From: Brian Ford Date: 2011-11-03T08:07:23+09:00 Subject: [ruby-core:40688] [ruby-trunk - Bug #5556][Open] SIGHUP no longer ignored when sent to process group from a subprocess Issue #5556 has been reported by Brian Ford. ---------------------------------------- Bug #5556: SIGHUP no longer ignored when sent to process group from a subprocess http://redmine.ruby-lang.org/issues/5556 Author: Brian Ford Status: Open Priority: Normal Assignee: Category: Target version: ruby -v: ruby 2.0.0dev (2011-11-01 trunk 33596) [x86_64-darwin10.8.0] Hi, Prior to 2.0.0dev, this script: sasha:rubinius brian$ cat process.rb puts "before system" system("ruby -e 'Process.kill(:HUP, 0)'") puts "after system" would print the following: sasha:rubinius brian$ ruby1.9.2 -v process.rb ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin10.8.0] before system after system Basically, SIGHUP was ignored when sent from a subprocess. Presently, this is the result: sasha:rubinius brian$ ruby -v process.rb ruby 2.0.0dev (2011-11-01 trunk 33596) [x86_64-darwin10.8.0] before system Hangup The following issue may be related, but the explanation is in Japanese, so I cannot follow it: http://redmine.ruby-lang.org/issues/4765 Is this change intentional? I discovered it running RubySpec, where there are specs for the behavior of sending SIGHUP to the process group. Thanks, Brian -- http://redmine.ruby-lang.org
