* fix#2293: Properly encode Decimals without any decimal places.
* doc: Added changelog entry.
* refactor: Move ConstrainedDecimal test from separate file into test_json
* docs: Remove prefix from changelog.
* test: Changed test_con_decimal_encode to @samuelcolvins recommendations
* fix(mypy): handle FilePath and DirectoryPath custom types
closes#2098
* fix(mypy): handle almost all other custom types
* remove mypy overwrite when extra logic is set
* fix unused mypy ignore
* feature: add a `frozen` parameter to config
For now, `frozen` is a strict duplication of `allow_mutation` parameter
i.e. setting `frozen=True` does everything that `allow_mutation=False` does.
NB: this does not change the behavior of `allow_mutation`.
In next commit, setting `frozen=True` will also make the BaseModel hashable
while the existing behavior of `allow_mutation` will not be updated.
* refactor: factorise immutability tests
* feature: generate a hash function when frozen is True
Now, setting `frozen=True` also generate a hash function for the model
i.e. `__hash__` is not `None`. This makes instances of the model potentially
hashable if all the attributes are hashable. (default: `False`)
* reviewer feedback: use hash of the class instead of the super
* reviewer feedback: fix spelling checks
* reviewer feedback: update changes description
* test: remwork mypy tests in order to catch only frozen related errors
Before: there were errors about other stuff than frozen behavior
After: The modification catch only errot related to the frozen behavior
* test: split test_immutablity in 2 functions
One function tests the behavior: 'the model is mutable'
The other tests the behavior:OC 'the model is immutable'
* test mutability: remove the unnecessary parametrization
* test immutability: remove assertion that do not test frozen behavior
* add support for class kwargs config
* reformat tests
* add changes file and docs
* fix linting in 'inherit_config'
* tweak docs

* Propagate`ClassVar`s to sub-models
Currently, if a `ClassVar` is defined on a model and re-defined
on a sub-model omitting the `ClassVar` annotation, Pydantic produces an
unrelated error:
NameError: Field name "..." shadows a BaseModel attribute ...
This check was introduced to prevent shadowing Pydantic's own methods
and attributes defined on the `BaseModel` class. Following this change,
class variables (that is, variables annotated with `ClassVar`)
defined on parent models will be inherited by sub-models and
will be overwritable without having to reapply the annotation.
Closes#2061.
* docs: explain how attributes are excluded and when to use `PrivateAttr`

* fix(decorator): detect when a duplicate argument is passed in
Currently, it is possible to override a positional argument with a keyword
argument using the decorator.
In native python, this raises a TypeError.
Detect this usecase, to prevent keywords overriding positional parameters.
Closes: https://github.com/samuelcolvin/pydantic/issues/2249
* add changelog entry
* fix docs example to not override positional argument

* 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

* fix(fields): handle properly default value for type `Callable`
closes#1596
* chore: move test in test_dataclasses
* chore: add comments
* test: rewrite test

* 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 :)
