Remove some complier warnings from msvc in compat/mingw.c for value
truncation from 64 bit to 32 bit integers.
Compiling compat/mingw.c under a 64 bit version of msvc produces
warnings. An "int" is 32 bit, and ssize_t or size_t should be 64 bit
long. Prepare compat/vcbuild/include/unistd.h to have a 64 bit type
_ssize_t, when _WIN64 is defined and 32 bit otherwise.
Further down in this include file, as before, ssize_t is defined as
_ssize_t, if needed.
Use size_t instead of int for all variables that hold the result of
strlen() or wcslen() (which cannot be negative).
Use ssize_t to hold the return value of read().

On macOS, fsmonitor can fall into a race condition that results in
a client waiting forever to be notified for an event that have
already happened. This problem has been corrected.

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.

In "environment.h" we have quite a lot of functions and variables that
either explicitly or implicitly depend on `the_repository`.
The implicit set of stateful declarations includes for example variables
which get populated when parsing a repository's Git configuration. This
set of variables is broken by design, as their state often depends on
the last repository config that has been parsed. So they may or may not
represent the state of `the_repository`.
Fixing that is quite a big undertaking, and later patches in this series
will demonstrate a solution for a first small set of those variables. So
for now, let's guard these with `USE_THE_REPOSITORY_VARIABLE` so that
callers are aware of the implicit dependency.

If neither HAVE_DEV_TTY nor GIT_WINDOWS_NATIVE is set, the fallback

But we still have to keep the unused parameter, since our interface

As with the files touched in the previous commit, win32/headless.c does
not include git-compat-util.h, so it doesn't have our UNUSED macro.
Unlike those ones, this is not third-party code, so it would not be a
big deal to modify it.
However, I'm not sure if including git-compat-util.h would create other
headaches (and I don't even have a machine to test this on; I'm relying
on Windows CI to compile it at all). Given how trivial the file is, and
that the unused parameters are not interesting (they are just
boilerplate for the wWinMain() function), we can just use the same trick
as the previous commit and disable the warnings via pragma.

We carry some vendored 3rd-party code in compat/ that does not build
cleanly with -Wunused-parameters. We could mark these with UNUSED, but
there are two reasons not to:
1. This is code imported from elsewhere, so we'd prefer to avoid
modifying it in an invasive way that could create conflicts if we
tried to pull in a new version.
2. These files don't include git-compat-util.h at all, so we'd need to
factor out (or repeat) our UNUSED macro.
In theory we could modify the build process to invoke the compiler with
the extra warning disabled for these files, but there are tricky corner
cases there (e.g., for NO_REGEX we cannot assume that the compiler
understands -Wno-unused-parameter as an option, so we'd have to use our
detect-compiler script).
Instead, let's rely on the gcc diagnostic #pragma. This is horribly
unportable, of course, but it should do what we want. Compilers which
don't understand this particular pragma should ignore it (per the
standard), and compilers which do care about "-Wunused-parameter" will
hopefully respect it, even if they are not gcc (e.g., clang does).

Whether the full path to the MSYS2 Bash is specified using backslashes
or forward slashes, in either case the command-line arguments need to be
quoted in the MSYS2-specific manner instead of using regular Win32
command-line quoting rules.
In preparation for `prepare_shell_cmd()` to use the full path to
`sh.exe` (with forward slashes for consistency), let's teach the
`is_msys2_sh()` function about this; Otherwise 5580.4 'clone with
backslashed path' would fail once `prepare_shell_cmd()` uses the full
path instead of merely `sh`.
This patch relies on the just-introduced fix where `fspathcmp()` handles
backslashes and forward slashes as equivalent on Windows.

On Windows, the backslash is the directory separator, even if the
forward slash can be used, too, at least since Windows NT.
This means that the paths `a/b` and `a\b` are equivalent, and
`fspathcmp()` needs to be made aware of that fact.
Note that we have to override both `fspathcmp()` and `fspathncmp()`, and
the former cannot be a mere pre-processor constant that transforms calls
to `fspathcmp(a, b)` into `fspathncmp(a, b, (size_t)-1)` because the
function `report_collided_checkout()` in `unpack-trees.c` wants to
assign `list.cmp = fspathcmp`.
Also note that `fspatheq()` does _not_ need to be overridden because it
calls `fspathcmp()` internally.

