In the preceding [1] (pack-objects: move revs out of
get_object_list(), 2022-03-22) the "repo_init_revisions()" was moved
to cmd_pack_objects() so that it unconditionally took place for all
invocations of "git pack-objects".
We'd thus start leaking memory, which is easily reproduced in
e.g. git.git by feeding e83c5163316 (Initial revision of "git", the
information manager from hell, 2005-04-07) to "git pack-objects";
$ echo e83c5163316f89bfbde7d9ab23ca2e25604af290 | ./git pack-objects initial

Narrowly fixing that commit would have been easy, just add call
repo_init_revisions() right before get_object_list(), which is
effectively what was done before that commit.
But an unstated constraint when setting it up early is that it was
needed for the subsequent [2] (pack-objects: parse --filter directly
into revs.filter, 2022-03-22), i.e. we might have a --filter
command-line option, and need to either have the "struct rev_info"
setup when we encounter that option, or later.
Let's just change the control flow so that we'll instead set up the
"struct rev_info" only when we need it. Doing so leads to a bit more
verbosity, but it's a lot clearer what we're doing and why.
An earlier version of this commit[3] went behind
opt_parse_list_objects_filter()'s back by faking up a "struct option"
before calling it. Let's avoid that and instead create a blessed API
for this pattern.
We could furthermore combine the two get_object_list() invocations
here by having repo_init_revisions() invoked on &pfd.revs, but I think
clearly separating the two makes the flow clearer. Likewise
redundantly but explicitly (i.e. redundant v.s. a "{ 0 }") "0" to
"have_revs" early in cmd_pack_objects().
While we're at it add parentheses around the arguments to the OPT_*
macros in in list-objects-filter-options.h, as we need to change those
lines anyway. It doesn't matter in this case, but is good general
practice.

Measure the time taken to apply the FSMonitor query result
to the index and the untracked-cache.
Set the `FSMONITOR_CHANGED` bit on `istate->cache_changed` when
FSMonitor returns a very large repsonse to ensure that the index is
written to disk.
Normally, when the FSMonitor response includes a tracked file, the
index is always updated. Similarly, the index might be updated when
the response alters the untracked-cache (when enabled). However, in
cases where neither of those cause the index to be considered changed,
the FSMonitor response is wasted. Subsequent Git commands will make
requests with the same token and receive the same response.
If that response is very large, performance may suffer. It would be
more efficient to force update the index now (and the token in the
index extension) in order to reduce the size of the response received
by future commands.
This was observed on Windows after a large checkout. On Windows, the
kernel emits events for the files that are changed as they are
changed. However, it might delay events for the containing
directories until the system is more idle (or someone scans the
directory (so it seems)). The first status following a checkout would
get the list of files. The subsequent status commands would get the
list of directories as the events trickled out. But they would never
catch up because the token was not advanced because the index wasn't
updated.
This list of directories caused `wt_status_collect_untracked()` to
unnecessarily spend time actually scanning them during each command.

Teach fsmonitor--daemon client threads to create a cookie file
inside the .git directory and then wait until FS events for the
cookie are observed by the FS listener thread.
This helps address the racy nature of file system events by
blocking the client response until the kernel has drained any
event backlog.
This is especially important on MacOS where kernel events are
only issued with a limited frequency. See the `latency` argument
of `FSeventStreamCreate()`. The kernel only signals every `latency`
seconds, but does not guarantee that the kernel queue is completely
drained, so we may have to wait more than one interval. If we
increase the latency, the system is more likely to drop events.
We avoid these issues by having each client thread create a unique
cookie file and then wait until it is seen in the event stream.

Teach fsmonitor--daemon to periodically truncate the list of
modified files to save some memory.
Clients will ask for the set of changes relative to a token that they
found in the FSMN index extension in the index. (This token is like a
point in time, but different). Clients will then update the index to
contain the response token (so that subsequent commands will be
relative to this new token).
Therefore, the daemon can gradually truncate the in-memory list of
changed paths as they become obsolete (older than the previous token).
Since we may have multiple clients making concurrent requests with a
skew of tokens and clients may be racing to the talk to the daemon,
we lazily truncate the list.
We introduce a 5 minute delay and truncate batches 5 minutes after
they are considered obsolete.

