* fix(decorator): align kwargs behaviour with native python
Previously, validate_arguments would strip the value if the keyword
was the same as the target kwargs argument.
Align with Python's behaviour.
* fix: also prevent overwriting variable args
Introduces tests for both, which compare against the native python implementation

* mention about 'args' in the changelog too
* simplify var_kwargs pop

* fix(fields): handle properly default value for type `Callable`
closes#1596
* chore: move test in test_dataclasses
* chore: add comments
* test: rewrite test
* chore: remove useless variable
* fix(schema): add support when callable field has default value
closes#2086
* fix: check only first sublevel for validators with `each_item`
When using a validator with `each_item`, the items are all validated
one by one. But if the items are also iterable the subitems would then
be validated because the validator would be kept as it is.
Now the validator passed to the items is changed and won't be propagated
closes#1933
* chore: add breaking change
* fix: ensure to always return one of the values in `Literal` field type
closes#2166
* perf: improve `literal_validator` speed
Thanks to @yobiscus
* fix: when more options in Literal
switch from `set` to `dict` to still have a O(1) complexity
Thanks @layday :)
* feat: add validator for NoneType
closes#2095
* feat: support NoneType directly as type
* chore: add change file
* chore: fix typo
* fix: handle Literal[None] for python3.6/3.7 without typing_extensions
* chore: move NotNoneError and export it
* chore: use constant NONE_TYPES to simplify a bit
* chore: use check on Literal instead of typing_extensions
These tests would not run on python 3.8+ without typing_extensions
even though Literal is defined
* test: use fresh Literal[None] in test case
* feat: handle `None` type in schema
* docs: add NoneType documentation
* refactor: switch NONE_TYPES from tuple to set
* Fix#947, fix#1483, fix#1247 allow inner type vars to be present in parent generic classes
- Rename generics._is_type to _is_generic in response to comment:
https://github.com/samuelcolvin/pydantic/pull/1989#discussion_r503400391
- Add more explicit type assertion in generics test
- Add generics tests and unify naming
- Move deep generic tests all into same place in code
- Unify naming convention in deep generic tests using naming of existing tests
- Add tests for multiple inheritance and multiple type vars
- Add generic tests for type hint resolution cases
- Fix edge cases for handling parameters in generic models
- Resolve parameters correctly
- Add tests for special cases like callables
- Add returning generic type directly if parameters and arguments are
identical.
* Apply review comments
- Add docstrings
- Small refactor `generics.__concrete_name__`
- Small refactor of `generics.resolve_type_hints`
- Change `is_identity_typevars_map` to more generic and clearer
`all_identical` and move into utils.
- rename "resolve_type_hint" to "replace_types" so as to not get
confused with "resolve_annotations" from `pydantic.typing`
* Fix generics test coverage
* Update pydantic/generics.py, remove unneeded annotation
mypy understands list comprehensions as they are now

* Code format
* More code format
* Add changes file

Following #2000 and #2046 we can't `pop` the current value when assigning
a new one (which was probably the most efficient) as we want to keep the
order in the `__dict__`.
So let's do a shallow copy of the `__dict__` without the current value
fix#2073
* don't pop the value off __dict__
* adding change description
* still pop the field, but catch any exc, set the field to og value, and reraise exc
* adding tests
* fixing test
* improve tests/test_validators.py tests

* refactor: remove `_dataclass_with_validation` function
* docs: add docstring for `make_dataclass_validator`
* refactor: rename DataclassType into Dataclass
The name `DataclassType` was missleading as it's not a `Type` per say.
* refactor: change global `dataclass` import to local
pydantic import time was improved in
https://github.com/samuelcolvin/pydantic/pull/1132
by keeping `dataclass` import local. So let's keep it that way!
