[pyup-bot]

This PR updates pylint from 2.4.2 to 2.6.2.

Changelog

### 2.6.1 ``` =========================== * Astroid version has been set as < 2.5 Close 4093 ``` ### 2.6.0 ``` =========================== Release date: 2020-08-20 * Fix various scope-related bugs in ``undefined-variable`` checker Close 1082, 3434, 3461 * bad-continuation and bad-whitespace have been removed, black or another formatter can help you with this better than Pylint Close 246, 289, 638, 747, 1148, 1179, 1943, 2041, 2301, 2304, 2944, 3565 * The no-space-check option has been removed. It's no longer possible to consider empty line like a `trailing-whitespace` by using clever options Close 1368 * ``missing-kwoa`` is no longer emitted when dealing with overload functions Close 3655 * mixed-indentation has been removed, it is no longer useful since TabError is included directly in python3 Close 2984 3573 * Add `super-with-arguments` check for flagging instances of Python 2 style super calls. * Add an faq detailing which messages to disable to avoid duplicates w/ other popular linters * Fix superfluous-parens false-positive for the walrus operator Close 3383 * Fix `fail-under` not accepting floats * Fix a bug with `ignore-docstrings` ignoring all lines in a module * Fix `pre-commit` config that could lead to undetected duplicate lines of code * Fix a crash in parallel mode when the module's filepath is not set Close 3564 * Add `raise-missing-from` check for exceptions that should have a cause. * Support both isort 4 and isort 5. If you have pinned isort 4 in your projet requirements, nothing changes. If you use isort 5, though, note that the `known-standard-library` option is not interpreted the same in isort 4 and isort 5 (see the migration guide in isort documentation for further details). For compatibility's sake for most pylint users, the `known-standard-library` option in pylint now maps to `extra-standard-library` in isort 5. If you really want what `known-standard-library` now means in isort 5, you must disable the `wrong-import-order` check in pylint and run isort manually with a proper isort configuration file. Close 3722 ``` ### 2.5.4 ``` =========================== * Fix a crash caused by not guarding against `InferenceError` when calling `infer_call_result` Close 3690 * Fix a crash in parallel mode when the module's filepath is not set Close 3564 ``` ### 2.5.3 ``` =========================== Release date: 2020-06-8 * Fix a regression where disable comments that have checker names with numbers in them are not parsed correctly Close 3666 * `property-with-parameters` properly handles abstract properties Close 3600 * `continue-in-finally` no longer emitted on Python 3.8 where it's now valid Close 3612 * Fix a regression where messages with dash are not fully parsed Close 3604 * In a TOML configuration file, it's now possible to use rich (non-string) types, such as list, integer or boolean instead of strings. For example, one can now define a *list* of message identifiers to enable like this:: enable = [ "use-symbolic-message-instead", "useless-suppression", ] Close 3538 * Fix a regression where the score was not reported with multiple jobs Close 3547 * Protect against `AttributeError` when checking `cell-var-from-loop` Close 3646 ``` ### 2.5.2 ``` =========================== Release date: 2020-05-05 * ``pylint.Run`` accepts ``do_exit`` as a deprecated parameter Close 3590 ``` ### 2.5.1 ``` =========================== Release date: 2020-05-05 * Fix a crash in `method-hidden` lookup for unknown base classes Close 3527 * Revert pylint.Run's `exit` parameter to ``do_exit`` This has been inadvertently changed several releases ago to ``do_exit``. Close 3533 * ``no-value-for-parameter`` variadic detection has improved for assign statements Close 3563 * Allow package files to be properly discovered with multiple jobs Close 3524 * Allow linting directories without `__init__.py` which was a regression in 2.5. Close 3528 ``` ### 2.5.0 ``` =========================== Release date: 2020-04-27 * Fix a false negative for ``undefined-variable`` when using class attribute in comprehension. Close 3494 * Fix a false positive for ``undefined-variable`` when using class attribute in decorator or as type hint. Close 511 Close 1976 * Remove HTML quoting of messages in JSON output. Close 2769 * Adjust the `invalid-name` rule to work with non-ASCII identifiers and add the `non-ascii-name` rule. Close 