2025-11-23T04:55:15+00:00

It should check the type of the argument and coercion before
converting the encoding.

Reduce the number of times IO is passed in send_io/recv_io test

2023-10-25T11:37:21+00:00

Since Linux 4.5, sendmsg(2) fails with ETOOMANYREFS if the number of
"in-flight" IOs, which has been sent by sendmsg(2) but has not yet
accepted by recvmsg(2), exceeds the RLIMIT_NOFILE resource limit.

```
  1) Error:
TestSocket_UNIXSocket#test_fd_passing_race_condition:
Errno::ETOOMANYREFS: Too many references: cannot splice - sendmsg(2)
```

This change reduces the number of times of IO passing under 1024,
which is a default limit in many environments.

TestSocket_UNIXSocket: stop testing empty packets

2023-08-31T14:43:58+00:00

OpenBSD and Solaris behave differently here.

Linux does deliver the empty packet, which is questionable
as it's undistinguishable from a closed connection.

It seems that OpenBSD and Solaris simply drop it.

We could test the platform before doing the assertion, but
it would likely be fragile, and the entire web recommend
to not ever send an empty packet, so the value of this
assertion is low.

BasicSocket#recv* return `nil` rather than an empty packet

2023-08-30T08:07:18+00:00

[Bug #19012]

man recvmsg(2) states:

> Return Value
> These calls return the number of bytes received, or -1 if an error occurred.
> The return value will be 0 when the peer has performed an orderly shutdown.

Not too sure how one is supposed to make the difference between a packet of
size 0 and a closed connection.

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
