It looks like `sched_getcpu(3)` returns a strange number on some
(virtual?) environments.
I decided to remove the setaffinity mechanism because the performance
does not appear to degrade on a quick benchmark even if removed.
[Bug #20172]
When making an outgoing TCP or UDP connection, set AI_ADDRCONFIG in the
hints we send to getaddrinfo(3) (if supported). This will prompt the
resolver to _NOT_ issue A or AAAA queries if the system does not
actually have an IPv4 or IPv6 address (respectively).
This makes outgoing connections marginally more efficient on
non-dual-stack systems, since we don't have to try connecting to an
address which can't possibly work.
More importantly, however, this works around a race condition present
in some older versions of glibc on aarch64 where it could accidently
send the two outgoing DNS queries with the same DNS txnid, and get
confused when receiving the responses. This manifests as outgoing
connections sometimes taking 5 seconds (the DNS timeout before retry) to
be made.
Fixes#19144
When pthread_create is available, rb_getaddrinfo creates a pthread and
executes getaddrinfo(3) in it. The caller thread waits for the pthread
to complete, but detaches it if interrupted. This allows name resolution
to be interuppted by Timeout.timeout, etc. even if it takes a long time
(for example, when the DNS server does not respond). [Feature #19965]
The socket extensions rubysocket.h pulls in the "private" include/gc.h,
which now depends on vm_core.h. vm_core.h pulls in id.h
when tool/update-deps generates the dependencies for the makefiles, it
generates the line for id.h to be based on VPATH, which is configured in
the extconf.rb for each of the extensions. By default VPATH does not
include the actual source directory of the current Ruby so the
dependency fails to resolve and linking fails.
We need to append the topdir and top_srcdir to VPATH to have the
dependancy picked up correctly (and I believe we need both of these to
cope with in-tree and out-of-tree builds).
I copied this from the approach taken in

* 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

getaddrinfo_a() gets stuck after fork().
To avoid this, we need 1 second sleep to wait for internal
worker threads of getaddrinfo_a() to be finished, but that is unacceptable.
[Bug #17220] [Feature #17134] [Feature #17187]
Addrinfo.getaddrinfo and .foreach now accepts :timeout in seconds as
a keyword argument. If getaddrinfo_a(3) is available, the timeout will be
applied for name resolution. Otherwise, it will be ignored.
Socket.tcp accepts :resolv_timeout to use this feature.

Test was failed on Solaris machines which don't have "http" in
/etc/services. In this commit, use "ssh" instead.

* ext/socket/extconf.rb: use system getaddrinfo, getnameinfo, and

with addrinfo.h and cannot compile. conftest.exe linked against
msvcr90.dll segfaults when invoked in extconf.rb for unknown
reason, and failed to check them.
