+* Support for storing shorthands for remote URLs in "$GIT_COMMON_DIR/branches/"
+  and "$GIT_COMMON_DIR/remotes/" has been long superseded by storing remotes in
+  the repository configuration.
++
+The mechanism has originally been introduced in f170e4b39d ([PATCH] fetch/pull:
+short-hand notation for remote repositories., 2005-07-16) and was superseded by
+6687f8fea2 ([PATCH] Use .git/remote/origin, not .git/branches/origin.,
+2005-08-20), where we switched from ".git/branches/" to ".git/remotes/". That
+commit already mentions an upcoming deprecation of the ".git/branches/"
+directory, and starting with a1d4aa7424 (Add repository-layout document.,
+2005-09-01) we have also marked this layout as deprecated. Eventually we also
+started to migrate away from ".git/remotes/" in favor of config-based remotes,
+and we have marked the directory as legacy in 3d3d282146 (Documentation:
+Grammar correction, wording fixes and cleanup, 2011-08-23)
++
+As our documentation mentions, these directories are unlikely to be used in
+modern repositories and most users aren't even aware of these mechanisms. They
+have been deprecated for almost 20 years and 14 years respectively, and we are
+not aware of any active users that have complained about this deprecation.
+Furthermore, the ".git/branches/" directory is nowadays misleadingly named and
+may cause confusion as "branches" are almost exclusively used in the context of
+references.
++
+These features will be removed.
+
 == Superseded features that will not be deprecated

+Git v2.49 Release Notes
+=======================
+
+UI, Workflows & Features
+------------------------
+
+ * Completion script updates for zsh
+
+ * "git pack-objects" and its wrapper "git repack" learned an option
+   to use an alternative path-hash function to improve delta-base
+   selection to produce a packfile with deeper history than window
+   size.
+
+ * "git gc" learned the "--expire-to" option and passes it down to
+   underlying "git repack".
+
+ * "[help] autocorrect = 1" used to be a way to say "please wait for
+   0.1 second after suggesting a typofix of the command name before
+   running that command"; now it means "yes, if there is a plausible
+   typofix for the command name, please run it immediately".
+
+ * "git clone" learned to make a shallow clone for a single commit
+   that is not necessarily be at the tip of any branch.
+
+ * Lazy-loading missing files in a blobless clone on demand is costly
+   as it tends to be one-blob-at-a-time.  "git backfill" is introduced
+   to help bulk-download necessary files beforehand.
+
+ * "git push --atomic --porcelain" used to ignore failures from the
+   other side, losing the error status from the child process, which
+   has been corrected.
+
+ * "git rev-list --missing=" learned to accept "print-info" that gives
+   known details expected of the missing objects, like path and type.
+
+ * Comes with an updated "gitk".
+
+ * The documentation of "git commit" and "git rebase" now refer to
+   commit titles as such, not "subject".
+
+ * The value of "uname -s" is by default sent over the wire as a part
+   of the "version" capability.
+
+ * "git refs migrate" can optionally be told not to migrate the reflog.
+
+ * The netrc support (via the cURL library) for the HTTP transport has
+   been re-enabled.
+
+ * Removal of ".git/branches" and ".git/remotes" support in the
+   BreakingChanges document has been further clarified.
+
+ * What happens to submodules during merge has been documented in a
+   bit more detail.
+
+
+Performance, Internal Implementation, Development Support etc.
+--------------------------------------------------------------
+
+ * More -Wsign-compare fixes.
+
+ * meson-based build now supports the unsafe-sha1 build knob.
+
+ * The meson-based build procedure covers contrib/ and other places as
+   well.
+
+ * The code to check LSan results has been simplified and made more
+   robust.
+   (merge 164a2516eb jk/lsan-race-ignore-false-positive later to maint).
+
+ * More code paths have a repository passed through the callchain,
+   instead of assuming the primary the_repository object.
+
+ * Move a few more unit tests to the clar test framework.
+
+ * Introduce a new API to visit objects in batches based on a common
+   path, or by type.
+
+ * Following the procedure we established to introduce breaking
+   changes for Git 3.0, allow an early opt-in for removing support of
+   $GIT_DIR/branches/ and $GIT_DIR/remotes/ directories to configure
+   remotes.
+
+ * The code paths to interact with zlib has been cleaned up in
+   preparation for building with zlib-ng.
+
+ * Foreign language interface for Rust into our code base has been added.
+
+ * All the documentation .txt files have been renamed to .adoc to help
+   content aware editors.
+
+ * "git difftool" code clean-up.
+
+ * Rename processing in the recursive merge backend has seen a micro
+   optimization.
+
+ * The path.[ch] API takes an explicit repository parameter passed
+   throughout the callchain, instead of relying on the_repository
+   singleton instance.
+
+ * Large-object promisor protocol extension has been introduced.
+
+ * The editorconfig file is updated to tell us that bash scripts are
+   similar to general Bourne shell scripts.
+
+ * Meson-based build procedure forgot to build some docs, which has
+   been corrected.
+
+
+Fixes since v2.48
+-----------------
+
+ * "git submodule" learned various ways to spell the same option,
+   e.g. "--branch=B" can be spelled "--branch B" or "-bB".
+   (merge b86f0f9071 re/submodule-parse-opt later to maint).
+
+ * Tweak the help text used for the option value placeholders by
+   parse-options API so that translations can customize the "<>"
+   placeholder signal (e.g. "--option=<value>").
+   (merge 5b34dd08d0 as/long-option-help-i18n later to maint).
+
+ * CI jobs gave sporadic failures, which turns out that that the
+   object finalization code was giving an error when it did not have
+   to.
+   (merge d7fcbe2c56 ps/object-collision-check later to maint).
+

+   (merge 0b4f8afef6 ps/reftable-get-random-fix later to maint).
+
+ * A misconfigured "fsck.skiplist" configuration variable was not

+
+ * Extended SHA-1 expression parser did not work well when a branch

+   (merge 76baf97fa1 ak/instaweb-python-port-binding-fix later to maint).
+
+ * Document that it is insecure to use Personal Access Tokens, which

+
+ * "git branch --sort=..." and "git for-each-ref --format=... --sort=..."

