We'd like to be able to make some of our pipes nonblocking so that
poll() can be used effectively, but O_NONBLOCK isn't portable. Let's
introduce a compat wrapper so this can be abstracted for each platform.
The interface is as narrow as possible to let platforms do what's
natural there (rather than having to implement fcntl() and a fake
O_NONBLOCK for example, or having to handle other types of descriptors).
The next commit will add Windows support, at which point we should be
covering all platforms in practice. But if we do find some other
platform without O_NONBLOCK, we'll return ENOSYS. Arguably we could just
trigger a build-time #error in this case, which would catch the problem
earlier. But since we're not planning to use this compat wrapper in many
code paths, a seldom-seen runtime error may be friendlier for such a
platform than blocking compilation completely. Our test suite would
still notice it.

The function is copied *mostly* verbatim, with two exceptions:
* '#ifdef WIN32' is replaced with '#ifdef GIT_WINDOWS_NATIVE' to allow
'statvfs' to be used with Cygwin.

When an Administrator creates a file or directory, the created
file/directory is owned not by the Administrator SID, but by the
_Administrators Group_ SID. The reason is that users with administrator
privileges usually run in unprivileged ("non-elevated") mode, and their
user SID does not change when running in elevated mode.
This is is relevant e.g. when running a GitHub workflow on a build
agent, which runs in elevated mode: cloning a Git repository in a script
step will cause the worktree to be owned by the Administrators Group
SID, for example.
Let's handle this case as following: if the current user is an
administrator, Git should consider a worktree owned by the
Administrators Group as if it were owned by said user.

When verifying the ownership of the Git directory, we sometimes would

from Unix'), but only when it is a appropriate to actually say
something.
To allow for that, collect that information and hand it back to the

mkstemp() emulation on Windows has been improved.

* rs/mingw-tighten-mkstemp:
mingw: avoid mktemp() in mkstemp() implementation
Files' attributes can indicate more than just whether they are files or
directories. It was reported in Git for Windows that on certain network
shares, this led to a nasty problem trying to create tags:
$ git tag -a -m "automatic tag creation" test_dir/test_tag
fatal: cannot lock ref 'refs/tags/test_dir/test_tag': unable to resolve reference 'refs/tags/test_dir/test_tag': Not a directory
Note: This does not necessarily happen with all types of network shares.
One setup where it _did_ happen is a Windows Server 2019 VM, and as
hinted in
http://woshub.com/slow-network-shared-folder-refresh-windows-server/
in the indicated instance the following commands worked around the bug:
Set-SmbClientConfiguration -DirectoryCacheLifetime 0
Set-SmbClientConfiguration -FileInfoCacheLifetime 0
Set-SmbClientConfiguration -FileNotFoundCacheLifetime 0
This would impact performance negatively, though, as it essentially
turns off all caching, therefore we do not want to require users to do
that just to be able to use Git on Windows.
The underlying bug is in the code added in 4b0abd5c69 (mingw: let
lstat() fail with errno == ENOTDIR when appropriate, 2016-01-26) that
emulates the POSIX behavior where `lstat()` should return `ENOENT` if
the file or directory simply does not exist but could be created, and
`ENOTDIR` if there is no file or directory nor could there be because a
leading path already exists and is not a directory.
In that code, the return value of `GetFileAttributesW()` is interpreted
as an enum value, not as a bit field, so that a perfectly fine leading
directory can be misdetected as "not a directory".
As a consequence, the `read_refs_internal()` function would return
`ENOTDIR`, suggesting not only that the tag in the `git tag` invocation
above does not exist, but that it cannot even be created.
Let's fix the code so that it interprets the return value of the
`GetFileAttributesW()` call correctly.

Emit NFC or NFC and NFD spellings of pathnames on macOS.
MacOS is Unicode composition insensitive, so NFC and NFD spellings are
treated as aliases and collide. While the spelling of pathnames in
filesystem events depends upon the underlying filesystem, such as
APFS, HFS+ or FAT32, the OS enforces such collisions regardless of
filesystem.
Teach the daemon to always report the NFC spelling and to report
the NFD spelling when stored in that format on the disk.

