Bug 1424922 - Prevent calling PDFiumParent::Close twice. r=dvander We call PDFiumParent::Close twice under certain conditions. Once in PDFiumProcessParent::Delete, and once in PDFiumProcessParent's dtor. So we may hit MOZ_ABORT which tell us that we are trying to close a closed channel. This patch prevents hitting this abort by: 1. Only close the channel in PDFiumProcessParent::Delete, remove another call in PDFiumProcessParent's dtor. (Please see the change in PDFiumProcessParent.cpp). 2. Remove PDFiumParent::AbortConversion and relative code. We can just use PDFiumParent::EndConversion instead. When calling PDFiumParent::Close, we actually close the IPC channel *synchronously*, which means there is no need to register a callback by PDFiumParent::AbortConversion to receive actor-destroy callback.

Remove `layers.omtp.force-sync` preference (bug 1416941, r=dvander) This commit removes the `layers.omtp.force-sync` preference and replaces it with a preprocessor define that is commented out. This commit also changes the behavior of force-sync so that it also does synchronization with CompositorBridgeChild like normal OMTP. This simplifies the code and makes using a preprocessor define easier. MozReview-Commit-ID: 6RfuFTFBdMh

Bug 1413011 - Allow the UI/chrome process to shutdown if the compositor thread failed to start. r=dvander There are up to two compositor threads spawned - one in the GPU process and one in the UI/chrome process. If the GPU process is used, then failing to start the UI compositor thread is not fatal -- unless the GPU process crashes too much and we fallback to the UI/chrome process. If the GPU process compositor thread failed to start, then the GPU process will crash and either restart, or fallback to the UI/chrome process thread. If both fail, then Firefox crashes as expected. Before we would not setup a content process properly unless the UI compositor thread was active, even when using the GPU process. Now we do, which allows the browser to be fully functional. Additionally when shutting down, we ignore the lack of a compositor thread to permit a graceful shutdown. In a future patch we will ideally we would not spawn the compositor thread in a process until we actually need it, and release assert on its failing to start.

Bug 1409176 - make SyncObjectD3D11Client become fallible. r=dvander Currently, the device-reset flow doesn't notify the decoder for device change immediately. The decoder might use an invalid sync-object for synchronization. Then, we will hit some assertions. This patch try to make the synchronization flow become fallible, then we could pass the error to the media framework for error handling. MozReview-Commit-ID: BFY32MmOdt0

Track when we start and finish painting a layer transaction. (bug 1412951, r=dvander) This commit adds instrumentation and some asserting to track a "paint group", which is essentially the first PaintThread::AsyncPaintContents until PaintThread::AsyncEndLayerTransaction. I didn't add an AsyncBeginLayerTransaction and use that to start a "paint group" as I think it makes sense to not have a paint marker if we don't do any painting. MozReview-Commit-ID: AlSsUUF5ZOH

Be sure to call EndLayerTransaction if there are queued paints. (bug 1412951, r=dvander) I believe this is the only case where we miss calling EndLayerTransaction, but still had queued async paints. This wasn't an issue before, because the following transaction would then do the synchronization. But I'd like to use EndLayerTransaction for a profiler mark, so we should call it unconditionally.

Fix PrepareDrawTargetForPainting (bug 1409871 part 16, r=dvander) CapturedPaintState::mTarget is actually a dual draw target to the black and white draw targets, so this code will have the white draw target cleared black and then white.

Bug 1399453 - Temporarily annotate crash reports with compositor thread owners. r=dvander From the crashes associated with bug 1389021, we know that some compositor thread IPDL owners are not being cleaned up properly. We do not know which protocols are causing the problem, so we temporarily will annotate the logs with the ownership status. This should be limited to under a dozen instances of the protocols. This change will be backed out after a few builds are produced with it and we see the first crash reports with the relevant data.
