Backport of 9c19aff7c7561e3a82978a272ecdaad40dda5c00 from main.

[4.0.x] Fixed #33159 -- Reverted "Fixed #32970 -- Changed WhereNode.clone() to create a shallow copy of children."

2021-09-30T09:26:53Z

This reverts commit e441847ecae99dd1ccd0d9ce76dbcff51afa863c. 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. Backport of 903aaa35e5ceaa33bfc9b19b7f6da65ce5a91dd4 from main

Fixed #32970 -- Changed WhereNode.clone() to create a shallow copy of children.

Removed unnecessary WhereNode.is_summary.

2021-08-09T17:23:29Z

Unnecessary since its introduction in 1df89a60c5b7a28d7fda4c9ba7c07f02fd7de0fa.

Fixed #27021 -- Allowed lookup expressions in annotations, aggregations, and QuerySet.filter().

2021-07-09T09:43:06Z

Fixed #32007 -- Fixed queryset crash with Q() annotation and aggregation.

2020-09-15T09:40:59Z

Thanks Gordon Wrigley for the report. Regression in 8a6df55f2dd5131282084a4edfd48f63fbf8c69a.

Fixed #29545 -- Fixed using filter lookups againts nested subquery expressions.

2019-08-17T09:24:35Z

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.

Refs #27149 -- Moved subquery expression resolving to Query.

2019-03-22T00:36:31Z

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.

Refs #30158 -- Added alias argument to Expression.get_group_by_cols().
