From 5fb0138a3220161703e6ab1087319a669d14e7f4 Mon Sep 17 00:00:00 2001 From: Mike Bayer Date: Sat, 4 Jul 2020 12:21:36 -0400 Subject: Implement rudimentary asyncio support w/ asyncpg 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 --- lib/sqlalchemy/util/__init__.py | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'lib/sqlalchemy/util/__init__.py') diff --git a/lib/sqlalchemy/util/__init__.py b/lib/sqlalchemy/util/__init__.py index ce9602745..1e3eb9a29 100644 --- a/lib/sqlalchemy/util/__init__.py +++ b/lib/sqlalchemy/util/__init__.py @@ -90,6 +90,10 @@ from .compat import unquote_plus # noqa from .compat import win32 # noqa from .compat import with_metaclass # noqa from .compat import zip_longest # noqa +from .concurrency import asyncio # noqa +from .concurrency import await_fallback # noqa +from .concurrency import await_only # noqa +from .concurrency import greenlet_spawn # noqa from .deprecations import deprecated # noqa from .deprecations import deprecated_20 # noqa from .deprecations import deprecated_20_cls # noqa -- cgit v1.2.1
