1409953 - Make PCToLineNumber stop hanging the Gecko profiler

Status: NEW

(Core :: JavaScript Engine, enhancement, P2)

Description

[Boris Zbarsky [:bzbarsky]]

The real underlying problem here is bug 929950, but that doesn't seem to have real traction.

In the meantime, could we do something where the Gecko profiler gives up on accurate JS line/column information if it would take too long to gather it?  For my typical use cases (profiling C++ code, mostly), the JS line/column info is not useful anyway.... (But yes, sometimes it's been helpful.)

Right now I can't use the Gecko profiler as part of my normal browsing, because with near-certainty it will completely lock up my browser soon after startup with my normal set of tabs.  :(

Naveed, if we could get this fixed this would make it a lot easier to convince people to normally browse with the Gecko profiler turned on.

We should still fix this at some point.
