diff: stop output garbled message in dry run mode
|

Building a list using commit_list_insert_by_date() has quadratic worst
case complexity. Avoid it by just appending in the loop and sorting at
the end.
The number of merge bases is usually small, so don't expect speedups in
normal repositories. It has no limit, though. The added perf test
shows a nice improvement when dealing with 16384 merge bases:

The code to squelch output from "git diff -w --name-status"
etc. for paths that "git diff -w -p" would have stayed silent
leaked output from dry-run patch generation, which has been

Recently we attempted to improve "git diff -w" and friends to

In t7528 we spawn an SSH agent to verify that we can sign a commit via
it. This test has started to fail on some machines:
+++ ssh-agent
unix_listener_tmp: path "/home/pks/Development/git/build/test-output/trash directory.t7528-signed-commit-ssh/.ssh/agent/s.UTulegefEg.agent.UrPHumMXPq" too long for Unix domain socket
main: Couldn't prepare agent socket
As it turns out this is caused by a change in OpenSSH 10.1 [1]:
* ssh-agent(1), sshd(8): move agent listener sockets from /tmp to
under ~/.ssh/agent for both ssh-agent(1) and forwarded sockets
in sshd(8).
Instead of creating the socket in "/tmp", OpenSSH now creates the socket
in our home directory. And as the home directory gets modified to be
located in our test output directory we end up with paths that are
somewhat long. But Linux has a rather short limit of 108 characters for
socket paths, and other systems have even lower limits, so it is very
easy now to exceed the limit and run into the above error.
Work around the issue by using `ssh-agent -T`, which instructs it to
use the old behaviour and create the socket in "/tmp" again. This switch
has only been introduced with 10.1 though, so for older versions we have
to fall back to not using it. That's fine though, as older versions know
to put the socket into "/tmp" already.
An alternative approach would be to abbreviate the socket name itself so
that we create it as e.g. "sshsock" in the trash directory. But taking
the above example we'd still end up with a path that is 91 characters
long. So we wouldn't really have a lot of headroom, and it is quite
likely that some developers would see the issue on their machines.

In get_default_ssh_signing_key(), the default ssh signing key is
retrieved in `key_stdout` buf, which is then split using
strbuf_split_max() into up to two strbufs at a new line and the first
strbuf is returned as a `char *`and not a strbuf.
This makes the function lack the use of strbuf API as no edits are
performed on the split tokens.
Simplify the process of retrieving and returning the desired line by
using strchr() to isolate the line and xmemdupz() to return a copy of the
line. This removes the roundabout way of splitting the string into
strbufs, just to return the line.

In get_ssh_finger_print(), the output of the `ssh-keygen` command is
put into `fingerprint_stdout` strbuf. The string in `fingerprint_stdout`
is then split into up to 3 strbufs using strbuf_split_max(). However they
are not modified after the split thereby not making use of the strbuf API
as the fingerprint token is merely returned as a char * and not a strbuf.
Hence they do not need to be strbufs.
Simplify the process of retrieving and returning the desired token by
using strchr() to isolate the token and xmemdupz() to return a copy of the
token. This removes the roundabout way of splitting the string into
strbufs just to return the token.

Earlier, b55e6d36 (diff: ensure consistent diff behavior with
ignore options, 2025-08-08) introduced "dry-run" mode to the
diff machinery so that content-based diff filtering (like
ignoring space changes or those that match -I<regex>) can first
try to produce a patch without emitting any output to see if
under the given diff filtering condition we would get any output
lines, and a new helper function diff_flush_patch_quietly() was
introduced to use the mode to see an individual filepair needs
to be shown.
However, the solution was not complete. When files are deleted,
file modes change, or there are unmerged entries in the index,
dry-run mode still produces output because we overlooked these
conditions, and as a result, dry-run mode was not quiet.
To fix this, return early in emit_diff_symbol_from_struct() if
we are in dry-run mode. This function will be called by all the
emit functions to output the results. Returning early can avoid
diff output when files are deleted or file modes are changed.
Stop print message in dry-run mode if we have unmerged entries
in index. Discard output of external diff tool in dry-run mode.

As documented in git-bisect(1), `git bisect help` should display usage
information. However, since the migration of `git bisect` to a full
builtin command in 73fce29427 (Turn `git bisect` into a full built-in,
2022-11-10), this behavior was broken. Running `git bisect help` would,
instead of showing usage, either fail silently if already in a bisect
session, or otherwise trigger an interactive autostart prompt asking "Do
you want me to do it for you [Y/n]?".
Similarly, since df63421be9 (bisect--helper: handle states directly,
2022-11-10), running invalid subcommands like `git bisect foobar` also
led to the same behavior.
This occurred because `help` and other unrecognized subcommands were
being unconditionally passed to `bisect_state`, which then called
`bisect_autostart`, triggering the interactive prompt.
Fix this by:
1. Adding explicit handling for the `help` subcommand to show usage;
2. Validating that unrecognized commands are actually valid state
commands before calling `bisect_state`;
3. Showing an error with usage for truly invalid commands.
This ensures that `git bisect help` displays the usage as documented,
and invalid commands fail cleanly without entering interactive mode.
Alternate terms are still handled correctly through
`check_and_set_terms`.

