Fallout from bug 1407940?

No.. I think this is an issue following bug 1247189 http://searchfox.org/mozilla-central/rev/40b456626e2d0409b7034768b4d9526fc7235ea4/dom/media/mediasource/MediaSourceDemuxer.cpp#391 Can still access mManager, and it access mManager on the main thread. But we have mManager being cleared on the TaskQueue http://searchfox.org/mozilla-central/rev/40b456626e2d0409b7034768b4d9526fc7235ea4/dom/media/mediasource/MediaSourceDemuxer.cpp#217 So we have a race on MediaSourceTrackDemuxer::mManager member... it needs to be made thread safe.

Comment on attachment 8919161 [details] [diff] [review] Bug 1408987 - part1 : add assertion OnTaskQueue() to indicate the running thread for funcitons. Review of attachment 8919161 [details] [diff] [review]: ----------------------------------------------------------------- fix the spelling in the commit description (functions vs funcitons) I suggest: "Add OnTaskQueue() assertion to clarify functions' running thread" In any case, r- as the code will now assert if some functions are called after being detached/breakcycle while it would have handle the error softly before. You need to choose one behaviour over the other: either you assert if the functions are called after detached, or you reject the condition nicely. Don't do both... Asserting is likely fine. ::: dom/media/mediasource/MediaSourceDemuxer.cpp @@ +406,5 @@ > > RefPtr<MediaSourceTrackDemuxer::SeekPromise> > MediaSourceTrackDemuxer::DoSeek(const TimeUnit& aTime) > { > + MOZ_ASSERT(OnTaskQueue()); in the test below you check if the manager is detached, however now it will just assert. so if we want to handle failure softly, we can't assert. It should be one or the other, can't be both. and it's the same wherever you check for mManager

(In reply to Jean-Yves Avenard [:jya] from comment #5) > in the test below you check if the manager is detached, however now it will > just assert. I'll change the assertion to the place after we check whether the manager is detached.

this needs a security assessment first

Comment on attachment 8919185 [details] [diff] [review] Bug 1408987 - part1 : add OnTaskQueue() assertion to clarify functions' running thread. Doesn't need sec-approval since it's trunk-only. We'll obviously need to make sure this gets nominated as well if/when bug 1247189 gets nominated for Beta approval, however.
