Smooth out iOS irregular input events delivery #11817

liyuqian · 2019-09-01T20:08:00Z

This patch is a lower level implementation of
flutter/flutter#36616 that would only impact iOS
engine, and host unittests.

Fixes flutter/flutter#31086 This patch is a lower level implementation of flutter/flutter#36616 that would only impact iOS engine, and host unittests.

I am still reviewing the patch but the immediate feedback is that we don't patch "shell/common" classes with platform specific behavior. Please move the same to PlatformView<Foo>

shell/common/engine.cc

+    uint64_t trace_flow_id) {
  TRACE_EVENT0("flutter", "Engine::DispatchPointerDataPacket");
  TRACE_FLOW_STEP("flutter", "PointerEvent", trace_flow_id);
+#ifdef ENABLE_IRREGULAR_INPUT_DELIVERY_FIX


Please perform this sanitization on the platform task runner and in the platform specific subclass for the entrypoint of these events into the engine. In this case, it would be PlatformViewIOS. We don't apply platform specific hacks in the "common" classes. This will also get rid of the the ENABLE_IRREGULAR_INPUT_DELIVERY_FIX.

shell/common/shell_test.h

+  //
+  // The test here is insensitive to the choice of time unit as long as
+  // delivery_time and frame_time are in the same unit.
+  void TestSimulatedInputEvents(int num_events,


This test utility can be moved into the TU that defines the test itself and out of the fixture.

chinmaygarde · 2019-09-03T22:32:46Z

We had a conversation offline to rework this so that platform specific stuff doesn't end up in the common classes but is also tested on all platforms.

And let the PlatforView decide which PointerDataDispatcher is used.

liyuqian · 2019-09-04T21:45:40Z

@chinmaygarde : this is ready for review again.

Getting closer. Just a few more nits. Thanks.

+  pointer_data_dispatcher_ =
+      platform_view.MakePointerDataDispatcher(*animator_, *runtime_controller_);


Platform view methods can only be accessed on the platform task runner. Maybe create the dispatcher in the Shell::Create call on the platform task runner and pass the same to the engine in the constructor? You could then set the animator and the the runtime controller on the dispatcher if one is provided here. The dispatcher can be a thread safe object.

Done. I sent in a std::function<std::unique_ptr<PointerDataDispatcher>(...)> instead of a PointerDataDispatcher because Animator& and RuntimeController& must be initialized at construction.

Please document this classes in the doxygen format. See shell.h for an example. Please be sure to document the threading restrictions and lifecycle of these objects.

Thanks for the concise description. Please put these in doxygen format though so these end up being searchable in the docs for the test.

I realize the units dont matter, but can you make these be points anyway? Makes this clearer to read than just an int.

Did you forget to push this? I still see these as ints. In any case, it was a nit.

Ah, I probably misunderstood your previous comment and only added a comment. Now I've used UnitlessTime to make it more clear.

+  // (16.67ms for 60Hz).
+  constexpr int n = 47;
+  constexpr double iphone_xs_times[n] = {0.15,


You can get rid of n = 47 and instead write sizeof(iphonx_xs_times) / sizeof(double) or arraysize. That way, we can add and remove items from this fixture without potentially forgetting to update the size. These are known at compile time anyway.

The documentation you added inline in the implementation of the DispatchPacket can be added here instead in doxygen format to clarify the purpose if this class. Also, maybe a more descriptive name for this class would be better. One that describes what this class does and not where this class is used.

What has clang-format done to my headers... Thank you for being smarter than clang-format! 😄

If you correctly indent the second line, it matches the indentation correctly for all following lines. If the first line overflows, then stuff gets weird.
