Small regression in #2231.
The shallow copy done with `Config.copy_on_model_validation = True` (default behaviour)
was using excluded / included fields when it should just copy everything

* chore(ci): update python 3.10 version
* Revert "fix: enum repr is different with 3.10+"
This reverts commit b1c8d9ef1396959ff9d88bb2ed16d99dd3146151.
* refactor: extra `BaseConfig` and `Extra` in dedicated `config` module
* refactor: clean useless `#noqa: F401`
* refactor: clean useless `#noqa: F811`
* refactor: replace enum check
Error with 3.10
> DeprecationWarning: accessing one member from another is not supported
* refactor: avoid using `distutils` directly
error with python 3.10
> DeprecationWarning: The distutils package is deprecated and slated
> for removal in Python 3.12.
> Use setuptools or check PEP 632 for potential alternatives
* fix: `__annotations__` always exists
* fix: origin of `typing.Hashable` is not `None`
* ci: add run with 3.10.0b2
* docs: add 3.10
* feat: support `|` union operator properly
`|` operator has origin `types.Union` (and not `typing.Union`)
* fix: enum repr is different with 3.10+
* fix: error message changed a bit
change from basic `__init__` to `test_hashable_required.<locals>.MyDataclass.__init__()` (with `__qualname__`)
* fix: always exists and is not inherited anymore
* fix: avoid calling `asyncio.get_event_loop` directly
With python 3.10, calling it results in
> DeprecationWarning: There is no current event loop
* fix(ci): do not run 3.10 on linux for now
For now it can not be compiled.
Let's just skip the check on linux for now instead of tuning the CI pipeline
* fix(ci): ignore DeprecationWarning raised by `mypy` on windows
* docs: add change file
* add repr parameter to hide a field from repr()
* fix styling issues
… found by flake8.
* fix type annotation issues
* correctly name changes file

* Add exclude/include as field parameters
- Add "exclude" / "include" as a field parameter so that it can be
configured using model config (or fields) instead of purely at
`.dict` / `.json` export time.
- Unify merging logic of advanced include/exclude fields
- Add tests for merging logic and field/config exclude/include params
- Closes#660
* Precompute include/exclude fields for class
* Increase test coverage
* Remove (now) redundant type checks in Model._iter: New
exclusion/inclusion algorithms guarantee that no sets are passed further down.
* Add docs for advanced field level exclude/include settings
* Minimal optimization for simple exclude/include export
Running benchmarks this vs. master is at:
this: pydantic best=33.225μs/iter avg=33.940μs/iter stdev=1.120μs/iter version=1.7.3
master: pydantic best=32.901μs/iter avg=33.276μs/iter stdev=0.242μs/iter version=1.7.3
* Apply review comments on exclude/enclude field arguments
* Fix/simplify type annotations
* Allow both ``True`` and ``Ellipsis`` to be used to indicate full field
exclusion
* Reenable hypothesis plugin (removed by mistake)
* Update advanced include/include docs to use ``True`` instead of ``...``
* Move field info exclude/include updates into FieldInfo class
This way, the model field object does not need to concern itself with
dealing with field into specific fields.
(Same was done for alias in a previous commit).
* remove double back tick in markdown.

* remove DeprecationWarnings from v1 release
* coverage on unpickling Undefined private attributes
* coverage on undefined in copy, allow Undefined to be pickled unchanged
* fix coverage of model._iter()
* 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.

* fix: validate nested models with `default_factory`
PR #1504 introduced a regression by bypassing `populate_validators()`,
which would skip the validation of children in nested models
with `default_factory`
closes#1710

* Fix nested all include exclude
* Ensure original exclude value is not modified
This commit also fixes some weird cases in the recursive
`update_normalized_all` call and Ellipsis values.
* Add docstring, parametrize tests
* Avoid some side effects of default factory
- by calling it only once if possible (fix#1491)
- by not setting the default value in the schema (fix#1520)
* refactor: ensure type is set when using default_factory
