Pylint: RecursionError: maximum recursion depth exceeded while calling a Python object

[xorb0ss]

Steps to reproduce

1.

import pandas as pd

def func(col: pd.Timestamp):
    load = pd.to_datetime(col) - pd.DateOffset(years=2)
    sql = “””SELECT {col} FROM *”””.format(col=load)

Current behavior

Crashes with RecursionError: maximum recursion depth exceeded while calling a Python object

Expected behavior

Not to crash

pylint --version output

pylint 2.5.3
astroid 2.4.2
Python 3.8.2
GCC 9.3.0

extra notes

This crash does not occur with pylint==2.3.1 & astroid==2.2.5 similar to #3318

[Choc13]

We are also experiencing this with the same versions of pylint, astroid and python as listed above.

For us it seems to have started happening when pandas updated from 1.0.5 to 1.1.0.

[AWhetter]

I can't reproduce this, although pylint does get stuck at some point in the linting process so it may well be recursing deep at that point. My recursion limit is at 1000:

>>> import sys
>>> print(sys.getrecursionlimit())
1000

[mberr]

I can't reproduce the error with the initial script, however I have a slightly different (minimal) script causing the same error

import pandas

def process(dfa: pandas.DataFrame, dfb: pandas.DataFrame) -> pandas.DataFrame:
   return pandas.merge(dfa, dfb)

$ pylint --disable=all --enable=F,E mwe.py
[...]
RecursionError: maximum recursion depth exceeded

@mberr thanks for this update. I can reproduce the bug with your snippet.

pylint 2.6.1-dev1
astroid 2.4.3

@mberr this issue is similar to #2843 and #2811. Thanks to @brycepg and PyCQA/astroid#804 it is solved in the master branch of astroid.
I haved tested your snippet with the astroid master branch and the RecursionError doesn't appear any more. I close this issue.

[adam-azarchs]

I and can still reproduce this in python 3.7 and astroid at current master.

[hippo91]

@adam-azarchs thanks for your feedback. Can you give us a snippet of the problem please?

[adam-azarchs]

Code similar to that in https://github.com/PyCQA/pylint/issues/3746#issuecomment-702066477 using pd.merge reproduces it with pandas version 0.24.2. I'm expecting we'll probably resolve the issue by updating pandas to a more recent version once our team has the bandwidth to do that, but would be nice to have the underlying issue fixed on the pylint side in case it pops up in other contexts. I can come back with a more complete reproducer if need be when I have more time.

I'm seeing this problem with the python:3.8 Docker file: https://gist.github.com/bnsh/b959f91a33ac014e41c1692e9269e1e7

The gist shows the output I get.

@adam-azarchs in fact the pandas version you use is quite old. It would be nice if you could test with a more recent version.
@bnsh you problem is a duplicate of #3977.