The changed-path Bloom filters feature has proven stable and reliable
over several years of use, delivering significant performance
improvement for file history computation in large monorepos. Currently
a user can opt-in to writing the changed-path Bloom filters using the
"--changed-paths" option to "git commit-graph write". The filters will
be persisted until the user drops the filters using the
"--no-changed-paths" option. For this functionality, refer to 0087a87ba8
(commit-graph: persist existence of changed-paths, 2020-07-01).
Large monorepos using Git's background maintenance to build and update
commit-graph files could use an easy switch to enable this feature
without a foreground computation. In this commit, we're proposing a new
config option "commitGraph.changedPaths":
* If "true", "git commit-graph write" will write Bloom filters,
equivalent to passing "--changed-paths";
* If "false" or "unset", Bloom filters will be written during "git
commit-graph write" only if the filters already exist in the current
commit-graph file. This matches the default behaviour of "git
commit-graph write" without any "--[no-]changed-paths" option. Note
"false" can disable a previous "true" config value but doesn't imply
"--no-changed-paths".
This config will always respect the precedence of command line option
"--[no-]changed-paths".
We also set this new config as optional recommended config in scalar to
turn on this feature for large repos.

When using the structure subcommand for git-repo(1), evaluating a
repository may take some time depending on its shape. Add a progress
meter to provide feedback to the user about what is happening. The
progress meter is enabled by default when the command is executed from a

option.

All repository structure stats are outputted in a human-friendly table
form. This format is not suitable for machine parsing. Add a --format
option that supports three output modes: `table`, `keyvalue`, and `nul`.
The `table` mode is the default format and prints the same table output
as before.
With the `keyvalue` mode, each line of output contains a key-value pair
of a repository stat. The '=' character is used to delimit between keys
and values. The `nul` mode is similar to `keyvalue`, but key-values are
delimited by a NUL character instead of a newline. Also, instead of a
'=' character to delimit between keys and values, a newline character is
used. This allows stat values to support special characters without
having to cquote them. These two new modes provides output that is more
machine-friendly.

The amount of objects in a repository can provide insight regarding its
shape. To surface this information, use the path-walk API to count the
number of reachable objects in the repository by object type. All
regular references are used to determine the reachable set of objects.

The structure of a repository's history can have huge impacts on the
performance and health of the repository itself. Currently, Git lacks a
means to surface repository metrics regarding its structure/shape via a
single command. Acquiring this information requires users to be familiar
with the relevant data points and the various Git commands required to
surface them. To fill this gap, supplemental tools such as git-sizer(1)
have been developed.
To allow users to more readily identify repository structure related
information, introduce the "structure" subcommand in git-repo(1). The
goal of this subcommand is to eventually provide similar functionality
to git-sizer(1), but natively in Git.
The initial version of this command only iterates through all references
in the repository and tracks the count of branches, tags, remote refs,
and other reference types. The corresponding information is displayed in
a human-friendly table formatted in a very similar manner to
git-sizer(1). The width of each table column is adjusted automatically
to satisfy the requirements of the widest row contained.
Subsequent commits will surface additional relevant data points to
output and also provide other more machine-friendly output formats.

When an on-disk sparse index is expanded to a full one, it could be
due to some worktree state that requires looking at file entries
hidden within sparse tree entries. This can be avoided if the
worktree is cleaned up and some other issues related to the index
state are resolved.
Expand the advice message to include all of these cases, since 'git
sparse-checkout clean' is not currently capable of handling all
cases.
In the future, we may improve the behavior of 'git sparse-checkout
clean' to handle all of the cases.

On Windows, the MSYS layer translates absolute path names generated by
a shell script from the POSIX style /c/dir/file to the Windows style
C:/dir/file form that is understood by git.exe. This happens only when
the absolute path stands on its own as a program argument or a value of
an environment variable.
The earlier commits 749d6d166d (config: values of pathname type can be
prefixed with :(optional), 2025-09-28) and ccfcaf399f (parseopt: values
of pathname type can be prefixed with :(optional), 2025-09-28) added
test cases where ":(optional)" is inserted before an absolute path.
$PWD is used to construct the absolute paths, which gives the POSIX
form, and the result is ":(optional)/c/dir/template". Such command line
arguments are no longer recognized as absolute paths and do not undergo
translation.
Existing test cases that expect that the specified file does not exist
are not incorrect (after all, git.exe will not find /c/dir/template).
Yet, they are conceptually incorrect. That the use of $PWD is erroneous
is revealed by a test case that expects that the optional file exists.
Since no such test case is present, add one. Use "$(pwd)" to generate
the absolute paths, so that the command line arguments become
":(optional)C:/dir/template".

When running "git status -z --short", the marker on modified index
entries (e.g., "M") is colorized, but the "??" marker for untracked
entries is not. Let's fix the "??" entries to show color here.
At first glance you might think that neither should be colorized, as
usually one would use "-z" to get machine-readable output. But this is a
tricky and unusual case. We have two output formats, "--short" and
"--porcelain" which are substantially similar, but differ in that
"--short" is for humans who want something short and "--porcelain" is
for machines. And "-z" by itself, without any other output option, does
default to "--porcelain", so "git status -z" will not colorize anything.
But if you explicitly ask for "-z" and "--short" together, then that is
asking for the human-readable output, but separated by NULs. This is
unlikely to be useful directly, but could for example be used if the
output will be shown to a human outside of the terminal. At any rate,
the current behavior is clearly wrong (since we colorize some things but
not others), and I think colorizing everything is the least-surprising
thing we can do here.

