Julia Evans 042d6f3402 doc: git-checkout: clarify `-b` and `-B`
From user feedback: several users reported having trouble understanding
the difference between `-b` and `-B` ("I think it's because my brain
expects it to contrast with `-b`, but instead it starts off explaining
how they're the same").

Also, in `-B`, 2 users can't tell what the branch is reset *to*.

Simplify the sentence structure in the explanations of `-b` and `-B` and
add a little extra information (what `<start-point>` is, what the branch
is reset to).

Splitting up `-b` and `-B` into separate items helps simplify the
sentence structure since there's less "In this case...".

Replace the long "the branch is not reset/created unless "git checkout"
is successful..." with just "will fail", since we should generally
assume that Git will fail operations in a clean way and not leave
operations half-finished, and that cases where it does not fail cleanly
are the exceptions that the documentation should flag.

Julia Evans ab215e4a8d doc: git-checkout: clarify `git checkout <branch>`
From user feedback: several users commented that "Local modifications
to the files in the working tree are kept, so that they can be committed
to the <branch>." didn't seem accurate to them, since
`git checkout <branch>` will often fail.

One user also thought that "... and by pointing HEAD at the branch"
was something that _they_ had to do somehow ("How do I point HEAD at
a branch?") rather than a description of what the `git checkout`
operation is doing for them.

Explain when `git checkout <branch>` will fail and clarify that
"pointing HEAD at the branch" is part of what the command does.

6 users commented that the "You could omit <branch>..." section is
extremely confusing. Explain this in a much more direct way.

Julia Evans ea03d5ae5c doc: git-checkout: clarify ARGUMENT DISAMBIGUATION
There's no need to use the terms "pathspec" or "tree-ish" in the
ARGUMENT DISAMBIGUATION section, which are terms that (from user
feedback on this page) many users do not understand.

"tree-ish" is actually not accurate here: `git checkout` in this case
takes a commit-ish, not a tree-ish. So we can say "branch or commit"
instead of "tree-ish" which is both more accurate and uses more familiar
terms.

And now that the intro to the man pages mentions that `git checkout` has
"two main modes", it makes sense to refer to this disambiguation section
to understand how Git decides which one to use when there's an overlap
in syntax.

Julia Evans 21a5f9442e doc: git-checkout: clarify intro sentence
From user feedback: in the first paragraph, 5 users reported not
understanding the terms "pathspec" and 1 user reported not understanding
the term "HEAD". Of the users who said they didn't know what "pathspec"
means, 3 said they couldn't understand what the paragraph was trying to
communicate as a result.

One user also commented that "If no pathspec was given..." makes
`git checkout <branch>` sounds like a special edge case, instead of
being one of the most common ways to use this core Git command.

It looks like the goal of this paragraph is to communicate that `git
checkout` has two different modes: one where you switch branches and one
where you just update your working directory files/index. So say that
directly, and use more familiar language (including examples) to say it.

Phillip Wood 67d9b39cc7 breaking-changes: switch default branch to main
Since 1296cbe4b4 (init: document `init.defaultBranch` better,
2020-12-11) "git-init.adoc" has advertised that the default name
of the initial branch may change in the future. The name "main"
is chosen to match the default used by the big Git forge web sites.

The advice printed when init.defaultBranch is not set is updated
to say that the default will change to "main" in Git 3.0. Building
with WITH_BREAKING_CHANGES enabled removes the advice and changes
the default branch name to "main". The code in guess_remote_head()
that looks for "refs/heads/master" is left unchanged as that is only
called when the remote server does not support the symref capability
in the v0 protocol or the symref extension to the ls-refs list in the
v2 protocol. Such an old server is more likely to be using "master"
as the default branch name.

With the exception of the "git-init.adoc" the documentation is left
unchanged. I had hoped to parameterize the name of the default branch
by using an asciidoc attribute. Unfortunately attribute expansion
is inhibited by backticks and we use backticks to mark up ref names
so that idea does not work. As the changes to git-init.adoc show
inserting ifdef's around each instance of the branch name "master"
is cumbersome and makes the documentation sources harder to read.

Apart from "git-init.adoc" there are some other files where "master" is
used as the name of the initial branch rather than as an example of a
branch name such as "user-manual.adoc" and "gitcore-tutorial.adoc". The
name appears a lot in those so updating it with ifdef's is not really
practical. We can update that document in the 3.0 release cycle. The
other documentation where master is used as an example branch name
can be gradually converted over time.

Christian Couder c213820c51 promisor-remote: allow a client to check fields
A previous commit allowed a server to pass additional fields through
the "promisor-remote" protocol capability after the "name" and "url"
fields, specifically the "partialCloneFilter" and "token" fields.

Let's make it possible for a client to check if these fields match
what it expects before accepting a promisor remote.

We allow this by introducing a new "promisor.checkFields"
configuration variable. It should contain a comma or space separated
list of fields that will be checked.

By limiting the protocol to specific well-defined fields, we ensure
both server and client have a shared understanding of field
semantics and usage.

Christian Couder 4bf7ae3123 promisor-remote: allow a server to advertise more fields
For now the "promisor-remote" protocol capability can only pass "name"
and "url" information from a server to a client in the form
"name=<remote_name>,url=<remote_url>".

To allow clients to make more informed decisions about which promisor
remotes they accept, let's make it possible to pass more information
by introducing a new "promisor.sendFields" configuration variable.

On the server side, information about a remote `foo` is stored in
configuration variables named `remote.foo.<variable-name>`. To make
it clearer and simpler, we use `field` and `field name` like this:

  * `field name` refers to the <variable-name> part of such a
    configuration variable, and

  * `field` refers to both the `field name` and the value of such a
    configuration variable.

The "promisor.sendFields" configuration variable should contain a
comma or space separated list of field names that will be looked up
in the configuration of the remote on the server to find the values
that will be passed to the client.

Only a set of predefined field names are allowed. The only field
names in this set are "partialCloneFilter" and "token". The
"partialCloneFilter" field name specifies the filter definition used
by the promisor remote, and the "token" field name can provide an
authentication credential for accessing it.

For example, if "promisor.sendFields" is set to "partialCloneFilter",
and the server has the "remote.foo.partialCloneFilter" config
variable set to a value, then that value will be passed in the
"partialCloneFilter" field in the form "partialCloneFilter=<value>"
after the "name" and "url" fields.

A following commit will allow the client to use the information to
decide if it accepts the remote or not. For now the client doesn't do
anything with the additional information it receives.

Meet Soni 0f0a8a11c0 builtin/refs: add 'exists' subcommand
As part of the ongoing effort to consolidate reference handling,
introduce a new `exists` subcommand. This command provides the same
functionality and exit-code behavior as `git show-ref --exists`, serving
as its modern replacement.

The logic for `show-ref --exists` is minimal. Rather than creating a
shared helper function which would be overkill for ~20 lines of code,
its implementation is intentionally duplicated here. This contrasts with
`git refs list`, where sharing the larger implementation of
`for-each-ref` was necessary.

Documentation for the new subcommand is also added to the `git-refs(1)`
man page.

Karthik Nayak 929b1d08f7 Documentation: note styling for bit fields
Our codebase uses a lot of bit field variables, generally to mark
boolean type variables. While there is a formatting rule in the
'.clang-format', there is no guideline specified in the
'CodingGuidelines'.

