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/dialects/postgresql/__init__.py | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'lib/sqlalchemy/dialects/postgresql/__init__.py') diff --git a/lib/sqlalchemy/dialects/postgresql/__init__.py b/lib/sqlalchemy/dialects/postgresql/__init__.py index 06d22872a..2762a9971 100644 --- a/lib/sqlalchemy/dialects/postgresql/__init__.py +++ b/lib/sqlalchemy/dialects/postgresql/__init__.py @@ -4,7 +4,6 @@ # # This module is part of SQLAlchemy and is released under # the MIT License: http://www.opensource.org/licenses/mit-license.php - from . import base from . import pg8000 # noqa from . import psycopg2 # noqa @@ -58,7 +57,10 @@ from .ranges import INT8RANGE from .ranges import NUMRANGE from .ranges import TSRANGE from .ranges import TSTZRANGE +from ...util import compat +if compat.py3k: + from . import asyncpg # noqa base.dialect = dialect = psycopg2.dialect -- cgit v1.2.1
