@jacobtylerwalls I'll keep my approval, but we're missing coverage for one line. Luckily, I think a test is pretty straightforward! |

@DanielNoord that's a lot of false positives fixed in We still have some indeterminacy in I linted a relevant $ python3 -m pylint tests/.pylint_primer_tests/pandas-dev/pandas/pandas/tests/indexes/multi/test_reshape.py

Relevant: pylint-dev/astroid#1107. Maybe these changes should go there. And not backport this but get in astroid2.12/pylint2.15? With the deprecations to get rid of the extra methods. |
Ah I had been looking for that issue in Yeah, this seems like it might fit better upstream. |

I'm looking into the changelog hook error. It's strange that the result is not the same depending on the environment. Could you add the verbose option and give me the result @jacobtylerwalls ? |

":Release: 2.1\n:Date: 2018-08-01\n\nSummary -- Release highlights\n=============================\n\n* This release mostly includes fixes for bugs found after the launch of 2.0.\n\nNew checkers\n============\n\n* A new check was added, ``misplaced-format-function``.\n\n This message is emitted when pylint detects that a format function is called on non str object.\n This can occur due to wrong placement of closing bracket, e.g\n\n .. code-block:: python\n\n print('value: {}').format(123) # bad\n\n print('value: {}'.format(123)) # good\n\n\nOther Changes\n=============\n\n* ``try-except-raise`` check was demoted from an error to a warning, as part of issue #2323.\n\n* Correctly handle the new name of the Python implementation of the ``abc`` module.\n\n In Python 3.7, the ``abc`` module has both a C implementation as well as a Python one,\n but the Python implementation has a different file name that what ``pylint`` was expecting,\n resulting in some checks getting confused.\n\n* Modules with ``__getattr__`` are exempted by default from ``no-member``\n\n There's no easy way to figure out if a module has a particular member when\n the said module uses ``__getattr__``, which is a new addition to Python 3.7.\n Instead we assume the safe thing to do, in the same way we do for classes,\n and skip those modules from checking.\n\n\n* ``invalid name`` is no longer triggered for function and attribute names longer\n than 30 characters. The upper limit was removed completely.\n\n\n* Fix false-positive ``undefined-variable`` for self referential class name in lamdbas\n\n* ``no-else-return`` also specifies the type of the branch that is causing the error.\n\n* Fixed inconsistent behaviour for bad-continuation on first line of file.\n\n* Fixed a bug where ``pylint`` was not able to disable certain messages on the last line through\n the global disable option.\n\n* ``pylint`` no longer emits ``useless-return`` when it finds a single statement that is the ``return`` itself\n\n We still want to be explicit when a function is supposed to return\n an optional value; even though ``pass`` could still work, it's not explicit\n enough and the function might look like it's missing an implementation.\n\n* Fixed a bug where ``pylint`` was crashing when being unable to infer the value of an argument to ``next()``\n\n\n* ``pylint`` no longer emit ``not-an-iterable`` when dealing with async iterators.\n\n* ``pylint`` gained the ability to specify a default docstring type for when the check cannot guess the type\n\n For this we added a ``--default-docstring-type`` command line option.\n"

Type of Changes
Description
The check for
typing.TYPE_CHECKINGwas not robust against importingtypingast. Nor against importingkeyboardingastyping. This could lead to false positives forunused-import.Follow-up: we have the following plethora of utils. Would be good to standardize and deprecate some for 2.15 (not a backport task, though):
Closes #3846