Since the '.clang-format' is not yet enforced, let's also add a
guideline with the same rule as mentioned in the '.clang-format', which
is to not use any spaces around the colon, like so:

    unsigned my_field:1;
    unsigned other_field:1;
    unsigned field_with_longer_name:1;

This would allow us not to modify the clang-format file, and more
importantly, discourage people from doing ugly alignment with spaces,
i.e.

    unsigned my_field               : 1;
    unsigned            other_field : 1;
    unsigned field_with_longer_name : 1;

Phillip Wood fdae4114a6 breaking-changes: deprecate support for core.commentString=auto
When "core.commentString" is set to "auto" then "git commit" will
automatically select the comment character ensuring that it is not the
first character on any of the lines in the commit message. This was
introduced by commit 84c9dc2c5a (commit: allow core.commentChar=auto
for character auto selection, 2014-05-17). The motivation seems to be
to avoid commenting out lines from the existing message when amending
a commit that was created with a message from a file.

Unfortunately this feature does not work with:

 * commit message templates that contain comments.

 * prepare-commit-msg hooks that introduce comments.

 * "git commit --cleanup=strip --edit -F <file>" which means that it
   is incompatible with

   - the "fixup" and "squash" commands of "git rebase -i" as the
     comments added by those commands are then treated as part of
     the commit message.

   - the conflict comments added to the commit message by "git
     cherry-pick", "git rebase" etc. as these comments are then
     treated as part of the commit message.

It is also ignored by "git notes" when amending a note.

The issues with comments coming from a template, hook or file are a
consequence of the design of this feature and are therefore hard to
fix.

As the costs of this feature outweigh the benefits, deprecate it and
remove it in Git 3.0. If someone comes up with some patches that fix
all the issues in a maintainable way then I'd be happy to see this
change reverted.

The next commits will add a warning and some advice for users on how
they can update their config settings.

brian m. carlson 716d905792 docs: note that extensions.compatobjectformat is incomplete
The compatibility object format is only implemented for loose objects,
not packed objects, so anyone attempting to push or fetch data into a
repository with this option will likely not see it work as expected.  In
addition, the underlying storage of loose object mapping is likely to
change because the current format is inefficient and does not handle
important mapping information such as that of submodules.

It would have been preferable to initially document that this was not
yet ready for prime time, but we did not do so.  We hinted at the fact
that this functionality is incomplete in the description, but did not
say so explicitly.  Let's do so now: indicate that this feature is
incomplete and subject to change and that the option is not designed to
be used by end users.

Johannes Sixt 457534d041 progress: pay attention to (customized) delay time
Using one of the start_delayed_*() functions, clients of the progress
API can request that a progress meter is only shown after some time.
To do that, the implementation intends to count down the number of
seconds stored in struct progress by observing flag progress_update,
which the timer interrupt handler sets when a second has elapsed. This
works during the first second of the delay. But the code forgets to
reset the flag to zero, so that subsequent calls of display_progress()
think that another second has elapsed and decrease the count again
until zero is reached. Due to the frequency of the calls, this happens
without an observable delay in practice, so that the effective delay is
always just one second.

This bug has been with us since the inception of the feature. Despite
having been touched on various occasions, such as 8aade107dd
(progress: simplify "delayed" progress API), 9c5951cacf (progress:
drop delay-threshold code), and 44a4693bfc (progress: create
GIT_PROGRESS_DELAY), the short delay went unnoticed.

Copy the flag state into a local variable and reset the global flag
right away so that we can detect the next clock tick correctly.

Since we have not had any complaints that the delay of one second is
too short nor that GIT_PROGRESS_DELAY is ignored, people seem to be
comfortable with the status quo. Therefore, set the default to 1 to
keep the current behavior.

Jean-Noël Avila f38786baa7 doc: fix asciidoc format compatibility in pretty-formats.adoc
Asciidoc.py and Asciidoctor do not process the '+' verbatim the same way. A
span is detected when the format sign (here '+')is preceded by a non-word
character. It seems that '{nbsp}' is considered a non-word sign by
Asciidoc.py, but not by Asciidoctor.

Using a double format-sign opens 'unconstrained' span, independent on the
preceding character in both engines.

The '+' sign is used instead of the backtick '`' because it is not processed
as synopsis in asciidoc.py. Unfortunately, the post-processing of verbatim
synopsis in asciidoctor cannot be bypassed and formatting of the parentheses
is forced in syntax sign instead of keywords, unless a proper grammar
analyzer is used.

- Mention early on that "index" is another word for "staging area",

  (`git status`) uses the term "staged", and many Git users are
  unfamiliar with the term "index"
- Remove "It typically adds" (it's not clear what "typically" means),
  and instead mention that `git add -p` can be used to add
  partial contents
- Currently the introduction is somewhat repetitive ("to prepare the

  as the contents of the next commit."), replace with a single sentence
  ("The "index" [...] is where Git stores the contents of the next

Lucas Seiki Oshiro a81224d128 repo: add the --format flag
Add the --format flag to git-repo-info. By using this flag, the users
can choose the format for obtaining the data they requested.

Given that this command can be used for generating input for other
applications and for being read by end users, it requires at least two
formats: one for being read by humans and other for being read by
machines. Some other Git commands also have two output formats, notably
git-config which was the inspiration for the two formats that were
chosen here:

- keyvalue, where the retrieved data is printed one per line, using =
  for delimiting the key and the value. This is the default format,
  targeted for end users.
- nul, where the retrieved data is separated by NUL characters, using
  the newline character for delimiting the key and the value. This
  format is targeted for being read by machines.

Currently, `git rev-parse` covers a wide range of functionality not
directly related to parsing revisions, as its name suggests. Over time,
many features like parsing datestrings, options, paths, and others
were added to it because there wasn't a more appropriate command
to place them.

Create a new Git command called `repo`. `git repo` will be the main
command for obtaining the information about a repository (such as
metadata and metrics).

Also declare a subcommand for `repo` called `info`. `git repo info`
will bring the functionality of retrieving repository-related
information currently returned by `rev-parse`.

Add the required documentation and build changes to enable usage of
this subcommand.

Aditya Garg f33b2207da send-email: enable copying emails to an IMAP folder without actually sending them
`git imap-send` was built on the idea of copying emails to an IMAP folder
like drafts, and sending them later using an email client. Currently
the only way to do it is by piping output of `git format-patch` to IMAP
send.

Add another way to do it by using `git send-email` with the
`--use-imap-only` or `sendmail.useImapOnly` option. This allows users to
use the advanced features of `git send-email` like tweaking Cc: list
programmatically, compose the cover letter, etc. and then send the well
formatted emails to an IMAP folder using `git imap-send`.

While at it, use `` instead of '' for --smtp-encryption ssl in help

Aditya Garg 04133f5bc4 send-email: add ability to send a copy of sent emails to an IMAP folder
Some email providers like Apple iCloud Mail do not support sending a copy
of sent emails to the "Sent" folder if SMTP server is used. As a
workaround, various email clients like Thunderbird which rely on SMTP,
use IMAP to send a copy of sent emails to the "Sent" folder. Something
similar can be done if sending emails via `git send-email`, by using
the `git imap-send` command to send a copy of the sent email to an IMAP
folder specified by the user.

Add this functionality to `git send-email` by introducing a new
configuration variable `sendemail.imapfolder` and command line option
`--imap-folder` which specifies the IMAP folder to send a copy of the
sent emails to. If specified, a copy of the sent emails will be sent
by piping the emails to `git imap-send` command, after all emails are
sent via SMTP and the SMTP server has been closed.

