Remove the duplicate option specs. These are primarily the explicit
'--no-' prefix opts which were added in f471494303 (git-send-email.perl:
support no- prefix with older GetOptions, 2015-01-30). This was done
specifically to support perl-5.8.0 which includes Getopt::Long 2.32[1].
Getopt::Long 2.33 added support for the '--no-' prefix natively by
appending '!' to the option specification string, which was included in
perl-5.8.1 and is not present in perl-5.8.0. The previous commit bumped
the minimum supported Perl version to 5.8.1 so we no longer need to
provide the '--no-' variants for negatable options manually.
Teach `--git-completion-helper` to output the '--no-' options. They are
not included in the options hash and would otherwise be lost.

fsck: use enum object_type for fsck_walk callback
We switched the function interface for fsck callbacks in a1aad71601
(fsck.h: use "enum object_type" instead of "int", 2021-03-28). However,
we accidentally flipped the type back to "int" as part of 0b4e9013f1
(fsck: mark unused parameters in various fsck callbacks, 2023-07-03).
The mistake happened because that commit was written before a1aad71601
and rebased forward, and I screwed up while resolving the conflict.
Curiously, the compiler does not warn about this mismatch, at least not
when using gcc and clang on Linux (nor in any of our CI environments).
Based on 28abf260a5 (builtin/fsck.c: don't conflate "int" and "enum" in
callback, 2021-06-01), I'd guess that this would cause the AIX xlc
compiler to complain. I noticed because clang-18's UBSan now identifies
mis-matched function calls at runtime, and does complain of this case
when running the test suite.
I'm not entirely clear on whether this mismatch is a problem in
practice. Compilers are certainly free to make enums smaller than "int"
if they don't need the bits, but I suspect that they have to promote
back to int for function calls (though I didn't dig in the standard, and
I won't be surprised if I'm simply wrong and the real-world impact would
depend on the ABI).
Regardless, switching it back to enum is obviously the right thing to do
here; the switch to "int" was simply a mistake.

t4053: avoid writing to unopened pipe
This fixes an occasional hang I see when running t4053 with
--verbose-log using dash.
Commit 1e3f26542a (diff --no-index: support reading from named pipes,
2023-07-05) added a test that "diff --no-index" will complain when
comparing a named pipe and a directory. The minimum we need to test this
is to mkfifo the pipe, and then run "git diff --no-index pipe some_dir".
But the test does one thing more: it spawns a background shell process
that opens the pipe for writing, like this:
{
(>pipe) &
} &&
This extra writer _could_ be useful if Git misbehaves and tries to open
the pipe for reading. Without the writer, Git would block indefinitely
and the test would never end. But since we do not have such a bug, Git
does not open the pipe and it is the writing process which will block
indefinitely, since there are no readers. The test addresses this by
running "kill $!" in a test_when_finished block. Since the writer should
be blocking forever, this kill command will reliably find it waiting.
However, this seems to be somewhat racy, in that the writing process
sometimes hangs around even after the "kill". In a normal run of the
test script without options, this doesn't have any effect; the
main test script completes anyway. But with --verbose-log, we spawn a
"tee" process that reads the script output, and it won't end until all
descriptors pointing to its input pipe are closed. And the background
process that is hanging around still has its stderr, etc, pointed into
that pipe.
You can reproduce the situation like this:
cd t
./t4053-diff-no-index.sh --verbose-log --stress
Let that run for a few minutes, and then you'll find that some of the
runs have hung. For example, at 11:53, I ran:
$ ps xk start o pid,start,command | grep tee | head
713459 11:48:06 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-9.out

and see that it's waiting to get EOF on its input:

It's a shell, presumably a subshell spawned by the main script. Though
it may seem odd, having the same descriptor open several times is not
unreasonable (they're all basically the original stdout/stderr of the
script that has been copied). And they should all close when the process
exits. So what's it doing? Curiously, it will exit as soon as we strace
it:
- it is blocking in the openat() call for the pipe, as we expect (so
this is definitely the backgrounded subshell mentioned above)
- strace sends signals (probably STOP/CONT); those cause the kernel to
stop blocking, but libc will restart the system call automatically
- by this time, the "pipe" fifo is gone, so we'll actually try to
create a regular file. But of course the surrounding directory is
gone, too! So we get ENOENT, and then exit as normal.
So the blocking is something we expect to happen. But what we didn't
expect is for the process to still exist at all! It should have been
killed earlier when the parent process called "kill", but it wasn't. And
we can't catch the race at this point, because it happened much earlier.
One can guess, though, that there is some race with the shell setting up
the signal handling in the backgrounded subshell, and possibly blocking
or ignoring signals at the time that the "kill" is received. Curiously,
the race does not seem to happen if I use "bash" instead of "dash", so
presumably bash's setup here is more atomic.
One fix might be to try killing the subshell more aggressively, either
using SIGKILL, or looping on kill/wait. But that seems complex and
likely to introduce new problems/races. Instead, we can observe that the
writer is not needed at all. Git will notice the pipe via stat() before
it is ever opened. So we can simply drop the writer subshell entirely.
If we ever changed Git to open the path and fstat() it, this would
result in the test hanging. But we're not likely to do that. After all,
we have to stat() paths to see if they are openable at all (e.g., it
could be a directory), so this seems like a low risk. And anybody who
does make such a change will immediately see the issue, as Git would
hang consistently.

t4053: avoid race when killing background processes
The test 'diff --no-index reads from pipes' starts a couple of
background processes that write to the pipes that are passed to "diff
--no-index". If the test passes then we expect these processes to exit
as all their output will have been read. However if the test fails
then we want to make sure they do not hang about on the users machine
and the test remembers they should be killed by calling
test_when_finished "! kill $!"
after each background process is created. Unfortunately there is a
race where test_when_finished may run before the background process
exits even when all its output has been read resulting in the kill
command succeeding which causes the test to fail. Fix this by ignoring
the exit status of the kill command. If the diff is successful we
could instead wait for the background process to exit and check their
status but that feels like it is testing the platform's printf
implementation rather than git's code.

mv: handle lstat() failure correctly
When moving a directory onto another with `git mv` various checks are

When calling `lstat` on the destination path and it fails as the path

`stat` memory nonetheless (I observed this issue on debian 12 of x86_64,
running on OrbStack on ARM, emulated with Rosetta).
This would affect the code that followed as it would still acccess a now
modified `st` structure, which now seems to contain uninitialized memory.
`S_ISDIR(st_dir_mode)` would then typically return false causing the code

We can fix it easily by free-ing the struct. We'll convert our "clear"
function to "free", since the allocation happens in the matching init()
function (though since there is only one call to each, and the struct is
local to this file, it's mostly academic).
Another option would be to put the struct on the stack rather than the
heap. However, this gets tricky, as we check the pointer against NULL in
several places to decide whether we're in geometric mode.

send-email: avoid creating more than one Term::ReadLine object
Every time git-send-email calls its ask() function to prompt the user,
we call term(), which instantiates a new Term::ReadLine object. But in
v1.46 of Term::ReadLine::Gnu (which provides the Term::ReadLine
interface on some platforms), its constructor refuses to create a second
instance[1]. So on systems with that version of the module, most
git-send-email instances will fail (as we usually prompt for both "to"
and "in-reply-to" unless the user provided them on the command line).
We can fix this by keeping a single instance variable and returning it
for each call to term(). In perl 5.10 and up, we could do that with a
"state" variable. But since we only require 5.008, we'll do it the
old-fashioned way, with a lexical "my" in its own scope.
Note that the tests in t9001 detect this problem as-is, since the
failure mode is for the program to die. But let's also beef up the
"Prompting works" test to check that it correctly handles multiple
inputs (if we had chosen to keep our FakeTerm hack in the previous

after the first).

send-email: drop FakeTerm hack
Back in 280242d1cc (send-email: do not barf when Term::ReadLine does not
like your terminal, 2006-07-02), we added a fallback for when
Term::ReadLine's constructor failed: we'd have a FakeTerm object
instead, which would then die if anybody actually tried to call
readline() on it. Since we instantiated the $term variable at program
startup, we needed this workaround to let the program run in modes when
we did not prompt the user.
But later, in f4dc9432fd (send-email: lazily load modules for a big
speedup, 2021-05-28), we started loading Term::ReadLine lazily only when
ask() is called. So at that point we know we're trying to prompt the
user, and we can just die if ReadLine instantiation fails, rather than
making this fake object to lazily delay showing the error.
This should be OK even if there is no tty (e.g., we're in a cron job),
because Term::ReadLine will return a stub object in that case whose "IN"
and "OUT" functions return undef. And since 5906f54e47 (send-email:
don't attempt to prompt if tty is closed, 2009-03-31), we check for that
case and skip prompting.
And we can be sure that FakeTerm was not kicking in for such a
situation, because it has actually been broken since that commit! It
does not define "IN" or "OUT" methods, so perl would barf with an error.
If FakeTerm was in use, we were neither honoring what 5906f54e47 tried
to do, nor producing the readable message that 280242d1cc intended.
So we're better off just dropping FakeTerm entirely, and letting the

