protobuf gRPC python type stubs not accurately reflecting runtime

What version of protobuf and what language are you using? Version: grpcio 1.71.0 Language: Python

What operating system (Linux, Windows, ...) and version? N/A

What runtime / compiler are you using (e.g., python version or gcc version) python?

What did you do? I'm migrating the following issues over from https://github.com/grpc/grpc:

https://github.com/grpc/grpc/issues/39404
https://github.com/grpc/grpc/issues/39406
https://github.com/grpc/grpc/issues/39407

Ran stubtest on grpcio-reflection, grpcio-health-checking and grpcio-channelz. In my case it was in the context of running it on Typeshed:

Clone typeshed at or after this commit: https://github.com/python/typeshed/commit/a43e0a4c02398ea169aeb5b33c661470b2f7be5e
Copy grpc's 2.1. grpc_reflection/v1alpha/reflection_pb2.pyi over typeshed's stubs/grpcio-reflection/grpc_reflection/v1alpha/reflection_pb2.pyi 2.2. grpcio-health-checking/grpc_health/v1/health_pb2.pyi over typeshed's stubs/grpcio-health-checking/grpc_health/v1/health_pb2.pyi 2.3. grpcio-channelz/grpc_channelz/v1/channelz_pb2.pyi over typeshed's stubs/grpcio-channelz/grpc_channelz/v1/channelz_pb2.pyi
run pip install -r requirements-tests.txt
run python ./tests/stubtest_third_party.py grpcio-reflection

What did you expect to see No stubtest error for *_pb2.pyi files. Meaning they correctly reflect runtime.

What did you see instead?

`grpcio-reflection`

grpcio-reflection... (6.27 s) fail

Classes are not marked as final using the @typing.final decorator

Marking classes as final in .pyi sounds like a great idea.

The stubs indicate classes have slots, when runtime doesn't

What is the meaning of __slots__ in a stub? It looks like we're able to specify the properties manually, separate from __slots__. So I don't see the harm in removing this, but we'd need to check that this doesn't break anything internally.

Classes in the stubs are all missing the google._upb._message.MessageMeta metaclass

I consider the MessageMeta metaclass to be an internal implementation detail that should not be part of the public interface contract.

Why do stubs want the metaclass to be specified?

DESCRIPTOR is actually from google._upb._message

While the type is indeed implemented in the _message extension, its publicly accessible name is google.protobuf.descriptor.Descriptor.

It looks like that is a bit of a fib though. They are actually two separate classes, and we use a metaclass to make isinstance succeed: https://github.com/protocolbuffers/protobuf/blob/f9727e802c0b18cb7dc25c0df861df6907f3de46/python/google/protobuf/descriptor.py#L40-L52

We definitely don't want to expose the internal name google._upb._message.Descriptor, but maybe we could tweak our approach here so that the google.protobuf.descriptor.Descriptor was just an alias for google._upb._message.Descriptor.

What is the meaning of __slots__ in a stub?

I don't think there's a special meaning for stubs. Other than letting users access that attribute directly without attribute access error:

# type stubs
class MyClass:
    __slots__ = ("foo", "bar")
   foo: str
   bar: int

MyClass.__slots__  # no type-checking error

I could see a type-checker have special handling in non-strict mode: like allowing unknown attributes get/set in non-strict mode, but still disallowing it if __slots__ are set.

In any case it seems it would be incorrect here since it doesn't look like __slots__ are set at runtime.

If you deem something internal implementation and prefer not exposing it at all, that's fine. (in some cases it could introduce inconsistencies in isinstance checks between what static tools see and what happens at runtime)

Why do stubs want the metaclass to be specified?

Stubtest specifically checks all the differences between definition and runtime. If a metaclass doesn't actually affect the visible signature of a class, and should be completely transparent to any intended runtime use, then feel free to not include it if it's easier.

In typeshed, where this is more of a concern for us, we try to match runtime as closely as we can, and will expose some private API only when necessary to do so. It's easier to not have to guess at the original intents. As a maintainer of your project, you're better placed to know if that's something you care about, or would prefer hiding.

I could see a type-checker have special handling in non-strict mode: like allowing unknown attributes get/set in non-strict mode, but still disallowing it if slots are set.

I discovered this to be the case. In some cases (not with mypy), I found that unknown attributes were not checked unless I added __slots__ = ().

The addition of __slots__ = () also causes issues in some linters (PyCharm, in my case) where all fields are regarded as read-only and undefined.

class Nya(_message.Message):
    __slots__ = ()
    MEOW_FIELD_NUMBER: _ClassVar[int]
    meow: int
    def __init__(self, meow: _Optional[int] = ...) -> None: ...

...

nya = Nya()
nya.meow = 1

# 'Nya' object attribute 'meow' is read-only 
# 'Nya' object has no attribute 'meow'

which is technically the correct behavior, slots is defined, and it is empty indicating that no field is visible.

Is there any way to make both type checkers happy? It sounds like the Python type checking semantics are not always consistent across tools.