The synopsis section has an extra closing bracket, like this:

The "--also-filter-submodules" option was added by f05da2b4 (clone,

Because it makes sense only when used with the "--filter=<filter>"

For simplifying automated translation of the documentation, it is better to
only present one term in each entry of a description list of options. This
is because most of these terms can automatically be marked as
notranslatable.

Also, due to portability issues, the script generate-configlist.sh can no
longer insert newlines in the output. However, the result is that it no
longer correctly handles multiple terms in a single entry of definition
lists.

As a result, we now check that these entries do not exist in the

Jean-Noël Avila 63d33eb7f6 doc: check well-formedness of delimited sections
Having an empty line before each delimited sections is not required by
asciidoc, but it is a safety measure that prevents generating malformed
asciidoc when generating translated documentation.

When a delimited section appears just after a paragraph, the asciidoc
processor checks that the length of the delimited section header is
different from the length of the paragraph. If it is not, the asciidoc
processor will generate a title. In the original English documentation, this
is not a problem because the authors always check the output of the asciidoc
processor and fix the length of the delimited section header if it turns out
to be the same as the paragraph length. However, this is not the case for
translations, where the authors have no way to check the length of the
delimited section header or the output of the asciidoc processor. This can
lead to a section title that is not intended.

Indeed, this test also checks that titles are correctly formed, that is,
the length of the underline is equal to the length of the title (otherwise
it would not be a title but a section header).

Finally, this test checks that the delimited section are terminated within
the same file.

Jeff King a1dfa5448d diff: teach tree-diff a max-depth parameter
When you are doing a tree-diff, there are basically two options: do not
recurse into subtrees at all, or recurse indefinitely. While most
callers would want to always recurse and see full pathnames, some may
want the efficiency of looking only at a particular level of the tree.
This is currently easy to do for the top-level (just turn off
recursion), but you cannot say "show me what changed in subdir/, but do
not recurse".

This patch adds a max-depth parameter which is measured from the closest
pathspec match, so that you can do:

  git log --raw --max-depth=1 -- a/b/c

and see the raw output for a/b/c/, but not those of a/b/c/d/
(instead of the raw output you would see for a/b/c/d).

Patrick Steinhardt 7aa619c36f builtin/reflog: implement subcommand to write new entries
While we provide a couple of subcommands in git-reflog(1) to remove
reflog entries, we don't provide any to write new entries. Obviously
this is not an operation that really would be needed for many use cases
out there, or otherwise people would have complained that such a command
does not exist yet. But the introduction of the "reftable" backend
changes the picture a bit, as it is now basically impossible to manually
append a reflog entry if one wanted to do so due to the binary format.

Plug this gap by introducing a simple "write" subcommand. For now, all
this command does is to append a single new reflog entry with the given
object IDs and message to the reflog. More specifically, it is not yet
possible to:

  - Write multiple reflog entries at once.

  - Insert reflog entries at arbitrary indices.

  - Specify the date of the reflog entry.

  - Insert reflog entries that refer to nonexistent objects.

If required, those features can be added at a future point in time. For
now though, the new command aims to fulfill the most basic use cases
while being as strict as possible when it comes to verifying parameters.

Patrick Steinhardt 649c7bb77a builtin/reflog: improve grouping of subcommands
The way subcommands of git-reflog(1) are laid out does not make any
immediate sense. Reorder them such that read-only subcommands precede
writing commands for a bit more structure.

Furthermore, move the "expire" subcommand last. This prepares for a
subsequent change where we are about to introduce a new "write" command
to append reflog entries. Like this, the writing subcommands are ordered
such that those affecting a single reflog come before those spanning
across all reflogs.

With 974cdca345 (doc: introduce a synopsis typesetting, 2024-09-24) we

Meet Soni eecccfe98b builtin/refs: add list subcommand
Git's reference management is distributed across multiple commands. As
part of an ongoing effort to consolidate and modernize reference
handling, introduce a `list` subcommand under the `git refs` umbrella as
a replacement for `git for-each-ref`.

Implement `cmd_refs_list` by having it call the `for_each_ref_core()`
helper function. This helper was factored out of the original
`cmd_for_each_ref` in a preceding commit, allowing both commands to
share the same core logic as independent peers.

Add documentation for the new command. The man page leverages the shared
options file, created in a previous commit, by using the AsciiDoc
`include::` macro to ensure consistency with git-for-each-ref(1).

the common options from the `git-for-each-ref` man page into a
shareable file `for-each-ref-options.adoc` and update

This change is a pure refactoring and results in no change to the

Johannes Schindelin ce6ccbaf92 mingw: drop Windows 7-specific work-around
In ac33519ddf (mingw: restrict file handle inheritance only on Windows
7 and later, 2019-11-22), I introduced code to safe-guard the
defense-in-depth handling that restricts handles' inheritance so that it
would work with Windows 7, too.

Let's revert this patch: Git for Windows dropped supporting Windows 7 (and
Windows 8) directly after Git for Windows v2.46.2. For full details, see
https://gitforwindows.org/requirements#windows-version.

Actually, on second thought: revert only the part that makes this handle
inheritance restriction logic optional and that suggests to open a bug
report if it fails, but keep the fall-back to try again without said
logic: There have been a few false positives over the past few years
(where the warning was triggered e.g. because Defender was still
accessing a file that Git wanted to overwrite), and the fall-back logic
seems to have helped occasionally in such situations.

This patch compliments the previous commit, where builtins that use
add-patch infrastructure now respect diff.context and
diff.interHunkContext file configurations.

In particular, this patch helps users who don't want to set persistent
context configurations or just want a way to override them on a one-time
basis, by allowing the relevant builtins to accept corresponding command
line options that override the file configurations.

This mimics commands such as diff and log, which allow for both context
file configuration and command line overrides.

K Jayatheerth 1fa06ceddf submodule: prevent overwriting .gitmodules on path reuse
Adding a submodule at a path that previously hosted
another submodule (e.g., 'child') reuses the submodule
name derived from the path. If the original submodule
was only moved (e.g., to 'child_old') and not renamed,
this silently overwrites its configuration in .gitmodules.

This behavior loses user configuration and causes
confusion when the original submodule is expected
to remain intact. It assumes that the path-derived
name is always safe to reuse, even though the name
might still be in use elsewhere in the repository.

Teach module_add() to check if the computed submodule
name already exists in the repository's submodule config,
and if so, refuse the operation unless the user explicitly
renames the submodule or uses the --force option,
which will automatically generate a unique name by
appending a number (e.g., child1).

Junio C Hamano 9b2527caa4 CodingGuidelines: document test balloons in flight
Due to portability concerns, we do not blindly say "It is in [[this
standard]], so we will make liberal use of it" for many features,
and use of C99 language features follow this same principle.  When
we contemplate adopting a language feature that we haven't used in
our codebase, we typically first raise a test balloon, which

 - is a piece of code that exercises the language feature we are
   trying to see if it is OK to adopt

 - is in a small section of code that we know everybody who cares
   about having a working Git must be compiling

 - is in a fairly stable part of the code, to allow reverting it
   easily if some platforms do not understand it yet.

After a few years, with no breakage report from the community, we'd
declare that the feature is now safe to use in our codebase.  Before
that, we forbid the use of the language construct except for the
designated test balloon code site.