2725 * Positional-only arguments are taken in account for ``useless-super-delegation`` * ``unidiomatic-typecheck`` is no longer emitted for ``in`` and ``not in`` operators Close 3337 * Positional-only argument annotations are taken in account for ``unused-import`` Close 3462 * Add a command to list available extensions. * Allow used variables to be properly consumed when different checks are enabled / disabled Close 3445 * Fix dangerous-default-value rule to account for keyword argument defaults Close 3373 * Fix a false positive of ``self-assigning-variable`` on tuple unpacking. Close 3433 * ``no-self-use`` is no longer emitted for typing stubs. Close 3439 * Fix a false positive for ``undefined-variable`` when ``__class__`` is used Close 3090 * Emit ``invalid-name`` for variables defined in loops at module level. Close 2695 * Add a check for cases where the second argument to `isinstance` is not a type. Close 3308 * Add 'notes-rgx' option, to be used for fixme check. Close 2874 * ``function-redefined`` exempts function redefined on a condition. Close 2410 * ``typing.overload`` functions are exempted from docstring checks Close 3350 * Emit ``invalid-overridden-method`` for improper async def overrides. Close 3355 * Do not allow ``python -m pylint ...`` to import user code ``python -m pylint ...`` adds the current working directory as the first element of ``sys.path``. This opens up a potential security hole where ``pylint`` will import user level code as long as that code resides in modules having the same name as stdlib or pylint's own modules. Close 3386 * Add `dummy-variables-rgx` option for `_redeclared-assigned-name` check. Close 3341 * Fixed graph creation for relative paths * Add a check for asserts on string literals. Close 3284 * `not in` is considered iterating context for some of the Python 3 porting checkers. * A new check `inconsistent-quotes` was added. * Add a check for non string assignment to __name__ attribute. Close 583 * `__pow__`, `__imatmul__`, `__trunc__`, `__floor__`, and `__ceil__` are recognized as special method names. Close 3281 * Added errors for protocol functions when invalid return types are detected. E0304 (invalid-bool-returned): __bool__ did not return a bool E0305 (invalid-index-returned): __index__ did not return an integer E0306 (invalid-repr-returned): __repr__ did not return a string E0307 (invalid-str-returned): __str__ did not return a string E0308 (invalid-bytes-returned): __bytes__ did not return a string E0309 (invalid-hash-returned): __hash__ did not return an integer E0310 (invalid-length-hint-returned): __length_hint__ did not return a non-negative integer E0311 (invalid-format-returned): __format__ did not return a string E0312 (invalid-getnewargs-returned): __getnewargs__ did not return a tuple E0313 (invalid-getnewargs-ex-returned): __getnewargs_ex__ did not return a tuple of the form (tuple, dict) Close 560 * ``missing-*-docstring`` can look for ``__doc__`` assignments. Close 3301 * ``undefined-variable`` can now find undefined loop iterables Close 498 * ``safe_infer`` can infer a value as long as all the paths share the same type. Close 2503 * Add a --fail-under <score> flag, also configurable in a .pylintrc file. If the final score is more than the specified score, it's considered a success and pylint exits with exitcode 0. Otherwise, it's considered a failure and pylint exits with its current exitcode based on the messages issued. Close 2242 * Don't emit ``line-too-long`` for multilines when `disable=line-too-long` comment stands at their end Close 2957 * Fixed an ``AttributeError`` caused by improper handling of ``dataclasses`` inference in ``pyreverse`` Close 3256 * Do not exempt bare except from ``undefined-variable`` and similar checks If a node was wrapped in a ``TryExcept``, ``pylint`` was taking a hint from the except handler when deciding to emit or not a message. We were treating bare except as a fully fledged ignore but only the corresponding exceptions should be handled that way (e.g. ``NameError`` or ``ImportError``) Close 3235 * No longer emit ``assignment-from-no-return`` when a function only raises an exception Close 3218 * Allow import aliases to exempt ``import-error`` when used in type annotations. Close 3178 * ``Ellipsis` is exempted from ``multiple-statements`` for function overloads. Close 3224 * No longer emit ``invalid-name`` for non-constants found at module level. Pylint was taking the following statement from PEP-8 too far, considering all module level variables as constants, which is not what the statement is saying: `Constants are usually defined on a module level and written in all capital letters with underscores separating words.