You are a principal Python software engineer resolving a repository issue in `/workspace`.
Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run.

## Critical Environment & Grader Rules
1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`.
2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files.
3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`.
4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks:
   `pytest path/to/test_file.py -k pattern -q --tb=short --no-header`
   If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off.
5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission.

## Execution Protocol

### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls)
- The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories.
- Run a single compound `run_command` with `grep -rn --include="*.py"` to locate:
  (a) the exact symbols, error strings, or functions from the problem description,
  (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and
  (c) the closest existing unit test files under `tests/`.

### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls)
- Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests.
- Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types.

### Phase 3 — Reproduce Bug in One Call (1 tool call)
- Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts.

### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls)
- Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`.
- Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests.
- **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`.

### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls)
- Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`.
- Run `git status --short && git diff` via `run_command`. Confirm:
  - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately),
  - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched),
  - Minimal, clean diff with valid imports and indentation.
- Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

When trying to use the `validate_arguments` decorator, I face the issue of getting validation errors for an extra attribute for a TypedDict as below:

```py
from typing_extensions import TypedDict

from pydantic import validate_arguments, Extra


class TypedTest(TypedDict):
    y: str


@validate_arguments(config={'extra': Extra.allow})
def test(other: TypedTest):
    pass


test(other={'y': 'b', 'z': 'a'})

```

Output:
```
pydantic.error_wrappers.ValidationError: 1 validation error for Test
other -> z
  extra fields not permitted (type=value_error.extra)
```

Expected: No errors

Anything I have missed that would let this validation pass for extra attributes in the TypedDict?

Thanks very much!

## Task Budget (Session terminates when any budget is exhausted)
- Time allowance: 7.5 minutes
- Tool calls allowance: 30 calls
- Max loop iterations: 40 turns

## Execution Environment Rules
- Single command timeout: 90 seconds (commands exceeding this fail without ending the session)
- Command output limit: 5000 characters
- File view limit: 150 lines per read_file call
- File character limit: 10000 characters per read_file call
- Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages.

## Instructions:
0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages.
1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules.
2. Inspect existing codebase conventions and test files before making edits.
3. Verify your implementation using targeted tests or inline assertions before submitting.
4. Call submit_patch only after your implementation is complete and verified.
5. As your final action, you must return a text-only response reporting your completion to terminate the session.

The user is reporting a bug where `Extra.allow` config in `@validate_arguments` is not respected when the function argument is a `TypedDict`.

Example provided:
```python
from typing_extensions import TypedDict
from pydantic import validate_arguments, Extra

class TypedTest(TypedDict):
    y: str

@validate_arguments(config={'extra': Extra.allow})
def test(other: TypedTest):
    pass

test(other={'y': 'b', 'z': 'a'})
```
This fails with `pydantic.error_wrappers.ValidationError: 1 validation error for Test other -> z extra fields not permitted (type=value_error.extra)`.

I need to investigate how `validate_arguments` handles `TypedDict` and how the `extra` config is applied.

First, I'll reproduce this bug with a script.

I'll start by searching for `validate_arguments` and `TypedDict` in the codebase.

It seems `pydantic/decorator.py` contains `validate_arguments`.
And `pydantic/validators.py` has some logic for `TypedDict` and `create_model_from_typeddict`.

Let's look at `pydantic/decorator.py` first to see how it uses the `config`.

It seems `pydantic/decorator.py` contains `validate_arguments`. And `pydantic/validators.py` has some logic for `TypedDict` and `create_model_from_typeddict`.

In `create_model` method of `ValidatedFunction`:
```python
        class DecoratorBaseModel(BaseModel):
            # ... validators ...
            class Config(CustomConfig):
                extra = Extra.forbid
```
It seems `extra = Extra.forbid` is hardcoded in `DecoratorBaseModel.Config`.
Wait, it's `class Config(CustomConfig): extra = Extra.forbid`.
If `CustomConfig` (which comes from the `config` argument to `validate_arguments`) has `extra = Extra.allow`, it will be overridden by `extra = Extra.forbid` in the inner `Config` class.

