SafeSearch (enabled by default) already moves this near the end of the
search list. This flag (added in Windows 8) removes it entirely. This
may enhance security of applications that depend on libuv, at the high
risk of breaking applications that expected to be able to open
libraries by a relative path without a path separator (e.g. just the
file name).
As of recent, the fs_partial_read and fs_partial_write tests reliably
fail on that architecture.
An upgrade from Ubuntu 20.04 to 22.04 on the CI machines is suspected,
not any changes in libuv itself.
Perhaps it's possible to work around it in the tests but as Alpha is a
dead architecture, it doesn't seem worthwhile to sink time in that.
Let's remove it from the CI matrix instead.

Return `UV_EAGAIN` on `ERROR_OPERATION_ABORTED`.
Use the correct format for `overlapped.hEvent`.
Some refactoring to always wait for the overlapped result.
Modernize tests and some improvements.
Calling uv_fs_fstat for file types other then disk type was resulting in
error on Windows while it was retrieving data on Linux. This change
enables getting fstat for pipes and character files on Windows with data
fetched being as reasonable as possible.
A simple test is also added to check this behavior on all platforms. It
uses stdin, stdout and stderr. uv_fs_fstat needs to pass with disk files
pipes and character files (eg. console).

The old Linux baseline was essentially RHEL 6 but that distro has been
out of support for two years now. Move to RHEL 7.
This commit also moves FreeBSD to tier 2 because it isn't actually
part of libuv's CI matrix, only Node's.

The following metrics are now always recorded and available via the new
uv_metrics_info() API.
* loop_count: Number of event loop iterations.
* events: Total number of events processed by the event handler.
* events_waiting: Total number of events waiting in the event queue when
the event provider request was made.
Benchmarking has shown no noticeable impact recording these metrics.

Make unices and windows consistent when closing a pipe while it's
connecting so they all return `UV_ECANCELED`.
Avoid race condition between `pipe_connect_thread_proc()` and `uv_close()` when
accessing `handle->name`.

So `WaitNamedPipe()` doesn't fail. Increase the number of clients in
`pipe_connect_multiple` so `CreateFile()` returns `ERROR_PIPE_BUSY` and
the codepath leading to `WaitNamedPipe()` is exercised.
This reverts commit 87f076515937345fda1a1dbc598f34e65e1b81c7 and
implements a work-around instead. This has been reported to be
unnecessary, and also returns the wrong answer (off by exactly 100x),
so it is not particularly useful.
This also reverts the bugfixes to the original PR:
Revert "darwin: fix iOS compilation and functionality"
This reverts commit 1addf9b88a17bc32d009d377a14d540ccddd06db.
Revert "macos: fix the cfdata length in uv__get_cpu_speed (#3356)"
This reverts commit 1e7074913e1d2a1be72b62ba807325c14b0b317a.
Revert "darwin: fix -Wsometimes-uninitialized warning"
This reverts commit 6085bcef8dea1eaa21a92e2b6e6f03a0476b6c54.
Revert "macos: fix memleaks in uv__get_cpu_speed"
This reverts commit d2482ae121e0ae5d0cf0934b2e93cee81a4ac5ed.
The expected behavior on failure to read this info is to report 0 (for

d7a1/src/unix/linux.c#L834), which is which was not the case before
this PR for macos.
However hw.cpufrequency sysctl seems to be missing on darwin/arm64
(Apple Silicon), so we instead hardcode a plausible value. This value
matches what the mach kernel will report when running Rosetta apps.

Backported thread affinity feature and related dependency commits
from master. It will add support for those APIs: uv_cpumask_size,
uv_thread_setaffinity, uv_thread_getaffinity.
The supported platforms are Linux, Freebsd, and Windows.
Empty implementations (returning UV_ENOTSUP) on non-supported platforms
(such as OS X and AIX).
In the old version of uv_pipe_open, the parent process ID is used
always. If the open pipe is used in the same process, the parent
process will be obtained incorrectly.
Now we first get the client pid and compare it with its own pid. If it
is the same, then get the server pid. If the two are the same, then the
pipe is from the same process.

- unpoison results from linux system call wrappers
- unpoison results from stat/fstat/lstat to pacify clang 14
(fixed in later versions)
- add MSAN build option
- turn on MSAN CI build
I split up linux.c around 2012 for no real reason and now I'm merging
it back together, again for no real reason.
I half-jest. I like the idea of having everything together because I
practically forgot linux-inotify.c existed. It also makes io_uring
experiments a little easier.
Last but not least, it removes about 100 lines of license boilerplate.
preadv, pwritev, dup3 and utimensat all exist in 2.6.32 kernels, libuv's
minimum supported kernel.
The wrapper for utimensat was already gone, only the define remained.
I recently changed it to download a fixed .deb but seems it's updated
more frequently than I anticipated because the dfsg-7ubuntu1_package is
already gone, replaced with dfsg-7ubuntu2.
Bring back the downloader logic that fetches the filename from the
directory listing.
uv_fs_scandir() leaked an entry when you called it on a directory with
a single entry _and_ you didn't run the iterator until UV_EOF.

epoll.c is only used on Android and Linux after commit 5fe59726 ("sunos:
restore use of event ports") so move it back into linux-core.c
This commit removes a workaround for pre-2.6.27 kernels that don't have
the epoll_create1() system call.
Remove the TODO that says to batch up kevent(EV_DELETE) system calls.
It's unduly complicated in case of errors.
If you pass an out array to kevent(), it will store error records that
tell you which file descriptor caused the error but it also stores new
events in the array, complicating state management.
If you don't pass an out array, it simply doesn't tell you anything
except that _something_ failed. Optimistically trying batch deletion
and falling back to one-by-one deletion is probably possible but is
something of a deoptimization and also feels somewhat dangerous.
macOS has a mostly-undocumented kevent_qos() system call that accepts a
KEVENT_FLAG_ERROR_EVENTS flag that fixes the first problem but that of
course isn't portable.
Long story short, it seems like too much hassle for too little payoff.
Libuv has been doing one-by-one deletion for over a decade now and no
one complained about performance so far so let's just stick with that.
