92: Pin pylint to latest version 2.4.4 r=duckinator a=pyup-bot
This PR pins [pylint](https://pypi.org/project/pylint) to the latest release **2.4.4**.
<details>
<summary>Changelog</summary>
### 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
```
### 2.4.2
```
===========================
Release date: 2019-09-30
* ``ignored-modules`` can skip submodules. Close 3135
* ``self-assigning-variable`` skips class level assignments.
Close 2930
* ``consider-using-sys-exit`` is exempted when `exit()` is imported from `sys`
Close 3145
* Exempt annotated assignments without variable from ``class-variable-slots-conflict``
Close 3141
* Fix ``utils.is_error`` to account for functions returning early.
This fixes a false negative with ``unused-variable`` which was no longer triggered
when a function raised an exception as the last instruction, but the body of the function
still had unused variables.
Close 3028
```
### 2.4.1
```
===========================
Release date: 2019-09-25
* Exempt type checking definitions defined in both clauses of a type checking guard
Close 3127
* Exempt type checking definitions inside the type check guard
In a7f236528bb3758886b97285a56f3f9ce5b13a99 we added basic support
for emitting `used-before-assignment` if a variable was only defined
inside a type checking guard (using `TYPE_CHECKING` variable from `typing`)
Unfortunately that missed the case of using those type checking imports
inside the guard itself, which triggered spurious used-before-assignment errors.
Close 3119
* Require astroid >= 2.3 to avoid any compatibility issues.
```
### 2.4.0
```
===========================
Release date: 2019-09-24
* New check: ``import-outside-toplevel``
This check warns when modules are imported from places other than a
module toplevel, e.g. inside a function or a class.
* Handle inference ambiguity for ``invalid-format-index``
Close 2752
* Removed Python 2 specific checks such as ``relative-import``,
``invalid-encoded-data``, ``missing-super-argument``.
* Support forward references for ``function-redefined`` check.
Close 2540
* Handle redefinitions in case of type checking imports.
Close 2834
* Added a new check, ``consider-using-sys-exit``
This check is emitted when we detect that a quit() or exit() is invoked
instead of sys.exit(), which is the preferred way of exiting in program.
Close 2925
* ``useless-suppression`` check now ignores ``cyclic-import`` suppressions,
which could lead to false postiives due to incomplete context at the time
of the check.
Close 3064
* Added new checks, ``no-else-break`` and ``no-else-continue``
These checks highlight unnecessary ``else`` and ``elif`` blocks after
``break`` and ``continue`` statements.
Close 2327
* Don't emit ``protected-access`` when a single underscore prefixed attribute
is used inside a special method
Close 1802
* Fix the "statement" values in the PyLinter's stats reports by module.
* Added a new check, ``invalid-overridden-method``
This check is emitted when we detect that a method is overridden
as a property or a property is overridden as a method. This can indicate
a bug in the application code that will trigger a runtime error.
Close 2670
* Added a new check, ``arguments-out-of-order``
This check warns if you have arguments with names that match those in
a function's signature but you are passing them in to the function
in a different order.
Close 2975
* Added a new check, ``redeclared-assigned-name``
This check is emitted when ``pylint`` detects that a name
was assigned one or multiple times in the same assignment,
which indicate a potential bug.
Close 2898
* Ignore lambda calls with variadic arguments without a context.
Inferring variadic positional arguments and keyword arguments
will result into empty Tuples and Dicts, which can lead in
some cases to false positives with regard to no-value-for-parameter.
In order to avoid this, until we'll have support for call context
propagation, we're ignoring such cases if detected.
We already did that for function calls, but the previous fix
was not taking in consideration ``lambdas``
Close 2918
* Added a new check, ``self-assigning-variable``
This check is emitted when we detect that a variable is assigned
to itself, which might indicate a potential bug in the code application.
Close 2930
* Added a new check, ``property-with-parameters``.
This check is emitted when we detect that a defined property also
has parameters, which are useless.
Close 3006
* Excluded protocol classes from a couple of checks. Close 3002.
* Add a check `unnecessary-comprehension` that detects unnecessary comprehensions.
This check is emitted when ``pylint`` finds list-, set- or dict-comprehensions,
that are unnecessary and can be rewritten with the list-, set- or dict-constructors.
Close 2905
* Excluded PEP 526 instance and class variables from ``no-member``. Close 2945
* Excluded `attrs` from `too-few-public-methods` check. Close 2988.
* ``unused-import`` emitted for the right import names in function scopes.
Close 2928
* Dropped support for Python 3.4.
* ``assignment-from-no-return`` not triggered for async methods.
Close 2902
* Don't emit ``attribute-defined-outside-init`` for variables defined in setters.
Close 409
* Syntax errors report the column number.
Close 2914
* Support fully qualified typing imports for type annotations.
Close 2915
* Exclude ``__dict__`` from ``attribute-defined-outside-init``
* Fix pointer on spelling check when the error are more than one time in the same line.
Close 2895
* Fix crash happening when parent of called object cannot be determined
* Allow of in `GoogleDocstring.re_multiple_type`
* Added `subprocess-run-check` to handle subrocess.run without explicitly set `check` keyword.
Close 2848
* When we can't infer bare except handlers, skip ``try-except-raise``
Close 2853
* Handle more `unnecessary-lambda` cases when dealing with additional kwargs in wrapped calls
Close 2845
* Better postponed evaluation of annotations handling
Close 2847
* Support postponed evaluation of annotations for variable annotations.
Close 2838
* ``epylint.py_run`` defaults to ``python`` in case the current executable is not a Python one.
Close 2837
* Ignore raw docstrings when running Similarities checker with `ignore-docstrings=yes` option
* Fix crash when calling ``inherit_from_std_ex`` on a class which is its own ancestor
Close 2680
* Added a new check that warns the user if a function call is used inside a test but parentheses are missing.
Close 2658
* ``len-as-condition`` now only fires when a ``len(x)`` call is made without an explicit comparison
The message and description accompanying this checker has been changed
reflect this new behavior, by explicitly asking to either rely on the
fact that empty sequence are false or to compare the length with a scalar.
Close 2684
* Add ``preferred-module`` checker that notify if an import has a replacement module that should be used.
This check is emitted when ``pylint`` finds an imported module that has a
preferred replacement listed in ``preferred-modules``.
* ``assigning-non-slot`` not emitted for classes with unknown base classes.
Close 2807
* ``old-division`` is not emitted for non-Const nodes.
Close 2808
* Added method arguments to the dot writer for pyreverse.
Close 2139
* Support for linting file from stdin.
IDEs may benefit from the support for linting from an in-memory file.
Close 1187
* Added a new check `class-variable-slots-conflict`
This check is emitted when ``pylint`` finds a class variable that conflicts with a slot
name, which would raise a ``ValueError`` at runtime.
* Added new check: dict-iter-missing-items (E1141)
Close 2761
* Fix issue with pylint name in output of python -m pylint --version
Close 2764
* Relicense logo material under the CC BY-SA 4.0 license.
* Skip `if` expressions from f-strings for the `check_elif` checker
Close 2816
* C0412 (ungrouped-import) is now compatible with isort.
Close 2806
* Added new extension to detect too much code in a try clause
Close 2877
* ``signature-mutators`` option was added
With this option, users can choose to ignore `too-many-function-args`, `unexpected-keyword-arg`,
and `no-value-for-parameter` for functions decorated with decorators that change
the signature of a decorated function.
Close 259
* Fixed a pragma comment on its own physical line being ignored when part
of a logical line with the previous physical line.
Close 199
* Fixed false `undefined-loop-variable` for a function defined in the loop,
that uses the variable defined in that loop.
Close 202
* Fixed `unused-argument` and `function-redefined` getting raised for
functions decorated with `typing.overload`.
Close 1581
* Fixed a false positive with ``consider-using-dict-comprehension`` for constructions that can't be converted to a comprehension
Close 2963
* Added ``__post_init__`` to ``defining-attr-methods`` in order to avoid ``attribute-defined-outside-init`` in dataclasses.
Close 2581
* Changed description of W0199 to use the term 2-item-tuple instead of 2-uple.
* Allow a `.` as a prefix for Sphinx name resolution.
* Checkers must now keep a 1 to 1 relationship between "msgid" (ie: C1234) and "symbol" (ie : human-readable-symbol)
* In checkers, an old_names can now be used for multiple new messages and pylint is now a little faster
Caused by 1164. It means if you do a partial old_names for a message definition an exception will tell you that you
must rename the associated identification.
* Allow the choice of f-strings as a valid way of formatting logging strings.
Closes 2395
* Added ``--list-msgs-enabled`` command to list all enabled and disabled messages given the current RC file and command line arguments.
```
### 2.3.0
```
===========================
Release date: 2019-02-27
* Protect against `NonDeducibleTypeHierarchy` when calling semi-private `is_subtype`
`astroid.helpers.is_subtype` raises `NonDeducibleTypeHierarchy` when it cannot infer
the base classes of the given types, but that makes sense in its context given that
the method is mostly used to inform the inference process about the hierarchy of classes.
Doesn't make that much sense for ``pylint`` itself, which is why we're handling the
exception here, rather than in ``astroid``
Close PyCQA/astroid644
* Added a new command line option ``list-groups`` for listing all the check groups ``pylint`` knows about.
* Allow ``BaseException`` for emitting ``broad-except``, just like ``Exception``.
Close 2741
* Fixed a crash that occurred for ``bad-str-strip-call`` when ``strip()`` received ``None``
Close 2743
* Don't emit ``*-not-iterating`` checks for builtins consumed by ``itertools``
Close 2731
* Fix a crash caused by iterating over ``Uninferable`` in a string formatting check.
Close 2727
* Fixed false positives for ``no-self-argument`` and ``unsubscriptable-object`` when using ``__class_getitem__`` (new in Python 3.7)
Close 2416
* Support ``Ellipsis`` as a synonym for ``pass`` statements.
Close 2718
* ``fixme`` gets triggered only on comments.
Close 2321
* Fixed a false positive for ``unused-variable`` and ``nonlocal`` assignments
Close 2671
* Added ``load_configuration()`` hook for plugins
New optional hook for plugins is added: ``load_configuration()``.
This hook is executed after configuration is loaded to prevent
overwriting plugin specific configuration via user-based
configuration.
Close 2635
* Fix missing-raises-doc false positive (W9006)
Close 1502
* Exempt starred unpacking from ``*-not-iterating`` Python 3 checks
Close 2651
* Make ``compare-to-zero`` less zealous by checking against equality and identity
Close 2645
* Add ``no-else-raise`` warning (R1720)
Close 2558
* Exempt ``yield from`` from ``*-not-iterating`` Python 3 checks.
Close 2643
* Fix incorrect generation of ``no-else-return`` warnings (R1705)
Fixed issue where ``if`` statements with nested ``if`` statements
were incorrectly being flagged as ``no-else-return`` in some cases and
not being flagged as ``no-else-return`` in other cases. Added tests
for verification and updated pylint source files to eliminate newly
exposed warnings.
* Fix false positive with `not-async-context-manager` caused by not understanding `contextlib.asynccontextmanager`
Close 2440
* Refactor ``bad-reversed-sequence`` to account for more objects that can define ``__reversed__``
One such object would be an enum class, for which ``__reversed__`` yields each individual enum.
As such, the check for ``bad-reversed-sequence`` needs to not differentiate between classes
and instances when it comes for checking of ``__reversed__`` presence.
Close 2598
* Added ``wrong-exception-operation``
Used when an operation is done against an exception, but the operation
is not valid for the exception in question. Usually emitted when having
binary operations between exceptions in except handlers.
Close 2494
* ``no-member`` is emitted for enums when they lack a member
Previously we weren't doing this because we detected a
``__getattr__`` implementation on the ``Enum`` class
(and this check is skipped for classes with ``__getattr__``),
but that is fine for Enums, given that they are inferred in a customised
way in astroid.
Close 2565
* Generalize ``chained-comparison``
Previous version incorrectly detects `a < b < c and b < d` and fails to
detect `a < b < c and c < d`.
* Avoid popping __main__ when using multiple jobs
Close 2689
* Add a new option 'check-str-concat-over-line-jumps' to check 'implicit-str-concat-in-sequence'
* Fixes for the new style logging format linter.
The number of arguments was not handled properly, leading to an always
successful check.
* Fix false positive ``not-callable`` for uninferable properties.
* Fix false positive ``useless-else-on-loop`` if the break is deep in the else
of an inner loop.
* Minor improvements to the help text for a few options.
```
### 2.2.2
```
===========================
Release date: 2018-11-28
* Change the ``logging-format-style`` to use name identifier instead of their
corresponding Python identifiers
This is to prevent users having to think about escaping the default value for
``logging-format-style`` in the generated config file. Also our config parsing
utilities don't quite support escaped values when it comes to ``choices`` detection,
so this would have needed various hacks around that.
Closes 2614
```
### 2.2.1
```
===========================
Release date: 2018-11-27
* Fix a crash caused by `implicit-str-concat-in-sequence` and multi-bytes characters.
Closes 2610
```
### 2.2
```
=========================
Release date: 2018-11-25
* Consider ``range()`` objects for ``undefined-loop-variable`` leaking from iteration.
Close 2533
* ``deprecated-method`` can use the attribute name for identifying a deprecated method
Previously we were using the fully qualified name, which we still do, but the fully
qualified name for some ``unittest`` deprecated aliases leads to a generic
deprecation function. Instead on relying on that, we now also rely on the attribute
name, which should solve some false positives.
Close 1653
Close 1946
* Fix compatibility with changes to stdlib tokenizer.
* ``pylint`` is less eager to consume the whole line for pragmas
Close 2485
* Obtain the correct number of CPUs for virtualized or containerized environments.
Close 2519
* Change ``unbalanced-tuple-unpacking`` back to a warning.
It used to be a warning until a couple of years ago, after it was promoted to
an error. But the check might be suggesting the wrong thing in some cases,
for instance when checking against ``sys.argv`` which cannot be known at static
analysis time. Given it might rely on potential unknown data, it's best to
have it as a warning.
Close 2522
* Remove ``enumerate`` usage suggestion when defining ``__iter__`` (C0200)
Close 2477
* Emit ``too-many-starred-assignment`` only when the number of Starred nodes is per assignment elements
Close 2513
* `try-except-raise` checker now handles multilevel inheritance hirerachy for exceptions correctly.
Close 2484
* Add a new check, ``simplifiable-if-expression`` for expressions like ``True if cond else False``.
Close 2487
* ``too-few-public-methods`` is not reported for ``typing.NamedTuple``
Close 2459
* too-few-public-methods`` is not reported for dataclasses created with options.
Close 2488
* Remove wrong modules from 'bad-python3-import'.
Close 2453
* The ``json`` reporter prints an empty list when no messages are emitted
Close 2446
* Add a new check, ``duplicate-string-formatting-argument``
This new check is emitted whenever a duplicate string formatting argument
is found.
Close 497
* ``assignment-from-no-return`` is not emitted for coroutines.
Close 1715
* Report format string type mismatches.
* ``consider-using-ternary`` and ``simplified-boolean-expression`` no longer emit for sequence based checks
Close 2473
* Handle ``AstroidSyntaxError`` when trying to import a module.
Close 2313
* Allow ``__module__`` to be redefined at a class level. Close 2451
* ``pylint`` used to emit a ``unused-variable`` error if unused import was found in the function. Now instead of
``unused-variable``, ``unused-import`` is emitted.
Close 2421
* Handle asyncio.coroutine when looking for ``not-an-iterable`` check.
Close 996
* The ``locally-enabled`` check is gone.
Close 2442
* Infer decorated methods when looking for method-hidden
Close 2369
* Pick the latest value from the inferred values when looking for ``raising-non-exception``
Close 2431
* Extend the TYPE_CHECKING guard to TYPE_CHECKING name as well, not just the attribute
Close 2411
* Ignore import x.y.z as z cases for checker `useless-import-alias`.
Close 2309
* Fix false positive ``undefined-variable`` and ``used-before-assignment`` with nonlocal keyword usage.
Close 2049
* Stop ``protected-access`` exception for missing class attributes
* Don't emit `assignment-from-no-return` for decorated function nodes
Close 2385
* `unnecessary-pass` is now also emitted when a function or class contains only docstring and pass statement.
In Python, stubbed functions often have a body that contains just a single `pass` statement,
indicating that the function doesn't do anything. However, a stubbed function can also have just a
docstring, and function with a docstring and no body also does nothing.
Close 2208
* ``duplicate-argument-name`` is emitted for more than one duplicate argument per function
Close 1712
* Allow double indentation levels for more distinguishable indentations
Close 741
* Consider tuples in exception handler for ``try-except-raise``.
Close 2389
* Fix astroid.ClassDef check in checkers.utils.is_subclass_of
* Fix wildcard imports being ignored by the import checker
* Fix external/internal distinction being broken in the import graph
* Fix wildcard import check not skipping `__init__.py`
Close 2430
* Add new option to logging checker, ``logging_format_style``
* Fix --ignore-imports to understand multi-line imports
Close 1422
Close 2019
* Add a new check 'implicit-str-concat-in-sequence' to spot string concatenation inside lists, sets & tuples.
* ``literal-comparison`` is now emitted for 0 and 1 literals.
```
### 2.1.1
```
===========================
Release date: 2018-08-07
* fix pylint crash due to ``misplaced-format-function`` not correctly handling class attribute.