Teach `test-tool.exe chmtime` to ignore errors when setting the mtime
on a directory on Windows.
NEEDSWORK: The Windows version of `utime()` (aka `mingw_utime()`) does
not properly handle directories because it uses `_wopen()`. It should
be converted to using `CreateFileW()` and backup semantics at a minimum.
Since I'm already in the middle of a large patch series, I did not want

Do not copy any of the various fsmonitor--daemon files from the .git
directory of the (GIT_PREF_REPO or GIT_PERF_LARGE_REPO) source repo
into the test's trash directory.
When perf tests start, they copy the contents of the source repo into
the test's trash directory. If fsmonitor is running in the source repo,
there may be control files, such as the IPC socket and/or fsmonitor
cookie files. These should not be copied into the test repo.
Unix domain sockets cannot be copied in the manner used by the test
setup, so if present, the test setup fails.
Cookie files are harmless, but we should avoid them.
The builtin fsmonitor keeps all such control files/sockets in
.git/fsmonitor--daemon*, so it is simple to exclude them.

Add the "feature: fsmonitor--daemon" message to the output of
`git version --build-options`.
The builtin FSMonitor is only available on certain platforms and
even then only when certain Makefile flags are enabled, so print
a message in the verbose version output when it is available.
This can be used by test scripts for prereq testing. Granted, tests
could just try `git fsmonitor--daemon status` and look for a 128 exit
code or grep for a "not supported" message on stderr, but these
methods are rather obscure.
The main advantage is that the feature message will automatically
appear in bug reports and other support requests.
This concept was also used during the development of Scalar for
similar reasons.

Include MacOS system declarations to allow us to use FSEvent and
CoreFoundation APIs. We need different versions of the declarations
for GCC vs. clang because of compiler and header file conflicts.
While it is quite possible to #include Apple's CoreServices.h when
compiling C source code with clang, trying to build it with GCC
currently fails with this error:

| ^~~~~
The underlying reason is that GCC (rightfully) objects that an `enum`
value such as `kAuthorizationExternalFormLength` is not a constant
(because it is not, the preprocessor has no knowledge of it, only the
actual C compiler does) and can therefore not be used to define the size
of a C array.
This is a known problem and tracked in GCC's bug tracker:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93082
In the meantime, let's not block things and go the slightly ugly route
of declaring/defining the FSEvents constants, data structures and
functions that we need, so that we can avoid above-mentioned issue.
Let's do this _only_ for GCC, though, so that the CI/PR builds (which
build both with clang and with GCC) can guarantee that we _are_ using
the correct data types.

Teach fsmonitor--daemon to build a list of changed paths and associate
them with a token-id. This will be used by the platform-specific
backends to accumulate changed paths in response to filesystem events.
The platform-specific file system listener thread receives file system
events containing one or more changed pathnames (with whatever
bucketing or grouping that is convenient for the file system). These
paths are accumulated (without locking) by the file system layer into
a `fsmonitor_batch`.
When the file system layer has drained the kernel event queue, it will
"publish" them to our token queue and make them visible to concurrent
client worker threads. The token layer is free to combine and/or de-dup
paths within these batches for efficient presentation to clients.

We want to report to clients changes to tracked and untracked

report changes within the .git directory, for example.
This classification will be used in a later commit by the
different backends to classify paths as events are received.

Implement 'git fsmonitor--daemon start' command. This command starts

We avoid the fork-and-call technique on Unix systems in favor of a

events. It also makes our usage more consistent with Windows usage.
On Windows, teach 'git fsmonitor--daemon run' to optionally call
'FreeConsole()' to release handles to the inherited Win32 console
(despite being passed invalid handles for stdin/out/err). Without
this, command prompts and powershell terminal windows could hang
in "exit" until the last background child process exited or released

