directory when ran from a subdirectory to work on the
+ entire working tree. In general, ":/path/to/file" would be relative
+ to the root of the working tree hierarchy.
+
+ After "git reset --hard; edit Makefile; cd t/", "git add -u" would
+ be a no-op, but "git add -u :/" would add the updated contents of
+ the Makefile at the top level. If you want to name a path in the
+ current subdirectory whose unusual name begins with ":/", you can
+ name it by "./:/that/path" or by "\:/that/path".
+
+ * "git blame" learned "--abbrev[=<n>]" option to control the minimum
+ number of hexdigits shown for commit object names.
+
+ * "git blame" learned "--line-porcelain" that is less efficient but is
+ easier to parse.
+
+ * Aborting "git commit --interactive" discards updates to the index
+ made during the interactive session.
+
+ * "git commit" learned a "--patch" option to directly jump to the
+ per-hunk selection UI of the interactive mode.
+
+ * "git diff" and its family of commands learned --dirstat=0 to show
+ directories that contribute less than 0.1% of changes.
+
+ * "git diff" and its family of commands learned --dirstat=lines mode to
+ assess damage to the directory based on number of lines in the patch
+ output, not based on the similarity numbers.
+
+ * "git format-patch" learned "--quiet" option to suppress the output of
+ the names of generated files.
+
+ * "git format-patch" quotes people's names when it has RFC822 special
+ characters in it, e.g. "Junio C. Hamano" <jch@example.com>. Earlier
+ it was up to the user to do this when using its output.
+
+ * "git format-patch" can take an empty --subject-prefix now.
+
+ * "git grep" learned the "-P" option to take pcre regular expressions.
+
+ * "git log" and friends learned a new "--notes" option to replace the
+ "--show-notes" option. Unlike "--show-notes", "--notes=<ref>" does
+ not imply showing the default notes.
+
+ * They also learned a log.abbrevCommit configuration variable to augment
+ the --abbrev-commit command line option.
+
+ * "git ls-remote" learned "--exit-code" option to consider it a
+ different kind of error when no remote ref to be shown.
+
+ * "git merge" learned "-" as a short-hand for "the previous branch", just
+ like the way "git checkout -" works.
+
+ * "git merge" uses "merge.ff" configuration variable to decide to always
+ create a merge commit (i.e. --no-ff, aka merge.ff=no), refuse to create
+ a merge commit (i.e. --ff-only, aka merge.ff=only). Setting merge.ff=yes
+ (or not setting it at all) restores the default behaviour of allowing
+ fast-forward to happen when possible.
+
+ * p4-import (from contrib) learned a new option --preserve-user.
+
+ * "git read-tree -m" learned "--dry-run" option that reports if a merge
+ would fail without touching the index nor the working tree.
+
+ * "git rebase" that does not specify on top of which branch to rebase
+ the current branch now uses @{upstream} of the current branch.
+
+ * "git rebase" finished either normally or with --abort did not
+ update the reflog for HEAD to record the event to come back to
+ where it started from.
+
+ * "git remote add -t only-this-branch --mirror=fetch" is now allowed. Earlier
+ a fetch-mode mirror meant mirror everything, but now it only means refs are
+ not renamed.
+
+ * "git rev-list --count" used with "--cherry-mark" counts the cherry-picked
+ commits separately, producing more a useful output.
+
+ * "git submodule update" learned "--force" option to get rid of local
+ changes in submodules and replace them with the up-to-date version.
+
+ * "git status" and friends ignore .gitmodules file while the file is
+ still in a conflicted state during a merge, to avoid using information
+ that is not final and possibly corrupt with conflict markers.
+
+Also contains various documentation updates and minor miscellaneous
+changes.
+
+
+Fixes since v1.7.5
+------------------
+
+Unless otherwise noted, all the fixes in 1.7.5.X maintenance track are
+included in this release.
+
+ * "git config" used to choke with an insanely long line.
+ (merge ef/maint-strbuf-init later)
+
+ * "git diff --quiet" did not work well with --diff-filter.
+ (merge jk/diff-not-so-quick later)
+
+ * "git status -z" did not default to --porcelain output format.
+ (merge bc/maint-status-z-to-use-porcelain later)

+Git v1.7.7.1 Release Notes
+==========================
+
+Fixes since v1.7.7
+------------------
+
+ * On some BSD systems, adding +s bit on directories is detrimental
+ (it is not necessary on BSD to begin with). "git init --shared"
+ has been updated to take this into account without extra makefile
+ settings on platforms the Makefile knows about.
+
+ * After incorrectly written third-party tools store a tag object in
+ HEAD, git diagnosed it as a repository corruption and refused to
+ proceed in order to avoid spreading the damage. We now gracefully
+ recover from such a situation by pretending as if the commit that
+ is pointed at by the tag were in HEAD.
+
+ * "git apply --whitespace=error" did not bother to report the exact
+ line number in the patch that introduced new blank lines at the end
+ of the file.
+
+ * "git apply --index" did not check corrupted patch.
+
+ * "git checkout $tree $directory/" resurrected paths locally removed or
+ modified only in the working tree in $directory/ that did not appear
+ in $directory of the given $tree. They should have been kept intact.
+
+ * "git diff $tree $path" used to apply the pathspec at the output stage,
+ reading the whole tree, wasting resources.
+
+ * The code to check for updated submodules during a "git fetch" of the
+ superproject had an unnecessary quadratic loop.
+
+ * "git fetch" from a large bundle did not enable the progress output.
+
+ * When "git fsck --lost-and-found" found that an empty blob object in the
+ object store is unreachable, it incorrectly reported an error after
+ writing the lost blob out successfully.
+
+ * "git filter-branch" did not refresh the index before checking that the
+ working tree was clean.
+
+ * "git grep $tree" when run with multiple threads had an unsafe access to
+ the object database that should have been protected with mutex.
+
+ * The "--ancestry-path" option to "git log" and friends misbehaved in a
+ history with complex criss-cross merges and showed an uninteresting
+ side history as well.
+
+ * Test t1304 assumed LOGNAME is always set, which may not be true on
+ some systems.
+
+ * Tests with --valgrind failed to find "mergetool" scriptlets.
+
+ * "git patch-id" miscomputed the patch-id in a patch that has a line longer
+ than 1kB.
+
+ * When an "exec" insn failed after modifying the index and/or the working
+ tree during "rebase -i", we now check and warn that the changes need to
+ be cleaned up.

+Git v1.7.7.2 Release Notes
+==========================
+
+Fixes since v1.7.7.1

+
+ * We used to drop error messages from libcurl on certain kinds of
+ errors.
+
+ * Error report from smart HTTP transport, when the connection was
+ broken in the middle of a transfer, showed a useless message on
+ a corrupt packet.
+
+ * "git fetch --prune" was unsafe when used with refspecs from the
+ command line.
+
+ * The attribute mechanism did not use case insensitive match when
+ core.ignorecase was set.
+
+ * "git bisect" did not notice when it failed to update the working tree
+ to the next commit to be tested.
+
+ * "git config --bool --get-regexp" failed to separate the variable name
+ and its value "true" when the variable is defined without "= true".
+
+ * "git remote rename $a $b" were not careful to match the remote name
+ against $a (i.e. source side of the remote nickname).
+
+ * "git mergetool" did not use its arguments as pathspec, but as a path to
+ the file that may not even have any conflict.
+
+ * "git diff --[num]stat" used to use the number of lines of context
+ different from the default, potentially giving different results from
+ "git diff | diffstat" and confusing the users.
+
+ * "git pull" and "git rebase" did not work well even when GIT_WORK_TREE is
+ set correctly with GIT_DIR if the current directory is outside the working
+ tree.
+
+ * "git send-email" did not honor the configured hostname when restarting
+ the HELO/EHLO exchange after switching TLS on.
+
+ * "gitweb" used to produce a non-working link while showing the contents
+ of a blob, when JavaScript actions are enabled.

+
+ * Adjust the "quick-install-doc" procedures as preformatted
+ html/manpage are no longer in the source repository.
+
+ * The logic to optimize the locality of the data in a pack introduced in
+ 1.7.7 was grossly inefficient.
+
+ * The logic to filter out forked projects in the project list in
+ "gitweb" was broken for some time.
+
+ * "git branch -m/-M" advertised to update RENAME_REF ref in the
+ commit log message that introduced the feature but not anywhere in
+ the documentation, and never did update such a ref anyway. This
+ undocumented misfeature that did not exist has been excised.

+Git v1.7.7 Release Notes
+========================
+
+Updates since v1.7.6
+--------------------
+
+ * The scripting part of the codebase is getting prepared for i18n/l10n.
+
+ * Interix, Cygwin and Minix ports got updated.
+
+ * Various updates to git-p4 (in contrib/), fast-import, and git-svn.
+
+ * Gitweb learned to read from /etc/gitweb-common.conf when it exists,
+ before reading from gitweb_config.perl or from /etc/gitweb.conf
+ (this last one is read only when per-repository gitweb_config.perl
+ does not exist).
+
+ * Various codepaths that invoked zlib deflate/inflate assumed that these
+ functions can compress or uncompress more than 4GB data in one call on
+ platforms with 64-bit long, which has been corrected.
+
+ * Git now recognizes loose objects written by other implementations that
+ use a non-standard window size for zlib deflation (e.g. Agit running on
+ Android with 4kb window). We used to reject anything that was not
+ deflated with 32kb window.
+
+ * Interaction between the use of pager and coloring of the output has
+ been improved, especially when a command that is not built-in was
+ involved.
+
+ * "git am" learned to pass the "--exclude=<path>" option through to underlying
+ "git apply".
+
+ * You can now feed many empty lines before feeding an mbox file to
+ "git am".
+
+ * "git archive" can be told to pass the output to gzip compression and
+ produce "archive.tar.gz".
+
+ * "git bisect" can be used in a bare repository (provided that the test
+ you perform per each iteration does not need a working tree, of
+ course).
+
+ * The length of abbreviated object names in "git branch -v" output
+ now honors the core.abbrev configuration variable.
+
+ * "git check-attr" can take relative paths from the command line.
+
+ * "git check-attr" learned an "--all" option to list the attributes for a
+ given path.
+
+ * "git checkout" (both the code to update the files upon checking out a
+ different branch and the code to checkout a specific set of files) learned
+ to stream the data from object store when possible, without having to
+ read the entire contents of a file into memory first. An earlier round
+ of this code that is not in any released version had a large leak but
+ now it has been plugged.
+
+ * "git clone" can now take a "--config key=value" option to set the
+ repository configuration options that affect the initial checkout.
+
+ * "git commit <paths>..." now lets you feed relative pathspecs that
+ refer to outside your current subdirectory.
+
+ * "git diff --stat" learned a --stat-count option to limit the output of
+ a diffstat report.
+
+ * "git diff" learned a "--histogram" option to use a different diff
+ generation machinery stolen from jgit, which might give better
+ performance.
+
+ * "git diff" had a weird worst case behaviour that can be triggered
+ when comparing files with potentially many places that could match.
+
+ * "git fetch", "git push" and friends no longer show connection
+ errors for addresses that couldn't be connected to when at least one
+ address succeeds (this is arguably a regression but a deliberate
+ one).
+
+ * "git grep" learned "--break" and "--heading" options, to let users mimic
+ the output format of "ack".
+
+ * "git grep" learned a "-W" option that shows wider context using the same
+ logic used by "git diff" to determine the hunk header.
+
+ * Invoking the low-level "git http-fetch" without "-a" option (which
+ git itself never did---normal users should not have to worry about
+ this) is now deprecated.
+
+ * The "--decorate" option to "git log" and its family learned to
+ highlight grafted and replaced commits.
+
+ * "git rebase master topci" no longer spews usage hints after giving
+ the "fatal: no such branch: topci" error message.
+
+ * The recursive merge strategy implementation got a fairly large
+ fix for many corner cases that may rarely happen in real world
+ projects (it has been verified that none of the 16000+ merges in
+ the Linux kernel history back to v2.6.12 is affected with the
+ corner case bugs this update fixes).
+
+ * "git stash" learned an "--include-untracked option".
+
+ * "git submodule update" used to stop at the first error updating a
+ submodule; it now goes on to update other submodules that can be
+ updated, and reports the ones with errors at the end.
+
+ * "git push" can be told with the "--recurse-submodules=check" option to
+ refuse pushing of the supermodule, if any of its submodules'
+ commits hasn't been pushed out to their remotes.
+
+ * "git upload-pack" and "git receive-pack" learned to pretend that only a
+ subset of the refs exist in a repository. This may help a site to
+ put many tiny repositories into one repository (this would not be
+ useful for larger repositories as repacking would be problematic).
+
+ * "git verify-pack" has been rewritten to use the "index-pack" machinery
+ that is more efficient in reading objects in packfiles.
+
+ * test scripts for gitweb tried to run even when CGI-related perl modules
+ are not installed; they now exit early when the latter are unavailable.
+
+Also contains various documentation updates and minor miscellaneous
+changes.
+
+
+Fixes since v1.7.6
+------------------
+
+Unless otherwise noted, all fixes in the 1.7.6.X maintenance track are
+included in this release.
+
+ * "git branch -m" and "git checkout -b" incorrectly allowed the tip
+ of the branch that is currently checked out updated.

+Git v1.7.8 Release Notes
+========================
+
+Updates since v1.7.7
+--------------------
+
+ * Some git-svn, git-gui, git-p4 (in contrib) and msysgit updates.
+
+ * Updates to bash completion scripts.
+
+ * The build procedure has been taught to take advantage of computed
+ dependency automatically when the complier supports it.
+
+ * The date parser now accepts timezone designators that lack minutes
+ part and also has a colon between "hh:mm".
+
+ * The contents of the /etc/mailname file, if exists, is used as the
+ default value of the hostname part of the committer/author e-mail.
+
+ * "git am" learned how to read from patches generated by Hg.
+
+ * "git archive" talking with a remote repository can report errors
+ from the remote side in a more informative way.
+
+ * "git branch" learned an explicit --list option to ask for branches
+ listed, optionally with a glob matching pattern to limit its output.
+
+ * "git check-attr" learned "--cached" option to look at .gitattributes
+ files from the index, not from the working tree.
+
+ * Variants of "git cherry-pick" and "git revert" that take multiple
+ commits learned to "--continue" and "--abort".
+
+ * "git daemon" gives more human readble error messages to clients
+ using ERR packets when appropriate.
+
+ * Errors at the network layer is logged by "git daemon".
+
+ * "git diff" learned "--minimal" option to spend extra cycles to come
+ up with a minimal patch output.
+
+ * "git diff" learned "--function-context" option to show the whole
+ function as context that was affected by a change.
+
+ * "git difftool" can be told to skip launching the tool for a path by
+ answering 'n' to its prompt.
+
+ * "git fetch" learned to honor transfer.fsckobjects configuration to
+ validate the objects that were received from the other end, just like
+ "git receive-pack" (the receiving end of "git push") does.
+
+ * "git fetch" makes sure that the set of objects it received from the
+ other end actually completes the history before updating the refs.
+ "git receive-pack" (the receiving end of "git push") learned to do the
+ same.
+
+ * "git fetch" learned that fetching/cloning from a regular file on the
+ filesystem is not necessarily a request to unpack a bundle file; the
+ file could be ".git" with "gitdir: <path>" in it.
+
+ * "git for-each-ref" learned "%(contents:subject)", "%(contents:body)"
+ and "%(contents:signature)". The last one is useful for signed tags.
+
+ * "git grep" used to incorrectly pay attention to .gitignore files
+ scattered in the directory it was working in even when "--no-index"
+ option was used. It no longer does this. The "--exclude-standard"
+ option needs to be given to explicitly activate the ignore
+ mechanism.
+
+ * "git grep" learned "--untracked" option, where given patterns are
+ searched in untracked (but not ignored) files as well as tracked
+ files in the working tree, so that matches in new but not yet
+ added files do not get missed.
+
+ * The recursive merge backend no longer looks for meaningless
+ existing merges in submodules unless in the outermost merge.
+
+ * "git log" and friends learned "--children" option.
+
+ * "git ls-remote" learned to respond to "-h"(elp) requests.
+
+ * "mediawiki" remote helper can interact with (surprise!) MediaWiki
+ with "git fetch" & "git push".
+
+ * "git merge" learned the "--edit" option to allow users to edit the
+ merge commit log message.
+
+ * "git rebase -i" can be told to use special purpose editor suitable
+ only for its insn sheet via sequence.editor configuration variable.
+
+ * "git send-email" learned to respond to "-h"(elp) requests.
+
+ * "git send-email" allows the value given to sendemail.aliasfile to begin
+ with "~/" to refer to the $HOME directory.
+
+ * "git send-email" forces use of Authen::SASL::Perl to work around
+ issues between Authen::SASL::Cyrus and AUTH PLAIN/LOGIN.
+
+ * "git stash" learned "--include-untracked" option to stash away
+ untracked/ignored cruft from the working tree.
+
+ * "git submodule clone" does not leak an error message to the UI
+ level unnecessarily anymore.
+
+ * "git submodule update" learned to honor "none" as the value for
+ submodule.<name>.update to specify that the named submodule should
+ not be checked out by default.
+
+ * When populating a new submodule directory with "git submodule init",
+ the $GIT_DIR metainformation directory for submodules is created inside
+ $GIT_DIR/modules/<name>/ directory of the superproject and referenced
+ via the gitfile mechanism. This is to make it possible to switch
+ between commits in the superproject that has and does not have the
+ submodule in the tree without re-cloning.
+
+ * "gitweb" leaked unescaped control characters from syntax hiliter
+ outputs.
+
+ * "gitweb" can be told to give custom string at the end of the HTML
+ HEAD element.
+
+ * "gitweb" now has its own manual pages.
+
+
+Also contains other documentation updates and minor code cleanups.
+
+
+Fixes since v1.7.7
+------------------
+
+Unless otherwise noted, all fixes in the 1.7.7.X maintenance track are
+included in this release.
+
+ * HTTP transport did not use pushurl correctly, and also did not tell
+ what host it is trying to authenticate with when asking for
+ credentials.
+ (merge deba493 jk/http-auth later to maint).
+
+ * "git blame" was aborted if started from an uncommitted content and
+ the path had the textconv filter in effect.
+ (merge 8518088 ss/blame-textconv-fake-working-tree later to maint).
+
+ * Adding many refs to the local repository in one go (e.g. "git fetch"
+ that fetches many tags) and looking up a ref by name in a repository
+ with too many refs were unnecessarily slow.
+ (merge 17d68a54d jp/get-ref-dir-unsorted later to maint).
+
+ * Report from "git commit" on untracked files was confused under
+ core.ignorecase option.
+ (merge 395c7356 jk/name-hash-dirent later to maint).
+
+ * "git merge" did not understand ":/<pattern>" as a way to name a commit.
+
+ " "git push" on the receiving end used to call post-receive and post-update
+ hooks for attempted removal of non-existing refs.

+-------------------------
-(A Large Angry SCM)
-
-By default, Thunderbird will both wrap emails as well as flag them as
-being 'format=flowed', both of which will make the resulting email unusable
-by git.
-
-Here are some hints on how to successfully submit patches inline using
-Thunderbird.
-
-There are two different approaches. One approach is to configure
-Thunderbird to not mangle patches. The second approach is to use
-an external editor to keep Thunderbird from mangling the patches.
-
-Approach #1 (configuration):
-
-This recipe is current as of Thunderbird 2.0.0.19. Three steps:
- 1. Configure your mail server composition as plain text
- Edit...Account Settings...Composition & Addressing,
- uncheck 'Compose Messages in HTML'.
- 2. Configure your general composition window to not wrap
- Edit..Preferences..Composition, wrap plain text messages at 0
- 3. Disable the use of format=flowed
- Edit..Preferences..Advanced..Config Editor. Search for:
- mailnews.send_plaintext_flowed
- toggle it to make sure it is set to 'false'.
-
-After that is done, you should be able to compose email as you
-otherwise would (cut + paste, git-format-patch | git-imap-send, etc),
-and the patches should not be mangled.
-
-Approach #2 (external editor):
-
-This recipe appears to work with the current [*1*] Thunderbird from Suse.
-
-The following Thunderbird extensions are needed:
- AboutConfig 0.5
- http://aboutconfig.mozdev.org/
- External Editor 0.7.2
- http://globs.org/articles.php?lng=en&pg=8
-
-1) Prepare the patch as a text file using your method of choice.
-
-2) Before opening a compose window, use Edit->Account Settings to
-uncheck the "Compose messages in HTML format" setting in the
-"Composition & Addressing" panel of the account to be used to send the
-patch. [*2*]
-
-3) In the main Thunderbird window, _before_ you open the compose window
-for the patch, use Tools->about:config to set the following to the
-indicated values:
- mailnews.send_plaintext_flowed => false
- mailnews.wraplength => 0
-
-4) Open a compose window and click the external editor icon.
-
-5) In the external editor window, read in the patch file and exit the
-editor normally.
-
-6) Back in the compose window: Add whatever other text you wish to the
-message, complete the addressing and subject fields, and press send.
-
-7) Optionally, undo the about:config/account settings changes made in
-steps 2 & 3.
-
-
-[Footnotes]
-*1* Version 1.0 (20041207) from the MozillaThunderbird-1.0-5 rpm of Suse
-9.3 professional updates.
-
-*2* It may be possible to do this with about:config and the following
-settings but I haven't tried, yet.
- mail.html_compose => false
- mail.identity.default.compose_html => false
- mail.identity.id?.compose_html => false
-
-(Lukas Sandström)

-There is a script in contrib/thunderbird-patch-inline which can help
-you include patches with Thunderbird in an easy way. To use it, do the
-steps above and then use the script as the external editor.

------
-
-This should help you to submit patches inline using KMail.
-
-1) Prepare the patch as a text file.
-
-2) Click on New Mail.
-
-3) Go under "Options" in the Composer window and be sure that

-Gmail
------
-
-GMail does not appear to have any way to turn off line wrapping in the web
-interface, so this will mangle any emails that you send. You can however
-use any IMAP email client to connect to the google imap server, and forward
-the emails through that. Just make sure to disable line wrapping in that
-email client. Alternatively, use "git send-email" instead.
-
-Submitting properly formatted patches via Gmail is simple now that
-IMAP support is available. First, edit your ~/.gitconfig to specify your
-account settings:
-
-[imap]
- folder = "[Gmail]/Drafts"
- host = imaps://imap.gmail.com
- user = user@gmail.com
- pass = p4ssw0rd
- port = 993
- sslverify = false
-
-You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error
-that the "Folder doesn't exist".
-
-Next, ensure that your Gmail settings are correct. In "Settings" the
-"Use Unicode (UTF-8) encoding for outgoing messages" should be checked.
-
-Once your commits are ready to send to the mailing list, run the following
-command to send the patch emails to your Gmail Drafts folder.
-
- $ git format-patch -M --stdout origin/master | git imap-send
-
-Go to your Gmail account, open the Drafts folder, find the patch email, fill
-in the To: and CC: fields and send away!

+EDITING PATCHES
+---------------
+
+Invoking `git add -e` or selecting `e` from the interactive hunk
+selector will open a patch in your editor; after the editor exits, the
+result is applied to the index. You are free to make arbitrary changes
+to the patch, but note that some changes may have confusing results, or
+even result in a patch that cannot be applied. If you want to abort the
+operation entirely (i.e., stage nothing new in the index), simply delete
+all lines of the patch. The list below describes some common things you
+may see in a patch, and which editing operations make sense on them.
+
+--
+added content::
+
+Added content is represented by lines beginning with "{plus}". You can
+prevent staging any addition lines by deleting them.
+
+removed content::
+
+Removed content is represented by lines beginning with "-". You can
+prevent staging their removal by converting the "-" to a " " (space).
+
+modified content::
+
+Modified content is represented by "-" lines (removing the old content)
+followed by "{plus}" lines (adding the replacement content). You can
+prevent staging the modification by converting "-" lines to " ", and
+removing "{plus}" lines. Beware that modifying only half of the pair is
+likely to introduce confusing changes to the index.
+--
+
+There are also more complex operations that can be performed. But beware
+that because the patch is applied only to the index and not the working
+tree, the working tree will appear to "undo" the change in the index.
+For example, introducing a new line into the index that is in neither
+the HEAD nor the working tree will stage the new line for commit, but
+the line will appear to be reverted in the working tree.
+
+Avoid using these constructs, or do so with extreme caution.
+
+--
+removing untouched content::
+
+Content which does not differ between the index and working tree may be
+shown on context lines, beginning with a " " (space). You can stage
+context lines for removal by converting the space to a "-". The
+resulting working tree file will appear to re-add the content.
+
+modifying existing content::
+
+One can also modify context lines by staging them for removal (by
+converting " " to "-") and adding a "{plus}" line with the new content.
+Similarly, one can modify "{plus}" lines for existing additions or
+modifications. In all cases, the new modification will appear reverted
+in the working tree.
+
+new content::
+
+You may also add new content that does not exist in the patch; simply
+add new lines, each starting with "{plus}". The addition will appear
+reverted in the working tree.
+--
+
+There are also several operations which should be avoided entirely, as
+they will make the patch impossible to apply:
+
+* adding context (" ") or removal ("-") lines
+* deleting context or removal lines
+* modifying the contents of context or removal lines

A reference is used in git to specify branches and tags. A

-imposes the following rules on how references are named:

. They can include slash `/` for hierarchical (directory)
grouping, but no slash-separated component can begin with a

-It is sometimes useful to be able to 'checkout' a commit that is

-example is to check out the commit at a tagged official release

+HEAD normally refers to a named branch (e.g. 'master'). Meanwhile, each
+branch refers to a specific commit. Let's look at a repo with three
+commits, one of them tagged, and with branch 'master' checked out:
------------
-$ git checkout v2.6.18
+ HEAD (refers to branch 'master')
+ |
+ v
+a---b---c branch 'master' (refers to commit 'c')

------------
-Earlier versions of git did not allow this and asked you to
-create a temporary branch using the `-b` option, but starting from
-version 1.5.0, the above command 'detaches' your HEAD from the
-current branch and directly points at the commit named by the tag
-(`v2.6.18` in the example above).
-
-You can use all git commands while in this state. You can use
-`git reset --hard $othercommit` to further move around, for
-example. You can make changes and create a new commit on top of
-a detached HEAD. You can even create a merge by using `git
-merge $othercommit`.
-
-The state you are in while your HEAD is detached is not recorded
-by any branch (which is natural --- you are not on any branch).
-What this means is that you can discard your temporary commits
-and merges by switching back to an existing branch (e.g. `git
-checkout master`), and a later `git prune` or `git gc` would
-garbage-collect them. If you did this by mistake, you can ask
-the reflog for HEAD where you were, e.g.
+When a commit is created in this state, the branch is updated to refer to
+the new commit. Specifically, 'git commit' creates a new commit 'd', whose
+parent is commit 'c', and then updates branch 'master' to refer to new
+commit 'd'. HEAD still refers to branch 'master' and so indirectly now refers
+to commit 'd':
------------
+$ edit; git add; git commit
+
+ HEAD (refers to branch 'master')
+ |
+ v
+a---b---c---d branch 'master' (refers to commit 'd')
+ ^
+ |
+ tag 'v2.0' (refers to commit 'b')
+------------
+
+It is sometimes useful to be able to checkout a commit that is not at
+the tip of any named branch, or even to create a new commit that is not
+referenced by a named branch. Let's look at what happens when we
+checkout commit 'b' (here we show two ways this may be done):
+
+------------
+$ git checkout v2.0 # or
+$ git checkout master^^
+
+ HEAD (refers to commit 'b')
+ |
+ v
+a---b---c---d branch 'master' (refers to commit 'd')
+ ^
+ |
+ tag 'v2.0' (refers to commit 'b')
+------------
+
+Notice that regardless of which checkout command we use, HEAD now refers
+directly to commit 'b'. This is known as being in detached HEAD state.
+It means simply that HEAD refers to a specific commit, as opposed to
+referring to a named branch. Let's see what happens when we create a commit:
+
+------------
+$ edit; git add; git commit
+
+ HEAD (refers to commit 'e')
+ |
+ v
+ e
+ /
+a---b---c---d branch 'master' (refers to commit 'd')
+ ^
+ |
+ tag 'v2.0' (refers to commit 'b')
+------------
+
+There is now a new commit 'e', but it is referenced only by HEAD. We can
+of course add yet another commit in this state:
+
+------------
+$ edit; git add; git commit
+
+ HEAD (refers to commit 'f')
+ |
+ v
+ e---f
+ /
+a---b---c---d branch 'master' (refers to commit 'd')
+ ^
+ |
+ tag 'v2.0' (refers to commit 'b')
+------------
+
+In fact, we can perform all the normal git operations. But, let's look
+at what happens when we then checkout master:
+
+------------
+$ git checkout master
+
+ HEAD (refers to branch 'master')
+ e---f |
+ / v
+a---b---c---d branch 'master' (refers to commit 'd')
+ ^
+ |
+ tag 'v2.0' (refers to commit 'b')
+------------
+
+It is important to realize that at this point nothing refers to commit
+'f'. Eventually commit 'f' (and by extension commit 'e') will be deleted
+by the routine git garbage collection process, unless we create a reference
+before that happens. If we have not yet moved away from commit 'f',
+any of these will create a reference to it:
+
+------------
+$ git checkout -b foo <1>
+$ git branch foo <2>
+$ git tag foo <3>
+------------
+
+<1> creates a new branch 'foo', which refers to commit 'f', and then
+updates HEAD to refer to branch 'foo'. In other words, we'll no longer
+be in detached HEAD state after this command.
+
+<2> similarly creates a new branch 'foo', which refers to commit 'f',
+but leaves HEAD detached.
+
+<3> creates a new tag 'foo', which refers to commit 'f',
+leaving HEAD detached.
+
+If we have moved away from commit 'f', then we must first recover its object
+name (typically by using git reflog), and then we can create a reference to
+it. For example, to see the last two commits to which HEAD referred, we
+can use either of these commands:
+
+------------
+$ git reflog -2 HEAD # or
$ git log -g -2 HEAD

DESCRIPTION
-----------
-Given one existing commit, apply the change the patch introduces, and record a
-new commit that records it. This requires your working tree to be clean (no
-modifications from the HEAD commit).
+
+Given one or more existing commits, apply the change each one
+introduces, recording a new commit for each. This requires your
+working tree to be clean (no modifications from the HEAD commit).
+
+When it is not obvious how to apply a change, the following
+happens:
+
+1. The current branch and `HEAD` pointer stay at the last commit
+ successfully made.
+2. The `CHERRY_PICK_HEAD` ref is set to point at the commit that
+ introduced the change that is difficult to apply.
+3. Paths in which the change applied cleanly are updated both
+ in the index file and in your working tree.
+4. For conflicting paths, the index file records up to three
+ versions, as described in the "TRUE MERGE" section of
+ linkgit:git-merge[1]. The working tree files will include
+ a description of the conflict bracketed by the usual
+ conflict markers `<<<<<<<` and `>>>>>>>`.
+5. No other modifications are made.
+
+See linkgit:git-merge[1] for some hints on resolving such
+conflicts.