+
+ * reflog entries for symbolic ref updates were broken, which has been
+   corrected.
+   (merge 3519492430 kn/reflog-symref-fix later to maint).
+
+ * The trace2 code was not prepared to show a configuration variable

+ * Fix bugs in an earlier attempt to fix "git refs migration".
+   (merge f11f0a5a2d kn/reflog-migration-fix-fix later to maint).
+
+ * The code path used when "git fetch" fetches from a bundle file
+   closed the same file descriptor twice, which sometimes broke things
+   unexpectedly when the file descriptor was reused, which has been

+   (merge 9a84794ad8 js/bundle-unbundle-fd-reuse-fix later to maint).
+
+ * "git init" to reinitialize a repository that already exists cannot
+   change the hash function and ref backends; such a request is
+   silently ignored now.
+   (merge 7e88640cd1 ps/setup-reinit-fixes later to maint).
+
+ * "git apply" internally uses unsigned long for line numbers and uses
+   strtoul() to parse numbers on the hunk headers.  It however forgot
+   to check parse errors.
+   (merge a206058fda pw/apply-ulong-overflow-check later to maint).

+
+ * Going into a secondary worktree and asking "is the main worktree

+   has been corrected.
+   (merge 93dc16483a bf/fetch-set-head-fix later to maint).
+
+ * A thunderbird helper script lost its bashism.
+   (merge 59d26bd961 bc/contrib-thunderbird-patch-inline-fix later to maint).

+
+ * "git merge-tree --stdin" has been improved (including a workaround
+   for a deadlock).
+   (merge 6a9ae81015 pw/merge-tree-stdin-deadlock-fix later to maint).
+
+ * Correct the default target in Documentation/Makefile, and

+trailer.separators::
+	This option tells which characters are recognized as trailer
+	separators. By default only ':' is recognized as a trailer
+	separator, except that '=' is always accepted on the command
+	line for compatibility with other git commands.
++
+The first character given by this option will be the default character
+used when another separator is not specified in the config for this
+trailer.
++
+For example, if the value for this option is "%=$", then only lines
+using the format '<key><sep><value>' with <sep> containing '%', '='
+or '$' and then spaces will be considered trailers. And '%' will be
+the default separator used, so by default trailers will appear like:
+'<key>% <value>' (one percent sign and one space will appear between
+the key and the value).
+
+trailer.where::
+	This option tells where a new trailer will be added.
++
+This can be `end`, which is the default, `start`, `after` or `before`.
++
+If it is `end`, then each new trailer will appear at the end of the
+existing trailers.
++
+If it is `start`, then each new trailer will appear at the start,
+instead of the end, of the existing trailers.
++
+If it is `after`, then each new trailer will appear just after the
+last trailer with the same <key>.
++
+If it is `before`, then each new trailer will appear just before the
+first trailer with the same <key>.
+
+trailer.ifexists::
+	This option makes it possible to choose what action will be
+	performed when there is already at least one trailer with the
+	same <key> in the input.
++
+The valid values for this option are: `addIfDifferentNeighbor` (this
+is the default), `addIfDifferent`, `add`, `replace` or `doNothing`.
++
+With `addIfDifferentNeighbor`, a new trailer will be added only if no
+trailer with the same (<key>, <value>) pair is above or below the line
+where the new trailer will be added.
++
+With `addIfDifferent`, a new trailer will be added only if no trailer
+with the same (<key>, <value>) pair is already in the input.
++
+With `add`, a new trailer will be added, even if some trailers with
+the same (<key>, <value>) pair are already in the input.
++
+With `replace`, an existing trailer with the same <key> will be
+deleted and the new trailer will be added. The deleted trailer will be
+the closest one (with the same <key>) to the place where the new one
+will be added.
++
+With `doNothing`, nothing will be done; that is no new trailer will be
+added if there is already one with the same <key> in the input.
+
+trailer.ifmissing::
+	This option makes it possible to choose what action will be
+	performed when there is not yet any trailer with the same
+	<key> in the input.
++
+The valid values for this option are: `add` (this is the default) and
+`doNothing`.
++
+With `add`, a new trailer will be added.
++
+With `doNothing`, nothing will be done.
+
+trailer.<keyAlias>.key::
+	Defines a <keyAlias> for the <key>. The <keyAlias> must be a
+	prefix (case does not matter) of the <key>. For example, in `git
+	config trailer.ack.key "Acked-by"` the "Acked-by" is the <key> and
+	the "ack" is the <keyAlias>. This configuration allows the shorter
+	`--trailer "ack:..."` invocation on the command line using the "ack"
+	<keyAlias> instead of the longer `--trailer "Acked-by:..."`.
++
+At the end of the <key>, a separator can appear and then some
+space characters. By default the only valid separator is ':',
+but this can be changed using the `trailer.separators` config
+variable.
++
+If there is a separator in the key, then it overrides the default
+separator when adding the trailer.
+
+trailer.<keyAlias>.where::
+	This option takes the same values as the 'trailer.where'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <keyAlias>.
+
+trailer.<keyAlias>.ifexists::
+	This option takes the same values as the 'trailer.ifexists'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <keyAlias>.
+
+trailer.<keyAlias>.ifmissing::
+	This option takes the same values as the 'trailer.ifmissing'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <keyAlias>.
+
+trailer.<keyAlias>.command::
+	Deprecated in favor of 'trailer.<keyAlias>.cmd'.
+	This option behaves in the same way as 'trailer.<keyAlias>.cmd', except
+	that it doesn't pass anything as argument to the specified command.
+	Instead the first occurrence of substring $ARG is replaced by the
+	<value> that would be passed as argument.
++
+Note that $ARG in the user's command is
+only replaced once and that the original way of replacing $ARG is not safe.
++
+When both 'trailer.<keyAlias>.cmd' and 'trailer.<keyAlias>.command' are given
+for the same <keyAlias>, 'trailer.<keyAlias>.cmd' is used and
+'trailer.<keyAlias>.command' is ignored.
+
+trailer.<keyAlias>.cmd::
+	This option can be used to specify a shell command that will be called
+	once to automatically add a trailer with the specified <keyAlias>, and then
+	called each time a '--trailer <keyAlias>=<value>' argument is specified to
+	modify the <value> of the trailer that this option would produce.
++
+When the specified command is first called to add a trailer
+with the specified <keyAlias>, the behavior is as if a special
+'--trailer <keyAlias>=<value>' argument was added at the beginning
+of the "git interpret-trailers" command, where <value>
+is taken to be the standard output of the command with any
+leading and trailing whitespace trimmed off.
++
+If some '--trailer <keyAlias>=<value>' arguments are also passed
+on the command line, the command is called again once for each
+of these arguments with the same <keyAlias>. And the <value> part
+of these arguments, if any, will be passed to the command as its
+first argument. This way the command can produce a <value> computed
+from the <value> passed in the '--trailer <keyAlias>=<value>' argument.