Let's check the provided example:
```python
@validate_arguments(config={'extra': Extra.allow})
def test(other: TypedTest):
    pass
```
Here `config={'extra': Extra.allow}`.
`CustomConfig` will be a class with `extra = Extra.allow`.
Then `DecoratorBaseModel.Config(CustomConfig)` will have `extra = Extra.forbid`.

So the `extra` config on the `DecoratorBaseModel` is always `Extra.forbid`.
However, the error is reported for `other -> z`.
`other` is an argument of the function `test`.
The `fields` passed to `create_model` include `other`.
The type of `other` is `TypedTest` (a `TypedDict`).

The `DecoratorBaseModel` is created as:
`self.model = create_model(to_camel(self.raw_function.__name__), __base__=DecoratorBaseModel, **fields)`

When `test(other={'y': 'b', 'z': 'a'})` is called:
1. `build_values` is called, resulting in `values = {'other': {'y': 'b', 'z': 'a'}, ...}`.
2. `self.model(**values)` is called.
3. The `DecoratorBaseModel` (or rather the model created by `create_model`) validates its fields.
4. The `other` field is validated against `TypedTest`.

If `TypedTest` is a `TypedDict`, Pydantic likely creates a model for it.
Let's look at how Pydantic handles `TypedDict`.
Earlier `grep` showed `pydantic/validators.py` has `typeddict_validator` and `create_model_from_typeddict`.

```python
pydantic/validators.py:592:    def typeddict_validator(values: 'TypedDict') -> Dict[str, Any]:  # type: ignore[valid-type]
pydantic/validators.py:593:        return TypedDictModel.parse_obj(values).dict(exclude_unset=True)
```
And
```python
pydantic/validators.py:585:    TypedDictModel = create_model_from_typeddict(
pydantic/validators.py:590:    typeddict_cls.__pydantic_model__ = TypedDictModel  # type: ignore[attr-defined]
```

The `TypedDictModel` is created using `create_model_from_typeddict`. Let's find where that is defined.

`create_model_from_typeddict` uses `create_model(typeddict_cls.__name__, **kwargs, **field_definitions)`.
The `**kwargs` here would be where the `Config` (and thus `extra`) would come from.

Now let's see where `create_model_from_typeddict` is called.
Previously I saw it in `pydantic/validators.py`:

```python

pydantic/validators.py:590:    typeddict_cls.__pydantic_model__ = TypedDictModel  # type: ignore[attr-defined]
```

Let's read `pydantic/validators.py` around line 585.

So the function is `find_validators(type_, config)`.

Wait, I was looking for how `validate_arguments` uses this.
`validate_arguments` creates a `DecoratorBaseModel` (from `pydantic/decorator.py`).
`DecoratorBaseModel` is a `BaseModel`.
`self.model = create_model(to_camel(self.raw_function.__name__), __base__=DecoratorBaseModel, **fields)`

When `self.model(**values)` is called, Pydantic's `BaseModel` validation kicks in.
In Pydantic v1, `BaseModel` uses its `__fields__` and their validators.

If a field has type `TypedTest`, Pydantic likely creates a validator for it.
Let's see how `create_model` handles types that are `TypedDict`.

Actually, `create_model` just creates a `BaseModel` with the given fields and types.
Then when `parse_obj` (or `__init__`) is called, it iterates over fields and applies validators.

If the type is a `TypedDict`, the validator is likely created by `find_validators` (or something similar) and applied.

In `find_validators`:
```python
    if is_typeddict(type_):
        yield make_typeddict_validator(type_, config)
        return
```
And `make_typeddict_validator`:
```python
def make_typeddict_validator(
    typeddict_cls: Type['TypedDict'], config: Type['BaseConfig']  # type: ignore[valid-type]
) -> Callable[[Any], Dict[str, Any]]:
    from .annotated_types import create_model_from_typeddict

    TypedDictModel = create_model_from_typeddict(
        typeddict_cls,
        __config__=config,
        __module__=typeddict_cls.__module__,
    )
    typeddict_cls.__pydantic_model__ = TypedDictModel  # type: ignore[attr-defined]

    def typeddict_validator(values: 'TypedDict') -> Dict[str, Any]:  # type: ignore[valid-type]
        return TypedDictModel.parse_obj(values).dict(exclude_unset=True)

    return typeddict_validator
```

The `config` passed to `make_typeddict_validator` is the config of the model being validated (the `DecoratorBaseModel` instance).

