--profile needs to dump even on ^C, other means of getting info, multi-thread
-----------------------------------------------------------------------------
Key: JRUBY-5213
URL: http://jira.codehaus.org/browse/JRUBY-5213
Project: JRuby
Issue Type: Improvement
Affects Versions: JRuby 1.6
Reporter: Charles Oliver Nutter
Assignee: Thomas E Enebo
Fix For: JRuby 1.6
--profile support was added in 1.5.5, but there are many improvements needed:
* If the JVM exits with ^C, profile information is not dumped anywhere. For
server apps like Rails, this means you can't get profile data out.
* There's no way to get profile data from a running process. We should add an
mbean and a command-line tool to allow dumping live profile data.
* Only the main thread is profiled. We need to add profile dumping for all
threads, and allow showing profile data for threads individually or in
aggregate.