+NAME
+----
+git-backfill - Download missing objects in a partial clone
+
+
+SYNOPSIS
+--------
+[synopsis]
+git backfill [--min-batch-size=<n>] [--[no-]sparse]
+
+DESCRIPTION
+-----------
+
+Blobless partial clones are created using `git clone --filter=blob:none`
+and then configure the local repository such that the Git client avoids
+downloading blob objects unless they are required for a local operation.
+This initially means that the clone and later fetches download reachable
+commits and trees but no blobs. Later operations that change the `HEAD`
+pointer, such as `git checkout` or `git merge`, may need to download
+missing blobs in order to complete their operation.
+
+In the worst cases, commands that compute blob diffs, such as `git blame`,
+become very slow as they download the missing blobs in single-blob
+requests to satisfy the missing object as the Git command needs it. This
+leads to multiple download requests and no ability for the Git server to
+provide delta compression across those objects.
+
+The `git backfill` command provides a way for the user to request that
+Git downloads the missing blobs (with optional filters) such that the
+missing blobs representing historical versions of files can be downloaded
+in batches. The `backfill` command attempts to optimize the request by
+grouping blobs that appear at the same path, hopefully leading to good
+delta compression in the packfile sent by the server.
+
+In this way, `git backfill` provides a mechanism to break a large clone
+into smaller chunks. Starting with a blobless partial clone with `git
+clone --filter=blob:none` and then running `git backfill` in the local
+repository provides a way to download all reachable objects in several
+smaller network calls than downloading the entire repository at clone
+time.
+
+By default, `git backfill` downloads all blobs reachable from the `HEAD`
+commit. This set can be restricted or expanded using various options.
+
+THIS COMMAND IS EXPERIMENTAL. ITS BEHAVIOR MAY CHANGE IN THE FUTURE.
+
+
+OPTIONS
+-------
+
+`--min-batch-size=<n>`::
+	Specify a minimum size for a batch of missing objects to request
+	from the server. This size may be exceeded by the last set of
+	blobs seen at a given path. The default minimum batch size is
+	50,000.
+
+`--[no-]sparse`::
+	Only download objects if they appear at a path that matches the
+	current sparse-checkout. If the sparse-checkout feature is enabled,
+	then `--sparse` is assumed and can be disabled with `--no-sparse`.

+PERSONAL ACCESS TOKENS
+----------------------
+
+Some remotes accept personal access tokens, which are randomly
+generated and hard to memorise. They typically have a lifetime of weeks
+or months.
+
+git-credential-cache is inherently unsuitable for persistent storage of
+personal access tokens. The credential will be forgotten after the cache
+timeout. Even if you configure a long timeout, credentials will be
+forgotten if the daemon dies.
+
+To avoid frequently regenerating personal access tokens, configure a
+credential helper with persistent storage. Alternatively, configure an
+OAuth credential helper to generate credentials automatically. See
+linkgit:gitcredentials[7], sections "Available helpers" and "OAuth".

 CONFIGURATION VARIABLES
 -----------------------
 
-trailer.separators::
-	This option tells which characters are recognized as trailer
-	separators. By default only ':' is recognized as a trailer
-	separator, except that '=' is always accepted on the command
-	line for compatibility with other git commands.
-+
-The first character given by this option will be the default character
-used when another separator is not specified in the config for this
-trailer.
-+
-For example, if the value for this option is "%=$", then only lines
-using the format '<key><sep><value>' with <sep> containing '%', '='
-or '$' and then spaces will be considered trailers. And '%' will be
-the default separator used, so by default trailers will appear like:
-'<key>% <value>' (one percent sign and one space will appear between
-the key and the value).
+include::includes/cmd-config-section-all.adoc[]
 
