Mariusz Felisiak 93a42d43a6 [4.0.x] Fixed #33159 -- Reverted "Fixed #32970 -- Changed WhereNode.clone() to create a shallow copy of children." 
This reverts commit e441847eca.

A shallow copy is not enough because querysets can be reused and
evaluated in nested nodes, which shouldn't mutate JOIN aliases.

Thanks Michal Čihař for the report.

Keryn Knight 5353e7c250 Refs #27624 -- Optimized Query.clone() for non-combined queries. 
This avoids constructing a generator expression and a new tuple if the
Query has no combined queries.

Adam Johnson fc91ea1e50 Refs #27624 -- Changed Query.explain_info to namedtuple. 2021-09-17 07:15:12 +02:00
Adam Johnson 2931d847c2 Optimized Query.clone() a bit. 
This removes unnecessary "if ... is None" branches, which are already
shallow-copied in the __dict__.copy() call.

Matjaz Gregoric 518ce7a51f Fixed #33017 -- Fixed storage engine introspection on MySQL. 
This also improves performance on MySQL instances with a large number
of databases, since querying the information_schema table can be very
slow
 2021-08-20 11:05:21 +02:00
Matjaz Gregoric e9aa20e4e1 Optimized DatabaseSchemaEditor._field_should_be_indexed() on MySQL. 2021-08-20 10:30:02 +02:00
Keryn Knight bf5abf1bdc Fixed #33025 -- Avoided accessing the database connections in Query.build_lookup() when not necessary. 
Of the built-in backends, only Oracle treats empty strings and nulls as
equal, so avoid testing the default connection backend for
interprets_empty_strings_as_nulls if it can be established from the
lookup that it wouldn't affect the lookup instance returned. This
improves performance a small amount for most lookups being built,
because accessing the connections requires touching the thread critical
`Local` which is an expensive operation.

Chris Jerdonek 7800596924 Fixed #33014 -- Made ProjectState raise exception when real_apps argument is not a set. 2021-08-19 10:18:51 +02:00

Removed unnecessary WhereNode.is_summary. 
Unnecessary since its introduction in 1df89a60c5.
 2021-08-09 19:23:29 +02:00
Keryn Knight 921e4ccb77
Fixed #33003 -- Removed **kwargs from QuerySet._chain(). 
The functionality of updating the __dict__ was only present to allow
for pickling a Prefetch object, which is a comparably rare operation.
Forcing the __getstate__() implementation to handle it allows the
chaining operation to be slightly faster, which is much more common.

Nick Touran 5d4f21b16f Fixed #32983 -- Added system check for redundant related_name on symmetrical M2M fields. 
Since ManyToManyFields defined with `symmetrical=True` do not add a
related field to the target model, including a `related_name` argument
will never do what the coder likely expects. This makes including
a related_name with a symmetrical model raise a system check warning.

Keryn Knight 9662193aea Refs #32946 -- Changed internal usage of dynamic Q() objects construction to use non-kwargs initialization. 
This prefers non-kwargs construction of dynamically generated Q()
objects to create a single Q() object instead of many and then
combining them, where possible.

Optimized BaseDatabaseSchemaEditor._effective_default() a bit, 
This eliminates an unneeded call to datetime.now() when
field.get_internal_type() equals "DateTimeField".

David Smith 1cba320786
Refs #32956 -- Changed "afterwards" to "afterward" in docs and comments. 
This also removes unnecessary comments with the previous spelling.

AP Stylebook has a short entry to advise the preferred spelling for
"en-us". "Afterwards" is preferred in British English.