Force shutdown fsmonitor daemon if the worktree root directory
is moved, renamed, or deleted.
Use Windows low-level GetFileInformationByHandle() to get and
compare the Windows system unique ID for the directory with a
cached version when we started up. This lets us detect the
case where someone renames the directory that we are watching
and then creates a new directory with the original pathname.
This is important because we are listening to a named pipe for
requests and they are stored in the Named Pipe File System (NPFS)
which a kernel-resident pseudo filesystem not associated with
the actual NTFS directory.
For example, if the daemon was watching "~/foo/", it would have
a directory-watch handle on that directory and a named-pipe
handle for "//./pipe/...foo". Moving the directory to "~/bar/"
does not invalidate the directory handle. (So the daemon would
actually be watching "~/bar" but listening on "//./pipe/...foo".
If the user then does "git init ~/foo" and causes another daemon
to start, the first daemon will still have ownership of the pipe
and the second daemon instance will fail to start. "git status"
clients in "~/foo" will ask "//./pipe/...foo" about changes and
the first daemon instance will tell them about "~/bar".
This commit causes the first daemon to shutdown if the system unique
ID for "~/foo" changes (changes from what it was when the daemon
started). Shutdown occurs after a periodic poll. After the
first daemon exits and releases the lock on the named pipe,
subsequent Git commands may cause another daemon to be started
on "~/foo". Similarly, a subsequent Git command may cause another
daemon to be started on "~/bar".

Create another thread to watch over the daemon process and
automatically shut it down if necessary.
This commit creates the basic framework for a "health" thread
to monitor the daemon and/or the file system. Later commits
will add platform-specific code to do the actual work.
The "health" thread is intended to monitor conditions that
would be difficult to track inside the IPC thread pool and/or
the file system listener threads. For example, when there are
file system events outside of the watched worktree root or if
we want to have an idle-timeout auto-shutdown feature.
This commit creates the health thread itself, defines the thread-proc
and sets up the thread's event loop. It integrates this new thread
into the existing IPC and Listener thread models.
This commit defines the API to the platform-specific code where all of
the monitoring will actually happen.
The platform-specific code for MacOS is just stubs. Meaning that the
health thread will immediately exit on MacOS, but that is OK and
expected. Future work can define MacOS-specific monitoring.
The platform-specific code for Windows sets up enough of the
WaitForMultipleObjects() machinery to watch for system and/or custom
events. Currently, the set of wait handles only includes our custom
shutdown event (sent from our other theads). Later commits in this
series will extend the set of wait handles to monitor other
conditions.

Teach FSMonitor daemon on Windows to recognize shortname paths as

possible).
Sometimes we receive FS events using the shortname, such as when a CMD
shell runs "RENAME GIT~1 FOO" or "RMDIR GIT~1". The FS notification
arrives using whatever combination of long and shortnames were used by
the other process. (Shortnames do seem to be case normalized,
however.)
Use Windows GetLongPathNameW() to try to map the pathname spelling in
the notification event into the normalized longname spelling. (This
can fail if the file/directory is deleted, moved, or renamed, because
we are asking the FS for the mapping in response to the event and
after it has already happened, but we try.)

Git for Windows' SDK recently upgraded to GCC v12.x which points out

Since a subset of this SDK is used in Git's CI/PR builds, we need to fix

Note: This bug has been with us since 2a6b149c64 (mingw: avoid using

the hand-rolled string manipulation with a `strbuf`-based one, that

is called as part of the function in `daemon.c` which is set as the
`die()` routine, and since `strbuf_grow()` can call that function if it
runs out of memory, this would cause a nasty infinite loop that we do

checks for "'/' || '\\'" with the new is_xplatform_dir_sep(). As can
