2ef7ff3309 Bump mypy 0.950 (#939)
* Bump mypy to 0.95x

* Remove the * for inferred types

There was an upstream change (https://github.com/python/mypy/pull/12459)
to remove * from inferred types in the reveal_type output.

As we are asserting the * to exist, all the test cases are now failing
on the 0.950 release. Removing the expected * to mirror the upstream
behaviour change should resolve the test failures.

6226381484 Recover after #909 (#925)
* Fix stubs related to `(Async)RequestFactory` and `(Async)Client`

* Revert incorrect removal.

* Allow set as `unique_together`, use shared type alias.

* Revert `Q.__init__` to use only `*args, **kwargs` to remove false-positive with `Q(**{...})`

* Add abstract methods to `HttpResponseBase` to create common interface.

* Remove monkey-patched attributes from `HttpResponseBase` subclasses.

* Add QueryDict mutability checks (+ plugin support)

* Fix lint

* Return back GenericForeignKey to `Options.get_fields`

* Minor fixup

* Make plugin code typecheck with `--warn-unreachable`, minor performance increase.

* Better types for `{unique, index}_together` and Options.

* Fix odd type of `URLResolver.urlconf_name` which isn't a str actually.

* Better types for field migration operations.

* Revert form.files to `MultiValueDict[str, UploadedFile]`

* Compatibility fix (#916)

* Do not assume that `Annotated` is always related to django-stubs (fixes #893)

* Restrict `FormView.get_form` return type to `_FormT` (class type argument). Now it is resolved to `form_class` argument if present, but also errors if it is not subclass of _FormT

* Fix CI (make test runnable on 3.8)

* Fix CI (make test runnable on 3.8 _again_)

f69e0639c7 Large update (#909)
* Make module declaration precise.

* Make settings match real file.

* Replace `include` with import.

* Make types more specific.

* Replace `WSGIRequest` with `HttpRequest` where possible.

* Replace all `OrderedDict` occurrences with plain `Dict` (it is not used in Django 3.2 and later)

* Add fake datastructures for convenience: _PropertyDescriptor and _ListOrTuple now can live here. Added _IndexableCollection (often useful as alias for 'sequence or queryset')

* Actualize other datastructures.

* Rework MultiValueDict to reflect the fact that some methods can return empty list instead of value.

* Deprecate SafeText in favor of SafeString.

* Minor improvements to utils

* Disallow using str in TimeFormat and DateFormat, drop removed fmt `B`

* Do not let classproperty expect classmethod, make return value covariant.

* Sync with real file.

* Improve types for timezone.

* Sync deprecated, new and removed features in translation utils.

* Drop removed files, sync huge deprecations.

* Fix incompatible decorators (properties, contextmanagers)

* Rework pagination.

* Sync validators with real code. Add _ValidatorCallable for any external use (field validation etc.)

* Add shared type definitions (for fields of both forms and models). Actualize model fields. Mark keyword-only args explicitly in stubs (where code uses **kwargs). Disallow bytes for verbose_name.

* Make all checks return Sequence[CheckMessage] or subclass to be covariant.

* Add bidirectional references between backend.base and other files. Replace some Any's with specific types.

* Actualize db.migrations: remove removed methods, replace "None" annotations in wrong places, improve some wrong annotations.

* Actualize db.utils to match real file.

* Replace FileResponse and TemplateResponse with HttpResponse(Base) where needed: at least HttpResponseNotModified/HttpResponseRedirect can be returned instead of it, so annotation was wrong.

* Replace Any in forms where possible. Actualize class bases and method arguments.

* Improve typing of serializers.

* Actualize views, rename variable bound to Model to _M for consistency.

* Make types of file-related code consistent. Disallow using bytes as path, because many methods expect str-only paths. Make File inherit from IO[AnyStr] instead of IO[Any]: it makes impossible to instantiate file of union type, but allows precise types for some methods.

* Minor improvements: stop using None as annotation in wrong places, replace obvious Any's with precise types, actualize methods (missing/renamed/signature changed).

* Allow less specific containers, replace Any's with specific types.

* Improve types for requests and responses.

* Use AbstractBaseUser instead of User in auth.

* Use broader type for permission_required

* Use wider container types. Add 'type: ignore' to avoid issues with mypy.stubtest.

* Disallow using backend class as argument (it is passed to import_string).

* Add required methods to PasseordValidator.

* Allow using Path instance as argument.

* Actualize methods.

* Add 'type: ignore' to avoid issues with mypy.stubtest.

* Replace Any's with specific types and BaseForm with ModelForm.

* Actualize contrib.postgres

* Remove render_to_response, add 'get_absolute_url' to corresponding protocol.

* Actualize signers.

* Use precise types for handlers. Disallow str as stream type for LimitedStream.

* Exact types for ValidationError

* Replace wrong used Union with Sequence.

* Actualize static handlers.

* More specific types for admin. Fixes #874.

* Improve types and replace 'Tags' with str (it isn't Enum, so annotation was wrong).

* Replace Any with specific types, actualize signatures.

* Add async variants of handlers and clients. Use fake class to distinguish between request types in RequestFactory and AsyncRequestFactory.

* Fix signature, minor improvements.

* Actualize signatures and class names, replace Any with more specific types.

* Fix signature.

* Add some missing methods to Collector

* Combinable rarely returns Self type: almost always it's CombinedExpression.

