* Name the platform thread in the timeline. This does not affect (nor is it affected by) the pthread name set by the embedder.
* Make it easier in the timeline to see not only when the frame was request, but also when that frame request was fulfilled.
* Trace message loop wakes.
* Perform all iOS logging through ASL
As of iOS 10, ASL is deprecated and replaced with os_log. ASL calls
continue to result in logging but as of iOS 10.3, only ASL_LOG_NOTICE
level and above are logged.
This change partially reverts d67972d649157582358876f90a99577cb3708e82,
adding back stdout and stderr redirection, which resulted in loss of
some direct writes to stdout that were necessary for debugging.
This change replaces the direct use of syslog with ASL on iOS, which
Apple has stated will continue to log on iOS >= 10. This eliminates the
need for the previous fwd-declaration of syslog.
ASL is deprecated and replaced by os_log() on iOS. As of iOS 10.3,
calling this function breaks our logging altogether. os_log isn't
available pre-iOS 10.0. Rather than implement version checks and
conditional logic, this change eliminates the existing redirection
altogether. All engine code should be logging via the syslog redirection
implemented in Logger_PrintString in dart_runtime_hooks.cc.
Since stdio redirection is eliminated, we eliminate the flag that
controls whether such redirection is enabled.
The PlatformView superclass constructor was posting a task to the UI thread
that adds the view to the shell's global list. This could result in UI thread
operations seeing PlatformView instances that are not fully constructed and do
not yet have an engine.
This was happening in https://github.com/flutter/flutter/issues/7735
The GPUSurfaceGL holds references to Skia objects that may own GL objects.
If the GL objects are destructed on the GPU thread after the EGL context has been
dropped, then the GL delete calls will not take effect.
* This allows the tests to add their own FLX files but still use consistent fonts.
* The test fonts are only embedded on the desktop test shells. The option is not available on mobile platforms.
* Right now, all fonts will resolve to the test font. If we want tests to be able to use the fonts they embed in FLX files but use the test font for platform fallbacks, we will need to add font selector fallbacks. I can do this in an another patch. So far, there are no users of this functionality.
* Update Skia revision to pull in GL native interface construction fixes on iOS.
Fixed in https://skia-review.googlesource.com/c/5212/
* Use the new image encoder API from Skia.
We push a bit up the tree during preroll to learn whether there system
composited layers below each layer. During update scene, we squash down
to paint tasks, which we execute after publishing the new scene.
