ruby.git/test/ruby/test_file_exhaustive.rb, branch v3_4_9

Skip some tests which don't work under permissionless containers

2024-08-22T23:34:41+00:00

When running as UID 0 but without CAP_DAC_OVERRIDE (for example, in a
docker container running with --uid 0 but --cap-drop=all), these tests
won't work because of hard-coded assumptions about what uid 0 can and
can't do.

Extend timeout in test/ruby/test_file_exhaustive.rb

Use `File::NULL` instead of hard coded null device names

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

Use an empty string when building File.expand_path

2022-04-12T13:54:57+00:00

Allocating a string of length MAXPATHLEN and then shrinking the string
is inefficient when the resulting path is short. Preallocating a large
string is also a problem for Variable Width Allocation since we can't
easily downsize the capacity.

I ran the following benchmark:

```ruby
Benchmark.ips do |x|
  {
    "empty" => "",
    "short" => "a/" * 10,
    "medium" => "a/" * 100,
    "long" => "a/" * 500
  }.each do |name, path|
    x.report(name) do |times|
      i = 0
      while i < times
        File.expand_path(path)
        i += 1
      end
    end
  end
end
```
