Bug 1321418 - 1. Use GekcoBundle events in GeckoApp; r=snorp r=sebastian
Switch GeckoApp to using GeckoBundle events everywhere. UI or Gecko
events are used if the event requires the UI or Gecko thread,
respectively, and background events are used for all other events.
There are changes to some other Java classes, such as SnackbarBuilder
and GeckoAccessibility, due to the switch to GeckoBundle.
For "Snackbar:Show", we need the global EventDispatcher because the
event can be sent to both GeckoApp and GeckoPreferences. Howveer, we
only want one listener registered at the same time, so we register and
unregister in GeckoApp's and GeckoPreferences's onPause and onResume
methods.
Bug 1321418 - 2. Use appropriate JS EventDispatcher to send GeckoApp events; r=snorp r=sebastian
Change JS code that sends events to GeckoApp to use either the global
EventDispatcher or the per-window EventDispatcher.
"Session:StatePurged" is not used so it's removed. "Gecko:Ready" in
geckoview.js is not necessary because it's only used for GeckoApp, so
it's removed from geckoview.js.
Bug 1321418 - 3. Use GeckoBundle events in BrowserApp; r=snorp r=sebastian
Switch BrowserApp to using GeckoBundle events, in a similar vein as
GeckoApp. UI or Gecko events are used if the event handlers required UI
or Gecko thread, respectively, and background events are used for all
other events.
Some other Java classes also have to be modified as a result of
switching to GeckoBundle.
Bug 1321418 - 4. Use global EventDispatcher to send BrowserApp events; r=snorp r=sebastian
Change JS code that sends events to BrowserApp to use the global
EventDispatcher instead of "Messaging".
Bug 1321418 - 5. Update usages of events in tests; r=gbrown
Update cases where we use or wait for events in tests.
This patch is written with the help of the following script.
function rename() {
find .\
-type f\
! -path "./obj*"\
! -path "./.git"\
! -path "./.hg"\
\( -name "*.cpp" -or\
-name "*.h" \)\
-exec sed -i -e "s/$1/$2/g" "{}" \;
}
rename "css::Side" "Side"

This puts events in the queue instead of the event tree, and then fires them
based on the queue. Some tests need to be adjusted to make sure they check
constraints on event order correctly.
Since we will fire events in the correct order we can use the index of the
event target at the time the event is fired. This protects from weird cases
where the target is inserted, and then children before the target are removed.

This ensures that if creating the sub tree creates events to fire they will go
before the show event for the root of the tree. It is fine to fire show events
for the subtree before the root because they will just get coalesced away
anyway. However it is important that any hide events come before the hidden
subtree appears in the new tree.
Mutation events are kept in a queue before firing. The queue is only
coalesced when necessary, at present this is when queueing a hide event, or
just before firing all the events. It may be possible to do without the
former, but that is left as future work. The state of what types of events an
accessible is a target of is stored in the accessible. Combining that with a
map from accessible and type pairs to events we can quickly remove unnecessary
events from the queue when we need to coalesce.
