Issue #1152 has been updated by Yui NARUSE. Status changed from Open to Assigned Assignee set to Shugo Maeda ---------------------------------------- Bug #1152: profiler.rb is not concurrent-execution threadsafe http://redmine.ruby-lang.org/issues/1152 Author: Charles Nutter Status: Assigned Priority: Normal Assignee: Shugo Maeda Category: Target version: ruby -v: all versions 1.8.6 and up =begin 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. =end -- http://redmine.ruby-lang.org
