From: Charles Nutter Date: 2009-02-13T07:53:31+09:00 Subject: [ruby-core:22046] [Bug #1152] profiler.rb is not concurrent-execution threadsafe Bug #1152: profiler.rb is not concurrent-execution threadsafe http://redmine.ruby-lang.org/issues/show/1152 Author: Charles Nutter Status: Open, Priority: Normal ruby -v: all versions 1.8.6 and up The library profiler.rb uses class variables to store data without wrapping them in mutexes. On current C Ruby, this may only rarely cause a problem, but as more and more code is allowed to run in parallel it's going to lead to issues. If I or other JRuby community members have a chance, we'll try to make it thread-safe, but I wanted to file this issue to ensure it's out there. The library is also largely unchanged in 1.9.1. See http://jira.codehaus.org/browse/JRUBY-2133 for the (admittedly sparse) JRuby issue. ---------------------------------------- http://redmine.ruby-lang.org