-trailer.where::
-	This option tells where a new trailer will be added.
-+
-This can be `end`, which is the default, `start`, `after` or `before`.
-+
-If it is `end`, then each new trailer will appear at the end of the
-existing trailers.
-+
-If it is `start`, then each new trailer will appear at the start,
-instead of the end, of the existing trailers.
-+
-If it is `after`, then each new trailer will appear just after the
-last trailer with the same <key>.
-+
-If it is `before`, then each new trailer will appear just before the
-first trailer with the same <key>.
-
-trailer.ifexists::
-	This option makes it possible to choose what action will be
-	performed when there is already at least one trailer with the
-	same <key> in the input.
-+
-The valid values for this option are: `addIfDifferentNeighbor` (this
-is the default), `addIfDifferent`, `add`, `replace` or `doNothing`.
-+
-With `addIfDifferentNeighbor`, a new trailer will be added only if no
-trailer with the same (<key>, <value>) pair is above or below the line
-where the new trailer will be added.
-+
-With `addIfDifferent`, a new trailer will be added only if no trailer
-with the same (<key>, <value>) pair is already in the input.
-+
-With `add`, a new trailer will be added, even if some trailers with
-the same (<key>, <value>) pair are already in the input.
-+
-With `replace`, an existing trailer with the same <key> will be
-deleted and the new trailer will be added. The deleted trailer will be
-the closest one (with the same <key>) to the place where the new one
-will be added.
-+
-With `doNothing`, nothing will be done; that is no new trailer will be
-added if there is already one with the same <key> in the input.
-
-trailer.ifmissing::
-	This option makes it possible to choose what action will be
-	performed when there is not yet any trailer with the same
-	<key> in the input.
-+
-The valid values for this option are: `add` (this is the default) and
-`doNothing`.
-+
-With `add`, a new trailer will be added.
-+
-With `doNothing`, nothing will be done.
-
-trailer.<keyAlias>.key::
-	Defines a <keyAlias> for the <key>. The <keyAlias> must be a
-	prefix (case does not matter) of the <key>. For example, in `git
-	config trailer.ack.key "Acked-by"` the "Acked-by" is the <key> and
-	the "ack" is the <keyAlias>. This configuration allows the shorter
-	`--trailer "ack:..."` invocation on the command line using the "ack"
-	<keyAlias> instead of the longer `--trailer "Acked-by:..."`.
-+
-At the end of the <key>, a separator can appear and then some
-space characters. By default the only valid separator is ':',
-but this can be changed using the `trailer.separators` config
-variable.
-+
-If there is a separator in the key, then it overrides the default
-separator when adding the trailer.
-
-trailer.<keyAlias>.where::
-	This option takes the same values as the 'trailer.where'
-	configuration variable and it overrides what is specified by
-	that option for trailers with the specified <keyAlias>.
-
-trailer.<keyAlias>.ifexists::
-	This option takes the same values as the 'trailer.ifexists'
-	configuration variable and it overrides what is specified by
-	that option for trailers with the specified <keyAlias>.
-
-trailer.<keyAlias>.ifmissing::
-	This option takes the same values as the 'trailer.ifmissing'
-	configuration variable and it overrides what is specified by
-	that option for trailers with the specified <keyAlias>.
-
-trailer.<keyAlias>.command::
-	Deprecated in favor of 'trailer.<keyAlias>.cmd'.
-	This option behaves in the same way as 'trailer.<keyAlias>.cmd', except
-	that it doesn't pass anything as argument to the specified command.
-	Instead the first occurrence of substring $ARG is replaced by the
-	<value> that would be passed as argument.
-+
-Note that $ARG in the user's command is
-only replaced once and that the original way of replacing $ARG is not safe.
-+
-When both 'trailer.<keyAlias>.cmd' and 'trailer.<keyAlias>.command' are given
-for the same <keyAlias>, 'trailer.<keyAlias>.cmd' is used and
-'trailer.<keyAlias>.command' is ignored.
-
-trailer.<keyAlias>.cmd::
-	This option can be used to specify a shell command that will be called
-	once to automatically add a trailer with the specified <keyAlias>, and then
-	called each time a '--trailer <keyAlias>=<value>' argument is specified to
-	modify the <value> of the trailer that this option would produce.
-+
-When the specified command is first called to add a trailer
-with the specified <keyAlias>, the behavior is as if a special
-'--trailer <keyAlias>=<value>' argument was added at the beginning
-of the "git interpret-trailers" command, where <value>
-is taken to be the standard output of the command with any
-leading and trailing whitespace trimmed off.
-+
-If some '--trailer <keyAlias>=<value>' arguments are also passed
-on the command line, the command is called again once for each
-of these arguments with the same <keyAlias>. And the <value> part
-of these arguments, if any, will be passed to the command as its
-first argument. This way the command can produce a <value> computed
-from the <value> passed in the '--trailer <keyAlias>=<value>' argument.

 	Restrict delta matches based on "islands". See DELTA ISLANDS

+--name-hash-version=<n>::
+	While performing delta compression, Git groups objects that may be
+	similar based on heuristics using the path to that object. While
+	grouping objects by an exact path match is good for paths with
+	many versions, there are benefits for finding delta pairs across
+	different full paths. Git collects objects by type and then by a
+	"name hash" of the path and then by size, hoping to group objects
+	that will compress well together.
++
+The default name hash version is `1`, which prioritizes hash locality by
+considering the final bytes of the path as providing the maximum magnitude
+to the hash function. This version excels at distinguishing short paths
+and finding renames across directories. However, the hash function depends
+primarily on the final 16 bytes of the path. If there are many paths in
+the repo that have the same final 16 bytes and differ only by parent
+directory, then this name-hash may lead to too many collisions and cause
+poor results. At the moment, this version is required when writing
+reachability bitmap files with `--write-bitmap-index`.
++
+The name hash version `2` has similar locality features as version `1`,
+except it considers each path component separately and overlays the hashes
+with a shift. This still prioritizes the final bytes of the path, but also
+"salts" the lower bits of the hash using the parent directory names. This
+method allows for some of the locality benefits of version `1` while
+breaking most of the collisions from a similarly-named file appearing in
+many different directories. At the moment, this version is not allowed
+when writing reachability bitmap files with `--write-bitmap-index` and it
+will be automatically changed to version `1`.

+Options trump configuration and environment
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When there is a configuration variable or an environment variable
+that tweak the behaviour of an aspect of a Git command, and also a
+command line option that tweaks the same, the command line option
+overrides what the configuration and/or environment variable say.
+
+For example, the `user.name` configuration variable is used to
+specify the human-readable name used by the `git commit` command to
+record the author and the committer name in a newly created commit.
+The `GIT_AUTHOR_NAME` environment variable, if set, takes precedence
+when deciding what author name to record.  The `--author=<author>`
+command line option of the `git commit` command, when given, takes
+precedence over these two sources of information.

+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The server may advertise some promisor remotes it is using or knows
+about to a client which may want to use them as its promisor remotes,
+instead of this repository. In this case <pr-infos> should be of the
+form:
+
+	pr-infos = pr-info | pr-infos ";" pr-info
+
+	pr-info = "name=" pr-name | "name=" pr-name "," "url=" pr-url
+
+where `pr-name` is the urlencoded name of a promisor remote, and
+`pr-url` the urlencoded URL of that promisor remote.
+
+In this case, if the client decides to use one or more promisor
+remotes the server advertised, it can reply with
+"promisor-remote=<pr-names>" where <pr-names> should be of the form:
+
+	pr-names = pr-name | pr-names ";" pr-name
+
+where `pr-name` is the urlencoded name of a promisor remote the server
+advertised and the client accepts.
+
+Note that, everywhere in this document, `pr-name` MUST be a valid
+remote name, and the ';' and ',' characters MUST be encoded if they
+appear in `pr-name` or `pr-url`.
+
+If the server doesn't know any promisor remote that could be good for
+a client to use, or prefers a client not to use any promisor remote it
+uses or knows about, it shouldn't advertise the "promisor-remote"
+capability at all.
+
+In this case, or if the client doesn't want to use any promisor remote
+the server advertised, the client shouldn't advertise the
+"promisor-remote" capability at all in its reply.
+
+The "promisor.advertise" and "promisor.acceptFromServer" configuration
+options can be used on the server and client side to control what they
+advertise or accept respectively. See the documentation of these
+configuration options for more information.
+
+Note that in the future it would be nice if the "promisor-remote"
+protocol capability could be used by the server, when responding to
+`git fetch` or `git clone`, to advertise better-connected remotes that
+the client can use as promisor remotes, instead of this repository, so
+that the client can lazily fetch objects from these other
+better-connected remotes. This would require the server to omit in its
+response the objects available on the better-connected remotes that
+the client has accepted. This hasn't been implemented yet though. So
+for now this "promisor-remote" capability is useful only when the
+server advertises some promisor remotes it already uses to borrow
+objects from.

