Like sha1_pack_name() that we dropped in the previous commit, this
function uses an error-prone static strbuf and the somewhat misleading
name "sha1".
The only caller left is in pack-redundant.c. While this command is
marked for potential removal in our BreakingChanges document, we still
have it for now. But it's simple enough to convert it to use its own
strbuf with the underlying odb_pack_name() function, letting us drop the
otherwise obsolete function.
Note that odb_pack_name() does its own strbuf_reset(), so it's safe to
use directly within a loop like this.

On Cygwin, t0301 fails because "git credential-cache exit" returns a
non-zero exit code. What's supposed to happen here is:
1. The client (the "credential-cache" invocation above) connects to a
previously-spawned credential-cache--daemon.
2. The client sends an "exit" command to the daemon.
3. The daemon unlinks the socket and then exits, closing the
descriptor back to the client.
4. The client sees EOF on the descriptor and exits successfully.
That works on most platforms, and even _used_ to work on Cygwin. But
that changed in Cygwin's ef95c03522 (Cygwin: select: Fix FD_CLOSE
handling, 2021-04-06). After that commit, the client sees a read error
with errno set to ECONNABORTED, and it reports the error and dies.
It's not entirely clear if this is a Cygwin bug. It seems that calling
fclose() on the filehandles pointing to the sockets is sufficient to
avoid this error return, even though exiting should in general look the
same from the client's perspective.
However, we can't just call fclose() here. It's important in step 3
above to unlink the socket before closing the descriptor to avoid the
race mentioned by 7d5e9c9849 (credential-cache--daemon: clarify "exit"
action semantics, 2016-03-18). The client will exit as soon as it sees
the descriptor close, and the daemon may or may not have actually
unlinked the socket by then. That makes test code like this:
git credential exit &&
test_path_is_missing .git-credential-cache
racy.
So we probably _could_ fix this by calling:
delete_tempfile(&socket_file);
fclose(in);
fclose(out);
before we exit(). Or by replacing the exit() with a return up the stack,
in which case the fclose() happens as we unwind. But in that case we'd
still need to call delete_tempfile() here to avoid the race.
But simpler still is that we can notice that we already special-case
ECONNRESET on the client side, courtesy of 1f180e5eb9 (credential-cache:
interpret an ECONNRESET as an EOF, 2017-07-27). We can just do the same
thing here (I suspect that prior to the Cygwin commit that introduced
this problem, we were really just seeing ECONNRESET instead of
ECONNABORTED, so the "new" problem is just the switch of the errno
values).

Whilst git-shortlog(1) does not explicitly need any repository
information when run without reference to one, it still parses some of
its arguments with parse_revision_opt() which assumes that the hash
algorithm is set. However, in c8aed5e8da (repository: stop setting SHA1
as the default object hash, 2024-05-07) we stopped setting up a default
hash algorithm and instead require commands to set it up explicitly.
This was done for most other commands like in ab274909d4 (builtin/diff:
explicitly set hash algo when there is no repo, 2024-05-07) but was
missed for builtin/shortlog, making git-shortlog(1) segfault outside of
a repository when given arguments like --author that trigger a call to
parse_revision_opt().
Fix this for now by explicitly setting the hash algorithm to SHA1. Also
add a regression test for the segfault.

2. the "*_block" suffix is more informative than "*_info", because it
describes a block (or region) of contiguous text which has trailers

The current code in run_builtin() passes in a repository to the builtin

This is incorrect, however, since some builtins that only have
RUN_SETUP_GENTLY can potentially take a repository.
setup_git_directory_gently() tells us whether or not a command is being

Use the output of setup_git_directory_gently() to help determine whether

just pass NULL.

It was reported on the mailing list that running `git maintenance start`
immediately segfaults starting with b6c3f8e12c (builtin/maintenance: fix
leak in `get_schedule_cmd()`, 2024-09-26). And indeed, this segfault is
trivial to reproduce up to a point where one is scratching their head
why we didn't catch this regression in our test suite.
The root cause of this error is `get_schedule_cmd()`, which does not
populate the `out` parameter in all cases anymore starting with the
mentioned commit. Callers do assume it to always be populated though and
will e.g. call `strvec_split()` on the returned value, which will of
course segfault when the variable is uninitialized.
So why didn't we catch this trivial regression? The reason is that our
tests always set up the "GIT_TEST_MAINT_SCHEDULER" environment variable
via "t/test-lib.sh", which allows us to override the scheduler command
with a custom one so that we don't accidentally modify the developer's
system. But the faulty code where we don't set the `out` parameter will
only get hit in case that environment variable is _not_ set, which is
never the case when executing our tests.
Fix the regression by again unconditionally allocating the value in the
`out` parameter, if provided. Add a test that unsets the environment
variable to catch future regressions in this area.

There's a racy hang in fsmonitor on macOS that we sometimes see in CI.
When we serve a client, what's supposed to happen is:
1. The client thread calls with_lock__wait_for_cookie() in which we
create a cookie file and then wait for a pthread_cond event
2. The filesystem event listener sees the cookie file creation, does
some internal book-keeping, and then triggers the pthread_cond.
But there's a problem: we start the listener that accepts client threads
before we start the fs event thread. So it's possible for us to accept a
client which creates the cookie file and starts waiting before the fs
event thread is initialized, and we miss those filesystem events
entirely. That leaves the client thread hanging forever.
In CI, the symptom is that t9210 (which is testing scalar, which always
enables fsmonitor under the hood) may hang forever in "scalar clone". It
is waiting on "git fetch" which is waiting on the fsmonitor daemon.
The race happens more frequently under load, but you can trigger it
predictably with a sleep like this, which delays the start of the fs
event thread:
--- a/compat/fsmonitor/fsm-listen-darwin.c
+++ b/compat/fsmonitor/fsm-listen-darwin.c
@@ -510,6 +510,7 @@ void fsm_listen__loop(struct fsmonitor_daemon_state *state)
FSEventStreamSetDispatchQueue(data->stream, data->dq);
data->stream_scheduled = 1;
+ sleep(1);
if (!FSEventStreamStart(data->stream)) {
error(_("Failed to start the FSEventStream"));
goto force_error_stop_without_loop;
One solution might be to reverse the order of initialization: start the
fs event thread before we start the thread listening for clients. But
the fsmonitor code explicitly does it in the opposite direction. The fs
event thread wants to refer to the ipc_server_data struct, so we need it
to be initialized first.
A further complication is that we need a signal from the fs event thread
that it is actually ready and listening. And those details happen within
backend-specific fsmonitor code, whereas the initialization is in the
shared code.
So instead, let's use the ipc_server init/start split added in the
previous commit. The generic fsmonitor code will init the ipc_server but
_not_ start it, leaving that to the backend specific code, which now
needs to call ipc_server_start_async() at the right time.
For macOS, that is right after we start the FSEventStream that you can
see in the diff above.
It's not clear to me if Windows suffers from the same problem (and we
simply don't trigger it in CI), or if it is immune. Regardless, the
obvious place to start accepting clients there is right after we've
established the ReadDirectoryChanges watch.
This makes the hangs go away in our macOS CI environment, even when
compiled with the sleep() above.

To start an async ipc server, you call ipc_server_run_async(). That
initializes the ipc_server_data object, and starts all of the threads
running, which may immediately start serving clients.
This can create some awkward timing problems, though. In the fsmonitor
daemon (the sole user of the simple-ipc system), we want to create the
ipc server early in the process, which means we may start serving
clients before the rest of the daemon is fully initialized.
To solve this, let's break run_async() into two parts: an initialization
which allocates all data and spawns the threads (without letting them
run), and a start function which actually lets them begin work. Since we
have two simple-ipc implementations, we have to handle this twice:
- in ipc-unix-socket.c, we have a central listener thread which hands
connections off to worker threads using a work_available mutex. We
can hold that mutex after init, and release it when we're ready to
start.
We do need an extra "started" flag so that we know whether the main
thread is holding the mutex or not (e.g., if we prematurely stop the
server, we want to make sure all of the worker threads are released
to hear about the shutdown).
- in ipc-win32.c, we don't have a central mutex. So we'll introduce a
new startup_barrier mutex, which we'll similarly hold until we're
ready to let the threads proceed.
We again need a "started" flag here to make sure that we release the
barrier mutex when shutting down, so that the sub-threads can
proceed to the finish.
I've renamed the run_async() function to init_async() to make sure we
catch all callers, since they'll now need to call the matching
start_async().
We could leave run_async() as a wrapper that does both, but there's not
much point. There are only two callers, one of which is fsmonitor, which
will want to actually do work between the two calls. And the other is
just a test-tool wrapper.
For now I've added the start_async() calls in fsmonitor where they would
otherwise have happened, so there should be no behavior change with this
patch.

