Currently, in the git-log documentation, the reference to generating
patches does not match the section title. This can make the section
"Generating patch text with -p" hard to find, since typically readers of
the documentation will copy and paste to search the page.
Let's make this more convenient for readers by linking it directly to
the section.
Since git-log pulls in diff-generate-patch.txt, we can provide a direct
link to the section. Otherwise, change the verbiage to match exactly
what the section title is, to at least make searching for it an easier
task.

A GNU make pattern rule with multiple targets has always meant that
a single invocation of the recipe will build all the targets.
However in older versions of GNU make a recipe that did not really
build all the targets would be tolerated.
Starting with GNU make 4.4 this behavior is deprecated and pattern
rules are expected to generate files to match all the patterns.
If not all targets are created then GNU make will not consider any
target up to date and will re-run the recipe when it is run again.
Modify Documentation/Makefile to split the man page-creating pattern
rule into a separate pattern rule for each pattern.

"git receive-pack" used to use all the local refs as the boundary for
checking connectivity of the data "git push" sent, but now it uses
only the refs that it advertised to the pusher. In a repository with

Add a new `--exclude-hidden=` option that is similar to the one we just
added to git-rev-list(1). Given a section name `uploadpack` or `receive`

Users can optionally hide refs from remote users in git-upload-pack(1),
git-receive-pack(1) and others via the `transfer.hideRefs`, but there is
not an easy way to obtain the list of all visible or hidden refs right
now. We'll require just that though for a performance improvement in our
connectivity check.

the next pseudo-ref like `--all` or `--branches`.

Git learned pushing submodules without pushing the superproject by
the user specifying --recurse-submodules=only through 6c656c3fe4
("submodules: add RECURSE_SUBMODULES_ONLY value", 2016-12-20) and
225e8bf778 ("push: add option to push only submodules", 2016-12-20).
For users who use this feature regularly, it is desirable to have an
equivalent configuration.
It turns out that such a configuration (push.recurseSubmodules=only) is
already supported, even though it is neither documented nor mentioned
in the commit messages, due to the way the --recurse-submodules=only
feature was implemented (a function used to parse --recurse-submodules
was updated to support "only", but that same function is used to parse
push.recurseSubmodules too). What is left is to document it and test it,
which is what this commit does.
There is a possible point of confusion when recursing into a submodule
that itself has the push.recurseSubmodules=only configuration, because
if a repository has only its submodules pushed and not itself, its
superproject can never be pushed. Therefore, treat such configurations
as being "on-demand", and print a warning message.

Once upon a time, Matheus wrote some patches to make
git grep [--cached | <REVISION>] ...
restrict its output to the sparsity specification when working in a
sparse checkout[1]. That effort got derailed by two things:
(1) The --sparse-index work just beginning which we wanted to avoid
creating conflicts for
(2) Never deciding on flag and config names and planned high level
behavior for all commands.
More recently, Shaoxuan implemented a more limited form of Matheus'
patches that only affected --cached, using a different flag name,
but also changing the default behavior in line with what Matheus did.
This again highlighted the fact that we never decided on command line
flag names, config option names, and the big picture path forward.
The --sparse-index work has been mostly complete (or at least released
into production even if some small edges remain) for quite some time
now. We have also had several discussions on flag and config names,
though we never came to solid conclusions. Stolee once upon a time
suggested putting all these into some document in
Documentation/technical[3], which Victoria recently also requested[4].
I'm behind the times, but here's a patch attempting to finally do that.