In --quiet mode, since we produce only an exit code for "something was
changed" and no actual output, we can often get by with just a
tree-level diff. However, certain options require us to actually look at
the file contents (e.g., if we are ignoring whitespace changes). We have
a flag "diff_from_contents" for that, and if it is set we call
diff_flush() on each path.
To avoid producing any output (since we were asked to be --quiet), we
traditionally just redirected the output to /dev/null. That changed in
b55e6d36eb (diff: ensure consistent diff behavior with ignore options,
2025-08-08), which replaced that with a "dry_run" flag. In theory, with
dry_run set, we should produce no output. But it carries a risk of
regression: if we forget to respect dry_run in any of the output paths,
we'll accidentally produce output.
And indeed, there is at least one such regression in that commit, as it
covered only the case where we actually call into xdiff, and not
creation or deletion diffs, where we manually generate the headers. We
even test this case in t4035, but only with diff-tree, which does not
show the bug by default because it does not require diff_from_contents.
But git-diff does, because it allows external diff programs by default
(so we must dig into each diff filepair to decide if it requires running
an external diff that may declare two distinct blobs to actually be the
same).
We should fix all of those code paths to respect dry_run correctly, but
in the meantime we can protect ourselves more fully by restoring the
redirection to /dev/null. This gives us an extra layer of protection
against regressions dues to other code paths we've missed.
Though the original issue was reported with "git diff" (and due to its
default of --ext-diff), I've used "diff-tree -w" in the new test. It
triggers the same issue, but I think the fact that "-w" implies
diff_from_contents is a bit more obvious, and fits in with the rest of
t4035.

The Tags and Heads window always opens at a default position and size,
requiring users to reposition it each time. Remember its geometry
between sessions in the config file as `geometry(showrefs)`.
Note that the existing configuration is sourced in proc savestuff
right before new settings are written. This makes the old settings
available as local variables(!) and does not overwrite the current
settings. Since we need access to the global geometry(showrefs), it
is necessary to unset the local variable.

This reverts commit b9bee11526ec (gitk: Only restore window size from
~/.gitk, not position, 2008-03-10).
The earlier commit e9937d2a03a4 (Make gitk work reasonably well on
Cygwin, 2007-02-01) reworked the window layout considerably. Much of
this became irrelevant around 2011 after Cygwin gained an X11 server
and switched to a supportable port of the Unix/X11 Tcl/Tk (it is now
on the current 8.6 code base).
Part of the necessary change was to restore the window size across
sessions, but the position was also restored. This raised complaints
on the mailing list[*], because Gitk was opened on the wrong monitor.
b9bee11526ec was the compromise, because it was only the size that
mattered for the Cygwin layout engine to work.
I personally, find it annoying when Gitk pops up on a random location
on the screen, in particular, since many other applications restore
the window positions across sessions, so why not Gitk as well? (I do
not operate multi-monitor setups, so I cannot test the case.)

When using multiple threads in git-grep(1) we eagerly preload both the
gitmodules file as well as the packfiles so that the threads won't race
with one another to initialize these data structures.
For packfiles, this is done by calling `packfile_store_get_packs()`,
which first loads our packfiles and then returns a pointer to the first
such packfile. This pointer is ignored though, as all we really care
about is that `packfile_store_prepare()` was called.
Historically, that function was file-local to "packfile.c", but that
changed with 4188332569 (packfile: move `get_multi_pack_index()` into
"midx.c", 2025-09-02). We can thus simplify the code by calling that
function directly.

When running maintenance tasks via git-maintenance(1) we have a couple
of auto-conditions that check whether or not a specific task should be
running. One such check is for incremental repacks, which essentially
use `git multi-pack-index repack` to repack a set of smaller packfiles
into one larger packfile.
The auto-condition for this task checks how many packfiles there are
that aren't indexed by any multi-pack index. If there is a sufficient
number then we execute the above command to combine those into a single
pack and add that pack to the MIDX.
As we don't care about MIDX'd packs we use `packfile_store_get_packs()`,
which knows to not load any packs that are indexed by a MIDX. But as
explained in the preceding commit, we want to get rid of that function.
We already handle packfiles that have a MIDX by the very nature of this
function, as we explicitly count non-MIDX'd packs. As such, we can
trivially switch over to use `packfile_store_get_all_packs()` instead.
Do so.

When searching for abbreviated or when trying to disambiguate object IDs
we do this in two steps:
1. We search through the multi-pack index.
2. We search through all packfiles not part of any multi-pack index.
The second step uses `packfile_store_get_packs()`, which knows to skip
loading any packfiles that are indexed by an MIDX; this is exactly what
we want.
But that function is somewhat problematic, as its behaviour is stateful
and is influenced by `packfile_store_get_all_packs()`. This function
basically does the same as `packfile_store_get_packs()`, but in addition
it also loads all packfiles indexed by an MIDX. The problem here is that
both of these functions act on the same linked list of packfiles, and
thus depending on whether or not `get_all_packs()` was called the result
returned by `get_packs()` will be different. Consequently, all callers
of `get_packs()` need to be prepared to see MIDX'd packs even though
these should in theory be excluded.
This interface is confusing and thus potentially dangerous, which is why
we're converting all callers of `get_packs()` to use `get_all_packs()`
instead.
Do so for the above functions in "object-name.c". As explained, we
already know to skip any MIDX'd packs in both `find_abbrev_len_packed()`
and `find_short_packed_object()`, so it's fine to start loading MIDX'd
packfiles.

