t5333: fix missing terminator for sed(1) 's' command
In 6aec8d38fdd (t: refactor tests depending on Perl to print data,
2025-04-03) we have changed some of the tests in t4150 to use sed(1)
instead of Perl. One of the conversions is broken though:
Curiously enough, the test itself still passes. This is caused by a
sequence of failures:
1. The output of sed(1) is piped into git-update-ref(1), and because
sed(1) is the upstream command we don't notice that it fails.
2. git-update-ref(1) does not receive any input and thus won't create
any references.
3. We then repack the repository with the configured pseudo merges
pattern, but as we didn't create any references the pattern doesn't
match anything.
4. We use `test_pseudo_merges()` to compute the list of pseudo-merges
and write it into a file. This file is empty as there are none.
5. The loop over the pseudo-merges becomes a no-op.
6. The final test succeeds as well because the number of lines in an
empty file is obviously the same as the number of unique lines,
namely zero.
Fix the issue by adding the terminating '|' to the sed(1) command.
Furthermore, make the test a tiny bit more robust by not using it as
part of a pipe.

build: fix FreeBSD build when sysinfo compat library installed
Commit 50dec7c566 ("config.mak.uname: add sysinfo() configuration for
cygwin", 2025-04-17) and later commit 187ce0222f ("configure.ac: upgrade
to a compilation check for sysinfo", 2025-05-19) added a 'sysinfo()'
check to the autoconf build.
The FreeBSD system has an optional sysinfo compatibility library, used
to assist in porting software, which causes the build to fail when it
is installed. The reason for the failure is the lack of '-lsysinfo'
during the linking step.
Several solutions were considered:
- add a 'linking' check to configure.ac in order to determine the
need to link a separate library (-lsysinfo). (This would require
a similar change to meson.build).
- change the order of the preprocessor conditionals in the total_ram()
function in 'builtin/gc.c', so that the *BSD sysctl() function
(in the HAVE_BSD_SYSCTL block) takes priority over the sysinfo()
function (in the HAVE_SYSINFO block).
- suppress the setting of HAVE_SYSINFO when HAVE_BSD_SYSCTL has been
defined (in both configure.ac and meson.build).
The first solution above, while simple, adds unnecessary code (the
sysinfo compat function is likely implemented using sysctl() anyway)
when git is happy to use sysctl() on *BSD systems.
The second solution would only be required by the autoconf and meson
build systems, the Makefile already sets the build variables to the
required values (since they are not 'auto-detected').
Here we opt for the final solution above, since it only requires that
we prioritise the 'auto-detected' build variables in the autoconf and
meson builds.
In order to fix the FreeBSD build, move the sysinfo() check after the
determination of the HAVE_BSD_SYSCTL build variable, suppressing the
setting of HAVE_SYSINFO if HAVE_BSD_SYSCTL is defined. Apply this logic
to both the configure.ac and meson.build file.

string-list: enable sign compare warnings check
In "add_entry", we call "get_entry_index" function to get the inserted
position. However, as the return type of "get_entry_index" function is
`int`, there is a sign compare warning when comparing the `index` with
the `list-nr` of unsigned type.
"get_entry_index" would always return unsigned index. However, the
current binary search algorithm initializes "left" to be "-1", which
necessitates the use of signed `int` return type.
The reason why we need to assign "left" to be "-1" is that in the
`while` loop, we increment "left" by 1 to determine whether the loop
should end. This design choice, while functional, forces us to use
signed arithmetic throughout the function.
To resolve this sign comparison issue, let's modify the binary search
algorithm with the following approach:
1. Initialize "left" to 0 instead of -1
2. Use `left < right` as the loop termination condition instead of
`left + 1 < right`
3. When searching the right part, set `left = middle + 1` instead of
`middle`

In the "apply only to files" mode (i.e., neither --index nor --cached
mode), the index should not be touched except to record intents to
add when --intent-to-add is on. Because having --intent-to-add on sets
update_index, to indicate that we may touch the index, we can't rely
only on that flag in create_file() (which is called to write both new
files and updated files) to decide whether to write an index entry;
if we did, we would write an index entry for every file being patched
(which would moreover be an intent-to-add entry despite not being a
new file, because we are going to turn on the CE_INTENT_TO_ADD flag
in add_index_entry() if we enter it here and ita_only is true).
To decide whether to touch the index, we need to check the
specific reason the index would be updated, rather than merely
their aggregate in the update_index flag. Because we have already
entered write_out_results() and are performing writes, we know that
state->apply is true. If state->check_index is additionally true, we
are in --index or --cached mode, which updates the index and should
always write, whereas if we are merely in ita_only mode we must only
write if the patch is a new file creation patch.

