* [win32] fix compilation for windows-arm64
Credits to MSYS2 Ruby package using this patch.
* [win32] nm use full options
Fix compilation error when using MSYS2 environment.
Credits to MSYS2 Ruby package using this patch.
* [win32] detect llvm-windres (used for windows-arm64)
When adding preprocessor option for llvm-windres (using clang as
parameter), it fails. Thus, do not add this.
It's needed to be able to compile windows-arm64 version, because MSYS2
toolchain is LLVM based (instead of GCC/binutils).
* [win32] pioinfo detection for windows-arm64
This fixes "unexpected ucrtbase.dll" for native windows-arm64 ruby
binary. It does not solve issue with x64 version emulated on this
platform.
Value of pioinfo pointer can be found in ucrtbase.dll at latest adrp/add
sequence before return of _isatty function. This works for both release
and debug ucrt.
Due to the nature of aarch64 ISA (vs x86 or x64), it's needed to
disassemble instructions to retrieve offset value, which is a bit more
complicated than matching specific string patterns.
Details about adrp/add usage can be found in this blog post:

---
None of those revisions actually worked for both mswin and OpenBSD at
the same time. I need more time to build something that works for both.
While the $(VPATH) rules live in common.mk, mswin seems to ignore them.
We need to use $(VPATH) for OpenBSD, but we need to use the other one for mswin.
According to the C99 specification section 7.20.3.2 paragraph 2:
> If ptr is a null pointer, no action occurs.
So we do not need to check that the pointer is a null pointer.
* Add rb_io_path and rb_io_open_descriptor.
* Use rb_io_open_descriptor to create PTY objects
* Rename FMODE_PREP -> FMODE_EXTERNAL and expose it
FMODE_PREP I believe refers to the concept of a "pre-prepared" file, but
FMODE_EXTERNAL is clearer about what the file descriptor represents and
aligns with language in the IO::Buffer module.
* Ensure that rb_io_open_descriptor closes the FD if it fails
If FMODE_EXTERNAL is not set, then it's guaranteed that Ruby will be
responsible for closing your file, eventually, if you pass it to
rb_io_open_descriptor, even if it raises an exception.
* Rename IS_EXTERNAL_FD -> RUBY_IO_EXTERNAL_P
* Expose `rb_io_closed_p`.
* Add `rb_io_mode` to get IO mode.

When loading Ruby source files, we can save the result of
successful opens as open(2)/openat(2) are a fairly expensive
syscalls. This also avoids a time-of-check-to-time-of-use
(TOCTTOU) problem.
This reduces open(2) syscalls during `require'; but should be
most apparent when users have a small $LOAD_PATH. Users with
large $LOAD_PATH will benefit less since there'll be more
open(2) failures due to ENOENT.
With `strace -c -e openat ruby -e exit' under Linux, this
results in a ~14% reduction of openat(2) syscalls
(glibc uses openat(2) to implement open(2)).
% time seconds usecs/call calls errors syscall
------ ----------- ----------- --------- --------- ----------------
0.00 0.000000 0 296 110 openat
0.00 0.000000 0 254 110 openat
Additionally, the introduction of `struct ruby_file_load_state'
may make future optimizations more apparent.
This change cannot benefit binary (.so) loading since the
dlopen(3) API requires a filename and I'm not aware of an
alternative that takes a pre-existing FD. In typical
situations, Ruby source files outnumber the mount of .so
files.
HOMEPATH is set to "\WINDOWS\system32" when running per "runas" session.
This directory is not writable by ordinary users, leading to errors with many ruby tools.
Also config files in the home directory are not recognized.
Still keeping HOME at first which is not used by native Windows,
but by ruby specs and by MSYS2 environment.
Dir.home returns an UTF-8 string since ruby-3.0, but the actual
encoding of the bytes was CP_ACP or CP_OEMCP.
That led to invalid bytes when calling Dir.home with an unicode
username.

* Windows: Fix warning about undefined if_indextoname()
* Windows: Fix UNIXSocket on MINGW and make .pair more reliable
* Windows: Use nonblock=true for read tests with scheduler
* Windows: Move socket detection from File.socket? to File.stat
Add S_IFSOCK to Windows and interpret reparse points accordingly.
Enable tests that work now.
* Windows: Use wide-char functions to UNIXSocket
This fixes behaviour with non-ASCII characters.
It also fixes deletion of temporary UNIXSocket.pair files.
* Windows: Add UNIXSocket tests for specifics of Windows impl.
* Windows: fix VC build due to missing _snwprintf
Avoid usage of _snwprintf, since it fails linking ruby.dll like so:
linking shared-library x64-vcruntime140-ruby320.dll
x64-vcruntime140-ruby320.def : error LNK2001: unresolved external symbol snwprintf
x64-vcruntime140-ruby320.def : error LNK2001: unresolved external symbol vsnwprintf_l
whereas linking miniruby.exe succeeds.
This patch uses snprintf on the UTF-8 string instead.
Also remove branch GetWindowsDirectoryW, since it doesn't work.
* Windows: Fix dangling symlink test failures
Co-authored-by: Lars Kanis <kanis@comcard.de>
* Windows: Use readlink emulation for File.readlink
This fixes readlink emulation for the ERROR_MORE_DATA case and general error reporting.
It now releases GVL while readlink IO operation.
The dedicated rb_readlink was introduced in commit 2ffb87995a
in order to improve encoding and buffer allocation.
However the encoding issues are solved since ruby-3.0 switched to UTF-8
and the buffer allocation will be improved in a later commit.
* Windows: Increase the default buffer size for reparse point info
So far nearly all queries of reparse points needed two attempts to get enough buffer.
* Windows: Remove declaration of rb_w32_wreadlink
It was removed in commit 2f6fdd3aeb
esent.h is the header for MS essential storage engine (JET) which is not
needed in ruby. basetsd.h has existed since _MSC_VER >= 1200 (VS 6.0)
and is the preferred header to use for WCHAR.
