2019-09-09Refs #29444 -- Allowed returning multiple fields from INSERT statements on ↵Johannes Hoppe
PostgreSQL. Thanks Florian Apolloner, Tim Graham, Simon Charette, Nick Pope, and Mariusz Felisiak for reviews.
2019-08-29Fixed #25367 -- Allowed boolean expressions in QuerySet.filter() and exclude().Matthew Schinckel
This allows using expressions that have an output_field that is a BooleanField to be used directly in a queryset filters, or in the When() clauses of a Case() expression. Thanks Josh Smeaton, Tim Graham, Simon Charette, Mariusz Felisiak, and Adam Johnson for reviews. Co-Authored-By: NyanKiyoshi <hello@vanille.bid>

operations for PostgreSQL. Thanks to Simon Charettes for review. Co-Authored-By: Daniel Tao <daniel.tao@gmail.com>
2019-08-20Fixed #29979, Refs #17337 -- Extracted AutoField field logic into a mixin ↵Nick Pope
and refactored AutoFields. This reduces duplication by allowing AutoField, BigAutoField and SmallAutoField to inherit from IntegerField, BigIntegerField and SmallIntegerField respectively. Doing so also allows for enabling the max_length warning check and minimum/maximum value validation for auto fields, as well as providing a mixin that can be used for other possible future auto field types such as a theoretical UUIDAutoField.
2019-08-13Refs #25367 -- Moved Oracle Exists() handling to contextual methods.Simon Charette
Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in the following cases. 1. When part of a SELECT clause. 2. When part of a ORDER BY clause. 3. When compared against another expression in the WHERE clause. This commit moves the systematic CASE WHEN wrapping of Exists.as_oracle to contextual .select_format, Lookup.as_oracle, and OrderBy.as_oracle methods in order to avoid unnecessary wrapping.

values on Oracle. This is currently not actively used, since the ORM will ask the SQL compiler to only return auto fields.
2019-07-02Fixed typos in comments and docs.Min ho Kim
2019-06-20Fixed #30451 -- Added ASGI handler and coroutine-safety.Andrew Godwin
This adds an ASGI handler, asgi.py file for the default project layout, a few async utilities and adds async-safety to many parts of Django.
2019-05-08Used time.monotonic() instead of time.time() where applicable.Przemysław Suliga
time.monotonic() available from Python 3.3: - Nicely communicates a narrow intent of "get a local system monotonic clock time" instead of possible "get a not necessarily accurate Unix time stamp because it needs to be communicated to outside of this process/machine" when time.time() is used. - Its result isn't affected by the system clock updates. There are two classes of time.time() uses changed to time.monotonic() by this change: - measuring time taken to run some code. - setting and checking a "close_at" threshold for for persistent db connections (django/db/backends/base/base.py).

2019-02-13Fixed #30184 -- Removed ellipsis characters from shell output strings.Dan Davis
