470153 - Scan the web to find out which TraceMonkey aborts we hit

Status: RESOLVED WONTFIX

(Testing :: General, enhancement)

Description

[Jesse Ruderman]

It would be good to know which tracemonkey aborts are hit by the most real-world web pages.  Bob, are you interested?  We could add a new mode that prints messages on stdout when aborts happen (like TRACEMONKEY=verbose but less verbose), or we could make the shutdown jitstats more detailed.

I came up with this idea during an argument with Brendan.  I was arguing that we should try to trace a particular piece of code that we currently abort on, and he was arguing that it wasn't a common code pattern.  Data from real-world web pages would solve this kind of argument.

tomcat is setting up to run top site scans of the homepages of the top 100,000 sites looking for leaks and crashes. We could leverage that run and get the data you are interested in. tomcat, we'll probably want to stop the run with mozilla-1.9.1 and start again either with mozilla-central or tracemonkey (wherever this lands and jesse/brendan suggest).

Just starting out with visiting the top N pages and see whether we crash with JIT on would be great.

Hi Andreas, ok, Topsite Runs for Top100000 Sites are running for Mac and Linux (Linux will follow tomorrow). I will report back when the Tests are finished.

Taking this Bug for now.

Obsolete with the removal of tracejit.
