If a signal was received but was not dispatched before fork then
caught_signals counter should be reset. Closing of signal pipe makes
impossible to receive the signal that was counted.
There is no need in this signal because it was sent to parent process

Make sure this handle is functional. The Windows kernel seems to have a
bug that if the first use of AssignProcessToJobObject is for a Windows
Store program, subsequent attempts to use the handle with fail with
INVALID_PARAMETER (87). This is possilby because all uses of the handle
must be for the same Terminal Services session. We can ensure it is
tied to our current session now by adding ourself to it. We could
remove ourself afterwards, but there doesn't seem to be a reason to.

Secondly, we start the process suspended so that we can make sure we
added it to the job control object before it does anything itself (such
as launch more jobs or exit).

XNU kernels anno ~2010 had a data corrruption bug where concurrent
write and pwrite calls sometimes resulted in blocks of zeroes being
written instead of the actual data.

Libuv works around that by serializing all writes with a process-wide
mutex, meaning oncurrent writes (for all files, not just single files)
have a concurrency of 1. Obviously that's not great for performance.

Modern day macOS no longer has this bug, so remove the workaround.

Make printing handles from gdb a little easier because it doesn't always
know how to locate the stdout or stderr globals from libc.

With this commit `call uv_print_all_handles(0, 0)` prints the handles
from the default loop to stderr.

Switch from old-style ASSERT macro to new-style ASSERT_EQ,... macros.

Using new-style macros makes it easier to debug test failures

The previous implementation using si11v1cpcmodel did not return a valid
cpu model on z/OS. So use PCCA instead to correctly get the cpu model.

uid 0 is `qsecofr` on IBM i.

We can use the |bufs| argument directly instead of always copying it
and sometimes heap-allocating it.

The same trick doesn't work for uv_fs_write() because the iterator
mutates the buffers in the list and that's visible to the caller.

Fixes: #4038

Also introduce a new ASSERT_PTR_LT macro.

Under heavy workloads pthread_cond_wait on macOS can return EINVAL while
all the input parameters are correct.

As it happens due to a syscall having an errno of EBUSY we can detect it
and work around it.

Section 3 of rfc 5737 lists 192.0.2.0/24 as TEST-NET-1,
fix confusion about /8 and /24.

Implement in terms of pread/pwrite and only try to read/write the first
buffer. Callers are supposed to handle partial reads and libuv takes
care of partial writes.

(Our own fs_read_bufs test doesn't but that's fine because this commit
is a fix-up for unsupported platforms that aren't in our CI matrix.)

Fixes: #4176

uv__fs_write_do() calls it `r` so call it that in `uv__fs_read_do()`
too.

I split those out in a previous commit in anticipation of changes that
never came. Let's merge them back.

The recently added support for minidumps use SHGetKnownFolderPath which
requires shell32.lib - for some reason the builds work without that on
x64, while failing on arm.

The workaround for preadv/pwritev is needed only
for Solaris, not illumos, so avoid it on illumos.

Haiku R1/prebeta5 (and later) provide preadv and
pwritev, so only use workaround on lower versions.

It's been reported that no released kernels are bug-free enough to use
io_uring without causing regressions.

Fixes: #4158

Skip three fs_event tests that time out under Thread Sanitizer.

As promised in #2970, this attempts to migrate code to a common set of
utilities in a common place in the code and use them everywhere. This
also exports the functionality, since the Windows API with
WideCharToMultiByte is fairly verbose relative to what libuv and
libuv's clients typically need, so it is useful not to require clients
to reimplement this conversion logic unnecessarily (and because Windows
is not 64-bit ready here, but this implementation is.)

This makes cmake more consistent about how to name this file, otherwise
sometimes it names it uv.lib and sometimes libuv.a depending on which
compiler is selected or if ./configure is used.

Refs: #2085 (comment)

Fixes a detected error: incompatible pointer to integer conversion
passing 'uv_os_fd_t' (aka 'void *') to parameter of type 'SOCKET' (aka
'unsigned long long').

Use upstream llvm to work-around broken VS2022 clang unable to link.

For any API that takes a buffer and size pointer, check both pointers
and the pointed-to size and return UV_EINVAL in case of error.

Example:

```
int uv_foo(char* buffer, size_t* size) {
  if (buffer == NULL || size == NULL || *size == 0)
    return UV_EINVAL;
  ...
}
```

In order to "peek" the necessary size for dynamic allocation, the
following pattern can be used:

```
char *buf;
char scratch[1];
size_t len = sizeof(scratch);
int r;
r = uv_foo(scratch, &len);
assert(r == UV_ENOBUFS);
buf = malloc(len);
r = uv_foo(buf, &len);
...
```

Unsupported on FreeBSD, breaking the build.

This reverts commit b1d30f9.

`uv_thread_setname()` sets the name of the current thread. Different
platforms define different limits on the max number of characters
a thread name can be: Linux, IBMi (16), macOS (64), Windows (32767),
and NetBSD (32), etc. `uv_thread_setname()` will truncate it in case
`name` is larger than the limit of the platform.

`uv_thread_getname()` gets the name of the thread specified by `tid`.
The thread name is copied into the buffer pointed to by `name`. The
`size` parameter specifies the size of the buffer pointed to by `name`.
The buffer should be large enough to hold the name of the thread plus
the trailing NUL, or it will be truncated to fit.

Upgrade GHA image to Ubuntu 24.04 and use the distro-provided qemu.

It should not be necessary anymore to install qemu from .deb because
the stock qemu is new enough in 24.04.

Libuv looks for "Processor" in /proc/cpuinfo but it's been reported
that on at least some Raspberry Pi models, it's called "model name".
Look for both.

Fixes: nodejs/node#56105

io_uring support was default-disabled because of numerous kernel bugs
but those are all in the sqpoll (file i/o) parts of io_uring.

Batching of epoll_ctl calls through io_uring works fine, is a nice
optimization, and is therefore unconditionally enabled again.

The UV_USE_IO_URING environment variable now only affects sqpoll, and
only when the UV_LOOP_ENABLE_IO_URING_SQPOLL event loop flag is set.

Shuffle around and DRY the sendmsg logic in preparation for
uv_udp_try_send2(). NFC barring bugs.

This work was sponsored by ISC, the Internet Systems Consortium.

Add a version of uv_udp_try_send that can send multiple datagrams.

Uses sendmmsg(2) on platforms that support it (Linux, FreeBSD, macOS),
falls back to a regular sendmsg(2) loop elsewhere.

This work was sponsored by ISC, the Internet Systems Consortium.
