Bug #1152

closed

profiler.rb is not concurrent-execution threadsafe

Added by headius (Charles Nutter) about 15 years ago. Updated over 11 years ago.

Status:
Closed
Target version:
ruby -v:
all versions 1.8.6 and up
Backport:
[ruby-core:22046]

Description

=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
