+ // scrollBy call would move the animation destination a little bit, and so
+ // the loop would continue advancing the scroll position. The bug resulted

+ // What we want here is to synthesize all of the touch events (from this code in
+ // the child process), and have the chrome process generate and process them,
+ // but not allow the events to be dispatched back into the child process until
+ // later. This allows us to ensure that the APZ in the chrome process is not
+ // waiting for the child process to send notifications upon processing the
+ // events. If it were doing so, the APZ would block and this test would fail.
+
+ // In order to actually implement this, we call the synthesize functions with
+ // a async callback in between. The synthesize functions just queue up a
+ // runnable on the child process main thread and return immediately, so with
+ // the async callbacks, the child process main thread queue looks like
+ // this after we're done setting it up:
+ // synthesizeTouchStart
+ // callback testDriver
+ // synthesizeTouchMove
+ // callback testDriver
+ // ...
+ // synthesizeTouchEnd
+ // callback testDriver
+ //
+ // If, after setting up this queue, we yield once, the first synthesization and
+ // callback will run - this will send a synthesization message to the chrome
+ // process, and return control back to us right away. When the chrome process
+ // processes with the synthesized event, it will dispatch the DOM touch event
+ // back to the child process over IPC, which will go into the end of the child
+ // process main thread queue, like so:
+ // synthesizeTouchStart (done)
+ // invoke testDriver (done)
+ // synthesizeTouchMove
+ // invoke testDriver
+ // ...
+ // synthesizeTouchEnd
+ // invoke testDriver
+ // handle DOM touchstart <-- touchstart goes at end of queue
+ //
+ // As we continue yielding one at a time, the synthesizations run, and the
+ // touch events get added to the end of the queue. As we yield, we take
+ // snapshots in the chrome process, to make sure that the APZ has started
+ // scrolling even though we know we haven't yet processed the DOM touch events
+ // in the child process yet.
+ //
+ // Note that the "async callback" we use here is SpecialPowers.tm.dispatchToMainThread
+ // with priority = input, because nothing else does exactly what we want:
+ // - setTimeout(..., 0) does not maintain ordering, because it respects the
+ // time delta provided (i.e. the callback can jump the queue to meet its
+ // deadline).
+ // - SpecialPowers.spinEventLoop and SpecialPowers.executeAfterFlushingMessageQueue
+ // are not e10s friendly, and can get arbitrarily delayed due to IPC
+ // round-trip time.
+ // - SimpleTest.executeSoon has a codepath that delegates to setTimeout, so
+ // is less reliable if it ever decides to switch to that codepath.
+ // - SpecialPowers.executeSoon dispatches a task to main thread. However,
+ // normal runnables may be preempted by input events and be executed in an
+ // unexpected order.
+
+ // The other problem we need to deal with is the asynchronicity in the chrome
+ // process. That is, we might request a snapshot before the chrome process has
+ // actually synthesized the event and processed it. To guard against this, we
+ // register a thing in the chrome process that counts the touch events that
+ // have been dispatched, and poll that thing synchronously in order to make
+ // sure we only snapshot after the event in question has been processed.
+ // That's what the chromeTouchEventCounter business is all about. The sync
+ // polling looks bad but in practice only ends up needing to poll once or
+ // twice before the condition is satisfied, and as an extra precaution we add
+ // a time guard so it fails after 10s of polling.