Commit 5040f9f164 ("doc: add technical design doc for large object
promisors", 2025-02-18) added the large object promisors document
as a technical document (with a '.txt' extension). The merge commit
2c6fd30198 ("Merge branch 'cc/lop-remote'", 2025-03-05) seems to
have renamed the file with an '.adoc' extension.
Despite the '.adoc' extension, this document was not being formatted
by asciidoc(tor) as part of the docs build. In order to do so, add
the document to the make and meson build files.
Having added the document to the build, asciidoc and asciidoctor find
(slightly different) problems with the syntax of the input document.
The first set of warnings (only issued by asciidoc) relate to some
'section title out of sequence: expected level 3, got level 4'. This
document uses 'setext' style of section headers, using a series of
underline characters, where the character used denotes the level of
the title. From document title to level 5 (see [1]), these characters
are =, -, ~, ^, +. This does not seem to fit the error message, which
implies that those characters denote levels 0 -> 4. Replacing the headings
underlined with '+' by the '^' character eliminates these warnings.
The second set of warnings (only issued by asciidoctor) relate to some
headings which seem to use both arabic and roman numerals as part of
a single 'list' sequence. This elicited either 'unterminated listing
block' or (for example) 'list item index: expected I, got II' warnings.
In order not to mix arabic and roman numerals, remove the numeral from
the '0) Non goals' heading. Similarly, the remaining roman numeral
entries had the ')' removed and turned into regular headings with I, II,
III ... at the beginning.

The formatting markup syntax used in this document (markdown?) is not
interpreted correctly by asciidoc or asciidoctor. The main problem is
the use of a '## ' prefix markup for some sub-headings, along with the
use of '```' code markup and some missing literal blocks.
In order to improve the (html) document formatting:
- replace the '## ' prefix sub-title syntax with the '~~' underlining
syntax for the relevant sub-headings.
- replace the '```' code markup, which causes asciidoc(tor) to simply
remove the marked up text, with a literal block '----' markup.
- the second ascii diagram, in the 'Merging commit-graph files'

and 1049. In asciidoc, numbered lists must start at one, whereas this

on line 17. (asciidoc only complains about the first instance of this,

545, 612, 752, 824, 895, 923 and 1053). These warnings stem from the
section titles not being correctly nested within a document/chapter
title.
In order to address the first set of warnings, simply renumber the list
from one to seven, rather than zero to six. Fortunately, this does not
require altering additional text, since the enumeration of 'Known Bugs'
is not referred to anywhere else in the document.
In order to address the second set of warnings, change the section title
syntax from '=== title ===' to '== title ==', effectively reducing the
nesting level of the title by one. Also, some apparent (sub-)titles are
not marked up with sub-title syntax, so add some '=== ' prefix(s) to the
relevant headings.
In addition to the warnings, address some other formatting issues:
- the use of heavily nested unordered lists is not reflected in the
output (making the file totally unreadable) because each level of
nesting requires a different syntax. (i.e. replace '*' with '**'
for the second level, '*' with '***' for the third level, etc.)
- make use of literal blocks and manual indentation to get asciidoc
and asciidoctor to display even remotely similar output.
- make use of labelled lists, in some places, to get a similar looking
output to the input, for both asciidoc and asciidoctor.
- replace the trailing space in: `git grep ${SEARCH_TERM} OLDREV `
otherwise the entire line in which that appears is removed from

Over the past several dozen commits, we have moved a large amount of
functionality out of the repack builtin and into other files like
repack.c, repack-cruft.c, repack-filtered.c, repack-midx.c, and
repack-promisor.c.
These files specify the minimal set of `#include`s that they need to
compile successfully, but we did not change the set of `#include`s in
the repack builtin itself.
Now that the code movement is complete, let's clean up that set of
`#include`s and trim down the builtin to include the minimal amount of
external headers necessary to compile.

The "pack_kept_objects" variable is defined as static to the repack
builtin, but is inherently related to the pack-objects arguments that
the builtin uses when generating new packs.
Move that field into the "struct pack_objects_args", and shuffle around
where we append the corresponding command-line option when preparing a
pack-objects process. Specifically:
- `write_cruft_pack()` always wants to pass "--honor-pack-keep", so
explicitly set the `pack_kept_objects` field to "0" when initializing
the `write_pack_opts` struct before calling `write_cruft_pack()`.
- `write_filtered_pack()` no longer needs to handle writing the
command-line option "--honor-pack-keep" when preparing a pack-objects
process, since its call to `prepare_pack_objects()` will have already
taken care of that.
`write_filtered_pack()` also reads the `pack_kept_objects` field to
determine whether to write the existing kept packs with a leading "^"
character, so update that to read through the `po_args` pointer
instead.
- `cmd_repack()` also no longer has to write the "--honor-pack-keep"
flag explicitly, since this is also handled via its call to
`prepare_pack_objects()`.
Since there is a default value for "pack_kept_objects" that relies on
whether or not we are writing a bitmap (and not writing a MIDX), extract
a default initializer for `struct pack_objects_args` that keeps this
conditional default behavior.