There are three main modes of operation for apply: applying only to the
worktree, applying to the worktree and index (--index), and applying
only to the index (--cached).
The --intent-to-add flag modifies the first of these modes, applying
only to the worktree, in a way which touches the index, because intents
to add are special index entries. However, since its introduction
in cff5dc09ed (apply: add --intent-to-add, 2018-05-26), it has not
worked correctly in any but the most trivial (empty repository)
cases, because the index is never read in (in apply, this is done in
read_apply_cache()) before writing to it.
This causes the operation to clobber the old, correct index with a
new empty-tree index before writing intent-to-add entries to this
empty index; the final result is that the index now records every
existing file in the repository as deleted, which is incorrect.
This error can be corrected by first reading the index. The
update_index flag is correctly set if ita_only is true, because this
flag causes the index to be updated. However, if we merely gate the
call to read_apply_cache() behind update_index, then it will not be
read when state->apply is false, even if it must be checked due to
being in --index or --cached mode. Therefore, we instead read the
index if it will be either checked or updated, because reading the
index is a prerequisite to either.

setup_revisions(): turn on diffs for all-negative diff filter
When the user gives us a diff filter like --diff-filter=D, we need to do
a tree diff even if we're not planning to show the diff result itself,
in order to decide whether to show the commit at all. So there's an
explicit check of revs->diffopt.filter in setup_revisions(), and we set
revs->diff if any bits are set.
Originally that "filter" field covered both positive capital-letter
filters (like "D") and also negative lowercase filters (like "d"), so it
was sufficient for both cases. But later, 75408ca949 (diff-filter: be
more careful when looking for negative bits, 2022-01-28) split the
negative bits out into a "filter_not" field.
We eventually fold those into "filter", but not until diff_setup_done()
is called, which happens after our explicit check. As a result, a purely
negative filter like:
git log --diff-filter=d
failed to turn on diffs at all. But rather than fail to filter by diff,
because the filter variable is eventually set, we mistakenly show no
commits at all, thinking that the empty diffs were cases where nothing
passed through the filter.
The smallest fix here is to just have our check look for any bits in
either "filter" or "filter_not". I suspect it would also be OK to
reorder the function a bit to call diff_setup_done() earlier, but that
risks violating some other subtle ordering dependency. So I went with
the simple and safe solution here.

comparatively small, which increases the risk that we miss critical

Address this by enabling the reftable format when experimental features

config.mak.uname: set NO_MEMMEM only for functional version
FreeBSD 6 introduced memmem(), but the implementation diverged
from what was standard everywhere else (including our "compat"
fallback).
FreeBSD 10.4 (went EOL in 2018) corrected the functionality bugs
but kept a suboptimal implementation until FreeBSD 11.4 (the last
version of FreeBSD 11, that went EOL in September 2021).
Let's draw the line to require FreeBSD 12 or newer, which allows us
to drop the special casing of FreeBSD 4.x and rely on the platform
implementation of memmem() unconditionally for all versions that are
still being supported.

The Makefile has a 'style' rule to run 'git clang-format'. While Meson
intrinsically supports a 'clang-format' target, which can be run when
using the ninja backend by running 'ninja clang-format', this runs the
formatting on all existing files.
Our Meson build doesn't yet support a way to run 'git clang-format',
which runs the formatter between the working directory and commit
provided. Add a new 'style' target to Meson to mimic the target in the
Makefile.

clang-format: add 'RemoveBracesLLVM' to the main config
In 1b8f306612 (ci/style-check: add `RemoveBracesLLVM` in CI job,
2024-07-23) we added 'RemoveBracesLLVM' to the CI job of running the
clang formatter.
This rule checks and warns against using braces on simple
single-statement bodies of statements. Since we haven't had any issues
regarding this rule, we can now move it into the main clang-format
config and remove it from being CI exclusive.