+
+EXAMPLES
+--------
+`git cherry-pick master`::
+
+ Apply the change introduced by the commit at the tip of the
+ master branch and create a new commit with this change.
+
+`git cherry-pick ..master`::
+`git cherry-pick ^HEAD master`::
+
+ Apply the changes introduced by all commits that are ancestors
+ of master but not of HEAD to produce new commits.
+
+`git cherry-pick master{tilde}4 master{tilde}2`::
+
+ Apply the changes introduced by the fifth and third last
+ commits pointed to by master and create 2 new commits with
+ these changes.
+
+`git cherry-pick -n master~1 next`::
+
+ Apply to the working tree and the index the changes introduced
+ by the second last commit pointed to by master and by the last
+ commit pointed to by next, but do not create any commit with
+ these changes.
+
+`git cherry-pick --ff ..next`::
+
+ If history is linear and HEAD is an ancestor of next, update
+ the working tree and advance the HEAD pointer to match next.
+ Otherwise, apply the changes introduced by those commits that
+ are in next but not HEAD to the current branch, creating a new
+ commit for each new change.
+
+`git rev-list --reverse master \-- README | git cherry-pick -n --stdin`::
+
+ Apply the changes introduced by all commits on the master
+ branch that touched README to the working tree and index,
+ so the result can be inspected and made into a single new
+ commit if suitable.
+
+The following sequence attempts to backport a patch, bails out because
+the code the patch applies to has changed too much, and then tries
+again, this time exercising more care about matching up context lines.
+
+------------
+$ git cherry-pick topic^ <1>
+$ git diff <2>
+$ git reset --merge ORIG_HEAD <3>
+$ git cherry-pick -Xpatience topic^ <4>
+------------
+<1> apply the change that would be shown by `git show topic^`.
+In this example, the patch does not apply cleanly, so
+information about the conflict is written to the index and
+working tree and no new commit results.
+<2> summarize changes to be reconciled
+<3> cancel the cherry-pick. In other words, return to the
+pre-cherry-pick state, preserving any local modifications you had in
+the working tree.
+<4> try to apply the change introduced by `topic^` again,
+spending extra time to avoid mistakes based on incorrectly matching
+context lines.

+just fetched commits of the superproject the submodule itself can not be
+fetched, making it impossible to check out that submodule later without
+having to do a fetch again. This is expected to be fixed in a future git

+
+When sending a patch this way, most often you are sending your own
+patch, so in addition to the "`From $SHA1 $magic_timestamp`" marker you
+should omit `From:` and `Date:` lines from the patch file. The patch
+title is likely to be different from the subject of the discussion the
+patch is in response to, so it is likely that you would want to keep
+the Subject: line, like the example above.
+
+Checking for patch corruption
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Many mailers if not set up properly will corrupt whitespace. Here are
+two common types of corruption:
+
+* Empty context lines that do not have _any_ whitespace.
+
+* Non-empty context lines that have one extra whitespace at the
+ beginning.
+
+One way to test if your MUA is set up correctly is:
+
+* Send the patch to yourself, exactly the way you would, except
+ with To: and Cc: lines that do not contain the list and
+ maintainer address.
+
+* Save that patch to a file in UNIX mailbox format. Call it a.patch,
+ say.
+
+* Apply it:
+
+ $ git fetch <project> master:test-apply
+ $ git checkout test-apply
+ $ git reset --hard
+ $ git am a.patch
+
+If it does not apply correctly, there can be various reasons.
+
+* The patch itself does not apply cleanly. That is _bad_ but
+ does not have much to do with your MUA. You might want to rebase
+ the patch with linkgit:git-rebase[1] before regenerating it in
+ this case.
+
+* The MUA corrupted your patch; "am" would complain that
+ the patch does not apply. Look in the .git/rebase-apply/ subdirectory and
+ see what 'patch' file contains and check for the common
+ corruption patterns mentioned above.
+
+* While at it, check the 'info' and 'final-commit' files as well.
+ If what is in 'final-commit' is not exactly what you would want to
+ see in the commit log message, it is very likely that the
+ receiver would end up hand editing the log message when applying
+ your patch. Things like "Hi, this is my first patch.\n" in the
+ patch e-mail should come after the three-dash line that signals
+ the end of the commit message.
+
+MUA-SPECIFIC HINTS
+------------------
+Here are some hints on how to successfully submit patches inline using
+various mailers.
+
+GMail
+~~~~~
+GMail does not have any way to turn off line wrapping in the web
+interface, so it will mangle any emails that you send. You can however
+use "git send-email" and send your patches through the GMail SMTP server, or
+use any IMAP email client to connect to the google IMAP server and forward
+the emails through that.
+
+For hints on using 'git send-email' to send your patches through the
+GMail SMTP server, see the EXAMPLE section of linkgit:git-send-email[1].
+
+For hints on submission using the IMAP interface, see the EXAMPLE
+section of linkgit:git-imap-send[1].
+
+Thunderbird
+~~~~~~~~~~~
+By default, Thunderbird will both wrap emails as well as flag
+them as being 'format=flowed', both of which will make the
+resulting email unusable by git.
+
+There are three different approaches: use an add-on to turn off line wraps,
+configure Thunderbird to not mangle patches, or use
+an external editor to keep Thunderbird from mangling the patches.
+
+Approach #1 (add-on)
+^^^^^^^^^^^^^^^^^^^^
+
+Install the Toggle Word Wrap add-on that is available from
+https://addons.mozilla.org/thunderbird/addon/toggle-word-wrap/
+It adds a menu entry "Enable Word Wrap" in the composer's "Options" menu
+that you can tick off. Now you can compose the message as you otherwise do
+(cut + paste, 'git format-patch' | 'git imap-send', etc), but you have to
+insert line breaks manually in any text that you type.
+
+Approach #2 (configuration)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Three steps:
+
+1. Configure your mail server composition as plain text:
+ Edit...Account Settings...Composition & Addressing,
+ uncheck "Compose Messages in HTML".
+
+2. Configure your general composition window to not wrap.
++
+In Thunderbird 2:
+Edit..Preferences..Composition, wrap plain text messages at 0
++
+In Thunderbird 3:
+Edit..Preferences..Advanced..Config Editor. Search for
+"mail.wrap_long_lines".
+Toggle it to make sure it is set to `false`.
+
+3. Disable the use of format=flowed:
+Edit..Preferences..Advanced..Config Editor. Search for
+"mailnews.send_plaintext_flowed".
+Toggle it to make sure it is set to `false`.
+
+After that is done, you should be able to compose email as you
+otherwise would (cut + paste, 'git format-patch' | 'git imap-send', etc),
+and the patches will not be mangled.
+
+Approach #3 (external editor)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following Thunderbird extensions are needed:
+AboutConfig from http://aboutconfig.mozdev.org/ and
+External Editor from http://globs.org/articles.php?lng=en&pg=8
+
+1. Prepare the patch as a text file using your method of choice.
+
+2. Before opening a compose window, use Edit->Account Settings to
+ uncheck the "Compose messages in HTML format" setting in the
+ "Composition & Addressing" panel of the account to be used to
+ send the patch.
+
+3. In the main Thunderbird window, 'before' you open the compose
+ window for the patch, use Tools->about:config to set the
+ following to the indicated values:
++
+----------
+ mailnews.send_plaintext_flowed => false
+ mailnews.wraplength => 0
+----------
+
+4. Open a compose window and click the external editor icon.
+
+5. In the external editor window, read in the patch file and exit
+ the editor normally.
+
+Side note: it may be possible to do step 2 with
+about:config and the following settings but no one's tried yet.
+
+----------
+ mail.html_compose => false
+ mail.identity.default.compose_html => false
+ mail.identity.id?.compose_html => false
+----------
+
+There is a script in contrib/thunderbird-patch-inline which can help
+you include patches with Thunderbird in an easy way. To use it, do the
+steps above and then use the script as the external editor.
+
+KMail
+~~~~~
+This should help you to submit patches inline using KMail.
+
+1. Prepare the patch as a text file.
+
+2. Click on New Mail.
+
+3. Go under "Options" in the Composer window and be sure that
+ "Word wrap" is not set.
+
+4. Use Message -> Insert file... and insert the patch.
+
+5. Back in the compose window: add whatever other text you wish to the
+ message, complete the addressing and subject fields, and press send.

-CONFIGURATION

+good shape and committed locally, so it will not be clobbered if
+there are conflicts. See also linkgit:git-stash[1].
+'git pull' and 'git merge' will stop without doing anything when

-branch.<name>.mergeoptions::
- Sets default options for merging into branch <name>. The syntax and
- supported options are the same as those of 'git merge', but option
- values containing whitespace characters are currently not supported.
+To avoid recording unrelated changes in the merge commit,
+'git pull' and 'git merge' will also abort if there are any changes
+registered in the index relative to the `HEAD` commit. (One
+exception is when the changed index entries are in the state that
+would result from the merge already.)
-HOW MERGE WORKS
----------------
+If all named commits are already ancestors of `HEAD`, 'git merge'
+will exit early with the message "Already up-to-date."
-A merge is always between the current `HEAD` and one or more
-commits (usually, branch head or tag), and the index file must
-match the tree of `HEAD` commit (i.e. the contents of the last commit)
-when it starts out. In other words, `git diff --cached HEAD` must
-report no changes. (One exception is when the changed index
-entries are already in the same state that would result from
-the merge anyway.)
+FAST-FORWARD MERGE
+------------------
-Three kinds of merge can happen:
+Often the current branch head is an ancestor of the named commit.
+This is the most common case especially when invoked from 'git
+pull': you are tracking an upstream repository, you have committed
+no local changes, and now you want to update to a newer upstream
+revision. In this case, a new commit is not needed to store the
+combined history; instead, the `HEAD` (along with the index) is
+updated to point at the named commit, without creating an extra
+merge commit.
-* The merged commit is already contained in `HEAD`. This is the
- simplest case, called "Already up-to-date."
+This behavior can be suppressed with the `--no-ff` option.
-* `HEAD` is already contained in the merged commit. This is the
- most common case especially when invoked from 'git pull':
- you are tracking an upstream repository, have committed no local
- changes and now you want to update to a newer upstream revision.
- Your `HEAD` (and the index) is updated to point at the merged
- commit, without creating an extra merge commit. This is
- called "Fast-forward".
+TRUE MERGE
+----------
-* Both the merged commit and `HEAD` are independent and must be
- tied together by a merge commit that has both of them as its parents.
- The rest of this section describes this "True merge" case.
+Except in a fast-forward merge (see above), the branches to be
+merged must be tied together by a merge commit that has both of them
+as its parents.
-The chosen merge strategy merges the two commits into a single
-new source tree.
-When things merge cleanly, this is what happens:
+A merged version reconciling the changes from all branches to be
+merged is committed, and your `HEAD`, index, and working tree are
+updated to it. It is possible to have modifications in the working
+tree as long as they do not overlap; the update will preserve them.
-1. The results are updated both in the index file and in your
- working tree;
-2. Index file is written out as a tree;
-3. The tree gets committed; and
-4. The `HEAD` pointer gets advanced.
+When it is not obvious how to reconcile the changes, the following
+happens:
-Because of 2., we require that the original state of the index
-file matches exactly the current `HEAD` commit; otherwise we
-will write out your local changes already registered in your
-index file along with the merge result, which is not good.
-Because 1. involves only those paths differing between your
-branch and the remote branch you are pulling from during the
-merge (which is typically a fraction of the whole tree), you can
-have local modifications in your working tree as long as they do
-not overlap with what the merge updates.
-
-When there are conflicts, the following happens:
-
-1. `HEAD` stays the same.
-
-2. Cleanly merged paths are updated both in the index file and
+1. The `HEAD` pointer stays the same.
+2. The `MERGE_HEAD` ref is set to point to the other branch head.
+3. Paths that merged cleanly are updated both in the index file and
in your working tree.
-
-3. For conflicting paths, the index file records up to three
- versions; stage1 stores the version from the common ancestor,
- stage2 from `HEAD`, and stage3 from the remote branch (you

tree files contain the result of the "merge" program; i.e. 3-way

DESCRIPTION
-----------
-This command allows you to add notes to commit messages, without
-changing the commit. To discern these notes from the message stored
-in the commit object, the notes are indented like the message, after
-an unindented line saying "Notes:".
+Adds, removes, or reads notes attached to objects, without touching
+the objects themselves.
-To disable commit notes, you have to set the config variable
-core.notesRef to the empty string. Alternatively, you can set it
-to a different ref, something like "refs/notes/bugzilla". This setting
-can be overridden by the environment variable "GIT_NOTES_REF".
+By default, notes are saved to and read from `refs/notes/commits`, but
+this default can be overridden. See the OPTIONS, CONFIGURATION, and
+ENVIRONMENT sections below. If this ref does not exist, it will be
+quietly created when it is first needed to store a note.
+
+A typical use of notes is to supplement a commit message without
+changing the commit itself. Notes can be shown by 'git log' along with
+the original commit message. To distinguish these notes from the
+message stored in the commit object, the notes are indented like the
+message, after an unindented line saying "Notes (<refname>):" (or
+"Notes:" for `refs/notes/commits`).
+
+To change which notes are shown by 'git log', see the
+"notes.displayRef" configuration in linkgit:git-log[1].
+
+See the "notes.rewrite.<command>" configuration for a way to carry
+notes across commands that rewrite commits.
SUBCOMMANDS
-----------
+list::
+ List the notes object for a given object. If no object is
+ given, show a list of all note objects and the objects they
+ annotate (in the format "<note object> <annotated object>").
+ This is the default subcommand if no subcommand is given.
+
+add::
+ Add notes for a given object (defaults to HEAD). Abort if the
+ object already has notes (use `-f` to overwrite existing notes).
+ However, if you're using `add` interactively (using an editor
+ to supply the notes contents), then - instead of aborting -
+ the existing notes will be opened in the editor (like the `edit`
+ subcommand).
+
+copy::
+ Copy the notes for the first object onto the second object.
+ Abort if the second object already has notes, or if the first
+ object has none (use -f to overwrite existing notes to the
+ second object). This subcommand is equivalent to:
+ `git notes add [-f] -C $(git notes list <from-object>) <to-object>`
++
+In `\--stdin` mode, take lines in the format
++
+----------
+<from-object> SP <to-object> [ SP <rest> ] LF
+----------
++
+on standard input, and copy the notes from each <from-object> to its
+corresponding <to-object>. (The optional `<rest>` is ignored so that
+the command can read the input given to the `post-rewrite` hook.)
+
+append::
+ Append to the notes of an existing object (defaults to HEAD).
+ Creates a new notes object if needed.
+
edit::
- Edit the notes for a given commit (defaults to HEAD).
+ Edit the notes for a given object (defaults to HEAD).
show::
- Show the notes for a given commit (defaults to HEAD).
+ Show the notes for a given object (defaults to HEAD).
+merge::
+ Merge the given notes ref into the current notes ref.
+ This will try to merge the changes made by the given
+ notes ref (called "remote") since the merge-base (if
+ any) into the current notes ref (called "local").
++
+If conflicts arise and a strategy for automatically resolving
+conflicting notes (see the -s/--strategy option) is not given,
+the "manual" resolver is used. This resolver checks out the
+conflicting notes in a special worktree (`.git/NOTES_MERGE_WORKTREE`),
+and instructs the user to manually resolve the conflicts there.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
+remove::
+ Remove the notes for given objects (defaults to HEAD). When
+ giving zero or one object from the command line, this is
+ equivalent to specifying an empty note message to
+ the `edit` subcommand.
+
+prune::
+ Remove all notes for non-existing/unreachable objects.
+
+get-ref::
+ Print the current notes ref. This provides an easy way to
+ retrieve the current notes ref (e.g. from scripts).

+
+
+DISCUSSION
+----------
+
+Commit notes are blobs containing extra information about an object
+(usually information to supplement a commit's message). These blobs
+are taken from notes refs. A notes ref is usually a branch which
+contains "files" whose paths are the object names for the objects
+they describe, with some directory separators included for performance
+reasons footnote:[Permitted pathnames have the form
+'ab'`/`'cd'`/`'ef'`/`'...'`/`'abcdef...': a sequence of directory
+names of two hexadecimal digits each followed by a filename with the
+rest of the object ID.].
+
+Every notes change creates a new commit at the specified notes ref.
+You can therefore inspect the history of the notes by invoking, e.g.,
+`git log -p notes/commits`. Currently the commit message only records
+which operation triggered the update, and the commit authorship is
+determined according to the usual rules (see linkgit:git-commit[1]).
+These details may change in the future.
+
+It is also permitted for a notes ref to point directly to a tree
+object, in which case the history of the notes can be read with
+`git log -p -g <refname>`.

+NOTES MERGE STRATEGIES
+----------------------
+
+The default notes merge strategy is "manual", which checks out
+conflicting notes in a special work tree for resolving notes conflicts
+(`.git/NOTES_MERGE_WORKTREE`), and instructs the user to resolve the
+conflicts in that work tree.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
+"ours" automatically resolves conflicting notes in favor of the local
+version (i.e. the current notes ref).
+
+"theirs" automatically resolves notes conflicts in favor of the remote
+version (i.e. the given notes ref being merged into the current notes
+ref).
+
+"union" automatically resolves notes conflicts by concatenating the
+local and remote versions.
+
+"cat_sort_uniq" is similar to "union", but in addition to concatenating
+the local and remote versions, this strategy also sorts the resulting
+lines, and removes duplicate lines from the result. This is equivalent
+to applying the "cat | sort | uniq" shell pipeline to the local and
+remote versions. This strategy is useful if the notes follow a line-based
+format where one wants to avoid duplicated lines in the merge result.
+Note that if either the local or remote version contain duplicate lines
+prior to the merge, these will also be removed by this notes merge
+strategy.
+
+
+EXAMPLES
+--------
+
+You can use notes to add annotations with information that was not
+available at the time a commit was written.
+
+------------
+$ git notes add -m 'Tested-by: Johannes Sixt <j6t@kdbg.org>' 72a144e2
+$ git show -s 72a144e
+[...]

+
+Notes:
+ Tested-by: Johannes Sixt <j6t@kdbg.org>
+------------
+
+In principle, a note is a regular Git blob, and any kind of
+(non-)format is accepted. You can binary-safely create notes from
+arbitrary files using 'git hash-object':
+
+------------
+$ cc *.c
+$ blob=$(git hash-object -w a.out)
+$ git notes --ref=built add -C "$blob" HEAD
+------------
+
+(You cannot simply use `git notes --ref=built add -F a.out HEAD`
+because that is not binary-safe.)
+Of course, it doesn't make much sense to display non-text-format notes
+with 'git log', so if you use such notes, you'll probably need to write
+some special-purpose tools to do something useful with them.
+
+
+CONFIGURATION
+-------------
+
+core.notesRef::
+ Notes ref to read and manipulate instead of
+ `refs/notes/commits`. Must be an unabbreviated ref name.
+ This setting can be overridden through the environment and
+ command line.
+
+notes.displayRef::
+ Which ref (or refs, if a glob or specified more than once), in
+ addition to the default set by `core.notesRef` or
+ 'GIT_NOTES_REF', to read notes from when showing commit
+ messages with the 'git log' family of commands.
+ This setting can be overridden on the command line or by the
+ 'GIT_NOTES_DISPLAY_REF' environment variable.
+ See linkgit:git-log[1].
+
+notes.rewrite.<command>::
+ When rewriting commits with <command> (currently `amend` or
+ `rebase`), if this variable is `false`, git will not copy
+ notes from the original to the rewritten commit. Defaults to
+ `true`. See also "`notes.rewriteRef`" below.
++
+This setting can be overridden by the 'GIT_NOTES_REWRITE_REF'
+environment variable.
+
+notes.rewriteMode::
+ When copying notes during a rewrite, what to do if the target
+ commit already has a note. Must be one of `overwrite`,
+ `concatenate`, and `ignore`. Defaults to `concatenate`.
++
+This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
+environment variable.
+
+notes.rewriteRef::
+ When copying notes during a rewrite, specifies the (fully
+ qualified) ref whose notes should be copied. May be a glob,
+ in which case notes in all matching refs will be copied. You
+ may also specify this configuration several times.
++
+Does not have a default value; you must configure this variable to
+enable note rewriting.
++
+Can be overridden with the 'GIT_NOTES_REWRITE_REF' environment variable.
+
+
+ENVIRONMENT
+-----------
+
+'GIT_NOTES_REF'::
+ Which ref to manipulate notes from, instead of `refs/notes/commits`.
+ This overrides the `core.notesRef` setting.
+
+'GIT_NOTES_DISPLAY_REF'::
+ Colon-delimited list of refs or globs indicating which refs,
+ in addition to the default from `core.notesRef` or
+ 'GIT_NOTES_REF', to read notes from when showing commit
+ messages.
+ This overrides the `notes.displayRef` setting.
++
+A warning will be issued for refs that do not exist, but a glob that
+does not match any refs is silently ignored.
+
+'GIT_NOTES_REWRITE_MODE'::
+ When copying notes during a rewrite, what to do if the target
+ commit already has a note.
+ Must be one of `overwrite`, `concatenate`, and `ignore`.
+ This overrides the `core.rewriteMode` setting.
+
+'GIT_NOTES_REWRITE_REF'::
+ When rewriting commits, which notes to copy from the original
+ to the rewritten commit. Must be a colon-delimited list of
+ refs or globs.
++
+If not set in the environment, the list of notes to copy depends
+on the `notes.rewrite.<command>` and `notes.rewriteRef` settings.

-----------
-Runs 'git-fetch' with the given parameters, and calls 'git-merge'
-to merge the retrieved head(s) into the current branch.
-With `--rebase`, calls 'git-rebase' instead of 'git-merge'.
-Note that you can use `.` (current directory) as the
-<repository> to pull from the local repository -- this is useful
-when merging local branches into the current branch.
+Incorporates changes from a remote repository into the current
+branch. In its default mode, `git pull` is shorthand for
+`git fetch` followed by `git merge FETCH_HEAD`.
-Also note that options meant for 'git-pull' itself and underlying
-'git-merge' must be given before the options meant for 'git-fetch'.
+More precisely, 'git pull' runs 'git fetch' with the given
+parameters and calls 'git merge' to merge the retrieved branch
+heads into the current branch.
+With `--rebase`, it runs 'git rebase' instead of 'git merge'.
+
+<repository> should be the name of a remote repository as
+passed to linkgit:git-fetch[1]. <refspec> can name an
+arbitrary remote ref (for example, the name of a tag) or even
+a collection of refs with corresponding remote-tracking branches
+(e.g., refs/heads/{asterisk}:refs/remotes/origin/{asterisk}),
+but usually it is the name of a branch in the remote repository.
+
+Default values for <repository> and <branch> are read from the
+"remote" and "merge" configuration for the current branch
+as set by linkgit:git-branch[1] `--track`.
+
+Assume the following history exists and the current branch is
+"`master`":
+
+------------
+ A---B---C master on origin
+ /
+ D---E---F---G master
+------------
+
+Then "`git pull`" will fetch and replay the changes from the remote
+`master` branch since it diverged from the local `master` (i.e., `E`)
+until its current commit (`C`) on top of `master` and record the
+result in a new commit along with the names of the two parent commits
+and a log message from the user describing the changes.
+
+------------
+ A---B---C remotes/origin/master
+ / \
+ D---E---F---G---H master
+------------
+
+See linkgit:git-merge[1] for details, including how conflicts
+are presented and handled.
+
+In git 1.7.0 or later, to cancel a conflicting merge, use
+`git reset --merge`. *Warning*: In older versions of git, running 'git pull'
+with uncommitted changes is discouraged: while possible, it leaves you
+in a state that may be hard to back out of in the case of a conflict.
+
+If any of the remote changes overlap with local uncommitted changes,
+the merge will be automatically cancelled and the work tree untouched.
+It is generally best to get any local changes in working order before
+pulling or stash them away with linkgit:git-stash[1].

+Using --recurse-submodules can only fetch new commits in already checked
+out submodules right now. When e.g. upstream added a new submodule in the
+just fetched commits of the superproject the submodule itself can not be
+fetched, making it impossible to check out that submodule later without

+git-remote-ext - Bridge smart transport to external command.
+
+SYNOPSIS
+--------
+[verse]
+git remote add <nick> "ext::<command>[ <arguments>...]"
+
+DESCRIPTION
+-----------
+This remote helper uses the specified '<command>' to connect
+to a remote git server.
+
+Data written to stdin of the specified '<command>' is assumed
+to be sent to a git:// server, git-upload-pack, git-receive-pack
+or git-upload-archive (depending on situation), and data read
+from stdout of <command> is assumed to be received from
+the same service.
+
+Command and arguments are separated by an unescaped space.
+
+The following sequences have a special meaning:
+
+'% '::
+ Literal space in command or argument.
+
+'%%'::
+ Literal percent sign.
+
+'%s'::
+ Replaced with name (receive-pack, upload-pack, or
+ upload-archive) of the service git wants to invoke.
+
+'%S'::
+ Replaced with long name (git-receive-pack,
+ git-upload-pack, or git-upload-archive) of the service
+ git wants to invoke.
+
+'%G' (must be the first characters in an argument)::
+ This argument will not be passed to '<command>'. Instead, it
+ will cause the helper to start by sending git:// service requests to
+ the remote side with the service field set to an appropriate value and
+ the repository field set to rest of the argument. Default is not to send
+ such a request.
++
+This is useful if remote side is git:// server accessed over
+some tunnel.
+
+'%V' (must be first characters in argument)::
+ This argument will not be passed to '<command>'. Instead it sets
+ the vhost field in the git:// service request (to rest of the argument).
+ Default is not to send vhost in such request (if sent).
+
+ENVIRONMENT VARIABLES:
+----------------------
+
+GIT_TRANSLOOP_DEBUG::
+ If set, prints debugging information about various reads/writes.
+
+ENVIRONMENT VARIABLES PASSED TO COMMAND:
+----------------------------------------
+
+GIT_EXT_SERVICE::
+ Set to long name (git-upload-pack, etc...) of service helper needs
+ to invoke.
+
+GIT_EXT_SERVICE_NOPREFIX::
+ Set to long name (upload-pack, etc...) of service helper needs
+ to invoke.
+
+
+EXAMPLES:
+---------
+This remote helper is transparently used by git when
+you use commands such as "git fetch <URL>", "git clone <URL>",
+, "git push <URL>" or "git remote add <nick> <URL>", where <URL>
+begins with `ext::`. Examples:
+
+"ext::ssh -i /home/foo/.ssh/somekey user@host.example %S 'foo/repo'"::
+ Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
+ keypair and user as user on remote side. This avoids needing to
+ edit .ssh/config.
+
+"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"::
+ Represents repository with path /somerepo accessable over
+ git protocol at abstract namespace address /git-server.
+
+"ext::git-server-alias foo %G/repo"::
+ Represents a repository with path /repo accessed using the
+ helper program "git-server-alias foo". The path to the
+ repository and type of request are not passed on the command
+ line but as part of the protocol stream, as usual with git://
+ protocol.
+
+"ext::git-server-alias foo %G/repo %Vfoo"::
+ Represents a repository with path /repo accessed using the
+ helper program "git-server-alias foo". The hostname for the
+ remote server passed in the protocol stream will be "foo"
+ (this allows multiple virtual git servers to share a
+ link-level address).
+
+"ext::git-server-alias foo %G/repo% with% spaces %Vfoo"::
+ Represents a repository with path '/repo with spaces' accessed
+ using the helper program "git-server-alias foo". The hostname for
+ the remote server passed in the protocol stream will be "foo"
+ (this allows multiple virtual git servers to share a
+ link-level address).
+
+"ext::git-ssl foo.example /bar"::
+ Represents a repository accessed using the helper program
+ "git-ssl foo.example /bar". The type of request can be
+ determined by the helper using environment variables (see
+ above).

