2022-05-04Refs #33646 -- Reduced sync_to_async hops on async QuerySet iteration.Simon Charette
Until we add support for truly asynchronous database backends it's actually detrimental to have complete set retrieval require multiple hops between sync and async emulated contexts via asgiref. By defaulting to sending the whole sync _fetch_all() to the current context thread pool we reduce unncessary work when dealing with large result sets since the queryset cannot be iterated anyway before all results are retrieved and cached.

2022-03-31Fixed #33397 -- Corrected resolving output_field for ↵Luke Plant
DateField/DateTimeField/TimeField/DurationFields. This includes refactoring of CombinedExpression._resolve_output_field() so it no longer uses the behavior inherited from Expression of guessing same output type if argument types match, and instead we explicitly define the output type of all supported operations. This also makes nonsensical operations involving dates (e.g. date + date) raise a FieldError, and adds support for automatically inferring output_field for cases such as: * date - date * date + duration * date - duration * time + duration * time - time
2022-03-31Refs #33397 -- Added register_combinable_fields().Luke Plant

get_loaded_field_names() is no longer called in multiple places (see 0c7633178fa9410f102e4708cef979b873bccb76) and it's redundant with SQLCompiler.deferred_to_columns().
2022-03-31Updated select_related_descend() comment.Mariusz Felisiak
Outdated since 0c7633178fa9410f102e4708cef979b873bccb76.
