Fix broken links to `Socket.tcp_fast_fallback=`

2024-12-15T06:36:08+00:00

Since it's a singleton method, it should be referenced as `Socket.tcp_fast_fallback=`,
not `Socket#tcp_fast_fallback=`.

Improve APIs for Globally Enabling/Disabling fast_fallback in Socket (#12257)

2024-12-14T06:51:19+00:00

This change includes the following updates:
- Added an environment variable `RUBY_TCP_NO_FAST_FALLBACK` to control enabling/disabling fast_fallback
- Updated documentation and man pages
- Revised the implementation of Socket.tcp_fast_fallback= and Socket.tcp_fast_fallback, which previously performed dynamic name resolution of constants and variables. As a result, the following performance improvements were achieved:

(Case of 1000 executions of `TCPSocket.new` to the local host)

Support `IO#timeout` for `rsock_connect`. (#11880)

2024-10-11T21:08:34+00:00

Update `rsock_connect` to take `VALUE io` argument. (#11847)

2024-10-11T05:36:11+00:00

Rename rsock_raise_socket_error to rsock_raise_resolution_error

2023-11-30T04:27:19+00:00

Again, rsock_raise_socket_error is called only when getaddrinfo and getaddrname fail

Don't check for null pointer in calls to free

2023-06-30T13:13:31+00:00

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 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

[Feature #18491] Drop support for HP-UX

2022-01-18T14:52:15+00:00

IA64 support was dropped in ticket #15894, so we can drop support for
HP-UX.
