1167319 - Intermittently unable to record performance profile or close DevTools

Status: RESOLVED INVALID

(DevTools :: Performance Tools (Profiler/Timeline), defect, P1)

Description

[Dan Callahan [:callahad]]

I haven't figured out reliable STR's yet, but on several occasions over the past month (spanning Nightly 40 through 41), the record profile buttons (both the small toolbar icon and the larger one inside the panel) stop working.

Clicking them several times does nothing. The DevTools close button also does nothing. Switching between tools works.

The last time this happened I was using the May 19th nightly and saw the following spew in the console:

onPacket threw an exception: Error: Server did not specify an actor, dropping packet: {"error":"unknownError","message":"error occurred while processing 'startProfiler: [Exception... \"Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIProfiler.StartProfiler]\"  nsresult: \"0x80040111 (NS_ERROR_NOT_AVAILABLE)\"  location: \"JS frame :: resource://gre/modules/commonjs/toolkit/loader.js -> resource://gre/modules/devtools/server/actors/profiler.js :: ProfilerActor.prototype.onStartProfiler :: line 102\"  data: no]\nStack: ProfilerActor.prototype.onStartProfiler@resource://gre/modules/commonjs/toolkit/loader.js -> resource://gre/modules/devtools/server/actors/profiler.js:102:1\nDSC_onPacket@resource://gre/modules/commonjs/toolkit/loader.js -> resource://gre/modules/devtools/server/main.js:1456:15\nChildDebuggerTransport.prototype.receiveMessage@resource://gre/modules/commonjs/toolkit/loader.js -> resource://gre/modules/devtools/transport/transport.js:734:5\nLine: 102, column: 0"}

I've ran into something similar, although no error messages, and seems to kill the entire child process and hoped it was just my own build, ugh

This seems to be ok now.