+Path-Walk API
+=============
+
+The path-walk API is used to walk reachable objects, but to visit objects
+in batches based on a common path they appear in, or by type.
+
+For example, all reachable commits are visited in a group. All tags are
+visited in a group. Then, all root trees are visited. At some point, all
+blobs reachable via a path `my/dir/to/A` are visited. When there are
+multiple paths possible to reach the same object, then only one of those
+paths is used to visit the object.
+
+Basics
+------
+
+To use the path-walk API, include `path-walk.h` and call
+`walk_objects_by_path()` with a customized `path_walk_info` struct. The
+struct is used to set all of the options for how the walk should proceed.
+Let's dig into the different options and their use.
+
+`path_fn` and `path_fn_data`::
+	The most important option is the `path_fn` option, which is a
+	function pointer to the callback that can execute logic on the
+	object IDs for objects grouped by type and path. This function
+	also receives a `data` value that corresponds to the
+	`path_fn_data` member, for providing custom data structures to
+	this callback function.
+
+`revs`::
+	To configure the exact details of the reachable set of objects,
+	use the `revs` member and initialize it using the revision
+	machinery in `revision.h`. Initialize `revs` using calls such as
+	`setup_revisions()` or `parse_revision_opt()`. Do not call
+	`prepare_revision_walk()`, as that will be called within
+	`walk_objects_by_path()`.
++
+It is also important that you do not specify the `--objects` flag for the
+`revs` struct. The revision walk should only be used to walk commits, and
+the objects will be walked in a separate way based on those starting
+commits.
+
+`commits`, `blobs`, `trees`, `tags`::
+	By default, these members are enabled and signal that the path-walk
+	API should call the `path_fn` on objects of these types. Specialized
+	applications could disable some options to make it simpler to walk
+	the objects or to have fewer calls to `path_fn`.
++
+While it is possible to walk only commits in this way, consumers would be
+better off using the revision walk API instead.
+
+`prune_all_uninteresting`::
+	By default, all reachable paths are emitted by the path-walk API.
+	This option allows consumers to declare that they are not
+	interested in paths where all included objects are marked with the
+	`UNINTERESTING` flag. This requires using the `boundary` option in
+	the revision walk so that the walk emits commits marked with the
+	`UNINTERESTING` flag.
+
+`pl`::
+	This pattern list pointer allows focusing the path-walk search to
+	a set of patterns, only emitting paths that match the given
+	patterns. See linkgit:gitignore[5] or
+	linkgit:git-sparse-checkout[1] for details about pattern lists.
+	When the pattern list uses cone-mode patterns, then the path-walk
+	API can prune the set of paths it walks to improve performance.
+
+Examples
+--------
+
+See example usages in:
+	`t/helper/test-path-walk.c`,
+	`builtin/backfill.c`

+Large Object Promisors
+======================
+
+Since Git has been created, users have been complaining about issues
+with storing large files in Git. Some solutions have been created to
+help, but they haven't helped much with some issues.
+
+Git currently supports multiple promisor remotes, which could help
+with some of these remaining issues, but it's very hard to use them to
+help, because a number of important features are missing.
+
+The goal of the effort described in this document is to add these
+important features.
+
+We will call a "Large Object Promisor", or "LOP" in short, a promisor
+remote which is used to store only large blobs and which is separate
+from the main remote that should store the other Git objects and the
+rest of the repos.
+
+By extension, we will also call "Large Object Promisor", or LOP, the
+effort described in this document to add a set of features to make it
+easier to handle large blobs/files in Git by using LOPs.
+
+This effort aims to especially improve things on the server side, and
+especially for large blobs that are already compressed in a binary
+format.
+
+This effort aims to provide an alternative to Git LFS
+(https://git-lfs.com/) and similar tools like git-annex
+(https://git-annex.branchable.com/) for handling large files, even
+though a complete alternative would very likely require other efforts
+especially on the client side, where it would likely help to implement
+a new object representation for large blobs as discussed in:
+
+https://lore.kernel.org/git/xmqqbkdometi.fsf@gitster.g/