To prepare to move the `finish_pack_objects_cmd()` function out of the
builtin and into the repack.h API, there are a couple of things we need
to do first:
- First, let's take advantage of `write_pack_opts_is_local()` function
introduced in the previous commit instead of passing "local"
explicitly.
- Let's also avoid referring to the static 'packtmp' field within
builtin/repack.c by instead accessing it through the write_pack_opts
argument.
There are three callers which need to adjust themselves in order to
account for this change. The callers which reside in write_cruft_pack()
and write_filtered_pack() both already have an "opts" in scope, so they
can pass it through transparently.
The other call (at the bottom of `cmd_repack()`) needs to initialize its
own write_pack_opts to pass the necessary fields over to the direct call
to `finish_pack_objects_cmd()`.

Similar to the previous commit, the functions `write_cruft_pack()` and
`write_filtered_pack()` both compute a "local" variable via the exact
same mechanism:
const char *scratch;
int local = skip_prefix(opts->destination, opts->packdir, &scratch);
Not only does this cause us to repeat the same pair of lines, it also
introduces an unnecessary "scratch" variable that is common between both
functions.
Instead of repeating ourselves, let's extract that functionality into a
new function in the repack.h API called "write_pack_opts_is_local()".
That function takes a pointer to a "struct write_pack_opts" (which has
as fields both "destination" and "packdir"), and can encapsulate the
dangling "scratch" field.
Extract that function and make it visible within the repack.h API, and
use it within both `write_cruft_pack()` and `write_filtered_pack()`.
While we're at it, match our modern conventions by returning a "bool"
instead of "int", and use `starts_with()` instead of `skip_prefix()` to
avoid storing the dummy "scratch" variable.
The remaining duplication (that is, that both `write_cruft_pack()` and
`write_filtered_pack()` still both call `write_pack_opts_is_local()`)
will be addressed in the following commit.

Both callers within the repack builtin which call functions that take a
'write_pack_opts' structure have the following pattern:
struct write_pack_opts opts = {
.packdir = packdir,
.packtmp = packtmp,
.pack_prefix = find_pack_prefix(packdir, packtmp),
/* ... */
};
int ret = write_some_kind_of_pack(&opts, /* ... */);
, but both "packdir" and "packtmp" are fields within the write_pack_opts
struct itself!
Instead of also computing the pack_prefix ahead of time, let's have the
callees compute it themselves by moving `find_pack_prefix()` out of the
repack builtin, and have it take a write_pack_opts pointer instead of
the "packdir" and "packtmp" fields directly.
This avoids the callers having to do some prep work that is common
between the two of them, but also avoids the potential pitfall of
accidentally writing:
.pack_prefix = find_pack_prefix(packtmp, packdir),
(which is well-typed) when the caller meant to instead write:
.pack_prefix = find_pack_prefix(packdir, packtmp),

There are various functions within the 'repack' builtin which are
responsible for writing different kinds of packs. They include:
- `static int write_filtered_pack(...)`
- `static int write_cruft_pack(...)`
as well as the function `finish_pack_objects_cmd()`, which is
responsible for finalizing a new pack write, and recording the checksum
of its contents in the 'names' list.
Both of these `write_` functions have a few things in common. They both
take a pointer to the 'pack_objects_args' struct, as well as a pair of
character pointers for `destination` and `pack_prefix`.
Instead of repeating those arguments for each function, let's extract an
options struct called "write_pack_opts" which has these three parameters
as member fields. While we're at it, add fields for "packdir," and
"packtmp", both of which are static variables within the builtin, and
need to be read from within these two functions.
This will shorten the list of parameters that callers have to provide to
`write_filtered_pack()`, avoid ambiguity when passing multiple variables
of the same type, and provide a unified interface for the two functions
mentioned earlier.
(Note that "pack_prefix" can be derived on the fly as a function of
"packdir" and "packtmp", making it unnecessary to store "pack_prefix"
explicitly. This commit ignores that potential cleanup in the name of
doing as few things as possible, but a later commit will make that
change.)

To write a MIDX at the end of a repack operation, 'git repack' presently
computes the set of packs to write into the MIDX, before invoking
`write_midx_included_packs()` with a `string_list` containing those
packs.
The logic for computing which packs are supposed to appear in the
resulting MIDX is within `midx_included_packs()`, where it is aware of
details like which cruft pack(s) were written/combined, if/how we did a
geometric repack, etc.
Computing this list ourselves before providing it to the sole function
to make use of that list `write_midx_included_packs()` is somewhat
awkward. In the future, repack will learn how to write incremental
MIDXs, which will use a very different pack selection routine.
Instead of doing something like:
struct string_list included_packs = STRING_LIST_INIT_DUP;
if (incremental) {
midx_incremental_included_packs(&included_packs, ...):
write_midx_incremental_included_packs(&included_packs, ...);
} else {
midx_included_packs(&included_packs, ...):
write_midx_included_packs(&included_packs, ...);
}
in the future, let's have each function that writes a MIDX be
responsible for itself computing the list of included packs. Inline the
declaration and initialization of `included_packs` into the
`write_midx_included_packs()` function itself, and repeat that pattern
in the future when we introduce new ways to write MIDXs.