+SYNOPSIS

+
+DESCRIPTION
+-----------
+This helper uses specified file descriptors to connect to a remote git server.
+This is not meant for end users but for programs and scripts calling git
+fetch, push or archive.
+
+If only <infd> is given, it is assumed to be a bidirectional socket connected
+to remote git server (git-upload-pack, git-receive-pack or
+git-upload-achive). If both <infd> and <outfd> are given, they are assumed
+to be pipes connected to a remote git server (<infd> being the inbound pipe
+and <outfd> being the outbound pipe.
+
+It is assumed that any handshaking procedures have already been completed
+(such as sending service request for git://) before this helper is started.
+
+<anything> can be any string. It is ignored. It is meant for providing

-git-remote-helpers - Helper programs for interoperation with remote git
+git-remote-helpers - Helper programs to interact with remote repositories
SYNOPSIS
--------
-'git remote-<transport>' <remote>
+[verse]
+'git remote-<transport>' <repository> [<URL>]
DESCRIPTION
-----------
-These programs are normally not used directly by end users, but are
-invoked by various git programs that interact with remote repositories
-when the repository they would operate on will be accessed using
-transport code not linked into the main git binary. Various particular
-helper programs will behave as documented here.
+Remote helper programs are normally not used directly by end users,
+but they are invoked by git when it needs to interact with remote
+repositories git does not support natively. A given helper will
+implement a subset of the capabilities documented here. When git
+needs to interact with a repository using a remote helper, it spawns
+the helper as an independent process, sends commands to the helper's
+standard input, and expects results from the helper's standard
+output. Because a remote helper runs as an independent process from
+git, there is no need to re-link git to add a new helper, nor any
+need to link the helper with the implementation of git.
+
+Every helper must support the "capabilities" command, which git
+uses to determine what other commands the helper will accept. Those
+other commands can be used to discover and update remote refs,
+transport objects between the object database and the remote repository,
+and update the local object store.
+
+Git comes with a "curl" family of remote helpers, that handle various
+transport protocols, such as 'git-remote-http', 'git-remote-https',
+'git-remote-ftp' and 'git-remote-ftps'. They implement the capabilities
+'fetch', 'option', and 'push'.
+
+INPUT FORMAT
+------------
+
+Git sends the remote helper a list of commands on standard input, one
+per line. The first command is always the 'capabilities' command, in
+response to which the remote helper must print a list of the
+capabilities it supports (see below) followed by a blank line. The
+response to the capabilities command determines what commands Git uses
+in the remainder of the command stream.
+
+The command stream is terminated by a blank line. In some cases
+(indicated in the documentation of the relevant commands), this blank
+line is followed by a payload in some other protocol (e.g., the pack
+protocol), while in others it indicates the end of input.
+
+Capabilities
+~~~~~~~~~~~~
+
+Each remote helper is expected to support only a subset of commands.
+The operations a helper supports are declared to git in the response
+to the `capabilities` command (see COMMANDS, below).
+
+'option'::
+ For specifying settings like `verbosity` (how much output to
+ write to stderr) and `depth` (how much history is wanted in the
+ case of a shallow clone) that affect how other commands are
+ carried out.
+
+'connect'::
+ For fetching and pushing using git's native packfile protocol
+ that requires a bidirectional, full-duplex connection.
+
+'push'::
+ For listing remote refs and pushing specified objects from the
+ local object store to remote refs.
+
+'fetch'::
+ For listing remote refs and fetching the associated history to
+ the local object store.
+
+'import'::
+ For listing remote refs and fetching the associated history as
+ a fast-import stream.
+
+'refspec' <refspec>::
+ This modifies the 'import' capability, allowing the produced
+ fast-import stream to modify refs in a private namespace
+ instead of writing to refs/heads or refs/remotes directly.
+ It is recommended that all importers providing the 'import'
+ capability use this.
++
+A helper advertising the capability
+`refspec refs/heads/{asterisk}:refs/svn/origin/branches/{asterisk}`
+is saying that, when it is asked to `import refs/heads/topic`, the
+stream it outputs will update the `refs/svn/origin/branches/topic`
+ref.
++
+This capability can be advertised multiple times. The first
+applicable refspec takes precedence. The left-hand of refspecs
+advertised with this capability must cover all refs reported by
+the list command. If no 'refspec' capability is advertised,
+there is an implied `refspec {asterisk}:{asterisk}`.
+
+Capabilities for Pushing
+~~~~~~~~~~~~~~~~~~~~~~~~
+'connect'::
+ Can attempt to connect to 'git receive-pack' (for pushing),
+ 'git upload-pack', etc for communication using the
+ packfile protocol.
++
+Supported commands: 'connect'.
+
+'push'::
+ Can discover remote refs and push local commits and the
+ history leading up to them to new or existing remote refs.
++
+Supported commands: 'list for-push', 'push'.
+
+If a helper advertises both 'connect' and 'push', git will use
+'connect' if possible and fall back to 'push' if the helper requests
+so when connecting (see the 'connect' command under COMMANDS).
+
+Capabilities for Fetching
+~~~~~~~~~~~~~~~~~~~~~~~~~
+'connect'::
+ Can try to connect to 'git upload-pack' (for fetching),
+ 'git receive-pack', etc for communication using the
+ packfile protocol.
++
+Supported commands: 'connect'.
+
+'fetch'::
+ Can discover remote refs and transfer objects reachable from
+ them to the local object store.
++
+Supported commands: 'list', 'fetch'.
+
+'import'::
+ Can discover remote refs and output objects reachable from
+ them as a stream in fast-import format.
++
+Supported commands: 'list', 'import'.
+
+If a helper advertises 'connect', git will use it if possible and
+fall back to another capability if the helper requests so when
+connecting (see the 'connect' command under COMMANDS).
+When choosing between 'fetch' and 'import', git prefers 'fetch'.
+Other frontends may have some other order of preference.
+
+'refspec' <refspec>::
+ This modifies the 'import' capability.
++
+A helper advertising
+`refspec refs/heads/{asterisk}:refs/svn/origin/branches/{asterisk}`
+in its capabilities is saying that, when it handles
+`import refs/heads/topic`, the stream it outputs will update the
+`refs/svn/origin/branches/topic` ref.
++
+This capability can be advertised multiple times. The first
+applicable refspec takes precedence. The left-hand of refspecs
+advertised with this capability must cover all refs reported by
+the list command. If no 'refspec' capability is advertised,
+there is an implied `refspec {asterisk}:{asterisk}`.
+
+INVOCATION
+----------
+
+Remote helper programs are invoked with one or (optionally) two
+arguments. The first argument specifies a remote repository as in git;
+it is either the name of a configured remote or a URL. The second
+argument specifies a URL; it is usually of the form
+'<transport>://<address>', but any arbitrary string is possible.
+The 'GIT_DIR' environment variable is set up for the remote helper
+and can be used to determine where to store additional data or from
+which directory to invoke auxiliary git commands.
+
+When git encounters a URL of the form '<transport>://<address>', where
+'<transport>' is a protocol that it cannot handle natively, it
+automatically invokes 'git remote-<transport>' with the full URL as
+the second argument. If such a URL is encountered directly on the
+command line, the first argument is the same as the second, and if it
+is encountered in a configured remote, the first argument is the name
+of that remote.
+
+A URL of the form '<transport>::<address>' explicitly instructs git to
+invoke 'git remote-<transport>' with '<address>' as the second
+argument. If such a URL is encountered directly on the command line,
+the first argument is '<address>', and if it is encountered in a
+configured remote, the first argument is the name of that remote.
+
+Additionally, when a configured remote has 'remote.<name>.vcs' set to
+'<transport>', git explicitly invokes 'git remote-<transport>' with
+'<name>' as the first argument. If set, the second argument is
+'remote.<name>.url'; otherwise, the second argument is omitted.

DESCRIPTION
-----------
-Sets the current head to the specified commit and optionally resets the
-index and working tree to match.
+In the first and second form, copy entries from <commit> to the index.
+In the third form, set the current branch head (HEAD) to <commit>, optionally
+modifying index and working tree to match. The <commit> defaults to HEAD
+in all forms.

-commit (or set of commits) and want to redo that part without showing
-the undo in the history.
+'git reset' [-q] [<commit>] [--] <paths>...::
+ This form resets the index entries for all <paths> to their
+ state at <commit>. (It does not affect the working tree, nor

++
+This means that `git reset <paths>` is the opposite of `git add
+<paths>`.
++
+After running `git reset <paths>` to update the index entry, you can
+use linkgit:git-checkout[1] to check the contents out of the index to
+the working tree.
+Alternatively, using linkgit:git-checkout[1] and specifying a commit, you
+can copy the contents of a path out of a commit to the index and to the
+working tree in one go.

+you can use it to selectively reset hunks. See the ``Interactive Mode''
+section of linkgit:git-add[1] to learn how to operate the `\--patch` mode.
-The second and third forms with 'paths' and/or --patch are used to
-revert selected paths in the index from a given commit, without moving

+'git reset' --<mode> [<commit>]::

-SPECIFYING REVISIONS
---------------------
-
-A revision parameter typically, but not necessarily, names a
-commit object. They use what is called an 'extended SHA1'
-syntax. Here are various ways to spell object names. The
-ones listed near the end of this list are to name trees and
-blobs contained in a commit.
-
-* The full SHA1 object name (40-byte hexadecimal string), or
- a substring of such that is unique within the repository.
- E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
- name the same commit object if there are no other object in
- your repository whose object name starts with dae86e.
-
-* An output from 'git-describe'; i.e. a closest tag, optionally
- followed by a dash and a number of commits, followed by a dash, a
- `g`, and an abbreviated object name.
-
-* A symbolic ref name. E.g. 'master' typically means the commit
- object referenced by $GIT_DIR/refs/heads/master. If you
- happen to have both heads/master and tags/master, you can
- explicitly say 'heads/master' to tell git which one you mean.
- When ambiguous, a `<name>` is disambiguated by taking the
- first match in the following rules:
-
- . if `$GIT_DIR/<name>` exists, that is what you mean (this is usually
- useful only for `HEAD`, `FETCH_HEAD`, `ORIG_HEAD` and `MERGE_HEAD`);
-
- . otherwise, `$GIT_DIR/refs/<name>` if exists;
-
- . otherwise, `$GIT_DIR/refs/tags/<name>` if exists;
-
- . otherwise, `$GIT_DIR/refs/heads/<name>` if exists;
-
- . otherwise, `$GIT_DIR/refs/remotes/<name>` if exists;
-
- . otherwise, `$GIT_DIR/refs/remotes/<name>/HEAD` if exists.
-+
-HEAD names the commit your changes in the working tree is based on.
-FETCH_HEAD records the branch you fetched from a remote repository
-with your last 'git-fetch' invocation.
-ORIG_HEAD is created by commands that moves your HEAD in a drastic
-way, to record the position of the HEAD before their operation, so that
-you can change the tip of the branch back to the state before you ran
-them easily.
-MERGE_HEAD records the commit(s) you are merging into your branch
-when you run 'git-merge'.
-
-* A ref followed by the suffix '@' with a date specification
- enclosed in a brace
- pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
- second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
- of the ref at a prior point in time. This suffix may only be
- used immediately following a ref name and the ref must have an
- existing log ($GIT_DIR/logs/<ref>). Note that this looks up the state
- of your *local* ref at a given time; e.g., what was in your local
- `master` branch last week. If you want to look at commits made during
- certain times, see `--since` and `--until`.
-
-* A ref followed by the suffix '@' with an ordinal specification
- enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
- the n-th prior value of that ref. For example 'master@\{1\}'
- is the immediate prior value of 'master' while 'master@\{5\}'
- is the 5th prior value of 'master'. This suffix may only be used
- immediately following a ref name and the ref must have an existing
- log ($GIT_DIR/logs/<ref>).
-
-* You can use the '@' construct with an empty ref part to get at a
- reflog of the current branch. For example, if you are on the
- branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.
-
-* The special construct '@\{-<n>\}' means the <n>th branch checked out
- before the current one.
-
-* A suffix '{caret}' to a revision parameter means the first parent of
- that commit object. '{caret}<n>' means the <n>th parent (i.e.
- 'rev{caret}'
- is equivalent to 'rev{caret}1'). As a special rule,
- 'rev{caret}0' means the commit itself and is used when 'rev' is the
- object name of a tag object that refers to a commit object.
-
-* A suffix '{tilde}<n>' to a revision parameter means the commit
- object that is the <n>th generation grand-parent of the named
- commit object, following only the first parent. I.e. rev~3 is
- equivalent to rev{caret}{caret}{caret} which is equivalent to
- rev{caret}1{caret}1{caret}1. See below for a illustration of
- the usage of this form.
-
-* A suffix '{caret}' followed by an object type name enclosed in
- brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object
- could be a tag, and dereference the tag recursively until an
- object of that type is found or the object cannot be
- dereferenced anymore (in which case, barf). `rev{caret}0`
- introduced earlier is a short-hand for `rev{caret}\{commit\}`.
-
-* A suffix '{caret}' followed by an empty brace pair
- (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag,
- and dereference the tag recursively until a non-tag object is
- found.
-
-* A colon, followed by a slash, followed by a text: this names
- a commit whose commit message starts with the specified text.
- This name returns the youngest matching commit which is
- reachable from any ref. If the commit message starts with a
- '!', you have to repeat that; the special sequence ':/!',
- followed by something else than '!' is reserved for now.
-
-* A suffix ':' followed by a path; this names the blob or tree
- at the given path in the tree-ish object named by the part
- before the colon.
-
-* A colon, optionally followed by a stage number (0 to 3) and a
- colon, followed by a path; this names a blob object in the
- index at the given path. Missing stage number (and the colon
- that follows it) names a stage 0 entry. During a merge, stage
- 1 is the common ancestor, stage 2 is the target branch's version
- (typically the current branch), and stage 3 is the version from
- the branch being merged.
-
-Here is an illustration, by Jon Loeliger. Both commit nodes B
-and C are parents of commit node A. Parent commits are ordered
-left-to-right.

-
-SPECIFYING RANGES
------------------
-
-History traversing commands such as 'git-log' operate on a set
-of commits, not just a single commit. To these commands,
-specifying a single revision with the notation described in the
-previous section means the set of commits reachable from that
-commit, following the commit ancestry chain.
-
-To exclude commits reachable from a commit, a prefix `{caret}`
-notation is used. E.g. `{caret}r1 r2` means commits reachable
-from `r2` but exclude the ones reachable from `r1`.
-
-This set operation appears so often that there is a shorthand
-for it. When you have two commits `r1` and `r2` (named according
-to the syntax explained in SPECIFYING REVISIONS above), you can ask
-for commits that are reachable from r2 excluding those that are reachable
-from r1 by `{caret}r1 r2` and it can be written as `r1..r2`.
-
-A similar notation `r1\...r2` is called symmetric difference
-of `r1` and `r2` and is defined as
-`r1 r2 --not $(git merge-base --all r1 r2)`.
-It is the set of commits that are reachable from either one of
-`r1` or `r2` but not from both.
-
-Two other shorthands for naming a set that is formed by a commit
-and its parent commits exist. The `r1{caret}@` notation means all
-parents of `r1`. `r1{caret}!` includes commit `r1` but excludes
-all of its parents.
-
-Here are a handful of examples:
-
- D G H D
- D F G H I J D F
- ^G D H D
- ^D B E I J F B
- B...C G H D E B C
- ^D B C E I J F B C

+~~~~~~~~~~~~~~~~
+
+The porcelain format is similar to the short format, but is guaranteed
+not to change in a backwards-incompatible way between git versions or
+based on user configuration. This makes it ideal for parsing by scripts.
+The description of the short format above also describes the porcelain
+format, with a few exceptions:
+
+1. The user's color.status configuration is not respected; color will
+ always be off.
+
+2. The user's status.relativePaths configuration is not respected; paths
+ shown will always be relative to the repository root.
+
+There is also an alternate -z format recommended for machine parsing. In
+that format, the status field is the same, but some other things
+change. First, the '\->' is omitted from rename entries and the field
+order is reversed (e.g 'from \-> to' becomes 'to from'). Second, a NUL
+(ASCII 0) follows each filename, replacing space as a field separator
+and the terminating newline (but a space still separates the status
+field from the first filename). Third, filenames containing special
+characters are not specially formatted; no quoting or
+backslash-escaping is performed. Fourth, there is no branch line.

-When `core.autocrlf` is true, it means that the platform wants
-CRLF line endings for files in the working tree, and you want to
-convert them back to the normal LF line endings when checking

+ This setting forces git to normalize line endings to LF on
+ checkin and prevents conversion to CRLF when the file is
+ checked out.
-When `core.autocrlf` is set to "input", line endings are
-converted to LF upon checkin, but there is no conversion done
-upon checkout.
+Backwards compatibility with `crlf` attribute
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For backwards compatibility, the `crlf` attribute is interpreted as
+follows:
+
+------------------------
+crlf text
+-crlf -text
+crlf=input eol=lf
+------------------------
+
+End-of-line conversion
+^^^^^^^^^^^^^^^^^^^^^^
+
+While git normally leaves file contents alone, it can be configured to
+normalize line endings to LF in the repository and, optionally, to
+convert them to CRLF when files are checked out.
+
+Here is an example that will make git normalize .txt, .vcproj and .sh
+files, ensure that .vcproj files have CRLF and .sh files have LF in
+the working directory, and prevent .jpg files from being normalized
+regardless of their content.
+
+------------------------
+*.txt text
+*.vcproj eol=crlf
+*.sh eol=lf
+*.jpg -text
+------------------------
+
+Other source code management systems normalize all text files in their
+repositories, and there are two ways to enable similar automatic
+normalization in git.
+
+If you simply want to have CRLF line endings in your working directory
+regardless of the repository you are working with, you can set the
+config variable "core.autocrlf" without changing any attributes.
+
+------------------------
+[core]
+ autocrlf = true
+------------------------
+
+This does not force normalization of all text files, but does ensure
+that text files that you introduce to the repository have their line
+endings normalized to LF when they are added, and that files that are
+already normalized in the repository stay normalized.
+
+If you want to interoperate with a source code management system that
+enforces end-of-line normalization, or you simply want all text files
+in your repository to be normalized, you should instead set the `text`
+attribute to "auto" for _all_ files.
+
+------------------------
+* text=auto
+------------------------
+
+This ensures that all files that git considers to be text will have
+normalized (LF) line endings in the repository. The `core.eol`
+configuration variable controls which line endings git will use for
+normalized files in your working directory; the default is to use the
+native line ending for your platform, or CRLF if `core.autocrlf` is
+set.
+
+NOTE: When `text=auto` normalization is enabled in an existing
+repository, any text files containing CRLFs should be normalized. If
+they are not they will be normalized the next time someone tries to
+change them, causing unfortunate misattribution. From a clean working
+directory:
+
+-------------------------------------------------
+$ echo "* text=auto" >>.gitattributes
+$ rm .git/index # Remove the index to force git to
+$ git reset # re-scan the working directory
+$ git status # Show files that will be normalized
+$ git add -u
+$ git add .gitattributes
+$ git commit -m "Introduce end-of-line normalization"
+-------------------------------------------------
+
+If any files that should not be normalized show up in 'git status',
+unset their `text` attribute before running 'git add -u'.
+
+------------------------
+manual.pdf -text
+------------------------
+
+Conversely, text files that git does not detect can have normalization
+enabled manually.

+Merging branches with differing checkin/checkout attributes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you have added attributes to a file that cause the canonical
+repository format for that file to change, such as adding a
+clean/smudge filter or text/eol/ident attributes, merging anything
+where the attribute is not in place would normally cause merge
+conflicts.
+
+To prevent these unnecessary merge conflicts, git can be told to run a
+virtual check-out and check-in of all three stages of a file when
+resolving a three-way merge by setting the `merge.renormalize`
+configuration variable. This prevents changes caused by check-in
+conversion from causing spurious merge conflicts when a converted file
+is merged with an unconverted file.
+

should generate it separately and send it as a comment _in
addition to_ the usual binary diff that you might send.
+Because text conversion can be slow, especially when doing a
+large number of them with `git log -p`, git provides a mechanism
+to cache the output and use it in future diffs. To enable
+caching, set the "cachetextconv" variable in your diff driver's
+config. For example:
+
+------------------------
+[diff "jpg"]
+ textconv = exif
+ cachetextconv = true
+------------------------
+
+This will cache the result of running "exif" on each blob
+indefinitely. If you change the textconv config variable for a
+diff driver, git will automatically invalidate the cache entries
+and re-run the textconv filter. If you want to invalidate the
+cache manually (e.g., because your version of "exif" was updated
+and now produces better output), you can remove the cache
+manually with `git update-ref -d refs/notes/textconv/jpg` (where
+"jpg" is the name of the diff driver, as in the example above).
+
+Choosing textconv versus external diff
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you want to show differences between binary or specially-formatted
+blobs in your repository, you can choose to use either an external diff
+command, or to use textconv to convert them to a diff-able text format.
+Which method you choose depends on your exact situation.
+
+The advantage of using an external diff command is flexibility. You are
+not bound to find line-oriented changes, nor is it necessary for the
+output to resemble unified diff. You are free to locate and report
+changes in the most appropriate way for your data format.
+
+A textconv, by comparison, is much more limiting. You provide a
+transformation of the data into a line-oriented text format, and git
+uses its regular diff tools to generate the output. There are several
+advantages to choosing this method:
+
+1. Ease of use. It is often much simpler to write a binary to text
+ transformation than it is to perform your own diff. In many cases,
+ existing programs can be used as textconv filters (e.g., exif,
+ odt2txt).
+
+2. Git diff features. By performing only the transformation step
+ yourself, you can still utilize many of git's diff features,
+ including colorization, word-diff, and combined diffs for merges.
+
+3. Caching. Textconv caching can speed up repeated diffs, such as those
+ you might trigger by running `git log -p`.
+
+
+Marking files as binary
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Git usually guesses correctly whether a blob contains text or binary
+data by examining the beginning of the contents. However, sometimes you
+may want to override its decision, either because a blob contains binary
+data later in the file, or because the content, while technically
+composed of text characters, is opaque to a human reader. For example,
+many postscript files contain only ascii characters, but produce noisy
+and meaningless diffs.
+
+The simplest way to mark a file as binary is to unset the diff
+attribute in the `.gitattributes` file:
+
+------------------------
+*.ps -diff
+------------------------
+
+This will cause git to generate `Binary files differ` (or a binary
+patch, if binary patches are enabled) instead of a regular diff.
+
+However, one may also want to specify other diff driver attributes. For
+example, you might want to use `textconv` to convert postscript files to
+an ascii representation for human viewing, but otherwise treat them as
+binary files. You cannot specify both `-diff` and `diff=ps` attributes.
+The solution is to use the `diff.*.binary` config option:
+
+------------------------
+[diff "ps"]
+ textconv = ps2ascii
+ binary = true

+gitnamespaces(7)
+================
+
+NAME
+----
+gitnamespaces - Git namespaces
+
+SYNOPSIS
+--------
+[verse]
+GIT_NAMESPACE=<namespace> 'git upload-pack'
+GIT_NAMESPACE=<namespace> 'git receive-pack'
+
+
+DESCRIPTION
+-----------
+
+Git supports dividing the refs of a single repository into multiple
+namespaces, each of which has its own branches, tags, and HEAD. Git can
+expose each namespace as an independent repository to pull from and push
+to, while sharing the object store, and exposing all the refs to
+operations such as linkgit:git-gc[1].
+
+Storing multiple repositories as namespaces of a single repository
+avoids storing duplicate copies of the same objects, such as when
+storing multiple branches of the same source. The alternates mechanism
+provides similar support for avoiding duplicates, but alternates do not
+prevent duplication between new objects added to the repositories
+without ongoing maintenance, while namespaces do.
+
+To specify a namespace, set the `GIT_NAMESPACE` environment variable to
+the namespace. For each ref namespace, git stores the corresponding
+refs in a directory under `refs/namespaces/`. For example,
+`GIT_NAMESPACE=foo` will store refs under `refs/namespaces/foo/`. You
+can also specify namespaces via the `--namespace` option to
+linkgit:git[1].
+
+Note that namespaces which include a `/` will expand to a hierarchy of
+namespaces; for example, `GIT_NAMESPACE=foo/bar` will store refs under
+`refs/namespaces/foo/refs/namespaces/bar/`. This makes paths in
+`GIT_NAMESPACE` behave hierarchically, so that cloning with
+`GIT_NAMESPACE=foo/bar` produces the same result as cloning with
+`GIT_NAMESPACE=foo` and cloning from that repo with `GIT_NAMESPACE=bar`. It
+also avoids ambiguity with strange namespace paths such as `foo/refs/heads/`,
+which could otherwise generate directory/file conflicts within the `refs`
+directory.
+
+linkgit:git-upload-pack[1] and linkgit:git-receive-pack[1] rewrite the
+names of refs as specified by `GIT_NAMESPACE`. git-upload-pack and
+git-receive-pack will ignore all references outside the specified
+namespace.
+
+The smart HTTP server, linkgit:git-http-backend[1], will pass
+GIT_NAMESPACE through to the backend programs; see
+linkgit:git-http-backend[1] for sample configuration to expose
+repository namespaces as repositories.
+
+For a simple local test, you can use linkgit:git-remote-ext[1]:
+
+----------
+git clone ext::'git --namespace=foo %s /tmp/prefixed.git'
+----------
+
+SECURITY
+--------
+
+Anyone with access to any namespace within a repository can potentially
+access objects from any other namespace stored in the same repository.
+You can't directly say "give me object ABCD" if you don't have a ref to
+it, but you can do some other sneaky things like:
+
+. Claiming to push ABCD, at which point the server will optimize out the
+ need for you to actually send it. Now you have a ref to ABCD and can
+ fetch it (claiming not to have it, of course).
+
+. Requesting other refs, claiming that you have ABCD, at which point the
+ server may generate deltas against ABCD.
+
+None of this causes a problem if you only host public repositories, or
+if everyone who may read one namespace may also read everything in every
+other namespace (for instance, if everyone in an organization has read
+permission to every repository).