+  would require changes in different parts of Git than this effort.
++
+So we don't pretend to fully replace Git LFS with only this effort,
+but we nevertheless believe that it can significantly improve the
+current situation on the server side, and that other separate
+efforts could also improve the situation on the client side.
+
+- In the same way, we are not going to discuss all the possible ways
+  to implement a LOP or their underlying object storage, or to
+  optimize how LOP works.
++
+Our opinion is that the simplest solution for now is for LOPs to use
+object storage through a remote helper (see section II.2 below for
+more details) to store their objects. So we consider that this is the
+default implementation. If there are improvements on top of this,
+that's great, but our opinion is that such improvements are not
+necessary for LOPs to already be useful. Such improvements are likely
+a different technical topic, and can be taken care of separately
+anyway.
++
+So in particular we are not going to discuss pluggable ODBs or other
+object database backends that could chunk large blobs, dedup the
+chunks and store them efficiently. Sure, that would be a nice
+improvement to store large blobs on the server side, but we believe
+it can just be a separate effort as it's also not technically very
+related to this effort.
++
+We are also not going to discuss data transfer improvements between
+LOPs and clients or servers. Sure, there might be some easy and very
+effective optimizations there (as we know that objects on LOPs are
+very likely incompressible and not deltifying well), but this can be
+dealt with separately in a separate effort.
+
+In other words, the goal of this document is not to talk about all the
+possible ways to optimize how Git could handle large blobs, but to
+describe how a LOP based solution can already work well and alleviate
+a number of current issues in the context of Git clients and servers
+sharing Git objects.
+
+Even if LOPs are used not very efficiently, they can still be useful
+and worth using in some cases, as we will see in more details
+later in this document:
+
+  - they can make it simpler for clients to use promisor remotes and
+    therefore avoid fetching a lot of large blobs they might not need
+    locally,
+
+  - they can make it significantly cheaper or easier for servers to
+    host a significant part of the current repository content, and
+    even more to host content with larger blobs or more large blobs
+    than currently.
+
+I) Issues with the current situation
+------------------------------------
+
+- Some statistics made on GitLab repos have shown that more than 75%
+  of the disk space is used by blobs that are larger than 1MB and
+  often in a binary format.
+
+- So even if users could use Git LFS or similar tools to store a lot
+  of large blobs out of their repos, it's a fact that in practice they
+  don't do it as much as they probably should.
+
+- On the server side ideally, the server should be able to decide for
+  itself how it stores things. It should not depend on users deciding
+  to use tools like Git LFS on some blobs or not.
+
+- It's much more expensive to store large blobs that don't delta
+  compress well on regular fast seeking drives (like SSDs) than on
+  object storage (like Amazon S3 or GCP Buckets). Using fast drives
+  for regular Git repos makes sense though, as serving regular Git
+  content (blobs containing text or code) needs drives where seeking
+  is fast, but the content is relatively small. On the other hand,
+  object storage for Git LFS blobs makes sense as seeking speed is not
+  as important when dealing with large files, while costs are more
+  important. So the fact that users don't use Git LFS or similar tools
+  for a significant number of large blobs has likely some bad
+  consequences on the cost of repo storage for most Git hosting
+  platforms.
+
+- Having large blobs handled in the same way as other blobs and Git
+  objects in Git repos instead of on object storage also has a cost in
+  increased memory and CPU usage, and therefore decreased performance,
+  when creating packfiles. (This is because Git tries to use delta
+  compression or zlib compression which is unlikely to work well on
+  already compressed binary content.) So it's not just a storage cost
+  increase.
+
+- When a large blob has been committed into a repo, it might not be
+  possible to remove this blob from the repo without rewriting
+  history, even if the user then decides to use Git LFS or a similar
+  tool to handle it.
+
+- In fact Git LFS and similar tools are not very flexible in letting
+  users change their minds about the blobs they should handle or not.
+
+- Even when users are using Git LFS or similar tools, they are often
+  complaining that these tools require significant effort to set up,
+  learn and use correctly.
+
+II) Main features of the "Large Object Promisors" solution
+----------------------------------------------------------
+
+The main features below should give a rough overview of how the
+solution may work. Details about needed elements can be found in
+following sections.
+
+Even if each feature below is very useful for the full solution, it is
+very likely to be also useful on its own in some cases where the full
+solution is not required. However, we'll focus primarily on the big
+picture here.
+
+Also each feature doesn't need to be implemented entirely in Git
+itself. Some could be scripts, hooks or helpers that are not part of
+the Git repo. It would be helpful if those could be shared and
+improved on collaboratively though. So we want to encourage sharing
+them.
+
+1) Large blobs are stored on LOPs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Large blobs should be stored on special promisor remotes that we will
+call "Large Object Promisors" or LOPs. These LOPs should be additional
+remotes dedicated to contain large blobs especially those in binary
+format. They should be used along with main remotes that contain the
+other objects.
+
+Note 1
+++++++
+
+To clarify, a LOP is a normal promisor remote, except that:
+
+- it should store only large blobs,
+
+- it should be separate from the main remote, so that the main remote
+  can focus on serving other objects and the rest of the repos (see
+  feature 4) below) and can use the LOP as a promisor remote for
+  itself.
+
+Note 2
+++++++
+
+Git already makes it possible for a main remote to also be a promisor
+remote storing both regular objects and large blobs for a client that
+clones from it with a filter on blob size. But here we explicitly want
+to avoid that.
+
+Rationale
++++++++++
+
+LOPs aim to be good at handling large blobs while main remotes are
+already good at handling other objects.
+
+Implementation
+++++++++++++++
+
+Git already has support for multiple promisor remotes, see
+link:partial-clone.html#using-many-promisor-remotes[the partial clone documentation].
+
+Also, Git already has support for partial clone using a filter on the
+size of the blobs (with `git clone --filter=blob:limit=<size>`).  Most
+of the other main features below are based on these existing features
+and are about making them easy and efficient to use for the purpose of
+better handling large blobs.
+
+2) LOPs can use object storage
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+LOPs can be implemented using object storage, like an Amazon S3 or GCP
+Bucket or MinIO (which is open source under the GNU AGPLv3 license) to
+actually store the large blobs, and can be accessed through a Git
+remote helper (see linkgit:gitremote-helpers[7]) which makes the
+underlying object storage appear like a remote to Git.
+
+Note
+++++
+
+A LOP can be a promisor remote accessed using a remote helper by
+both some clients and the main remote.
+
+Rationale
++++++++++
+
+This looks like the simplest way to create LOPs that can cheaply
+handle many large blobs.
+
+Implementation
+++++++++++++++
+
+Remote helpers are quite easy to write as shell scripts, but it might
+be more efficient and maintainable to write them using other languages
+like Go.
+
+Some already exist under open source licenses, for example:
+
+  - https://github.com/awslabs/git-remote-s3
+  - https://gitlab.com/eric.p.ju/git-remote-gs
+
+Other ways to implement LOPs are certainly possible, but the goal of
+this document is not to discuss how to best implement a LOP or its
+underlying object storage (see the "0) Non goals" section above).
+
+3) LOP object storage can be Git LFS storage
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The underlying object storage that a LOP uses could also serve as
+storage for large files handled by Git LFS.
+
+Rationale