The CodingGuidelines document lists these selected features that we
already have determined that they are safe, and also those features
that we know some platforms had trouble with.

Let's also start listing ongoing test balloons and expected timeline
for adoption.  Recently phillip proposed to adopt the syntax to
spell a structure literally (i.e. compound literal) with a new test
balloon, which Patrick made redundant by pointing out an existing
one we had already.but without documenting it.  Start the new section
with an entry for that test balloon.

In 036876a106 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.

Follow through with that intent and remove `git_config()`. All callsites
are adjusted so that they use `repo_config(the_repository, ...)`
instead. While some callsites might already have a repository available,
this mechanical conversion is the exact same as the current situation
and thus cannot cause any regression. Those sites should eventually be
cleaned up in a later patch series.

Lidong Yan e3378607c8 pull: add pull.autoStash config option
Git uses `rebase.autostash` or `merge.autostash` to determine whether a
dirty worktree is allowed during pull. However, this behavior is not
clearly documented, making it difficult for users to discover how to
enable autostash, or causing them to unknowingly enable it. Add new
config option `pull.autostash` along with its documentation and test
cases.

`pull.autostash` provides the same functionality as `rebase.autostash`
and `merge.autostash`, but overrides them when set. If `pull.autostash`
is not set, it falls back to `rebase.autostash` or `merge.autostash`,
depending on the value of `pull.rebase`.

brian m. carlson 1f0fed312a SubmittingPatches: allow non-real name contributions
Our submission guidelines require people to use their real name, but
this is not always suitable for various reasons.

For people who are transgender or non-binary and are transitioning or
who think they might want to transition, it can be a major obstacle and
cause major discomfort to require the use of their real name.  This is
made worse by the fact that Git provides no way to change names built
into history, so the use of a deadname is forever.  Our code of conduct
states that we "pledge to act and interact in ways that contribute to an
open, welcoming, diverse, inclusive, and healthy community," and
changing this policy is one way we can improve things for contributors.

In addition, there are some developers who are so widely known
pseudonymously that they have a Wikipedia page with their handle and no
real name.  It would seem silly to reject patches from people who are
known and respected in their open-source community just because they
don't wish to share a real name.

There are also other good reasons why people might operate
pseudonymously: because they or their family members are well known and
they wish to protect their privacy, because of current or past
harassment or retaliation or fear of that happening in the future, or
because of concerns about unwanted attention from government officials
or other authority figures.  As much as possible, we want to welcome
contributions from anyone who is willing to participate positively in
our community without having them worry about their safety or privacy.

In all of these cases, we should allow people to proceed using a
preferred name or pseudonymously if, in their best judgment, that's the
right thing to do.  State that it is common to use a real name but
explicitly mention that contributors who are not comfortable doing so or
prefer to operate pseudonymously or under a preferred name can proceed
otherwise, provided the name is distinctive, identifying, and not
misleading.  For instance, using U+2060 (WORD JOINER) as one's ID would
likely be distinctive but not identifying, since most people would have
trouble reading it due to its zero-width nature.

We prohibit identities which are misleading, since our goal is to create
a community which works together with a common goal, and misleading or
deceiving others is not conducive to good community or compatible with
our code of conduct, nor is it compatible with making a legal assertion
about the provenance of one's code.

Explicitly prohibit anonymous contributions to ensure that we have some
line of provenance to a known (if pseudonymous) author who might be able
to respond to questions about it.  Explain that this is the reason we
have this policy to help contributors understand the rationale better.

Use "some form of your real name" since some current contributors use
shortened forms of their name or use initials, which have always been
considered acceptable.  This helps guide people who would be fine using
their real name but have misconfigured `user.name` thinking it is
intended to be a username or is used for authentication (despite our
documentation to the contrary), but also allows for a variety of
circumstances where the contributor would feel more comfortable not
doing so.

Note that this policy is the same as that of the Linux kernel[0] and the
CNCF[1], as well as many smaller projects.  The Linux kernel patch was
Acked-by one of the Linux Foundation's lawyers, Michael Dolan, so it
appears these changes have had legal review.

Additionally, retain the section header ID for ease of linking across
versions.

Karthik Nayak dabecb9db2 for-each-ref: introduce a '--start-after' option
The `git-for-each-ref(1)` command is used to iterate over references
present in a repository. In large repositories with millions of
references, it would be optimal to paginate this output such that we
can start iteration from a given reference. This would avoid having to
iterate over all references from the beginning each time when paginating
through results.

The previous commit added 'seek' functionality to the reference
backends. Utilize this and expose a '--start-after' option in
'git-for-each-ref(1)'. When used, the reference iteration seeks to the
lexicographically next reference and iterates from there onward.

This enables efficient pagination workflows, where the calling script
can remember the last provided reference and use that as the starting
point for the next set of references:
    git for-each-ref --count=100
    git for-each-ref --count=100 --start-after=refs/heads/branch-100
    git for-each-ref --count=100 --start-after=refs/heads/branch-200

Since the reference iterators only allow seeking to a specified marker
via the `ref_iterator_seek()`, we introduce a helper function
`start_ref_iterator_after()`, which seeks to next reference by simply
adding (char) 1 to the marker.

We must note that pagination always continues from the provided marker,
as such any concurrent reference updates lexicographically behind the
marker will not be output. Document the same.

Christian Couder b5b3ddbe5c fast-(import|export): improve on commit signature output format
A recent commit, d9cb0e6ff8 (fast-export, fast-import: add support for
signed-commits, 2025-03-10), added support for signed commits to
fast-export and fast-import.

When a signed commit is processed, fast-export can output either
"gpgsig sha1" or "gpgsig sha256" depending on whether the signed
commit uses the SHA-1 or SHA-256 Git object format.

However, this implementation has a number of limitations:

  - the output format was not properly described in the documentation,
  - the output format is not very informative as it doesn't even say
    if the signature is an OpenPGP, an SSH, or an X509 signature,
  - the implementation doesn't support having both one signature on
    the SHA-1 object and one on the SHA-256 object.

Let's improve on these limitations by improving fast-export and
fast-import so that:

  - all the signatures are exported,
  - at most one signature on the SHA-1 object and one on the SHA-256
    are imported,
  - if there is more than one signature on the SHA-1 object or on
    the SHA-256 object, fast-import emits a warning for each
    additional signature,
  - the output format is "gpgsig <git-hash-algo> <signature-format>",
    where <git-hash-algo> is the Git object format as before, and
    <signature-format> is the signature type ("openpgp", "x509",
    "ssh" or "unknown"),
  - the output is properly documented.

About the output format:

  - <git-hash-algo> allows to know which representation of the commit
    was signed (the SHA-1 or the SHA-256 version) which helps with
    both signature verification and interoperability between repos
    with different hash functions,

  - <signature-format> helps tools that process the fast-export
    stream, so they don't have to parse the ASCII armor to identify
    the signature type.

It could be even better to be able to import more than one signature
on the SHA-1 object and on the SHA-256 object, but other parts of
Git don't handle that well for now, so this is left for future
improvements.

Patrick Steinhardt ad7780b38f docs/git-pack-refs: document heuristic used for packing loose refs
The `git pack-refs --auto` flag asks the ref backend to decide for
itself whether or not references need to be repacked. This is done to
ensure that we don't repack in cases where the backend is already in a
good-enough state, which is typically the case for the "reftable"
backend that performs auto-compaction on writes.

