Check esr91 touch pipeline #1037

Closed rainemak closed 9 months ago

rainemak commented 9 months ago

There are multiple things to check as many could break it.

First thing to check is that touch events themselves are passes correctly to the gecko embedlite from qtmozembed.
Check plausible build time #ifdefs / out commented code related APZC (Async Pan Controller) & APZCTreeManager related code paths (events from EmbedLiteViewParent to EmbedLiteViewChild)
Check plausible fatal errors in embedlite-components
Active status of the content

Break this task down into smaller tasks once there's visibility towards them.

Fixed over here https://github.com/llewelld/gecko-dev/pull/4 https://github.com/llewelld/gecko-dev-mirror/pull/1

Enabling APZ and then fixing incorrectly initialized TimeStamps. TimeStamp that is initialized with default constructor will have timestamp value of zero. Without real timestamp (non-zero) values mozilla::layers::Axis reports always zero velocity. Thus, preventing mozilla::layers::AsyncPanZoomController to handle end of panning (AsyncPanZoomController::HandleEndOfPan) so that fling state would get triggered.