The IPC socket used by the fsmonitor on Darwin is usually contained in
the Git repository itself. When the repository is hosted on a networked
filesystem though, we instead create the socket path in the user's home
directory or the socket directory. In that case, we derive the path by
hashing the repository path.
But while we always use SHA1 to hash the repository path, we then end up
using `hash_to_hex()` to append the computed hash to the socket path.
This is wrong because `hash_to_hex()` uses the hash algorithm configured
in `the_repository`, which may not be SHA1. The consequence is that we
may append uninitialized bytes to the path when operating in a SHA256
repository.
Fix this bug by using `hash_to_hex_algop()` with SHA1.

Use of the `the_repository` variable is deprecated nowadays, and we
slowly but steadily convert the codebase to not use it anymore. Instead,
callers should be passing down the repository to work on via parameters.
It is hard though to prove that a given code unit does not use this
variable anymore. The most trivial case, merely demonstrating that there
is no direct use of `the_repository`, is already a bit of a pain during
code reviews as the reviewer needs to manually verify claims made by the
patch author. The bigger problem though is that we have many interfaces
that implicitly rely on `the_repository`.
Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code
units to opt into usage of `the_repository`. The intent of this macro is
to demonstrate that a certain code unit does not use this variable
anymore, and to keep it from new dependencies on it in future changes,
be it explicit or implicit
For now, the macro only guards `the_repository` itself as well as
`the_hash_algo`. There are many more known interfaces where we have an
implicit dependency on `the_repository`, but those are not guarded at
the current point in time. Over time though, we should start to add
guards as required (or even better, just remove them).
Define the macro as required in our code units. As expected, most of our
code still relies on the global variable. Nearly all of our builtins
rely on the variable as there is no way yet to pass `the_repository` to
their entry point. For now, declare the macro in "biultin.h" to keep the
required changes at least a little bit more contained.

Update to the code that writes to pipes on Windows.
* js/win32-retry-pipe-write-on-enospc:
win32: special-case `ENOSPC` when writing to a pipe
|
|
Since c6d3cce6f3c4 (pipe_command(): handle ENOSPC when writing to a
pipe, 2022-08-17), one `write()` call that results in an `errno` value
`ENOSPC` (which typically indicates out of disk space, which makes
little sense in the context of a pipe) is treated the same as `EAGAIN`.
However, contrary to expectations, as diagnosed in
https://github.com/python/cpython/issues/101881#issuecomment-1428667015,
when writing to a non-blocking pipe on Windows, an `errno` value of
`ENOSPC` means something else: the write _fails_. Completely. Because
more data was provided than the internal pipe buffer can handle.
Somewhat surprising, considering that `write()` is allowed to write less
than the specified amount, e.g. by writing only as much as fits in that
buffer. But it doesn't, it writes no byte at all in that instance.
Let's handle this by manually detecting when an `ENOSPC` indicates that
a pipe's buffer is smaller than what needs to be written, and re-try
using the pipe's buffer size as `size` parameter.
It would be plausible to try writing the entire buffer in a loop,
feeding pipe buffer-sized chunks, but experiments show that trying to
write more than one buffer-sized chunk right after that will immediately
fail because the buffer is unlikely to be drained as fast as `write()`
could write again. And the whole point of a non-blocking pipe is to be
non-blocking.
Which means that the logic that determines the pipe's buffer size
unfortunately has to be run potentially many times when writing large
amounts of data to a non-blocking pipe, as there is no elegant way to
cache that information between `write()` calls. It's the best we can do,
though, so it has to be good enough.
This fix is required to let t3701.60 (handle very large filtered diff)
pass with the MSYS2 runtime provided by the MSYS2 project: Without this
patch, the failed write would result in an infinite loop. This patch is
not required with Git for Windows' variant of the MSYS2 runtime only
because Git for Windows added an ugly work-around specifically to avoid
a hang in that test case.
The diff is slightly chatty because it extends an already-existing
conditional that special-cases a _different_ `errno` value for pipes,
and because this patch needs to account for the fact that
`_get_osfhandle()` potentially overwrites `errno`.