Now let's look at `DecoratorBaseModel` in `pydantic/decorator.py`:
```python
        class DecoratorBaseModel(BaseModel):
            # ...
            class Config(CustomConfig):
                extra = Extra.forbid
```
Here `CustomConfig` is the config passed to `@validate_arguments(config=...)`.
In the example, `config={'extra': Extra.allow}`.
So `CustomConfig` has `extra = Extra.allow`.
But `DecoratorBaseModel.Config` has `extra = Extra.forbid`.

Wait, if `CustomConfig` has `extra = Extra.allow`, and `Config(CustomConfig)` has `extra = Extra.forbid`, then the final `extra` is `Extra.forbid`.
This means any extra arguments to the function itself will be forbidden.
But the error is `other -> z`, which means inside the `other` argument (which is a `TypedDict`), an extra field `z` was found.

The validator for `other` is created via `make_typeddict_validator(TypedTest, config)`.
The `config` here is `DecoratorBaseModel.Config`.
So `TypedDictModel` is created with `__config__=DecoratorBaseModel.Config`.
Since `DecoratorBaseModel.Config.extra` is `Extra.forbid`, the `TypedDictModel` also has `extra = Extra.forbid`.

So if the user specifies `config={'extra': Extra.allow}` in `@validate_arguments`, it's being overridden by `extra = Extra.forbid` in `DecoratorBaseModel.Config`.

Let's verify this.
If I change `DecoratorBaseModel.Config` to not hardcode `extra = Extra.forbid`, maybe it will work.

Wait, if I just remove `extra = Extra.forbid` from `DecoratorBaseModel.Config`, then it will inherit `extra` from `CustomConfig`.
If `CustomConfig` doesn't have `extra`, it will inherit from `BaseModel.Config` (which defaults to `Extra.ignore` in Pydantic v1, I think).

But `validate_arguments` seems to want to forbid extra arguments to the function by default.
Wait, if I have:
```python
@validate_arguments
def test(a: int):
    pass

test(a=1, b=2)
```
This should probably fail with "unexpected keyword argument: 'b'".
And indeed, the `DecoratorBaseModel` has validators for `v__args` and `v__kwargs` to handle this.

Wait, `DecoratorBaseModel` has:
```python
            @validator(self.v_kwargs_name, check_fields=False, allow_reuse=True)
            def check_kwargs(cls, v: Optional[Dict[str, Any]]) -> Optional[Dict[str, Any]]:
                if takes_kwargs or v is None:
                    return v

                plural = '' if len(v) == 1 else 's'
                keys = ', '.join(map(repr, v.keys()))
                raise TypeError(f'unexpected keyword argument{plural}: {keys}')
```
And `v_kwargs_name` is (usually) `'kwargs'`.
If the function doesn't take `**kwargs`, then any extra kwargs are put into `self.v_kwargs_name` by `build_values` and then validated by `check_kwargs`, which raises `TypeError`.

So the `extra = Extra.forbid` in `DecoratorBaseModel.Config` might be for something else?
Or maybe it was intended to also forbid extra fields in models passed as arguments?
But `TypedDict` is not a `BaseModel`. However, `make_typeddict_validator` uses `config` to create a `TypedDictModel` (which is a `BaseModel`).

If `DecoratorBaseModel.Config.extra` is `Extra.forbid`, then any model (including the one created for `TypedDict`) will have `extra = Extra.forbid`.

If I change:
```python
            class Config(CustomConfig):
                extra = Extra.forbid
```
to something that respects `CustomConfig.extra` if it's set, but defaults to `Extra.forbid` if not.

But wait, `CustomConfig` is a class.
If the user provides `config={'extra': Extra.allow}`, `CustomConfig` will have `extra = Extra.allow`.
In that case, `class Config(CustomConfig): extra = Extra.forbid` explicitly overrides it.