Besides reducing the number of parameters necessary to call the

`cmd_repack()`) oblivious to the set of packs being written into the

After writing a new MIDX, the repack command removes any bitmaps
belonging to packs which were written into the MIDX.
This is currently done in a separate function outside of
`write_midx_included_packs()`, which forces the caller to keep track of

Prepare to no longer require the caller to keep track of such

it into the existing_packs struct, further reducing the number of
parameters we have to pass around.
This amounts to adding a new string_list to the existing_packs struct,
and populating it via `existing_packs_collect()`. This is fairly
straightforward to do, since we are already looping over all packs, all
we need to do is:
if (p->multi_pack_index)
string_list_append(&existing->midx_packs, pack_basename(p));
Note, however, that this check *must* come before other conditions where
we discard and do not keep track of a pack, including the condition "if
(!p->pack_local)" immediately below. This is because the existing
routine which collects MIDX pack names does so blindly, and does not
discard, for example, non-local packs.

When writing a new MIDX, repack must determine whether or not there are
any packs in the MIDX it is replacing (if one exists) that are not
somehow represented in the new MIDX (e.g., either by preserving the pack
verbatim, or rolling it up as part of a geometric repack, etc.).
In order to do this, it keeps track of a list of pack names from the
MIDX present in the repository at the start of the repack operation.
Since we manipulate and close the object store, we cannot rely on the
repository's in-core representation of the MIDX, since this is subject
to change and/or go away.
When this behavior was introduced in 5ee86c273b (repack: exclude cruft
pack(s) from the MIDX where possible, 2025-06-23), we maintained an
array of character pointers instead of using a convenience API, such as
string-list.h.
Store the list of MIDX pack names in a string_list, thereby reducing the
number of parameters we have to pass to `midx_has_unknown_packs()`.

The function 'write_midx_included_packs()', which is responsible for
writing a new MIDX with a given set of included packs, currently takes a
list of six arguments.
In order to extract this function out of the builtin, we have to pass
in a few additional parameters, like 'midx_must_contain_cruft' and
'packdir', which are currently declared as static variables within the
builtin/repack.c compilation unit.
Instead of adding additional parameters to `write_midx_included_packs()`
extract out an "opts" struct that names these parameters, and pass a
pointer to that, making it less cumbersome to add additional parameters.

When writing a MIDX, 'git repack' takes a snapshot of the repository's
references and writes the result out to a file, which it then passes to
'git multi-pack-index write' via the '--refs-snapshot'.
This is done in order to make bitmap selections with respect to what we
are packing, thus avoiding a race where an incoming reference update
causes us to try and write a bitmap for a commit not present in the
MIDX.
Extract this functionality out into a new repack-midx.c compilation
unit, and expose the necessary functions via the repack.h API.

Once all new packs are known to exist, 'repack' installs their contents
from their temporary location into their permanent one. This is a
semi-involved procedure for each pack, since for each extension (e.g.,
".idx", ".pack", ".mtimes", and so on) we have to either:
- adjust the filemode of the temporary file before renaming it into
place, or
- die() if we are missing a non-optional extension, or
- unlink() any existing file for extensions that we did not generate
(e.g., if a non-cruft pack we generated was identical to, say, a
cruft pack which existed at the beginning of the process, we have to
remove the ".mtimes" file).
Extract this procedure into its own function, and call it
"generated_pack_install"(). This will set us up for pulling this
function out of the builtin entirely and making it part of the repack.h
API, which will be done in a future commit.

The repack builtin defines an API for keeping track of which packs
were found in the repository at the beginning of the repack operation.
This is used to classify what state a pack was in (kept, non-kept, or
cruft), and is also used to mark which packs to delete (or keep) at the
end of a repack operation.
Now that the prerequisite refactoring is complete, this API is isolated
enough that it can be moved out to repack.[ch] and removed from the
builtin entirely.
As a result, some of its functions become static within repack.c,
cleaning up the visible API.

There are a couple of spots that cause warnings within the
existing_packs API without DISABLE_SIGN_COMPARE_WARNINGS under
DEVELOPER=1 mode.
In both cases, we have int values that are being compared against size_t
ones. Neither of these two cases are incorrect, and the cast is
completely OK in practice. But both are unnecessary, since:
- in existing_packs_mark_for_deletion_1(), 'hexsz' should be defined as
a size_t anyway, since algop->hexsz is.
- in existing_packs_collect(), 'i' should be defined as a size_t since
it is counting up to the value of a string_list's 'nr' field.
(This patch is a little bit of noise, but I would rather see us squelch
these warnings ahead of moving the existing_packs API into a separate
compilation unit to avoid having to define DISABLE_SIGN_COMPARE_WARNINGS
in repack.c.)

