On Windows, $(pwd) will give us a Windows-style path like "D:/foo".
Putting that into $PATH confuses anybody parsing that variable, since
colon is a separator character in $PATH. Instead, we should use the
Unix-style value we get from $PWD ("/d/foo").
This is similar to the cases fixed by 71dd50472d (t0021, t5615: use $PWD
instead of $(pwd) in PATH-like shell variables, 2016-11-11).

In 4e43b7ff (Declare both git-switch and git-restore experimental,
2019-04-25), the newly introduced git-switch(1) and git-restore(1)
commands were marked as experimental. This was done to provide time to
make breaking changes to the interface. It has now been over six years
since these commands were implemented and there hasn't been much change.
Consequently, users have grown to rely on how these commands work and it
is no longer feasible to make any breaking changes.
Let's remove the experimental label for git-switch(1) and
git-restore(1).

In the commit 51511d68f4 (for-each-ref: introduce a '--start-after'
option, 2025-07-15), for introducing the '--start-after' flag, the
`ref_iterator_seek()` was modified to also accept a flag. This was to
allow the function to also set the prefix when
'REF_ITERATOR_SEEK_SET_PREFIX' was set.
In `do_filter_refs()` instead of passing the flag, we pass in '1' which
is the value of the flag. While this works, this is definitely hard to
read and introduces inconsistency. Change it to use the flag.
While here, remove the unnecessary 'if (prefix)' clause in the 'else'
statement, since the block already checks for 'prefix'.

Improve the 'git-for-each-ref(1)' documentation with two corrections:
1. Add parentheses around `--exclude=<pattern>` to indicate this option
can be repeated as a complete unit.
2. Move `--stdin | <pattern> ...` to the end, after all flags, since
`<pattern>` is a positional argument that should appear last in the
argument list.
While here, change to using the synopsis block which will automatically
format placeholders in italics and keywords in monospace.

The commit 090eb5336c (refs: selectively set prefix in the seek
functions, 2025-07-15) modified the ref-cache iterator to support
seeking to a specified marker without setting the prefix.
The commit adds and uses an integer 'len' to capture the length of the
seek marker to compare with the entries of a given directory. Since the
type of the variable is 'int', this is met with a typecast of converting
a `strlen` to 'int' so it can be assigned to the 'len' variable.
This is whole operation is a bit wrong:
1. Since the 'len' variable is eventually used in a 'strncmp', it should
have been of type 'size_t'.
2. This also truncates the value provided from 'strlen' to an int, which
could cause a large refname to produce a negative number.
Let's do the correct thing here and simply use 'size_t' for `len`.

In 090eb5336c (refs: selectively set prefix in the seek functions,
2025-07-15) we separated the seeking functionality of reference
iterators from the functionality to set prefix to an iterator. This
allows users of ref iterators to seek to a particular reference to
provide pagination support.
The files-backend, uses the ref-cache iterator to iterate over loose
refs. The iterator tracks directories and entries already processed via
a stack of levels. Each level corresponds to a directory under the files
backend. New levels are added to the stack, and when all entries from a
level is yielded, the corresponding level is popped from the stack.
To accommodate seeking, we need to populate and traverse the levels to
stop the requested seek marker at the appropriate level and its entry
index. Each level also contains a 'prefix_state' which is used for
prefix matching, this allows the iterator to skip levels/entries which
don't match a prefix. The default value of 'prefix_state' is
PREFIX_CONTAINS_DIR, which yields all entries within a level. When
purely seeking without prefix matching, we want to yield all entries.
The commit however, skips setting the value explicitly. This causes the
MemorySanitizer to issue a 'use-of-uninitialized-value' error when
running 't/t6302-for-each-ref-filter'.
Set the value explicitly to avoid to fix the issue.

The old `lib-reftable.{c,h}` implemented helper functions for our
homegrown unit-testing framework. As part of migrating reftable-related
tests to the Clar framework, Clar-specific versions of these functions
in `lib-reftable-clar.{c,h}` were introduced.
Now that all test files using these helpers have been converted to Clar,
we can safely remove the original `lib-reftable.{c,h}` and rename the
Clar- specific versions back to `lib-reftable.{c,h}`. This restores a
clean and consistent naming scheme for shared test utilities.
Finally, update our build system to reflect the changes made and remove
redundant code related to the reftable tests and our old homegrown
unit-testing setup. `test-lib.{c,h}` remains unchanged in our build
system as some files particularly `t/helper/test-example-tap.c` depends
on it in order to run, and removing that would be beyond the scope of
this patch.

