633023 - xpcshell needs -p (enable profiling)

Status: RESOLVED FIXED

(Core :: XPConnect, defect)

Description

[Jesse Ruderman]

Attachment: patch

Based on the patch for bug 603558.

I don't know how to test that this actually works. Are there any known profiling bugs I could try to trigger in xpcshell with this patch?

To see if it works, set the environment variable TMFLAGS=profiler. The run a script like this:

for (var i=0; i<100; i++) print(i);

You should get some output from the profiler if you run with -m -j -p.

Yep, that worked :)  It prints some extra stuff around iteration 60 with -p, but not without -p.

TMFLAGS=profiler ~/tracemonkey/debug-obj/dist/bin/xpcshell -j -m -p -e "for (var i=0; i<100; i++) print(i);"