In a similar spirit as the previous commit, the 'seen' branch gets

Rebuilding the 'jch' branch begins by reintegrating any topics between
'master' and 'jch', not 'master' and 'seen'.
In the maintainer guide, the documentation isn't quite right, since the
initial input to Meta/Reintegrate is "master..seen", not "master..jch".
This can lead to confusing results when generating the Meta/redo-jch.sh
script for the first time.
Additionally, rebuilding 'jch' takes place in two steps. First, running
the script up to the first "### match next" cut-line, and then comparing
the result with what's on 'next' (i.e. with "git diff jch next"). Then,
the remaining set of topics get merged down to 'jch' (which aren't on
'next') by running the entire "redo-jch.sh" script.
Clarify the documentation to reflect this.

things are usually run. Rather than answering questions individually,
extend Git's existing documentation about security vulnerabilities to

There are situations where the user might not want the default
setting where patch-id strips all whitespace. They might be working
in a language where white space is syntactically important, or they
might have CI testing that enforces strict whitespace linting. In
these cases, a whitespace change would result in the patch
fundamentally changing, and thus deserving of a different id.
Add a new mode that is exclusive of --stable and --unstable called
--verbatim. It also corresponds to the config
patchid.verbatim = true. In this mode, the stable algorithm is
used and whitespace is not stripped from the patch text.
Users of --unstable mainly care about compatibility with old git
versions, which unstripping the whitespace would break. Thus there
isn't a usecase for the combination of --verbatim and --unstable,
and we don't expose this so as to not add maintainence burden.

In addition to generating a shortlog based on committer, author, or the
identity in one or more specified trailers, it can be useful to generate
a shortlog based on an arbitrary commit format.
This can be used, for example, to generate a distribution of commit
activity over time, like so:
$ git shortlog --group='%cd' --date='format:%Y-%m' -s v2.37.0..
117 2022-06
274 2022-07
324 2022-08
263 2022-09
7 2022-10
Arbitrary commit formats can be used. In fact, `git shortlog`'s default
behavior (to count by commit authors) can be emulated as follows:
$ git shortlog --group='%aN <%aE>' ...
and future patches will make the default behavior (as well as
`--committer`, and `--group=trailer:<trailer>`) special cases of the
more flexible `--group` option.
Note also that the SHORTLOG_GROUP_FORMAT enum value is used only to
designate that `--group:<format>` is in use when in stdin mode to
declare that the combination is invalid.

Prepare for a future patch which will introduce arbitrary pretty formats
via the `--group` argument.
To allow additional customizability (for example, to support something
like `git shortlog -s --group='%aD' --date='format:%Y-%m' ...` (which
groups commits by the datestring 'YYYY-mm' according to author date), we
must store off the `--date` parsed from calling `parse_revision_opt()`.
Note that this also affects custom output `--format` strings in `git
shortlog`. Though this is a behavior change, this is arguably fixing a
long-standing bug (ie., that `--format` strings are not affected by
`--date` specifiers as they should be).

When pruning objects with `--cruft`, `git repack` offers some
flexibility when selecting the set of which objects are pruned via the
`--cruft-expiration` option.
This is useful for expiring objects which are older than the grace
period, making races where to-be-pruned objects become reachable and
then ancestors of freshly pushed objects, leaving the repository in a
corrupt state after pruning substantially less likely [1].
But in practice, such races are impossible to avoid entirely, no matter
how long the grace period is. To prevent this race, it is often
advisable to temporarily put a repository into a read-only state. But in
practice, this is not always practical, and so some middle ground would
be nice.
This patch introduces a new option, `--expire-to`, which teaches `git
repack` to write an additional cruft pack containing just the objects
which were pruned from the repository. The caller can specify a
directory outside of the current repository as the destination for this
second cruft pack.
This makes it possible to prune objects from a repository, while still
holding onto a supplemental copy of them outside of the original
repository. Having this copy on-disk makes it substantially easier to
recover objects when the aforementioned race is encountered.
`--expire-to` is implemented in a somewhat convoluted manner, which is
to take advantage of the fact that the first time `write_cruft_pack()`
is called, it adds the name of the cruft pack to the `names` string
list. That means the second time we call `write_cruft_pack()`, objects
in the previously-written cruft pack will be excluded.
As long as the caller ensures that no objects are expired during the
second pass, this is sufficient to generate a cruft pack containing all
objects which don't appear in any of the new packs written by `git
repack`, including the cruft pack. In other words, all of the objects
which are about to be pruned from the repository.
It is important to note that the destination in `--expire-to` does not
necessarily need to be a Git repository (though it can be) Notably, the
expired packs do not contain all ancestors of expired objects. So if the
source repository contains something like:
<unreachable>
/
C1 --- C2
\
refs/heads/master
where C2 is unreachable, but has a parent (C1) which is reachable, and
C2 would be pruned, then the expiry pack will contain only C2, not C1.

