astroid 2.4.0

on GitHub

Release Date: 2020-04-27

• Expose a ast_from_string method in AstroidManager, which will accept
  source code as a string and return the corresponding astroid object

  Closes #725

• BoundMethod.implicit_parameters returns a proper value for __new__

  Close PyCQA/pylint#2335

• Allow slots added dynamically to a class to still be inferred

  Close PyCQA/pylint#2334

• Allow FunctionDef.getattr to look into both instance attrs and special attributes

  Close PyCQA/pylint#1078

• Infer qualified classmethod as a classmethod.

  Close PyCQA/pylint#3417

• Prevent a recursion error to happen when inferring the declared metaclass of a class

  Close #749

• Raise AttributeInferenceError when getattr() receives an empty name

  Close PyCQA/pylint#2991

• Prevent a recursion error for self reference variables and type() calls.

  Close #199

• Do not infer the first argument of a staticmethod in a metaclass as the class itself

  Close PyCQA/pylint#3032

• NodeNG.bool_value() gained an optional context parameter

  We need to pass an inference context downstream when inferring the boolean
  value of a node in order to prevent recursion errors and double inference.

  This fix prevents a recursion error with dask library.

  Close PyCQA/pylint#2985

• Pass a context argument to astroid.Arguments to prevent recursion errors

  Close PyCQA/pylint#3414

• Better inference of class and static methods decorated with custom methods

  Close PyCQA/pylint#3209

• Reverse the order of decorators for infer_subscript

  path_wrapper needs to come first, followed by raise_if_nothing_inferred,
  otherwise we won't handle StopIteration correctly.

  Close #762

• Prevent a recursion error when inferring self-referential variables without definition

  Close PyCQA/pylint#1285

• Numpy datetime64.astype return value is inferred as a ndarray.

  Close PyCQA/pylint#3332

• Skip non Assign and AnnAssign nodes from enum reinterpretation

  Closes PyCQA/pylint#3365

• Numpy ndarray attributes imag and real are now inferred as ndarray.

  Close PyCQA/pylint#3322

• Added a call to register_transform for all functions of the brain_numpy_core_multiarray
  module in case the current node is an instance of astroid.Name

  Close #666

• Use the parent of the node when inferring aug assign nodes instead of the statement

  Close PyCQA/pylint#2911
  Close PyCQA/pylint#3214

• Added some functions to the brain_numpy_core_umath module

  Close PyCQA/pylint#3319

• Added some functions of the numpy.core.multiarray module

  Close PyCQA/pylint#3208

• All the numpy ufunc functions derived now from a common class that
  implements the specific reduce, accumulate, reduceat,
  outer and at methods.

  Close PyCQA/pylint#2885

• nodes.Const.itered returns a list of Const nodes, not strings

  Close PyCQA/pylint#3306

• The shape attribute of a numpy ndarray is now a ndarray

  Close PyCQA/pylint#3139

• Don't ignore special methods when inspecting gi classes

  Close #728

• Added transform for scipy.gaussian

• Add suport for inferring properties.

• Added a brain for responses

• Allow inferring positional only arguments.

• Retry parsing a module that has invalid type comments

  It is possible for a module to use comments that might be interpreted
  as type comments by the ast library. We do not want to completely crash on those
  invalid type comments.

  Close #708

• Scope the inference to the current bound node when inferring instances of classes

  When inferring instances of classes from arguments, such as self
  in a bound method, we could use as a hint the context's boundnode,
  which indicates the instance from which the inference originated.
  As an example, a subclass that uses a parent's method which returns
  self, will override the self to point to it instead of pointing
  to the parent class.

  Close PyCQA/pylint#3157

• Add support for inferring exception instances in all contexts

  We were able to infer exception instances as ExceptionInstance
  only for a handful of cases, but not all. ExceptionInstance has
  support for better inference of .args and other exception related
  attributes that normal instances do not have.
  This additional support should remove certain false positives related
  to .args and other exception attributes in pylint.

  Close PyCQA/pylint#2333

• Add more supported parameters to subprocess.check_output

  Close #722

• Infer args unpacking of self

  Certain stdlib modules use *args to encapsulate
  the self parameter, which results in uninferable
  instances given we rely on the presence of the self
  argument to figure out the instance where we should be
  setting attributes.

  Close PyCQA/pylint#3216

• Clean up setup.py

  Make pytest-runner a requirement only if running tests, similar to what was
  done with McCabe.

  Clean up the setup.py file, resolving a handful of minor warnings with it.

• Handle StopIteration error in infer_int.

  Close PyCQA/pylint#3274

• Can access per argument type comments for positional only and keyword only arguments.

  The comments are accessed through through the new
  Arguments.type_comment_posonlyargs and
  Arguments.type_comment_kwonlyargs attributes respectively.

• Relax upper bound on wrapt

  Close #755

• Properly analyze CFFI compiled extensions.