+NAME
+----
+gitweb.conf - Gitweb (git web interface) configuration file
+
+SYNOPSIS
+--------
+/etc/gitweb.conf, /etc/gitweb-common.conf, $GITWEBDIR/gitweb_config.perl
+
+DESCRIPTION
+-----------
+
+The gitweb CGI script for viewing Git repositories over the web uses a
+perl script fragment as its configuration file. You can set variables
+using "`our $variable = value`"; text from a "#" character until the
+end of a line is ignored. See *perlsyn*(1) for details.
+
+An example:
+
+ # gitweb configuration file for http://git.example.org
+ #
+ our $projectroot = "/srv/git"; # FHS recommendation
+ our $site_name = 'Example.org >> Repos';
+
+
+The configuration file is used to override the default settings that
+were built into gitweb at the time the 'gitweb.cgi' script was generated.
+
+While one could just alter the configuration settings in the gitweb
+CGI itself, those changes would be lost upon upgrade. Configuration
+settings might also be placed into a file in the same directory as the
+CGI script with the default name 'gitweb_config.perl' -- allowing
+one to have multiple gitweb instances with different configurations by
+the use of symlinks.
+
+Note that some configuration can be controlled on per-repository rather than
+gitweb-wide basis: see "Per-repository gitweb configuration" subsection on
+linkgit:gitweb[1] manpage.
+
+
+DISCUSSION
+----------
+Gitweb reads configuration data from the following sources in the
+following order:
+
+ * built-in values (some set during build stage),
+
+ * common system-wide configuration file (defaults to
+ '/etc/gitweb-common.conf'),
+
+ * either per-instance configuration file (defaults to 'gitweb_config.perl'
+ in the same directory as the installed gitweb), or if it does not exists
+ then fallback system-wide configuration file (defaults to '/etc/gitweb.conf').
+
+Values obtained in later configuration files override values obtained earlier
+in the above sequence.
+
+Locations of the common system-wide configuration file, the fallback
+system-wide configuration file and the per-instance configuration file
+are defined at compile time using build-time Makefile configuration
+variables, respectively `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM`
+and `GITWEB_CONFIG`.
+
+You can also override locations of gitweb configuration files during
+runtime by setting the following environment variables:
+`GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` and `GITWEB_CONFIG`
+to a non-empty value.
+
+
+The syntax of the configuration files is that of Perl, since these files are
+handled by sourcing them as fragments of Perl code (the language that
+gitweb itself is written in). Variables are typically set using the
+`our` qualifier (as in "`our $variable = <value>;`") to avoid syntax
+errors if a new version of gitweb no longer uses a variable and therefore
+stops declaring it.
+
+You can include other configuration file using read_config_file()
+subroutine. For example, one might want to put gitweb configuration
+related to access control for viewing repositories via Gitolite (one
+of git repository management tools) in a separate file, e.g. in
+'/etc/gitweb-gitolite.conf'. To include it, put
+
+--------------------------------------------------
+read_config_file("/etc/gitweb-gitolite.conf");
+--------------------------------------------------
+
+somewhere in gitweb configuration file used, e.g. in per-installation
+gitweb configuration file. Note that read_config_file() checks itself
+that the file it reads exists, and does nothing if it is not found.
+It also handles errors in included file.
+
+
+The default configuration with no configuration file at all may work
+perfectly well for some installations. Still, a configuration file is
+useful for customizing or tweaking the behavior of gitweb in many ways, and
+some optional features will not be present unless explicitly enabled using
+the configurable `%features` variable (see also "Configuring gitweb
+features" section below).
+
+
+CONFIGURATION VARIABLES
+-----------------------
+Some configuration variables have their default values (embedded in the CGI
+script) set during building gitweb -- if that is the case, this fact is put
+in their description. See gitweb's 'INSTALL' file for instructions on building
+and installing gitweb.
+
+
+Location of repositories
+~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration variables described below control how gitweb finds
+git repositories, and how repositories are displayed and accessed.
+
+See also "Repositories" and later subsections in linkgit:gitweb[1] manpage.
+
+$projectroot::
+ Absolute filesystem path which will be prepended to project path;
+ the path to repository is `$projectroot/$project`. Set to
+ `$GITWEB_PROJECTROOT` during installation. This variable has to be
+ set correctly for gitweb to find repositories.
++
+For example, if `$projectroot` is set to "/srv/git" by putting the following
+in gitweb config file:
++
+----------------------------------------------------------------------------
+our $projectroot = "/srv/git";
+----------------------------------------------------------------------------
++
+then
++
+------------------------------------------------
+http://git.example.com/gitweb.cgi?p=foo/bar.git
+------------------------------------------------
++
+and its path_info based equivalent
++
+------------------------------------------------
+http://git.example.com/gitweb.cgi/foo/bar.git
+------------------------------------------------
++
+will map to the path '/srv/git/foo/bar.git' on the filesystem.
+
+$projects_list::
+ Name of a plain text file listing projects, or a name of directory
+ to be scanned for projects.
++
+Project list files should list one project per line, with each line
+having the following format
++
+-----------------------------------------------------------------------------
+<URI-encoded filesystem path to repository> SP <URI-encoded repository owner>
+-----------------------------------------------------------------------------
++
+The default value of this variable is determined by the `GITWEB_LIST`
+makefile variable at installation time. If this variable is empty, gitweb
+will fall back to scanning the `$projectroot` directory for repositories.
+
+$project_maxdepth::
+ If `$projects_list` variable is unset, gitweb will recursively
+ scan filesystem for git repositories. The `$project_maxdepth`
+ is used to limit traversing depth, relative to `$projectroot`
+ (starting point); it means that directories which are further
+ from `$projectroot` than `$project_maxdepth` will be skipped.
++
+It is purely performance optimization, originally intended for MacOS X,
+where recursive directory traversal is slow. Gitweb follows symbolic
+links, but it detects cycles, ignoring any duplicate files and directories.
++
+The default value of this variable is determined by the build-time
+configuration variable `GITWEB_PROJECT_MAXDEPTH`, which defaults to
+2007.
+
+$export_ok::
+ Show repository only if this file exists (in repository). Only
+ effective if this variable evaluates to true. Can be set when
+ building gitweb by setting `GITWEB_EXPORT_OK`. This path is
+ relative to `GIT_DIR`. git-daemon[1] uses 'git-daemon-export-ok',
+ unless started with `--export-all`. By default this variable is
+ not set, which means that this feature is turned off.
+
+$export_auth_hook::
+ Function used to determine which repositories should be shown.
+ This subroutine should take one parameter, the full path to
+ a project, and if it returns true, that project will be included
+ in the projects list and can be accessed through gitweb as long
+ as it fulfills the other requirements described by $export_ok,
+ $projects_list, and $projects_maxdepth. Example:
++
+----------------------------------------------------------------------------
+our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; };
+----------------------------------------------------------------------------
++
+though the above might be done by using `$export_ok` instead
++
+----------------------------------------------------------------------------
+our $export_ok = "git-daemon-export-ok";
+----------------------------------------------------------------------------
++
+If not set (default), it means that this feature is disabled.
++
+See also more involved example in "Controlling access to git repositories"
+subsection on linkgit:gitweb[1] manpage.
+
+$strict_export::
+ Only allow viewing of repositories also shown on the overview page.
+ This for example makes `$gitweb_export_ok` file decide if repository is
+ available and not only if it is shown. If `$gitweb_list` points to
+ file with list of project, only those repositories listed would be
+ available for gitweb. Can be set during building gitweb via
+ `GITWEB_STRICT_EXPORT`. By default this variable is not set, which
+ means that you can directly access those repositories that are hidden
+ from projects list page (e.g. the are not listed in the $projects_list
+ file).
+
+
+Finding files
+~~~~~~~~~~~~~
+The following configuration variables tell gitweb where to find files.
+The values of these variables are paths on the filesystem.
+
+$GIT::
+ Core git executable to use. By default set to `$GIT_BINDIR/git`, which
+ in turn is by default set to `$(bindir)/git`. If you use git installed
+ from a binary package, you should usually set this to "/usr/bin/git".
+ This can just be "git" if your web server has a sensible PATH; from
+ security point of view it is better to use absolute path to git binary.
+ If you have multiple git versions installed it can be used to choose
+ which one to use. Must be (correctly) set for gitweb to be able to
+ work.
+
+$mimetypes_file::
+ File to use for (filename extension based) guessing of MIME types before
+ trying '/etc/mime.types'. *NOTE* that this path, if relative, is taken
+ as relative to the current git repository, not to CGI script. If unset,
+ only '/etc/mime.types' is used (if present on filesystem). If no mimetypes
+ file is found, mimetype guessing based on extension of file is disabled.
+ Unset by default.
+
+$highlight_bin::
+ Path to the highlight executable to use (it must be the one from
+ http://www.andre-simon.de[] due to assumptions about parameters and output).
+ By default set to 'highlight'; set it to full path to highlight
+ executable if it is not installed on your web server's PATH.
+ Note that 'highlight' feature must be set for gitweb to actually
+ use syntax hightlighting.
++
+*NOTE*: if you want to add support for new file type (supported by
+"highlight" but not used by gitweb), you need to modify `%highlight_ext`
+or `%highlight_basename`, depending on whether you detect type of file
+based on extension (for example "sh") or on its basename (for example
+"Makefile"). The keys of these hashes are extension and basename,
+respectively, and value for given key is name of syntax to be passed via
+`--syntax <syntax>` to highlighter.
++
+For example if repositories you are hosting use "phtml" extension for
+PHP files, and you want to have correct syntax-highlighting for those
+files, you can add the following to gitweb configuration:
++
+---------------------------------------------------------
+our %highlight_ext;
+$highlight_ext{'phtml'} = 'php';
+---------------------------------------------------------
+
+
+Links and their targets
+~~~~~~~~~~~~~~~~~~~~~~~
+The configuration variables described below configure some of gitweb links:
+their target and their look (text or image), and where to find page
+prerequisites (stylesheet, favicon, images, scripts). Usually they are left
+at their default values, with the possible exception of `@stylesheets`
+variable.
+
+@stylesheets::
+ List of URIs of stylesheets (relative to the base URI of a page). You
+ might specify more than one stylesheet, for example to use "gitweb.css"
+ as base with site specific modifications in a separate stylesheet
+ to make it easier to upgrade gitweb. For example, you can add
+ a `site` stylesheet by putting
++
+----------------------------------------------------------------------------
+push @stylesheets, "gitweb-site.css";
+----------------------------------------------------------------------------
++
+in the gitweb config file. Those values that are relative paths are
+relative to base URI of gitweb.
++
+This list should contain the URI of gitweb's standard stylesheet. The default
+URI of gitweb stylesheet can be set at build time using the `GITWEB_CSS`
+makefile variable. Its default value is 'static/gitweb.css'
+(or 'static/gitweb.min.css' if the `CSSMIN` variable is defined,
+i.e. if CSS minifier is used during build).
++
+*Note*: there is also a legacy `$stylesheet` configuration variable, which was
+used by older gitweb. If `$stylesheet` variable is defined, only CSS stylesheet
+given by this variable is used by gitweb.
+
+$logo::
+ Points to the location where you put 'git-logo.png' on your web
+ server, or to be more the generic URI of logo, 72x27 size). This image
+ is displayed in the top right corner of each gitweb page and used as
+ a logo for the Atom feed. Relative to the base URI of gitweb (as a path).
+ Can be adjusted when building gitweb using `GITWEB_LOGO` variable
+ By default set to 'static/git-logo.png'.
+
+$favicon::
+ Points to the location where you put 'git-favicon.png' on your web
+ server, or to be more the generic URI of favicon, which will be served
+ as "image/png" type. Web browsers that support favicons (website icons)
+ may display them in the browser's URL bar and next to the site name in
+ bookmarks. Relative to the base URI of gitweb. Can be adjusted at
+ build time using `GITWEB_FAVICON` variable.
+ By default set to 'static/git-favicon.png'.
+
+$javascript::
+ Points to the location where you put 'gitweb.js' on your web server,
+ or to be more generic the URI of JavaScript code used by gitweb.
+ Relative to the base URI of gitweb. Can be set at build time using
+ the `GITWEB_JS` build-time configuration variable.
++
+The default value is either 'static/gitweb.js', or 'static/gitweb.min.js' if
+the `JSMIN` build variable was defined, i.e. if JavaScript minifier was used
+at build time. *Note* that this single file is generated from multiple
+individual JavaScript "modules".
+
+$home_link::
+ Target of the home link on the top of all pages (the first part of view
+ "breadcrumbs"). By default it is set to the absolute URI of a current page
+ (to the value of `$my_uri` variable, or to "/" if `$my_uri` is undefined
+ or is an empty string).
+
+$home_link_str::
+ Label for the "home link" at the top of all pages, leading to `$home_link`
+ (usually the main gitweb page, which contains the projects list). It is
+ used as the first component of gitweb's "breadcrumb trail":
+ `<home link> / <project> / <action>`. Can be set at build time using
+ the `GITWEB_HOME_LINK_STR` variable. By default it is set to "projects",
+ as this link leads to the list of projects. Other popular choice it to
+ set it to the name of site.
+
+$logo_url::
+$logo_label::
+ URI and label (title) for the Git logo link (or your site logo,
+ if you chose to use different logo image). By default, these both
+ refer to git homepage, http://git-scm.com[]; in the past, they pointed
+ to git documentation at http://www.kernel.org[].
+
+
+Changing gitweb's look
+~~~~~~~~~~~~~~~~~~~~~~
+You can adjust how pages generated by gitweb look using the variables described
+below. You can change the site name, add common headers and footers for all
+pages, and add a description of this gitweb installation on its main page
+(which is the projects list page), etc.
+
+$site_name::
+ Name of your site or organization, to appear in page titles. Set it
+ to something descriptive for clearer bookmarks etc. If this variable
+ is not set or is, then gitweb uses the value of the `SERVER_NAME`
+ CGI environment variable, setting site name to "$SERVER_NAME Git",
+ or "Untitled Git" if this variable is not set (e.g. if running gitweb
+ as standalone script).
++
+Can be set using the `GITWEB_SITENAME` at build time. Unset by default.
+
+$site_html_head_string::
+ HTML snippet to be included in the <head> section of each page.
+ Can be set using `GITWEB_SITE_HTML_HEAD_STRING` at build time.
+ No default value.
+
+$site_header::
+ Name of a file with HTML to be included at the top of each page.
+ Relative to the directory containing the 'gitweb.cgi' script.
+ Can be set using `GITWEB_SITE_HEADER` at build time. No default
+ value.
+
+$site_footer::
+ Name of a file with HTML to be included at the bottom of each page.
+ Relative to the directory containing the 'gitweb.cgi' script.
+ Can be set using `GITWEB_SITE_FOOTER` at build time. No default
+ value.
+
+$home_text::
+ Name of a HTML file which, if it exists, is included on the
+ gitweb projects overview page ("projects_list" view). Relative to
+ the directory containing the gitweb.cgi script. Default value
+ can be adjusted during build time using `GITWEB_HOMETEXT` variable.
+ By default set to 'indextext.html'.
+
+$projects_list_description_width::
+ The width (in characters) of the "Description" column of the projects list.
+ Longer descriptions will be truncated (trying to cut at word boundary);
+ the full description is available in the 'title' attribute (usually shown on
+ mouseover). The default is 25, which might be too small if you
+ use long project descriptions.
+
+$default_projects_order::
+ Default value of ordering of projects on projects list page, which
+ means the ordering used if you don't explicitly sort projects list
+ (if there is no "o" CGI query parameter in the URL). Valid values
+ are "none" (unsorted), "project" (projects are by project name,
+ i.e. path to repository relative to `$projectroot`), "descr"
+ (project description), "owner", and "age" (by date of most current
+ commit).
++
+Default value is "project". Unknown value means unsorted.
+
+
+Changing gitweb's behavior
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+These configuration variables control _internal_ gitweb behavior.
+
+$default_blob_plain_mimetype::
+ Default mimetype for the blob_plain (raw) view, if mimetype checking
+ doesn't result in some other type; by default "text/plain".
+ Gitweb guesses mimetype of a file to display based on extension
+ of its filename, using `$mimetypes_file` (if set and file exists)
+ and '/etc/mime.types' files (see *mime.types*(5) manpage; only
+ filename extension rules are supported by gitweb).
+
+$default_text_plain_charset::
+ Default charset for text files. If this is not set, the web server
+ configuration will be used. Unset by default.
+
+$fallback_encoding::
+ Gitweb assumes this charset when a line contains non-UTF-8 characters.
+ The fallback decoding is used without error checking, so it can be even
+ "utf-8". The value must be a valid encoding; see the *Encoding::Supported*(3pm)
+ man page for a list. The default is "latin1", aka. "iso-8859-1".
+
+@diff_opts::
+ Rename detection options for git-diff and git-diff-tree. The default is
+ (\'-M'); set it to (\'-C') or (\'-C', \'-C') to also detect copies,
+ or set it to () i.e. empty list if you don't want to have renames
+ detection.
++
+*Note* that rename and especially copy detection can be quite
+CPU-intensive. Note also that non git tools can have problems with
+patches generated with options mentioned above, especially when they
+involve file copies (\'-C') or criss-cross renames (\'-B').
+
+
+Some optional features and policies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Most of features are configured via `%feature` hash; however some of extra
+gitweb features can be turned on and configured using variables described
+below. This list beside configuration variables that control how gitweb
+looks does contain variables configuring administrative side of gitweb
+(e.g. cross-site scripting prevention; admittedly this as side effect
+affects how "summary" pages look like, or load limiting).
+
+@git_base_url_list::
+ List of git base URLs. These URLs are used to generate URLs
+ describing from where to fetch a project, which are shown on
+ project summary page. The full fetch URL is "`$git_base_url/$project`",
+ for each element of this list. You can set up multiple base URLs
+ (for example one for `git://` protocol, and one for `http://`
+ protocol).
++
+Note that per repository configuration can be set in '$GIT_DIR/cloneurl'
+file, or as values of multi-value `gitweb.url` configuration variable in
+project config. Per-repository configuration takes precedence over value
+composed from `@git_base_url_list` elements and project name.
++
+You can setup one single value (single entry/item in this list) at build
+time by setting the `GITWEB_BASE_URL` built-time configuration variable.
+By default it is set to (), i.e. an empty list. This means that gitweb
+would not try to create project URL (to fetch) from project name.
+
+$projects_list_group_categories::
+ Whether to enables the grouping of projects by category on the project
+ list page. The category of a project is determined by the
+ `$GIT_DIR/category` file or the `gitweb.category` variable in each
+ repository's configuration. Disabled by default (set to 0).
+
+$project_list_default_category::
+ Default category for projects for which none is specified. If this is
+ set to the empty string, such projects will remain uncategorized and
+ listed at the top, above categorized projects. Used only if project
+ categories are enabled, which means if `$projects_list_group_categories`
+ is true. By default set to "" (empty string).
+
+$prevent_xss::
+ If true, some gitweb features are disabled to prevent content in
+ repositories from launching cross-site scripting (XSS) attacks. Set this
+ to true if you don't trust the content of your repositories.
+ False by default (set to 0).
+
+$maxload::
+ Used to set the maximum load that we will still respond to gitweb queries.
+ If the server load exceeds this value then gitweb will return
+ "503 Service Unavailable" error. The server load is taken to be 0
+ if gitweb cannot determine its value. Currently it works only on Linux,
+ where it uses '/proc/loadavg'; the load there is the number of active
+ tasks on the system -- processes that are actually running -- averaged
+ over the last minute.
++
+Set `$maxload` to undefined value (`undef`) to turn this feature off.
+The default value is 300.
+
+$per_request_config::
+ If this is set to code reference, it will be run once for each request.
+ You can set parts of configuration that change per session this way.
+ For example, one might use the following code in a gitweb configuration
+ file
++
+--------------------------------------------------------------------------------
+our $per_request_config = sub {
+ $ENV{GL_USER} = $cgi->remote_user || "gitweb";
+};
+--------------------------------------------------------------------------------
++
+If `$per_request_config` is not a code reference, it is interpreted as boolean
+value. If it is true gitweb will process config files once per request,
+and if it is false gitweb will process config files only once, each time it
+is executed. True by default (set to 1).
++
+*NOTE*: `$my_url`, `$my_uri`, and `$base_url` are overwritten with their default
+values before every request, so if you want to change them, be sure to set
+this variable to true or a code reference effecting the desired changes.
++
+This variable matters only when using persistent web environments that
+serve multiple requests using single gitweb instance, like mod_perl,
+FastCGI or Plackup.
+
+
+Other variables
+~~~~~~~~~~~~~~~
+Usually you should not need to change (adjust) any of configuration
+variables described below; they should be automatically set by gitweb to
+correct value.
+
+
+$version::
+ Gitweb version, set automatically when creating gitweb.cgi from
+ gitweb.perl. You might want to modify it if you are running modified
+ gitweb, for example
++
+---------------------------------------------------
+our $version .= " with caching";
+---------------------------------------------------
++
+if you run modified version of gitweb with caching support. This variable
+is purely informational, used e.g. in the "generator" meta header in HTML
+header.
+
+$my_url::
+$my_uri::
+ Full URL and absolute URL of the gitweb script;
+ in earlier versions of gitweb you might have need to set those
+ variables, but now there should be no need to do it. See
+ `$per_request_config` if you need to set them still.
+
+$base_url::
+ Base URL for relative URLs in pages generated by gitweb,
+ (e.g. `$logo`, `$favicon`, `@stylesheets` if they are relative URLs),
+ needed and used '<base href="$base_url">' only for URLs with nonempty
+ PATH_INFO. Usually gitweb sets its value correctly,
+ and there is no need to set this variable, e.g. to $my_uri or "/".
+ See `$per_request_config` if you need to override it anyway.
+
+
+CONFIGURING GITWEB FEATURES
+---------------------------
+Many gitweb features can be enabled (or disabled) and configured using the
+`%feature` hash. Names of gitweb features are keys of this hash.
+
+Each `%feature` hash element is a hash reference and has the following
+structure:
+----------------------------------------------------------------------
+"<feature_name>" => {
+ "sub" => <feature-sub (subroutine)>,
+ "override" => <allow-override (boolean)>,
+ "default" => [ <options>... ]
+},
+----------------------------------------------------------------------
+Some features cannot be overridden per project. For those
+features the structure of appropriate `%feature` hash element has a simpler
+form:
+----------------------------------------------------------------------
+"<feature_name>" => {
+ "override" => 0,
+ "default" => [ <options>... ]
+},
+----------------------------------------------------------------------
+As one can see it lacks the \'sub' element.
+
+The meaning of each part of feature configuration is described
+below:
+
+default::
+ List (array reference) of feature parameters (if there are any),
+ used also to toggle (enable or disable) given feature.
++
+Note that it is currently *always* an array reference, even if
+feature doesn't accept any configuration parameters, and \'default'
+is used only to turn it on or off. In such case you turn feature on
+by setting this element to `[1]`, and torn it off by setting it to
+`[0]`. See also the passage about the "blame" feature in the "Examples"
+section.
++
+To disable features that accept parameters (are configurable), you
+need to set this element to empty list i.e. `[]`.
+
+override::
+ If this field has a true value then the given feature is
+ overriddable, which means that it can be configured
+ (or enabled/disabled) on a per-repository basis.
++
+Usually given "<feature>" is configurable via the `gitweb.<feature>`
+config variable in the per-repository git configuration file.
++
+*Note* that no feature is overriddable by default.
+
+sub::
+ Internal detail of implementation. What is important is that
+ if this field is not present then per-repository override for
+ given feature is not supported.
++
+You wouldn't need to ever change it in gitweb config file.
+
+
+Features in `%feature`
+~~~~~~~~~~~~~~~~~~~~~~
+The gitweb features that are configurable via `%feature` hash are listed
+below. This should be a complete list, but ultimately the authoritative
+and complete list is in gitweb.cgi source code, with features described
+in the comments.
+
+blame::
+ Enable the "blame" and "blame_incremental" blob views, showing for
+ each line the last commit that modified it; see linkgit:git-blame[1].
+ This can be very CPU-intensive and is therefore disabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.blame` configuration variable (boolean).
+
+snapshot::
+ Enable and configure the "snapshot" action, which allows user to
+ download a compressed archive of any tree or commit, as produced
+ by linkgit:git-archive[1] and possibly additionally compressed.
+ This can potentially generate high traffic if you have large project.
++
+The value of \'default' is a list of names of snapshot formats,
+defined in `%known_snapshot_formats` hash, that you wish to offer.
+Supported formats include "tgz", "tbz2", "txz" (gzip/bzip2/xz
+compressed tar archive) and "zip"; please consult gitweb sources for
+a definitive list. By default only "tgz" is offered.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.blame` configuration variable, which contains
+a comma separated list of formats or "none" to disable snapshots.
+Unknown values are ignored.
+
+grep::
+ Enable grep search, which lists the files in currently selected
+ tree (directory) containing the given string; see linkgit:git-grep[1].
+ This can be potentially CPU-intensive, of course. Enabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.grep` configuration variable (boolean).
+
+pickaxe::
+ Enable the so called pickaxe search, which will list the commits
+ that introduced or removed a given string in a file. This can be
+ practical and quite faster alternative to "blame" action, but it is
+ still potentially CPU-intensive. Enabled by default.
++
+The pickaxe search is described in linkgit:git-log[1] (the
+description of `-S<string>` option, which refers to pickaxe entry in
+linkgit:gitdiffcore[7] for more details).
++
+This feature can be configured on a per-repository basis by setting
+repository's `gitweb.pickaxe` configuration variable (boolean).
+
+show-sizes::
+ Enable showing size of blobs (ordinary files) in a "tree" view, in a
+ separate column, similar to what `ls -l` does; see description of
+ `-l` option in linkgit:git-ls-tree[1] manpage. This costs a bit of
+ I/O. Enabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.showsizes` configuration variable (boolean).
+
+patches::
+ Enable and configure "patches" view, which displays list of commits in email
+ (plain text) output format; see also linkgit:git-format-patch[1].
+ The value is the maximum number of patches in a patchset generated
+ in "patches" view. Set the 'default' field to a list containing single
+ item of or to an empty list to disable patch view, or to a list
+ containing a single negative number to remove any limit.
+ Default value is 16.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.patches` configuration variable (integer).
+
+avatar::
+ Avatar support. When this feature is enabled, views such as
+ "shortlog" or "commit" will display an avatar associated with
+ the email of each committer and author.
++
+Currently available providers are *"gravatar"* and *"picon"*.
+Only one provider at a time can be selected ('default' is one element list).
+If an unknown provider is specified, the feature is disabled.
+*Note* that some providers might require extra Perl packages to be
+installed; see 'gitweb/INSTALL' for more details.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.avatar` configuration variable.
++
+See also `%avatar_size` with pixel sizes for icons and avatars
+("default" is used for one-line like "log" and "shortlog", "double"
+is used for two-line like "commit", "commitdiff" or "tag"). If the
+default font sizes or lineheights are changed (e.g. via adding extra
+CSS stylesheet in `@stylesheets`), it may be appropriate to change
+these values.
+
+highlight::
+ Server-side syntax highlight support in "blob" view. It requires
+ `$highlight_bin` program to be available (see the description of
+ this variable in the "Configuration variables" section above),
+ and therefore is disabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.highlight` configuration variable (boolean).
+
+remote_heads::
+ Enable displaying remote heads (remote-tracking branches) in the "heads"
+ list. In most cases the list of remote-tracking branches is an
+ unnecessary internal private detail, and this feature is therefore
+ disabled by default. linkgit:git-instaweb[1], which is usually used
+ to browse local repositories, enables and uses this feature.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.remote_heads` configuration variable (boolean).
+
+
+The remaining features cannot be overridden on a per project basis.
+
+search::
+ Enable text search, which will list the commits which match author,
+ committer or commit text to a given string; see the description of
+ `--author`, `--committer` and `--grep` options in linkgit:git-log[1]
+ manpage. Enabled by default.
++
+Project specific override is not supported.
+
+forks::
+ If this feature is enabled, gitweb considers projects in
+ subdirectories of project root (basename) to be forks of existing
+ projects. For each project `$projname.git`, projects in the
+ `$projname/` directory and its subdirectories will not be
+ shown in the main projects list. Instead, a \'+' mark is shown
+ next to `$projname`, which links to a "forks" view that lists all
+ the forks (all projects in `$projname/` subdirectory). Additionally
+ a "forks" view for a project is linked from project summary page.
++
+If the project list is taken from a file (`$projects_list` points to a
+file), forks are only recognized if they are listed after the main project
+in that file.
++
+Project specific override is not supported.
+
+actions::
+ Insert custom links to the action bar of all project pages. This
+ allows you to link to third-party scripts integrating into gitweb.
++
+The "default" value consists of a list of triplets in the form
+`("<label>", "<link>", "<position>")` where "position" is the label
+after which to insert the link, "link" is a format string where `%n`
+expands to the project name, `%f` to the project path within the
+filesystem (i.e. "$projectroot/$project"), `%h` to the current hash
+(\'h' gitweb parameter) and `%b` to the current hash base
+(\'hb' gitweb parameter); `%%` expands to \'%'.
++
+For example, at the time this page was written, the http://repo.or.cz[]
+git hosting site set it to the following to enable graphical log
+(using the third party tool *git-browser*):
++
+----------------------------------------------------------------------
+$feature{'actions'}{'default'} =
+ [ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')];
+----------------------------------------------------------------------
++
+This adds a link titled "graphiclog" after the "summary" link, leading to
+`git-browser` script, passing `r=<project>` as a query parameter.
++
+Project specific override is not supported.
+
+timed::
+ Enable displaying how much time and how many git commands it took to
+ generate and display each page in the page footer (at the bottom of
+ page). For example the footer might contain: "This page took 6.53325
+ seconds and 13 git commands to generate." Disabled by default.
++
+Project specific override is not supported.
+
+javascript-timezone::
+ Enable and configure the ability to change a common timezone for dates
+ in gitweb output via JavaScript. Dates in gitweb output include
+ authordate and committerdate in "commit", "commitdiff" and "log"
+ views, and taggerdate in "tag" view. Enabled by default.
++
+The value is a list of three values: a default timezone (for if the client
+hasn't selected some other timezone and saved it in a cookie), a name of cookie
+where to store selected timezone, and a CSS class used to mark up
+dates for manipulation. If you want to turn this feature off, set "default"
+to empty list: `[]`.
++
+Typical gitweb config files will only change starting (default) timezone,
+and leave other elements at their default values:
++
+---------------------------------------------------------------------------
+$feature{'javascript-timezone'}{'default'}[0] = "utc";
+---------------------------------------------------------------------------
++
+The example configuration presented here is guaranteed to be backwards
+and forward compatible.
++
+Timezone values can be "local" (for local timezone that browser uses), "utc"
+(what gitweb uses when JavaScript or this feature is disabled), or numerical
+timezones in the form of "+/-HHMM", such as "+0200".
++
+Project specific override is not supported.
+
+
+EXAMPLES
+--------
+
+To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and
+"zip" snapshots), while allowing individual projects to turn them off, put
+the following in your GITWEB_CONFIG file:
+
+ $feature{'blame'}{'default'} = [1];
+ $feature{'blame'}{'override'} = 1;
+
+ $feature{'pickaxe'}{'default'} = [1];
+ $feature{'pickaxe'}{'override'} = 1;
+
+ $feature{'snapshot'}{'default'} = ['zip', 'tgz'];
+ $feature{'snapshot'}{'override'} = 1;
+
+If you allow overriding for the snapshot feature, you can specify which
+snapshot formats are globally disabled. You can also add any command line
+options you want (such as setting the compression level). For instance, you
+can disable Zip compressed snapshots and set *gzip*(1) to run at level 6 by
+adding the following lines to your gitweb configuration file:
+
+ $known_snapshot_formats{'zip'}{'disabled'} = 1;
+ $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
+
+ENVIRONMENT
+-----------
+The location of per-instance and system-wide configuration files can be
+overridden using the following environment variables:
+
+GITWEB_CONFIG::
+ Sets location of per-instance configuration file.
+GITWEB_CONFIG_SYSTEM::
+ Sets location of fallback system-wide configuration file.
+ This file is read only if per-instance one does not exist.
+GITWEB_CONFIG_COMMON::
+ Sets location of common system-wide configuration file.
+
+
+FILES
+-----
+gitweb_config.perl::
+ This is default name of per-instance configuration file. The
+ format of this file is described above.
+/etc/gitweb.conf::
+ This is default name of fallback system-wide configuration
+ file. This file is used only if per-instance configuration
+ variable is not found.
+/etc/gitweb-common.conf::
+ This is default name of common system-wide configuration
+ file.