Close 2384
* Do not emit \*-builtin for Python 3 builtin checks when the builtin is used inside a try-except
Close PyCQA/pylint2228
* ``simplifiable-if-statement`` not emitted when dealing with subscripts
```
### 2.1
```
=========================
Release date: 2018-08-01
* `trailing-comma-tuple` gets emitted for ``yield`` statements as well.
Close 2363
* Get only the arguments of the scope function for `redefined-argument-from-local`
Close 2364
* Add a check `misplaced-format-function` which is emitted if format function is used on
non str object.
Close 2200
* `chain.from_iterable` no longer emits `dict-{}-not-iterating` when dealing with dict values and keys
* Demote the `try-except-raise` message from an error to a warning (E0705 -> W0706)
Close 2323
* Correctly handle the new name of the Python implementation of the `abc` module.
Close PyCQA/astroid2288
* Modules with `__getattr__` are exempted by default from `no-member`
There's no easy way to figure out if a module has a particular member when
the said module uses `__getattr__`, which is a new addition to Python 3.7.
Instead we assume the safe thing to do, in the same way we do for classes,
and skip those modules from checking.
Close 2331
* Fix a false positive `invalid name` message when method or attribute name is longer then 30 characters.
Close 2047
* Include the type of the next branch in `no-else-return`
Close 2295
* Fix inconsistent behaviour for bad-continuation on first line of file
Close 2281
* Fix not being able to disable certain messages on the last line through
the global disable option
Close 2278
* Don't emit `useless-return` when we have a single statement that is the return itself
We still want to be explicit when a function is supposed to return
an optional value; even though `pass` could still work, it's not explicit
enough and the function might look like it's missing an implementation.
Close 2300
* Fix false-positive undefined-variable for self referential class name in lamdbas
Close 704
* Don't crash when `pylint` is unable to infer the value of an argument to `next()`
Close 2316
* Don't emit `not-an-iterable` when dealing with async iterators.
But do emit it when using the usual iteration protocol against
async iterators.
Close 2311
* Can specify a default docstring type for when the check cannot guess the type
Close 1169
```
### 2.0
```
=========================
Release date: 2018-07-15
* `try-except-raise` should not be emitted if there are any parent exception class handlers.
Close 2284
* `trailing-comma-tuple` can be emitted for `return` statements as well.
Close 2269
* Fix a false positive ``inconsistent-return-statements`` message when exception is raised
inside an else statement.
Close 1782
* `ImportFrom` nodes correctly use the full name for the import sorting checks.
Close 2181
* [].extend and similar builtin operations don't emit `dict-*-not-iterating` with the Python 3 porting checker
Close 2187
* Add a check `consider-using-dict-comprehension` which is emitted if for dict initialization
the old style with list comprehensions is used.
* Add a check `consider-using-set-comprehension` which is emitted if for set initialization
the old style with list comprehensions is used.
* `logging-not-lazy` is emitted whenever pylint infers that a string is built with addition
Close 2193
* Add a check `chained-comparison` which is emitted if a boolean operation can be simplified
by chaining some of its operations.
e.g "a < b and b < c", can be simplified as "a < b < c".
Close 2032
* Add a check `consider-using-in` for comparisons of a variable against
multiple values with "==" and "or"s instead of checking if the variable
is contained "in" a tuple of those values.
* `in` is considered iterating context for some of the Python 3 porting checkers
Close 2186
* Add `--ignore-none` flag to control if pylint should warn about `no-member` where the owner is None
* Fix a false positive related to `too-many-arguments` and bounded `__get__` methods
Close 2172
* `mcs` as the first parameter of metaclass's `__new__` method was replaced by `cls`
Close 2028
* `assignment-from-no-return` considers methods as well.
Close 2081
* Support typing.TYPE_CHECKING for *unused-import* errors
Close 1948
* Inferred classes at a function level no longer emit `invalid-name`
when they don't respect the variable regular expression
Close 1049
* Added basic support for postponed evaluation of function annotations.
Close 2069
* Fix a bug with `missing-kwoa` and variadics parameters
Close 1111
* `simplifiable-if-statement` takes in account only when assigning to same targets
Close 1984
* Make ``len-as-condition`` test more cases, such as ``len() < 1`` or ``len <= 0``
* Fix false-positive ``line-too-long`` message emission for
commented line at the end of a module
Close 1950
* Fix false-positive ``bad-continuation`` for with statements
Close 461
* Don't warn about `stop-iteration-return` when using `next()` over `itertools.count`
Close 2158
* Add a check `consider-using-get` for unidiomatic usage of value/default-retrieval
for a key from a dictionary
Close 2076
* invalid-slice-index is not emitted when the slice is used as index for a complex object.
We only use a handful of known objects (list, set and friends) to figure out if
we should emit invalid-slice-index when the slice is used to subscript an object.
* Don't emit `unused-import` anymore for typing imports used in type comments.
* Add a new check 'useless-import-alias'.
Close 2052
* Add `comparison-with-callable` to warn for comparison with bare callable, without calling it.
Close 2082
* Don't warn for ``missing-type-doc`` and/or ``missing-return-type-doc``, if type
annotations exist on the function signature for a parameter and/or return type.
Close 2083
* Add `--exit-zero` option for continuous integration scripts to more
easily call Pylint in environments that abort when a program returns a
non-zero (error) status code.
Close 2042
* Warn if the first argument of an instance/ class method gets assigned
Close 977
* New check `comparison-with-itself` to check comparison between same value.
Close 2051

is used within logging function calls.
Close 1998
* Don't show 'useless-super-delegation' if the subclass method has different type annotations.
Close 1923
* Add `unhashable-dict-key` check.
Closes 586
* Don't warn that a global variable is unused if it is defined by an import

Close 2026
* The Python 3 porting mode can now run with Python 3 as well.
* `too-few-public-methods` is not emitted for dataclasses.
Close 1793
* New verbose mode option, enabled with `--verbose` command line flag, to
display of extra non-checker-related output. It is disabled by default.
Close 1863
* `undefined-loop-variable` takes in consideration non-empty iterred objects before emitting
Close 2039
* Add support for numpydoc optional return value names.