The unnecessary include in the header transitively pulled in some
other headers actually needed by source files, though. Have those
source files explicitly include the headers they need.

When the config parser sees an "implicit" bool like:
[core]
someVariable
it passes NULL to the config callback. Any callback code which expects a
string must check for NULL. This usually happens via helpers like
git_config_string(), etc, but some custom code forgets to do so and will
segfault.
These are all fairly vanilla cases where the solution is just the usual
pattern of:
if (!value)
return config_error_nonbool(var);
though note that in a few cases we have to split initializers like:
int some_var = initializer();
into:
int some_var;
if (!value)
return config_error_nonbool(var);
some_var = initializer();
There are still some broken instances after this patch, which I'll
address on their own in individual patches after this one.

Unused parameters in fsmonitor related code paths have been marked
as such.
* jk/fsmonitor-unused-parameter:
run-command: mark unused parameters in start_bg_wait callbacks
fsmonitor: mark unused hashmap callback parameters
fsmonitor/darwin: mark unused parameters in system callback
fsmonitor: mark unused parameters in stub functions
fsmonitor/win32: mark unused parameter in fsm_os__incompatible()
fsmonitor: mark some maybe-unused parameters
fsmonitor/win32: drop unused parameters
fsmonitor: prefer repo_git_path() to git_pathdup()

We pass fsevent_callback() to the system FSEventStreamCreate() function
as a callback. So we must match the expected function signature, even
though we don't care about all of the parameters. Mark the unused ones
to satisfy -Wunused-parameter.

The fsmonitor code has some platform-specific functions for which one or
more platforms implement noop or stub functions. We can't get rid of
these functions nor change their interface, since the point is to match
their equivalents in other platforms. But let's annotate their
parameters to quiet the compiler's -Wunused-parameter warning.

We never look at the "ipc" argument we receive. It was added in
8f44976882 (fsmonitor: avoid socket location check if using hook,
2022-10-04) to support the darwin fsmonitor code. The win32 code has to
match the same interface, but we should use an annotation to silence
-Wunused-parameter.

A few helper functions (centered around file-watch events) take extra
fsmonitor state parameters that they don't use. These are static helpers
local to the win32 implementation, and don't need to conform to any
particular interface. We can just drop the extra parameters, which
simplifies the code and silences -Wunused-parameter.

The fsmonitor_ipc__get_path() function ignores its repository argument.
It should use it when constructing repo paths (though in practice, it is
unlikely anything but the_repository is ever passed, so this is cleanup
and future proofing, not a bug fix).
Note that despite the lack of "dup" in the name, repo_git_path() behaves
like git_pathdup() and returns an allocated string.

We prefer for callback functions to match the signature with which
they'll be called, rather than casting them to the correct type when
assigning function pointers. Even though casting often works in the real
world, it is a violation of the standard.
We did a mass conversion in 939af16eac (hashmap_cmp_fn takes
hashmap_entry params, 2019-10-06), but have grown a few new cases since
then. Because of the cast, the compiler does not complain. However, as
of clang-18, UBSan will catch these at run-time, and the case in
range-diff.c triggers when running t3206.
After seeing that one, I scanned the results of:
git grep '_fn)[^(]' '*.c' | grep -v typedef
and found a similar case in compat/terminal.c (which presumably isn't
called in the test suite, since it doesn't trigger UBSan). There might
be other cases lurking if the cast is done using a typedef that doesn't
end in "_fn", but loosening it finds too many false positives. I also
looked for:
git grep ' = ([a-z_]*) *[a-z]' '*.c'
to find assignments that cast, but nothing looked like a function.
The resulting code is unfortunately a little longer, but the bonus of
using container_of() is that we are no longer restricted to the
hashmap_entry being at the start of the struct.

Windows updates.
* ds/maintenance-on-windows-fix:
git maintenance: avoid console window in scheduled tasks on Windows
win32: add a helper to run `git.exe` without a foreground window
|

"git bisect visualize" stopped running "gitk" on Git for Windows
when the command was reimplemented in C around Git 2.34 timeframe.
This has been corrected.
* ma/locate-in-path-for-windows:
docs: update when `git bisect visualize` uses `gitk`
compat/mingw: implement a native locate_in_PATH()
run-command: conditionally define locate_in_PATH()