+NAME
+----
+gitweb - Git web interface (web frontend to Git repositories)
+
+SYNOPSIS
+--------
+To get started with gitweb, run linkgit:git-instaweb[1] from a git repository.
+This would configure and start your web server, and run web browser pointing to
+gitweb.
+
+
+DESCRIPTION
+-----------
+Gitweb provides a web interface to git repositories. It's features include:
+
+* Viewing multiple Git repositories with common root.
+* Browsing every revision of the repository.
+* Viewing the contents of files in the repository at any revision.
+* Viewing the revision log of branches, history of files and directories,
+ see what was changed when, by who.
+* Viewing the blame/annotation details of any file (if enabled).
+* Generating RSS and Atom feeds of commits, for any branch.
+ The feeds are auto-discoverable in modern web browsers.
+* Viewing everything that was changed in a revision, and step through
+ revisions one at a time, viewing the history of the repository.
+* Finding commits which commit messages matches given search term.
+
+See http://git.kernel.org/?p=git/git.git;a=tree;f=gitweb[] or
+http://repo.or.cz/w/git.git/tree/HEAD:/gitweb/[] for gitweb source code,
+browsed using gitweb itself.
+
+
+CONFIGURATION
+-------------
+Various aspects of gitweb's behavior can be controlled through the configuration
+file 'gitweb_config.perl' or '/etc/gitweb.conf'. See the linkgit:gitweb.conf[5]
+for details.
+
+Repositories
+~~~~~~~~~~~~
+Gitweb can show information from one or more Git repositories. These
+repositories have to be all on local filesystem, and have to share common
+repository root, i.e. be all under a single parent repository (but see also
+"Advanced web server setup" section, "Webserver configuration with multiple
+projects' root" subsection).
+
+-----------------------------------------------------------------------
+our $projectroot = '/path/to/parent/directory';
+-----------------------------------------------------------------------
+
+The default value for `$projectroot` is '/pub/git'. You can change it during
+building gitweb via `GITWEB_PROJECTROOT` build configuration variable.
+
+By default all git repositories under `$projectroot` are visible and available
+to gitweb. The list of projects is generated by default by scanning the
+`$projectroot` directory for git repositories (for object databases to be
+more exact; gitweb is not interested in a working area, and is best suited
+to showing "bare" repositories).
+
+The name of repository in gitweb is path to it's `$GIT_DIR` (it's object
+database) relative to `$projectroot`. Therefore the repository $repo can be
+found at "$projectroot/$repo".
+
+
+Projects list file format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Instead of having gitweb find repositories by scanning filesystem
+starting from $projectroot, you can provide a pre-generated list of
+visible projects by setting `$projects_list` to point to a plain text
+file with a list of projects (with some additional info).
+
+This file uses the following format:
+
+* One record (for project / repository) per line; does not support line
+continuation (newline escaping).
+
+* Leading and trailing whitespace are ignored.
+
+* Whitespace separated fields; any run of whitespace can be used as field
+separator (rules for Perl's "`split(" ", $line)`").
+
+* Fields use modified URI encoding, defined in RFC 3986, section 2.1
+(Percent-Encoding), or rather "Query string encoding" (see
+link:http://en.wikipedia.org/wiki/Query_string#URL_encoding[]), the difference
+being that SP (" ") can be encoded as "{plus}" (and therefore "{plus}" has to be
+also percent-encoded).
++
+Reserved characters are: "%" (used for encoding), "{plus}" (can be used to
+encode SPACE), all whitespace characters as defined in Perl, including SP,
+TAB and LF, (used to separate fields in a record).
+
+* Currently recognized fields are:
+<repository path>::
+ path to repository GIT_DIR, relative to `$projectroot`
+<repository owner>::
+ displayed as repository owner, preferably full name, or email,
+ or both
+
+You can generate the projects list index file using the project_index action
+(the 'TXT' link on projects list page) directly from gitweb; see also
+"Generating projects list using gitweb" section below.
+
+Example contents:
+-----------------------------------------------------------------------
+foo.git Joe+R+Hacker+<joe@example.com>
+foo/bar.git O+W+Ner+<owner@example.org>
+-----------------------------------------------------------------------
+
+
+By default this file controls only which projects are *visible* on projects
+list page (note that entries that do not point to correctly recognized git
+repositories won't be displayed by gitweb). Even if a project is not
+visible on projects list page, you can view it nevertheless by hand-crafting
+a gitweb URL. By setting `$strict_export` configuration variable (see
+linkgit:gitweb.conf[5]) to true value you can allow viewing only of
+repositories also shown on the overview page (i.e. only projects explicitly
+listed in projects list file will be accessible).
+
+
+Generating projects list using gitweb
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We assume that GITWEB_CONFIG has its default Makefile value, namely
+'gitweb_config.perl'. Put the following in 'gitweb_make_index.perl' file:
+----------------------------------------------------------------------------
+read_config_file("gitweb_config.perl");
+$projects_list = $projectroot;
+----------------------------------------------------------------------------
+
+Then create the following script to get list of project in the format
+suitable for GITWEB_LIST build configuration variable (or
+`$projects_list` variable in gitweb config):
+
+----------------------------------------------------------------------------
+#!/bin/sh
+
+export GITWEB_CONFIG="gitweb_make_index.perl"
+export GATEWAY_INTERFACE="CGI/1.1"
+export HTTP_ACCEPT="*/*"
+export REQUEST_METHOD="GET"
+export QUERY_STRING="a=project_index"
+
+perl -- /var/www/cgi-bin/gitweb.cgi
+----------------------------------------------------------------------------
+
+Run this script and save its output to a file. This file could then be used
+as projects list file, which means that you can set `$projects_list` to its
+filename.
+
+
+Controlling access to git repositories
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+By default all git repositories under `$projectroot` are visible and
+available to gitweb. You can however configure how gitweb controls access
+to repositories.
+
+* As described in "Projects list file format" section, you can control which
+projects are *visible* by selectively including repositories in projects
+list file, and setting `$projects_list` gitweb configuration variable to
+point to it. With `$strict_export` set, projects list file can be used to
+control which repositories are *available* as well.
+
+* You can configure gitweb to only list and allow viewing of the explicitly
+exported repositories, via `$export_ok` variable in gitweb config file; see
+linkgit:gitweb.conf[5] manpage. If it evaluates to true, gitweb shows
+repositories only if this file named by `$export_ok` exists in its object
+database (if directory has the magic file named `$export_ok`).
++
+For example linkgit:git-daemon[1] by default (unless `--export-all` option
+is used) allows pulling only for those repositories that have
+'git-daemon-export-ok' file. Adding
++
+--------------------------------------------------------------------------
+our $export_ok = "git-daemon-export-ok";
+--------------------------------------------------------------------------
++
+makes gitweb show and allow access only to those repositories that can be
+fetched from via `git://` protocol.
+
+* Finally, it is possible to specify an arbitrary perl subroutine that will
+be called for each repository to determine if it can be exported. The
+subroutine receives an absolute path to the project (repository) as its only
+parameter (i.e. "$projectroot/$project").
++
+For example, if you use mod_perl to run the script, and have dumb
+HTTP protocol authentication configured for your repositories, you
+can use the following hook to allow access only if the user is
+authorized to read the files:
++
+--------------------------------------------------------------------------
+$export_auth_hook = sub {
+ use Apache2::SubRequest ();
+ use Apache2::Const -compile => qw(HTTP_OK);
+ my $path = "$_[0]/HEAD";
+ my $r = Apache2::RequestUtil->request;
+ my $sub = $r->lookup_file($path);
+ return $sub->filename eq $path
+ && $sub->status == Apache2::Const::HTTP_OK;
+};
+--------------------------------------------------------------------------
+
+
+Per-repository gitweb configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can configure individual repositories shown in gitweb by creating file
+in the 'GIT_DIR' of git repository, or by setting some repo configuration
+variable (in 'GIT_DIR/config', see linkgit:git-config[1]).
+
+You can use the following files in repository:
+
+README.html::
+ A html file (HTML fragment) which is included on the gitweb project
+ "summary" page inside `<div>` block element. You can use it for longer
+ description of a project, to provide links (for example to project's
+ homepage), etc. This is recognized only if XSS prevention is off
+ (`$prevent_xss` is false, see linkgit:gitweb.conf[5]); a way to include
+ a README safely when XSS prevention is on may be worked out in the
+ future.
+
+description (or `gitweb.description`)::
+ Short (shortened to `$projects_list_description_width` in the projects
+ list page, which is 25 characters by default; see
+ linkgit:gitweb.conf[5]) single line description of a project (of a
+ repository). Plain text file; HTML will be escaped. By default set to
++
+-------------------------------------------------------------------------------
+Unnamed repository; edit this file to name it for gitweb.
+-------------------------------------------------------------------------------
++
+from the template during repository creation, usually installed in
+'/usr/share/git-core/templates/'. You can use the `gitweb.description` repo
+configuration variable, but the file takes precedence.
+
+category (or `gitweb.category`)::
+ Singe line category of a project, used to group projects if
+ `$projects_list_group_categories` is enabled. By default (file and
+ configuration variable absent), uncategorized projects are put in the
+ `$project_list_default_category` category. You can use the
+ `gitweb.category` repo configuration variable, but the file takes
+ precedence.
++
+The configuration variables `$projects_list_group_categories` and
+`$project_list_default_category` are described in linkgit:gitweb.conf[5]
+
+cloneurl (or multiple-valued `gitweb.url`)::
+ File with repository URL (used for clone and fetch), one per line.
+ Displayed in the project summary page. You can use multiple-valued
+ `gitweb.url` repository configuration variable for that, but the file
+ takes precedence.
++
+This is per-repository enhancement / version of global prefix-based
+`@git_base_url_list` gitweb configuration variable (see
+linkgit:gitweb.conf[5]).
+
+gitweb.owner::
+ You can use the `gitweb.owner` repository configuration variable to set
+ repository's owner. It is displayed in the project list and summary
+ page.
++
+If it's not set, filesystem directory's owner is used (via GECOS field,
+i.e. real name field from *getpwuid*(3)) if `$projects_list` is unset
+(gitweb scans `$projectroot` for repositories); if `$projects_list`
+points to file with list of repositories, then project owner defaults to
+value from this file for given repository.
+
+various `gitweb.*` config variables (in config)::
+ Read description of `%feature` hash for detailed list, and descriptions.
+ See also "Configuring gitweb features" section in linkgit:gitweb.conf[5]
+
+
+ACTIONS, AND URLS
+-----------------
+Gitweb can use path_info (component) based URLs, or it can pass all necessary
+information via query parameters. The typical gitweb URLs are broken down in to
+five components:
+
+-----------------------------------------------------------------------
+.../gitweb.cgi/<repo>/<action>/<revision>:/<path>?<arguments>
+-----------------------------------------------------------------------
+
+repo::
+ The repository the action will be performed on.
++
+All actions except for those that list all available projects,
+in whatever form, require this parameter.
+
+action::
+ The action that will be run. Defaults to 'projects_list' if repo
+ is not set, and to 'summary' otherwise.
+
+revision::
+ Revision shown. Defaults to HEAD.
+
+path::
+ The path within the <repository> that the action is performed on,
+ for those actions that require it.
+
+arguments::
+ Any arguments that control the behaviour of the action.
+
+Some actions require or allow to specify two revisions, and sometimes even two
+pathnames. In most general form such path_info (component) based gitweb URL
+looks like this:
+
+-----------------------------------------------------------------------
+.../gitweb.cgi/<repo>/<action>/<revision_from>:/<path_from>..<revision_to>:/<path_to>?<arguments>
+-----------------------------------------------------------------------
+
+
+Each action is implemented as a subroutine, and must be present in %actions
+hash. Some actions are disabled by default, and must be turned on via feature
+mechanism. For example to enable 'blame' view add the following to gitweb
+configuration file:
+
+-----------------------------------------------------------------------
+$feature{'blame'}{'default'} = [1];
+-----------------------------------------------------------------------
+
+
+Actions:
+~~~~~~~~
+The standard actions are:
+
+project_list::
+ Lists the available Git repositories. This is the default command if no
+ repository is specified in the URL.
+
+summary::
+ Displays summary about given repository. This is the default command if
+ no action is specified in URL, and only repository is specified.
+
+heads::
+remotes::
+ Lists all local or all remote-tracking branches in given repository.
++
+The latter is not available by default, unless configured.
+
+tags::
+ List all tags (lightweight and annotated) in given repository.
+
+blob::
+tree::
+ Shows the files and directories in a given repository path, at given
+ revision. This is default command if no action is specified in the URL,
+ and path is given.
+
+blob_plain::
+ Returns the raw data for the file in given repository, at given path and
+ revision. Links to this action are marked 'raw'.
+
+blobdiff::
+ Shows the difference between two revisions of the same file.
+
+blame::
+blame_incremental::
+ Shows the blame (also called annotation) information for a file. On a
+ per line basis it shows the revision in which that line was last changed
+ and the user that committed the change. The incremental version (which
+ if configured is used automatically when JavaScript is enabled) uses
+ Ajax to incrementally add blame info to the contents of given file.
++
+This action is disabled by default for performance reasons.
+
+commit::
+commitdiff::
+ Shows information about a specific commit in a repository. The 'commit'
+ view shows information about commit in more detail, the 'commitdiff'
+ action shows changeset for given commit.
+
+patch::
+ Returns the commit in plain text mail format, suitable for applying with
+ linkgit:git-am[1].
+
+tag::
+ Display specific annotated tag (tag object).
+
+log::
+shortlog::
+ Shows log information (commit message or just commit subject) for a

+WEBSERVER CONFIGURATION
+-----------------------
+This section explains how to configure some common webservers to run gitweb. In
+all cases, `/path/to/gitweb` in the examples is the directory you ran installed
+gitweb in, and contains `gitweb_config.perl`.
+
+If you've configured a web server that isn't listed here for gitweb, please send
+in the instructions so they can be included in a future release.
+
+Apache as CGI
+~~~~~~~~~~~~~
+Apache must be configured to support CGI scripts in the directory in
+which gitweb is installed. Let's assume that it is '/var/www/cgi-bin'
+directory.
+
+-----------------------------------------------------------------------
+ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
+
+<Directory "/var/www/cgi-bin">
+ Options Indexes FollowSymlinks ExecCGI
+ AllowOverride None
+ Order allow,deny
+ Allow from all
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+ http://server/cgi-bin/gitweb.cgi
+
+Apache with mod_perl, via ModPerl::Registry
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can use mod_perl with gitweb. You must install Apache::Registry
+(for mod_perl 1.x) or ModPerl::Registry (for mod_perl 2.x) to enable
+this support.
+
+Assuming that gitweb is installed to '/var/www/perl', the following
+Apache configuration (for mod_perl 2.x) is suitable.
+
+-----------------------------------------------------------------------
+Alias /perl "/var/www/perl"
+
+<Directory "/var/www/perl">
+ SetHandler perl-script
+ PerlResponseHandler ModPerl::Registry
+ PerlOptions +ParseHeaders
+ Options Indexes FollowSymlinks +ExecCGI
+ AllowOverride None
+ Order allow,deny
+ Allow from all
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+ http://server/perl/gitweb.cgi
+
+Apache with FastCGI
+~~~~~~~~~~~~~~~~~~~
+Gitweb works with Apache and FastCGI. First you need to rename, copy
+or symlink gitweb.cgi to gitweb.fcgi. Let's assume that gitweb is
+installed in '/usr/share/gitweb' directory. The following Apache
+configuration is suitable (UNTESTED!)
+
+-----------------------------------------------------------------------
+FastCgiServer /usr/share/gitweb/gitweb.cgi
+ScriptAlias /gitweb /usr/share/gitweb/gitweb.cgi
+
+Alias /gitweb/static /usr/share/gitweb/static
+<Directory /usr/share/gitweb/static>
+ SetHandler default-handler
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+ http://server/gitweb
+
+
+ADVANCED WEB SERVER SETUP
+-------------------------
+All of those examples use request rewriting, and need `mod_rewrite`
+(or equivalent; examples below are written for Apache).
+
+Single URL for gitweb and for fetching
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you want to have one URL for both gitweb and your `http://`
+repositories, you can configure Apache like this:
+
+-----------------------------------------------------------------------
+<VirtualHost *:80>
+ ServerName git.example.org
+ DocumentRoot /pub/git
+ SetEnv GITWEB_CONFIG /etc/gitweb.conf
+
+ # turning on mod rewrite
+ RewriteEngine on
+
+ # make the front page an internal rewrite to the gitweb script
+ RewriteRule ^/$ /cgi-bin/gitweb.cgi
+
+ # make access for "dumb clients" work
+ RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \
+ /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT]
+</VirtualHost>
+-----------------------------------------------------------------------
+
+The above configuration expects your public repositories to live under
+'/pub/git' and will serve them as `http://git.domain.org/dir-under-pub-git`,
+both as cloneable GIT URL and as browseable gitweb interface. If you then
+start your linkgit:git-daemon[1] with `--base-path=/pub/git --export-all`
+then you can even use the `git://` URL with exactly the same path.
+
+Setting the environment variable `GITWEB_CONFIG` will tell gitweb to use the
+named file (i.e. in this example '/etc/gitweb.conf') as a configuration for
+gitweb. You don't really need it in above example; it is required only if
+your configuration file is in different place than built-in (during
+compiling gitweb) 'gitweb_config.perl' or '/etc/gitweb.conf'. See
+linkgit:gitweb.conf[5] for details, especially information about precedence
+rules.
+
+If you use the rewrite rules from the example you *might* also need
+something like the following in your gitweb configuration file
+('/etc/gitweb.conf' following example):
+----------------------------------------------------------------------------
+@stylesheets = ("/some/absolute/path/gitweb.css");
+$my_uri = "/";
+$home_link = "/";
+$per_request_config = 1;
+----------------------------------------------------------------------------
+Nowadays though gitweb should create HTML base tag when needed (to set base
+URI for relative links), so it should work automatically.
+
+
+Webserver configuration with multiple projects' root
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you want to use gitweb with several project roots you can edit your
+Apache virtual host and gitweb configuration files in the following way.
+
+The virtual host configuration (in Apache configuration file) should look
+like this:
+--------------------------------------------------------------------------
+<VirtualHost *:80>
+ ServerName git.example.org
+ DocumentRoot /pub/git
+ SetEnv GITWEB_CONFIG /etc/gitweb.conf
+
+ # turning on mod rewrite
+ RewriteEngine on
+
+ # make the front page an internal rewrite to the gitweb script
+ RewriteRule ^/$ /cgi-bin/gitweb.cgi [QSA,L,PT]
+
+ # look for a public_git folder in unix users' home
+ # http://git.example.org/~<user>/
+ RewriteRule ^/\~([^\/]+)(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+ [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+ # http://git.example.org/+<user>/
+ #RewriteRule ^/\+([^\/]+)(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+ [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+ # http://git.example.org/user/<user>/
+ #RewriteRule ^/user/([^\/]+)/(gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+ [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+ # defined list of project roots
+ RewriteRule ^/scm(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+ [QSA,E=GITWEB_PROJECTROOT:/pub/scm/,L,PT]
+ RewriteRule ^/var(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+ [QSA,E=GITWEB_PROJECTROOT:/var/git/,L,PT]
+
+ # make access for "dumb clients" work
+ RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \
+ /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT]
+</VirtualHost>
+--------------------------------------------------------------------------
+
+Here actual project root is passed to gitweb via `GITWEB_PROJECT_ROOT`
+environment variable from a web server, so you need to put the following
+line in gitweb configuration file ('/etc/gitweb.conf' in above example):
+--------------------------------------------------------------------------
+$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git";
+--------------------------------------------------------------------------
+*Note* that this requires to be set for each request, so either
+`$per_request_config` must be false, or the above must be put in code
+referenced by `$per_request_config`;
+
+These configurations enable two things. First, each unix user (`<user>`) of
+the server will be able to browse through gitweb git repositories found in
+'~/public_git/' with the following url:
+
+ http://git.example.org/~<user>/
+
+If you do not want this feature on your server just remove the second
+rewrite rule.
+
+If you already use `mod_userdir` in your virtual host or you don't want to
+use the \'~' as first character, just comment or remove the second rewrite
+rule, and uncomment one of the following according to what you want.
+
+Second, repositories found in '/pub/scm/' and '/var/git/' will be accessible
+through `http://git.example.org/scm/` and `http://git.example.org/var/`.
+You can add as many project roots as you want by adding rewrite rules like
+the third and the fourth.
+
+
+PATH_INFO usage
+~~~~~~~~~~~~~~~
+If you enable PATH_INFO usage in gitweb by putting
+----------------------------------------------------------------------------
+$feature{'pathinfo'}{'default'} = [1];
+----------------------------------------------------------------------------
+in your gitweb configuration file, it is possible to set up your server so
+that it consumes and produces URLs in the form
+
+ http://git.example.com/project.git/shortlog/sometag
+
+i.e. without 'gitweb.cgi' part, by using a configuration such as the
+following. This configuration assumes that '/var/www/gitweb' is the
+DocumentRoot of your webserver, contains the gitweb.cgi script and
+complementary static files (stylesheet, favicon, JavaScript):
+
+----------------------------------------------------------------------------
+<VirtualHost *:80>
+ ServerAlias git.example.com
+
+ DocumentRoot /var/www/gitweb
+
+ <Directory /var/www/gitweb>
+ Options ExecCGI
+ AddHandler cgi-script cgi
+
+ DirectoryIndex gitweb.cgi
+
+ RewriteEngine On
+ RewriteCond %{REQUEST_FILENAME} !-f
+ RewriteCond %{REQUEST_FILENAME} !-d
+ RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+ </Directory>
+</VirtualHost>
+----------------------------------------------------------------------------
+The rewrite rule guarantees that existing static files will be properly
+served, whereas any other URL will be passed to gitweb as PATH_INFO
+parameter.
+
+*Notice* that in this case you don't need special settings for
+`@stylesheets`, `$my_uri` and `$home_link`, but you lose "dumb client"
+access to your project .git dirs (described in "Single URL for gitweb and
+for fetching" section). A possible workaround for the latter is the
+following: in your project root dir (e.g. '/pub/git') have the projects
+named *without* a .git extension (e.g. '/pub/git/project' instead of
+'/pub/git/project.git') and configure Apache as follows:
+----------------------------------------------------------------------------
+<VirtualHost *:80>
+ ServerAlias git.example.com
+
+ DocumentRoot /var/www/gitweb
+
+ AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3
+ <Directory /var/www/gitweb>
+ Options ExecCGI
+ AddHandler cgi-script cgi
+
+ DirectoryIndex gitweb.cgi
+
+ RewriteEngine On
+ RewriteCond %{REQUEST_FILENAME} !-f
+ RewriteCond %{REQUEST_FILENAME} !-d
+ RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+ </Directory>
+</VirtualHost>
+----------------------------------------------------------------------------
+
+The additional AliasMatch makes it so that
+
+ http://git.example.com/project.git
+
+will give raw access to the project's git dir (so that the project can be
+cloned), while
+
+ http://git.example.com/project
+
+will provide human-friendly gitweb access.
+
+This solution is not 100% bulletproof, in the sense that if some project has
+a named ref (branch, tag) starting with 'git/', then paths such as
+
+ http://git.example.com/project/command/abranch..git/abranch
+
+will fail with a 404 error.

