v2.17.0

Compare Source

2.17 is a small release that is the first to support python 3.11 officially
with the addition of TryStar nodes.

There's still two new default checks: bad-chained-comparison and
implicit-flag-alias, one of them already fixed a previously undetected
bug in sentry.

Thanks to the community effort our documentation is almost complete,
and almost all messages should have a proper documentation now.
A big thank you to everyone who participated !

The next release is going to be 3.0.0, bring breaking changes and
enact long announced deprecations. There's going to be frequent beta
releases, before the official releases, everyone is welcome to try the betas
so we find problems before the actual release.

Summary -- Release highlights

In 2.16.0 we added aggregation and composition understanding in pyreverse, and a way to clear
the cache in between run in server mode (originally for the VS Code integration). Apart from the bug
fixes there's also a lot of new checks, and new extensions that have been asked for for a long time
that were implemented.

If you want to benefit from all the new checks load the following plugins::

pylint.extensions.dict_init_mutate,
pylint.extensions.dunder,
pylint.extensions.typing,
pylint.extensions.magic_value,

We still welcome any community effort to help review, integrate, and add good/bad examples to the doc for
#​5953. This should be doable without any pylint or astroid
knowledge, so this is the perfect entrypoint if you want to contribute to pylint or open source without
any experience with our code!

Last but not least @​clavedeluna and @​nickdrozd became triagers, welcome to the team !

What's new in Pylint 2.16.0?

Changes requiring user actions

• The accept-no-raise-doc option related to missing-raises-doc will now
  be correctly taken into account all the time.

  Pylint will no longer raise missing-raises-doc (W9006) when no exceptions are
  documented and accept-no-raise-doc is true (issue #​7208).
  If you were expecting missing-raises-doc errors to be raised in that case,
  you
  will now have to add accept-no-raise-doc=no in your configuration to keep
  the same behavior.
  Closes #​7208

New Features

• Added the no-header output format. If enabled with
  --output-format=no-header, it will not include the module name in the
  output.
  Closes #​5362

• Added configuration option clear-cache-post-run to support server-like
  usage.
  Use this flag if you expect the linted files to be altered between runs.
  Refs #​5401

• Add --allow-reexport-from-package option to configure the
  useless-import-alias check not to emit a warning if a name
  is reexported from a package.
  Closes #​6006

• Update pyreverse to differentiate between aggregations and compositions.
  pyreverse checks if it's an Instance or a Call of an object via method
  parameters (via type hints)
  to decide if it's a composition or an aggregation.
  Refs #​6543

New Checks

• Adds a pointless-exception-statement check that emits a warning when an
  Exception is created and not assigned, raised or returned.
  Refs #​3110

• Add a shadowed-import message for aliased imports.
  Closes #​4836

• Add new check called unbalanced-dict-unpacking to check for unbalanced
  dict unpacking
  in assignment and for loops.
  Closes #​5797

• Add new checker positional-only-arguments-expected to check for cases
  when
  positional-only arguments have been passed as keyword arguments.
  Closes #​6489

• Added singledispatch-method which informs that @singledispatch should
  decorate functions and not class/instance methods.
  Added singledispatchmethod-function which informs that
  @singledispatchmethod should decorate class/instance methods and not
  functions.
  Closes #​6917

• Rename broad-except to broad-exception-caught and add new checker
  broad-exception-raised
  which will warn if general exceptions BaseException or Exception are
  raised.
  Closes #​7494

• Added nested-min-max which flags min(1, min(2, 3)) to simplify to
  min(1, 2, 3).
  Closes #​7546

• Extended use-dict-literal to also warn about call to dict() when
  passing keyword arguments.
  Closes #​7690

• Add named-expr-without-context check to emit a warning if a named
  expression is used outside a context like if, for, while, or
  a comprehension.
  Refs #​7760

• Add invalid-slice-step check to warn about a slice step value of 0
  for common builtin sequences.
  Refs #​7762

• Add consider-refactoring-into-while-condition check to recommend
  refactoring when
  a while loop is defined with a constant condition with an immediate if
  statement to check for break condition as a first statement.
  Closes #​8015

Extensions

• Add new extension checker dict-init-mutate that flags mutating a
  dictionary immediately
  after the dictionary was created.
  Closes #​2876

• Added bad-dunder-name extension check, which flags bad or misspelled
  dunder methods.
  You can use the good-dunder-names option to allow specific dunder names.
  Closes #​3038

• Added consider-using-augmented-assign check for CodeStyle extension
  which flags x = x + 1 to simplify to x += 1.
  This check is disabled by default. To use it, load the code style extension
  with load-plugins=pylint.extensions.code_style and add
  consider-using-augmented-assign in the enable option.
  Closes #​3391

• Add magic-number plugin checker for comparison with constants instead of
  named constants or enums.
  You can use it with --load-plugins=pylint.extensions.magic_value.
  Closes #​7281

• Add redundant-typehint-argument message for typing plugin for duplicate
  assign typehints.
  Enable the plugin to enable the message with:
  --load-plugins=pylint.extensions.typing.
  Closes #​7636

  change, it would silently fail to register the plugin for use, but would load

  Closes #​7570

  Closes #​7635.

Internal Changes

• Add and fix regression tests for plugin loading.
  This shores up the tests that cover the loading of custom plugins as affected
  by any changes made to the sys.path during execution of an init-hook.
  Given the existing contract of allowing plugins to be loaded by fiddling with
  the path in this way, this is now the last bit of work needed to close Github
  issue #​7264.
  Closes #​7264