* No Random in source anymore.

* Drop removed SimpleCol.

* Replace _OutputField with Field: nothing in docs about strings.

* Introduce reusable types, add missing methods. Remove strange types (probably created by stubgen). Remove RawQuery from Compiler: it obviously doesn't work with RawQuery.

* Use literal constants.

* Actualize base classes.

* Callable is not accepted by get_field.

* Add precise types.

* Use property and broader containers where possible. Add missing methods.

* Actualize indexes.

* More specific types for signals.

* Fix signatures, drop missing methods.

* Actualize window functions to match source.

* Actualize text functions, add missing methods, use type aliases for consistency.

* Add missing property decorators, methods and attributes. Use type aliases. Remove absent YearComparisonLookup and any SafeText references (they aren't related to lookups at all).

* Use bound TypeVar, mark all BuiltinLookup descendants as generic explicitly. Remove strange Union from Lookup.__init__

* Apply type alias, fix base class and argument name.

* Actualize BaseExpression methods.

* Fix imports.

* Add missing class and fix incompatible bases.

* Use same types in __init__ and attribute.

* OrderBy accepts F or Expression.

* Non-expressions are converted to Values.

* Add missing attributes.

* Add missing methods, fix 'None' argument type.

* Define properties where possible, remove 'None' argument annotations, remove inadequate type in make_immutable_fields_list.

* Remove absent QueryWrapper. Replace some Any with precise types.

* Fix wrong types and actualize signatures. Deny ManagerDescriptor.__get__ on model instances.

* Use more specific types.

* Arity can be None in subclasses.

* Reformat with black

* Make DeletionMixin generic.

* Fix wrong type variable in _RequestFactory.

* Fix variable name in signature.

* Disallow returning None from Form.clean()

* Allow again returning None from Form.clean

* Drop some unused imports.

* Add tests for MultiValueDict.

* Add tests for utils.timezone.

* Fix #834.

* Add more files to import_all test

* Allow None for `context_object_name`

* Fix CI

* Fix test to work on python 3.8

799b41fe47 fix typing on HttpResponse and StreamingHttpResponse (#712)
While the documentation for `HttpResponse` and `StreamingHttpResponse`
*says* `content` and `streaming_content` should be bytestrings [1] or an
iterable of bytestrings respectively [2], this is not what the API
supports [3] [4] and there are tests which make sure the API supports
more than bytestrings [5] [6] [etc]. Before assigning `content` or
`streaming_content` the code paths will call  `self.make_bytes` to
coerce the value to bytes.

cfd69c0acc QuerySet.annotate improvements (#398)
* QuerySet.annotate returns self-type. Attribute access falls back to Any.

- QuerySets that have an annotated model do not report errors during .filter() when called with invalid fields.
- QuerySets that have an annotated model return ordinary dict rather than TypedDict for .values()
- QuerySets that have an annotated model return Any rather than typed Tuple for .values_list()

* Fix .annotate so it reuses existing annotated types. Fixes error in typechecking Django testsuite.

* Fix self-typecheck error

* Fix flake8

* Fix case of .values/.values_list before .annotate.

* Extra ignores for Django 2.2 tests (false positives due to tests assuming QuerySet.first() won't return None)

Fix mypy self-check.

* More tests + more precise typing in case annotate called before values_list.

Cleanup tests.

* Test and fix annotate in combination with values/values_list with no params.

* Remove line that does nothing :)

* Formatting fixes

* Address code review

* Fix quoting in tests after mypy changed things

* Use Final

* Use typing_extensions.Final

* Fixes after ValuesQuerySet -> _ValuesQuerySet refactor. Still not passing tests yet.

* Fix inheritance of _ValuesQuerySet and remove unneeded type ignores.

This allows the test
"annotate_values_or_values_list_before_or_after_annotate_broadens_type"
to pass.

* Make it possible to annotate user code with "annotated models", using PEP 583 Annotated type.

* Add docs

* Make QuerySet[_T] an external alias to _QuerySet[_T, _T].

This currently has the drawback that error messages display the internal type _QuerySet, with both type arguments.

See also discussion on #661 and #608.

Fixes #635: QuerySet methods on Managers (like .all()) now return QuerySets rather than Managers.

Address code review by @sobolevn.

* Support passing TypedDicts to WithAnnotations

* Add an example of an error to README regarding WithAnnotations + TypedDict.

* Fix runtime behavior of ValuesQuerySet alias (you can't extend Any, for example).

Fix some edge case with from_queryset after QuerySet changed to be an
alias to _QuerySet. Can't make a minimal test case as this only occurred
on a large internal codebase.

* Fix issue when using from_queryset in some cases when having an argument with a type annotation on the QuerySet.

The mypy docstring on anal_type says not to call defer() after it.

9251520f66 Allow Views to return the more generic HttpResponseBase instead of HttpResponse, to allow returning StreamingHttpResponse (#607)
* Add type hints for the postgres CursorDebugWrapper, expand the BaseCursorDebugWrapper.

* Fix how Optinal gets applied.

* Fix optional handling further.

* Adjust postgres debugcursorwrapper to look more like the implementation.

* Apply review feedback.

* Use the more generic HttpResponseBase when appriopriate.

* Fix failing test and add new test.

* Remove the other test again, it was the wrong location. Add new tests in the correct location.