+ Pattern used to specify paths.
++
+Pathspecs are used on the command line of "git ls-files", "git
+ls-tree", "git add", "git grep", "git diff", "git checkout",
+and many other commands to
+limit the scope of operations to some subset of the tree or
+worktree. See the documentation of each command for whether
+paths are relative to the current directory or toplevel. The
+pathspec syntax is as follows:
+
+* any path matches itself
+* the pathspec up to the last slash represents a
+ directory prefix. The scope of that pathspec is
+ limited to that subtree.
+* the rest of the pathspec is a pattern for the remainder
+ of the pathname. Paths relative to the directory
+ prefix will be matched against that pattern using fnmatch(3);
+ in particular, '*' and '?' _can_ match directory separators.
++
+For example, Documentation/*.jpg will match all .jpg files
+in the Documentation subtree,
+including Documentation/chapter_1/figure_1.jpg.
+
++
+A pathspec that begins with a colon `:` has special meaning. In the
+short form, the leading colon `:` is followed by zero or more "magic
+signature" letters (which optionally is terminated by another colon `:`),
+and the remainder is the pattern to match against the path. The optional
+colon that terminates the "magic signature" can be omitted if the pattern
+begins with a character that cannot be a "magic signature" and is not a
+colon.
++
+In the long form, the leading colon `:` is followed by a open
+parenthesis `(`, a comma-separated list of zero or more "magic words",
+and a close parentheses `)`, and the remainder is the pattern to match
+against the path.
++
+The "magic signature" consists of an ASCII symbol that is not
+alphanumeric.
++
+--
+top `/`;;
+ The magic word `top` (mnemonic: `/`) makes the pattern match
+ from the root of the working tree, even when you are running
+ the command from inside a subdirectory.
+--
++
+Currently only the slash `/` is recognized as the "magic signature",
+but it is envisioned that we will support more types of magic in later
+versions of git.
++
+A pathspec with only a colon means "there is no pathspec". This form
+should not be combined with other pathspec.

ready yet, and I really need to undo _all_ of the merge"). So then you
really should revert the merge, but when you want to re-do the merge, you
now need to do it by reverting the revert.
+
+ADDENDUM
+
+Sometimes you have to rewrite one of a topic branch's commits *and* you can't
+change the topic's branching-off point. Consider the following situation:
+
+ P---o---o---M---x---x---W---x
+ \ /
+ A---B---C
+
+where commit W reverted commit M because it turned out that commit B was wrong
+and needs to be rewritten, but you need the rewritten topic to still branch
+from commit P (perhaps P is a branching-off point for yet another branch, and
+you want be able to merge the topic into both branches).
+
+The natural thing to do in this case is to checkout the A-B-C branch and use
+"rebase -i P" to change commit B. However this does not rewrite commit A,
+because "rebase -i" by default fast-forwards over any initial commits selected
+with the "pick" command. So you end up with this:
+
+ P---o---o---M---x---x---W---x
+ \ /
+ A---B---C <-- old branch
+ \
+ B'---C' <-- naively rewritten branch
+
+To merge A-B'-C' into the mainline branch you would still have to first revert
+commit W in order to pick up the changes in A, but then it's likely that the
+changes in B' will conflict with the original B changes re-introduced by the
+reversion of W.
+
+However, you can avoid these problems if you recreate the entire branch,
+including commit A:
+
+ A'---B'---C' <-- completely rewritten branch
+ /
+ P---o---o---M---x---x---W---x
+ \ /
+ A---B---C
+
+You can merge A'-B'-C' into the mainline branch without worrying about first
+reverting W. Mainline's history would look like this:
+
+ A'---B'---C'------------------
+ / \
+ P---o---o---M---x---x---W---x---M2
+ \ /
+ A---B---C
+
+But if you don't actually need to change commit A, then you need some way to
+recreate it as a new commit with the same changes in it. The rebase command's
+--no-ff option provides a way to do this:
+
+ $ git rebase [-i] --no-ff P
+
+The --no-ff option creates a new branch A'-B'-C' with all-new commits (all the
+SHA IDs will be different) even if in the interactive case you only actually
+modify commit B. You can then merge this new branch directly into the mainline
+branch and be sure you'll get all of the branch's changes.
+
+You can also use --no-ff in cases where you just add extra commits to the topic
+to fix it up. Let's revisit the situation discussed at the start of this howto:
+
+ P---o---o---M---x---x---W---x
+ \ /
+ A---B---C----------------D---E <-- fixed-up topic branch
+
+At this point, you can use --no-ff to recreate the topic branch:
+
+ $ git checkout E
+ $ git rebase --no-ff P
+
+yielding
+
+ A'---B'---C'------------D'---E' <-- recreated topic branch
+ /
+ P---o---o---M---x---x---W---x
+ \ /
+ A---B---C----------------D---E
+
+You can merge the recreated branch into the mainline without reverting commit W,
+and mainline's history will look like this:
+
+ A'---B'---C'------------D'---E'
+ / \
+ P---o---o---M---x---x---W---x---M2

MERGE STRATEGIES

Additionally this can detect and handle merges involving

pulling or merging one branch.
++
+The 'recursive' strategy can take the following options:

+ This option forces conflicting hunks to be auto-resolved cleanly by
+ favoring 'our' version. Changes from the other tree that do not
+ conflict with our side are reflected to the merge result.
++
+This should not be confused with the 'ours' merge strategy, which does not
+even look at what the other tree contains at all. It discards everything
+the other tree did, declaring 'our' history contains all that happened in it.
+
+theirs;;
+ This is opposite of 'ours'.
+
+patience;;
+ With this option, 'merge-recursive' spends a little extra time

+ matching lines (e.g., braces from distinct functions). Use
+ this when the branches to be merged have diverged wildly.
+ See also linkgit:git-diff[1] `--patience`.

+ignore-space-at-eol;;
+ Treats lines with the indicated type of whitespace change as

+* If 'our' version introduces whitespace changes but 'their'
+ version includes a substantial change, 'their' version is used;
+* Otherwise, the merge proceeds in the usual way.
+
+renormalize;;
+ This runs a virtual check-out and check-in of all three stages
+ of a file when resolving a three-way merge. This option is
+ meant to be used when merging branches with different clean

+SPECIFYING REVISIONS
+--------------------
+
+A revision parameter '<rev>' typically, but not necessarily, names a
+commit object. It uses what is called an 'extended SHA1'
+syntax. Here are various ways to spell object names. The
+ones listed near the end of this list name trees and
+blobs contained in a commit.
+
+'<sha1>', e.g. 'dae86e1950b1277e545cee180551750029cfe735', 'dae86e'::
+ The full SHA1 object name (40-byte hexadecimal string), or
+ a leading substring that is unique within the repository.
+ E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
+ name the same commit object if there is no other object in
+ your repository whose object name starts with dae86e.
+
+'<describeOutput>', e.g. 'v1.7.4.2-679-g3bee7fb'::
+ Output from `git describe`; i.e. a closest tag, optionally
+ followed by a dash and a number of commits, followed by a dash, a
+ 'g', and an abbreviated object name.
+
+'<refname>', e.g. 'master', 'heads/master', 'refs/heads/master'::
+ A symbolic ref name. E.g. 'master' typically means the commit
+ object referenced by 'refs/heads/master'. If you
+ happen to have both 'heads/master' and 'tags/master', you can
+ explicitly say 'heads/master' to tell git which one you mean.
+ When ambiguous, a '<name>' is disambiguated by taking the
+ first match in the following rules:
+
+ . If '$GIT_DIR/<name>' exists, that is what you mean (this is usually
+ useful only for 'HEAD', 'FETCH_HEAD', 'ORIG_HEAD', 'MERGE_HEAD'
+ and 'CHERRY_PICK_HEAD');
+
+ . otherwise, 'refs/<name>' if it exists;
+
+ . otherwise, 'refs/tags/<refname>' if it exists;
+
+ . otherwise, 'refs/heads/<name>' if it exists;
+
+ . otherwise, 'refs/remotes/<name>' if it exists;
+
+ . otherwise, 'refs/remotes/<name>/HEAD' if it exists.
++
+'HEAD' names the commit on which you based the changes in the working tree.
+'FETCH_HEAD' records the branch which you fetched from a remote repository
+with your last `git fetch` invocation.
+'ORIG_HEAD' is created by commands that move your 'HEAD' in a drastic
+way, to record the position of the 'HEAD' before their operation, so that
+you can easily change the tip of the branch back to the state before you ran
+them.
+'MERGE_HEAD' records the commit(s) which you are merging into your branch
+when you run `git merge`.
+'CHERRY_PICK_HEAD' records the commit which you are cherry-picking
+when you run `git cherry-pick`.
++
+Note that any of the 'refs/*' cases above may come either from
+the '$GIT_DIR/refs' directory or from the '$GIT_DIR/packed-refs' file.
+
+'<refname>@\{<date>\}', e.g. 'master@\{yesterday\}', 'HEAD@\{5 minutes ago\}'::
+ A ref followed by the suffix '@' with a date specification
+ enclosed in a brace
+ pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
+ second ago\}' or '\{1979-02-26 18:30:00\}') specifies the value
+ of the ref at a prior point in time. This suffix may only be
+ used immediately following a ref name and the ref must have an
+ existing log ('$GIT_DIR/logs/<ref>'). Note that this looks up the state
+ of your *local* ref at a given time; e.g., what was in your local
+ 'master' branch last week. If you want to look at commits made during
+ certain times, see '--since' and '--until'.
+
+'<refname>@\{<n>\}', e.g. 'master@\{1\}'::
+ A ref followed by the suffix '@' with an ordinal specification
+ enclosed in a brace pair (e.g. '\{1\}', '\{15\}') specifies
+ the n-th prior value of that ref. For example 'master@\{1\}'
+ is the immediate prior value of 'master' while 'master@\{5\}'
+ is the 5th prior value of 'master'. This suffix may only be used
+ immediately following a ref name and the ref must have an existing
+ log ('$GIT_DIR/logs/<refname>').
+
+'@\{<n>\}', e.g. '@\{1\}'::
+ You can use the '@' construct with an empty ref part to get at a
+ reflog entry of the current branch. For example, if you are on
+ branch 'blabla' then '@\{1\}' means the same as 'blabla@\{1\}'.
+
+'@\{-<n>\}', e.g. '@\{-1\}'::
+ The construct '@\{-<n>\}' means the <n>th branch checked out
+ before the current one.
+
+'<refname>@\{upstream\}', e.g. 'master@\{upstream\}', '@\{u\}'::
+ The suffix '@\{upstream\}' to a ref (short form '<refname>@\{u\}') refers to
+ the branch the ref is set to build on top of. A missing ref defaults
+ to the current branch.
+
+'<rev>{caret}', e.g. 'HEAD{caret}, v1.5.1{caret}0'::
+ A suffix '{caret}' to a revision parameter means the first parent of
+ that commit object. '{caret}<n>' means the <n>th parent (i.e.
+ '<rev>{caret}'
+ is equivalent to '<rev>{caret}1'). As a special rule,
+ '<rev>{caret}0' means the commit itself and is used when '<rev>' is the
+ object name of a tag object that refers to a commit object.
+
+'<rev>{tilde}<n>', e.g. 'master{tilde}3'::
+ A suffix '{tilde}<n>' to a revision parameter means the commit
+ object that is the <n>th generation grand-parent of the named
+ commit object, following only the first parents. I.e. '<rev>{tilde}3' is
+ equivalent to '<rev>{caret}{caret}{caret}' which is equivalent to
+ '<rev>{caret}1{caret}1{caret}1'. See below for an illustration of
+ the usage of this form.
+
+'<rev>{caret}\{<type>\}', e.g. 'v0.99.8{caret}\{commit\}'::
+ A suffix '{caret}' followed by an object type name enclosed in
+ brace pair means the object
+ could be a tag, and dereference the tag recursively until an
+ object of that type is found or the object cannot be
+ dereferenced anymore (in which case, barf). '<rev>{caret}0'
+ is a short-hand for '<rev>{caret}\{commit\}'.
+
+'<rev>{caret}\{\}', e.g. 'v0.99.8{caret}\{\}'::
+ A suffix '{caret}' followed by an empty brace pair
+ means the object could be a tag,
+ and dereference the tag recursively until a non-tag object is
+ found.
+
+'<rev>{caret}\{/<text>\}', e.g. 'HEAD^{/fix nasty bug}'::
+ A suffix '{caret}' to a revision parameter, followed by a brace
+ pair that contains a text led by a slash,
+ is the same as the ':/fix nasty bug' syntax below except that
+ it returns the youngest matching commit which is reachable from
+ the '<rev>' before '{caret}'.
+
+':/<text>', e.g. ':/fix nasty bug'::
+ A colon, followed by a slash, followed by a text, names
+ a commit whose commit message matches the specified regular expression.
+ This name returns the youngest matching commit which is
+ reachable from any ref. If the commit message starts with a
+ '!' you have to repeat that; the special sequence ':/!',
+ followed by something else than '!', is reserved for now.
+ The regular expression can match any part of the commit message. To
+ match messages starting with a string, one can use e.g. ':/^foo'.
+
+'<rev>:<path>', e.g. 'HEAD:README', ':README', 'master:./README'::
+ A suffix ':' followed by a path names the blob or tree
+ at the given path in the tree-ish object named by the part
+ before the colon.
+ ':path' (with an empty part before the colon)
+ is a special case of the syntax described next: content
+ recorded in the index at the given path.
+ A path starting with './' or '../' is relative to the current working directory.
+ The given path will be converted to be relative to the working tree's root directory.
+ This is most useful to address a blob or tree from a commit or tree that has
+ the same tree structure as the working tree.
+
+':<n>:<path>', e.g. ':0:README', ':README'::
+ A colon, optionally followed by a stage number (0 to 3) and a
+ colon, followed by a path, names a blob object in the
+ index at the given path. A missing stage number (and the colon
+ that follows it) names a stage 0 entry. During a merge, stage
+ 1 is the common ancestor, stage 2 is the target branch's version
+ (typically the current branch), and stage 3 is the version from
+ the branch which is being merged.
+
+Here is an illustration, by Jon Loeliger. Both commit nodes B
+and C are parents of commit node A. Parent commits are ordered
+left-to-right.

+
+SPECIFYING RANGES
+-----------------
+
+History traversing commands such as `git log` operate on a set
+of commits, not just a single commit. To these commands,
+specifying a single revision with the notation described in the
+previous section means the set of commits reachable from that
+commit, following the commit ancestry chain.
+
+To exclude commits reachable from a commit, a prefix '{caret}'
+notation is used. E.g. '{caret}r1 r2' means commits reachable
+from 'r2' but exclude the ones reachable from 'r1'.
+
+This set operation appears so often that there is a shorthand
+for it. When you have two commits 'r1' and 'r2' (named according
+to the syntax explained in SPECIFYING REVISIONS above), you can ask
+for commits that are reachable from r2 excluding those that are reachable
+from r1 by '{caret}r1 r2' and it can be written as 'r1..r2'.
+
+A similar notation 'r1\...r2' is called symmetric difference
+of 'r1' and 'r2' and is defined as
+'r1 r2 --not $(git merge-base --all r1 r2)'.
+It is the set of commits that are reachable from either one of
+'r1' or 'r2' but not from both.
+
+Two other shorthands for naming a set that is formed by a commit
+and its parent commits exist. The 'r1{caret}@' notation means all
+parents of 'r1'. 'r1{caret}!' includes commit 'r1' but excludes
+all of its parents.
+
+Here are a handful of examples:
+
+ D G H D
+ D F G H I J D F
+ ^G D H D
+ ^D B E I J F B
+ B...C G H D E B C
+ ^D B C E I J F B C

+argv-array API
+==============
+
+The argv-array API allows one to dynamically build and store
+NULL-terminated lists. An argv-array maintains the invariant that the
+`argv` member always points to a non-NULL array, and that the array is
+always NULL-terminated at the element pointed to by `argv[argc]`. This
+makes the result suitable for passing to functions expecting to receive
+argv from main(), or the link:api-run-command.html[run-command API].
+
+The link:api-string-list.html[string-list API] is similar, but cannot be
+used for these purposes; instead of storing a straight string pointer,
+it contains an item structure with a `util` field that is not compatible
+with the traditional argv interface.
+
+Each `argv_array` manages its own memory. Any strings pushed into the
+array are duplicated, and all memory is freed by argv_array_clear().
+
+Data Structures
+---------------
+
+`struct argv_array`::
+
+ A single array. This should be initialized by assignment from
+ `ARGV_ARRAY_INIT`, or by calling `argv_array_init`. The `argv`
+ member contains the actual array; the `argc` member contains the
+ number of elements in the array, not including the terminating
+ NULL.
+
+Functions
+---------
+
+`argv_array_init`::
+ Initialize an array. This is no different than assigning from
+ `ARGV_ARRAY_INIT`.
+
+`argv_array_push`::
+ Push a copy of a string onto the end of the array.
+
+`argv_array_pushf`::
+ Format a string and push it onto the end of the array. This is a
+ convenience wrapper combining `strbuf_addf` and `argv_array_push`.
+
+`argv_array_clear`::
+ Free all memory associated with the array and return it to the
+ initial, empty state.

+merge API
+=========
+
+The merge API helps a program to reconcile two competing sets of
+improvements to some files (e.g., unregistered changes from the work
+tree versus changes involved in switching to a new branch), reporting
+conflicts if found. The library called through this API is
+responsible for a few things.
+
+ * determining which trees to merge (recursive ancestor consolidation);
+
+ * lining up corresponding files in the trees to be merged (rename
+ detection, subtree shifting), reporting edge cases like add/add
+ and rename/rename conflicts to the user;
+
+ * performing a three-way merge of corresponding files, taking
+ path-specific merge drivers (specified in `.gitattributes`)
+ into account.
+
+Data structures
+---------------
+
+* `mmbuffer_t`, `mmfile_t`
+
+These store data usable for use by the xdiff backend, for writing and
+for reading, respectively. See `xdiff/xdiff.h` for the definitions
+and `diff.c` for examples.
+
+* `struct ll_merge_options`
+
+This describes the set of options the calling program wants to affect
+the operation of a low-level (single file) merge. Some options:
+
+`virtual_ancestor`::
+ Behave as though this were part of a merge between common
+ ancestors in a recursive merge.
+ If a helper program is specified by the
+ `[merge "<driver>"] recursive` configuration, it will
+ be used (see linkgit:gitattributes[5]).
+
+`variant`::
+ Resolve local conflicts automatically in favor
+ of one side or the other (as in 'git merge-file'
+ `--ours`/`--theirs`/`--union`). Can be `0`,
+ `XDL_MERGE_FAVOR_OURS`, `XDL_MERGE_FAVOR_THEIRS`, or
+ `XDL_MERGE_FAVOR_UNION`.
+
+`renormalize`::
+ Resmudge and clean the "base", "theirs" and "ours" files
+ before merging. Use this when the merge is likely to have
+ overlapped with a change in smudge/clean or end-of-line
+ normalization rules.
+
+Low-level (single file) merge
+-----------------------------
+
+`ll_merge`::
+
+ Perform a three-way single-file merge in core. This is
+ a thin wrapper around `xdl_merge` that takes the path and
+ any merge backend specified in `.gitattributes` or
+ `.git/info/attributes` into account. Returns 0 for a
+ clean merge.
+
+Calling sequence:
+
+* Prepare a `struct ll_merge_options` to record options.
+ If you have no special requests, skip this and pass `NULL`
+ as the `opts` parameter to use the default options.
+
+* Allocate an mmbuffer_t variable for the result.
+
+* Allocate and fill variables with the file's original content
+ and two modified versions (using `read_mmfile`, for example).
+
+* Call `ll_merge()`.
+
+* Read the merged content from `result_buf.ptr` and `result_buf.size`.
+
+* Release buffers when finished. A simple
+ `free(ancestor.ptr); free(ours.ptr); free(theirs.ptr);
+ free(result_buf.ptr);` will do.
+
+If the modifications do not merge cleanly, `ll_merge` will return a
+nonzero value and `result_buf` will generally include a description of
+the conflict bracketed by markers such as the traditional `<<<<<<<`
+and `>>>>>>>`.
+
+The `ancestor_label`, `our_label`, and `their_label` parameters are
+used to label the different sides of a conflict if the merge driver
+supports this.
+
+Everything else
+---------------
+
+Talk about <merge-recursive.h> and merge_file():
+
+ - merge_trees() to merge with rename detection
+ - merge_recursive() for ancestor consolidation
+ - try_merge_command() for other strategies
+ - conflict format
+ - merge options

+ref iteration API
+=================
+
+
+Iteration of refs is done by using an iterate function which will call a
+callback function for every ref. The callback function has this
+signature:
+
+ int handle_one_ref(const char *refname, const unsigned char *sha1,
+ int flags, void *cb_data);
+
+There are different kinds of iterate functions which all take a
+callback of this type. The callback is then called for each found ref
+until the callback returns nonzero. The returned value is then also
+returned by the iterate function.
+
+Iteration functions
+-------------------
+
+* `head_ref()` just iterates the head ref.
+
+* `for_each_ref()` iterates all refs.
+
+* `for_each_ref_in()` iterates all refs which have a defined prefix and
+ strips that prefix from the passed variable refname.
+
+* `for_each_tag_ref()`, `for_each_branch_ref()`, `for_each_remote_ref()`,
+ `for_each_replace_ref()` iterate refs from the respective area.
+
+* `for_each_glob_ref()` iterates all refs that match the specified glob
+ pattern.
+
+* `for_each_glob_ref_in()` the previous and `for_each_ref_in()` combined.
+
+* `head_ref_submodule()`, `for_each_ref_submodule()`,
+ `for_each_ref_in_submodule()`, `for_each_tag_ref_submodule()`,
+ `for_each_branch_ref_submodule()`, `for_each_remote_ref_submodule()`
+ do the same as the functions descibed above but for a specified
+ submodule.
+
+* `for_each_rawref()` can be used to learn about broken ref and symref.
+
+* `for_each_reflog()` iterates each reflog file.
+
+Submodules
+----------
+
+If you want to iterate the refs of a submodule you first need to add the
+submodules object database. You can do this by a code-snippet like
+this:
+
+ const char *path = "path/to/submodule"
+ if (!add_submodule_odb(path))
+ die("Error submodule '%s' not populated.", path);
+
+`add_submodule_odb()` will return an non-zero value on success. If you
+do not do this you will get an error for each ref that it does not point
+to a valid object.
+
+Note: As a side-effect of this you can not safely assume that all
+objects you lookup are available in superproject. All submodule objects
+will be available the same way as the superprojects objects.
+
+Example:
+--------
+
+----
+static int handle_remote_ref(const char *refname,
+ const unsigned char *sha1, int flags, void *cb_data)
+{
+ struct strbuf *output = cb_data;
+ strbuf_addf(output, "%s\n", refname);
+ return 0;
+}
+
+...
+
+ struct strbuf output = STRBUF_INIT;
+ for_each_remote_ref(handle_remote_ref, &output);
+ printf("%s", output.buf);

+sha1-array API
+==============
+
+The sha1-array API provides storage and manipulation of sets of SHA1
+identifiers. The emphasis is on storage and processing efficiency,
+making them suitable for large lists. Note that the ordering of items is
+not preserved over some operations.
+
+Data Structures
+---------------
+
+`struct sha1_array`::
+
+ A single array of SHA1 hashes. This should be initialized by
+ assignment from `SHA1_ARRAY_INIT`. The `sha1` member contains
+ the actual data. The `nr` member contains the number of items in
+ the set. The `alloc` and `sorted` members are used internally,
+ and should not be needed by API callers.
+
+Functions
+---------
+
+`sha1_array_append`::
+ Add an item to the set. The sha1 will be placed at the end of
+ the array (but note that some operations below may lose this
+ ordering).
+
+`sha1_array_sort`::
+ Sort the elements in the array.
+
+`sha1_array_lookup`::
+ Perform a binary search of the array for a specific sha1.
+ If found, returns the offset (in number of elements) of the
+ sha1. If not found, returns a negative integer. If the array is
+ not sorted, this function has the side effect of sorting it.
+
+`sha1_array_clear`::
+ Free all memory associated with the array and return it to the
+ initial, empty state.
+
+`sha1_array_for_each_unique`::
+ Efficiently iterate over each unique element of the list,
+ executing the callback function for each one. If the array is
+ not sorted, this function has the side effect of sorting it.
+
+Examples
+--------
+
+-----------------------------------------
+void print_callback(const unsigned char sha1[20],
+ void *data)
+{
+ printf("%s\n", sha1_to_hex(sha1));

+ * Print the unique set of objects. We could also have

+GIT index format
+================
+
+= The git index file has the following format
+
+ All binary numbers are in network byte order. Version 2 is described
+ here unless stated otherwise.
+
+ - A 12-byte header consisting of
+
+ 4-byte signature:
+ The signature is { 'D', 'I', 'R', 'C' } (stands for "dircache")
+
+ 4-byte version number:
+ The current supported versions are 2 and 3.
+
+ 32-bit number of index entries.
+
+ - A number of sorted index entries (see below).
+
+ - Extensions
+
+ Extensions are identified by signature. Optional extensions can
+ be ignored if GIT does not understand them.
+
+ GIT currently supports cached tree and resolve undo extensions.
+
+ 4-byte extension signature. If the first byte is 'A'..'Z' the
+ extension is optional and can be ignored.
+
+ 32-bit size of the extension
+
+ Extension data
+
+ - 160-bit SHA-1 over the content of the index file before this
+ checksum.
+
+== Index entry
+
+ Index entries are sorted in ascending order on the name field,
+ interpreted as a string of unsigned bytes (i.e. memcmp() order, no
+ localization, no special casing of directory separator '/'). Entries
+ with the same name are sorted by their stage field.
+
+ 32-bit ctime seconds, the last time a file's metadata changed
+ this is stat(2) data
+
+ 32-bit ctime nanosecond fractions
+ this is stat(2) data
+
+ 32-bit mtime seconds, the last time a file's data changed
+ this is stat(2) data
+
+ 32-bit mtime nanosecond fractions
+ this is stat(2) data
+
+ 32-bit dev
+ this is stat(2) data
+
+ 32-bit ino
+ this is stat(2) data
+
+ 32-bit mode, split into (high to low bits)
+
+ 4-bit object type
+ valid values in binary are 1000 (regular file), 1010 (symbolic link)
+ and 1110 (gitlink)
+
+ 3-bit unused
+
+ 9-bit unix permission. Only 0755 and 0644 are valid for regular files.
+ Symbolic links and gitlinks have value 0 in this field.
+
+ 32-bit uid
+ this is stat(2) data
+
+ 32-bit gid
+ this is stat(2) data
+
+ 32-bit file size
+ This is the on-disk size from stat(2), truncated to 32-bit.
+
+ 160-bit SHA-1 for the represented object
+
+ A 16-bit 'flags' field split into (high to low bits)
+
+ 1-bit assume-valid flag
+
+ 1-bit extended flag (must be zero in version 2)
+
+ 2-bit stage (during merge)
+
+ 12-bit name length if the length is less than 0xFFF; otherwise 0xFFF
+ is stored in this field.
+
+ (Version 3) A 16-bit field, only applicable if the "extended flag"
+ above is 1, split into (high to low bits).
+
+ 1-bit reserved for future
+
+ 1-bit skip-worktree flag (used by sparse checkout)
+
+ 1-bit intent-to-add flag (used by "git add -N")
+
+ 13-bit unused, must be zero
+
+ Entry path name (variable length) relative to top level directory
+ (without leading slash). '/' is used as path separator. The special
+ path components ".", ".." and ".git" (without quotes) are disallowed.
+ Trailing slash is also disallowed.
+
+ The exact encoding is undefined, but the '.' and '/' characters
+ are encoded in 7-bit ASCII and the encoding cannot contain a NUL
+ byte (iow, this is a UNIX pathname).
+
+ 1-8 nul bytes as necessary to pad the entry to a multiple of eight bytes
+ while keeping the name NUL-terminated.
+
+== Extensions
+
+=== Cached tree
+
+ Cached tree extension contains pre-computed hashes for trees that can
+ be derived from the index. It helps speed up tree object generation
+ from index for a new commit.
+
+ When a path is updated in index, the path must be invalidated and
+ removed from tree cache.
+
+ The signature for this extension is { 'T', 'R', 'E', 'E' }.
+
+ A series of entries fill the entire extension; each of which
+ consists of:
+
+ - NUL-terminated path component (relative to its parent directory);
+
+ - ASCII decimal number of entries in the index that is covered by the
+ tree this entry represents (entry_count);
+
+ - A space (ASCII 32);
+
+ - ASCII decimal number that represents the number of subtrees this
+ tree has;
+
+ - A newline (ASCII 10); and
+
+ - 160-bit object name for the object that would result from writing
+ this span of index as a tree.
+
+ An entry can be in an invalidated state and is represented by having
+ -1 in the entry_count field. In this case, there is no object name
+ and the next entry starts immediately after the newline.
+
+ The entries are written out in the top-down, depth-first order. The
+ first entry represents the root level of the repository, followed by the
+ first subtree---let's call this A---of the root level (with its name
+ relative to the root level), followed by the first subtree of A (with
+ its name relative to A), ...
+
+=== Resolve undo
+
+ A conflict is represented in the index as a set of higher stage entries.
+ When a conflict is resolved (e.g. with "git add path"), these higher
+ stage entries will be removed and a stage-0 entry with proper resoluton
+ is added.
+
+ When these higher stage entries are removed, they are saved in the
+ resolve undo extension, so that conflicts can be recreated (e.g. with
+ "git checkout -m"), in case users want to redo a conflict resolution
+ from scratch.
+
+ The signature for this extension is { 'R', 'E', 'U', 'C' }.
+
+ A series of entries fill the entire extension; each of which
+ consists of:
+
+ - NUL-terminated pathname the entry describes (relative to the root of
+ the repository, i.e. full pathname);
+
+ - Three NUL-terminated ASCII octal numbers, entry mode of entries in
+ stage 1 to 3 (a missing stage is represented by "0" in this field);
+ and
+
+ - At most three 160-bit object names of the entry in stages from 1 to 3
+ (nothing is written for a missing stage).

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Lesser General Public License for more details.
+
+ You should have received a copy of the GNU Lesser General Public
+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James Random Hacker.

