[ruby-core:40890] [ruby-trunk - Bug #5556] SIGHUP no longer ignored when sent to process group from a subprocess

From: Brian Ford <brixen@...>
Date: 2011-11-09 18:27:53 UTC
List: ruby-core #40890
Issue #5556 has been updated by Brian Ford.


The use case is any reason someone would send a signal to the process group but not want the parent process to abort. I'm quite sure there is existing code that depends on this behavior even by accident. The fact that it changed will affect some programs that have previously not ignored HUP, so people will likely get puzzling process exits in cases such as I discovered here by accident, ie on process subprocessing worker processes.

I really don't care what the behavior is as long as it is documented and tested. If you can point me to tests for this, I'll adapt them for RubySpec.

I have no idea what you mean by "signal handler is per-process resource", how would it not be a per-process resource? Or do you have a definition of per-process where process is not an OS process? How does per-process and thread-safety relate? Seems like we should have a glossary of terms as MRI defines them to avoid some confusion here.

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: Feedback
Priority: Normal
Assignee: Motohiro KOSAKI
Category: core
Target version: 2.0.0
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