If I change it to:
```python
            class Config(CustomConfig):
                pass
```
Then it will use `CustomConfig.extra`.
What is the default if `config` is `None`?
If `config` is `None`, `CustomConfig` is the empty class `class CustomConfig: pass`.
Then `class Config(CustomConfig): pass` will have the default `extra` from `BaseModel.Config`.
In Pydantic v1, the default `extra` is `Extra.ignore`.

If `validate_arguments` wants to forbid extra fields by default, it should set `extra = Extra.forbid`.

Wait, if I use `Extra.ignore` (default), does it still forbid extra arguments to the function?
Yes, because of the `check_kwargs` validator in `DecoratorBaseModel`.
`check_kwargs` is not related to `Config.extra`. It's a validator on the `v_kwargs_name` field.

Wait, `build_values` put extra kwargs into `self.v_kwargs_name`.
```python
        for k, v in kwargs.items():
            if k in non_var_fields:
                # ...
                values[k] = v
            else:
                var_kwargs[k] = v

        if var_kwargs:
            values[self.v_kwargs_name] = var_kwargs
```
And `check_kwargs` validates `self.v_kwargs_name`.
So `extra = Extra.forbid` in `Config` is not used for the function's arguments themselves.

Then why is it there?
Maybe it's to prevent adding attributes to the `DecoratorBaseModel` instance itself? But we only use it for validation of the arguments.

Wait, the error in the reproduction is:
`pydantic.error_wrappers.ValidationError: 1 validation error for Test other -> z extra fields not permitted (type=value_error.extra)`
This is a `ValidationError`, not a `TypeError`.
`TypeError` is what `check_kwargs` raises.
`ValidationError` is what `TypedDictModel.parse_obj()` raises.
`TypedDictModel` is a `BaseModel` created with `__config__=config`, where `config` is `DecoratorBaseModel.Config`.

So if `DecoratorBaseModel.Config.extra = Extra.forbid`, then `TypedDictModel` will forbid extra fields.
And that's exactly what's happening.

If the user wants `Extra.allow`, they pass it via `config`.
But `DecoratorBaseModel.Config` overrides it.

If I change:
```python
            class Config(CustomConfig):
                extra = Extra.forbid
```
to:
```python
            class Config(CustomConfig):
                extra: Any = getattr(CustomConfig, 'extra', Extra.forbid)
```
Wait, `Config` is a class. I can't just do that.

I can do:
```python
        # In create_model method of ValidatedFunction
        # ...
        if not TYPE_CHECKING:  # pragma: no branch
            if isinstance(config, dict):
                CustomConfig = type('Config', (), config)  # noqa: F811
            elif config is not None:
                CustomConfig = config  # noqa: F811
```
`CustomConfig` is already a class.

If I change:
```python
            class Config(CustomConfig):
                extra = Extra.forbid
```
to
```python
            class Config(CustomConfig):
                pass
```
Then it will use `CustomConfig.extra` if it exists, otherwise it'll be `BaseModel.Config.extra` (which is `Extra.ignore`).

Is that okay?
If `config` was `None`, `CustomConfig` is the empty class. `Config(CustomConfig)` will have `extra = Extra.ignore`.
Does the user expect `extra = Extra.forbid` by default?
The issue says "Expected: No errors" when `config={'extra': Extra.allow}` is passed.

If I want to keep the default as `Extra.forbid` but allow overriding:

```python
        # ...
        if not TYPE_CHECKING:  # pragma: no branch
            if isinstance(config, dict):
                # Ensure default extra is forbid if not provided in dict
                if 'extra' not in config:
                    config['extra'] = Extra.forbid
                CustomConfig = type('Config', (), config)  # noqa: F811
            elif config is not None:
                # If config is a class, we can't easily check and set a default attribute
                # unless we subclass it or modify it.
                CustomConfig = config  # noqa: F811
            else:
                # Default config
                class CustomConfig:
                    extra = Extra.forbid
```
Wait, if `config` is `None`, the original code does:
```python
        class CustomConfig:
            pass
```
And then `class Config(CustomConfig): extra = Extra.forbid`.
So if `config` is `None`, `extra` is `Extra.forbid`.

