python-pylint-3.3.7-160000.2.2

- Update to 3.3.7
  * Comparisons between two calls to `type()` won't raise an
    ``unidiomatic-typecheck`` warning anymore, consistent with
    the behavior applied only for ``==`` previously.
  * Fixed a crash when importing a class decorator that did not
    exist with the same name as a class attribute after the class
    definition.
  * Fix a crash caused by malformed format strings when using
    `.format` with keyword arguments.
  * Using a slice as a class decorator now raises a ``not-callable``
    message instead of crashing. A lot of checks that dealt with
    decorators (too many to list) are now shortcut if the decorator
    can't immediately be inferred to a function or class definition.
  * The algorithm used for ``no-member`` suggestions is now more
    efficient and cuts the calculation when the distance score is
    already above the threshold.

- Update to 3.3.6:
  * Fix a false positive for used-before-assignment when an inner function's
    return type * annotation is a class defined at module scope.
  * Fix false positives for use-implicit-booleaness-not-comparison,
    use-implicit-booleaness-not-comparison-to-string and
    use-implicit-booleaness-not-comparison-to-zero when chained comparisons
    are checked.
  * Fix a false positive for invalid-getnewargs-ex-returned when the tuple or
    dict has been assigned to a name.
  * Remove getopt and optparse from the list of deprecated modules.
  * Fixed conditional import x.y causing false positive
    possibly-used-before-assignment.
  * Fix a crash when something besides a class is found in an except handler.
  * Fixed raising invalid-name when using camelCase for private methods with
    two leading underscores.
  * Fixes "skipped files" count calculation; the previous method was
    displaying an arbitrary number.
  * Fixes a crash that occurred when pylint was run in a container on a host
    with cgroupsv2 and restrictions on CPU usage.
  * Relaxed the requirements for isort so pylint can benefit from isort 6.
  * Fix false positives for undefined-variable for classes using Python 3.12
    generic type syntax.
  * Fix a false positive for use-implicit-booleaness-not-len. No lint should
    be emitted for generators (len is not defined for generators).
  * Fix Unable to import 'collections.abc' (import-error) on Python 3.13.1.
  * Fix a false positive for potential-index-error when an indexed iterable
    contains a starred element that evaluates to more than one item.
  * Fixes the issue with --source-root option not working when the source
    files are in a subdirectory of the source root (e.g. when using a /src
    layout).

- Revert restriction to python3.

- Fix build error under Leap.

