Simon Charette 379bf1a2d4 Fixed #8467 -- Prevented crash when adding existent m2m relation with an invalid type.
This was an issue anymore on backends that allows conflicts to be
ignored (Refs #19544) as long the provided values were coercible to the
expected type. However on the remaining backends that don't support
this feature, namely Oracle, this could still result in an
IntegrityError.

By attempting to coerce the provided values to the expected types in
Python beforehand we allow the existing value set intersection in
ManyRelatedManager._get_missing_target_ids to prevent the problematic
insertion attempts.

Thanks Baptiste Mispelon for triaging this old ticket against the
current state of the master branch.

Nick Pope 7286eaf681 Refs #13312 -- Simplified handling of nulls ordering on MySQL.

the same workaround used for NULLS FIRST and NULLS LAST that is

Simon Charette 7acef095d7 Fixed #23576 -- Implemented multi-alias fast-path deletion in MySQL backend.
This required moving the entirety of DELETE SQL generation to the
compiler where it should have been in the first place and implementing
a specialized compiler on MySQL/MariaDB.

The MySQL compiler relies on the "DELETE table FROM table JOIN" syntax
for queries spanning over multiple tables.

OuterRef right hand sides have to be nested, just like F rhs have to,

Simon Charette 600628f8f0 Refs #28442 -- Adjusted related lookups handling of expression rhs.
Expressions should never be prepared as other Lookup.get_prep_lookup
implementations hint at by returning early on the presence of the
resolve_expression attribute.

The previous solution was only handling lookups against related fields
pointing at AutoFields and would break for foreign keys to other fields.

It was also causing bidirectional coupling between model fields and
expressions which the method level import of OuterRef was a symptom of.

future auto field types such as a theoretical UUIDAutoField.

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.

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.

There's no reason to disable fast-delete when an intermediary

signal is only sent when related manager's clear() and remove() methods
are directly called.

This must have been overlooked in 1cd6e04cd4

consideration to determine if fast-delete can be enabled.

Simon Charette 3543129822 Refs #27149 -- Moved subquery expression resolving to Query.
This makes Subquery a thin wrapper over Query and makes sure it respects
the Expression source expression API by accepting the same number of
expressions as it returns. Refs #30188.

It also makes OuterRef usable in Query without Subquery wrapping. This
should allow Query's internals to more easily perform subquery push downs
during split_exclude(). Refs #21703.