` Close 3111 Close 3132 * Allow ``implicit-str-concat-in-sequence`` to be emitted for string juxtaposition Close 3030 * ``implicit-str-concat-in-sequence`` was renamed ``implicit-str-concat`` * The ``json`` reporter no longer bypasses ``redirect_stdout``. Close 3227 * Move ``NoFileError``, ``OutputLine``, ``FunctionalTestReporter``, ``FunctionalTestFile``, ``LintModuleTest`` and related methods from ``test_functional.py`` to ``pylint.testutils`` to help testing for 3rd party pylint plugins. * Can read config from a setup.cfg or pyproject.toml file. Close 617 * Fix exception-escape false positive with generators Close 3128 * ``inspect.getargvalues`` is no longer marked as deprecated. * A new check ``f-string-without-interpolation`` was added Close 3190 * Flag mutable ``collections.*`` utilities as dangerous defaults Close 3183 * ``docparams`` extension supports multiple types in raises sections. Multiple types can also be separated by commas in all valid sections. Closes 2729 * Allow parallel linting when run under Prospector * Fixed false positives of ``method-hidden`` when a subclass defines the method that is being hidden. Closes 414 * Python 3 porting mode is 30-50% faster on most codebases * Python 3 porting mode no longer swallows syntax errors Closes 2956 * Pass the actual PyLinter object to sub processes to allow using custom PyLinter classes. PyLinter object (and all its members except reporter) needs to support pickling so the PyLinter object can be passed to worker processes. * Clean up setup.py Make pytest-runner a requirement only if running tests, similar to McCabe. Clean up the setup.py file, resolving a number of warnings around it. * Handle SyntaxError in files passed via ``--from-stdin`` option Pylint no longer outputs a traceback, if a file, read from stdin, contains a syntaxerror. * Fix uppercase style to disallow 3+ uppercase followed by lowercase. * Fixed ``undefined-variable`` and ``unused-import`` false positives when using a metaclass via an attribute. Close 1603 * Emit ``unused-argument`` for functions that partially uses their argument list before raising an exception. Close 3246 * Fixed ``broad_try_clause`` extension to check try/finally statements and to check for nested statements (e.g., inside of an ``if`` statement). * Recognize classes explicitly inheriting from ``abc.ABC`` or having an ``abc.ABCMeta`` metaclass as abstract. This makes them not trigger W0223. Closes 3098 * Fix overzealous `arguments-differ` when overridden function uses variadics No message is emitted if the overriding function provides positional or keyword variadics in its signature that can feasibly accept and pass on all parameters given by the overridden function. Close 1482 Close 1553 * Multiple types of string formatting are allowed in logging functions. The `logging-fstring-interpolation` message has been brought back to allow multiple types of string formatting to be used. Close 3361 ``` ### 2.4.4 ``` =========================== Release date: 2019-11-13 * Exempt all the names found in type annotations from ``unused-import`` The previous code was assuming that only ``typing`` names need to be exempted, but we need to do that for the rest of the type comment names as well. Close 3112 * Relax type import detection for names that do not come from the ``typing`` module Close 3191 ``` ### 2.4.3 ``` =========================== Release date: 2019-10-18 * Fix an issue with ``unnecessary-comprehension`` in comprehensions with additional repacking of elements. Close 3148 * ``import-outside-toplevel`` is emitted for ``ImportFrom`` nodes as well. Close 3175 * Do not emit ``no-method-argument`` for functions using positional only args. Close 3161 * ``consider-using-sys-exit`` is no longer emitted when `exit` is imported in the local scope. Close 3147 * `invalid-overridden-method` takes `abc.abstractproperty` in account Close 3150 * Fixed ``missing-yield-type-doc`` getting incorrectly raised when a generator does not document a yield type but has a type annotation. Closes 3185 * ``typing.overload`` functions are exempted from ``too-many-function-args`` Close 3170 ```