Add global counters mechanism to Trace2.
The Trace2 counters mechanism adds the ability to create a set of
global counter variables and an API to increment them efficiently.
Counters can optionally report per-thread usage in addition to the sum
across all threads.
Counter events are emitted to the Trace2 logs when a thread exits and
at process exit.
Counters are an alternative to `data` and `data_json` events.
Counters are useful when you want to measure something across the life
of the process, when you don't want per-measurement events for
performance reasons, when the data does not fit conveniently within a
region, or when your control flow does not easily let you write the
final total. For example, you might use this to report the number of
calls to unzip() or the number of de-delta steps during a checkout.

Add stopwatch timer mechanism to Trace2.
Timers are an alternative to Trace2 Regions. Regions are useful for
measuring the time spent in various computation phases, such as the
time to read the index, time to scan for unstaged files, time to scan
for untracked files, and etc.
However, regions are not appropriate in all places. For example,
during a checkout, it would be very inefficient to use regions to
measure the total time spent inflating objects from the ODB from
across the entire lifetime of the process; a per-unzip() region would
flood the output and significantly slow the command; and some form of
post-processing would be requried to compute the time spent in unzip().
Timers can be used to measure a series of timer intervals and emit
a single summary event (at thread and/or process exit).

Add an option, --stdin, to merge-tree which will accept lines of input
with two branches to merge per line, and which will perform all the
merges and give output for each in turn. This option implies -z, and
modifies the output to also include a merge status since the exit code
of the program can no longer convey that information now that multiple
merges are involved.
This could be useful, for example, by Git hosting providers. When one
branch is updated, one may want to check whether all code reviews
targetting that branch can still cleanly merge. Avoiding the overhead
of starting up a separate process for each of those code reviews might
provide significant savings in a repository with many code reviews.

To make sure that our manpages are rebuilt when any of the included
source files change and only the affected manpages are rebuilt,
'build-docdep.perl' scans our documentation source files for include
directives, and outputs 'make' dependencies to be included by
'Documentation/Makefile'. This script relies on Perl's hash data
structures, and generates its output while iterating over them, and
since hashes in Perl are very much unordered, the output varies
greatly from run to run, both the order of targets and the order of
dependencies of each target.
This lack of ordering doesn't matter for 'make', because it cares
neither about the order of targets in a Makefile nor about the order
of a target's dependencies. However, it does matter to developers
looking into build issues potentially involving these generated
dependencies, as it's rather hard to tell whether there are any
relevant (i.e. not order-only) changes among the dependencies compared
to the previous run.
So let's make 'build-docdep.perl's output stable and ordered by
sorting the keys of the hashes before iterating over them.

There will be two primary ways to advertise a bundle list: as a list of
packet lines in Git's protocol v2 and as a config file served from a
bundle URI. Both of these fundamentally use a list of key-value pairs.
We will use the same set of key-value pairs across these formats.
Create a new bundle_list_update() method that is currently unusued, but
will be used in the next change. It inspects each key to see if it is
understood and then applies it to the given bundle_list. Here are the
keys that we teach Git to understand:
* bundle.version: This value should be an integer. Git currently
understands only version 1 and will ignore the list if the version is
any other value. This version can be increased in the future if we
need to add new keys that Git should not ignore. We can add new
"heuristic" keys without incrementing the version.
* bundle.mode: This value should be one of "all" or "any". If this
mode is not understood, then Git will ignore the list. This mode
indicates whether Git needs all of the bundle list items to make a
complete view of the content or if any single item is sufficient.
The rest of the keys use a bundle identifier "<id>" as part of the key
name. Keys using the same "<id>" describe a single bundle list item.
* bundle.<id>.uri: This stores the URI of the bundle item. This
currently is expected to be an absolute URI, but will be relaxed to be
a relative URI in the future.
While parsing, return an error if a URI key is repeated, since we can
make that restriction with bundle lists.
Make the git_parse_int() method global so we can parse the integer
version value carefully.