If I change it to:
```python
        class DecoratorBaseModel(BaseModel):
            # ...
            class Config(CustomConfig):
                extra: Any = getattr(CustomConfig, 'extra', Extra.forbid)
```
Actually, in Pydantic v1 `Config` classes are handled in a special way.

Wait, what if I just do:
```python
        # In create_model
        # ...
        if not TYPE_CHECKING:  # pragma: no branch
            if isinstance(config, dict):
                CustomConfig = type('Config', (), config)  # noqa: F811
            elif config is not None:
                CustomConfig = config  # noqa: F811
            else:
                class CustomConfig:
                    pass
        
        # ...
        
        class DecoratorBaseModel(BaseModel):
            # ...
            class Config(CustomConfig):
                # Use CustomConfig.extra if available, otherwise default to Extra.forbid
                extra: Any = getattr(CustomConfig, 'extra', Extra.forbid)
```
Wait, `extra: Any = ...` might not work as expected for a Pydantic `Config` class if it's not a simple assignment.

Let's see how `BaseModel.Config` is implemented or how it should be.
Actually, the simplest way is to check if `CustomConfig` already has `extra`.

If I do:
```python
        # ...
        if not TYPE_CHECKING:  # pragma: no branch
            if isinstance(config, dict):
                CustomConfig = type('Config', (), config)  # noqa: F811
            elif config is not None:
                CustomConfig = config  # noqa: F811
            else:
                class CustomConfig:
                    pass
        
        # ...
        
        class DecoratorBaseModel(BaseModel):
            # ...
            class Config(CustomConfig):
                # Remove this:
                # extra = Extra.forbid
                pass
```
But then I need to ensure that `extra` defaults to `Extra.forbid` if the user didn't provide it.

If the user provides `config={'extra': Extra.allow}`, `CustomConfig` has `extra = Extra.allow`. `Config(CustomConfig)` will have `extra = Extra.allow`. This is good.

If the user provides `config=None`, `CustomConfig` is empty. `Config(CustomConfig)` will have `extra` from `BaseModel.Config` (which is `Extra.ignore`).
If the original code had `extra = Extra.forbid` regardless of `CustomConfig`, then it's forcing `Extra.forbid`.

If I want to preserve the default `Extra.forbid`:

```python
        if not TYPE_CHECKING:  # pragma: no branch
            if isinstance(config, dict):
                if 'extra' not in config:
                    config['extra'] = Extra.forbid
                CustomConfig = type('Config', (), config)  # noqa: F811
            elif config is not None:
                # We can't easily modify config if it's a class.
                CustomConfig = config  # noqa: F811
            else:
                class CustomConfig:
                    extra = Extra.forbid
```
And then:
```python
            class Config(CustomConfig):
                pass
```
Wait, if `config` is a class and doesn't have `extra`, then `CustomConfig` doesn't have `extra`.
And `Config(CustomConfig)` won't have `extra`, so it'll use the default from `BaseModel.Config` (`Extra.ignore`).

So I should probably do:
```python
            class Config(CustomConfig):
                extra: Any = getattr(CustomConfig, 'extra', Extra.forbid)
```
Does this work for Pydantic v1 `Config` classes?
Pydantic v1 reads the `Config` class attributes.

Let's try this in a reproduction script.

So the function is `find_validators(type_, config)`. Wait, I was looking for how `validate_arguments` uses this. `validate_arguments` creates a `DecoratorBaseModel` (from `pydantic/decorator.py`). `DecoratorBaseModel` is a `BaseModel`. `self.model = create_model(to_camel(self.raw_function.__name__), __base__=DecoratorBaseModel, **fields)` When `self.model(**values)` is called, Pydantic's `BaseModel` validation kicks in. In Pydantic v1, `BaseModel` uses its `__fields__` and their validators. If a field has type `TypedTest`, Pydantic likely creates a validator for it. Let's see how `create_model` handles types that are `TypedDict`. Actually, `create_model` just creates a `BaseModel` with the given fields and types. Then when `parse_obj` (or `__init__`) is called, it iterates over fields and applies validators. If the type is a `TypedDict`, the validator is likely created by `find_validators` (or something similar) and applied. In `find_validators`: ```python if is_typeddict(type_): yield make_typeddict_validator(type_, config) return ``` And `make_typeddict_validator`: ```python def make_typeddict_validator( typeddict_cls: Type['TypedDict'], config: Type['BaseConfig'] # type: ignore[valid-type] ) -> Callable[[Any], Dict[str, Any]]: from .annotated_types import create_model_from_typeddict TypedDictModel = create_model_from_typeddict( typeddict_cls, __config__=config, __module__=typeddict_cls.__module__, ) typeddict_cls.__pydantic_model__ = TypedDictModel # type: ignore[attr-defined] def typeddict_validator(values: 'TypedDict') -> Dict[str, Any]: # type: ignore[valid-type] return TypedDictModel.parse_obj(values).dict(exclude_unset=True) return typeddict_validator ``` The `config` passed to `make_typeddict_validator` is the config of the model being validated (the `DecoratorBaseModel` instance). Now let's look at `DecoratorBaseModel` in `pydantic/decorator.py`: ```python class DecoratorBaseModel(BaseModel): # ... class Config(CustomConfig): extra = Extra.forbid ``` Here `CustomConfig` is the config passed to `@validate_arguments(config=...)`. In the example, `config={'extra': Extra.allow}`. So `CustomConfig` has `extra = Extra.allow`. But `DecoratorBaseModel.Config` has `extra = Extra.forbid`. Wait, if `CustomConfig` has `extra = Extra.allow`, and `Config(CustomConfig)` has `extra = Extra.forbid`, then the final `extra` is `Extra.forbid`. This means any extra arguments to the function itself will be forbidden. But the error is `other -> z`, which means inside the `other` argument (which is a `TypedDict`), an extra field `z` was found. The validator for `other` is created via `make_typeddict_validator(TypedTest, config)`. The `config` here is `DecoratorBaseModel.Config`. So `TypedDictModel` is created with `__config__=DecoratorBaseModel.Config`. Since `DecoratorBaseModel.Config.extra` is `Extra.forbid`, the `TypedDictModel` also has `extra = Extra.forbid`. So if the user specifies `config={'extra': Extra.allow}` in `@validate_arguments`, it's being overridden by `extra = Extra.forbid` in `DecoratorBaseModel.Config`. Let's verify this. If I change `DecoratorBaseModel.Config` to not hardcode `extra = Extra.forbid`, maybe it will work. Wait, if I just remove `extra = Extra.forbid` from `DecoratorBaseModel.Config`, then it will inherit `extra` from `CustomConfig`. If `CustomConfig` doesn't have `extra`, it will inherit from `BaseModel.Config` (which defaults to `Extra.ignore` in Pydantic v1, I think). But `validate_arguments` seems to want to forbid extra arguments to the function by default. Wait, if I have: ```python @validate_arguments def test(a: int): pass test(a=1, b=2) ``` This should probably fail with "unexpected keyword argument: 'b'". And indeed, the `DecoratorBaseModel` has validators for `v__args` and `v__kwargs` to handle this. Wait, `DecoratorBaseModel` has: ```python @validator(self.v_kwargs_name, check_fields=False, allow_reuse=True) def check_kwargs(cls, v: Optional[Dict[str, Any]]) -> Optional[Dict[str, Any]]: if takes_kwargs or v is None: return v plural = '' if len(v) == 1 else 's' keys = ', '.join(map(repr, v.keys())) raise TypeError(f'unexpected keyword argument{plural}: {keys}') ``` And `v_kwargs_name` is (usually) `'kwargs'`. If the function doesn't take `**kwargs`, then any extra kwargs are put into `self.v_kwargs_name` by `build_values` and then validated by `check_kwargs`, which