Close 2030
* `singleton-comparison` accounts for negative checks
Close 2037
* Add a check `consider-using-in` for comparisons of a variable against
multiple values with "==" and "or"s instead of checking if the variable
is contained "in" a tuple of those values.
Close 1977
* defaultdict and subclasses of dict are now handled for dict-iter-* checks
Close 2005
* `logging-format-interpolation` also emits when f-strings are used instead of % syntax.
Close 1788
* Don't trigger misplaced-bare-raise when the raise is in a finally clause
Close 1924
* Add a new check, `possibly-unused-variable`.
This is similar to `unused-variable`, the only difference is that it is
emitted when we detect a locals() call in the scope of the unused variable.
The `locals()` call could potentially use the said variable, by consuming
all values that are present up to the point of the call. This new check
allows to disable this error when the user intentionally uses `locals()`
to consume everything.
Close 1909.
* `no-else-return` accounts for multiple cases
The check was a bit overrestrictive because we were checking for
return nodes in the .orelse node. At that point though the if statement
can be refactored to not have the orelse. This improves the detection of
other cases, for instance it now detects TryExcept nodes that are part of
the .else branch.
Close 1852
* Added two new checks, `invalid-envvar-value` and `invalid-envvar-default`.
The former is trigger whenever pylint detects that environment variable manipulation
functions uses a different type than strings, while the latter is emitted whenever
the said functions are using a default variable of different type than expected.
* Add a check `consider-using-join` for concatenation of strings using str.join(sequence)
Close 1952
* Add a check `consider-swap-variables` for swapping variables with tuple unpacking
Close 1922
* Add new checker `try-except-raise` that warns the user if an except handler block
has a ``raise`` statement as its first operator. The warning is shown when there is
a bare raise statement, effectively re-raising the exception that was caught or the
type of the exception being raised is the same as the one being handled.
* Don't crash on invalid strings when checking for `logging-format-interpolation`
Close 1944
* Exempt `__doc__` from triggering a `redefined-builtin`
`__doc__` can be used to specify a docstring for a module without
passing it as a first-statement string.

default value in a generator
Close 1830
* Fix emission of false positive ``no-member`` message for class with "private" attributes whose name is mangled.

### 1.9
```
=========================
Release date: 2018-05-15
* Added two new Python 3 porting checks, `exception-escape` and `comprehension-escape`
These two are emitted whenever pylint detects that a variable defined in the
said blocks is used outside of the given block. On Python 3 these values are deleted.
* Added a new `deprecated-sys-function`, emitted when accessing removed sys members.
* Added `xreadlines-attribute`, emitted when the `xreadlines()` attribute is accessed.
* The Python 3 porting mode can now run with Python 3 as well.
* docparams extension allows abstract methods to document what overriding
implementations should return, and to raise NotImplementedError without
documenting it.
Closes 2044
* Special methods do not count towards `too-few-methods`,
and are considered part of the public API.
* Enum classes do not trigger `too-few-methods`
Close 605
* Added a new Python 2/3 check for accessing `operator.div`, which is removed in Python 3
Close 1936
* Added a new Python 2/3 check for accessing removed urllib functions

```
### 1.8.1
```
===========================
Release date: 2017-12-15
* Wrong version number in __pkginfo__.
```
### 1.8
```
=========================
Release date: 2017-12-15
* Respect disable=... in config file when running with --py3k.
* New warning `shallow-copy-environ` added
Shallow copy of os.environ doesn't work as people may expect. os.environ
is not a dict object but rather a proxy object, so any changes made
on copy may have unexpected effects on os.environ
Instead of copy.copy(os.environ) method os.environ.copy() should be
used.
See https://bugs.python.org/issue15373 for details.
Close 1301

* Fixing u'' string in superfluous-parens message
Close 1420
* `abstract-class-instantiated` is now emitted for all inference paths.
Close 1673
* Add set of predefined naming style to ease configuration of checking
naming conventions.
Closes 1013
* Added a new check, ``keyword-arg-before-vararg``
This is emitted for function definitions
in which keyword arguments are placed before variable
positional arguments (\*args).
This may lead to args list getting modified if keyword argument's value
is not provided in the function call assuming it will take default value
provided in the definition.
* The `invalid-name` check contains the name of the template that caused the failure
Close 1176
* Using the -j flag won't start more child linters than needed.

* Fix a false positive with bad-python3-import on relative imports
Close 1608
* Added a new Python 3 check, ``non-ascii-bytes-literals``
Close 1545
* Added a couple of new Python 3 checks for accessing dict methods in non-iterable context
* Protocol checks (not-a-mapping, not-an-iterable and co.) aren't emitted on classes with dynamic getattr
* Added a new warning, 'bad-thread-instantiation'
This message is emitted when the threading.Thread class does not
receive the target argument, but receives just one argument, which
is by default the group parameter.
Close 1327
* In non-quiet mode, absolute path of used config file is logged to
standard error.
Close 1519
* Raise meaningful exception for invalid reporter class being selected
When unknown reporter class will be selected as Pylint reporter,
meaningful error message would be raised instead of bare ``ImportError``
or ``AttribueError`` related to module or reporter class being not found.
Close 1388
* Added a new Python 3 check for accessing removed functions from itertools
like ``izip`` or ``ifilterfalse``
* Added a new Python 3 check for accessing removed fields from the types
module like ``UnicodeType`` or ``XRangeType``
* Added a new Python 3 check for declaring a method ``next`` that would have
been treated as an iterator in Python 2 but a normal function in Python 3.
* Added a new key-value pair in json output. The key is ``message-id``
and the value is the message id.
Close 1512
* Added a new Python 3.0 check for raising a StopIteration inside a generator.
The check about raising a StopIteration inside a generator is also valid if the exception
raised inherit from StopIteration.
Close 1385
* Added a new warning, ``raising-format-tuple``, to detect multi-argument
exception construction instead of message string formatting.
