@pjbull Important information is here:

microsoft/pyright#3117 (comment)

[pjbull]

Thanks for sharing those details.

Does the workaround mentioned resolve the reported pylance error at least? That would be good for other folks finding this issue to know.

Your pyright config is relevant here. I can reproduce this with"useLibraryCodeForTypes": truebut not with "useLibraryCodeForTypes": false.

It's still the case that we'd accept a PR that makes pyright pass and adds that verification to CI. That said, if I'm reading the issue you linked right, it seems that typing any of the properties that use the dispatching to the Path version may be tricky.

[hmc-cs-mdrissi]

I would type hint properties normally and for _dispatch_to_path just do,

def _dispatch_to_path(self, func: str, *args: object, **kwargs: object) -> Any:
    ...

dispatch_to_path is doing too much magic to be understandable for a static type checker. Mostly getattribute and how literal string value of func can change return type in a variety of ways. After you effectively ignore _dispatch_to_path you can add hints for each property normally like,

@property
def name(self) -> str:
    ...

@pjbull

When I disable this setting:

I don't have previous error anymore, but I don't have anything, no autocompletion, nothing:

So this is fixing it, but at the same time it is disabling so much convenience (auto-completion). So I will keep this setting turned on ;)

[pjbull]

Down to 48 errors on latest code with #298 and other improvements, next time someone looks at making pyright pass. I get pretty decent hinting in vscode currently, just for the record.

I discovered one issue, described here: microsoft/pyright#4896

If you think that CloudPath.init should accept any CloudPath argument, then you should report the bug to the library maintainer. If the CloudPath.init type information is correct, then you must pass an S3PathWrapper object to it, not any CloudPath.

I am reporting here, because I think it is issue in cloudpathlib.

[pjbull]

@karolzlot Do you know what the required change would look like? It does seem that CloudPath should be initializable from any CloudPath object (including S3Path, GSPath, etc.), but S3Path should just work with S3Path. That makes me think maybe the issue is more about how the wrapper class in your example is architected than a library problem, but maybe I am missing something.

[jayqi]

@karolzlot, a few thoughts here from looking at your example in microsoft/pyright#4896:

First, as @pjbull said, S3Path intentionally does not accept any CloudPath object as an argument—it should only work with S3Path. I think you actually intend something like:

cloud_path: Union[str, S3Path]

However, this will still result in a type error from pyright, because super().__init__ is expecting cloud_path: Union[str, S3PathWrapper]. As was correctly explained in this comment in the other thread, the inherited super().__init__ is designed only to expect objects of the self type.

It may be possible that we could change S3Path to explicitly initialize from instances of S3Path rather than a self class. That would mean subclasses would in general inherit an __init__ that takes S3Path, like what you are doing. However, I'm not convinced this is a sensible change to make—in general, I would expect more often that subclasses add more behavior that would be missing from the parent S3Path and so it wouldn't make sense to be able to initialize from S3Path.

I don't know much about what you're trying to accomplish since you've only shared a minimal example with the interface. However, the fact that you named your class "Wrapper" suggests that subclassing isn't the best approach. You may want a different implementation that stores an instance of S3Path as an attribute (that actually wraps S3Path).

[karolzlot]

@pjbull
@jayqi

Sorry for confusion with CloudPath, I only need S3Path.

It's possible that this suggestion with using S3Path object as attribute is right approach, I will try it, thanks!
What I did: I added custom download method for S3Path object, because the one provided by cloudpathlib is not fast enough.

---

My understanding of this issue isn't very good, maybe cloudpathlib really doesn't need changes in this regard. I can't recommend anything, because I feel those concepts are still too difficult for me.

[chopeen]

PR #330 will solve this issue, right?

[karolzlot]

I will try it once new version with this change is released. I think it will solve it :)

[pjbull]

0.15.0 is released if you want to give it a shot! https://pypi.org/project/cloudpathlib/

Going to leave this issue open since we still only pass mypy and not pyright with the default settings.