I have to agree that this doesn't seem like the correct approach. Tested with protoc 33.1, I get a christmas tree of warnings. It (curiously) throws both of these for each field:

'ResponseHeader' object attribute 'error_code' is read-only 
'ResponseHeader' object has no attribute 'error_code'

If anyone can propose a solution that makes both mypy and PyCharm happy, we'd be happy to accept a contribution.

It's interesting that the change to protobuf 33 is described to fix mypy because I'm having the opposite experience -- mypy worked prior to the change, but afterwards I'm getting the following:

path/to/my/file.py:662: error: Trying to assign name "user" that is not in "__slots__"
of type "my_proto.ProtoClass"  [misc]
            p.user = "user-value"

Tried this with mypy from 1.16 to 1.19 and all produces the same outcome. @haberman was this what you were trying to fix, or is this a different manifestation of the issue here?

It's been a while since I looked at this, so my memory doesn't help. But looking at https://github.com/protocolbuffers/protobuf/issues/21691#issuecomment-3185957672, it seems that my testing showed that a statement like msg.nonexistent_field= 1 was not flagged as an error by mypy unless I added __slots__ = ().

FWIW, having adding __slots__ to stubs is not one of the discrepancies I noted in my original issue. I only mentioned classes that have __slots__ in the stubs when it's not present at runtime.

https://github.com/protocolbuffers/protobuf/pull/23156 does not solve anything I mentioned, in fact it worsens it. If __slots__ aren't present at runtime, then stubs should not have __slots__ = ().

"Lack of __slots__" and "__slots__ set to an empty tuple" are not the same thing at all. One says any attribute can be set, the other says no attribute can be set (and class attributes are readonly).

We have to leave an empty __slots__ = () in place, as opposed to removing it entirely, because that's the only way to ensure that pytype will continue to error out if an unknown member is read or written.

pytype not having a strict mode to detect unknown attributes is not a valid reason imo to lie about __slots__, especially given that pytype development is no longer supported

It's been a while since I looked at this, so my memory doesn't help. But looking at #21691 (comment), it seems that my testing showed that a statement like msg.nonexistent_field= 1 was not flagged as an error by mypy unless I added __slots__ = ().

See https://mypy.readthedocs.io/en/stable/error_code_list.html#check-that-attribute-exists-attr-defined

Unless you meant pytype, in which case, see my previous comment.

Is there any major objection to reverting this change for the time being? It seems the immediately available options are:

"__slots__ includes all settable fields in the pyi file" (the case before 33.0)
- pro: Prevents setting fields which don't exist on the proto
- con: creates errors generating typeshed because __slots__ is not actually set on the class itself
"__slots__ is not set at all"
- pro: .pyi file is true to the actual .py file
- con: no errors when setting fields which don't exist

and we're currently in the situation:

"__slots__ is set to ()"
- pro: prevents setting fields which don't exist on the proto
- con: breaks typechecking in mypy, pycharm (reportedly), and doesn't fix the underlying issue with typeshed

My suggestion would be to revert https://github.com/protocolbuffers/protobuf/pull/23156 and go back to the original situation in the interim while progress is made on fixing the typeshed issue.

@jasonkuster thanks for the summary!

If reverting https://github.com/protocolbuffers/protobuf/pull/23156 would be the most helpful for the time being, I'm happy to do that.

Dec 05 '25 22:12 haberman

Yeah if you don't object it seems like the best short term option (and I see a 👍 from the OP on my message so it seems like we have some agreement on that). Thanks!

Dec 05 '25 23:12 jasonkuster

Would it be better from your perspective if we removed __slots__ entirely?

The example given at https://mypy.readthedocs.io/en/stable/error_code_list.html#check-that-attribute-exists-attr-defined suggests that you can still get attr-defined errors even if __slots__ is not set (which is what we want).

Do we know if PyCharm will do the same?

I have created these two pull requests, and can work to land whichever one seems more desirable:

https://github.com/protocolbuffers/protobuf/pull/24787
https://github.com/protocolbuffers/protobuf/pull/24790

Dec 10 '25 20:12 haberman

I'd suggest:

submit the rollback, and if possible release 33.3 (since our understanding now is that this is a "regression"-ish in 33.x).
evaluate removing __slots__ entirely as a follow-up (for 34.0+), since doing so probably requires a bit more investigation.

Dec 10 '25 21:12 jasonkuster

Hi @haberman I see the first PR merged, thanks so much! Are you willing/able to cut a 33.3 release containing that PR? I'm trying to prep my codebase for bazel 9 which requires >=33.0, and I'm hoping to use a released version of protobuf rather than pinning to a commit if possible. :) If there's anything I can do to help with that please let me know.

Dec 16 '25 18:12 jasonkuster

Hi @jasonkuster, yes, v33.3 is coming soon (hopefully this week), and will include this change.

Dec 16 '25 18:12 haberman

Wonderful news, thanks so much 😁
