Fix a previously undetected ``trio``-``asyncio`` task lifetime linking
|
||
|
|
issue with the ``to_asyncio.open_channel_from()`` api where both sides
|
||
|
|
where not properly waiting/signalling termination and it was possible
|
||
|
|
for ``asyncio``-side errors to not propagate due to a race condition.
|
||
|
|
|
||
|
|
The implementation fix summary is:
|
||
|
|
- add state to signal the end of the ``trio`` side task to be
|
||
|
|
read by the ``asyncio`` side and always cancel any ongoing
|
||
|
|
task in such cases.
|
||
|
|
- always wait on the ``asyncio`` task termination from the ``trio``
|
||
|
|
side on error before maybe raising said error.
|
||
|
|
- always close the ``trio`` mem chan on exit to ensure the other
|
||
|
|
side can detect it and follow.