Helper functions defined in `t/unit-tests/lib-reftable.{c,h}` are
required for the reftable-related test files to run. In the current
implementation these functions are designed to conform with our
homegrown unit-testing structure. So in other to convert the reftable
test files, there is need for a clar specific implementation of these
helper functions.
Implement equivalent helper functions in `lib-reftable-clar.{c,h}` to
use clar. These functions conform with the clar testing framework and
become available for all reftable-related test files implemented using
the clar testing framework, which requires them. This will be used by
subsequent commits.

After we write to the output file, the program exits. This naturally
closes the descriptor. But we should do an explicit close for two
reasons:
1. It's possible to hit an error on close(), which we should detect
and report via our exit code.
2. Leaking descriptors is a bad practice in general. Even if it isn't
meaningful here, it sets a bad example.
It is tempting to write:
if (write_in_full(fd, ...) < 0 || close(fd) < 0)
die_errno(...);
But that pattern contains a subtle problem that has resulted in
descriptor leaks before. If write_in_full() fails, we'll short-circuit
and never call close(), leaking the descriptor.
That's not a problem here, since our error path dies instead of
returning up the stack. But since we're trying to set a good example,
let's write it out as two separate conditions. As a bonus, that lets us
produce a slightly more specific error message.

We want to read the whole contents of two files into memory. If we
switch from raw ptr/len pairs to strbufs, we can use strbuf_read_file()
to shorten the code.
This incidentally fixes two small bugs:
1. We stat() the files and allocate our buffers based on st.st_size.
But that is an off_t which may be larger than the size_t we'd use
to allocate. We should use xsize_t() to do a checked conversion.
Otherwise integer truncation (on a file >4GB) could cause us to
under-allocate (though in practice this does not result in a buffer
overflow because the same truncation happens when read_in_full()
also takes a size_t).
2. We get the size from st.st_size, and then try to read_in_full()
that many bytes. But it may return fewer bytes than expected (if
the file changed racily and we get an early EOF), leading us to
read uninitialized bytes in the allocated buffer. We don't notice
because we only check the value for error, not that we got the
expected number of bytes.
The strbuf code doesn't run into this, because it just reads to EOF,
expanding the buffer dynamically as necessary. Neither bug is a big deal
for a test helper, but fixing them is a nice bonus on top of simplifying
the code.

This is a short test helper that does all of its work in the main
function. When we encounter an error, we try to clean up memory and
descriptors and then jump to an error return, which exits the program.
We can get the same effect by just calling die(), which means we do not
have to bother with cleaning up. This simplifies the code, and also
removes some inconsistencies where a few code paths forgot to clean up
descriptors (though in practice it was not a big deal since we were
exiting anyway).
In addition to die() and die_errno(), we'll also use a few of our usual
helpers like xopen() and usage() that make things more ergonomic.
This does change the exit code in these cases from 1 to 128, but I
don't think it matters (and arguably is better, as we'd already exit 128
for other errors like xmalloc() failure).

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.

Optimize pop_most_recent_commit() by adding the first parent using the
more efficient prio_queue_peek() and prio_queue_replace() instead of
prio_queue_get() and prio_queue_put().
On my machine this neutralizes the performance hit it took in Git's own
repository when we converted it to prio_queue two patches ago (git_pq):
$ hyperfine -w3 -L git ./git_2.50.1,./git_pq,./git '{git} rev-parse :/^Initial.revision'

Add a function to replace the top element of the queue that basically
does the same as prio_queue_get() followed by prio_queue_put(), but
without the work by prio_queue_get() to rebalance the heap. It can be
used to optimize loops that get one element and then immediately add
another one. That's common e.g., with commit history traversal, where
we get out a commit and then put in its parents.