- * Careful: order of argument flags does matter. For example,
- *
- * git checkout-index -a -f file.c
- *
- * Will first check out all files listed in the cache (but not
- * overwrite any old ones), and then force-checkout "file.c" a
- * second time (ie that one _will_ overwrite any old contents
- * with the same filename).
- *
- * Also, just doing "git checkout-index" does nothing. You probably
- * meant "git checkout-index -a". And if you want to force it, you
- * want "git checkout-index -f -a".
- *
- * Intuitiveness is not the goal here. Repeatability is. The
- * reason for the "no arguments means no work" thing is that
- * from scripts you are supposed to be able to do things like
- *
- * find . -name '*.h' -print0 | xargs -0 git checkout-index -f --
- *
- * or:
- *
- * find . -name '*.h' -print0 | git checkout-index -f -z --stdin
- *
- * which will force all existing *.h files to be replaced with
- * their cached copies. If an empty command line implied "all",
- * then this would force-refresh everything in the cache, which
- * was not the point.
- *
- * Oh, and the "--" is just a good idea when you know the rest
- * will be filenames. Just so that you wouldn't have a filename
- * of "-a" causing problems (not possible in the above example,
- * but get used to it in scripting!).

+/* Summary:
+
+All the apparent functions defined here are macros. The idea
+is that you would use these pre-tested macros to solve a
+very specific set of problems, and they would run fast.
+Caution: no side-effects in arguments please!! They may be
+evaluated MANY times!!
+
+These macros operate a stack of objects. Each object starts life
+small, and may grow to maturity. (Consider building a word syllable
+by syllable.) An object can move while it is growing. Once it has
+been "finished" it never changes address again. So the "top of the
+stack" is typically an immature growing object, while the rest of the
+stack is of mature, fixed size and fixed address objects.
+
+These routines grab large chunks of memory, using a function you
+supply, called `obstack_chunk_alloc'. On occasion, they free chunks,
+by calling `obstack_chunk_free'. You must define them and declare
+them before using any obstack macros.
+
+Each independent stack is represented by a `struct obstack'.
+Each of the obstack macros expects a pointer to such a structure
+as the first argument.
+
+One motivation for this package is the problem of growing char strings
+in symbol tables. Unless you are "fascist pig with a read-only mind"
+--Gosper's immortal quote from HAKMEM item 154, out of context--you
+would not like to put any arbitrary upper limit on the length of your
+symbols.
+
+In practice this often means you will build many short symbols and a
+few long symbols. At the time you are reading a symbol you don't know
+how long it is. One traditional method is to read a symbol into a
+buffer, realloc()ating the buffer every time you try to read a symbol
+that is longer than the buffer. This is beaut, but you still will
+want to copy the symbol from the buffer to a more permanent
+symbol-table entry say about half the time.
+
+With obstacks, you can work differently. Use one obstack for all symbol
+names. As you read a symbol, grow the name in the obstack gradually.
+When the name is complete, finalize it. Then, if the symbol exists already,
+free the newly read name.
+
+The way we do this is to take a large chunk, allocating memory from
+low addresses. When you want to build a symbol in the chunk you just
+add chars above the current "high water mark" in the chunk. When you
+have finished adding chars, because you got to the end of the symbol,
+you know how long the chars are, and you can create a new object.
+Mostly the chars will not burst over the highest address of the chunk,
+because you would typically expect a chunk to be (say) 100 times as
+long as an average object.
+
+In case that isn't clear, when we have enough chars to make up
+the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
+so we just point to it where it lies. No moving of chars is
+needed and this is the second win: potentially long strings need
+never be explicitly shuffled. Once an object is formed, it does not
+change its address during its lifetime.
+
+When the chars burst over a chunk boundary, we allocate a larger
+chunk, and then copy the partly formed object from the end of the old
+chunk to the beginning of the new larger chunk. We then carry on
+accreting characters to the end of the object as we normally would.
+
+A special macro is provided to add a single char at a time to a
+growing object. This allows the use of register variables, which
+break the ordinary 'growth' macro.
+
+Summary:
+ We allocate large chunks.
+ We carve out one object at a time from the current chunk.
+ Once carved, an object never moves.
+ We are free to append data of any size to the currently
+ growing object.
+ Exactly one object is growing in an obstack at any one time.
+ You can run one obstack per control block.
+ You may have as many control blocks as you dare.
+ Because of the way we do it, you can `unwind' an obstack
+ back to a previous state. (You may remove objects much
+ as you would with a stack.)

+diff-highlight
+==============
+
+Line oriented diffs are great for reviewing code, because for most
+hunks, you want to see the old and the new segments of code next to each
+other. Sometimes, though, when an old line and a new line are very
+similar, it's hard to immediately see the difference.
+
+You can use "--color-words" to highlight only the changed portions of
+lines. However, this can often be hard to read for code, as it loses
+the line structure, and you end up with oddly formatted bits.
+
+Instead, this script post-processes the line-oriented diff, finds pairs
+of lines, and highlights the differing segments. It's currently very
+simple and stupid about doing these tasks. In particular:
+
+ 1. It will only highlight a pair of lines if they are the only two
+ lines in a hunk. It could instead try to match up "before" and
+ "after" lines for a given hunk into pairs of similar lines.
+ However, this may end up visually distracting, as the paired
+ lines would have other highlighted lines in between them. And in
+ practice, the lines which most need attention called to their
+ small, hard-to-see changes are touching only a single line.
+
+ 2. It will find the common prefix and suffix of two lines, and
+ consider everything in the middle to be "different". It could
+ instead do a real diff of the characters between the two lines and
+ find common subsequences. However, the point of the highlight is to
+ call attention to a certain area. Even if some small subset of the
+ highlighted area actually didn't change, that's OK. In practice it
+ ends up being more readable to just have a single blob on the line
+ showing the interesting bit.
+
+The goal of the script is therefore not to be exact about highlighting
+changes, but to call attention to areas of interest without being
+visually distracting. Non-diff lines and existing diff coloration is
+preserved; the intent is that the output should look exactly the same as
+the input, except for the occasional highlight.
+
+Use
+---
+
+You can try out the diff-highlight program with:
+
+---------------------------------------------
+git log -p --color | /path/to/diff-highlight
+---------------------------------------------
+
+If you want to use it all the time, drop it in your $PATH and put the
+following in your git configuration:
+
+---------------------------------------------
+[pager]
+ log = diff-highlight | less
+ show = diff-highlight | less
+ diff = diff-highlight | less

+git-jump
+========
+
+Git-jump is a script for helping you jump to "interesting" parts of your
+project in your editor. It works by outputting a set of interesting
+spots in the "quickfix" format, which editors like vim can use as a
+queue of places to visit (this feature is usually used to jump to errors
+produced by a compiler). For example, given a diff like this:
+
+------------------------------------
+diff --git a/foo.c b/foo.c
+index a655540..5a59044 100644
+--- a/foo.c
++++ b/foo.c
+@@ -1,3 +1,3 @@
+ int main(void) {
+- printf("hello word!\n");
++ printf("hello world!\n");
+ }
+-----------------------------------
+
+git-jump will feed this to the editor:
+
+-----------------------------------
+foo.c:2: printf("hello word!\n");
+-----------------------------------
+
+Obviously this trivial case isn't that interesting; you could just open
+`foo.c` yourself. But when you have many changes scattered across a
+project, you can use the editor's support to "jump" from point to point.
+
+Git-jump can generate three types of interesting lists:
+
+ 1. The beginning of any diff hunks.
+
+ 2. The beginning of any merge conflict markers.
+
+ 3. Any grep matches.
+
+
+Using git-jump
+--------------
+
+To use it, just drop git-jump in your PATH, and then invoke it like
+this:
+
+--------------------------------------------------
+# jump to changes not yet staged for commit
+git jump diff
+
+# jump to changes that are staged for commit; you can give
+# arbitrary diff options
+git jump diff --cached
+
+# jump to merge conflicts
+git jump merge
+
+# jump to all instances of foo_bar
+git jump grep foo_bar
+
+# same as above, but case-insensitive; you can give
+# arbitrary grep options
+git jump grep -i foo_bar
+--------------------------------------------------
+
+
+Related Programs
+----------------
+
+You can accomplish some of the same things with individual tools. For
+example, you can use `git mergetool` to start vimdiff on each unmerged
+file. `git jump merge` is for the vim-wielding luddite who just wants to
+jump straight to the conflict text with no fanfare.
+
+As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option,
+which does something similar to `git jump grep`. However, it is limited
+to positioning the cursor to the correct line in only the first file,
+leaving you to locate subsequent hits in that file or other files using
+the editor or pager. By contrast, git-jump provides the editor with a
+complete list of files and line numbers for each match.
+
+
+Limitations
+-----------
+
+This scripts was written and tested with vim. Given that the quickfix
+format is the same as what gcc produces, I expect emacs users have a
+similar feature for iterating through the list, but I know nothing about
+how to activate it.
+
+The shell snippets to generate the quickfix lines will almost certainly
+choke on filenames with exotic characters (like newlines).

+=========
+
+NAME
+----
+svn-fe - convert an SVN "dumpfile" to a fast-import stream
+
+SYNOPSIS
+--------
+[verse]
+svnadmin dump --incremental REPO | svn-fe [url] | git fast-import
+
+DESCRIPTION
+-----------
+
+Converts a Subversion dumpfile into input suitable for
+git-fast-import(1) and similar importers. REPO is a path to a
+Subversion repository mirrored on the local disk. Remote Subversion
+repositories can be mirrored on local disk using the `svnsync`
+command.
+
+Note: this tool is very young. The details of its commandline
+interface may change in backward incompatible ways.
+
+INPUT FORMAT
+------------
+Subversion's repository dump format is documented in full in
+`notes/dump-load-format.txt` from the Subversion source tree.
+Files in this format can be generated using the 'svnadmin dump' or
+'svk admin dump' command.
+
+Dumps produced with 'svnadmin dump --deltas' (dumpfile format v3)
+are not supported.
+
+OUTPUT FORMAT
+-------------
+The fast-import format is documented by the git-fast-import(1)
+manual page.
+
+NOTES
+-----
+Subversion dumps do not record a separate author and committer for
+each revision, nor a separate display name and email address for
+each author. Like git-svn(1), 'svn-fe' will use the name
+
+---------
+user <user@UUID>
+---------
+
+as committer, where 'user' is the value of the `svn:author` property
+and 'UUID' the repository's identifier.
+
+To support incremental imports, 'svn-fe' puts a `git-svn-id` line at
+the end of each commit log message if passed an url on the command
+line. This line has the form `git-svn-id: URL@REVNO UUID`.
+
+The resulting repository will generally require further processing
+to put each project in its own repository and to separate the history
+of each branch. The 'git filter-branch --subdirectory-filter' command
+may be useful for this purpose.
+
+BUGS
+----
+Empty directories and unknown properties are silently discarded.
+
+The exit status does not reflect whether an error was detected.
+

+ *
+ * 2. break both minus-lines and plus-lines into words and
+ * place them into two mmfile_t with one word for each line;
+ *
+ * 3. use xdiff to run diff on the two mmfile_t to get the words level diff;
+ *
+ * And for the common parts of the both file, we output the plus side text.
+ * diff_words->current_plus is used to trace the current position of the plus file
+ * which printed. diff_words->last_minus is used to trace the last minus word
+ * printed.
+ *
+ * For '--graph' to work with '--color-words', we need to output the graph prefix
+ * on each line of color words output. Generally, there are two conditions on
+ * which we should output the prefix.
+ *
+ * 1. diff_words->last_minus == 0 &&
+ * diff_words->current_plus == diff_words->plus.text.ptr
+ *
+ * that is: the plus text must start as a new line, and if there is no minus
+ * word printed, a graph prefix must be printed.
+ *
+ * 2. diff_words->current_plus > diff_words->plus.text.ptr &&
+ * *(diff_words->current_plus - 1) == '\n'

- * get_relative_cwd() gets the prefix of the current working directory
- * relative to 'dir'. If we are not inside 'dir', it returns NULL.
- *
- * As a convenience, it also returns NULL if 'dir' is already NULL. The
- * reason for this behaviour is that it is natural for functions returning
- * directory names to return NULL to say "this directory does not exist"
- * or "this directory is invalid". These cases are usually handled the
- * same as if the cwd is not inside 'dir' at all, so get_relative_cwd()
- * returns NULL for both of them.
- *
- * Most notably, get_relative_cwd(buffer, size, get_git_work_tree())
- * unifies the handling of "outside work tree" with "no work tree at all".
+ * Given two normalized paths (a trailing slash is ok), if subdir is
+ * outside dir, return -1. Otherwise return the offset in subdir that
+ * can be used as relative path to dir.

+
+
+How to configure gitweb for your local system
+---------------------------------------------
+
+You can specify the following configuration variables when building GIT:
+
+ * GIT_BINDIR
+ Points where to find the git executable. You should set it up to
+ the place where the git binary was installed (usually /usr/bin) if you
+ don't install git from sources together with gitweb. [Default: $(bindir)]
+ * GITWEB_SITENAME
+ Shown in the title of all generated pages, defaults to the server name
+ (SERVER_NAME CGI environment variable) if not set. [No default]
+ * GITWEB_PROJECTROOT
+ The root directory for all projects shown by gitweb. Must be set
+ correctly for gitweb to find repositories to display. See also
+ "Gitweb repositories" in the INSTALL file for gitweb. [Default: /pub/git]
+ * GITWEB_PROJECT_MAXDEPTH
+ The filesystem traversing limit for getting the project list; the number
+ is taken as depth relative to the projectroot. It is used when
+ GITWEB_LIST is a directory (or is not set; then project root is used).
+ This is meant to speed up project listing on large work trees by limiting
+ search depth. [Default: 2007]
+ * GITWEB_LIST
+ Points to a directory to scan for projects (defaults to project root
+ if not set / if empty) or to a file with explicit listing of projects
+ (together with projects' ownership). See "Generating projects list
+ using gitweb" in INSTALL file for gitweb to find out how to generate
+ such file from scan of a directory. [No default, which means use root
+ directory for projects]
+ * GITWEB_EXPORT_OK
+ Show repository only if this file exists (in repository). Only
+ effective if this variable evaluates to true. [No default / Not set]
+ * GITWEB_STRICT_EXPORT
+ Only allow viewing of repositories also shown on the overview page.
+ This for example makes GITWEB_EXPORT_OK to decide if repository is
+ available and not only if it is shown. If GITWEB_LIST points to
+ file with list of project, only those repositories listed would be
+ available for gitweb. [No default]
+ * GITWEB_HOMETEXT
+ Points to an .html file which is included on the gitweb project
+ overview page ('projects_list' view), if it exists. Relative to
+ gitweb.cgi script. [Default: indextext.html]
+ * GITWEB_SITE_HTML_HEAD_STRING
+ html snippet to include in the <head> section of each page. [No default]
+ * GITWEB_SITE_HEADER

+ * CSSMIN, JSMIN
+ Invocation of a CSS minifier or a JavaScript minifier, respectively,
+ working as a filter (source on standard input, minified result on

+ corner of each gitweb page, and used as logo for Atom feed). Relative
+ to base URI of gitweb. [Default: static/git-logo.png]
+ * GITWEB_FAVICON
+ Points to the location where you put git-favicon.png on your web server
+ (or to be more generic URI of favicon, assumed to be image/png type;
+ web browsers that support favicons (website icons) may display them
+ in the browser's URL bar and next to site name in bookmarks). Relative

+ * HIGHLIGHT_BIN
+ Path to the highlight executable to use (must be the one from
+ http://www.andre-simon.de due to assumptions about parameters and output).

Gitweb repositories
-------------------
-- By default all git repositories under projectroot are visible and
- available to gitweb. The list of projects is generated by default by
- scanning the projectroot directory for git repositories (for object
- databases to be more exact).
+By default gitweb shows all git repositories under single common repository
+root on a local filesystem; see description of GITWEB_PROJECTROOT build-time
+configuration variable above (and also of GITWEB_LIST).
- You can provide a pre-generated list of [visible] repositories,
- together with information about their owners (the project ownership
- defaults to the owner of the repository directory otherwise), by setting
- the GITWEB_LIST build configuration variable (or the $projects_list
- variable in the gitweb config file) to point to a plain file.
-
- Each line of the projects list file should consist of the url-encoded path
- to the project repository database (relative to projectroot), followed
- by the url-encoded project owner on the same line (separated by a space).
- Spaces in both project path and project owner have to be encoded as either
- '%20' or '+'.
-
- Other characters that have to be url-encoded, i.e. replaced by '%'
- followed by two-digit character number in octal, are: other whitespace
- characters (because they are field separator in a record), plus sign '+'
- (because it can be used as replacement for spaces), and percent sign '%'
- (which is used for encoding / escaping).
-
- You can generate the projects list index file using the project_index
- action (the 'TXT' link on projects list page) directly from gitweb.
-
-- By default, even if a project is not visible on projects list page, you
- can view it nevertheless by hand-crafting a gitweb URL. You can set the
- GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export
- variable in the gitweb config file) to only allow viewing of
- repositories also shown on the overview page.
-
-- Alternatively, you can configure gitweb to only list and allow
- viewing of the explicitly exported repositories, via the
- GITWEB_EXPORT_OK build configuration variable (or the $export_ok
- variable in gitweb config file). If it evaluates to true, gitweb
- shows repositories only if this file exists in its object database
- (if directory has the magic file named $export_ok).
-
-- Finally, it is possible to specify an arbitrary perl subroutine that
- will be called for each project to determine if it can be exported.
- The subroutine receives an absolute path to the project as its only
- parameter.
-
- For example, if you use mod_perl to run the script, and have dumb
- http protocol authentication configured for your repositories, you
- can use the following hook to allow access only if the user is
- authorized to read the files:
-
- $export_auth_hook = sub {
- use Apache2::SubRequest ();
- use Apache2::Const -compile => qw(HTTP_OK);
- my $path = "$_[0]/HEAD";
- my $r = Apache2::RequestUtil->request;
- my $sub = $r->lookup_file($path);
- return $sub->filename eq $path
- && $sub->status == Apache2::Const::HTTP_OK;
- };

-Generating projects list using gitweb
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-We assume that GITWEB_CONFIG has its default Makefile value, namely
-gitweb_config.perl. Put the following in gitweb_make_index.perl file:
-
- $GITWEB_CONFIG = "gitweb_config.perl";
- do $GITWEB_CONFIG if -e $GITWEB_CONFIG;
-
- $projects_list = $projectroot;
-
-Then create the following script to get list of project in the format
-suitable for GITWEB_LIST build configuration variable (or
-$projects_list variable in gitweb config):
-
- #!/bin/sh
-
- export GITWEB_CONFIG="gitweb_make_index.perl"
- export GATEWAY_INTERFACE="CGI/1.1"
- export HTTP_ACCEPT="*/*"
- export REQUEST_METHOD="GET"
- export QUERY_STRING="a=project_index"
-
- perl -- /var/www/cgi-bin/gitweb.cgi
-
-

From the git version 1.4.0 gitweb is bundled with git.
-How to configure gitweb for your local system
----------------------------------------------
+Build time gitweb configuration
+-------------------------------
+There are many configuration variables which affect building gitweb (among
+others creating gitweb.cgi out of gitweb.perl by replacing placeholders such
+as `++GIT_BINDIR++` by their build-time values).
-See also the "Build time configuration" section in the INSTALL
-file for gitweb (in gitweb/INSTALL).
-
-You can specify the following configuration variables when building GIT:
- * GIT_BINDIR
- Points where to find the git executable. You should set it up to
- the place where the git binary was installed (usually /usr/bin) if you
- don't install git from sources together with gitweb. [Default: $(bindir)]
- * GITWEB_SITENAME
- Shown in the title of all generated pages, defaults to the server name
- (SERVER_NAME CGI environment variable) if not set. [No default]
- * GITWEB_PROJECTROOT
- The root directory for all projects shown by gitweb. Must be set
- correctly for gitweb to find repositories to display. See also
- "Gitweb repositories" in the INSTALL file for gitweb. [Default: /pub/git]
- * GITWEB_PROJECT_MAXDEPTH
- The filesystem traversing limit for getting the project list; the number
- is taken as depth relative to the projectroot. It is used when
- GITWEB_LIST is a directory (or is not set; then project root is used).
- Is is meant to speed up project listing on large work trees by limiting
- search depth. [Default: 2007]
- * GITWEB_LIST
- Points to a directory to scan for projects (defaults to project root
- if not set / if empty) or to a file with explicit listing of projects
- (together with projects' ownership). See "Generating projects list
- using gitweb" in INSTALL file for gitweb to find out how to generate
- such file from scan of a directory. [No default, which means use root
- directory for projects]
- * GITWEB_EXPORT_OK
- Show repository only if this file exists (in repository). Only
- effective if this variable evaluates to true. [No default / Not set]
- * GITWEB_STRICT_EXPORT
- Only allow viewing of repositories also shown on the overview page.
- This for example makes GITWEB_EXPORT_OK to decide if repository is
- available and not only if it is shown. If GITWEB_LIST points to
- file with list of project, only those repositories listed would be
- available for gitweb. [No default]
- * GITWEB_HOMETEXT
- Points to an .html file which is included on the gitweb project
- overview page ('projects_list' view), if it exists. Relative to
- gitweb.cgi script. [Default: indextext.html]
- * GITWEB_SITE_HEADER
- Filename of html text to include at top of each page. Relative to
- gitweb.cgi script. [No default]
- * GITWEB_SITE_FOOTER
- Filename of html text to include at bottom of each page. Relative to
- gitweb.cgi script. [No default]
- * GITWEB_HOME_LINK_STR
- String of the home link on top of all pages, leading to $home_link
- (usually main gitweb page, which means projects list). Used as first
- part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
- [Default: projects]
- * GITWEB_SITENAME
- Name of your site or organization to appear in page titles. Set it
- to something descriptive for clearer bookmarks etc. If not set
- (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
- SERVER_NAME CGI environment variable is not set (e.g. if running
- gitweb as standalone script). [No default]
- * GITWEB_BASE_URL
- Git base URLs used for URL to where fetch project from, i.e. full
- URL is "$git_base_url/$project". Shown on projects summary page.
- Repository URL for project can be also configured per repository; this
- takes precedence over URLs composed from base URL and a project name.
- Note that you can setup multiple base URLs (for example one for
- git:// protocol access, another for http:// access) from the gitweb
- config file. [No default]
- * GITWEB_CSS
- Points to the location where you put gitweb.css on your web server
- (or to be more generic, the URI of gitweb stylesheet). Relative to the
- base URI of gitweb. Note that you can setup multiple stylesheets from
- the gitweb config file. [Default: gitweb.css]
- * GITWEB_LOGO
- Points to the location where you put git-logo.png on your web server
- (or to be more generic URI of logo, 72x27 size, displayed in top right
- corner of each gitweb page, and used as logo for Atom feed). Relative
- to base URI of gitweb. [Default: git-logo.png]
- * GITWEB_FAVICON
- Points to the location where you put git-favicon.png on your web server
- (or to be more generic URI of favicon, assumed to be image/png type;
- web browsers that support favicons (website icons) may display them
- in the browser's URL bar and next to site name in bookmarks). Relative
- to base URI of gitweb. [Default: git-favicon.png]
- * GITWEB_JS
- Points to the localtion where you put gitweb.js on your web server
- (or to be more generic URI of JavaScript code used by gitweb).
- Relative to base URI of gitweb. [Default: gitweb.js (or gitweb.min.js
- if JSMIN build variable is defined / JavaScript minifier is used)]
- * GITWEB_CONFIG
- This Perl file will be loaded using 'do' and can be used to override any
- of the options above as well as some other options -- see the "Runtime
- gitweb configuration" section below, and top of 'gitweb.cgi' for their
- full list and description. If the environment variable GITWEB_CONFIG
- is set when gitweb.cgi is executed, then the file specified in the
- environment variable will be loaded instead of the file specified
- when gitweb.cgi was created. [Default: gitweb_config.perl]
- * GITWEB_CONFIG_SYSTEM
- This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG
- does not exist. If the environment variable GITWEB_CONFIG_SYSTEM is set
- when gitweb.cgi is executed, then the file specified in the environment
- variable will be loaded instead of the file specified when gitweb.cgi was
- created. [Default: /etc/gitweb.conf]
+Building and installing gitweb is described in gitweb's INSTALL file
+(in 'gitweb/INSTALL').
Runtime gitweb configuration
----------------------------
+Gitweb obtains configuration data from the following sources in the
+following order:
-You can adjust gitweb behaviour using the file specified in `GITWEB_CONFIG`
-(defaults to 'gitweb_config.perl' in the same directory as the CGI), and
-as a fallback `GITWEB_CONFIG_SYSTEM` (defaults to /etc/gitweb.conf).
+1. built-in values (some set during build stage),
+2. common system-wide configuration file (`GITWEB_CONFIG_COMMON`,
+ defaults to '/etc/gitweb-common.conf'),
+3. either per-instance configuration file (`GITWEB_CONFIG`, defaults to
+ 'gitweb_config.perl' in the same directory as the installed gitweb),
+ or if it does not exists then system-wide configuration file
+ (`GITWEB_CONFIG_SYSTEM`, defaults to '/etc/gitweb.conf').
+
+Values obtained in later configuration files override values obtained earlier
+in above sequence.
+
+You can read defaults in system-wide GITWEB_CONFIG_SYSTEM from GITWEB_CONFIG
+by adding
+
+ read_config_file($GITWEB_CONFIG_SYSTEM);
+
+at very beginning of per-instance GITWEB_CONFIG file. In this case
+settings in said per-instance file will override settings from
+system-wide configuration file. Note that read_config_file checks
+itself that the $GITWEB_CONFIG_SYSTEM file exists.

