Bug #8997: TestSignal#test_hup_me hangs up the test suite
https://bugs.ruby-lang.org/issues/8997

Author: vo.x (Vit Ondruch)
Status: Open
Priority: Normal
Assignee: kosaki (Motohiro KOSAKI)
Category: 
Target version: 
ruby -v: ruby 2.1.0dev (2013-09-22 trunk 43011) [i386-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


The TestSignal#test_hup_me was introduced in r39819 and there were attempt to fix some deadlock issue in r39862. However, I can still observe deadlock on Fedora Rawhide's builders. Not sure what is the cause, since I cannot reproduce it locally on my computer. Any idea what might be the cause? There are only two differences I can think of between my environment and the builders (1) the builders are virtualized guest systems (2) there is no network connectivity available. Both of these looks to be improbable cause of the deadlock.

Going to disable the test case for now:
sed -i '/def test_hup_me/,/end if Process.respond_to/ s/^/#/' test/ruby/test_signal.rb