pop_most_recent_commit() calls commit_list_insert_by_date() for parent
commits, which is itself called in a loop. This can lead to quadratic
complexity if there are many merges. Replace the commit_list with a
prio_queue to ensure logarithmic worst case complexity and convert all
three users.
Add a performance test that exercises one of them using a pathological
history that consists of 50% merges and 50% root commits to demonstrate
the speedup:
Test v2.50.1 HEAD
----------------------------------------------------------------------
1501.2: rev-parse ':/65535' 2.48(2.47+0.00) 0.20(0.19+0.00) -91.9%
Alas, sane histories don't benefit from the conversion much, and
traversing Git's own history takes a 1% performance hit on my machine:

gitexec looks up and caches the method to execute git subcommands using
the long deprecated dashed form if found in $(git--exec-path). But,
git_read and git_write now use the dashless form, by-passing gitexec.
This leaves two remaining uses of gitexec: one during startup to define
use of an ssh_key helper, and one in the about dialog box. These are
neither performance critical nor likely to be called more than once, so
do not justify an otherwise unused cacheing system.
Let's change those two uses, making gitexec unused. This allows removing
gitexec and _git_cmd.

git-gui implements its own approach to locating and running various git
subcommands, bypassing git's capabilities for running git-*. This was
written in 2007: at that time, many git commands were shell-scripts
stored in $(git --exec-path), git's run-command api was not well adapted
to Windows and had serious performance issues when it worked at all, and
running subcommand 'git foo' as 'git-foo' was common and fully supported.
On Windows, git-gui searches $(git --exec-path) for builtin commands,
then attempts to find an interpreter on PATH to run those, invoking
these differently than on other platforms. For instance, the explicit
shebang #!/usr/bin/perl found in a script will be run by the first Perl
interpreter found on $PATH, which might not be at that specific location
so could be different than what git would run.
The various issues leading to the current implemention no longer exist.
Most git commands are now builtins, links to run those are not installed
in $(git --exec-path) by default (the "dashless" form is recommended
instead), and git's run-command api works well everywhere.
So, let's use git to launch its subcommands on all platforms. Do so by
modifying procs git_read and git_write to use the "dashless" form for
invoking git commands, avoiding the search for git-<foo>. This leaves
_git_cmd unused with cleanup in a later patch.

git-gui's default clone method is git-clone's default, and this uses
hardlinks rather than copying the objects directory for local
repositories. However, this method explicitly fails if a symlink (or
.gitfile) exists in the path to the objects directory. Thus, the default
clone option fails for worktrees created by git-new-workdir or
git-worktree. git-gui's original do_clone trapped this error for a
symlinked git-new-workdir tree, directly falling back to a full clone,
while the updated git-gui using git-clone does not. (The old do_clone
could not handle gitfile linked worktrees, however).
Let's apply the more friendly fallback to a full clone in both these
cases where git-clone behavior throws an error on the default method.

git-gui clones a repository by invoking git-plumbing commands, in proc
do_clone, rather than using git-clone. The justification was that the
low-level commands are guaranteed to provide a stable interface, while
the higher level commands such as git-clone may not be stable. This
approach requires git-gui to continually evolve by mirroring new
features in git itself, which has not happened, while the user interface
in git-clone has proven very stable. Also, git-gui does directly call
many other non-plumbing commands in git's repertoire.
do_clone's last significant functionality change was in 2015, and
updates are required for shallow clones, the reftable backend, cloning
from linked worktrees, and perhaps other features and bugs. For
instance, I had reports of git-gui failing to correctly clone
repositories prior to 2015, resulting in essentially the patch given
here. The only significant work was supporting .gitfile linked worktrees
unknown to do_clone, but supported by git-clone, and none regarding the
interface to git-clone itself. That interface is clearly stable enough
to not be a problem.
Supporting new use-cases with this requires exposing new options in the
clone dialog, then passing flags to git-clone. This avoids updating
do_clone to understand those options, reducing the maintenance burdens.
So, teach git-gui to use git-clone. This change is in one patch as
there is no obvious incremental path to migration. The existing dialog /
options / status screen are unchanged, the known user-visible changes
are that cloning from a working directory linked by a gitfile now works,
there is no auto-fallback to a full copy when cloning linked workdirs
and worktrees (meaning git-clone fails unless a full or shared copy is
selected), and messages displayed are from git-clone.

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`.