As such, we initially only had heuristics in place for the "reftable"
backend. The "files" backend didn't have any heuristics, so we'd repack
loose references every time `git pack-refs --auto` was executed. This
caused excessive repacking with that backend though, which is why we
eventually implemented a heuristic via c3459ae9ef (refs/files: use
heuristic to decide whether to repack with `--auto`, 2024-09-04).

The documentation for the `--auto` flag hasn't been updated accordingly
and still claims that we don't have any metrics for the "files" backend.
Update it to reflect the new reality.

Taylor Blau 7f5dd143ac Documentation/RelNotes: use .adoc extension for new security releases
When preparing the latest round of security fixes, we wrote release
notes in v2.43.7, and then successively merged those up through to the
various 'maint' branches.

However, the 2.49 release series is the first to have commit 1f010d6bdf
(doc: use .adoc extension for AsciiDoc files, 2025-01-20). This means
that we should have renamed the new-but-historical release notes from
*.txt to *.adoc during the merge into the 'maint-2.49' branch, but
neglected to do so.

Rename them accordingly to match the convention introduced by
1f010d6bdf. Since the release materials in question here were prepared
before v2.50.0 was tagged, the 'maint' track for that release series is
OK as is.

Patrick Steinhardt 793b14e1c8 setup: use "reftable" format when experimental features are enabled
With the preceding commit we have announced the switch to the "reftable"
format in Git 3.0 for newly created repositories. The format is being
battle tested by GitLab and a couple of other developers, and except for
a small handful of issues exposed early after it has been merged it has
been rock solid. Regardless of that though the test user base is still
comparatively small, which increases the risk that we miss critical
bugs.

Address this by enabling the reftable format when experimental features
are enabled. This should increase the test user base by some margin and
thus give us more input before making the format the default.

the reftable backend so that we don't break all applications and tools

Taylor Blau 5ee86c273b repack: exclude cruft pack(s) from the MIDX where possible
In ddee3703b3 (builtin/repack.c: add cruft packs to MIDX during
geometric repack, 2022-05-20), repack began adding cruft pack(s) to the
MIDX with '--write-midx' to ensure that the resulting MIDX was always
closed under reachability in order to generate reachability bitmaps.

While the previous patch added the '--stdin-packs=follow' option to
pack-objects, it is not yet on by default. Given that, suppose you have
a once-unreachable object packed in a cruft pack, which later becomes
reachable from one or more objects in a geometrically repacked pack.
That once-unreachable object *won't* appear in the new pack, since the
cruft pack was not specified as included or excluded when the
geometrically repacked pack was created with 'pack-objects
--stdin-packs' (*not* '--stdin-packs=follow', which is not on). If that
new pack is included in a MIDX without the cruft pack, then trying to
generate bitmaps for that MIDX may fail. This happens when the bitmap
selection process picks one or more commits which reach the
once-unreachable objects.

To mitigate this failure mode, commit ddee3703b3 ensures that the MIDX
will be closed under reachability by including cruft pack(s). If cruft
pack(s) were not included, we would fail to generate a MIDX bitmap. But
ddee3703b3 alludes to the fact that this is sub-optimal by saying

    [...] it's desirable to avoid including cruft packs in the MIDX
    because it causes the MIDX to store a bunch of objects which are
    likely to get thrown away.

, which is true, but hides an even larger problem. If repositories
rarely prune their unreachable objects and/or have many of them, the
MIDX must keep track of a large number of objects which bloats the MIDX
and slows down object lookup.

This is doubly unfortunate because the vast majority of objects in cruft
pack(s) are unlikely to be read. But any object lookups that go through
the MIDX must binary search over them anyway, slowing down object
lookups using the MIDX.

This patch causes geometrically-repacked packs to contain a copy of any
once-unreachable object(s) with 'git pack-objects --stdin-packs=follow',
allowing us to avoid including any cruft packs in the MIDX. This is
because a sequence of geometrically-repacked packs that were all
generated with '--stdin-packs=follow' are guaranteed to have their union
be closed under reachability.

Note that you cannot guarantee that a collection of packs is closed
under reachability if not all of them were generated with "following" as
above. One tell-tale sign that not all geometrically-repacked packs in
the MIDX were generated with "following" is to see if there is a pack in
the existing MIDX that is not going to be somehow represented (either
verbatim or as part of a geometric rollup) in the new MIDX.

If there is, then starting to generate packs with "following" during
geometric repacking won't work, since it's open to the same race as
described above.

But if you're starting from scratch (e.g., building the first MIDX after
an all-into-one '--cruft' repack), then you can guarantee that the union
of subsequently generated packs from geometric repacking *is* closed
under reachability.

(One exception here is when "starting from scratch" results in a noop
repack, e.g., because the non-cruft pack(s) in a repository already form
a geometric progression. Since we can't tell whether or not those were
generated with '--stdin-packs=follow', they may depend on
once-unreachable objects, so we have to include the cruft pack in the
MIDX in this case.)

Detect when this is the case and avoid including cruft packs in the MIDX
where possible. The existing behavior remains the default, and the new
behavior is available with the config 'repack.midxMustIncludeCruft' set
to 'false'.

Taylor Blau cd846bacc7 pack-objects: introduce '--stdin-packs=follow'
When invoked with '--stdin-packs', pack-objects will generate a pack
which contains the objects found in the "included" packs, less any
objects from "excluded" packs.

Packs that exist in the repository but weren't specified as either
included or excluded are in practice treated like the latter, at least
in the sense that pack-objects won't include objects from those packs.
This behavior forces us to include any cruft pack(s) in a repository's
multi-pack index for the reasons described in ddee3703b3
(builtin/repack.c: add cruft packs to MIDX during geometric repack,
2022-05-20).

The full details are in ddee3703b3, but the gist is if you
have a once-unreachable object in a cruft pack which later becomes
reachable via one or more commits in a pack generated with
'--stdin-packs', you *have* to include that object in the MIDX via the
copy in the cruft pack, otherwise we cannot generate reachability
bitmaps for any commits which reach that object.

Note that the traversal here is best-effort, similar to the existing
traversal which provides name-hash hints. This means that the object
traversal may hand us back a blob that does not actually exist. We
*won't* see missing trees/commits with 'ignore_missing_links' because:

 - missing commit parents are discarded at the commit traversal stage by
   revision.c::process_parents()

 - missing tag objects are discarded by revision.c::handle_commit()

 - missing tree objects are discarded by the list-objects code in
   list-objects.c::process_tree()

But we have to handle potentially-missing blobs specially by making a
separate check to ensure they exist in the repository. Failing to do so
would mean that we'd add an object to the packing list which doesn't
actually exist, rendering us unable to write out the pack.

This prepares us for new repacking behavior which will "resurrect"
objects found in cruft or otherwise unspecified packs when generating
new packs. In the context of geometric repacking, this may be used to
maintain a sequence of geometrically-repacked packs, the union of which
is closed under reachability, even in the case described earlier.

Aditya Garg 067a91b03f imap-send: add ability to list the available folders
Various IMAP servers have different ways to name common folders.
For example, the folder where all deleted messages are stored is often
named "[Gmail]/Trash" on Gmail servers, and "Deleted" on Outlook.
Similarly, the Drafts folder is simply named "Drafts" on Outlook, but
on Gmail it is named "[Gmail]/Drafts".

This commit adds a `--list` command to the `imap-send` tool that lists
the available folders on the IMAP server, allowing users to see
which folders are available and how they are named. A sample output
looks like this when run against a Gmail server:

    Fetching the list of available folders...
    * LIST (\HasNoChildren) "/" "INBOX"
    * LIST (\HasChildren \Noselect) "/" "[Gmail]"
    * LIST (\All \HasNoChildren) "/" "[Gmail]/All Mail"
    * LIST (\Drafts \HasNoChildren) "/" "[Gmail]/Drafts"
    * LIST (\HasNoChildren \Important) "/" "[Gmail]/Important"
    * LIST (\HasNoChildren \Sent) "/" "[Gmail]/Sent Mail"
    * LIST (\HasNoChildren \Junk) "/" "[Gmail]/Spam"
    * LIST (\Flagged \HasNoChildren) "/" "[Gmail]/Starred"
    * LIST (\HasNoChildren \Trash) "/" "[Gmail]/Trash"

For OpenSSL, this is achived by running the 'IMAP LIST' command and
parsing the response. This command is specified in RFC6154:
https://datatracker.ietf.org/doc/html/rfc6154#section-5.1

For libcurl, the example code published in the libcurl documentation
is used to implement this functionality:

Junio C Hamano c8b4805897 merge/pull: extend merge.stat configuration variable to cover --compact-summary
Existing `merge.stat` configuration variable is a Boolean that
defaults to `true` to control `git merge --[no-]stat` behaviour.

Extend it to be "Boolean or text", that takes false, true, or
"compact", with the last one triggering the --compact-summary option
introduced earlier.  Any other values are taken as the same as true,
instead of signaling an error---it is not a grave enough offence to
stop their merge.

Junio C Hamano 3a54f5bd5d merge/pull: add the "--compact-summary" option
"git merge" and "git pull" shows "git diff --stat --summary @{1}"
when they finish to indicate the extent of the changes brought into
the history by default.  While it gives a good overview, it becomes
annoying when there are very many created or deleted paths.

Introduce "--compact-summary" option to these two commands that
tells it to instead show "git diff --compact-summary @{1}", which
gives the same information in a lot more compact form in such a
situation.

brian m. carlson bc303718cc builtin/stash: provide a way to import stashes from a ref
Now that we have a way to export stashes to a ref, let's provide a way
to import them from such a ref back to the stash.  This works much the
way the export code does, except that we strip off the first parent
chain commit and then store each resulting commit back to the stash.

We don't clear the stash first and instead add the specified stashes to
the top of the stash.  This is because users may want to export just a
few stashes, such as to share a small amount of work in progress with a
colleague, and it would be undesirable for the receiving user to lose
all of their data.  For users who do want to replace the stash, it's
easy to do to: simply run "git stash clear" first.

We specifically rely on the fact that we'll produce identical stash
commits on both sides in our tests.  This provides a cheap,
straightforward check for our tests and also makes it easy for users to
see if they already have the same data in both repositories.

brian m. carlson 27c0be9a3f builtin/stash: provide a way to export stashes to a ref
A common user problem is how to sync in-progress work to another
machine.  Users currently must use some sort of transfer of the working
tree, which poses security risks and also necessarily causes the index
to become dirty.  The experience is suboptimal and frustrating for
users.

A reasonable idea is to use the stash for this purpose, but the stash is
stored in the reflog, not in a ref, and as such it cannot be pushed or
pulled.  This also means that it cannot be saved into a bundle or
preserved elsewhere, which is a problem when using throwaway development
environments.

In addition, users often want to replicate stashes across machines, such
as when they must use multiple machines or when they use throwaway dev
environments, such as those based on the Devcontainer spec, where they
might otherwise lose various in-progress work.

Let's solve this problem by allowing the user to export the stash to a
ref (or, to just write it into the repository and print the hash, à la
git commit-tree).  Introduce git stash export, which writes a chain of
commits where the first parent is always a chain to the previous stash,
or to a single, empty commit (for the final item) and the second is the
stash commit normally written to the reflog.

Iterate over each stash from top to bottom, looking up the data for each
one, and then create the chain from the single empty commit back up in
reverse order.  Generate a predictable empty commit so our behavior is
reproducible.  Create a useful commit message, preserving the author and
committer information, to help users identify stash commits when viewing
them as normal commits.

If the user has specified specific stashes they'd like to export
instead, use those instead of iterating over all of the stashes.

As part of this, specifically request quiet behavior when looking up the
OID for a revision because we will eventually hit a revision that
doesn't exist and we don't want to die when that occurs.

When exporting stashes, be sure to verify that they look like valid
stashes and don't contain invalid data.  This will help avoid failures
on import or problems due to attempting to export invalid refs that are
not stashes.

Commit 0b080a70ab (doc: git-diff: apply format changes to

  mode <mode>,<mode>..<mode>

in backticks. Note how the line before is quite similar,

  index <hash>,<hash>..<hash>

but did not get any backticks. Remove the backticks, since they confuse
Asciidoctor.

The exact failure mode changed with c87b2b3a6f (doc: fix asciidoctor
synopsis processing of triple-dots, 2025-04-12), and arguably to the
better. But Asciidoctor (2.0.18) still ends up confused by these
backticks and leaves the manpage rendering as

  index <hash>,<hash>..<hash>
  mode <mode>,<mode>`..__<mode>__
  {empty}`new file mode <mode>

Drop the backticks. This is a no-op with asciidoc (10.2.0).

Victoria Dye b0b910e052 cat-file.c: add batch handling for submodules
When an object specification is passed to 'cat-file --batch[-check]'
referring to a submodule (e.g. 'HEAD:path/to/my/submodule'), the current
behavior of the command is to print the "missing" error message. However, it
is often valuable for callers to distinguish between paths that are actually
missing and "the submodule tree entry exists, but the object does not exist
in the repository".

To disambiguate without needing to invoke a separate Git process (e.g.
'ls-tree'), print the message "<oid> submodule" for such objects instead of
"<object> missing". In addition to the change from "missing" to "submodule",
the new message differs from the old in that it always prints the resolved
tree entry's OID, rather than the input object specification.

Note that this implementation maintains a distinction between submodules
where the commit OID is not present in the repo, and submodules where the
commit OID *is* present; the former will now print "<object> submodule", but
the latter will still print the full object content.

Add the parameter `struct repository *repo` to the cmd_walken function.

Since commit 9b1cb5070f (builtin: add a repository parameter for
builtin functions, 2024-09-13), all the cmd_* have the `repo` parameter
and new commands must follow this convention, so the documentation
should also be changed.

Change the `git_config` calls to `repo_config`, also passing the `repo`
parameter, as since 036876a106 (config: hide functions using
`the_repository` by default, 2024-08-13) the non-repo config functions
are no longer recommended as they use the global `repository` variable.

Aditya Garg 9e68aaba45 docs: make the purpose of using app password for Gmail more clear in send-email
The current example for Gmail suggests using app passwords for
send-email if user has multi-factor authentication set up for their
account. However, it does not clarify that the user cannot use their
normal password in case they do not have multi-factor authentication
enabled. Most likely the example was written in the days when Google
allowed using normal passwords without multi-factor authentication.

Clarify that regular passwords do not work for Gmail and app-passwords
are the only way for basic authentication. Also encourage users to use
OAuth2.0 as a more secure alternative.