The C99 section of the CodingGuidelines is a good overview of what we

Per [1] we couldn't use it for the longest time due to MSVC not
supporting it, but nowadays by requiring C99 we rely on the MSVC
version that does, but we can't use it yet because a C library that
MinGW uses doesn't support it.

The first use of variables in initializer elements appears to have
been 2b6854c863a (Cleanup variables in cat-file, 2007-04-21) released
with v1.5.2.
Some of those caused portability issues, and e.g. that "cat-file" use
was changed in 66dbfd55e38 (Rewrite dynamic structure initializations
to runtime assignment, 2010-05-14) which went out with v1.7.2.
But curiously 66dbfd55e38 missed some of them, e.g. an archive.c use
added in d5f53d6d6f2 (archive: complain about path specs that don't
match anything, 2009-12-12), and another one in merge-index.c (later
builtin/merge-index.c) in 0077138cd9d (Simplify some instances of
run_command() by using run_command_v_opt()., 2009-06-08).
As far as I can tell there's been no point since 2b6854c863a in 2007
where a compiler that didn't support this has been able to compile
git. Presumably 66dbfd55e38 was an attempt to make headway with wider
portability that ultimately wasn't completed.
In any case, we are thoroughly reliant on this syntax at this point,
so let's update the guidelines, see
https://lore.kernel.org/git/xmqqy1tunjgp.fsf@gitster.g/ for the
initial discussion.

Since 7bc341e21b5 (git-compat-util: add a test balloon for C99
support, 2021-12-01) we've had a hard dependency on C99, but the prose
in CodingGuidelines was written under the assumption that we were
using C89 with a few C99 features.
As the updated prose notes we'd still like to hold off on novel C99
features, but let's make it clear that we target that C version, and
then enumerate new C99 features that are safe to use.

Suppose you are managing many maintenance tracks in your project,
and some of the more recent ones are maint-2.36 and maint-2.37.
Further imagine that your project recently tagged the official 2.38
release, which means you would need to start maint-2.38 track soon,
by doing:
$ git checkout -b maint-2.38 v2.38.0^0
$ git branch --list 'maint-2.3[6-9]'
* maint-2.38
maint-2.36
maint-2.37
So far, so good. But it also is reasonable to want not to have to
worry about which maintenance track is the latest, by pointing a
more generic-sounding 'maint' branch at it, by doing:
$ git symbolic-ref refs/heads/maint refs/heads/maint-2.38
which would allow you to say "whichever it is, check out the latest
maintenance track", by doing:
$ git checkout maint
$ git branch --show-current
maint-2.38
It is arguably better to say that we are on 'maint-2.38' rather than
on 'maint', and "git merge/pull" would record "into maint-2.38" and
not "into maint", so I think what we have is a good behaviour.
One thing that is slightly irritating, however, is that I do not
think there is a good way (other than "cat .git/HEAD") to learn that
you checked out 'maint' to get into that state. Just like the output
of "git branch --show-current" shows above, "git symbolic-ref HEAD"
would report 'refs/heads/maint-2.38', bypassing the intermediate
symbolic ref at 'refs/heads/maint' that is pointed at by HEAD.
The internal resolve_ref() API already has the necessary support for
stopping after resolving a single level of a symbolic-ref, and we
can expose it by adding a "--[no-]recurse" option to the command.

Two documentation issues exist in the technical docs for the bundle URI
feature.
First, there is an extraneous "the" across a linebreak, making the
nonsensical phrase "the bundle the list" which should just be "the
bundle list".
Secondly, the asciidoc update treats the string "`have`s" as starting a
"<code>" block, but the second tick is interpreted as an apostrophe
instead of a closing "</code>" tag. This causes entire sentences to be
formatted as code until the next one comes along. Simply adding a space
here does not work properly as the rendered HTML keeps that space.
Instead, restructure the sentence slightly to avoid using a plural,
allowing the HTML to render correctly.

revision.c::handle_revision_arg_1() resolves <rev>^! by first adding the
negated parents and then <rev> itself. builtin_diff_combined() expects
the first tree to be the merge and the remaining ones to be the parents,
though. This mismatch results in bogus diff output.
Remember the first tree that doesn't belong to a parent and use it
instead of blindly picking the first one. This makes "git diff <rev>^!"
consistent with "git show <rev>^!".

