Thanks for the issue but I can't seem to reproduce it.

Can you include more of the code?

rlippmann commented 1 year ago

I tried your sample code, too, and it's giving me the same warning.

rchiodo commented 1 year ago

I'm still not reproing that specific error. Your example doesn't include a bunch of things though so maybe that's why. But if my example repros, that's easier to diagnose.

Can you show the exact error and where it's coming from?

rlippmann commented 1 year ago

(not sure why it thinks the static method is part of init)

rchiodo commented 1 year ago

Maybe it's not picking up the right definition for staticmethod. What do you get when you hover over staticmethod:

erictraut commented 1 year ago

I suspect there's something corrupt with either your pylance install, your settings, or your virtual environment. Let's see if we can eliminate some of those. Could you try to repro the problem with a fresh project and a fresh virtual environment?

rlippmann commented 1 year ago

The same thing you get. If I change the static method above init, I get the same problem.

rlippmann commented 1 year ago

It goes away with a fresh project/virtualenv

rchiodo commented 1 year ago

Can you install all the same modules in the new virtual env and see if it repros? Trying to see if there's a specific package causing the problem or if it's in your source.

rlippmann commented 1 year ago

I created an entirely new virtualenv in the original project directory, and it repros.

rlippmann commented 1 year ago

Ok, closed the folder and reopened, and it went away.

rchiodo commented 1 year ago

Perhaps it is something in the original virtual environment then.

You should be able to list the contents of each (assuming they're venvs) and diff the pip list output.

rlippmann commented 1 year ago

I'm doing development for home assistant, so it's a pretty large set of packages.

rchiodo commented 1 year ago

If you list them here, we can try and reproduce the problem.

rlippmann commented 1 year ago

As an aside, issue https://github.com/microsoft/pylance-release/issues/4832 went away with the environment change.

Thanks. I installed everything in that list except for your custom build of homeassistant (which looked like it was pointing to your custom build).

Here's the requirements.txt I used. requirements.txt

I cannot reproduce with a simple project with that requirements.txt installed. So maybe it's your homeassistant build, or maybe it's something in the project intersecting with the other things in the venv.

Can you try installing the requirements.txt into a fresh venv and see if it reproduces?

I have the same issue. Pylance 2023.9.10 reports warning on perfectly valid code while 2023.8.50 works as expected.

I have this kind of errors on @staticmethod

Argument of type "(c1: Cache, c2: Cache) -> Cache" cannot be assigned to parameter "__f" of type "() -> _R_co@staticmethod" in function "__init__"
  Type "(c1: Cache, c2: Cache) -> Cache" cannot be assigned to type "() -> _R_co@staticmethod"

Also these errors on list element access

Argument of type "Literal[-1]" cannot be assigned to parameter "__s" of type "slice" in function "__getitem__"
  "Literal[-1]" is incompatible with "slice"

pathlib.Path.cwd() raises a warning Type of "cwd" is partially unknown Type of "cwd" is "() -> Unknown" since @classmethod in pathlib.py also raises the same error as @staticmethod in my code.

I don't have standard diagnostics overrides, here they are:

@TheCaptainCat, I'm guessing that if you create a new venv and populate it with these requirements, the problem will go away. Could you test that hypothesis? I just tried to repro your issue with the above requirements.txt dependencies, and I wasn't able to.

If my theory is correct, then there's something else in your current venv (perhaps some corruption) that is triggering this behavior in pylance, and it would be good to understand what that is.

@erictraut, I tried a new venv, even tried clearing the WSL server cache. But that didn't work. I'll try setting everything up on another system and I'll get back here.

TheCaptainCat commented 1 year ago

@erictraut So you were right, I installed a fresh Fedora and reinstalled all requirements and VS extensions just like my regular setup and everything works as intended.

So it seems to be a bad cache, but does someone knows how to completely clear that cache. I use vscode-insiders on WSL.

I must add that Pylance had become extremely slow and was re-analysing every file in the project on every keystroke, making work very slow and frustrating. That seems to be gone too with a fresh install.

Something weird is going on. This sounds similar to this issue: https://github.com/microsoft/pylance-release/issues/4889

stevesimmons commented 1 year ago

For the last three weeks, I've been getting the same issue on staticmethod and classmethod and on some list operations. This is on old code that type-checked correctly for months. The type diagnostics in Pylance's messages match those in this issue and the couple of other related ones.

Here is a minimal example to reproduce:

class MyClass:
    @classmethod    # Pylance gives red squiggle under "classmethod"
    def hello(cls):
        print("hello")

I have tried reinstalling the Pylance VSC extension and switching to prerelease. Not tried reinstalling venv yet.

Update: Appears to be fixed on reinstalling the venv

av1m commented 1 year ago

I had the exact same problem @stevesimmons I confirm, I have just reinstalled venv and the dependencies, I no longer have these errors.

rchiodo commented 1 year ago

Closing given that the fix is to reinstall your venv. Something may have been installing something that was interfering with our type stubs, but is no longer installing those extra bits.

If somebody can reproduce this with a fresh venv, please add a comment with directions on installing. Thanks.
