Scheduled weekly dependency update for week 39

[pyup-bot]

Update astroid from 2.2.5 to 2.3.1.

Changelog

2.3.1

============================
Release Date: 2019-09-30

* A transform for the builtin `dataclasses` module was added.

This should address various `dataclasses` issues that were surfaced
even more after the release of pylint 2.4.0.
In the previous versions of `astroid`, annotated assign nodes were
allowed to be retrieved via `getattr()` but that no longer happens
with the latest `astroid` release, as those attribute are not actual
attributes, but rather virtual ones, thus an operation such as `getattr()`
does not make sense for them.

* Update attr brain to partly understand annotated attributes

Close 656

2.3.0

============================
Release Date: 2019-09-24

* Add a brain tip for ``subprocess.check_output``

Close 689

* Remove NodeNG.nearest method because of lack of usage in astroid and pylint.

Close 691

* Allow importing wheel files. Close 541

* Annotated AST follows PEP8 coding style when converted to string.

* Fix a bug where defining a class using type() could cause a DuplicateBasesError.

Close 644

* Dropped support for Python 3.4.

* Numpy brain support is improved.

Numpy's fundamental type ``numpy.ndarray`` has its own brain : ``brain_numpy_ndarray`` and
each numpy module that necessitates brain action has now its own numpy brain :

 - ``numpy.core.numeric``
 - ``numpy.core.function_base``
 - ``numpy.core.multiarray``
 - ``numpy.core.numeric``
 - ``numpy.core.numerictypes``
 - ``numpy.core.umath``
 - ``numpy.random.mtrand``

* ``assert`` only functions are properly inferred as returning ``None``

Close 668

* Add support for Python 3.8's `NamedExpr` nodes, which is part of assignment expressions.

Close 674

* Added support for inferring `IfExp` nodes.

* Instances of exceptions are inferred as such when inferring in non-exception context

This allows special inference support for exception attributes such as `.args`.

Close PyCQA/pylint2333

* Drop a superfluous and wrong callcontext when inferring the result of a context manager

Close PyCQA/pylint2859

* ``igetattr`` raises ``InferenceError`` on re-inference of the same object

This prevents ``StopIteration`` from leaking when we encounter the same
object in the current context, which could result in various ``RuntimeErrors``
leaking in other parts of the inference.
Until we get a global context per inference, the solution is sort of a hack,
as with the suggested global context improvement, we could theoretically
reuse the same inference object.

Close 663

* Variable annotations can no longer be retrieved with `ClassDef.getattr`

Unless they have an attached value, class variable annotations can no longer
be retrieved with `ClassDef.getattr.`

* Improved builtin inference for ``tuple``, ``set``, ``frozenset``, ``list`` and ``dict``

We were properly inferring these callables *only* if they had consts as
values, but that is not the case most of the time. Instead we try to infer
the values that their arguments can be and use them instead of assuming
Const nodes all the time.

Close PyCQA/pylint2841

* The last except handler wins when inferring variables bound in an except handler.

Close PyCQA/pylint2777


* ``threading.Lock.locked()`` is properly recognized as a member of ``threading.Lock``

Close PyCQA/pylint2791


* Fix recursion error involving ``len`` and self referential attributes

Close PyCQA/pylint2736
Close PyCQA/pylint2734
Close PyCQA/pylint2740

* Can access per argument type comments through new ``Arguments.type_comment_args`` attribute.

Close 665

* Fix being unable to access class attributes on a NamedTuple.

Close PyCQA/pylint1628

* Fixed being unable to find distutils submodules by name when in a virtualenv.

Update pylint from 2.3.1 to 2.4.2.

Changelog

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.