- update to 3.3.1:
  * Fix regression causing some f-strings to not be inferred as
    strings.
- update to 3.3.0:
  * We migrated ``symilar`` to argparse, from getopt, so the
    error and help output changed (for the better).
    We exit with 2 instead of sometime 1, sometime 2.
    The error output is not captured by the runner anymore.
    It's not possible to use a value for the boolean options
    anymore (``--ignore-comments 1`` should become
    ``--ignore-comments``).
  * Add new `declare-non-slot` error which reports when a class
    has a `__slots__` member and a type hint on the class is not
    present in `__slots__`.
  * Added `too-many-positional-arguments` to allow distinguishing
    the configuration for too many total arguments
    (with keyword-only params specified after `*`) from the
    configuration for too many positional-or-keyword or
    positional-only arguments.
  * Add `using-exception-group-in-unsupported-version` and
    `using-generic-type-syntax-in-unsupported-version` for uses
    of Python 3.11+ or 3.12+ features on lower supported versions
    provided with `--py-version`.
  * Add `using-assignment-expression-in-unsupported-version` for
    uses of `:=` (walrus operator) on Python versions below 3.8
    provided with `--py-version`.
  * Add `using-positional-only-args-in-unsupported-version` for
    uses of positional-only args on Python versions below 3.8
    provided with `--py-version`.
  * Add ``unnecessary-default-type-args`` to the ``typing``
    extension to detect the use of unnecessary default type args
    for ``typing.Generator`` and ``typing.AsyncGenerator``.
  * Fix computation of never-returning function: `Never` is
    handled in addition to `NoReturn`, and priority is given to
    the explicit `--never-returning-functions` option.
  * Fix a false negative for `await-outside-async` when await is
    inside Lambda.
  * Fix a false negative for ``duplicate-argument-name`` by
    including ``positional-only``, ``*args`` and ``**kwargs``
    arguments in the check.
  * Fix false negative for `multiple-statements` when multiple
    statements are present on `else` and `finally` lines of
    `try`.
  * Fix false negatives when `isinstance` does not have exactly
    two arguments.
  * pylint now emits a `too-many-function-args` or `no-value-for-
    parameter` appropriately for `isinstance` calls.
  * `--enable` with `--disable=all` now produces an error, when
    an unknown msg code is used. Internal `pylint` messages are
    no longer affected by `--disable=all`.
  * Impossible to compile regexes for paths in the configuration
    or argument given to pylint won't crash anymore but raise an
    argparse error and display the error message from
    ``re.compile`` instead.
  * Fix a bug where a ``tox.ini`` file with pylint configuration
    was ignored and it exists in the current directory.
  * ``.cfg`` and ``.ini`` files containing a ``Pylint``
    configuration may now use a section named ``[pylint]``. This
    enhancement impacts the scenario where these file types are
    used as defaults when they are present and have not been
    explicitly referred to, using the ``--rcfile`` option.
  * Improve file discovery for directories that are not python
    packages.
  * Remove support for launching pylint with Python 3.8.
  * Code that supports Python 3.8 can still be linted with the
    ``--py-version=3.8`` setting.
  * Add support for Python 3.13.
  * All variables, classes, functions and file names containing
    the word 'similar', when it was, in fact, referring to
    'symilar' (the standalone program for the duplicate-code
    check) were renamed to 'symilar'.
  * Remove old-style classes (Python 2) code and remove check for
    new-style class since everything is new-style in Python 3.
    Updated doc for exception checker to remove reference to new
    style class.
- update to 3.2.7:
  * Fixed a false positive `unreachable` for `NoReturn` coroutine
    functions.
  * Fix crash in refactoring checker when calling a lambda bound
    as a method.
  * Fix a crash in ``undefined-loop-variable`` when providing the
    ``iterable`` argument to ``enumerate()``.
  * Fix to address indeterminacy of error message in case a
    module name is same as another in a separate namespace.
- drop support-astroid-3.3.patch pytest-8.patch: upstream

- Update to 3.2.6:
  * Quiet false positives for unexpected-keyword-arg when pylint cannot
    determine which of two or more dynamically defined classes is being
    instantiated.
  * Fix a false positive for missing-param-doc where a method which is
    decorated with typing.overload was expected to have a docstring
    specifying its parameters.
  * Fix a regression that raised invalid-name on class attributes merely
    overriding invalid names from an ancestor.
  * Treat assert_never() the same way when imported from typing_extensions.
  * Fix a false positive for consider-using-min-max-builtin when the
    assignment target is an attribute.
  * Fix an AssertionError arising from properties that return partial
    functions.
  * Fix a crash when a subclass extends __slots__.
- Refresh pytest-8.patch.
- Add patch support-astroid-3.3.patch:
  * Support astroid >= 3.3.0.

- Add new patch to fix failing tests with pytest 8, pytest-8.patch
  gh#pylint-dev/pylint#9576
- Skip some tests that still are failing with pytest 8,
  gh#pylint-dev/pylint#9545

- update to 3.2.5:
  * Fixed a false positive ``unreachable-code`` when using
    ``typing.Any`` as return type in python 3.8, the
    ``typing.NoReturn`` are not taken into account
    anymore for python 3.8 however.
  * Prevent emitting ``possibly-used-before-assignment`` when
    relying on names only potentially not defined in conditional
    blocks guarded by functions annotated with ``typing.Never``
    or ``typing.NoReturn``.
- update to 3.2.3:
  * Classes with only an Ellipsis (``...``) in their body do not
    trigger 'multiple-statements' anymore if they are inlined
  * Fix a false positive for ``redefined-outer-name`` when there
    is a name defined in an exception-handling block which shares
    the same name as a local variable that has been defined in a
    function body.
  * Fix a false positive for ``use-yield-from`` when using the
    return value from the ``yield`` atom.
- update to 3.2.2:
  * Fix multiple false positives for generic class syntax added
    in Python 3.12 (PEP 695).
  * Exclude context manager without cleanup from
    ``contextmanager-generator-missing-cleanup`` checks.
- update to 3.2.1:
  * Exclude if/else branches containing terminating functions
    (e.g. `sys.exit()`) from `possibly-used-before-assignment`
    checks.
  * Don't emit ``typevar-name-incorrect-variance`` warnings for
    PEP 695 style TypeVars.
  * The variance is inferred automatically by the type checker.
  * Adding ``_co`` or ``_contra`` suffix can help to reason about
    TypeVar.
- update to 3.2.0:
  * Understand `six.PY2` and `six.PY3` for conditional imports.
  * Github can use to automatically annotate code. Use it with
    `pylint --output-format=github` on your Github Workflows.
  * Add check ``possibly-used-before-assignment`` when relying on
    names after an ``if/else`` switch when one branch failed to
    define the name, raise, or return.
  * Checks for generators that use contextmanagers that don't
    handle cleanup properly.
  * Is meant to raise visibilty on the case that a generator is
    not fully exhausted and the contextmanager is not cleaned up
    properly.
  * A contextmanager must yield a non-constant value and not
    handle cleanup for GeneratorExit.
  * The using generator must attempt to use the yielded context
    value `with x() as y` and not just `with x()`.

- update to 3.1.0:
  * Two new checks--``use-yield-from``, ``deprecated-
    attribute``-- and a smattering of bug fixes.
  * Skip ``consider-using-join`` check for non-empty separators
    if an ``suggest-join-with-non-empty-separator`` option is set
    to ``no``.
  * Discover ``.pyi`` files when linting.
  * Check ``TypeAlias`` and ``TypeVar`` (PEP 695) nodes for
    ``invalid-name``.
  * Support for resolving external toml files named pylintrc.toml
    and .pylintrc.toml.
  * Check for `.clear`, `.discard`, `.pop` and `remove` methods
    being called on a set while it is being iterated over.
  * New message `use-yield-from` added to the refactoring
    checker. This message is emitted when yielding from a loop
    can be replaced by `yield from`.
  * Added a ``deprecated-attribute`` message to check deprecated
    attributes in the stdlib.
  * Exempt ``TypedDict`` from ``typing_extensions`` from ``too-
    many-ancestor`` checks.
  * Extend broad-exception-raised and broad-exception-caught to
    except*.
  * Fix a false-negative for unnecessary if blocks using a
    different than expected ordering of arguments.
  * For "import X", it will report "(standard/third party/first
    party/local) import X"
  * For "import X.Y" and "from X import Y", it will report
    "(standard/third party/first party/local) import X.Y"
  * The import category is specified to provide explanation as to
    why pylint has issued the message and guidence to the
    developer on how to fix the problem.
  * Fix a crash when an enum class which is also decorated with a
    ``dataclasses.dataclass`` decorator is defined.

- update to 3.0.3:
  * Fixed false positive for ``unnecessary-lambda`` when the call
    has keyword arguments but not the lambda.
  * Fixed incorrect suggestion for shallow copy in unnecessary-
    comprehension
  * After changing b = [x for x in a] to b = a based on the
    suggestion, the script now prints [0, 2, 3]. The correct
    suggestion should be use list(a) to preserve the original
    behavior.
  * Fix false positives for ``undefined-variable`` and ``unused-
    argument`` for classes and functions using Python 3.12 generic
    type syntax.
  * Fixed ``pointless-string-statement`` false positive for
    docstrings on Python 3.12 type aliases.
  * Fix false positive for ``invalid-exception-operation`` when
    concatenating tuples of exception types.
  * Fix a bug where pylint was unable to walk recursively through
    a directory if the directory has an `__init__.py` file.

- Update to version 1.2.1
  * Restore the ability to specify the init-hook option via the
    configuration file, which was accidentally broken in 1.2.0.
  * Add a new warning [bad-continuation] for badly indentend continued
    lines.
  * Emit [assignment-from-none] when the function contains bare returns.
    Fixes BitBucket issue #191.
  * Added a new warning for closing over variables that are
    defined in loops. Fixes Bitbucket issue #176.
  * Do not warn about \u escapes in string literals when Unicode literals
    are used for Python 2.*. Fixes BitBucket issue #151.
  * Extend the checking for unbalanced-tuple-unpacking and
    unpacking-non-sequence to instance attribute unpacking as well.
  * Fix explicit checking of python script (1.2 regression, #219)
  * Restore --init-hook, renamed accidentally into --init-hooks in 1.2.0
    (#211)
  * Add 'indexing-exception' warning, which detects that indexing
    an exception occurs in Python 2 (behaviour removed in Python 3).

- Remove execute bit from a test script to remove an unnecessary
  Requires. (bsc#1199219)

- Switch to regular releases again
- Update to 1.8.3:
  * Various false positives were fixed
  * Many additional python3 tweaks
  * For more see ChangeLog

  enviroments
- Run only python3 tests it takes ages to finish and we should focus
  only on one variant
  * Also few tests currently fail and upstream is aware so put there

- update source url

- Update to version 1.6.4
  see changes in /usr/share/doc/packages/python-pylint/ChangeLog

- Update to version 1.6.1
  see changes in /usr/share/doc/packages/python-pylint/ChangeLog

- Update to version 1.5.5:
  * 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
  * Don't emit unsubscriptable-value for classes with unknown
    base classes.
  * 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.
  * Don't consider bare and broad except handlers as ignoring NameError,
    AttributeError and similar exceptions, in the context of checkers for
    these issues.

- Update to version 1.5.4
  * 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.

- Update to version 1.5.3:
  * 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.
- update to version 1.5.2:
  * 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.
- update to version 1.5.1:
  * 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.
- update to version 1.5.0:
  * long list of changes, see Changelog file for details
- Cleanup update-alternatives

- Update to 1.4.4:
  * Avoid breaking pylint when using logilab.common >= 1.0.

- Update to 1.4.3:
  * Remove three warnings: star-args, abstract-class-little-used,
    abstract-class-not-used. These warnings don't add any real value
    and they don't imply errors or problems in the code.
  * Added a new option for controlling the peephole optimizer in astroid.
    The option ``--optimize-ast`` will control the peephole optimizer,
    which is used to optimize a couple of AST subtrees. The current problem
    solved by the peephole optimizer is when multiple joined strings,
    with the addition operator, are encountered. If the numbers of such
    strings is high enough, Pylint will then fail with a maximum recursion
    depth exceeded error, due to its visitor architecture. The peephole
    just transforms such calls, if it can, into the final resulting string
    and this exhibit a problem, because the visit_binop method stops being
    called (in the optimized AST it will be a Const node).

- Update to 1.4.2:
  * Don't require a docstring for empty modules. Closes issue #261.
  * Fix a false positive with `too-few-format-args` string warning,
    emitted when the string format contained a normal positional
    argument ('{0}'), mixed with a positional argument which did
    an attribute access ('{0.__class__}').
    Closes issue #463.
  * Take in account all the methods from the ancestors
    when checking for too-few-public-methods. Closes issue #471.
  * Catch enchant errors and emit 'invalid-characters-in-docstring'
    when checking for spelling errors. Closes issue #469.
  * Use all the inferred statements for the super-init-not-called
    check. Closes issue #389.
  * Add a new warning, 'unichr-builtin', emitted by the Python 3
    porting checker, when the unichr builtin is found. Closes issue #472.
  * Add a new warning, 'intern-builtin', emitted by the Python 3
    porting checker, when the intern builtin is found. Closes issue #473.
  * Add support for editable installations.
  * The HTML output accepts the `--msg-template` option. Patch by
    Dan Goldsmith.
  * Add 'map-builtin-not-iterating' (replacing 'implicit-map-evaluation'),
    'zip-builtin-not-iterating', 'range-builtin-not-iterating', and
    'filter-builtin-not-iterating' which are emitted by `--py3k` when the
    appropriate built-in is not used in an iterating context (semantics
    taken from 2to3).
  * Add a new warning, 'unidiomatic-typecheck', emitted when an explicit
    typecheck uses type() instead of isinstance(). For example,
    `type(x) == Y` instead of `isinstance(x, Y)`. Patch by Chris Rebert.
    Closes issue #299.
  * Add support for combining the Python 3 checker mode with the --jobs
    flag (--py3k and --jobs). Closes issue #467.
  * Add a new warning for the Python 3 porting checker, 'using-cmp-argument',
    emitted when the `cmp` argument for the `list.sort` or `sorted builtin`
    is encountered.
  * Make the --py3k flag commutative with the -E flag. Also, this patch
    fixes the leaks of error messages from the Python 3 checker when
    the errors mode was activated. Closes issue #437.

- Update to 1.4.1:
  * Look only in the current function's scope for bad-super-call.
    Closes issue #403.
  * Check the return of properties when checking for not-callable.
    Closes issue #406.
  * Warn about using the input() or round() built-ins for Python 3.
    Closes issue #411.
  * Proper abstract method lookup while checking for
    abstract-class-instantiated. Closes issue #401.
  * Use a mro traversal for finding abstract methods. Closes issue #415.
  * Fix a false positive with catching-non-exception and tuples of
    exceptions.
  * Fix a false negative with raising-non-exception, when the raise used
    an uninferrable exception context.
  * Fix a false positive on Python 2 for raising-bad-type, when
    raising tuples in the form 'raise (ZeroDivisionError, None)'.
  * Fix a false positive with invalid-slots-objects, where the slot entry
    was an unicode string on Python 2. Closes issue #421.
  * Add a new warning, 'redundant-unittest-assert', emitted when using
    unittest's methods assertTrue and assertFalse with constant value
    as argument. Patch by Vlad Temian.
  * Add a new JSON reporter, usable through -f flag.
  * Add the method names for the 'signature-differs' and 'argument-differs'
    warnings. Closes issue #433.
  * Don't compile test files when installing.
  * Fix a crash which occurred when using multiple jobs and the files
    given as argument didn't exist at all.

- Lower tk dependency to Recommends as it's only needed for optional GUI

- Update to 1.4.0:
  * Added new options for controlling the loading of C extensions.
    By default, only C extensions from the stdlib will be loaded
    into the active Python interpreter for inspection, because they
    can run arbitrary code on import. The option
    `--extension-pkg-whitelist` can be used to specify modules
    or packages that are safe to load.
  * Change default max-line-length to 100 rather than 80
  * Drop BaseRawChecker class which were only there for backward
    compat for a while now
  * Don't try to analyze string formatting with objects coming from
    function arguments. Closes issue #373.
  * Port source code to be Python 2/3 compatible. This drops the
    need for 2to3, but does drop support for Python 2.5.
  * Each message now comes with a confidence level attached, and
    can be filtered base on this level. This allows to filter out
    all messages that were emitted even though an inference failure
    happened during checking.
  * Improved presenting unused-import message. Closes issue #293.
  * Add new checker for finding spelling errors. New messages:
    wrong-spelling-in-comment, wrong-spelling-in-docstring.
    New options: spelling-dict, spelling-ignore-words.
  * Add new '-j' option for running checks in sub-processes.
  * Added new checks for line endings if they are mixed (LF vs CRLF)
    or if they are not as expected. New messages: mixed-line-endings,
    unexpected-line-ending-format. New option: expected-line-ending-format.
  * 'dangerous-default-value' no longer evaluates the value of the arguments,
    which could result in long error messages or sensitive data being leaked.
    Closes issue #282
  * Fix a false positive with string formatting checker, when
    encountering a string which uses only position-based arguments.
    Closes issue #285.
  * Fix a false positive with string formatting checker, when using
    keyword argument packing. Closes issue #288.
  * Proper handle class level scope for lambdas.
  * Handle 'too-few-format-args' or 'too-many-format-args' for format
    strings with both named and positional fields. Closes issue #286.
- Switched to tar.gz upstream

- Update to 1.3.1:
  * Fix a false positive with string formatting checker, when
    encountering a string which uses only position-based arguments.
    Closes issue #285.
  * Fix a false positive with string formatting checker, when using
    keyword argument packing. Closes issue #288.
  * Handle 'too-few-format-args' or 'too-many-format-args' for format
    strings with both named and positional fields. Closes issue #286.
