[ruby-core:28390] [Bug #2739] ruby 1.8.7 built with pthreads hangs under some circumstances

From: Lucas Nussbaum <redmine@...>
Date: 2010-03-01 22:31:02 UTC
List: ruby-core #28390
Issue #2739 has been updated by Lucas Nussbaum.


After more investigation (see https://bugs.launchpad.net/ubuntu/+source/ruby1.8/+bug/520715 for the details), here are some conclusions.

Using this test case:
<------------------
#!/usr/bin/ruby1.8

%x{/usr/bin/touch /tmp/7777}
puts "executed without timeout ok"
puts "executing with timeout"
require 'timeout'
status = Timeout::timeout(5) {
%x{/usr/bin/touch /tmp/7777}
}
puts "executed with timeout ok"
--------------------------->

The above test case:
- runs fine on Debian unstable (using GLIBC 2.10)
- hangs on Debian unstable using the GLIBC packages from Debian experimental, version 2.11.0
- hangs on Ubuntu Lucid (which GLIBC 2.11.0)
Both Debian unstable and Ubuntu lucid use Ruby 1.8.7 (2010-01-10 patchlevel 249)

By "hangs", I mean:
$ while ruby1.8 te.rb ; do true; done
executed without timeout ok
executing with timeout
executed with timeout ok
executed without timeout ok
executing with timeout
/usr/lib/ruby/1.8/timeout.rb:60: execution expired (Timeout::Error)
	from te.rb:11

It is not clear whether this is a GLIBC or a Ruby issue. However, it would be fantastic if a Ruby developer with insight in the Ruby threading code could take a look.