An earlier patch discussed and fixed a scenario where Git could be used
as a vector to exfiltrate sensitive data through a Docker container when
a potential victim clones a suspicious repository with local submodules
that contain symlinks.
That security hole has since been plugged, but a similar one still
exists. Instead of convincing a would-be victim to clone an embedded
submodule via the "file" protocol, an attacker could convince an
individual to clone a repository that has a submodule pointing to a
valid path on the victim's filesystem.
For example, if an individual (with username "foo") has their home
directory ("/home/foo") stored as a Git repository, then an attacker
could exfiltrate data by convincing a victim to clone a malicious
repository containing a submodule pointing at "/home/foo/.git" with
`--recurse-submodules`. Doing so would expose any sensitive contents in
stored in "/home/foo" tracked in Git.
For systems (such as Docker) that consider everything outside of the
immediate top-level working directory containing a Dockerfile as
inaccessible to the container (with the exception of volume mounts, and
so on), this is a violation of trust by exposing unexpected contents in
the working copy.
To mitigate the likelihood of this kind of attack, adjust the "file://"
protocol's default policy to be "user" to prevent commands that execute
without user input (including recursive submodule initialization) from
taking place by default.

The 'git maintenance unregister' subcommand has a step that removes the
current repository from the multi-valued maitenance.repo config key.
This fails if the repository is not listed in that key. This makes
running 'git maintenance unregister' twice result in a failure in the
second instance.
This failure exit code is helpful, but its message is not. Add a new
die() message that explicitly calls out the failure due to the
repository not being registered.
In some cases, users may want to run 'git maintenance unregister' just
to make sure that background jobs will not start on this repository, but
they do not want to check to see if it is registered first. Add a new
'--force' option that will siltently succeed if the repository is not
already registered.
Also add an extra test of 'git maintenance unregister' at a point where
there are no registered repositories. This should fail without --force.

We attribute each documentation text file to a man section by finding a
line in the file that looks like "gitfoo(<digit>)". Commit cc75e556a9
("scalar: add to 'git help -a' command list", 2022-09-02) updated this
logic to look not only for "gitfoo" but also "scalarfoo". In doing so,
it forgot to account for the fact that after the updated regex has found
a match, the man section is no longer to be found in `$1` but now lives
in `$2`.
This makes our git(1) manpage look as follows:
Main porcelain commands
git-add(git)
Add file contents to the index.
[...]
gitk(git)
The Git repository browser.
scalar(scalar)
A tool for managing large Git repositories.
Restore the man sections by not capturing the (git|scalar) part of the
match into `$1`.
As noted by Ævar [1], we could even match any "foo" rather than just
"gitfoo" and "scalarfoo", but that's a larger change. For now, just fix
the regression in cc75e556a9.

The `expire` sub-command unlinks any packs that are (a) contained in the
MIDX, but (b) have no objects referenced by the MIDX.
This sub-command ignores `.keep` packs, which remain on-disk even if
they have no objects referenced by the MIDX. Cruft packs, however,
aren't given the same treatment: if none of the objects contained in the
cruft pack are selected from the cruft pack by the MIDX, then the cruft
pack is eligible to be expired.
This is less than desireable, since the cruft pack has important
metadata about the individual object mtimes, which is useful to
determine how quickly an object should age out of the repository when
pruning.
Ordinarily, we wouldn't expect the contents of a cruft pack to
duplicated across non-cruft packs (and we'd expect to see the MIDX
select all cruft objects from other sources even less often). But
nonetheless, it is still possible to trick the `expire` sub-command into
removing the `.mtimes` file in this circumstance.
Teach the `expire` sub-command to ignore cruft packs in the same manner
as it does `.keep` packs, in order to keep their metadata around, even
when they are unreferenced by the MIDX.
