Anssi Kääriäinen 584e2c0337 Prevent Oracle from changing field.null to True ... Fixed #17957 -- when using Oracle and character fields, the fields were set null = True to ease the handling of empty strings. This caused problems when using multiple databases from different vendors, or when the character field happened to be also a primary key. The handling was changed so that NOT NULL is not emitted on Oracle even if field.null = False, and field.null is not touched otherwise. Thanks to bhuztez for the report, ramiro for triaging & comments, ikelly for the patch and alex for reviewing.		2012-04-29 19:25:46 +03:00

__init__.py	Fixed #17258 -- Moved `threading.local` from `DatabaseWrapper` to the `django.db.connections` dictionary. This allows connections to be explicitly shared between multiple threads and is particularly useful for enabling the sharing of in-memory SQLite connections. Many thanks to Anssi Kääriäinen for the excellent suggestions and feedback, and to Alex Gaynor for the reviews. Refs #2879.	2011-12-16 13:40:19 +00:00
