| | | | | | | | | | | | | | | | | | | missing-any-param-doc (#5097) * Correctly identify parameters with no doc and add new message This commit fixes the problem where non documented parameters where not being identified properly. Also, it adds a new message called ``missing-any-param-doc`` for when a function has no parameter and type doc at all. Adds new test cases for the ``missing-param-doc`` and ``missing-type-doc`` messages and tests for the new message ``missing-any-param-doc``. * Replace old messages with the new one where needed Fix pylint's code where the new message where needed in other files instead of triggering both missing-param-doc and missing-type-doc.

* Improve and flatten ``unused-wildcard-import`` message (#5110)Daniël van Noord2021-10-041-0/+4
| | | | | | | | | * Improve and flatten ``unused-wildcard-import`` message Instead of reporting all unused imports, the checker now emits one single message for all unused imports with a stylized string containing all imports. This closes #3859 * Add tests for string formation

* Make ``global-variable-not-assigned`` check local scope (#4990)Daniël van Noord2021-09-111-0/+6
| | | | | | | | | | | | * Make ``global-variable-not-assigned`` check local scope This checker now checks whether the names after the global keyword are reassigned in the local scope. This closes #1375 * Make ``global-variable-not-assigned`` check functions This checker now also checks function defintions in the module and local scope This closes #330 Co-authored-by: Pierre Sassoulas <pierre.sassoulas@gmail.com>
* Fix bug with cache's parent directory not existing (#4988)Daniël van Noord2021-09-101-0/+4
| | | | | | By changing the function used to create the cache from ``os.mkdir`` to ``os.makedirs`` we now handle non-existing parent directories correctly. This closes #4900
* Make ``min-similarity-lines == 0`` stop similarity check (#4970)Daniël van Noord2021-09-071-0/+4
| | | | | | | | * Make ``min-similarity-lines == 0`` stop similarity check This makes it so that setting ``min-similarity-lines`` to zero exit the similarity code checker with a successful exit. This closes #4901 Co-authored-by: Marc Mueller <30130371+cdce8p@users.noreply.github.com>

* Fix false positive ``superfluous-parens`` for tuplesDaniël van Noord2021-09-011-0/+4
| | | | | | Tuples can be created with inner tuples. This creates double parenthesis which we flagged incorrectly. This closes #4907
* Extend ``unspecified-encoding`` checkerDaniël van Noord2021-09-011-0/+5
| | | | | | The ``unspecified-encoding`` checker now also checks calls to ``pathlib.Path().read_text()`` and ``pathlib.Path().write_text()`` This closes #4945
* Remove the python3 porting mode from the codebasePierre Sassoulas2021-09-011-0/+5
| | | | | | It's possible to use the python3 porting checker from an older pylint version. But it's not evolving anymore and was costing resource to maintain.
* Fix false positive `dict-iter-missing-items` for tuple keys (#4939)Daniël van Noord2021-08-311-0/+4
| | | | | | This fixes a false positive emitted for dictionaries that contain only tuples as keys. This makes unpacking the dictionary without calling `.items()` valid. This closes #3283
* Fix false positive ``protected-access`` in typing (#4937)Daniël van Noord2021-08-312-5/+8
| | | | | | | | * Fix false positive ``protected-access`` in typing Class functions can return protected members which can then be passed as arguments to other functions. When using type hints in function definitions these raised a message which they shouldn't do.
* Fix false positive for `function-redefined` for simple type annotationsDaniël van Noord2021-08-311-0/+4
| | | | Closes #4936
* Emit a correct invalid-name message when using multi-naming style. (#4924)Yilei "Dolee" Yang2021-08-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | * Emit a correct invalid-name message when using multi-naming style. Previously, given `--function-rgx=(?:(?P<UP>[A-Z]+)|(?P<down>[a-z]+))$` and the code: ``` def FOO(): pass def UPPER(): pass def lower(): pass ``` It would emit a message: ``Function name `lower` doesn't conform to '(?:(?P<UP>[A-Z]+)|(?P<down>[a-z]+))$' pattern [invalid-name]``. The message is misleading as `lower` *does* conform to `(?:(?P<UP>[A-Z]+)|(?P<down>[a-z]+))$`. It's just not the prevalent group "UP". After this commit, the message becomes: ``Function name `lower` doesn't conform to UP group in the '(?:(?P<UP>[A-Z]+)|(?P<down>[a-z]+))$' pattern [invalid-name]`` Co-authored-by: Pierre Sassoulas <pierre.sassoulas@gmail.com>

* Implement basic control flow checks for ``consider-using-with`` (#4929)Andreas Finkler2021-08-301-0/+3
| | | | | | | * Add some control flow checks to consider-using-with in order to handle assignments in different branches * Use existing function from ``astroid`` to determine whether two statements are exclusive * Add unit tests for new utility methods * Add ChangeLog and whatsnew entry
* Add ``Consider-using-f-string`` checker (#4796)Daniël van Noord2021-08-301-0/+4
| | | | | | | | | | | | | | | | * Add ``consider-using-f-string`` checker This adds a checker for normal strings which are formatted with ``.format()`` or '%'. The message is a convention to nudge users towards using f-strings. This closes #3592 * Update pylint code to use f-strings After adding `consider-using-f-strings` the codebase showed numerous cases of formatting which could be f-strings. This commit changes most of these to become f-strings, or adds ignores. * Apply suggestions from code review Co-authored-by: Pierre Sassoulas <pierre.sassoulas@gmail.com>
* Move back to a dev version following 2.10.0 releasePierre Sassoulas2021-08-202-0/+22
