Description Daniel Holbert [:dholbert] 2011-05-21 23:49:52 PDT
WARNING: Failed to create timer: file /scratch/work/builds/mozilla-central/mozilla-central.10-10-08.07-25/mozilla/dom/base/nsJSEnvironment.cpp, line 3387

1. Start debug build of firefox.
2. Quit.

At least 4 instances of this warning will be the last thing you see in your terminal output:
> WARNING: Failed to create timer: file mozilla/dom/base/nsJSEnvironment.cpp, line 3387

This affects both a just-created profile as well as profile that I've used for a bit.

Snippet of source that's involved here:
> 3376 void
> 3377 nsJSContext::PokeCC()
> 3378 {
> 3384   CallCreateInstance(";1", &sCCTimer);
> 3385 
> 3386   if (!sCCTimer) {
> 3387     NS_WARNING("Failed to create timer");
> 3388     return;
> 3389   }

I'm guessing the timer-creation is failing because we're in XPCOM shutdown...?
Comment 1 Daniel Holbert [:dholbert] 2011-05-21 23:52:22 PDT
The warning was added just a few months ago, actually.  Flagging as blocking the bug that added it, on the assumption that this has been happening since then.
Comment 2 Boris Zbarsky [:bz] (still a bit busy) 2011-05-23 10:48:08 PDT
Yeah, we should probably just remove the NS_WARNING.

Here's a patch to remove the warning (and replace it with an explanatory comment).

d'oh, I missed that there are two copies of this same warning -- one in PokeGC (fixed by already-checked-in-patch), and another one in PokeCC.

So, we still spam this on shutdown, from PokeCC.  Patch coming up to silence that one, too.