++++++++++
+
+This would simplify the server side if it wants to both use a LOP and
+act as a Git LFS server.
+
+4) A main remote can offload to a LOP with a configurable threshold
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On the server side, a main remote should have a way to offload to a
+LOP all its blobs with a size over a configurable threshold.
+
+Rationale
++++++++++
+
+This makes it easy to set things up and to clean things up. For
+example, an admin could use this to manually convert a repo not using
+LOPs to a repo using a LOP. On a repo already using a LOP but where
+some users would sometimes push large blobs, a cron job could use this
+to regularly make sure the large blobs are moved to the LOP.
+
+Implementation
+++++++++++++++
+
+Using something based on `git repack --filter=...` to separate the
+blobs we want to offload from the other Git objects could be a good
+idea. The missing part is to connect to the LOP, check if the blobs we
+want to offload are already there and if not send them.
+
+5) A main remote should try to remain clean from large blobs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A main remote should try to avoid containing a lot of oversize
+blobs. For that purpose, it should offload as needed to a LOP and it
+should have ways to prevent oversize blobs to be fetched, and also
+perhaps pushed, into it.
+
+Rationale
++++++++++
+
+A main remote containing many oversize blobs would defeat the purpose
+of LOPs.
+
+Implementation
+++++++++++++++
+
+The way to offload to a LOP discussed in 4) above can be used to
+regularly offload oversize blobs. About preventing oversize blobs from
+being fetched into the repo see 6) below. About preventing oversize
+blob pushes, a pre-receive hook could be used.
+
+Also there are different scenarios in which large blobs could get
+fetched into the main remote, for example:
+
+- A client that doesn't implement the "promisor-remote" protocol
+  (described in 6) below) clones from the main remote.
+
+- The main remote gets a request for information about a large blob
+  and is not able to get that information without fetching the blob
+  from the LOP.
+
+It might not be possible to completely prevent all these scenarios
+from happening. So the goal here should be to implement features that
+make the fetching of large blobs less likely. For example adding a
+`remote-object-info` command in the `git cat-file --batch` protocol
+and its variants might make it possible for a main repo to respond to
+some requests about large blobs without fetching them.
+
+6) A protocol negotiation should happen when a client clones
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When a client clones from a main repo, there should be a protocol
+negotiation so that the server can advertise one or more LOPs and so
+that the client and the server can discuss if the client could
+directly use a LOP the server is advertising. If the client and the
+server can agree on that, then the client would be able to get the
+large blobs directly from the LOP and the server would not need to
+fetch those blobs from the LOP to be able to serve the client.
+
+Note
+++++
+
+For fetches instead of clones, a protocol negotiation might not always
+happen, see the "What about fetches?" FAQ entry below for details.
+
+Rationale
++++++++++
+
+Security, configurability and efficiency of setting things up.
+
+Implementation
+++++++++++++++
+
+A "promisor-remote" protocol v2 capability looks like a good way to
+implement this. The way the client and server use this capability
+could be controlled by configuration variables.
+
+Information that the server could send to the client through that
+protocol could be things like: LOP name, LOP URL, filter-spec (for
+example `blob:limit=<size>`) or just size limit that should be used as
+a filter when cloning, token to be used with the LOP, etc.
+
+7) A client can offload to a LOP
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When a client is using a LOP that is also a LOP of its main remote,
+the client should be able to offload some large blobs it has fetched,
+but might not need anymore, to the LOP.
+
+Note
+++++
+
+It might depend on the context if it should be OK or not for clients
+to offload large blobs they have created, instead of fetched, directly
+to the LOP without the main remote checking them in some ways
+(possibly using hooks or other tools).
+
+This should be discussed and refined when we get closer to
+implementing this feature.
+
+Rationale
++++++++++
+
+On the client, the easiest way to deal with unneeded large blobs is to
+offload them.
+
+Implementation
+++++++++++++++
+
+This is very similar to what 4) above is about, except on the client
+side instead of the server side. So a good solution to 4) could likely
+be adapted to work on the client side too.
+
+There might be some security issues here, as there is no negotiation,
+but they might be mitigated if the client can reuse a token it got
+when cloning (see 6) above). Also if the large blobs were fetched from
+a LOP, it is likely, and can easily be confirmed, that the LOP still
+has them, so that they can just be removed from the client.
+
+III) Benefits of using LOPs
+---------------------------
+
+Many benefits are related to the issues discussed in "I) Issues with
+the current situation" above:
+
+- No need to rewrite history when deciding which blobs are worth
+  handling separately than other objects, or when moving or removing
+  the threshold.
+
+- If the protocol between client and server is developed and secured
+  enough, then many details might be setup on the server side only and
+  all the clients could then easily get all the configuration
+  information and use it to set themselves up mostly automatically.
+
+- Storage costs benefits on the server side.
+
+- Reduced memory and CPU needs on main remotes on the server side.
+
+- Reduced storage needs on the client side.
+
+IV) FAQ
+-------
+
+What about using multiple LOPs on the server and client side?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+That could perhaps be useful in some cases, but for now it's more
+likely that in most cases a single LOP will be advertised by the
+server and should be used by the client.
+
+A case where it could be useful for a server to advertise multiple
+LOPs is if a LOP is better for some users while a different LOP is
+better for other users. For example some clients might have a better
+connection to a LOP than others.
+
+In those cases it's the responsibility of the server to have some
+documentation to help clients. It could say for example something like
+"Users in this part of the world might want to pick only LOP A as it
+is likely to be better connected to them, while users in other parts
+of the world should pick only LOP B for the same reason."
+
+When should we trust or not trust the LOPs advertised by the server?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In some contexts, like in corporate setup where the server and all the
+clients are parts of an internal network in a company where admins
+have all the rights on every system, it's OK, and perhaps even a good
+thing, if the clients fully trust the server, as it can help ensure
+that all the clients are on the same page.
+
+There are also contexts in which clients trust a code hosting platform
+serving them some repos, but might not fully trust other users
+managing or contributing to some of these repos. For example, the code
+hosting platform could have hooks in place to check that any object it
+receives doesn't contain malware or otherwise bad content. In this
+case it might be OK for the client to use a main remote and its LOP if
+they are both hosted by the code hosting platform, but not if the LOP
+is hosted elsewhere (where the content is not checked).
+
+In other contexts, a client should just not trust a server.
+
+So there should be different ways to configure how the client should
+behave when a server advertises a LOP to it at clone time.
+
+As the basic elements that a server can advertise about a LOP are a
+LOP name and a LOP URL, the client should base its decision about
+accepting a LOP on these elements.
+
+One simple way to be very strict in the LOP it accepts is for example
+for the client to check that the LOP is already configured on the
+client with the same name and URL as what the server advertises.
+
+In general default and "safe" settings should require that the LOP are
+configured on the client separately from the "promisor-remote"
+protocol and that the client accepts a LOP only when information about
+it from the protocol matches what has been already configured
+separately.
+
+What about LOP names?