We added the --early-output feature long ago in cdcefbc971 (Add
"--early-output" log flag for interactive GUI use, 2007-11-03). The idea
was that GUIs could use it to progressively render a history view,
showing something quick-and-inaccurate at first and then enhancing it
later.
But we never documented it, and it appears never to have been used, even
by the projects which initially expressed interest. There was an RFC
patch for gitk to use it:
http://public-inbox.org/git/18221.2285.259487.655684@cargo.ozlabs.ibm.com/
but it was never merged. Likewise QGit had a patch in:
https://lore.kernel.org/git/e5bfff550711040225ne67c907r2023b1354c35f35@mail.gmail.com/
but it was never fully merged (to this day, QGit has a commented-out line to
add "--early-output" to the "log" invocation). Searching for other
mentions on the web or forges like github.com turns up nothing.
Meanwhile, the feature has been broken off and on over the years without
anybody noticing (and naturally, there are no tests, either). From 2011
to 2017 the option didn't even turn on via "--early-output"; this was
fixed in e35b6ac56f (revision.h: turn rev_info.early_output back into an
unsigned int, 2017-06-10).
It worked for a while then, but it does not interact well at all with
commit-graphs (which are turned on by default these days). The main
logic to count early commits is triggered by limit_list(), which we
traditionally invoked when showing output in topo-order (and
--early-output always enables --topo-order). But that changed in
f0d9cc4196 (revision.c: begin refactoring --topo-order logic,
2018-11-01). Now when we have generation numbers, we skip limit_list()
entirely, and the early-output code shows no commits, and just the final
header "Final output: 1 done". Which is syntactically OK, but
semantically wrong: that message should give the total number of commits
we're about to show.
So let's drop the feature. It is extra code that is untested and
undocumented, and makes working on the revision machinery more brittle.
Given the history above, it seems unlikely that anybody is using it (or
has used it), and we can drop it without the usual deprecation period.
A gentler option might be to "soft" drop it: keep accepting the option,
have it imply --topo-order as it does now, print "Final output: 1 done",
and then do our regular traversal. That would keep any hypothetical
caller working. But it doesn't seem worth the hassle to me.

git-gui requires that Tcl and Tk are 8.5, though the check using
'package require' allows 8.6. As git-gui runs under wish, both Tcl and
Tk are always available and of the same version, so only one need be
checked.
The 8.5 requirement is very outdated as the earliest Tcl currently
shipping on any supported OS is 8.6. 8.7 is in alpha test and is

git-gui since commit d6967022 explicitly requires version >= 1.5.0, and
this coded requirement has never been changed. But, since 0730a5a3a
git-gui actually requires git 2.36, providing 'git hook run.' git-gui
throws an error if that command is not supported.
So, let's update the requirement checking code to 2.36, and throw a more
useful error if this is not met.

gitk commit 5fdcbb1390 ("gitk: Fixes for Mac OS X TkAqua", 2009-03-23),
adds horizontal scrolling of the commit graph pane on aqua, but not on
x11 or win32. Also, the horizontal scrolling is triggered by MouseWheel
events attached to any of the three panes, not just the commit graph
that is the only one that scrolls. It is unusual to scroll a widget that
is not under the mouse, many would consider this a bug. No horizontal
scrollbar is provided for this, so there is no real cue for the user
that horizontal scrolling is available. We removed this aqua only
feature by transitioning aqua to use the common MouseWheel bindings set.
Let's add this as a feature on all platforms, and use the same approach
for scaling scroll motion as we do elsewhere. For horizontal scrolling,
honor only events received by the commit graph in conformance with
normal GUI design. Vertical scrolling is unchanged, and events received
by any of the 3 panes continue to scroll all 3 in unison.
Per the ancient and long ignored CUA standards, we should add a
horizontal scrollbar to the commit-graph, but gitk's interface is
already very cluttered: adding a scrollbar to only one of these three
panes is difficult while maintaining common pane vertical size,
especially so considering the movable sash separating panes 1 & 2, and
will consume yet more space. So, leave this as a hidden feature, now
available on all platforms.

Tk provides MouseWheel events to aqua, similar to win32. But, these
events on aqua have a nominal motion value (%D) of 1, not 120 as on
win32. gitk on aqua provides specific bindings only for the top 3 panes,
giving a nominal scrolling amount of +/- 1 for all events. gitk includes
a hidden feature providing horizontal scrolling of the commit graph,
added in 5fdcbb1390 ("gitk: Fixes for Mac OS X TkAqua", 2009-03-23).
This horizontal scrolling is triggered by mouse events in any of the top
3 panes, and thus violates normal gui design where the object under the
mouse cursor scrolls.
Let's update this using the common bindings in 'proc bind_mousewheel',
allowing user preferences on motion scaling to apply to all windows.
The commit graph scrolling feature is removed by this, and will be added
back for all platforms in a later commit.