The static variable 'delta_base_offset' determines whether or not we
pass the "--delta-base-offset" command-line argument when spawning
pack-objects as a child process. Its introduction dates back to when
repack was rewritten in C, all the way back in a1bbc6c017 (repack:
rewrite the shell script in C, 2013-09-15).
'struct pack_objects_args' was introduced much later on in 4571324b99
(builtin/repack.c: allow configuring cruft pack generation, 2022-05-20),
but did not move the 'delta_base_offset' variable.
Since the 'delta_base_offset' is a property of an individual
pack-objects command, re-introduce that variable as a member of 'struct

Over the years, builtin/repack.c has turned into a grab-bag of
functionality powering the 'git repack' builtin. Among its many
capabilities, it:
- can build and spawn 'git pack-objects' commands, which in turn
generate new packs
- has infrastructure to manage the set of existing packs in a
repository
- has infrastructure to split a sequence of packs into a geometric
progression based on object size
- can manage both generating and combining cruft packs together
- can write new MIDXs
to name a few.
As a result, this builtin has accumulated a lot of code, making adding
new functionality difficult. In the future, 'repack' will learn how to
manage a chain of incremental MIDXs, adding yet more functionality into
the builtin.
As a prerequisite step, let's first move some of the functionality in
the builtin into its own repack.[ch].
This will be done over the course of many steps, since there are many
individual components, some of which will end up in other, yet-to-exist
compilation units of their own. Some of the code movement here is also
non-trivial, so performing it in individual steps will make it easier to
verify.
Let's start by migrating 'struct pack_objects_args' (and the related
corresponding pack_objects_args_release() function) into repack.h, and
teach both the Makefile and Meson how to build the new compilation unit.

In previous commits, we started passing either repository or
git_hash_algo pointers around to various spots within builtin/repack.c
to reduce our dependency on the_repository in the hope of undef'ing
USE_THE_REPOSITORY_VARIABLE.
This commit takes us as far as we can (easily) go in that direction by
removing the only use of a convenience function that only exists when
USE_THE_REPOSITORY_VARIABLE is defined.
Unfortunately, the only other such function is "is_bare_repository()",
which is less than straightforward to convert into, say,
"repo_is_bare()", the latter of the two accepting a repository pointer.

The "files" backend has the ability to store symbolic refs as symbolic
links, which can be configured via "core.preferSymlinkRefs". This
feature stems back from the early days: the initial implementation of
symbolic refs used symlinks exclusively. The symref format was only
introduced in 9b143c6e15 (Teach update-ref about a symbolic ref stored
in a textfile., 2005-09-25) and made the default in 9f0bb90d16
(core.prefersymlinkrefs: use symlinks for .git/HEAD, 2006-05-02).
This is all about 20 years ago, and there are no known reasons nowadays
why one would want to use symlinks instead of symrefs. Mark the feature
for deprecation in Git 3.0.
Note that this only deprecates _writing_ symrefs as symbolic links.
Reading such symrefs is still supported for now.

The initial patch series that introduced Rust into the core of Git only
cared about macOS and Linux. This specifically leaves out Windows, which
indeed fails to build right now due to two issues:
- The Rust runtime requires `GetUserProfileDirectoryW()`, but we don't
link against "userenv.dll".
- The path of the Rust library built on Windows is different than on
most other systems systems.
Fix both of these issues to support Windows.
Note that this commit fixes the Meson-based job in GitHub's CI. Meson
auto-detects the availability of Rust, and as the Windows runner has
Rust installed by default it already enabled Rust support there. But due
to the above issues that job fails consistently.
Install Rust on GitLab CI, as well, to improve test coverage there.

In the current state of our Rust code base we don't really have any
requirements for the minimum supported Rust version yet, as we don't use
any features introduced by a recent version of Rust. Consequently, we
have decided that we want to aim for a rather old version and edition of
Rust, where the hope is that using an old version will make alternatives
like gccrs viable earlier for compiling Git.
But while we specify the Rust edition, we don't yet specify a Rust
version. And even if we did, the Rust version would only be enforced for
our own code, but not for any of our dependencies.
We don't yet have any dependencies at the current point in time. But
let's add some safeguards by specifying the minimum supported Rust
version and using cargo-msrv(1) to verify that this version can be
satisfied for all of our dependencies.
Note that we fix the version of cargo-msrv(1) at v0.18.1. This is the
latest release supported by Ubuntu's Rust version.

The `decode_varint()` and `encode_varint()` functions in our Rust crate
are reimplementations of the respective C functions. As such, we are
naturally forced to use the same interface in both Rust and C, which
makes use of raw pointers. The consequence is that the code needs to be
marked as unsafe in Rust.
It is common practice in Rust to provide safety documentation for every
block that is marked as unsafe. This common practice is also enforced by
Clippy, Rust's static analyser. We don't have Clippy wired up yet, and
we could of course just disable this check. But we're about to wire it
up, and it is reasonable to always enforce documentation for unsafe
blocks.
Add such safety comments to already squelch those warnings now. While at
it, also document the functions' behaviour.

Introduce a CI check that verifies that our Rust code is well-formatted.
This check uses `cargo fmt`, which is a wrapper around rustfmt(1) that
executes formatting for all Rust source files. rustfmt(1) itself is the
de-facto standard for formatting code in the Rust ecosystem.
The rustfmt(1) tool allows to tweak the final format in theory. In
practice though, the Rust ecosystem has aligned on style "editions".
These editions only exist to ensure that any potential changes to the
style don't cause reformats to existing code bases. Other than that,
most Rust projects out there accept this default style of a specific
edition.
Let's do the same and use that default style. It may not be anyone's
favorite, but it is consistent and by making it part of our CI we also
enforce it right from the start.
Note that we don't have to pick a specific style edition here, as the
edition is automatically derived from the edition we have specified in
our "Cargo.toml" file.
The implemented script looks somewhat weird as we perfom manual error
handling instead of using something like `set -e`. The intent here is
that subsequent commits will add more checks, and we want to execute all
of these checks regardless of whether or not a previous check failed.