+~~~~~~~~~~~~~~~~~~~~~
+
+In some contexts, for example if the clients sometimes fetch from each
+other, it can be a good idea for all the clients to use the same names
+for all the remotes they use, including LOPs.
+
+In other contexts, each client might want to be able to give the name
+it wants to each remote, including each LOP, it interacts with.
+
+So there should be different ways to configure how the client accepts
+or not the LOP name the server advertises.
+
+If a default or "safe" setting is used, then as such a setting should
+require that the LOP be configured separately, then the name would be
+configured separately and there is no risk that the server could
+dictate a name to a client.
+
+Could the main remote be bogged down by old or paranoid clients?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Yes, it could happen if there are too many clients that are either
+unwilling to trust the main remote or that just don't implement the
+"promisor-remote" protocol because they are too old or not fully
+compatible with the 'git' client.
+
+When serving such a client, the main remote has no other choice than
+to first fetch from its LOP, to then be able to provide to the client
+everything it requested. So the main remote, even if it has cleanup
+mechanisms (see section II.4 above), would be burdened at least
+temporarily with the large blobs it had to fetch from its LOP.
+
+Not behaving like this would be breaking backward compatibility, and
+could be seen as segregating clients. For example, it might be
+possible to implement a special mode that allows the server to just
+reject clients that don't implement the "promisor-remote" protocol or
+aren't willing to trust the main remote. This mode might be useful in
+a special context like a corporate environment. There is no plan to
+implement such a mode though, and this should be discussed separately
+later anyway.
+
+A better way to proceed is probably for the main remote to show a
+message telling clients that don't implement the protocol or are
+unwilling to accept the advertised LOP(s) that they would get faster
+clone and fetches by upgrading client software or properly setting
+them up to accept LOP(s).
+
+Waiting for clients to upgrade, monitoring these upgrades and limiting
+the use of LOPs to repos that are not very frequently accessed might
+be other good ways to make sure that some benefits are still reaped
+from LOPs. Over time, as more and more clients upgrade and benefit
+from LOPs, using them in more and more frequently accessed repos will
+become worth it.
+
+Corporate environments, where it might be easier to make sure that all
+the clients are up-to-date and properly configured, could hopefully
+benefit more and earlier from using LOPs.
+
+What about fetches?
+~~~~~~~~~~~~~~~~~~~
+
+There are different kinds of fetches. A regular fetch happens when
+some refs have been updated on the server and the client wants the ref
+updates and possibly the new objects added with them. A "backfill" or
+"lazy" fetch, on the contrary, happens when the client needs to use
+some objects it already knows about but doesn't have because they are
+on a promisor remote.
+
+Regular fetch
++++++++++++++
+
+In a regular fetch, the client will contact the main remote and a
+protocol negotiation will happen between them. It's a good thing that
+a protocol negotiation happens every time, as the configuration on the
+client or the main remote could have changed since the previous
+protocol negotiation. In this case, the new protocol negotiation
+should ensure that the new fetch will happen in a way that satisfies
+the new configuration of both the client and the server.
+
+In most cases though, the configurations on the client and the main
+remote will not have changed between 2 fetches or between the initial
+clone and a subsequent fetch. This means that the result of a new
+protocol negotiation will be the same as the previous result, so the
+new fetch will happen in the same way as the previous clone or fetch,
+using, or not using, the same LOP(s) as last time.
+
+"Backfill" or "lazy" fetch
+++++++++++++++++++++++++++
+
+When there is a backfill fetch, the client doesn't necessarily contact
+the main remote first. It will try to fetch from its promisor remotes
+in the order they appear in the config file, except that a remote
+configured using the `extensions.partialClone` config variable will be
+tried last. See
+link:partial-clone.html#using-many-promisor-remotes[the partial clone documentation].
+
+This is not new with this effort. In fact this is how multiple remotes
+have already been working for around 5 years.
+
+When using LOPs, having the main remote configured using
+`extensions.partialClone`, so it's tried last, makes sense, as missing
+objects should only be large blobs that are on LOPs.
+
+This means that a protocol negotiation will likely not happen as the
+missing objects will be fetched from the LOPs, and then there will be
+nothing left to fetch from the main remote.
+
+To secure that, it could be a good idea for LOPs to require a token
+from the client when it fetches from them. The client could get the
+token when performing a protocol negotiation with the main remote (see
+section II.6 above).
+
+V) Future improvements
+----------------------
+
+It is expected that at the beginning using LOPs will be mostly worth
+it either in a corporate context where the Git version that clients
+use can easily be controlled, or on repos that are infrequently
+accessed. (See the "Could the main remote be bogged down by old or
+paranoid clients?" section in the FAQ above.)
+
+Over time, as more and more clients upgrade to a version that
+implements the "promisor-remote" protocol v2 capability described
+above in section II.6), it will be worth it to use LOPs more widely.
+
+A lot of improvements may also help using LOPs more widely. Some of
+these improvements are part of the scope of this document like the
+following:
+
+  - Implementing a "remote-object-info" command in the
+    `git cat-file --batch` protocol and its variants to allow main
+    remotes to respond to requests about large blobs without fetching
+    them. (Eric Ju has started working on this based on previous work
+    by Calvin Wan.)
+
+  - Creating better cleanup and offload mechanisms for main remotes
+    and clients to prevent accumulation of large blobs.
+
+  - Developing more sophisticated protocol negotiation capabilities
+    between clients and servers for handling LOPs, for example adding
+    a filter-spec (e.g., blob:limit=<size>) or size limit for
+    filtering when cloning, or adding a token for LOP authentication.
+
+  - Improving security measures for LOP access, particularly around
+    token handling and authentication.
+
+  - Developing standardized ways to configure and manage multiple LOPs
+    across different environments. Especially in the case where
+    different LOPs serve the same content to clients in different
+    geographical locations, there is a need for replication or
+    synchronization between LOPs.
+
+Some improvements, including some that have been mentioned in the "0)
+Non Goals" section of this document, are out of the scope of this
+document:
+
+  - Implementing a new object representation for large blobs on the
+    client side.
+
+  - Developing pluggable ODBs or other object database backends that
+    could chunk large blobs, dedup the chunks and store them
+    efficiently.
+
+  - Optimizing data transfer between LOPs and clients/servers,
+    particularly for incompressible and non-deltifying content.
+
+  - Creating improved client side tools for managing large objects
+    more effectively, for example tools for migrating from Git LFS or
+    git-annex, or tools to find which objects could be offloaded and
+    how much disk space could be reclaimed by offloading them.
+
+Some improvements could be seen as part of the scope of this document,
+but might already have their own separate projects from the Git
+project, like:
+
+  - Improving existing remote helpers to access object storage or
+    developing new ones.
+
+  - Improving existing object storage solutions or developing new
+    ones.
+
+Even though all the above improvements may help, this document and the
+LOP effort should try to focus, at least first, on a relatively small
+number of improvements mostly those that are in its current scope.
+
+For example introducing pluggable ODBs and a new object database
+backend is likely a multi-year effort on its own that can happen
+separately in parallel. It has different technical requirements,
+touches other part of the Git code base and should have its own design
+document(s).