gitk has x11 mouse bindings that receive button presses, not MouseWheel
events, as this is the Tk implementation through Tk 8.6. On x11, gitk
translates each button event to a scrolling value of +/- 5 for the upper
three panes that scroll vertically as one unit. gitk applies similar
scaling for horizontal scaling of the lower-left commit details pane
(ctext), but not for vertical scrolling of either of the bottom panes.
Rather, the Tk default scrolling actions are used for vertical
scrolling.
Let's make X11 behave similarly to the just modified win32 platform. Do
so by connecting vertical and horizontal scrolling events for the same
items bound in 'proc bind_mousewheel' and using the same user preference
values.

gitk on win32 binds windows_mousewheel_redirector to all MouseWheel
events in the main window. This proc determines the widget under the
cursor, then determines what scroll command to give, possibly none, and
issues scroll commands to the widget. The top panes get only vertical
scroll events, as does the lower right Patch/Tree pane. All others get
both vertical and horizontal events. These are all hard coded at +/-
five lines.
We now have common MouseWheel event bindings that follow user
preferences for the scrolling amount, bind for only the five main
display widgets, and leave the other gui elements untouched. Let's use
this instead. With the scrolling preference set at 5, the users should
not notice much, if any, difference.

gitk supports scrolling of 5 windows, but does this differently on the
aqua, x11, and win32 platforms as Tk provides different events on each.
TIP 171 removes some differences on win32 while altering the required
bindings on x11. TIP 474, which is in Tk 8.7 and later, finally unifies
all platforms on using common MouseWheel bindings. Importantly for now,
TIP 171 causes delivery of MouseWheel events to the widget under the
mouse cursor on win32, eliminating the need for completely different
bindings on win32.
Let's make some common functions to unify as much as we can in Tk 8.6.
Examining the platforms shows that the default platform scrolling is
overridden differently on the 3 platforms, and the nominal amount of
motion achieved per mouse wheel "click" is different. win32 nominally
makes everything move 5 lines per click, aqua 1 line per click, and x11
is a mixture. Part of this is due to win32 overriding all scroll events,
while x11 and aqua override smaller sets. Also, note that the text
widgets (the lower two panes) always scroll by 2-3 lines when given a
smaller scroll amount, while the upper three canvas objects follow the
requested scrolling value more accurately.
First, let's have a common routine to calculate the scroll value to give
to a widget in an event. This accounts for the user preference, the
scale of the %D (delta) value given by the event (120 on win32, 1 on
aqua, assumed 1 on x11), and must always be integer. Include negation as
by convention the screen moves opposite to the MouseWheel delta. Allow
setting an offset value to account for the larger minimum scrolling of
text widgets.
Second, let's have a common declaration of MouseWheel event bindings, as
those are shared by all in Tcl9, and by aqua/win32 earlier. Bind all
five display windows here. Note that the Patch/Tree widget (cflist)
cannot scroll horizontally.

gitk provides scrolling of several windows, uses hard-coded values for
the amount of scrolling, and these values differ across platforms and
widgets. The nominal value used is either 1 text line per mouse /
touchpad / button event, or 5 lines. Furthermore, Tk does not scroll
text widgets by 1 line when told to, this usually gets 2-3 lines of
motion. The upper canvas objects holding the commit graph do scroll as
defined. But, clearly no value is universally preferred, so let's give
the user some control over this. Provide a single multiplier to be
applied for all scroll bindings, with a value of 3 to mean the default
nominal value of 3 line. This is selected both as a compromise between
the various defaults across platforms, and because it is the smallest
value honored by the two text widgets on the bottom of the screen.
Later commits will connect this variable for actual scrolling events.

Tk through 8.6 has different approaches for handling mouse wheel /
touchpad scrolling events on the different platforms, and gitk has
separate code for these. But, some x11 bindings are applied on aqua as
we do not have these in a clean if / then / else tree based upon
platform. Let's split these bindings apart.