When installing dependencies we first check for the distribution that is
in use and then we check for the specific job. In the first step we
already install all dependencies required to build and test Git, whereas
the second step installs a couple of additional dependencies that are
only required to perform job-specific tasks.
In both steps we use `apt-get update` to update our repository sources.
This is unnecessary though: all platforms that use Aptitude would have
already executed this command in the distro-specific step anyway.
Drop the redundant calls.

In b0b910e052 (cat-file.c: add batch handling for submodules,
2025-06-02), we began handling submodule entries specially when batching
cat-file like so:
$ echo :sha1collisiondetection | git.compile cat-file --batch-check
855827c583bc30645ba427885caa40c5b81764d2 submodule
Commit b0b910e052 notes that submodules are handled differently than
non-existent objects, which print "<given-name> <type>", since there is
(a) no object to resolve the OID of in the first place, and as commit
b0b910e052 notes, (b) for submodules in particular, it is useful to know
what commit it points at without having to spawn another Git process.
That commit does so by calling report_object_status() and passing in
"oid_to_hex(&data->oid)" for the "obj_name" parameter. This is
unnecessary, however, since report_object_status() will do the same
automatically if given a NULL "obj_name" argument.
That behavior dates back to 6a951937ae (cat-file: add
--batch-all-objects option, 2015-06-22), so rely on that instead of
having the caller open-code that part of report_object_status().

• Use backticks (`) for code-like things which will also use the correct

• Use inline-verbatim on options listing

option, 2025-09-17) added support for controlling how signed commits
are handled by `git fast-import`, but there is no option yet to

To remediate that, let's add a '--signed-tags=<mode>' option to

With this, both `git fast-export` and `git fast-import` have both
a '--signed-tags=<mode>' and a '--signed-commits=<mode>' supporting

Currently the handle_tag() function in "builtin/fast-export.c" searches
only for "\n-----BEGIN PGP SIGNATURE-----\n" in the tag message to find
a tag signature.
This doesn't handle all kinds of OpenPGP signatures as some can start
with "-----BEGIN PGP MESSAGE-----" too, and this doesn't handle SSH and
X.509 signatures either as they use "-----BEGIN SSH SIGNATURE-----" and
"-----BEGIN SIGNED MESSAGE-----" respectively.
To handle all these kinds of tag signatures supported by Git, let's use

In "t9350-fast-export.sh", these existing tests:
- 'fast-export | fast-import when main is tagged'
- 'cope with tagger-less tags'
are checking the number of annotated tags in the test repo by comparing
it with some hardcoded values.
This could be an issue if some new tests that have some prerequisites
add new annotated tags to the repo before these existing tests. When
the prerequisites would be satisfied, the number of annotated tags
would be different from when some prerequisites would not be satisfied.
As we are going to add new tests that add new annotated tags in a
following commit, let's properly count the number of annotated tag in
the repo by incrementing a counter each time a new annotated tag is
added, and then by comparing the number of annotated tags to the value
of the counter when checking the number of annotated tags.
This is a bit ugly, but it makes it explicit that some tests are
interdependent. Alternative solutions, like moving the new tests to
the end of the script, were considered, but were rejected because they
would instead hide the technical debt and could confuse developers in
the future.

When the 'GPG' prereq is lazily tested, `mkdir "$GNUPGHOME"` could
fail if the "$GNUPGHOME" directory already exists. This can happen if
the 'GPGSM' or the 'GPGSSH' prereq has been lazily tested before as they
already create "$GNUPGHOME".
To allow the GPGSM or the GPGSSH prereq to appear before the GPG prereq
in some test scripts, let's refactor the creation and setup of the
"$GNUPGHOME"` directory in a new prepare_gnupghome() function that uses
`mkdir -p "$GNUPGHOME"`.
This will be useful in a following commit.
Unfortunately the new prepare_gnupghome() function cannot be used when
lazily testing the GPG2 prereq, because that would expose existing,
hidden bugs in "t1016-compatObjectFormat.sh", so let's just document
that with a NEEDSWORK comment.

It looks like the documentation of `git tag` is focused a bit too
much on GPG signed tags.
This starts with the "NAME" section where the command is described
with:
"Create, list, delete or verify a tag object signed with GPG"
while for example `git branch` is described with simply:
"List, create, or delete branches"
This could give the false impression that `git tag` only works with
tag objects, not with lightweight tags, and that tag objects are
always GPG signed.
In the "DESCRIPTION" section, it looks like only "GnuPG signed tag
objects" can be created by the `-s` and `-u <key-id>` options, and it
seems `gpg.program` can only specify a "custom GnuPG binary".
This goes on in the "OPTIONS" section too, especially about the `-s`
and `-u <key-id>` options.
The "CONFIGURATION" section also doesn't talk about how to configure
the command to work with X.509 and SSH signatures.
Let's rework all that to make sure users have a more accurate and
balanced view of what the command can do.

is also that Ubuntu now defaults to sudo-rs(1).
