Environment data

Code Snippet

npx pyright@1.1.373 . -p ../pyrightconfig.json

from decimal import Decimal

class Foo:
    foo: Decimal | None

    def __init__(self, foo: Decimal | None):
        self.foo = foo

records: list[Foo] = [Foo(Decimal(1)), Foo(None)]

Decimal(sum((record.foo or 0) for record in records) if records else 0)

Expected behavior

Pylance should flag the errors that show up in the CLI

  /Users/tyler/Code/condor/hanaq/abacus/functions/grid_functions/FOO.py:13:9 - error: No overloads for "sum" match the provided arguments (reportCallIssue)
  /Users/tyler/Code/condor/hanaq/abacus/functions/grid_functions/FOO.py:13:13 - error: Argument of type "Generator[Decimal | int, None, None]" cannot be assigned to parameter "iterable" of type "Iterable[_SupportsSumNoDefaultT@sum]" in function "sum"
    "Generator[Decimal | int, None, None]" is incompatible with "Iterable[Decimal]"
      Type parameter "_T_co@Iterable" is covariant, but "Decimal | int" is not a subtype of "Decimal"
        Type "Decimal | int" is incompatible with type "Decimal"
          "int" is incompatible with "Decimal" (reportArgumentType)

Actual behavior

Pylance doesn't have any errors

This error is a false positive. It's due to a regression that I introduced in pyright 1.1.373 (apologies for that). I fixed it in pyright 1.1.374.

heejaechang commented 1 month ago

we will pull in 374 soon for next prelease (this wed probably)

tylerlaprade commented 1 month ago

Sure, no worries @erictraut, bugs happen sometimes. But separately there's a bug in Pylance if it doesn't exhibit the same behavior as the CLI when both are running the same Pyright version. In this case, I have both of them on 1.1.373.

tylerlaprade commented 1 month ago

@heejaechang, outside of this specific error, why is Pylance exhibiting different behavior than Pyright when both are on the same version?

erictraut commented 1 month ago

@tylerlaprade, you may find this documentation useful.

tylerlaprade commented 1 month ago

Thanks @erictraut. I verified that both are indeed using the same underlying Pyright version, and my project has a pyrightconfig.json, so that rules out two of the three possible issues. The only one remaining is the stubPath. However, if they were looking at different stubs, I would have seen many more discrepancies in the past. This seems to be isolated to whether or not this particular regression is included.

heejaechang commented 1 month ago

@tylerlaprade we need to take a look. but pylance might have some pyright changes not released yet from pyright. that sometime happens due to how we bring in pyright changes to pylance.

heejaechang commented 2 weeks ago

please re-open if this still repro with the latest pylance with pyright.

tylerlaprade commented 2 weeks ago

This still repros for me. It looks like the pyright version did not get updated in this release: https://github.com/microsoft/pylance-release/blob/main/releases/latest-release.json

debonte commented 2 weeks ago

This still repros for me. It looks like the pyright version did not get updated in this release: https://github.com/microsoft/pylance-release/blob/main/releases/latest-release.json

Please try prerelease. Yesterday's 2024.8.2 release was a hotfix for a crash bug and did not include any other changes (ex. no Pyright upgrade).

tylerlaprade commented 2 weeks ago

Thanks @debonte. Prerelease is pointing at a version of Pyright after the bugfix, so I wouldn't expect it to flag the error regardless. But I'm still getting the discrepancy when on release Pylance and using the same Pyright version for both CLI and Pylance - CLI flags the error (and fails CI), while Pylance doesn't flag the error.

debonte commented 2 weeks ago

As @heejaechang guessed above, Pylance 2024.8.1 (and 2024.8.2) is not exactly on Pyright 1.1.373. The pyright commit hash is https://github.com/microsoft/pyright/commit/ee42447964f776ef94eaf2bd307fd58ffeef0821, which is 11 commits after 1.1.373. We generally try to align Pylance's copy of Pyright exactly on a Pyright release, but this is not always possible.

Sorry for the inconvenience.

FWIW, you can see the Pyright commit hash in the Pylance log:
