2022-05-13Added backward compatibility test for ConnectionHandler.databases property.Nick Pope
The ConnectionHandler.databases property is no longer used within Django, but it is maintained for backward compatibility with 3rd party packages that have used this private API in the past.

Follow up to 944469939b9eb93fda0924f78faba5c0ffae2dff.
2021-01-04Simplified django.db.utils.load_backend().William Schwartz
Previously load_backend() performed search by computing the (sole) entry of django.db.backends.__path__ manually from django.db.utils.__file__. Now django.db.backends.__path__ is used directly.

2015-12-03Fixed #25761 -- Added __cause__.__traceback__ to reraised exceptions.Raphaël Hertzog
When Django reraises an exception, it sets the __cause__ attribute even in Python 2, mimicking Python's 3 behavior for "raise Foo from Bar". However, Python 3 also ensures that all exceptions have a __traceback__ attribute and thus the "traceback2" Python 2 module (backport of Python 3's "traceback" module) relies on the fact that whenever you have a __cause__ attribute, the recorded exception also has a __traceback__ attribute. This is breaking testtools which is using traceback2 (see https://github.com/testing-cabal/testtools/issues/162). This commit fixes this inconsistency by ensuring that Django sets the __traceback__ attribute on any exception stored in a __cause__ attribute of a reraised exception.

2015-06-15Fixed #24979 -- Removed usage of inspect.getargspec().Tim Graham
2015-06-15Fixed flake8 warnings on Python 3.Tim Graham
2015-05-17Fixed #23820 -- Supported per-database time zone.Aymeric Augustin
The primary use case is to interact with a third-party database (not primarily managed by Django) that doesn't support time zones and where datetimes are stored in local time when USE_TZ is True. Configuring a PostgreSQL database with the TIME_ZONE option while USE_TZ is False used to result in silent data corruption. Now this is an error.
2015-03-25Fixed #24394 -- Allowed running tests with empty default dictionary.Andrei Kulakov
2015-02-20Fixed #24351, #24346 -- Changed the signature of allow_migrate().Loic Bistuer
The new signature enables better support for routing RunPython and RunSQL operations, especially w.r.t. reusable and third-party apps. This commit also takes advantage of the deprecation cycle for the old signature to remove the backward incompatibility introduced in #22583; RunPython and RunSQL won't call allow_migrate() when when the router has the old signature. Thanks Aymeric Augustin and Tim Graham for helping shape up the patch. Refs 22583.
