* Repair async test refactorMike Bayer2021-01-021-0/+5
| | | | | | | | | | | | | | | in I4940d184a4dc790782fcddfb9873af3cca844398 we reworked how async tests run but apparently the async tests in test/ext/asyncio are reporting success without being run. This patch pushes pytestplugin further so that it won't instrument any test or function overall that declares itself async. This removes the need for the __async_wrap__ flag and also allows us to use a more strict "run_async_test" function that always runs the asyncio event loop from the top. Also start working asyncio into main testing suite. Change-Id: If7144e951a9db67eb7ea73b377f81c4440d39819

* Detect non compatible execution in async modeFederico Caselli2020-12-081-14/+0
| | | | | | | | | | The SQLAlchemy async mode now detects and raises an informative error when an non asyncio compatible :term:`DBAPI` is used. Using a standard ``DBAPI`` with async SQLAlchemy will cause it to block like any sync call, interrupting the executing asyncio loop. Change-Id: I9aed87dc1b0df53e8cb2109495237038aa2cb2d4
* Implement rudimentary asyncio support w/ asyncpgMike Bayer2020-08-131-0/+14
Using the approach introduced at https://gist.github.com/zzzeek/6287e28054d3baddc07fa21a7227904e We can now create asyncio endpoints that are then handled in "implicit IO" form within the majority of the Core internals. Then coroutines are re-exposed at the point at which we call into asyncpg methods. Patch includes: * asyncpg dialect * asyncio package * engine, result, ORM session classes * new test fixtures, tests * some work with pep-484 and a short plugin for the pyannotate package, which seems to have so-so results Change-Id: Idbcc0eff72c4cad572914acdd6f40ddb1aef1a7d Fixes: #3414