Git currently stores absolute paths to both the main repository and
linked worktrees. However, this causes problems when moving repositories
or working in containerized environments where absolute paths differ
between systems. The worktree links break, and users are required to
manually execute `worktree repair` to repair them, leading to workflow
disruptions. Additionally, mapping repositories inside of containerized
environments renders the repository unusable inside the containers, and
this is not repairable as repairing the worktrees inside the containers
will result in them being broken outside the containers.
To address this, this patch makes Git always write relative paths when
linking worktrees. Relative paths increase the resilience of the
worktree links across various systems and environments, particularly
when the worktrees are self-contained inside the main repository (such
as when using a bare repository with worktrees). This improves
portability, workflow efficiency, and reduces overall breakages.
Although Git now writes relative paths, existing repositories with
absolute paths are still supported. There are no breaking changes
to workflows based on absolute paths, ensuring backward compatibility.
At a low level, the changes involve modifying functions in `worktree.c`
and `builtin/worktree.c` to use `relative_path()` when writing the
worktree’s `.git` file and the main repository’s `gitdir` reference.
Instead of hardcoding absolute paths, Git now computes the relative path
between the worktree and the repository, ensuring that these links are
portable. Locations where these respective file are read have also been
updated to properly handle both absolute and relative paths. Generally,
relative paths are always resolved into absolute paths before any
operations or comparisons are performed.
Additionally, `repair_worktrees_after_gitdir_move()` has been introduced
to address the case where both the `<worktree>/.git` and
`<repo>/worktrees/<id>/gitdir` links are broken after the gitdir is
moved (such as during a re-initialization). This function repairs both
sides of the worktree link using the old gitdir path to reestablish the
correct paths after a move.
The `worktree.path` struct member has also been updated to always store
the absolute path of a worktree. This ensures that worktree consumers
never have to worry about trying to resolve the absolute path themselves.

While the return parameter of `write_rev_file_order()` is a string
constant, the function may indeed return an allocated string when its
first parameter is a `NULL` pointer. This makes for a confusing calling
convention, where callers need to be aware of these intricate ownership
rules and cast away the constness to free the string in some cases.
Adapt the function and its caller `write_rev_file()` to always return an
allocated string and adapt callers to always free the return value.
Note that this requires us to also adapt `rename_tmp_packfile()`, which
compares the pointers to packfile data with each other. Now that the
path of the reverse index file gets allocated unconditionally the check
will always fail. This is fixed by using strcmp(3P) instead, which also

though, causing a memory leak. Plug it.

We're leaking the args vector in git-annotate(1) because we never clear
it. Fixing it isn't as easy as calling `strvec_clear()` though because
calling `cmd_blame()` will cause the underlying array to be modified.
Instead, we also need to pass a shallow copy of the argv array to the
function.
Do so to plug the memory leaks.

The `get_schedule_cmd()` function allows us to override the schedule
command with a specific test command such that we can verify the
underlying logic in a platform-independent way. Its memory management is
somewhat wild though, because it basically gives up and assigns an
allocated string to the string constant output pointer. While this part
is marked with `UNLEAK()` to mask this, we also leak the local string
lists.
Rework the function such that it has a separate out parameter. If set,
we will assign it the final allocated command. Plug the other memory
leaks and create a common exit path.

When parsing the maintenance strategy from config we allocate a config
string, but do not free it after parsing it. Plug this leak by instead
using `git_config_get_string_tmp()`, which does not allocate any memory.
This leak is exposed by t7900, but plugging it alone does not make the
test suite pass.
