Claude Paroz d1c2e6dd04 Refs #28428 -- Made FileField.upload_to support pathlib.Path. 2019-08-18 20:34:58 +02:00
Simon Charette 8b4a43dda7 Fixed #29545 -- Fixed using filter lookups againts nested subquery expressions.
Made sql.Where resolve lhs of its child nodes. This is necessary to
allow filter lookups against nested subquery expressions to properly
resolve their OuterRefs to Cols.

Thanks Oskar Persson for the simplified test case.

Simon Charette efa1908f66 Refs #25367 -- Moved Oracle Exists() handling to contextual methods.
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.

Étienne Beaulé 4b6dfe1622 Fixed #30542 -- Fixed crash of numerical aggregations with filter.
Filters in annotations crashed when used with numerical-type
aggregations (i.e. Avg, StdDev, and Variance). This was caused as the
source expressions no not necessarily have an output_field (such as the
filter field), which lead to an AttributeError: 'WhereNode' object has
no attribute output_field.

Przemysław Suliga af5ec222cc Used time.monotonic() instead of time.time() where applicable.
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).

Rob 6b736dd074 Fixed #30349 -- Fixed QuerySet.exclude() on FilteredRelation.
Using annotated FilteredRelations raised a FieldError when coupled with
exclude(). This is due to not passing filtered relation fields to the
subquery created in split_exclude(). We fixed this issue by passing the
filtered relation data to the newly created subquery.

Secondly, in the case where an INNER JOIN is used in the excluded
subquery, the ORM would trim the filtered relation INNER JOIN in attempt
to simplify the query. This will also remove the ON clause filters
generated by the FilteredRelation. We added logic to not trim the INNER
JOIN if it is from FilteredRelation.

Simon Charette a8b3f96f6a Fixed #30408 -- Fixed crash when adding check constraints with LIKE operator on Oracle and PostgreSQL.
The LIKE operator wildcard generated for contains, startswith, endswith and

interpolation on CREATE constraint statement execution.

Ideally we'd delegate parameters interpolation in DDL statements on backends
that support it but that would require backward incompatible changes to the
Index and Constraint SQL generating methods.

Simon Charette 26c4be2ebe Refs #18676 -- Enabled fast-delete for m2m_changed senders.
There's no reason to disable fast-delete when an intermediary
many-to-many model has connected m2m_changed receivers because the
signal is only sent when related manager's clear() and remove() methods
are directly called.

This must have been overlooked in 1cd6e04cd4
given no regression tests fail when m2m_changed is not taken into
consideration to determine if fast-delete can be enabled.
