I've got a WebGL demo that texture-maps an Ogg video onto the faces of a rotating cube. It's using a ton of memory (I believe there's a memory leak somewhere), but the issue at hand for the purposes of this bug is that it's crashing, apparently in GC.

Could the crash be related to the leaking, or some rooting issue?
It's possible, although even if the script is leaking, Firefox shouldn't be crashing while trying to perform GC. However, looking at the script, I see no obvious sign of leaks.

However, looking at the script, I see no > obvious sign of leaks. Ok. When I was referring to leaks or rooting bugs, I guess I meant in whatever C++ underlies the WebGL feature. I don't know much about it. This could be pretty valuable because we are getting a good number of GC crashes in the wild but we don't know how to repro them. Dumb question: how do I run your test? I loaded your link in a new TM build and I got a dialog "Unable to initialize WebGL. Your browser may not support it."
Oh, I should have included that. Set the preference "webgl.enabled_for_all_sites" to true in trunk builds.
My guess is that yes, the underlying WebGL code is leaking memory, resulting in the crash.
I'm continuing to do some work to try to isolate this... memory is clearly leaking during the call to gl.texImage2d to copy the latest frame of video into the texture. Looks like the problem may just be that new image objects are getting created for each frame of video copied into the texture buffer, and they're stacking up fast. But GC shouldn't be crashing trying to dispose of them either. Still investigating what's going on but obviously some insight would be helpful.
If I set flipY to false when calling texImage2D, the leak goes away. Looks like the temporary surface created to flip the texture is being leaked. Trying a fix now.
The code that handles flipping was replacing the surface with the flipped version without releasing the original surface; this patch adds a single NS_RELEASE to free the original surface; now instead of sucking up about a gigabyte per minute of memory without releasing it, my demo only uses about 100 MB of additional memory by the time it's done running, thanks to GC actually working to free no-longer-used blocks.

Did your investigation reveal why the GC was crashing? We get crashes like this in the field pretty often but have very little data on them.
No idea why GC was crashing here; the memory being leaked is definitely being allocated in C++ though... is it possible GC could crash if memory is crazy full but there's not actually anything to collect?

When the crash happens, is cycle collector related code always on the stack?
OK, I misread the original crash log; actually it's the ogg decoder crashing because it's failing to allocate memory because it's packed full. So I originally filed this in the wrong place. I think my patch fixes this problem.
Ugh, this is awfulness related to not using COMPtr here. This is actually already fixed by code in bug 533663. I'm getting ready to land that very soon, so let's wait until that's fixed?
Sounds like a plan.
Should we close this bug? Not sure what to do at this point; there is a crash, and it's being caused by this leak, but not sure if we want to assign this back to someone else to try to figure out more.
Nope, the bug is still valid, I'll mark it as depending on bug 533663 -- I'll be landing that today most likely, will ping you to retest when that happens.
Depends on: 533663
The dep bug is checked in -- can you try this again in the latest nightly?
After this checkin, I'm getting a "not enough arguments" exception on this line, which I never did before: gl.texImage2D(gl.TEXTURE_2D, 0, videoElement, true); This should be valid, however, as the last argument is the optional asPremultipliedAlpha option. Error: uncaught exception: [Exception... "Not enough arguments" nsresult: "0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)" location: "JS frame :: https://developer.mozilla.org/samples/webgl/sample8/webgl-demo.js :: updateTexture :: line 286" data: no]
I did a trunk build using the fix from 542336 and memory use is much, much better, although for the duration of the demo, memory use still climbs by about 3 MB per second for the duration of the demo. Previously, it was climbing by as much as 15 MB per second. However, if I change flipY to false, the memory use only climbs half as fast. This may however be normal for the way our GC works, in which case this is fixed. Certainly, the demo plays through smoothly and Firefox no longer crashes before the end now, which is a win.
Sounds like a followup bug is in order. Vlad, what do you think? /be
Yeah, we should at least understand why the memory is climbing, as I don't think it should be. (Also, you shuold be able to get away from using flipY if you just invert your y-axis texcoords :-)
Yeah, I know, but as it turns out, the way I did it is useful information for debugging, no? :)
Has the follow-up bug been filed, or should I do so?
That sample is still causing Firefox to hold on to a lot of memory, even after I've closed the tab running the sample.
Does that memory usage persist, or does it get freed after a bit? (Up to a minute or so)
It seems to stick.
This memory leak was recently fixed: bug 572018. Given that the leak was happening exactly in the situtation that you describe here, in the flipping of the image in gl.texImage2D(gl.TEXTURE_2D, 0, videoElement, true); I am very hopeful that this was the same leak. Can you retry and confirm?
Yes, definitely fixed. Yay!