* Added a new check for method of logging module that concatenate string via + operator
Close 1479
* Added parameter for limiting number of suggestions in spellchecking checkers
* Fix a corner-case in ``consider-using-ternary`` checker.
When object ``A`` used in ``X and A or B`` was falsy in boolean context,
Pylint incorrectly emitted non-equivalent ternary-based suggestion.
After a change message is correctly not emitted for this case.
Close 1559
* Added ``suggestion-mode`` configuration flag. When flag is enabled, informational
message is emitted instead of cryptic error message for attributes accessed on
c-extensions.
Close 1466
* Fix a false positive ``useless-super-delegation`` message when
parameters default values are different from those used in the base class.
Close 1085
* Disabling 'wrong-import-order', 'wrong-import-position', or
'ungrouped-imports' for a single line now prevents that line from
triggering violations on subsequent lines.
Close 1336
* Added a new Python check for inconsistent return statements inside method or function.
Close 1267
* Fix ``superfluous-parens`` false positive related to handling logical statements
involving ``in`` operator.
Close 574
* ``function-redefined`` message is no longer emitted for functions and
methods which names matches dummy variable name regular expression.
Close 1369
* Fix ``missing-param-doc`` and ``missing-type-doc`` false positives when
mixing ``Args`` and ``Keyword Args`` in Google docstring.
Close 1409
* Fix ``missing-docstring`` false negatives when modules, classes, or methods
consist of compound statements that exceed the ``docstring-min-length``
* Fix ``useless-else-on-loop`` false positives when break statements are
deeply nested inside loop.
Close 1661
* Fix no ``wrong-import-order`` message emitted on ordering of first and third party
libraries. With this fix, pylint distinguishes third and first party
modules when checking import order.
Close 1702
* Fix ``pylint disable=fixme`` directives ignored for comments following the
last statement in a file.
Close 1681
* Fix ``line-too-long`` message deactivated by wrong disable directive.
The directive ``disable=fixme`` doesn't deactivate anymore the emission
of ``line-too-long`` message for long commented lines.
Close 1741
* If the rcfile specified on the command line doesn't exist, then an
IOError exception is raised.
Close 1747
* Fix the wrong scope of the ``disable=`` directive after a commented line.
For example when a ``disable=line-too-long`` directive is at the end of
a long commented line, it no longer disables the emission of ``line-too-long``
message for lines that follow.
Close 1742

### 1.7.1
```
===========================
Release date: 2017-04-17
* Fix a false positive which occurred when an exception was reraised
Close 1419
* Fix a false positive of ``disallow-trailing-tuple``
The check was improved by verifying for non-terminating newlines, which
should exempt function calls and function definitions from the check
Close 1424
```
### 1.7
```
=========================
Release date: 2017-04-13
* Don't emit missing-final-newline or trailing-whitespace for formfeeds (page breaks).
Close 1218 and 1219
* Don't emit by default no-member if we have opaque inference objects in the inference results
This is controlled through the new flag ignore-on-opaque-inference, which is by
default True. The inference can return multiple potential results while
evaluating a Python object, but some branches might not be evaluated, which
results in partial inference. In that case, it might be useful to still emit
no-member and other checks for the rest of the inferred objects.
* Added new message `assign-to-new-keyword` to warn about assigning to names which
will become a keyword in future Python releases.
Close 1351
* Split the 'missing or differing' in parameter documentation in different error.
'differing-param-doc' covers the differing part of the old 'missing-param-doc',
and 'differing-type-doc' covers the differing part of the old 'missing-type-doc'
Close 1342
* Added a new error, 'used-prior-global-declaration', which is emitted when a name
is used prior a global declaration in a function. This causes a SyntaxError in
Python 3.6
Close 1257
* The protocol checks are emitting their messages when a special method is set to None.
Close 1263
* Properly detect if imported name is assigned to same name in different
scope.
Close 636, 848, 851, and 900
* Require one space for annotations with type hints, as per PEP 8.
* 'trailing-comma-tuple' check was added
This message is emitted when pylint finds an one-element tuple,
created by a stray comma. This can suggest a potential problem in the
code and it is recommended to use parantheses in order to emphasise the
creation of a tuple, rather than relying on the comma itself.
* Don't emit not-callable for instances with unknown bases.
Close 1213
* Treat keyword only arguments the same as positional arguments with regard to unused-argument check
* Don't try to access variables defined in a separate scope when checking for ``protected-access``
* Added new check to detect incorrect usage of len(SEQUENCE) inside
test conditions.
* Added new extension to detect comparisons against empty string constants
* Added new extension to detect comparisons of integers against zero
* Added new error conditions for 'bad-super-call'
Now detects ``super(type(self), self)`` and ``super(self.__class__, self)``
which can lead to recursion loop in derived classes.
* PyLinter.should_analyze_file has a new optional parameter, called `is_argument`
Close 1079
* Add attribute hints for missing members
Closes 1035
* Add a new warning, 'redefined-argument-from-local'
Closes 649
* Support inline comments for comma separated values in the config file
Closes 1024
* epylint.py_run's *script* parameter was removed.
* epylint.py_run now uses ``shell=False`` for running the underlying process.
Closes 441
* Added a new warning, 'useless-super-delegation'
Close 839.
* Added a new error, 'invalid-metaclass', raised when
we can detect that a class is using an improper metaclass.
Close 579
* Added a new refactoring message, 'literal-comparison'.
Close 786
* arguments-differ takes in consideration kwonlyargs and variadics
Close 983
* Removed --optimized-ast. Part of 975.
* Removed --files-output option. Part of 975.
* Removed pylint-gui from the package.
* Removed the HTML reporter. Part of 975.
* ignored-argument-names is now used for ignoring arguments for unused-variable check.
This option was used for ignoring arguments when computing the correct number of arguments
a function should have, but for handling the arguments with regard
to unused-variable check, dummy-variables-rgx was used instead. Now, ignored-argument-names
is used for its original purpose and also for ignoring the matched arguments for
the unused-variable check. This offers a better control of what should be ignored
and how.
