Add retry logic for HTTP 429 (Too Many Requests) responses to handle
server-side rate limiting gracefully. When Git's HTTP client receives
a 429 response, it can now automatically retry the request after an
appropriate delay, respecting the server's rate limits.
The implementation supports the RFC-compliant Retry-After header in
both delay-seconds (integer) and HTTP-date (RFC 2822) formats. If a
past date is provided, Git retries immediately without waiting.
Retry behavior is controlled by three new configuration options
(http.maxRetries, http.retryAfter, and http.maxRetryTime) which are
documented in git-config(1).
The retry logic implements a fail-fast approach: if any delay
(whether from server header or configuration) exceeds maxRetryTime,
Git fails immediately with a clear error message rather than capping
the delay. This provides better visibility into rate limiting issues.
The implementation includes extensive test coverage for basic retry
behavior, Retry-After header formats (integer and HTTP-date),
configuration combinations, maxRetryTime limits, invalid header
handling, environment variable overrides, and edge cases.

For SMTP servers that do "mutual certificate verification", the mail
client is required to present its own TLS certificate as well. This
patch adds --smtp-ssl-client-cert and --smtp-ssl-client-key for such
servers.
The problem of which private key for the certificate is chosen arises
when there are private keys in both the certificate and private key
file. According to the documentation of IO::Socket::SSL(link supplied),
the behaviour(the private key chosen) depends on the format of the
certificate. In a nutshell,
- PKCS12: the key in the cert always takes the precedence
- PEM: if the key file is not given, it will "try" to read one
from the cert PEM file
Many users may find this discrepancy unintuitive.
In terms of client certificate, git-send-email is implemented in a way
that what's possible with perl's SSL library is exposed to the user as
much as possible. In this instance, the user may choose to use a PEM
file that contains both certificate and private key should be
at their discretion despite the implications.

Add a new configuration variable status.compareBranches that allows
users to specify a space-separated list of branch comparisons in
git status output.
Supported values:
- @{upstream} for the current branch's upstream tracking branch
- @{push} for the current branch's push destination
Any other value is ignored and a warning is shown.
When not configured, the default behavior is equivalent to setting
`status.compareBranches = @{upstream}`, preserving backward
compatibility.
The advice messages shown are context-aware:
- "git pull" advice is shown only when comparing against @{upstream}
- "git push" advice is shown only when comparing against @{push}
- Divergence advice is shown for upstream branch comparisons
This is useful for triangular workflows where the upstream tracking
branch differs from the push destination, allowing users to see their
status relative to both branches at once.
Example configuration:
[status]
compareBranches = @{upstream} @{push}

The 'extensions.refStorage' config is used to specify the reference
backend for a given repository. Both the 'files' and 'reftable' backends
utilize the $GIT_DIR as the reference folder by default in
`get_main_ref_store()`.
Since the reference backends are pluggable, this means that they could
work with out-of-tree reference directories too. Extend the 'refStorage'
config to also support taking an URI input, where users can specify the
reference backend and the location.
Add the required changes to obtain and propagate this value to the
individual backends. Add the necessary documentation and tests.
Traditionally, for linked worktrees, references were stored in the
'$GIT_DIR/worktrees/<wt_id>' path. But when using an alternate reference
storage path, it doesn't make sense to store the main worktree
references in the new path, and the linked worktree references in the
$GIT_DIR. So, let's store linked worktree references in
'$ALTERNATE_REFERENCE_DIR/worktrees/<wt_id>'. To do this, create the
necessary files and folders while also adding stubs in the $GIT_DIR path
to ensure that it is still considered a Git directory.
Ideally, we would want to pass in a `struct worktree *` to individual
backends, instead of passing the `gitdir`. This allows them to handle
worktree specific logic. Currently, that is not possible since the
worktree code is:
- Tied to using the global `the_repository` variable.
- Is not setup before the reference database during initialization of
the repository.
Add a TODO in 'refs.c' to ensure we can eventually make that change.

