Subject: [ruby-core:36696] [Ruby 1.9 - Bug #4777][Third Party's Issue] Ruby 1.9.2-p180 ignoring INT, TERM, and QUIT until it receives CONT


Issue #4777 has been updated by Motohiro KOSAKI.

Status changed from Feedback to Third Party's Issue

Nice information!! 

But unfortunately, I've confirmed ruby-1.9.2p180 + Fedora15 + your test case doesn't reproduce the issue.
Also strace doesn't show any ruby fault. We have to conclude it's Ubuntu specific issue. I'm sorry.

Bug #4777: Ruby 1.9.2-p180 ignoring INT, TERM, and QUIT until it receives CONT

We're having an intermittent but fairly frequent issue with a resque worker process that we're daemonizing with daemontools on Ubuntu 10.04 LTS

When we send a QUIT or TERM signal to the process, it is not handled.
When we send a CONT, the process traps and handles QUIT and TERM signals that were ignored just before handling the CONT.
It's as if the CONT frees the signals that were previously ignored.
