Bug 1362000 - Regenerate mask layer when the boundary of the masked element changed. r=mstange a=jcristau [1] https://hg.mozilla.org/mozilla-central/file/2bc714f86791/layout/painting/FrameLayerBuilder.cpp#l3887 MozReview-Commit-ID: 7lUKTMYPFXo

Bug 1358073 - Call constructors when creating and copying scope data. r=shu a=jcristau

Bug 1350301 - Fix broken layout of dominator view with callstacks enabled; r=fitzgen a=jcristau The shared Frame component appears to set the containing element to be a flex component, while the table view with the dominators expects an inline-block element. This appears to have been broken for quite some time with Bug 1251033. MozReview-Commit-ID: CYkps6QfTJc

Bug 1350279 - try other codecs when first one failed to create. r=esawin a=gchang Video fails to play on Sony Z3C when the media server is in a state that no hardware codec can be created unless reboot. Fallback to software codec when that happens to workaround the issue. MozReview-Commit-ID: AaRIw7KPaF3

Bug 1347476 - [RTL] Update TouchDelegate Rect for tab close button relatively, r=sebastian a=jcristau MozReview-Commit-ID: 2ptzHWBVvUq

Bug 1341992 - Only do hit-testing with the ignore-root-scroll-frame flag on zoomable platforms. r=tnikkel a=jcristau The ignore-root-scroll-frame flag is generally needed on Fennec, or possibly other zoom-enabled platforms, when we have them. It allows hit-testing things outside the main thread's notion of what is visible, because that might occur when the user zooms out. For largely historical reasons, we are passing this flag around in other scenarios, such as when doing hit-tests for touch events, because in the past touch events and zooming only happened on Fennec, so it didn't matter. Now that we have touch events enabled on other platforms, such as Windows, we need to make the distinction clearer. MozReview-Commit-ID: BlHjtjFYgzv

Bug 1336254 - Use http://no-ssl.mozqa.com to access test pages on mozqa.com without SSL. r=maja_zf a=test-only All connections to mozqa.com which do not use SSL have to be done to a unique subdomain. This was requested to lower the amount of active HTTP endpoints. MozReview-Commit-ID: JAFjQFhTCxT

Bug 1300590 - Implement support for $0 and inspect bindings in devtools.inspectedWindow.eval. MozReview-Commit-ID: CHuc57tfgzo

Bug 1363428 - Add per-test-queue metadata to wptrunner, r=maja_zf This adds a metadata object associated with each test queue, and uses it to pass cache information into the marionette internal reftest implementation so that we are able to cache only those canvases that will be reused. MozReview-Commit-ID: zASrlvnri3

Bug 1363428 - Switch wptrunner to use a deque for test groups, r=maja_zf, jdm Initially wptrunner had a single test queue that was shared between all processes. Then for --run-by-dir it changed to a queue of queues. This change makes it a queue of deques, which is simpler, since the test queues themselves are no longer shared between processes. It also changes the implementation when we aren't using --run-by-dir but are using multiple processes to pre-group the tests into N queues rather than sharing a single queue between all processes. This is necessary to use the deque of course, but importantly anticipates a change in which we will pre-compute per queue metdata for each queue; that doesn't work well with one shared queue. The downside of this change is that there is no work stealing, so it may be less efficient if we randomly assign many slow jobs to one particular process. MozReview-Commit-ID: 7e0Odk7yDwr