When clang-format was introduced to the Git project in 6134de6ac1 (clang-format: outline the git project's coding style,
2017-08-14), the 'ColumnLimit' was set to 80. This is inline with our
recommendation in 'Documentation/CodingGuidelines', which states:
We try to keep to at most 80 characters per line.
However while this is recommended limit, this is not the enforced
limit. In some cases in we do overflow this limit to prioritize
readability. Setting the 'ColumnLimit' also means that shorter lines are
concatenated to simply as the result would still be below 80 characters,
which is undesirable.
In the past, we tried to adjust the penalties around line wrapping, once
in 42efde4c29 (clang-format: adjust line break penalties, 2017-09-29)
and another time in 5e9fa0f9fa (clang-format: re-adjust line break
penalties, 2024-10-18). While these settings help tweak the line break
penalties to be more in-line with the requirements of the Git project,
using 'clang-format' still produces a lot of false positives.
So to make 'clang-format' more usable, set the 'ColumnLimit' to 0. This
means that line-wrapping is no-longer a concern of the formatter and
something that the user needs to take care of. The previous commit also
added a more flexible guideline to the '.editorconfig' setting a
'max_line_length' of 120 characters. This should provide some guidance
to users.
In the future, it would be nice to re-instate this limit with adequate
penalties which would follow our guidelines, but currently, it makes
more sense to have a working formatter which we can rely on and which
doesn't create too many false positives.

send-pack: clean-up even when taking an early exit
Previous commit has plugged one leak in the normal code path, but
there is an early exit that leaves without releasing any resources
acquired in the function.
This option was introduced in a series of commits from fe3ccc7aab (Merge
branch 'ps/config-subcommands', 2024-05-15) and deprecated

FreeBSD 13.4 is no longer supported, and 13.5 will be the last
release from that series, so jump instead to 14.3 which should
be supported for another 10 months and will be at that point
the oldest supported release with the interim release of 15.
While at it, move some variables to the environment and make
sure to skip a git grep test that assumes glibc regex.

daemon: correctly handle soft accept() errors in service_loop
Since df076bdbcc ([PATCH] GIT: Listen on IPv6 as well, if available.,
2005-07-23), the original error checking was included in an inner loop
unchanged, where its effect was different.
Instead of retrying, after a EINTR during accept() in the listening
socket, it will advance to the next one and try with that instead,
leaving the client waiting for another round.
Make sure to retry with the same listener socket that failed originally.
To avoid an unlikely busy loop, fallback to the old behaviour after a
couple of attempts.

In 9d2962a7c4 (receive-pack: use batched reference updates, 2025-05-19)
we updated the 'git-receive-pack(1)' command to use batched reference
updates. One edge case which was missed during this implementation was
when a user pushes multiple branches such as:
Before using batched updates, the references would be applied
sequentially and hence no conflicts would arise. With batched updates,
while the first update applies, the second fails due to D/F conflict. A
similar issue was present in 'git-fetch(1)' and was fixed by separating
out reference pruning into a separate transaction in the commit 'fetch:
use batched reference updates'. Apply a similar mechanism for
'git-receive-pack(1)' and separate out reference deletions into its own
batch.
This means 'git-receive-pack(1)' will now use up to two transactions,
whereas before using batched updates it would use _at least_ two
transactions. So using batched updates is still the better option.
Add a test to validate this behavior.

refs/files: skip updates with errors in batched updates
The commit 23fc8e4f61 (refs: implement batch reference update support,
2025-04-08) introduced support for batched reference updates. This
allows users to batch updates together, while allowing some of the
updates to fail.
Under the hood, batched updates use the reference transaction mechanism.
Each update which fails is marked as such. Any failed updates must be
skipped over in the rest of the code, as they wouldn't apply any more.
In two of the loops within 'files_transaction_finish()' of the files
backend, the failed updates aren't skipped over. This can cause a
SEGFAULT otherwise. Add the missing skips and a test to validate the
same.
