What's cooking in git.git (Nov 2020, #03; Wed, 11)
--------------------------------------------------

Here are the topics that have been cooking.  Commits prefixed with '-' are
only in 'seen' (formerly 'pu'---proposed updates) while commits prefixed
with '+' are in 'next'.  The ones marked with '.' do not appear in any of
the integration branches, but I am still holding onto them.

The fifth batch of topics have been merged to 'master'.

Copies of the source code to Git live in many repositories, and the
following is a list of the ones I push into.  Some repositories have
only a subset of branches.

With maint, master, next, seen, todo:

	git://git.kernel.org/pub/scm/git/git.git/
	git://repo.or.cz/alt-git.git/
	https://kernel.googlesource.com/pub/scm/git/git/
	https://github.com/git/git/

With all the integration branches and topics broken out:

	https://github.com/gitster/git/

Even though the preformatted documentation in HTML and man format
are not sources, they are published in these repositories for
convenience (replace "htmldocs" with "manpages" for the manual
pages):

	git://git.kernel.org/pub/scm/git/git-htmldocs.git/
	https://github.com/gitster/git-htmldocs.git/

  (merged to 'next' on 2020-11-09 at 09efe81b8b)

 clarified.


* jc/sequencer-stopped-sha-simplify (2020-10-21) 1 commit
  (merged to 'next' on 2020-11-02 at ba3dd9eaf4)
 + sequencer: tolerate abbreviated stopped-sha file

 Recently the format of an internal state file "rebase -i" uses has
 been tightened up for consistency, which would hurt those who start
 "rebase -i" with old git and then continue with new git.  Loosen
 the reader side a bit (which we may want to tighten again in a year
 or so).

  (merged to 'next' on 2020-11-10 at 384ace449d)
 + blame: silently ignore invalid ignore file objects

 "git blame --ignore-revs-file=<file>" learned to ignore a
 non-existent object name in the input, instead of complaining.

 Will merge to 'master'.


* jk/rev-parse-end-of-options (2020-11-10) 3 commits

 + rev-parse: handle --end-of-options
 + rev-parse: put all options under the "-" check
 + rev-parse: don't accept options after dashdash

 "git rev-parse" learned the "--end-of-options" to help scripts to
 safely take a parameter that is supposed to be a revision, e.g.
 "git rev-parse --verify -q --end-of-options $rev".

 Will merge to 'master'.

* js/add-i-color-fix (2020-11-11) 11 commits
 - add -i: verify in the tests that colors can be overridden
 - add -p: prefer color.diff.context over color.diff.plain
 - add -i (Perl version): include indentation in the colored header
 - add -i (built-in): use the same indentation as the Perl version
 - add -p (built-in): do not color the progress indicator separately
 - add -i (built-in): use correct names to load color.diff.* config
 - add -i (built-in): prevent the `reset` "color" from being configured
 - add -i: use `reset_color` consistently
 - add -p (built-in): imitate `xdl_format_hunk_hdr()` generating hunk headers

 - add -i (built-in): do show an error message for incorrect inputs

 "git add -i" failed to honor custom colors configured to show
 patches, which has been corrected.

 The last step may want to be polished further.

 - remote.c: fix handling of %(push:remoteref)

 The "%(push:remoteref)" placeholder in the "--format=" argument of
 "git format-patch" (and friends) only showed what got explicitly
 configured, not what ref at the receiving end would be updated when
 "git push" was used, as it ignored the default behaviour (e.g. update
 the same ref as the source).

 Discard for now.

* sj/untracked-files-in-submodule-directory-is-not-dirty (2020-10-26) 1 commit
 - diff: do not show submodule with untracked files as "-dirty"

 "git diff" showed a submodule working tree with untracked cruft as
 "Submodule commit <objectname>-dirty", but a natural expectation is
 that the "-dirty" indicator would align with "git describe --dirty",
 which does not consider having untracked files in the working tree
 as source of dirtiness.  The inconsistency has been fixed.

 Needs doc update and also adjusting "git status".

 Originally merged to 'next' on 2020-10-23

 "git fsck" and the corresponding check done during the transport
 learned to ensure that in-tree files like `.gitignore` and
 `.gitattributes` are not symbolic links.

 It seems that there are real projects with .gitignore recorded as
 symlinks, which may need to loosen the fsck setting.  Do we need
 to introduce a class that is separate from symlinked .gitmodules
 that probably is with potential consequences that is more grave?

 - commit-graph: return 64-bit generation number
 - commit-graph: consolidate fill_commit_graph_info

 The commit-graph learned to use corrected commit dates instead of
 the generation number to help topological revision traversal.

 "git push" learns a way to tell an object that it expects the other
 side to have and is usable as a common ancestor, which can be used
 by the other side to shrink its initial ref advertisement.
