Crash Report

While I was having no problems with MyPy 1.10, with MyPy 1.11.0, 1.11.1 I get segmentation faults, and an exception with the code installed as:

pip3 install git+https://github.com/python/mypy@fe15ee69b9225f808f8ed735671b73c31ae1bed8

By avoiding the segfaults, I get a KeyError: 'expr'

To Reproduce

This results from running MyPy on a large code base that makes heavy use of TypeVarTuple and Unpack. I cannot isolate the issue but this can be reproduced within the following PR:

https://github.com/static-frame/static-frame/pull/966

Your Environment

• Mypy version used: 1.11.0, 1.11.1
• Mypy command-line flags: mypy --strict
• Mypy configuration options from mypy.ini (and other config files): https://github.com/static-frame/static-frame/blob/e235c34c1a25a97a36e24e5c584049bd2df31ebb/pyproject.toml#L26
• Python version used: 3.11
• Operating system and version: Ubuntu 20.04.3 LTS

Did you somehow managed to use mypy cache from an old mypy version? I thought mypy is smart enough to not do this, unless you are doing something tricky.

[flexatone]

Hi @ilevkivskyi , thank you for looking at this.

Not trying to do anything tricky! I first found the segfault in CI on a clean GitHub Action run.

Running it locally again after explicitly removing .mypy_cache, I do now get a different exception. The exception is long due to the recursion issue; these are the last lines.

Happy to help investigate as needed.

RecursionError: maximum recursion depth exceeded

OK, now this is interesting. I have an idea of what may be going on, but it may take a while to find repro. Mypy should print file name and line number that caused the crash before the start of the traceback. You can try using this to find a minimal repro.

Thanks, @ilevkivskyi , for the note on the line number.

I have been able to create reproduceable snippet, below. This code has been around and passing for some time, at least on MyPy 1.9 and 1.10, and I have confirmed again it passes on 1.10. If I remove the recursive union component, the exception goes away.

import typing as tp

TLabel = tp.Union[
        tp.Hashable,
        int,
        bool,
        float,
        complex,
        str,
        bytes,
        None,
        tp.Tuple['TLabel'],
]

TLocSelectorNonContainer = tp.Union[
        TLabel,
        slice,
        tp.List[TLabel],
        ]

def is_slice(value: TLocSelectorNonContainer) -> bool:
    return value.__class__ is slice

Note that the following, simpler example, still using the recursive union, passes without exception.

import typing as tp

TLabel = tp.Union[
        tp.Hashable,
        int,
        bool,
        float,
        complex,
        str,
        bytes,
        None,
        tp.Tuple['TLabel'],
]

def is_none(value: TLabel) -> bool:
    return value is None

[ilevkivskyi]

Yeah, we recently switched tuple fallbacks from joins to unions, this obviously causes this issue.

Btw while I am working on this, using tp.Tuple['TLabel', ...] (i.e. variable length tuple) will likely fix the crash for you (depending on how much this snippet has been simplified).

[flexatone]

Thank you for pointing that out: tp.Tuple['TLabel', ...] was actually my intention all along.

Making that change fixes the crash for me: much appreciated!

[ilevkivskyi]

In the meantime a bit simpler repro is

from typing import Tuple, Union, Hashable, List

TLabel = Union[Hashable, Tuple[TLabel]]
TLabels = Union[TLabel, List[TLabel]]

x: TLabel
xs: TLabels = [x]