raises `TypeError`. So the `extra = Extra.forbid` in `DecoratorBaseModel.Config` might be for something else? Or maybe it was intended to also forbid extra fields in models passed as arguments? But `TypedDict` is not a `BaseModel`. However, `make_typeddict_validator` uses `config` to create a `TypedDictModel` (which is a `BaseModel`). If `DecoratorBaseModel.Config.extra` is `Extra.forbid`, then any model (including the one created for `TypedDict`) will have `extra = Extra.forbid`. If I change: ```python class Config(CustomConfig): extra = Extra.forbid ``` to something that respects `CustomConfig.extra` if it's set, but defaults to `Extra.forbid` if not. But wait, `CustomConfig` is a class. If the user provides `config={'extra': Extra.allow}`, `CustomConfig` will have `extra = Extra.allow`. In that case, `class Config(CustomConfig): extra = Extra.forbid` explicitly overrides it. If I change it to: ```python class Config(CustomConfig): pass ``` Then it will use `CustomConfig.extra`. What is the default if `config` is `None`? If `config` is `None`, `CustomConfig` is the empty class `class CustomConfig: pass`. Then `class Config(CustomConfig): pass` will have the default `extra` from `BaseModel.Config`. In Pydantic v1, the default `extra` is `Extra.ignore`. If `validate_arguments` wants to forbid extra fields by default, it should set `extra = Extra.forbid`. Wait, if I use `Extra.ignore` (default), does it still forbid extra arguments to the function? Yes, because of the `check_kwargs` validator in `DecoratorBaseModel`. `check_kwargs` is not related to `Config.extra`. It's a validator on the `v_kwargs_name` field. Wait, `build_values` put extra kwargs into `self.v_kwargs_name`. ```python for k, v in kwargs.items(): if k in non_var_fields: # ... values[k] = v else: var_kwargs[k] = v if var_kwargs: values[self.v_kwargs_name] = var_kwargs ``` And `check_kwargs` validates `self.v_kwargs_name`. So `extra = Extra.forbid` in `Config` is not used for the function's arguments themselves. Then why is it there? Maybe it's to prevent adding attributes to the `DecoratorBaseModel` instance itself? But we only use it for validation of the arguments. Wait, the error in the reproduction is: `pydantic.error_wrappers.ValidationError: 1 validation error for Test other -> z extra fields not permitted (type=value_error.extra)` This is a `ValidationError`, not a `TypeError`. `TypeError` is what `check_kwargs` raises. `ValidationError` is what `TypedDictModel.parse_obj()` raises. `TypedDictModel` is a `BaseModel` created with `__config__=config`, where `config` is `DecoratorBaseModel.Config`. So if `DecoratorBaseModel.Config.extra = Extra.forbid`, then `TypedDictModel` will forbid extra fields. And that's exactly what's happening. If the user wants `Extra.allow`, they pass it via `config`. But `DecoratorBaseModel.Config` overrides it. If I change: ```python class Config(CustomConfig): extra = Extra.forbid ``` to: ```python class Config(CustomConfig): extra: Any = getattr(CustomConfig, 'extra', Extra.forbid) ``` Wait, `Config` is a class. I can't just do that. I can do: ```python # In create_model method of ValidatedFunction # ... if not TYPE_CHECKING: # pragma: no branch if isinstance(config, dict): CustomConfig = type('Config', (), config) # noqa: F811 elif config is not None: CustomConfig = config # noqa: F811 ``` `CustomConfig` is already a class. If I change: ```python class Config(CustomConfig): extra = Extra.forbid ``` to ```python class Config(CustomConfig): pass ``` Then it will use `CustomConfig.extra` if it exists, otherwise it'll be `BaseModel.Config.extra` (which is `Extra.ignore`). Is that okay? If `config` was `None`, `CustomConfig` is the empty class. `Config(CustomConfig)` will have `extra = Extra.ignore`. Does the user expect `extra = Extra.forbid` by default? The issue says "Expected: No errors" when `config={'extra': Extra.allow}` is passed. If I want to keep the default as `Extra.forbid` but allow overriding: ```python # ... if not TYPE_CHECKING: # pragma: no branch if isinstance(config, dict): # Ensure default extra is forbid if not provided in dict if 'extra' not in config: config['extra'] = Extra.forbid CustomConfig = type('Config', (), config) # noqa: F811 elif config is not None: # If config is a class, we can't easily check and set a default attribute # unless we subclass it or modify it.