The function is called indirectly via die_resolve_conflict() with fixed

curiosity. We do not have support for them to interoperate with
traditional SHA-1 repositories, but at this point, we do not plan
to make breaking changes to SHA-256 repositories and there is no
longer need for such a strongly phrased warning.

In at least some versions of clangd, including version 15 in Ubuntu
23.04, a directory, .cache, is written in the root of the repository
with index information about the files in the repository. Since clangd
is the most common language server protocol (LSP) implementation for C,
and we already support it using the GENERATE_COMPILATION_DATABASE flags
to make it functional, it's likely many users are using or will want to
use it.
As a result, ignore the ".cache" directory to help avoid users
accidentally committing the data.

docs: update when `git bisect visualize` uses `gitk`

since 5e1f28d (bisect--helper: reimplement `bisect_visualize()` shell
function in C, 2021-09-13) `git bisect visualize` uses exists_in_PATH()
to check wether it should call `gitk`, but exists_in_PATH() relies on
locate_in_PATH() which currently only understands POSIX-ish PATH variables
(a list of paths, separated by colons) on native Windows executables
we encounter Windows PATH variables (a list of paths that often contain
drive letters (and thus colons), separated by semicolons). Luckily we do
already have a function that can lookup executables on windows PATHs:
path_lookup(). Implement a small replacement for the existing
locate_in_PATH() based on path_lookup().

rebase --skip: fix commit message clean up when skipping squash
During a series of "fixup" and/or "squash" commands, the interactive
rebase accumulates a commit message from all the commits that are being
squashed together. If one of the commits has conflicts when it is picked
and the user chooses to skip that commit then we need to remove that
commit's message from accumulated messages. To do this 15ef69314d5
(rebase --skip: clean up commit message after a failed fixup/squash,
2018-04-27) updated commit_staged_changes() to reset the accumulated
message to the commit message of HEAD (which does not contain the
message from the skipped commit) when the last command was "fixup" or
"squash" and there are no staged changes. Unfortunately the code to do
this contains two bugs.
(1) If parse_head() fails we pass an invalid pointer to
unuse_commit_buffer().
(2) The reconstructed message uses the entire commit buffer from HEAD
including the headers, rather than just the commit message.
The first issue is fixed by splitting up the "if" condition into several
statements each with its own error handling. The second issue is fixed
by finding the start of the commit message within the commit buffer
using find_commit_subject().
The existing test added by 15ef69314d5 is modified to show the effect of
this bug. The bug is triggered when skipping the first command in the
chain (as the test does before this commit) but the effect is hidden
because opts->current_fixup_count is set to zero which leads
update_squash_messages() to recreate the squash message file from
scratch overwriting the bad message created by
commit_staged_changes(). The test is also updated to explicitly check
the commit messages rather than relying on grep to ensure they do not
contain any stray commit headers.
To check the commit message the function test_commit_message() is moved
from t3437-rebase-fixup-options.sh to test-lib.sh. As the function is
now publicly available it is updated to provide better error detection
and avoid overwriting the commonly used files "actual" and "expect".
Support for reading the expected commit message from stdin is also
added.

When we process a user's name (as in user.name), we strip all
leading and trailing crud from it. Right now, we consider a dot
a crud character, and strip it off.
However, this is unsuitable for many personal names because humans
frequently have abbreviated suffixes, such as "Jr." or "Sr." at the end
of their names, and this corrupts them. Some other users may wish to
use an abbreviated name or initial, which will pose a problem especially
in cultures that write the family name first, followed by the personal
name.
Since the current approach causes lots of practical problems, let's
avoid it by no longer considering a dot to be crud.
Note that "." in the name forces the entire name to be quoted to
please mailers, but stripping "." only at the beginning and the end
does not help a name with "." in the middle (like "brian m. carlson")
so this change will not make it much worse. A name like "Given
Family, Jr." that did not have to be quoted now would need to be, in
order to be placed on the e-mail headers, though.
This is based on a weather-balloon patch by Jeff King sent in Aug 2021