The git-gc(1) command has been introduced in the early days of Git in
30f610b7b0 (Create 'git gc' to perform common maintenance operations.,
2006-12-27) as the main repository maintenance utility. And while the
tool has of course evolved since then to cover new parts, the basic
strategy it uses has never really changed much.
It is safe to say that since 2006 the Git ecosystem has changed quite a
bit. Repositories tend to be much larger nowadays than they have been
almost 20 years ago, and large parts of the industry went crazy for
monorepos (for various wildly different definitions of "monorepo"). So
the maintenance strategy we used back then may not be the best fit
nowadays anymore.
Arguably, most of the maintenance tasks that git-gc(1) does are still
perfectly fine today: repacking references, expiring various data
structures and things like tend to not cause huge problems. But the big
exception is the way we repack objects.
git-gc(1) by default uses a split strategy: it performs incremental
repacks by default, and then whenever we have too many packs we perform
a large all-into-one repack. This all-into-one repack is what is causing
problems nowadays, as it is an operation that is quite expensive. While
it is wasteful in small- and medium-sized repositories, in large repos
it may even be prohibitively expensive.
We have eventually introduced git-maintenance(1) that was slated as a
replacement for git-gc(1). In contrast to git-gc(1), it is much more
flexible as it is structured around configurable tasks and strategies.
So while its default "gc" strategy still uses git-gc(1) under the hood,
it allows us to iterate.
A second strategy it knows about is the "incremental" strategy, which we
configure when registering a repository for scheduled maintenance. This
strategy isn't really a full replacement for git-gc(1) though, as it
doesn't know to expire unused data structures. In Git 2.52 we have thus
introduced a new "geometric" strategy that is a proper replacement for
the old git-gc(1).
In contrast to the incremental/all-into-one split used by git-gc(1), the
new "geometric" strategy maintains a geometric progression of packfiles,
which significantly reduces the number of all-into-one repacks that we
have to perform in large repositories. It is thus a much better fit for
large repositories than git-gc(1).
Note that the "geometric" strategy isn't perfect though: while we
perform way less all-into-one repacks compared to git-gc(1), we still
have to perform them eventually. But for the largest repositories out
there this may not be an option either, as client machines might not be
powerful enough to perform such a repack in the first place. These cases
would thus still be covered by the "incremental" strategy.
Switch the default strategy away from "gc" to "geometric", but retain
the "incremental" strategy configured when registering background
maintenance with `git maintenance register`.

Teach the hook.[hc] library to parse configs to populate the list of
hooks to run for a given event.
Multiple commands can be specified for a given hook by providing
"hook.<friendly-name>.command = <path-to-hook>" and
"hook.<friendly-name>.event = <hook-event>" lines.
Hooks will be started in config order of the "hook.<name>.event"
lines and will be run sequentially (.jobs == 1) like before.
Running the hooks in parallel will be enabled in a future patch.
The "traditional" hook from the hookdir is run last, if present.
A strmap cache is added to struct repository to avoid re-reading
the configs on each rook run. This is useful for hooks like the
ref-transaction which gets executed multiple times per process.
Examples:
$ git config --get-regexp "^hook\."
hook.bar.command=~/bar.sh
hook.bar.event=pre-commit
# Will run ~/bar.sh, then .git/hooks/pre-commit

The "pack.preferBitmapTips" configuration allows the user to specify
which references should be preferred when generating bitmaps. This
option is typically expected to be set to a reference prefix, like for
example "refs/heads/".
It's not unreasonable though for a user to configure one specific
reference as preferred. But if they do, they'll hit a `BUG()`:
$ git -c pack.preferBitmapTips=refs/heads/main repack -adb
BUG: ../refs/iterator.c:366: attempt to trim too many characters
error: pack-objects died of signal 6
The root cause for this bug is how we enumerate these references. We
call `refs_for_each_ref_in()`, which will:
- Yield all references that have a user-specified prefix.
- Trim each of these references so that the prefix is removed.
Typically, this function is called with a trailing slash, like
"refs/heads/", and in that case things work alright. But if the function
is called with the name of an existing reference then we'll try to trim
the full reference name, which would leave us with an empty name. And as
this would not really leave us with anything sensible, we call `BUG()`
instead of yielding this reference.
One could argue that this is a bug in `refs_for_each_ref_in()`. But the
question then becomes what the correct behaviour would be:
- Do we want to skip exact matches? In our case we certainly don't
want that, as the user has asked us to generate a bitmap for it.
- Do we want to yield the reference with the empty refname? That would
lead to a somewhat weird result.
Neither of these feel like viable options, so calling `BUG()` feels like
a sensible way out. The root cause ultimately is that we even try to
trim the whole refname in the first place. There are two possible ways
to fix this issue:
- We can fix the bug by using `refs_for_each_fullref_in()` instead,
which does not strip the prefix at all. Consequently, we would now
start to accept all references that start with the configured
prefix, including exact matches. So if we had "refs/heads/main", we
would both match "refs/heads/main" and "refs/heads/main-branch".
- Or we can fix the bug by appending a slash to the prefix if it
doesn't already have one. This would mean that we only match
ref hierarchies that start with this prefix.
While the first fix leaves the user with strictly _more_ configuration
options, we have already fixed a similar case in 10e8a9352b (refs.c:
stop matching non-directory prefixes in exclude patterns, 2025-03-06) by
using the second option. So for the sake of consistency, let's apply the
same fix here.
Clarify the documentation accordingly.

Git alias names are limited to ASCII alphanumeric characters and
dashes because aliases are implemented as config variable names.
This prevents aliases being created in languages using characters outside that range.
Add support for arbitrary alias names by using config subsections:
[alias "förgrena"]
command = branch
The subsection name is matched as-is (case-sensitive byte comparison),
while the existing definition without a subsection (e.g.,
"[alias] co = checkout") remains case-insensitive for backward
compatibility. This uses existing config infrastructure since
subsections already support arbitrary bytes, and avoids introducing
Unicode normalization.
Also teach the help subsystem about the new syntax so that "git help
-a" properly lists subsection aliases and the autocorrect feature can
suggest them. Use utf8_strwidth() instead of strlen() for column
alignment so that non-ASCII alias names display correctly.

