Simon Charette 3a505c70e7 Refs #27149, #29542 -- Simplified subquery parentheses wrapping logic. 2019-03-21 20:42:26 -04:00
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.

Simon Charette 96b6ad94d9 Refs #27149 -- Made Subquery store Query instead of Queryset.

Simon Charette fb3f034f1c Fixed #30158 -- Avoided unnecessary subquery group by on aggregation.
Subquery annotations can be omitted from the GROUP BY clause on aggregation
as long as they are not explicitly grouped against.

Thanks Jonny Fuller for the report.

Simon Charette 315357ad25 Fixed #30023 -- Prevented SQLite schema alterations while foreign key checks are enabled.
Prior to this change foreign key constraint references could be left pointing
at tables dropped during operations simulating unsupported table alterations
because of an unexpected failure to disable foreign key constraint checks.

SQLite3 does not allow disabling such checks while in a transaction so they
must be disabled beforehand.

Thanks ezaquarii for the report and Carlton and Tim for the review.

Simon Charette c8ffdbe514 Fixed #29182 -- Fixed schema table alteration on SQLite 3.26+.
SQLite 3.26 repoints foreign key constraints on table renames even when
foreign_keys pragma is off which breaks every operation that requires
a table rebuild to simulate unsupported ALTER TABLE statements.

The newly introduced legacy_alter_table pragma disables this behavior
and restores the previous schema editor assumptions.

Thanks Florian Apolloner, Christoph Trassl, Chris Lamb for the report and
troubleshooting assistance.

UUIDField on SQLite because the resolved expression's output field's
internal type wasn't correct. Added tests to make sure unlikely foreign
reference cycles don't cause recursion errors.

Florian Apolloner bc7dd8490b Fixed #21171 -- Avoided starting a transaction when a single (or atomic queries) are executed.
Checked the following locations:

 * Model.save(): If there are parents involved, take the safe way and use
   transactions since this should be an all or nothing operation.

   If the model has no parents:

    * Signals are executed before and after the previous existing
      transaction -- they were never been part of the transaction.

    * if `force_insert` is set then only one query is executed -> atomic
      by definition and no transaction needed.

    * same applies to `force_update`.

    * If a primary key is set and no `force_*` is set Django will try an
      UPDATE and if that returns zero rows it tries an INSERT. The first
      case is completly save (single query). In the second case a
      transaction should not produce different results since the update
      query is basically a no-op then (might miss something though).

 * QuerySet.update(): no signals issued, single query -> no transaction
   needed.

 * Model/Collector.delete(): This one is fun due to the fact that is
   does many things at once.

   Most importantly though: It does send signals as part of the
   transaction, so for maximum backwards compatibility we need to be
   conservative.

   To ensure maximum compatibility the transaction here is removed only
   if the following holds true:

     * A single instance is being deleted.
     * There are no signal handlers attached to that instance.
     * There are no deletions/updates to cascade.
     * There are no parents which also need deletion.

Michael Sanders 271542dad1 Fixed #29499 -- Fixed race condition in QuerySet.update_or_create().
A race condition happened when the object didn't already exist and
another process/thread created the object before update_or_create()
did and then attempted to update the object, also before update_or_create()
saved the object. The update by the other process/thread could be lost.

Simon Charette 8e3f22f251 Fixed #27731 -- Implemented CreateModel/AlterFooOperation reduction.

because CreateModel can perform a reduction with RemoveField.

Thanks Nick Pope for the review.

Simon Charette ed7898e1b5 Fixed #28862 -- Disabled optimization of AlterFooTogether and RemoveField.
AlterFooTogether operations cannot be swapped with RemoveField operations on
the same model as they could be removing the the same field as well.

Since AlterFooTogether operations don't track what their previous value was,
it's impossible to determine whether or not the optimization is safe so the
only way to proceed is to disable the optimization.

Thanks Ramiro Morales for the in-depth analysis of the issue.

Renamed the allow_sliced_subqueries database feature to allow_sliced_subqueries_with_in.
After 0899d583bd this database feature is
false only on MySQL which doesn't support sliced subqueries only with
IN/ALL/ANY/SOME.

Simon Charette 9f7772e098 Fixed #28884 -- Fixed crash on SQLite when renaming a field in a model referenced by a ManyToManyField.
Introspected database constraints instead of relying on _meta.related_objects
to determine whether or not a table or a column is referenced on rename
operations.

This has the side effect of ignoring both db_constraint=False and virtual
fields such as GenericRelation which aren't backend by database level
constraints and thus shouldn't prevent the rename operations from being
performed in a transaction.

Regression in 095c1aaa89.

Thanks Tim for the additional tests and edits, and Mariusz for the review.