Using ttk had to be optional as Tk 8.4, then in common use, does not
have ttk. ttk is the default when available, so the ttk code paths are
by now very well tested. gitk also has code paths for the older default
widgets, increasing the maintenance burden. Let's make ttk non-optional

gitk includes many user defined configuration variables, has all of
these are listed in $config_variables. But this list is not used to
define the variables to be loaded, saved, or restored when cancelling
the configuration dialog, and developers must maintain separate lists of
variables for these purposes. This leads to unnecessary errors and merge
conflicts. Let's replace those separate lists with $config_variables to
make maintenance easier.
While we are on topic, sort the list of names in $config_variables.
This makes it simpler to scan and has fewer chances of conflicts

This patch adds the basic support of SHA256 Git repositories.
Most of changes are idiomatic replacement of the hard-coded hash ID
length, but there are subtle things:
* The hash length is determined on startup, and stored in $hashlength
global variable (either 40 or 64).
* The hard-coded "40" are replaced with $hashlength;
for regexp patterns, the ugly string map is used.
* Some code have the fixed numbers like 39 and 45, and those are
replaced with the $hashlength and the offset correction.
* $nullid and $nullid2 are generated for the hash length.
A caveat is that repository picker dialog is performed before
evaluating the repo type, hence $hashlength isn't set there yet.
So the code dealing with the hard-coded "40" are handled differently;
namely, the regexp range is expanded, and the null id is generated
from the HEAD id length locally.

If conflict comments already use a comment character that isn't "#", and
core.commentChar is set "auto", Git will ignore these lines during the
scan using ignored_log_message_bytes() and pick a new comment character
based on the rest of the message. The newly chosen character may be
different from the one used in the conflict comments and therefore,
these are no longer treated as comments and end up in the final commit
message.
For example, during a rebase if the user previously set
core.commentChar=% and then encounters a conflict, conflict comments
like "% Conflicts:" are generated. If the user subsequently sets
core.commentChar=auto before running `rebase --continue`, Git parses the
"auto" setting and begins scanning. It first uses the existing
'comment_line_str' (which is '%') to detect and ignore conflict comments
via ignored_log_message_bytes().
Then, Git scans the rest of the message (excluding conflict comments),
sees that none of the remaining lines start with '#' and decides to set
comment_line_str to '#'. Since the final commit character differs from
the one used in the conflict comments, those lines are no longer
considered comments and get included in the final commit message.
Set 'comment_line_str' to '#' when core.commentChar is set to 'auto' to
reset any previously set value.
While this does not solve the issue of conflict comment inclusion and
the user visible behaviour stays tha same, it standardizes the behaviour
of the code by always resetting 'comment_line_str' to '#' when
core.commentChar=auto is parsed.
The patch text is based on Phillip Wood's message:

When core.commentChar is set to "auto", Git selects a comment character
by scanning the commit message contents and avoiding any character
already present in the message.
If the message still contains old conflict comments (starting with a
comment character), Git assumes that character is in use and chooses a
different one. As a result, those existing comment lines are no longer
recognized as comments and end up being included in the final commit
message.
To avoid this, skip scanning the trailing comment block when selecting
the comment character. This allows Git to safely reuse the original
character when appropriate, keeping the commit message clean and free of
leftover conflict information.
Background:
The "auto" value for core.commentchar was introduced in the commit
84c9dc2c5a (commit: allow core.commentChar=auto for character auto
selection, 2014-05-17) but did not exhibit this issue at that time.
The bug was introduced in commit a6c2654f83 (rebase -m: fix --signoff
with conflicts, 2024-04-18) where Git started writing conflict comments
to the file at 'rebase_path_message()'.

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.

The compiler is in general able to recognize the endian shift and
replace it with an optimized opcode if possible. On certain
architectures such as RiscV or MIPS the situation can get complicated.
They don't provide an optimized opcode and masking the "higher" bits may
required loading a constant which needs shifting. This causes the
compiler to emit a lot of instructions for the operation.
The provided builtin directive on these architecture calls a function
which does the operation instead of emitting the code for operation.
Bring back the change from commit 6547d1c9 (bswap.h: add support for
built-in bswap functions, 2025-04-23). The bswap32/64 macro can now be
defined unconditionally so it won't regress on big endian architectures.

On x86 the bswap32/64 macro is implemented based on the x86 opcode which
performs the required shifting in just one opcode.
The other CPUs fallback to the generic shifting as implemented by
default_swab32() and default_bswap64() if needed.
I've been looking at how good a compiler is at recognizing the default
shift and emitting an optimized operation:
- x86, arm64 msvc v19.20
default_swab32() optimized
default_bswap64() shifts
_byteswap_uint64() optimized
- x86, arm64 msvc v19.37
default_swab32() optimized
default_bswap64() optimized
_byteswap_uint64() optimized
- arm64, gcc-4.9.4: optimized
- x86-64, gcc-4.4.7: shifts
- x86-64, gcc-4.5.3: optimized
- x86-64, clang-3.0: optimized
Given that gcc-4.5 and clang-3.0 are fairly old, any recent compiler
should recognize the shift.
Remove the optimized x86 version and rely on the compiler.