Also, the same option was moved from the design checker to the variables checker,
which means that the option now appears under the ``[VARIABLES]`` section inside
the configuration file.
Close 862.
* Fix a false positive for keyword variadics with regard to keyword only arguments.
If a keyword only argument was necessary for a function, but that function was called
with keyword variadics (\**kwargs), then we were emitting a missing-kwoa false positive,
which is now fixed.
Close 934.
* Fix some false positives with unknown sized variadics.
Close 878
* Added a new extension, check_docstring, for checking PEP 257 conventions.
Closes 868.
* config files with BOM markers can now be read.
Close 864.
* epylint.py_run does not crash on big files, using .communicate() instead of .wait()
Close 599
* Disable reports by default and show the evaluation score by default
As per discussion from issue 746, the reports were disabled by
default in order to simplify the interaction between the tool
and the users. The score is still shown by default, as a way of
closely measuring when it increases or decreases due to changes
brought to the code.
* Disable the information category messages by default.
This is a step towards making pylint more sane, as
per the discussion from issue 746.
* Catch more cases as not proper iterables for __slots__ with
regard to invalid-slots pattern. Closes issue 775.
* empty indent strings are rejected.
* Added a new error, 'relative-beyond-top-level', which is emitted
when a relative import was attempted beyond the top level package.
Closes issue 588.
* Added a new warning, 'unsupported-assignment-operation', which is
emitted when item assignment is tried on an object which doesn't
have this ability. Closes issue 591.
* Added a new warning, 'unsupported-delete-operation', which is
emitted when item deletion is tried on an object which doesn't
have this ability. Closes issue 592.
* Fix a false positive of 'redundant-returns-doc', occurred when the documented
function was using *yield* instead of *return*.
Closes issue 984.
* Fix false positives of 'missing-[raises|params|type]-doc' due to not
recognizing keyword synonyms supported by Sphinx.
* Added a new refactoring message, 'consider-merging-isinstance', which is
emitted whenever we can detect that consecutive isinstance calls can be
merged together.
Closes issue 968
* Fix a false positive of 'missing-param-doc' and 'missing-type-doc',
occurred when a class docstring uses the 'For the parameters, see'
magic string but the class __init__ docstring does not, or vice versa.
* `redefined-outer-name` is now also emitted when a nested loop's target
variable is the same as a target variable in an outer loop.
Closes issue 911.
* Added proper exception type inference for 'missing-raises-doc'.
* Added InvalidMessageError exception class to replace asserts in
pylint.utils.
* More thorough validation in MessagesStore.register_messages() to avoid
one message accidentally overwriting another.
* InvalidMessageError, UnknownMessage, and EmptyReport exceptions are
moved to the new pylint.exceptions submodule.
* UnknownMessage and EmptyReport are renamed to UnknownMessageError and
EmptyReportError.
* Warnings 'missing-returns-type-doc' and 'missing-yields-type-doc'
have each been split into two warnings - 'missing-[return|yield]-doc'
and 'missing-[return|yield]-type-doc'.
* Added epytext support to docparams extension.
Closes 1029.
* Support having plugins with the same name and with options defined
Closes 1018
* Sort configuration options in a section
Closes 1087
* Added a new Python 3 warning around implementing '__div__', '__idiv__', or
'__rdiv__' as those methods are phased out in Python 3.
* Added a new warning, 'overlapping-except', which is
emitted when two exceptions in the same except-clause are aliases
for each other or one exceptions is an ancestor of another.
* Avoid crashing on ill-formatted strings when checking for string formatting errors.
* Added a new Python 3 warning for calling 'str.encode' or 'str.decode' with a non-text
encoding.
* Added new coding convention message, 'single-string-used-for-slots'.
Closes 1166
* Added a new Python 3 check for accessing 'sys.maxint' which was removed in Python 3 in favor
of 'sys.maxsize'
* Added a new Python 3 check for bad imports.
* Added a new Python 3 check for accessing deprecated string functions.
* Do not warn about unused arguments or function being redefined in singledispatch
registered implementations.
Closes 1032 and 1034
* Added refactoring message 'no-else-return'.
* Improve unused-variable checker to warn about unused variables in module scope.
Closes 919
* Ignore modules import as _ when checking for unused imports.
Closes 1190
* Improve handing of Python 3 classes with metaclasses declared in nested scopes.
Closes 1177
* Added refactoring message 'consider-using-ternary'.
Closes 1204
* Bug-fix for false-positive logging-format-interpolation` when format specifications
are used in formatted string.
Fixes 572
* Added a new switch ``single-line-class-stmt`` to allow single-line declaration
of empty class bodies.
Closes 738
* Protected access in form `type(self)._attribute` are now allowed.
Fixes 1031
* Let the user modify msg-template when Pylint is called from a Python script
Fixes 1269
* Imports checker supports new switch ``allow-wildcard-with-all`` which disables
warning on wildcard import when imported module defines `__all__` variable.
Fixes 831
* `too-many-format-args` and `too-few-format-args` are emitted correctly when
starred expression are used in RHS tuple.
Fixes 957
* `cyclic-import` checker supports local disable clauses. When one
of cycle imports was done in scope where disable clause was active,
cycle is not reported as violation.
Fixes 59

===========================
Release date: 2016-07-07
* Use environment markers for supporting conditional dependencies.
```
### 1.6.0
```
===========================
Release date: 2016-07-03
* Added a new extension, `pylint.extensions.mccabe`, for warning
about complexity in code.
* Deprecate support for --optimize-ast. Part of 975.
* Deprecate support for the HTML output. Part of 975.
* Deprecate support for --output-files. Part of 975.
* Fixed a documentation error for the check_docs extension. Fixes 735.
* Made the list of property-defining decorators configurable.
* Fix a bug where the top name of a qualified import was detected as unused variable.
Close 923.
* bad-builtin is now an extension check.
* generated-members support qualified name through regular expressions.