+Web server configuration
+------------------------
+Gitweb can be run as CGI script, as legacy mod_perl application (using
+ModPerl::Registry), and as FastCGI script. You can find some simple examples
+in "Example web server configuration" section in INSTALL file for gitweb (in
+gitweb/INSTALL).
-Below is the list of variables which you might want to set in gitweb config.
-See the top of 'gitweb.cgi' for the full list of variables and their
-descriptions.
-
-Gitweb config file variables
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can set, among others, the following variables in gitweb config files
-(with the exception of $projectroot and $projects_list this list does
-not include variables usually directly set during build):
- * $GIT
- Core git executable to use. By default set to "$GIT_BINDIR/git", which
- in turn is by default set to "$(bindir)/git". If you use git from binary
- package, set this to "/usr/bin/git". This can just be "git" if your
- webserver has a sensible PATH. If you have multiple git versions
- installed it can be used to choose which one to use.
- * $version
- Gitweb version, set automatically when creating gitweb.cgi from
- gitweb.perl. You might want to modify it if you are running modified
- gitweb.
- * $projectroot
- Absolute filesystem path which will be prepended to project path;
- the path to repository is $projectroot/$project. Set to
- $GITWEB_PROJECTROOT during installation. This variable have to be
- set correctly for gitweb to find repositories.
- * $projects_list
- Source of projects list, either directory to scan, or text file
- with list of repositories (in the "<URI-encoded repository path> SP
- <URI-encoded repository owner>" line format; actually there can be
- any sequence of whitespace in place of space (SP)). Set to
- $GITWEB_LIST during installation. If empty, $projectroot is used
- to scan for repositories.
- * $my_url, $my_uri
- Full URL and absolute URL of gitweb script;
- in earlier versions of gitweb you might have need to set those
- variables, now there should be no need to do it.
- * $base_url
- Base URL for relative URLs in pages generated by gitweb,
- (e.g. $logo, $favicon, @stylesheets if they are relative URLs),
- needed and used only for URLs with nonempty PATH_INFO via
- <base href="$base_url>. Usually gitweb sets its value correctly,
- and there is no need to set this variable, e.g. to $my_uri or "/".
- * $home_link
- Target of the home link on top of all pages (the first part of view
- "breadcrumbs"). By default set to absolute URI of a page ($my_uri).
- * @stylesheets
- List of URIs of stylesheets (relative to base URI of a page). You
- might specify more than one stylesheet, for example use gitweb.css
- as base, with site specific modifications in separate stylesheet
- to make it easier to upgrade gitweb. You can add 'site' stylesheet
- for example by using
- push @stylesheets, "gitweb-site.css";
- in the gitweb config file.
- * $logo_url, $logo_label
- URI and label (title) of GIT logo link (or your site logo, if you choose
- to use different logo image). By default they point to git homepage;
- in the past they pointed to git documentation at www.kernel.org.
- * $projects_list_description_width
- The width (in characters) of the projects list "Description" column.
- Longer descriptions will be cut (trying to cut at word boundary);
- full description is available as 'title' attribute (usually shown on
- mouseover). By default set to 25, which might be too small if you
- use long project descriptions.
- * @git_base_url_list
- List of git base URLs used for URL to where fetch project from, shown
- in project summary page. Full URL is "$git_base_url/$project".
- You can setup multiple base URLs (for example one for git:// protocol
- access, and one for http:// "dumb" protocol access). Note that per
- repository configuration in 'cloneurl' file, or as values of gitweb.url
- project config.
- * $default_blob_plain_mimetype
- Default mimetype for blob_plain (raw) view, if mimetype checking
- doesn't result in some other type; by default 'text/plain'.
- * $default_text_plain_charset
- Default charset for text files. If not set, web server configuration
- would be used.
- * $mimetypes_file
- File to use for (filename extension based) guessing of MIME types before
- trying /etc/mime.types. Path, if relative, is taken currently as
- relative to the current git repository.
- * $fallback_encoding
- Gitweb assumes this charset if line contains non-UTF-8 characters.
- Fallback decoding is used without error checking, so it can be even
- 'utf-8'. Value must be valid encoding; see Encoding::Supported(3pm) man
- page for a list. By default 'latin1', aka. 'iso-8859-1'.
- * @diff_opts
- Rename detection options for git-diff and git-diff-tree. By default
- ('-M'); set it to ('-C') or ('-C', '-C') to also detect copies, or
- set it to () if you don't want to have renames detection.
- * $prevent_xss
- If true, some gitweb features are disabled to prevent content in
- repositories from launching cross-site scripting (XSS) attacks. Set this
- to true if you don't trust the content of your repositories. The default
- is false.
+See "Webserver configuration" and "Advanced web server setup" sections in
+gitweb(1) manpage.
-Projects list file format
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Instead of having gitweb find repositories by scanning filesystem starting
-from $projectroot (or $projects_list, if it points to directory), you can
-provide list of projects by setting $projects_list to a text file with list
-of projects (and some additional info). This file uses the following
-format:
-
-One record (for project / repository) per line, whitespace separated fields;
-does not support (at least for now) lines continuation (newline escaping).
-Leading and trailing whitespace are ignored, any run of whitespace can be
-used as field separator (rules for Perl's "split(' ', $line)"). Keyed by
-the first field, which is project name, i.e. path to repository GIT_DIR
-relative to $projectroot. Fields use modified URI encoding, defined in
-RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding"
-(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference
-being that SP (' ') can be encoded as '+' (and therefore '+' has to be also
-percent-encoded). Reserved characters are: '%' (used for encoding), '+'
-(can be used to encode SPACE), all whitespace characters as defined in Perl,
-including SP, TAB and LF, (used to separate fields in a record).
-
-Currently list of fields is
- * <repository path> - path to repository GIT_DIR, relative to $projectroot
- * <repository owner> - displayed as repository owner, preferably full name,
- or email, or both
-
-You can additionally use $projects_list file to limit which repositories
-are visible, and together with $strict_export to limit access to
-repositories (see "Gitweb repositories" section in gitweb/INSTALL).
-
-
-Per-repository gitweb configuration
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can also configure individual repositories shown in gitweb by creating
-file in the GIT_DIR of git repository, or by setting some repo configuration
-variable (in GIT_DIR/config).
-
-You can use the following files in repository:
- * README.html
- A .html file (HTML fragment) which is included on the gitweb project
- summary page inside <div> block element. You can use it for longer
- description of a project, to provide links (for example to project's
- homepage), etc. This is recognized only if XSS prevention is off
- ($prevent_xss is false); a way to include a readme safely when XSS
- prevention is on may be worked out in the future.
- * description (or gitweb.description)
- Short (shortened by default to 25 characters in the projects list page)
- single line description of a project (of a repository). Plain text file;
- HTML will be escaped. By default set to
- Unnamed repository; edit this file to name it for gitweb.
- from the template during repository creation. You can use the
- gitweb.description repo configuration variable, but the file takes
- precedence.
- * cloneurl (or multiple-valued gitweb.url)
- File with repository URL (used for clone and fetch), one per line.
- Displayed in the project summary page. You can use multiple-valued
- gitweb.url repository configuration variable for that, but the file
- takes precedence.
- * gitweb.owner
- You can use the gitweb.owner repository configuration variable to set
- repository's owner. It is displayed in the project list and summary
- page. If it's not set, filesystem directory's owner is used
- (via GECOS field / real name field from getpwiud(3)).
- * various gitweb.* config variables (in config)
- Read description of %feature hash for detailed list, and some
- descriptions.
-
-
-Webserver configuration
------------------------
-
-If you want to have one URL for both gitweb and your http://
-repositories, you can configure apache like this:
-
-<VirtualHost *:80>
- ServerName git.example.org
- DocumentRoot /pub/git
- SetEnv GITWEB_CONFIG /etc/gitweb.conf
- RewriteEngine on
- # make the front page an internal rewrite to the gitweb script
- RewriteRule ^/$ /cgi-bin/gitweb.cgi
- # make access for "dumb clients" work
- RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT]
-</VirtualHost>
-
-The above configuration expects your public repositories to live under
-/pub/git and will serve them as http://git.domain.org/dir-under-pub-git,
-both as cloneable GIT URL and as browseable gitweb interface.
-If you then start your git-daemon with --base-path=/pub/git --export-all
-then you can even use the git:// URL with exactly the same path.
-
-Setting the environment variable GITWEB_CONFIG will tell gitweb to use
-the named file (i.e. in this example /etc/gitweb.conf) as a
-configuration for gitweb. Perl variables defined in here will
-override the defaults given at the head of the gitweb.perl (or
-gitweb.cgi). Look at the comments in that file for information on
-which variables and what they mean.
-
-If you use the rewrite rules from the example you'll likely also need
-something like the following in your gitweb.conf (or gitweb_config.perl) file:
-
- @stylesheets = ("/some/absolute/path/gitweb.css");
- $my_uri = "/";
- $home_link = "/";
-
-
-PATH_INFO usage
------------------------
-If you enable PATH_INFO usage in gitweb by putting
-
- $feature{'pathinfo'}{'default'} = [1];
-
-in your gitweb.conf, it is possible to set up your server so that it
-consumes and produces URLs in the form
-
-http://git.example.com/project.git/shortlog/sometag
-
-by using a configuration such as the following, that assumes that
-/var/www/gitweb is the DocumentRoot of your webserver, and that it
-contains the gitweb.cgi script and complementary static files
-(stylesheet, favicon):
-
-<VirtualHost *:80>
- ServerAlias git.example.com
-
- DocumentRoot /var/www/gitweb
-
- <Directory /var/www/gitweb>
- Options ExecCGI
- AddHandler cgi-script cgi
-
- DirectoryIndex gitweb.cgi
-
- RewriteEngine On
- RewriteCond %{REQUEST_FILENAME} !-f
- RewriteCond %{REQUEST_FILENAME} !-d
- RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
- </Directory>
-</VirtualHost>
-
-The rewrite rule guarantees that existing static files will be properly
-served, whereas any other URL will be passed to gitweb as PATH_INFO
-parameter.
-
-Notice that in this case you don't need special settings for
-@stylesheets, $my_uri and $home_link, but you lose "dumb client" access
-to your project .git dirs. A possible workaround for the latter is the
-following: in your project root dir (e.g. /pub/git) have the projects
-named without a .git extension (e.g. /pub/git/project instead of
-/pub/git/project.git) and configure Apache as follows:
-
-<VirtualHost *:80>
- ServerAlias git.example.com
-
- DocumentRoot /var/www/gitweb
-
- AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3
- <Directory /var/www/gitweb>
- Options ExecCGI
- AddHandler cgi-script cgi
-
- DirectoryIndex gitweb.cgi
-
- RewriteEngine On
- RewriteCond %{REQUEST_FILENAME} !-f
- RewriteCond %{REQUEST_FILENAME} !-d
- RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
- </Directory>
-</VirtualHost>
-
-The additional AliasMatch makes it so that
-
-http://git.example.com/project.git
-
-will give raw access to the project's git dir (so that the project can
-be cloned), while
-
-http://git.example.com/project
-
-will provide human-friendly gitweb access.
-
-This solution is not 100% bulletproof, in the sense that if some project
-has a named ref (branch, tag) starting with 'git/', then paths such as
-
-http://git.example.com/project/command/abranch..git/abranch
-
-will fail with a 404 error.

+GIT web interface (gitweb) - JavaScript
+=======================================
+
+This directory holds JavaScript code used by gitweb (GIT web interface).
+Scripts from there would be concatenated together in the order specified
+by gitweb/Makefile into gitweb/static/gitweb.js, during building of
+gitweb/gitweb.cgi (during gitweb building). The resulting file (or its
+minification) would then be installed / deployed together with gitweb.
+
+Scripts in 'lib/' subdirectory compose generic JavaScript library,
+providing features required by gitweb but in no way limited to gitweb
+only. In the future those scripts could be replaced by some JavaScript
+library / framework, like e.g. jQuery, YUI, Prototype, MooTools, Dojo,
+ExtJS, Script.aculo.us or SproutCore.
+
+All scripts that manipulate gitweb output should be put outside 'lib/',
+directly in this directory ('gitweb/static/js/'). Those scripts would
+have to be rewritten if gitweb moves to using some JavaScript library.

#ifndef STRBUF_H
#define STRBUF_H
-/*
- * Strbuf's can be use in many ways: as a byte array, or to store arbitrary
- * long, overflow safe strings.
- *
- * Strbufs has some invariants that are very important to keep in mind:
- *
- * 1. the ->buf member is always malloc-ed, hence strbuf's can be used to
- * build complex strings/buffers whose final size isn't easily known.
- *
- * It is NOT legal to copy the ->buf pointer away.
- * `strbuf_detach' is the operation that detaches a buffer from its shell
- * while keeping the shell valid wrt its invariants.
- *
- * 2. the ->buf member is a byte array that has at least ->len + 1 bytes
- * allocated. The extra byte is used to store a '\0', allowing the ->buf
- * member to be a valid C-string. Every strbuf function ensure this
- * invariant is preserved.
- *
- * Note that it is OK to "play" with the buffer directly if you work it
- * that way:
- *
- * strbuf_grow(sb, SOME_SIZE);
- * ... Here, the memory array starting at sb->buf, and of length
- * ... strbuf_avail(sb) is all yours, and you are sure that
- * ... strbuf_avail(sb) is at least SOME_SIZE.
- * strbuf_setlen(sb, sb->len + SOME_OTHER_SIZE);
- *
- * Of course, SOME_OTHER_SIZE must be smaller or equal to strbuf_avail(sb).
- *
- * Doing so is safe, though if it has to be done in many places, adding the
- * missing API to the strbuf module is the way to go.
- *
- * XXX: do _not_ assume that the area that is yours is of size ->alloc - 1
- * even if it's true in the current implementation. Alloc is somehow a
- * "private" member that should not be messed with.

+Do's, don'ts & things to keep in mind
+-------------------------------------
+
+Here are a few examples of things you probably should and shouldn't do
+when writing tests.
+
+Do:
+
+ - Put all code inside test_expect_success and other assertions.
+
+ Even code that isn't a test per se, but merely some setup code
+ should be inside a test assertion.
+
+ - Chain your test assertions
+
+ Write test code like this:
+
+ git merge foo &&
+ git push bar &&
+ test ...
+
+ Instead of:
+
+ git merge hla
+ git push gh
+ test ...
+
+ That way all of the commands in your tests will succeed or fail. If
+ you must ignore the return value of something, consider using a
+ helper function (e.g. use sane_unset instead of unset, in order
+ to avoid unportable return value for unsetting a variable that was
+ already unset), or prepending the command with test_might_fail or
+ test_must_fail.
+
+ - Check the test coverage for your tests. See the "Test coverage"
+ below.
+
+ Don't blindly follow test coverage metrics; if a new function you added
+ doesn't have any coverage, then you're probably doing something wrong,
+ but having 100% coverage doesn't necessarily mean that you tested
+ everything.
+
+ Tests that are likely to smoke out future regressions are better
+ than tests that just inflate the coverage metrics.
+
+ - When a test checks for an absolute path that a git command generated,
+ construct the expected value using $(pwd) rather than $PWD,
+ $TEST_DIRECTORY, or $TRASH_DIRECTORY. It makes a difference on
+ Windows, where the shell (MSYS bash) mangles absolute path names.
+ For details, see the commit message of 4114156ae9.
+
+Don't:
+
+ - exit() within a <script> part.
+
+ The harness will catch this as a programming error of the test.
+ Use test_done instead if you need to stop the tests early (see
+ "Skipping tests" below).
+
+ - Break the TAP output
+
+ The raw output from your test may be interpreted by a TAP harness. TAP
+ harnesses will ignore everything they don't know about, but don't step
+ on their toes in these areas:
+
+ - Don't print lines like "$x..$y" where $x and $y are integers.
+
+ - Don't print lines that begin with "ok" or "not ok".
+
+ TAP harnesses expect a line that begins with either "ok" and "not
+ ok" to signal a test passed or failed (and our harness already
+ produces such lines), so your script shouldn't emit such lines to
+ their output.
+
+ You can glean some further possible issues from the TAP grammar
+ (see http://search.cpan.org/perldoc?TAP::Parser::Grammar#TAP_Grammar)
+ but the best indication is to just run the tests with prove(1),
+ it'll complain if anything is amiss.
+
+Keep in mind:
+
+ - Inside <script> part, the standard output and standard error
+ streams are discarded, and the test harness only reports "ok" or
+ "not ok" to the end user running the tests. Under --verbose, they
+ are shown to help debugging the tests.
+
+
+Skipping tests
+--------------
+
+If you need to skip tests you should do so by using the three-arg form
+of the test_* functions (see the "Test harness library" section
+below), e.g.:
+
+ test_expect_success PERL 'I need Perl' "
+ '$PERL_PATH' -e 'hlagh() if unf_unf()'
+ "
+
+The advantage of skipping tests like this is that platforms that don't
+have the PERL and other optional dependencies get an indication of how
+many tests they're missing.
+
+If the test code is too hairy for that (i.e. does a lot of setup work
+outside test assertions) you can also skip all remaining tests by
+setting skip_all and immediately call test_done:
+
+ if ! test_have_prereq PERL
+ then
+ skip_all='skipping perl interface tests, perl not available'
+ test_done
+ fi
+
+The string you give to skip_all will be used as an explanation for why
+the test was skipped.

+ Test is not run by root user, and an attempt to write to an
+ unwritable file is expected to fail correctly.

+
+Test coverage
+-------------
+
+You can use the coverage tests to find code paths that are not being
+used or properly exercised yet.
+
+To do that, run the coverage target at the top-level (not in the t/
+directory):
+
+ make coverage
+
+That'll compile Git with GCC's coverage arguments, and generate a test
+report with gcov after the tests finish. Running the coverage tests
+can take a while, since running the tests in parallel is incompatible
+with GCC's coverage mode.
+
+After the tests have run you can generate a list of untested
+functions:
+
+ make coverage-untested-functions
+
+You can also generate a detailed per-file HTML report using the
+Devel::Cover module. To install it do:
+
+ # On Debian or Ubuntu:
+ sudo aptitude install libdevel-cover-perl
+
+ # From the CPAN with cpanminus
+ curl -L http://cpanmin.us | perl - --sudo --self-upgrade
+ cpanm --sudo Devel::Cover
+
+Then, at the top-level:
+
+ make cover_db_html
+
+That'll generate a detailed cover report in the "cover_db_html"
+directory, which you can then copy to a webserver, or inspect locally
+in a browser.
+
+Smoke testing
+-------------
+
+The Git test suite has support for smoke testing. Smoke testing is
+when you submit the results of a test run to a central server for
+analysis and aggregation.
+
+Running a smoke tester is an easy and valuable way of contributing to
+Git development, particularly if you have access to an uncommon OS on
+obscure hardware.
+
+After building Git you can generate a smoke report like this in the
+"t" directory:
+
+ make clean smoke
+
+You can also pass arguments via the environment. This should make it
+faster:
+
+ GIT_TEST_OPTS='--root=/dev/shm' TEST_JOBS=10 make clean smoke
+
+The "smoke" target will run the Git test suite with Perl's
+"TAP::Harness" module, and package up the results in a .tar.gz archive
+with "TAP::Harness::Archive". The former is included with Perl v5.10.1
+or later, but you'll need to install the latter from the CPAN. See the
+"Test coverage" section above for how you might do that.
+
+Once the "smoke" target finishes you'll see a message like this:
+
+ TAP Archive created at <path to git>/t/test-results/git-smoke.tar.gz
+
+To upload the smoke report you need to have curl(1) installed, then
+do:
+
+ make smoke_report
+
+To upload the report anonymously. Hopefully that'll return something
+like "Reported #7 added.".
+
+If you're going to be uploading reports frequently please request a
+user account by E-Mailing gitsmoke@v.nix.is. Once you have a username
+and password you'll be able to do:
+
+ SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> make smoke_report
+
+You can also add an additional comment to attach to the report, and/or
+a comma separated list of tags:
+
+ SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> \
+ SMOKE_COMMENT=<comment> SMOKE_TAGS=<tags> \
+ make smoke_report
+
+Once the report is uploaded it'll be made available at
+http://smoke.git.nix.is, here's an overview of Recent Smoke Reports
+for Git:
+
+ http://smoke.git.nix.is/app/projects/smoke_reports/1
+
+The reports will also be mirrored to GitHub every few hours:
+
+ http://github.com/gitsmoke/smoke-reports
+
+The Smolder SQLite database is also mirrored and made available for
+download:
+
+ http://github.com/gitsmoke/smoke-database
+
+Note that the database includes hashed (with crypt()) user passwords
+and E-Mail addresses. Don't use a valuable password for the smoke
+service if you have an account, or an E-Mail address you don't want to
+be publicly known. The user accounts are just meant to be convenient
+labels, they're not meant to be secure.

+test_description='Correctly identify and parse loose object headers
+
+There are two file formats for loose objects - the original standard
+format, and the experimental format introduced with Git v1.4.3, later
+deprecated with v1.5.3. Although Git no longer writes the
+experimental format, objects in both formats must be read, with the
+format for a given file being determined by the header.
+
+Detecting file format based on header is not entirely trivial, not
+least because the first byte of a zlib-deflated stream will vary
+depending on how much memory was allocated for the deflation window
+buffer when the object was written out (for example 4KB on Android,
+rather that 32KB on a normal PC).
+
+The loose objects used as test vectors have been generated with the
+following Git versions:
+
+standard format: Git v1.7.4.1
+experimental format: Git v1.4.3 (legacyheaders=false)
+standard format, deflated with 4KB window size: Agit/JGit on Android

+test_description="Tests of cwd/prefix/worktree/gitdir setup in all cases
+
+A few rules for repo setup:
+
+1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
+ GIT_DIR.
+
+2. .git file is relative to parent directory. .git file is basically
+ symlink in disguise. The directory where .git file points to will
+ become new git_dir.
+
+3. core.worktree is relative to git_dir.
+
+4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
+ equivalent to GIT_WORK_TREE.
+
+5. GIT_WORK_TREE/core.worktree was originally meant to work only if
+ GIT_DIR is set, but earlier git didn't enforce it, and some scripts
+ depend on the implementation that happened to first discover .git by
+ going up from the users $cwd and then using the specified working tree
+ that may or may not have any relation to where .git was found in. This
+ historical behaviour must be kept.
+
+6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
+
+7. Effective core.worktree conflicts with core.bare
+
+8. If GIT_DIR is set but neither worktree nor bare setting is given,
+ original cwd becomes worktree.
+
+9. If .git discovery is done inside a repo, the repo becomes a bare
+ repo. .git discovery is performed if GIT_DIR is not set.
+
+10. If no worktree is available, cwd remains unchanged, prefix is
+ NULL.
+
+11. When user's cwd is outside worktree, cwd remains unchanged,
+ prefix is NULL.

+ Hope, he says, cherishes the soul of him who lives in
+ justice and holiness and is the nurse of his age and the
+ companion of his journey;--hope which is mightiest to sway
+ the restless soul of man.
+
+ How admirable are his words! And the great blessing of riches, I do
+ not say to every man, but to a good man, is, that he has had no
+ occasion to deceive or to defraud others, either intentionally or
+ unintentionally; and when he departs to the world below he is not in
+ any apprehension about offerings due to the gods or debts which he owes
+ to men. Now to this peace of mind the possession of wealth greatly
+ contributes; and therefore I say, that, setting one thing against
+ another, of the many advantages which wealth has to give, to a man of
+ sense this is in my opinion the greatest.
+
+ Well said, Cephalus, I replied; but as concerning justice, what is
+ it?--to speak the truth and to pay your debts--no more than this? And
+ even to this are there not exceptions? Suppose that a friend when in
+ his right mind has deposited arms with me and he asks for them when he
+ is not in his right mind, ought I to give them back to him? No one
+ would say that I ought or that I should be right in doing so, any more
+ than they would say that I ought always to speak the truth to one who
+ is in his condition.
+
+ You are quite right, he replied.
+
+ But then, I said, speaking the truth and paying your debts is not a
+ correct definition of justice.
+
+ CEPHALUS - SOCRATES - POLEMARCHUS
+
+ Quite correct, Socrates, if Simonides is to be believed, said
+ Polemarchus interposing.
+
+ I fear, said Cephalus, that I must go now, for I have to look after the
+ sacrifices, and I hand over the argument to Polemarchus and the company.

+# "newname" to resolve it as both sides renaming it to the same new

+# but that may cancel out at the final merge stage".

+line_buffer API
+===============
+
+The line_buffer library provides a convenient interface for
+mostly-line-oriented input.
+
+Each line is not permitted to exceed 10000 bytes. The provided
+functions are not thread-safe or async-signal-safe, and like
+`fgets()`, they generally do not function correctly if interrupted
+by a signal without SA_RESTART set.
+
+Calling sequence
+----------------
+
+The calling program:
+
+ - initializes a `struct line_buffer` to LINE_BUFFER_INIT
+ - specifies a file to read with `buffer_init`
+ - processes input with `buffer_read_line`, `buffer_skip_bytes`,
+ and `buffer_copy_bytes`
+ - closes the file with `buffer_deinit`, perhaps to start over and
+ read another file.
+
+When finished, the caller can use `buffer_reset` to deallocate
+resources.
+
+Using temporary files
+---------------------
+
+Temporary files provide a place to store data that should not outlive
+the calling program. A program
+
+ - initializes a `struct line_buffer` to LINE_BUFFER_INIT
+ - requests a temporary file with `buffer_tmpfile_init`
+ - acquires an output handle by calling `buffer_tmpfile_rewind`
+ - uses standard I/O functions like `fprintf` and `fwrite` to fill
+ the temporary file
+ - declares writing is over with `buffer_tmpfile_prepare_to_read`
+ - can re-read what was written with `buffer_read_line`,
+ `buffer_copy_bytes`, and so on
+ - can reuse the temporary file by calling `buffer_tmpfile_rewind`
+ again
+ - removes the temporary file with `buffer_deinit`, perhaps to
+ reuse the line_buffer for some other file.
+
+When finished, the calling program can use `buffer_reset` to deallocate
+resources.
+
+Functions
+---------
+
+`buffer_init`, `buffer_fdinit`::
+ Open the named file or file descriptor for input.
+ buffer_init(buf, NULL) prepares to read from stdin.
+ On failure, returns -1 (with errno indicating the nature
+ of the failure).
+
+`buffer_deinit`::
+ Stop reading from the current file (closing it unless
+ it was stdin). Returns nonzero if `fclose` fails or
+ the error indicator was set.
+
+`buffer_read_line`::
+ Read a line and strip off the trailing newline.
+ On failure or end of file, returns NULL.
+
+`buffer_copy_bytes`::
+ Read `len` bytes of input and dump them to the standard output
+ stream. Returns early for error or end of file.
+
+`buffer_skip_bytes`::
+ Discards `len` bytes from the input stream (stopping early
+ if necessary because of an error or eof). Return value is
+ the number of bytes successfully read.
+
+`buffer_reset`::
+ Deallocates non-static buffers.

+string_pool API
+===============
+
+The string_pool API provides facilities for replacing strings
+with integer keys that can be more easily compared and stored.
+The facilities are designed so that one could teach Git without
+too much trouble to store the information needed for these keys to
+remain valid over multiple executions.
+
+Functions
+---------
+
+pool_intern::
+ Include a string in the string pool and get its key.
+ If that string is already in the pool, retrieves its
+ existing key.
+
+pool_fetch::
+ Retrieve the string associated to a given key.
+
+pool_tok_r::
+ Extract the key of the next token from a string.
+ Interface mimics strtok_r.
+
+pool_print_seq::
+ Print a sequence of strings named by key to a file, using the
+ specified delimiter to separate them.
+
+ If NULL (key ~0) appears in the sequence, the sequence ends
+ early.
+
+pool_tok_seq::
+ Split a string into tokens, storing the keys of segments
+ into a caller-provided array.
+
+ Unless sz is 0, the array will always be ~0-terminated.
+ If there is not enough room for all the tokens, the
+ array holds as many tokens as fit in the entries before
+ the terminating ~0. Return value is the index after the
+ last token, or sz if the tokens did not fit.
+
+pool_reset::
+ Deallocate storage for the string pool.

+Motivation
+==========
+
+Treaps provide a memory-efficient binary search tree structure.
+Insertion/deletion/search are about as about as fast in the average
+case as red-black trees and the chances of worst-case behavior are
+vanishingly small, thanks to (pseudo-)randomness. The bad worst-case
+behavior is a small price to pay, given that treaps are much simpler
+to implement.
+
+API
+===
+
+The trp API generates a data structure and functions to handle a
+large growing set of objects stored in a pool.
+
+The caller:
+
+. Specifies parameters for the generated functions with the
+ trp_gen(static, foo_, ...) macro.
+
+. Allocates a `struct trp_root` variable and sets it to {~0}.
+
+. Adds new nodes to the set using `foo_insert`. Any pointers
+ to existing nodes cannot be relied upon any more, so the caller
+ might retrieve them anew with `foo_pointer`.
+
+. Can find a specific item in the set using `foo_search`.
+
+. Can iterate over items in the set using `foo_first` and `foo_next`.
+
+. Can remove an item from the set using `foo_remove`.
+
+Example:
+
+----
+struct ex_node {
+ const char *s;
+ struct trp_node ex_link;
+};
+static struct trp_root ex_base = {~0};
+obj_pool_gen(ex, struct ex_node, 4096);
+trp_gen(static, ex_, struct ex_node, ex_link, ex, strcmp)
+struct ex_node *item;
+
+item = ex_pointer(ex_alloc(1));
+item->s = "hello";
+ex_insert(&ex_base, item);
+item = ex_pointer(ex_alloc(1));
+item->s = "goodbye";
+ex_insert(&ex_base, item);
+for (item = ex_first(&ex_base); item; item = ex_next(&ex_base, item))
+ printf("%s\n", item->s);
+----
+
+Functions
+---------
+
+trp_gen(attr, foo_, node_type, link_field, pool, cmp)::
+
+ Generate a type-specific treap implementation.
++
+. The storage class for generated functions will be 'attr' (e.g., `static`).
+. Generated function names are prefixed with 'foo_' (e.g., `treap_`).
+. Treap nodes will be of type 'node_type' (e.g., `struct treap_node`).
+ This type must be a struct with at least one `struct trp_node` field
+ to point to its children.
+. The field used to access child nodes will be 'link_field'.
+. All treap nodes must lie in the 'pool' object pool.
+. Treap nodes must be totally ordered by the 'cmp' relation, with the
+ following prototype:
++
+int (*cmp)(node_type \*a, node_type \*b)
++
+and returning a value less than, equal to, or greater than zero
+according to the result of comparison.
+
+node_type {asterisk}foo_insert(struct trp_root *treap, node_type \*node)::
+
+ Insert node into treap. If inserted multiple times,
+ a node will appear in the treap multiple times.
++
+The return value is the address of the node within the treap,
+which might differ from `node` if `pool_alloc` had to call
+`realloc` to expand the pool.
+
+void foo_remove(struct trp_root *treap, node_type \*node)::
+
+ Remove node from treap. Caller must ensure node is
+ present in treap before using this function.
+
+node_type *foo_search(struct trp_root \*treap, node_type \*key)::
+
+ Search for a node that matches key. If no match is found,
+ result is NULL.
+
+node_type *foo_nsearch(struct trp_root \*treap, node_type \*key)::
+
+ Like `foo_search`, but if the key is missing return what
+ would be key's successor, were key in treap (NULL if no
+ successor).
+
+node_type *foo_first(struct trp_root \*treap)::
+
+ Find the first item from the treap, in sorted order.
+
+node_type *foo_next(struct trp_root \*treap, node_type \*node)::
+
+ Find the next item.
