Changelog

Sourced from astroid's changelog.

What's New in astroid 2.1.0?

Release Date: 2018-11-25

• threading.Lock.acquire has the timeout parameter now.

  Close threading lock.acquire unexpected-keyword-arg timeout pylint-dev/pylint#2457

• Pass parameters by keyword name when inferring sequences.

  Close getting "AttributeError: 'NoneType' object has no attribute 'statement'" for small piece of code pylint-dev/pylint#2526

• Correct line numbering for f-strings for complex embedded expressions

  When a f-string contained a complex expression, such as an attribute access,
  we weren't cloning all the subtree of the f-string expression for attaching the correct
  line number. This problem is coming from the builtin AST parser which gives for the f-string
  and for its underlying elements the line number 1, but this is causing all sorts of bugs and
  problems in pylint, which expects correct line numbering.

  Close The disable declaration directives does not take effect when f-string exists pylint-dev/pylint#2449

• Add support for argparse.Namespace

  Close argparse.Namespace usage causes E1101(no-member) pylint-dev/pylint#2413

• async functions are now inferred as AsyncGenerator when inferring their call result.

• Filter out Uninferable when inferring the call result result of a class with an uninferable __call__ method.

  Close TypeError: 'Uninferable' object is not iterable pylint-dev/pylint#2434

• Make compatible with AST changes in Python 3.8.

• Subscript inference (e.g. "a[i]") now pays attention to multiple inferred values for value
  (e.g. "a") and slice (e.g. "i")

  Close #614
