commit 5975b62cd1f3f170bb82e9761efca40e5e5bfb16
Author: Rahul Ravikumar <rahulrav@google.com>
Date: Wed Jul 24 12:24:17 2019

TaskExecutor's background executor is now SerialExecutor.

* This gives us visibility into the number of pending tasks which will
be important in the next CL.

There is a race condition between the SerialExecutor draining its queue
of pending tasks and SystemAlarmDispatcher's onAllCommandsCompleted() callback.
This is because SystemAlarmDispatcher thinks there are no more things to be
done even though there are pending runnables in the SerialExecutor.
This CL makes this information available. In the next CL, CommandHandler
will check for pending runnables in the SerialExecutor queue.

* Fixed TestWorkManagerImpl to use Configuration#getTaskExecutor().
* Updated unit tests.

Test: Updated unit tests.

Ensure SerialExecutor has no more pending tasks.

* We need to ensure this is the case because we might shutdown
SystemAlarmService without actually completing all the tasks.

Test: Existing unit tests pass. Ran integration tests.

@ranjitkumar

Here is the verification steps for this bug.

Host Operating System: Windows 10

Set up: Disable ipv6 manually in Windows by referring to the link. To confirm that ipv6 is not in use, go to http://test-ipv4.com/ and make sure that ipv6 is not supported.

Repro step: 1, Create AVD with API 31 and wipe data before each run.

2, Run AVD and make sure it is cold boot.

3, Immediately after the device boot completes, go to Gmail or Google and try to load the Google Sign In page.

4, Google Sign In page should take more than 1 minute to load for the buggy version (32.3.10). Google Sign in page should take less than 20 seconds for the new version (with fix in CL to load.

Thanks for the steps Weilun.

When I tried to load the sign in page after disabling the ipV6 manually it takes more than 2 minutes for the sign in page to show up with stable Emulator 31.3.10.

I will verify the fix in the upcoming Emulator build.

ra...@google.com <ra...@google.com> #13Sep 13, 2022 09:51PM

Verified by ra...@google.com.

This bug has been verified as fixed with the latest Emulator build that is shared with QA.

It takes about 20 seconds for the Gmail sign in page to show up on AVD(Pixel_4a_API_31) with Emulator 31.3.11-9032202 using ipv4 in stand alone mode.

OS : Windows 10
