Hello,

I have come across a deadlock situation (of the entire ruby interpreter) when using ::Socket.pair.

I have attached a simple example script to trigger the issue (Using mutex's to synchronize the read/writes does not help).

I am using ruby 1.9.1p243 (2009-07-16 revision 24175) on Windows 32bit.

Thanks.

with mingw, I get

c:\dev_old\digitalarchive_trunk>ruby -v bad.rb
ruby 1.9.1p376 (2009-12-07 revision 26041) [i386-mingw32]
bad.rb:7:in pair': pair() function is unimplemented on this machine (NotImplementedError) from bad.rb:7:in

'

Anybody know why that would be?

Narrowed this issue down to the cygwin build.

Works correctly on the following:
* ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]
* ruby 1.9.0 (2008-06-20 revision 17482) [i486-linux]
* ruby 1.9.1p243 (2009-07-16 revision 24175) [i486-linux]

Deadlocks on the following:
* ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-cygwin]

AFAIK Ruby on Windows doesn't support ::Socket.pair (Hence the NotImplementedError), I forgot I was using the cygwin build.

seemed to work ok for me with cygwin 1.8.7 (if that's helpful)