While at it, also prefer using the word "mechanism" over "method" for
`OAUTHBEARER` and `XOAUTH2` since that is what official docs use.

docs don't even talk about send emails, thus confirming this view.

So, lets remove these links from the gitcredentials page. The links are

Junio C Hamano 0b4c6baa70 fast-export: --signed-commits is experimental
As the design of signature handling is still being discussed, it is
likely that the data stream produced by the code in Git 2.50 would
have to be changed in such a way that is not backward compatible.

Mark the feature as experimental and discourge its use for now.

Also flip the default on the generation side to "strip"; users of
existing versions would not have passed --signed-commits=strip and
will be broken by this change if the default is made to abort, and
will be encouraged by the error message to produce data stream with
future breakage guarantees by passing --signed-commits option.

As we tone down the default behaviour, we no longer need the
FAST_EXPORT_SIGNED_COMMITS_NOABORT environment variable, which was
not discoverable enough.

46538012d9 (notes remove: --stdin reads from the standard input,
2011-05-18) added `--stdin` for the `remove` subcommand, documenting it
in the “Options” section.  But `copy --stdin` was added before that, in
160baa0d9c (notes: implement 'git notes copy --stdin', 2010-03-12).

Treat this option equally between the two subcommands:

• remove: mention `--stdin` on the subcommand as well, like for `copy`
• copy: mention it as well under the option documentation

Cleaning up whitespace in metadata is typical porcelain behavior and
this default does not need to be pointed out.[1]  Only speak up when
the default `--stripspace` is not used.

Also remove all misleading mentions of comment lines in the process;
see the previous commit.

Also remove the period that trails the parenthetical here.

† 1: See `-F` in git-commit(1) which has nothing to say about whitespace
    cleanup.  The cleanup discussion is on `--cleanup`.

Kristoffer Haugsbakk 6521ca8ec4 doc: notes: rework --[no-]stripspace
Document this option by copying the bullet list from git-stripspace(1).
A bullet list is cleaner when there are this many points to consider.
We also get a more standardized description of the multiple-blank-lines
behavior.  Compare the repeating (git-notes(1)):

    empty lines other than a single line between paragraphs

With (git-stripspace(1)):

    multiple consecutive empty lines

And:

    leading [...] whitespace

With:

    empty lines from the beginning

Leading whitespace in the form of spaces (indentation) are not removed.
However, empty lines at the start of the message are removed.

Note that we drop the mentions of comment line handling because they are
wrong; this option does not control how lines which can be recognized as
comment lines are handled.  Only interactivity controls that:

• Comment lines are stripped after editing interactively
• Lines which could be recognized as comment lines are left alone when
  the message is given non-interactively

So it is misleading to document the comment line behavior on
this option.

Further, the text is wrong:

    Lines starting with `#` will be stripped out in non-editor cases
    like `-m`, [...]

Comment lines are still indirectly discussed on other options.  We will
deal with them in the next commit.

Clarify what happens when an object exists in more than one pack, but
not in the preferred pack. "git multi-pack-index repack" relies on ties
for objects that are not in the preferred pack being resolved in favor
of the newest pack that contains a copy of the object. If ties were
resolved in favor of the oldest pack as the current documentation
suggests the multi-pack index would not reference any of the objects in
the pack created by "git multi-pack-index repack".

Jacob Keller 09fb155f11 diff --no-index: support limiting by pathspec
The --no-index option of git-diff enables using the diff machinery from
git while operating outside of a repository. This mode of git diff is
able to compare directories and produce a diff of their contents.

When operating git diff in a repository, git has the notion of
"pathspecs" which can specify which files to compare. In particular,
when using git to diff two trees, you might invoke:

  $ git diff-tree -r <treeish1> <treeish2>.

where the treeish could point to a subdirectory of the repository.

When invoked this way, users can limit the selected paths of the tree by
using a pathspec. Either by providing some list of paths to accept, or
by removing paths via a negative refspec.

The git diff --no-index mode does not support pathspecs, and cannot
limit the diff output in this way. Other diff programs such as GNU
difftools have options for excluding paths based on a pattern match.
However, using git diff as a diff replacement has several advantages
over many popular diff tools, including coloring moved lines, rename
detections, and similar.

Teach git diff --no-index how to handle pathspecs to limit the
comparisons. This will only be supported if both provided paths are
directories.

For comparisons where one path isn't a directory, the --no-index mode
already has some DWIM shortcuts implemented in the fixup_paths()
function.

Modify the fixup_paths function to return 1 if both paths are
directories. If this is the case, interpret any extra arguments to git
diff as pathspecs via parse_pathspec.

Use parse_pathspec to load the remaining arguments (if any) to git diff
--no-index as pathspec items. Disable PATHSPEC_ATTR support since we do
not have a repository to do attribute lookup. Disable PATHSPEC_FROMTOP
since we do not have a repository root. All pathspecs are treated as
rooted at the provided comparison paths.

After loading the pathspec data, calculate skip offsets for skipping
past the root portion of the paths. This is required to ensure that
pathspecs start matching from the provided path, rather than matching
from the absolute path. We could instead pass the paths as prefix values
to parse_pathspec. This is slightly problematic because the paths come
from the command line and don't necessarily have the proper trailing
slash. Additionally, that would require parsing pathspecs multiple
times.

Pass the pathspec object and the skip offsets into queue_diff, which
in-turn must pass them along to read_directory_contents.

Modify read_directory_contents to check against the pathspecs when
scanning the directory. Use the skip offset to skip past the initial
root of the path, and only match against portions that are below the
intended directory structure being compared.

The search algorithm for finding paths is recursive with read_dir. To
make pathspec matching work properly, we must set both
DO_MATCH_DIRECTORY and DO_MATCH_LEADING_PATHSPEC.

Without DO_MATCH_DIRECTORY, paths like "a/b/c/d" will not match against
pathspecs like "a/b/c". This is usually achieved by setting the is_dir
parameter of match_pathspec.

Without DO_MATCH_LEADING_PATHSPEC, paths like "a/b/c" would not match
against pathspecs like "a/b/c/d". This is crucial because we recursively
iterate down the directories. We could simply avoid checking pathspecs
at subdirectories, but this would force recursion down directories
which would simply be skipped.

If we always passed DO_MATCH_LEADING_PATHSPEC, then we will
incorrectly match in certain cases such as matching 'a/c' against
':(glob)**/d'. The match logic will see that a matches the leading part
of the **/ and accept this even tho c doesn't match.

To avoid this, use the match_leading_pathspec() variant recently
introduced. This sets both flags when is_dir is set, but leaves them
both cleared when is_dir is 0.

Add test cases and documentation covering the new functionality. Note
for the documentation I opted not to move the placement of '--' which is
sometimes used to disambiguate arguments. The diff --no-index mode
requires exactly 2 arguments determining what to compare. Any additional
arguments are interpreted as pathspecs and must come afterwards. Use of
'--' would not actually disambiguate anything, since there will never be
ambiguity over which arguments represent paths or pathspecs.

Justin Tobler 68cb0b5253 builtin/receive-pack: add option to skip connectivity check
During git-receive-pack(1), connectivity of the object graph is
validated to ensure that the received packfile does not leave the
repository in a broken state. This is done via git-rev-list(1) and
walking the objects, which can be expensive for large repositories.

Generally, this check is critical to avoid an incomplete received
packfile from corrupting a repository. Server operators may have
additional knowledge though around exactly how Git is being used on the
server-side which can be used to facilitate more efficient connectivity
computation of incoming objects.