The ntohl and htonl macros are redefined because the provided macros were
not always optimal. Sometimes it was a function call, sometimes it was a
macro which did the shifting. Using the 'bswap' opcode on x86 provides
probably better performance than performing the shifting.
These macros are only overwritten on x86 if the "optimized" version is
available.
The ntohll and htonll macros are not available on every platform (at
least glibc does not provide them) which means they need to be defined
once the endianness of the system is determined.
In order to get a more symmetrical setup, redfine the macros once the
endianness of the system has been determined.

$GIT_TEST_INSTALLED can be set to use an "installed" git instead of the
one from $GIT_BUILD_DIR. This is used by my company's internal test
infrastructure, and not using $GIT_TEST_INSTALLED when querying the
default hash meant that the tests were failing because the hash was
effectively set to the empty string (since git didn't execute).
In the two places we attempt to detect/execute git itself prior to
overriding everything and putting it in $PATH, use identical logic for
identifying the git binary to execute. This also has the effect of
including the $X suffix when querying the default hash, but that's not
strictly necessary. You don't need to specify .exe when running a binary
on Windows, just when testing whether it exists or not.

As well as receiving the config key and value, config callbacks
also receive a "struct key_value_info" containing information about
the source of the key-value pair. Accessing the "path" field of
this struct from a callback passed to repo_config() results in a
use-after-free. This happens because repo_config() first populates a
configset by calling config_with_options() and then iterates over the
configset with the callback passed by the caller. When the configset
is constructed it takes a shallow copy of the "struct key_value_info"
for each config setting. This leads to the use-after-free as the
"path" member is freed before config_with_options() returns.
We could fix this by interning the "path" field as we do
for the "filename" field but the "path" field is not actually
needed. It is populated with a copy of the "path" field from "struct
config_source". That field was added in d14d42440d8 (config: disallow
relative include paths from blobs, 2014-02-19) to distinguish between
relative include directives in files and those in blobs. However,
since 1b8132d99d8 (i18n: config: unfold error messages marked for
translation, 2016-07-28) we can differentiate these by looking at the
"origin_type" field in "struct key_value_info". So let's remove the
"path" members from "struct config_source" and "struct key_value_info"
and instead use a combination of the "filename" and "origin_type"
fields to determine the absolute path of relative includes.

The function `get_multi_pack_index()` loads multi-pack indices via
`prepare_packed_git()` and then returns the linked list of multi-pack

Refactor `get_multi_pack_index()` so that it returns the multi-pack

When calling `close_midx()` we not only close the multi-pack index for
one object source, but instead we iterate through the whole linked list
of MIDXs to close all of them. This linked list is about to go away in
favor of using the new per-source pointer to its respective MIDX.
Refactor the function to iterate through sources instead.
Note that after this patch, there's a couple of callsites left that
continue to use `close_midx()` without iterating through all sources.
These are all cases where we don't care about the MIDX from other

In the preceding commit we refactored how we load multi-pack indices to
take a corresponding "source" as input. As part of this refactoring we
started to store a pointer to the MIDX in `struct odb_source` itself.
Refactor loading of packfiles in the same way: instead of passing in the
object directory, we now pass in the source from which we want to load
packfiles. This allows us to simplify the code because we don't have to
search for a corresponding MIDX anymore, but we can instead directly use
the MIDX that we have already prepared beforehand.

Multi-pack indices are tracked via `struct multi_pack_index`. This data
structure is stored as a linked list inside `struct object_database`,
which is the global database that spans across all of the object
sources.
This layout causes two problems:
- Object databases consist of multiple object sources (e.g. one source
per alternate object directory), where each multi-pack index is
specific to one of those sources. Regardless of that though, the
MIDX is not tracked per source, but tracked globally for the whole
object database. This creates a mismatch between the on-disk layout
and how things are organized in the object database subsystems and
makes some parts, like figuring out whether a source has an MIDX,
quite awkward.
- Multi-pack indices are an implementation detail of how efficient
access for packfiles work. As such, they are neither relevant in the
context of loose objects, nor in a potential future where we have
pluggable backends.
Refactor `prepare_multi_pack_index_one()` so that it works on a specific
source, which allows us to easily store a pointer to the multi-pack
index inside of it. For now, this pointer exists next to the existing
linked list we have in the object database. Users will be adjusted in
subsequent patches to instead use the per-source pointers.

