Output types broken as input types InventoryConfigurationOutputTypeDef, LifecycleRuleOutputTypeDef about mypy_boto3_builder HOT 4 OPEN

Hello! THank you for the report.

Looks like this output type is not compatible with the corresponding input type. I will take a look.

from mypy_boto3_builder.

Unfortunately, these types are incompatible. Does rewriting code as

new_rule: LifecycleRuleOutputTypeDef = {
    'ID': 'rule_name',
    'Expiration': {'Days': 1},
    'Filter': {'Prefix': 'prefix'},
    'NoncurrentVersionExpiration': {'NoncurrentDays': 1},
    'AbortIncompleteMultipartUpload': {'DaysAfterInitiation': 1},
    'Status': 'Enabled',
}

work for you?

from mypy_boto3_builder.

It does not seem to help. We are going to use # type: ignore for now:

rules: list[LifecycleRuleTypeDef]
rules = client.get_bucket_lifecycle_configuration( # type: ignore[assignment]
    Bucket='bucket_name'
)['Rules']

Not in the example above but the next line we have is:

config: BucketLifecycleConfigurationTypeDef = {'Rules': rules}

And mypy was failing with this error:

Incompatible types (expression has type "list[LifecycleRuleOutputTypeDef]", TypedDict item "Rules" has type "Sequence[LifecycleRuleTypeDef]")  [typeddict-item] (1,955:64)

from mypy_boto3_builder.

As far as I understand, before you used mypy-boto3-s3 1.34.65. There was a bug fixed in #244 that incompatible output shapes were used instead of separating output and input shapes in case of conflict.

For this particular shape input and output definitions are not compatible. So, type: ignore looks like the easiest solution.

pyright changes the way it compares TypedDicts in https://github.com/microsoft/pyright/releases/tag/1.1.333 release. So, since TypedDicts are invariant, output TypedDict cannot be assigned to an input TypedDict.

I will cross-check again tomorrow.
