* Squash one-off inference utility functions to help reduce recursion errors ↵Bryce Guinta2020-06-231-1/+19
| | | | | | | (#804) This also makes debugging a lot simpler reducing the complexity of the function stack.

* Infer the __len__ result of a subclass of an integerClaudiu Popa2020-03-101-2/+11
| | | | | Rather than failing the inference altogether, we can infer the default int value for subclasses of ints.
* Pass an inference context to `metaclass()` when inferring an object typeClaudiu Popa2019-10-181-1/+1
| | | | | | | | | 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 PyCQA/pylint#3152 Close PyCQA/pylint#3159

* infer_call_result can raise InferenceError so make sure to handle that for ↵Claudiu Popa2018-07-311-5/+1
| | | | | | | | | | | the call sites where it is used infer_call_result started recently to raise InferenceError for objects for which it could not find any returns. Previously it was silently raising a StopIteration, which was especially leaking when calling builtin methods. Since it is after all an inference method, it is expected that it could raise an InferenceError rather than returning nothing. Close PyCQA/pylint#2350

| | | | This is in a similar vein with the `isinstance` builtin, with minor changes.
* Replace handling of AstroidError with MroErrorClaudiu Popa2018-03-051-2/+0
| | | | | I'm not sure why AstroidError was added in the first place, as this is the most general exception in astroid.

| * Move InferenceContext and CallContext into astroid.contextClaudiu Popa2015-08-121-1/+2
| | | | | | | | | | | | | | In order to reduce circular dependencies between components, CallContext is moved into a new module, astroid.context. At the same time, for increasing the cohesion inside astroid.bases, InferenceContext was moved as well into astroid.context.
| * Move YES to astroid.util.Claudiu Popa2015-08-091-4/+5
| | | | | | | | | | | | | | YES is needed by other components of astroid, components which aren't necessarily related to astroid.bases. In order to reduce circular interdependencies between components, YES is moved into a new module, tailored for various *utilities*.