For instance, one can specify a regular expression as --generated-members=astroid.node_classes.*
for ignoring every no-member error that is accessed as in `astroid.node_classes.missing.object`.
* Add the ability to ignore files based on regex matching, with the new ``--ignore-patterns``
option.
This addresses issue 156 by allowing for multiple ignore patterns
to be specified. Rather than clobber the existing ignore option, we
introduced a new one called ignore-patterns.
* Added a new error, 'trailing-newlines', which is emitted when a file
has trailing new lines.
Closes issue 682.
* Add a new option, 'redefining-builtins-modules', for controlling the modules
which can redefine builtins, such as six.moves and future.builtins.
Close 464.
* 'reimported' is emitted when the same name is imported from different module.
Close 162.
* Add a new recommendation checker, 'consider-iterating-dictionary', which is emitted
which is emitted when a dictionary is iterated through .keys().
Close 699
* Use the configparser backport for Python 2
This fixes a problem we were having with comments inside values, which is fixed
in Python 3's configparser.
Close 828
* A new error was added, 'invalid-length-returned', when the `__len__`
special method returned something else than a non-negative number.
Close issue 557
* Switch to using isort internally for wrong-import-order.
Closes 879.
* check_docs extension can find constructor parameters in __init__.
Closes 887.
* Don't warn about invalid-sequence-index if the indexed object has unknown base
classes.
Closes 867
* Don't crash when checking, for super-init-not-called, a method defined in an if block.
* Do not emit import-error or no-name-in-module for fallback import blocks by default.
Until now, we warned with these errors when a fallback import block (a TryExcept block
that contained imports for Python 2 and 3) was found, but this gets cumbersome when
trying to write compatible code. As such, we don't check these blocks by default,
but the analysis can be enforced by using the new ``--analyse-fallback-block`` flag.
Close 769.
```
### 1.5.5
```
===========================
Release date: 2016-03-21
* Let visit_importfrom from Python 3 porting checker be called when everything is disabled
Because the visit method was filtering the patterns it was expecting to be activated,
it didn't run when everything but one pattern was disabled, leading to spurious false
positives
Close 852
* Don't emit unsubscriptable-value for classes with unknown
base classes.
Close 776.
* Use an OrderedDict for storing the configuration elements
This fixes an issue related to impredictible order of the disable / enable
elements from a config file. In certain cases, the disable was coming before
the enable which resulted in classes of errors to be enabled, even though the intention
was to disable them. The best example for this was in the context of running multiple
processes, each one of it having different enables / disables that affected the output.
Close 815
* Don't consider bare and broad except handlers as ignoring NameError,
AttributeError and similar exceptions, in the context of checkers for
these issues.
Closes issue 826
```
### 1.5.4
```
===========================
Release date: 2016-01-15
* Merge StringMethodChecker with StringFormatChecker. This fixes a
bug where disabling all the messages and enabling only a handful of
messages from the StringFormatChecker would have resulted in no
messages at all.
* Don't apply unneeded-not over sets.
```
### 1.5.3
```
===========================
Release date: 2016-01-11
* Handle the import fallback idiom with regard to wrong-import-order.
Closes issue 750.
* Decouple the displaying of reports from the displaying of messages
Some reporters are aggregating the messages instead of displaying
them when they are available. The actual displaying was conflatted
in the generate_reports. Unfortunately this behaviour was flaky
and in the case of the JSON reporter, the messages weren't shown
at all if a file had syntax errors or if it was missing.
In order to fix this, the aggregated messages can now be
displayed with Reporter.display_message, while the reports are
displayed with display_reports.
Closes issues 766 and 765.
* Ignore function calls with variadic arguments without a context.
Inferring variadic positional arguments and keyword arguments
will result into empty Tuples and Dicts, which can lead in
some cases to false positives with regard to no-value-for-parameter.
In order to avoid this, until we'll have support for call context
propagation, we're ignoring such cases if detected.
Closes issue 722.
* Treat AsyncFunctionDef just like FunctionDef nodes,
by implementing visit_asyncfunctiondef in terms of
visit_functiondef.
Closes issue 767.
* Take in account kwonlyargs when verifying that arguments
are defined with the check_docs extension.
Closes issue 745.
* Suppress reporting 'unneeded-not' inside `__ne__` methods
Closes issue 749.
```
### 1.5.2
```
===========================
Release date: 2015-12-21
* Don't crash if graphviz is not installed, instead emit a
warning letting the user to know.
Closes issue 168.
* Accept only functions and methods for the deprecated-method checker.
This prevents a crash which can occur when an object doesn't have
.qname() method after the inference.
* Don't emit super-on-old-class on classes with unknown bases.
Closes issue 721.
* Allow statements in `if` or `try` blocks containing imports.
Closes issue 714.
```
### 1.5.1
```
===========================
Release date: 2015-12-02
* Fix a crash which occurred when old visit methods are encountered
in plugin modules. Closes issue 711.
* Add wrong-import-position to check_messages's decorator arguments
for ImportChecker.leave_module
This fixes an esoteric bug which occurs when ungrouped-imports and
wrong-import-order are disabled and pylint is executed on multiple files.
What happens is that without wrong-import-position in check_messages,
leave_module will never be called, which means that the first non-import node
from other files might leak into the current file,
leading to wrong-import-position being emitted by pylint.
* Fix a crash which occurred when old visit methods are encountered
in plugin modules. Closes issue 711.
* Don't emit import-self and cyclic-import for relative imports
of modules with the same name as the package itself.
Closes issues 708 and 706.
```
### 1.5.0
```
===========================
Release date: 2015-11-29
* Added multiple warnings related to imports. 'wrong-import-order'
is emitted when PEP 8 recommendations regarding imports are not
respected (that is, standard imports should be followed by third-party
imports and then by local imports). 'ungrouped-imports' is emitted
when imports from the same package or module are not placed
together, but scattered around in the code. 'wrong-import-position'
is emitted when code is mixed with imports, being recommended for the
latter to be at the top of the file, in orde…
