[ruby-core:88741] [Ruby trunk Bug#15043] MinGW intermittent test failure - TestIO#test_select_leak

Issue #15043 has been updated by MSP-Greg (Greg L).


@normalperson Eric,

Thanks for looking at it and also the patch.  It passed test-all, but as mentioned, it's intermittent and I can't repo it with ruby-loco...  Greg

@normalperson Eric,

Thought I'd ping you on this, as the test is very new.  The above test is not failing on Travis Ubuntu, nor Appveyor mswin or ruby-loco.


It is intermittently failing on the recently added Ruby Appveyor mingw job.  Console output is:

```
  1) Failure:
TestIO#test_select_leak [C:/projects/ruby/test/ruby/test_io.rb:3833]:
pid 1384 exit 1
| #<Thread:0x0000000001f9f8c0@-:11 run> terminated with exception (report_on_exception is true):
| select used to leak on exception (StandardError)
| -: select used to leak on exception (StandardError)
```

As far as I can tell, there are two main differences between ruby mingw & ruby-loco.  First, I'm passing a `-j` parameter to the test framework, Ruby mingw is passing it to the make command.  Secondly, I'm updating the build system (MSYS2/MinGW), Ruby mingw is not.  Appveyor can get a few months behind.

I ran the test file a few times locally using runner.rb, both normal & parallel.  All tests passed, two skips when run normal, eight skips when run parallel.

Finally, the Appveyor VM's have two procs, I believe Travis' Vm's are four.  Build/test times can vary quite a bit on Appveyor.

Thanks, Greg
