* Remove dependencies on keepalive from StremaOutput and stream_worker
Pull logic from StreamOutput and stream_worker into the Stream
class, unifying keepalive and idle timeout logic. This prepares
for future changes to preserve hls state across stream url changes.
* Unmark tests as flaky (though still flaky)
This put tests into the broken state where they are flaky and do not yet pass
* Fix bug in test_hls_stream with incorrect path
* Enable and de-flake HLS stream tests
Background: Tests encode a fake video them start a stream to be decoded. Test
assert on the decoded segments, however there is a race with the stream worker
which can finish decoding first, and end the stream which ereases all buffers.
Breadown of fixes:
- Fix the race conditions by adding synchronization points right before the
stream is finalized.
- Refactor StreamOutput.put so that a patch() can block the worker
thread. Previously, the put call would happen in the event loop which was
not safe to block. This is a bit of a hack, but it is the simplist possible
code change to add this synchronization and arguably provides slightly better
separation of responsibilities from the worker anyway.
- Fix bugs in the tests that make them not pass, likely due to changes
introduced while the tests were disabled
- Fix case where the HLS stream view recv() call returns None, indicating
the worker finished while the request was waiting.
The tests were previously failing anywhere from 2-5% of the time on a lightly
loaded machine doing 1k iterations. Now, have 0% flake rate. Tested with:
$ py.test --count=1000 tests/components/strema/test_hls.py