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.
Another previous commit, c213820c51 (promisor-remote: allow a client
to check fields, 2025-09-08), has made it possible for a client to
decide if it accepts a promisor remote advertised by a server based
on these additional fields.
Often though, it would be interesting for the client to just store in
its configuration files these additional fields passed by the server,
so that it can use them when needed.
For example if a token is necessary to access a promisor remote, that
token could be updated frequently only on the server side and then
passed to all the clients through the "promisor-remote" capability,
avoiding the need to update it on all the clients manually.
Storing the token on the client side makes sure that the token is
available when the client needs to access the promisor remotes for a
lazy fetch.
To allow this, let's introduce a new "promisor.storeFields"
configuration variable.
Note that for a partial clone filter, it's less interesting to have
it stored on the client. This is because a filter should be used
right away and we already pass a `--filter=<filter-spec>` option to
`git clone` when starting a partial clone. Storing the filter could
perhaps still be interesting for information purposes.
Like "promisor.checkFields" and "promisor.sendFields", the new
configuration variable should contain a comma or space separated list
of field names. Only the "partialCloneFilter" and "token" field names
are supported for now.
When a server advertises a promisor remote, for example "foo", along
with for example "token=XXXXX" to a client, and on the client side
"promisor.storeFields" contains "token", then the client will store
XXXXX for the "remote.foo.token" variable in its configuration file
and reload its configuration so it can immediately use this new
configuration variable.
A message is emitted on stderr to warn users when the config is
changed.
Note that even if "promisor.acceptFromServer" is set to "all", a
promisor remote has to be already configured on the client side for
some of its config to be changed. In any case no new remote is
configured and no new URL is stored.

When a lock file is held, it can be helpful to know which process owns
it, especially when debugging stale locks left behind by crashed
processes. Add an optional feature that creates a companion PID file
alongside each lock file, containing the PID of the lock holder.
For a lock file "foo.lock", the PID file is named "foo~pid.lock". The
tilde character is forbidden in refnames and allowed in Windows
filenames, which guarantees no collision with the refs namespace
(e.g., refs "foo" and "foo~pid" cannot both exist). The file contains
a single line in the format "pid <value>" followed by a newline.
The PID file is created when a lock is acquired (if enabled), and
automatically cleaned up when the lock is released (via commit or
rollback). The file is registered as a tempfile so it gets cleaned up
by signal and atexit handlers if the process terminates abnormally.
When a lock conflict occurs, the code checks for an existing PID file
and, if found, uses kill(pid, 0) to determine if the process is still
running. This allows providing context-aware error messages:
Lock is held by process 12345. Wait for it to finish, or remove
the lock file to continue.
Or for a stale lock:
Lock was held by process 12345, which is no longer running.
Remove the stale lock file to continue.
The feature is controlled via core.lockfilePid configuration (boolean).
Defaults to false. When enabled, PID files are created for all lock
operations.
Existing PID files are always read when displaying lock errors,
regardless of the core.lockfilePid setting. This ensures helpful
diagnostics even when the feature was previously enabled and later
disabled.

Manually running
"git config submodule.<name>.gitdir .git/modules/<name>"
for each submodule can be impractical, so add a migration command to
submodule--helper to automatically create configs for all submodules
as required by extensions.submodulePathConfig.
The command calls create_default_gitdir_config() which validates the
gitdir paths before adding the configs.

Add a new config `init.defaultSubmodulePathConfig` which allows
enabling `extensions.submodulePathConfig` for new submodules by
default (those created via git init or clone).
Important: setting init.defaultSubmodulePathConfig = true does
not globally enable `extensions.submodulePathConfig`. Existing
repositories will still have the extension disabled and will
require migration (for example via git submodule--helper command
added in the next commit).

The idea of this extension is to abstract away the submodule gitdir
path implementation: everyone is expected to use the config and not
worry about how the path is computed internally, either in git or
other implementations.
With this extension enabled, the submodule.<name>.gitdir repo config
becomes the single source of truth for all submodule gitdir paths.
The submodule.<name>.gitdir config is added automatically for all new
submodules when this extension is enabled.
Git will throw an error if the extension is enabled and a config is
missing, advising users how to migrate. Migration is manual for now.
E.g. to add a missing config entry for an existing "foo" module:
git config submodule.foo.gitdir .git/modules/foo

Doc update.
* mh/doc-core-attributesfile:
docs: note the type of core.attributesfile
|
|
The previous wording:
> Path expansions are made the same way as for `core.excludesFile`.
required one to check the docs for 'core.excludesFile' and from there
the definition of the pathname variable type to understand the path
expansion behaviour of this variable. Instead, just link directly to the
pathname type.
This change is basically the same rewording as was done to
'core.excludesFile' in dca83abd (config: describe 'pathname' value
type, 2016-04-29).