Move fsmonitor config settings to a new and opaque
`struct fsmonitor_settings` structure. Add a lazily-loaded pointer
to this into `struct repo_settings`
Create an `enum fsmonitor_mode` type in `struct fsmonitor_settings` to
represent the state of fsmonitor. This lets us represent which, if
any, fsmonitor provider (hook or IPC) is enabled.
Create `fsm_settings__get_*()` getters to lazily look up fsmonitor-
related config settings.
Get rid of the `core_fsmonitor` global variable. Move the code to
lookup the existing `core.fsmonitor` config value into the fsmonitor
settings.
Create a hook pathname variable in `struct fsmonitor-settings` and
only set it when in hook mode.
Extend the definition of `core.fsmonitor` to be either a boolean
or a hook pathname. When true, the builtin FSMonitor is used.
When false or unset, no FSMonitor (neither builtin nor hook) is
used.
The existing `core_fsmonitor` global variable was used to store the
pathname to the fsmonitor hook *and* it was used as a boolean to see
if fsmonitor was enabled. This dual usage and global visibility leads
to confusion when we add the IPC-based provider. So lets hide the
details in fsmonitor-settings.c and let it decide which provider to
use in the case of multiple settings. This avoids cluttering up
repo-settings.c with these private details.
A future commit in builtin-fsmonitor series will add the ability to
disqualify worktrees for various reasons, such as being mounted from a
remote volume, where fsmonitor should not be started. Having the
config settings hidden in fsmonitor-settings.c allows such worktree
restrictions to override the config values used.

The implementation of test_subcommand_inexact() was originally
introduced in e4d0c11c0 (repack: respect kept objects with '--write-midx
-b', 2021-12-20) with the intention to allow finding a subcommand based
on an initial set of arguments. The inexactness was intended as a way to
allow flexible options beyond that initial set, as opposed to
test_subcommand() which requires that the full list of options is
provided in its entirety.
The implementation began by copying test_subcommand() and replaced the
repeated argument 'printf' statement to append ".*" instead of "," to
each argument. This caused it to be more flexible than initially
intended.
The previous change deleted the only use of test_subcommand_inexact, so
instead of editing the helper, delete it.

The '--write-midx -b packs non-kept objects' test in t7700-repack.sh
uses test_subcommand_inexact to check that 'git repack' properly adds
the '--honor-pack-keep' flag to the 'git pack-objects' subcommand.
However, the test_subcommand_inexact helper is more flexible than
initially designed, and this instance is the only one that makes use of
it: there are additional arguments between 'git pack-objects' and the
'--honor-pack-keep' flag. In order to make test_subcommand_inexact more
strict, we need to fix this instance.
This test checks that 'git repack --write-midx -a -b -d' will create a
new pack-file that does not contain the objects within the kept pack.
This behavior is possible because of the multi-pack-index bitmap that
will bitmap objects against multiple packs. Without --write-midx, the
objects in the kept pack would be duplicated so the resulting pack is
closed under reachability and bitmaps can be created against it. This is
discussed in more detail in e4d0c11c0 (repack: respect kept objects with
'--write-midx -b', 2021-12-20) which also introduced this instance of
test_subcommand_inexact.
To better verify the intended post-conditions while also removing this
instance of test_subcommand_inexact, rewrite the test to check the list
of packed objects in the kept pack and the list of the objects in the
newly-repacked pack-file _other_ than the kept pack. These lists should
be disjoint.
Be sure to include a non-kept pack-file and loose objects to be extra
careful that this is properly behaving with kept packs and not just
avoiding repacking all pack-files.

Change the "--immediate" option so that it emits valid TAP on
failure. Before this it would omit the required plan at the end,
e.g. under SANITIZE=leak we'd show a "No plan found in TAP output"
error from "prove":
$ prove t0006-date.sh :: --immediate
t0006-date.sh .. Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/22 subtests
Test Summary Report
-------------------
t0006-date.sh (Wstat: 256 Tests: 22 Failed: 1)
Failed test: 22
Non-zero exit status: 1
Parse errors: No plan found in TAP output
Files=1, Tests=22, 0 wallclock secs ( 0.02 usr 0.01 sys + 0.18 cusr 0.06 csys = 0.27 CPU)
Result: FAIL
Now we'll emit output that doesn't result in TAP parsing failures:
$ prove t0006-date.sh :: --immediate
t0006-date.sh .. Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/22 subtests

In the short help output from "git reset -h", the recently added
"--[no-]refresh" option is shown like so:
--refresh skip refreshing the index after reset
which explains what happens when the option is given in the negative
form, i.e. "--no-refresh". We could rephrase the explanation to
read "refresh the index after reset (default)" to hint that the user
can say "--no-refresh" to override the default, but listing the
"--no-refresh" form in the list of options would be more helpful.