For example, if it can be ensured that all objects in a repository are
connected and do not depend on any missing objects, the connectivity of
newly written objects can be checked by walking the object graph
containing only the new objects from the updated tips and identifying
the missing objects which represent the boundary between the new objects
and the repository. These boundary objects can be checked in the
canonical repository to ensure the new objects connect as expected and
thus avoid walking the rest of the object graph.

Git itself cannot make the guarantees required for such an optimization
as it is possible for a repository to contain an unreachable object that
references a missing object without the repository being considered
corrupt.

Introduce the --skip-connectivity-check option for git-receive-pack(1)
which bypasses this connectivity check to give more control to the
server-side. Note that without proper server-side validation of newly
received objects handled outside of Git, usage of this option risks
corrupting a repository.

Derrick Stolee 4f7f571204 pack-objects: enable --path-walk via config
Users may want to enable the --path-walk option for 'git pack-objects' by
default, especially underneath commands like 'git push' or 'git repack'.

This should be limited to client repositories, since the --path-walk option
disables bitmap walks, so would be bad to include in Git servers when
serving fetches and clones. There is potential that it may be helpful to
consider when repacking the repository, to take advantage of improved deltas
across historical versions of the same files.

Much like how "pack.useSparse" was introduced and included in
"feature.experimental" before being enabled by default, use the repository
settings infrastructure to make the new "pack.usePathWalk" config enabled by
"feature.experimental" and "feature.manyFiles".

In order to test that this config works, add a new trace2 region around
the path walk code that can be checked by a 'git push' command.

Derrick Stolee 5f711504d9 repack: add --path-walk option
Since 'git pack-objects' supports a --path-walk option, allow passing it
through in 'git repack'. This presents interesting testing opportunities for
comparing the different repacking strategies against each other.

Add the --path-walk option to the performance tests in p5313.

For the microsoft/fluentui repo [1] checked out at a specific commit [2],
the --path-walk tests in p5313 look like this:

Test                                                     this tree

5313.25: repack size with --path-walk                             142.5M

[2] e70848ebac1cd720875bccaa3026f4a9ed700e08

Along with the earlier tests in p5313, I'll instead reformat the
comparison as follows:

Repack Method    Pack Size       Time
---------------------------------------
Hash v1             439.4M      87.24s
Hash v2             161.7M      21.51s
Path Walk           142.5M      81.29s

There are a few things to notice here:

 1. The benefits of --name-hash-version=2 over --name-hash-version=1 are
    significant, but --path-walk still compresses better than that
    option.

 2. The --path-walk command is still using --name-hash-version=1 for the
    second pass of delta computation, using the increased name hash
    collisions as a potential method for opportunistic compression on
    top of the path-focused compression.

 3. The --path-walk algorithm is currently sequential and does not use
    multiple threads for delta compression. Threading will be
    implemented in a future change so the computation time will improve
    to better compete in this metric.

There are small benefits in size for my copy of the Git repository:

Repack Method    Pack Size       Time
---------------------------------------
Hash v1             248.8M      30.44s
Hash v2             249.0M      30.15s
Path Walk           213.2M     142.50s

As well as in the nodejs/node repository [3]:

Repack Method    Pack Size       Time
---------------------------------------
Hash v1             739.9M      71.18s
Hash v2             764.6M      67.82s
Path Walk           698.1M     208.10s

[3] https://github.com/nodejs/node

This benefit also repeats in my copy of the Linux kernel repository:

Repack Method    Pack Size       Time
---------------------------------------
Hash v1               2.5G     554.41s
Hash v2               2.5G     549.62s
Path Walk             2.2G    1562.36s

It is important to see that even when the repository shape does not have
many name-hash collisions, there is a slight space boost to be found
using this method.

As this repacking strategy was released in Git for Windows 2.47.0, some
users have reported cases where the --path-walk compression is slightly
worse than the --name-hash-version=2 option. In those cases, it may be
beneficial to combine the two options. However, there has not been a
released version of Git that has both options and I don't have access to
these repos for testing.

Derrick Stolee 70664d2865 pack-objects: add --path-walk option
In order to more easily compute delta bases among objects that appear at
the exact same path, add a --path-walk option to 'git pack-objects'.

This option will use the path-walk API instead of the object walk given
by the revision machinery. Since objects will be provided in batches
representing a common path, those objects can be tested for delta bases
immediately instead of waiting for a sort of the full object list by
name-hash. This has multiple benefits, including avoiding collisions by
name-hash.

The objects marked as UNINTERESTING are included in these batches, so we
are guaranteeing some locality to find good delta bases.

After the individual passes are done on a per-path basis, the default
name-hash is used to find other opportunistic delta bases that did not
match exactly by the full path name.

The current implementation performs delta calculations while walking
objects, which is not ideal for a few reasons. First, this will cause
the "Enumerating objects" phase to be much longer than usual. Second, it
does not take advantage of threading during the path-scoped delta
calculations. Even with this lack of threading, the path-walk option is
sometimes faster than the usual approach. Future changes will refactor
this code to allow for threading, but that complexity is deferred until
later to keep this patch as simple as possible.

This new walk is incompatible with some features and is ignored by
others:

 * Object filters are not currently integrated with the path-walk API,
   such as sparse-checkout or tree depth. A blobless packfile could be
   integrated easily, but that is deferred for later.

 * Server-focused features such as delta islands, shallow packs, and
   using a bitmap index are incompatible with the path-walk API.

 * The path walk API is only compatible with the --revs option, not
   taking object lists or pack lists over stdin. These alternative ways
   to specify the objects currently ignores the --path-walk option
   without even a warning.

Future changes will create performance tests that demonstrate the power
of this approach.

Jeff King f227fc7d43 cat-file: make --allow-unknown-type a noop
The cat-file command has some minor support for handling objects with
"unknown" types. I.e., strings that are not "blob", "commit", "tree", or
"tag".

In theory this could be used for debugging or experimenting with
extensions to Git. But in practice this support is not very useful:

  1. You can get the type and size of such objects, but nothing else.
     Not even the contents!

  2. Only loose objects are supported, since packfiles use numeric ids
     for the types, rather than strings.

  3. Likewise you cannot ever transfer objects between repositories,
     because they cannot be represented in the packfiles used for the
     on-the-wire protocol.

The support for these unknown types complicates the object-parsing code,
and has led to bugs such as b748ddb7a4 (unpack_loose_header(): fix
infinite loop on broken zlib input, 2025-02-25). So let's drop it.

The first step is to remove the user-facing parts, which are accessible
only via cat-file. This is technically backwards-incompatible, but given
the limitations listed above, these objects couldn't possibly be useful
in any workflow.

However, we can't just rip out the option entirely. That would hurt a
caller who ran:

  git cat-file -t --allow-unknown-object <oid>

and fed it normal, well-formed objects. There --allow-unknown-type was
doing nothing, but we wouldn't want to start bailing with an error. So
to protect any such callers, we'll retain --allow-unknown-type as a
noop.

The code change is fairly small (but we'll able to clean up more code in
follow-on patches). The test updates drop any use of the option. We
still retain tests that feed the broken objects to cat-file without
--allow-unknown-type, as we should continue to confirm that those
objects are rejected. Note that in one spot we can drop a layer of loop,
re-indenting the body; viewing the diff with "-w" helps there.
