ruby.git/ext/socket/rubysocket.h, branch v3_2_11

Add support for `sockaddr_un` on Windows. (#6513)

2022-11-17T22:50:25+00:00

* 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

Add connect_timeout to TCPSocket

2020-12-10T11:52:29+00:00

Add connect_timeout to TCPSocket.new in the same way as Socket.tcp.

Closes [Feature #17187]

Revert getaddrinfo_a()

2020-12-07T04:33:53+00:00

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.

Make Socket.getaddrinfo interruptible (#2827)

2020-08-27T07:39:13+00:00

Before, Socket.getaddrinfo was using a blocking getaddrinfo(3) call.
That didn't allow to wrap it into Timeout.timeout or interrupt the thread in any way.

Combined with the default 10 sec resolv timeout on many Unix systems, this can
have a very noticeable effect on production Ruby apps being not
resilient to DNS outages and timing out name resolution, and being unable to fail fast even
with Timeout.timeout.

Since we already have support for getaddrinfo_a(3), the async version
of getaddrinfo, we should be able to make Socket.getaddrinfo leverage that
when getaddrinfo_a version is available in the system (hence #ifdef
HAVE_GETADDRINFO_A).