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.

The ref iterator exposes a `ref_iterator_seek()` function. The name
suggests that this would seek the iterator to a specific reference in
some ways similar to how `fseek()` works for the filesystem.
However, the function actually sets the prefix for refs iteration. So
further iteration would only yield references which match the particular
prefix. This is a bit confusing.
Let's add a 'flags' field to the function, which when set with the
'REF_ITERATOR_SEEK_SET_PREFIX' flag, will set the prefix for the
iteration in-line with the existing behavior. Otherwise, the reference
backends will simply seek to the specified reference and clears any
previously set prefix. This allows users to start iteration from a
specific reference.
In the packed and reftable backend, since references are available in a
sorted list, the changes are simply setting the prefix if needed. The
changes on the files-backend are a little more involved, since the files
backend uses the 'ref-cache' mechanism. We move out the existing logic
within `cache_ref_iterator_seek()` to `cache_ref_iterator_set_prefix()`
which is called when the 'REF_ITERATOR_SEEK_SET_PREFIX' flag is set. We
then parse the provided seek string and set the required levels and
their indexes to ensure that seeking is possible.

The `ref_iterator` is an internal structure to the 'refs/'
sub-directory, which allows iteration over refs. All reference iteration
is built on top of these iterators.
External clients of the 'refs' subsystem use the various
'refs_for_each...()' functions to iterate over refs. However since these
are wrapper functions, each combination of functionality requires a new
wrapper function. This is not feasible as the functions pile up with the
increase in requirements. Expose the internal reference iterator, so
advanced users can mix and match options as needed.

To enable optimize multiple pathspec items in revision traversal,
return 0 if all pathspec item is literal in forbid_bloom_filters().
Add for loops to initialize and check each pathspec item's bloom_keyvec
when optimization is possible.
Add new test cases in t/t4216-log-bloom.sh to ensure
- consistent results between the optimization for multiple pathspec
items using bloom filter and the case without bloom filter
optimization.
- does not use bloom filter if any pathspec item is not literal.
With these optimizations, we get some improvements for multi-pathspec runs
of 'git log'. First, in the Git repository we see these modest results:
Benchmark 1: old
Time (mean ± σ): 73.1 ms ± 2.9 ms
Range (min … max): 69.9 ms … 84.5 ms 42 runs
Benchmark 2: new

'new' ran
1.33 ± 0.09 times faster than 'old'
But in a larger repo, such as the LLVM project repo below, we get even
better results:

Previously, we stored bloom keys in a flat array and marked a commit
as NOT TREESAME if any key reported "definitely not changed".
To support multiple pathspec items, we now require that for each
pathspec item, there exists a bloom key reporting "definitely not
changed".
This "for every" condition makes a flat array insufficient, so we
introduce a new structure to group keys by a single pathspec item.
`struct bloom_keyvec` is introduced to replace `struct bloom_key *`
and `bloom_key_nr`. And because we want to support multiple pathspec
items, we added a bloom_keyvec * and a bloom_keyvec_nr field to
`struct rev_info` to represent an array of bloom_keyvecs. This commit
still optimize only one pathspec item, thus bloom_keyvec_nr can only
be 0 or 1.
New bloom_keyvec_* functions are added to create and destroy a keyvec.
bloom_filter_contains_vec() is added to check if all key in keyvec is
contained in a bloom filter.

This patch adds a basic support of SHA256 Git repository to Gitk, so
that Gitk can show and operate on both SHA1 and SHA256 repos
gracefully. Since SHA256 has a longer ID length (64 char) than SHA1
(40 char), many field widths are adjusted to fit with it.
A caveat is that the configuration of auto selection length is shared
between SHA1 and SHA256 repos. That is, once when this value is saved
and read, it's applied to both repo types, which may result in shorter
selection than the full SHA256 ID. We may introduce another
individual config for sha256 (actually I did write in the first
version), but for simplicity, the common config is used as of writing
this.
Many lines still refer "sha1" although they may point to both SHA1 and
SHA256. They are left untouched for making the changes simpler.
This patch is based on the early work by Rostislav Krasny:
