astroid 2.4.0

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 pylint-dev/pylint#2335

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

  Close pylint-dev/pylint#2334

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

  Close pylint-dev/pylint#1078

• Infer qualified classmethod as a classmethod.

• 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 pylint-dev/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 pylint-dev/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 pylint-dev/pylint#2985

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

  Close pylint-dev/pylint#3414

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

  Close pylint-dev/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 pylint-dev/pylint#1285

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

  Close pylint-dev/pylint#3332

• Skip non Assign and AnnAssign nodes from enum reinterpretation

  Closes pylint-dev/pylint#3365

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

  Close pylint-dev/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 pylint-dev/pylint#2911
  Close pylint-dev/pylint#3214

• Added some functions to the brain_numpy_core_umath module

  Close pylint-dev/pylint#3319

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

  Close pylint-dev/pylint#2885

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

  Close pylint-dev/pylint#3306

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

  Close pylint-dev/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 pylint-dev/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 pylint-dev/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 pylint-dev/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 pylint-dev/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.

astroid 2.3.2

• All type comments have as parent the corresponding astroid node

  Until now they had as parent the builtin ast node which meant
  we were operating with primitive objects instead of our own.

  Close pylint-dev/pylint#3174

• Pass an inference context to metaclass() when inferring an object type

  This should prevent a bunch of recursion errors happening in pylint.
  Also refactor the inference of IfExp nodes to use separate contexts
  for each potential branch.

  Close pylint-dev/pylint#3159

astroid 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

astroid 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 pylint-dev/pylint#2333

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

  Close pylint-dev/pylint#2859

• 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 pylint-dev/pylint#2841

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

  Close pylint-dev/pylint#2777

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