* Ignore elements of sequences when converting them to AST with const_factoryClaudiu Popa2015-12-111-1/+11
| | | | | | | | | | | | | | | const_factory is buggy in master, as well as the entire raw_building module, which means that at given points during rebuilding of ASTs from live objects, nodes are constructed with Python objects as elements, leading to various crashes with pylint and with astroid during certain inference paths. This is fixed in 2.0 though, where raw_building was completely rewritten, but bringing those changes back into master will need some more work to be done. Until this happens, we ignore the elements of sequences passed to const_factory, since they are not useful in anyway (and the code that uses them crashes anyway). This is just a temporary solution until we either merge master with 2.0 or backport raw_building changes from 2.0 to master.
* Some nodes got a new attribute, 'ctx', which tells in which context the said ↵Claudiu Popa2015-12-081-0/+25
| | | | | | | | | | | | | | | | | | | node was used. The possible values for the contexts are `Load` ('a'), `Del` ('del a'), `Store` ('a = 4') and the nodes that got the new attribute are Starred, Subscript, List and Tuple. The builtin ast module provides contexts for Name and Attribute as well, but we took a different approach in the past, by having different nodes for each type of context. For instance, Name used in a Del context is a DelName, while Name used in a Store context is AssignName. Since this is ingrained in astroid since quite some time, it makes no sense to change them as well, even though it's a loss of consistency. The patch introduces a new dependency to enum34 on older Python versions, which is used for building the three possible enum values for the contexts. Closes issue #267.

| | | | | | | They used to have different signatures and each one made assumptions about what could be passed to other implementations, leading to various possible crashes when one or more arguments weren't given. Closes issue #277.

| * This bookmark adds structured exceptions to astroid.Ceridwen2015-11-021-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Major changes: * AstroidError has an __init__ that accepts arbitrary keyword-only arguments for adding information to exceptions, and a __str__ that lazily uses exception attributes to generate a message. The first positional argument to an exception is assigned to .message. The new API should be fully backwards compatible in general. * Some exceptions are combined or renamed; the old names are still available. * The OperationErrors used by pylint are now BadOperationMessages and located in util.py. * The AstroidBuildingException in _data_build stores the SyntaxError in its .error attribute rather than args[0]. * Many places where exceptions are raised have new, hopefully more useful error messages. The only major issue remaining is how to propagate information into decorators.
* | Handle the cases when a List can contain Uninferable as its elementsClaudiu Popa2015-11-231-0/+3
| | | | | | | | | | | | | | This can happen for instance when the list contains objects which weren't inferable in the first place. There were a bunch of places affected by this bug: unpack_infer, the inference of list additions and the handling of the namedtuple's fields.

* Final draft of state printing after mergeCeridwen2015-09-131-7/+20
|\ | | | | | | | | | | | | | | | | | | | | | | | | This patch adds __str__` and `__repr__` methods to InferenceContext and alters the `__str__, `__repr__, and repr_tree() methods for NodeNG. The `__str__` methods print out formatted information about the object's fields; NodeNG's `__str__` method is not recursive. InferenceContext's __repr__` gives a compact representation of its fields. I slightly shortened NodeNG's `__repr__` method by removing a field that's usually empty. I rewrote repr_tree() to better format the information it contains and to display *all* the fields for each AST node, with some fields controlled by options to avoid spam. I also fixed https://bitbucket.org/logilab/astroid/issues/185/as_string-gives-wrong-result-for-keyword .

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cleanup consisted in a couple of changes: * import only modules, not objects, in order to not clutter the module namespace and to not leak accidentally objects which aren't public API for the said modules. * use two spaces between module level functions * move some mixins from astroid.node_classes in the proper order, starting at the left, not being last in the MRO.
| * Move InferenceContext and CallContext into astroid.contextClaudiu Popa2015-08-121-2/+3
| | | | | | | | | | | | | | 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.

* | Refactor node classes to have constructors and change some names.Ceridwen2015-07-101-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I corrected the spelling of 'infered' to 'infered' and changed some to make them more consistent with the built-in ast module and to read better in English. I created aliases with proxy objects to maintain backwards compatibility. I also refactored the node classes so that they have __init__ and postinit functions. The postinit function has to be called after the creation of a parent with the instances of its children because the node __init__ functions have to take a parent instance to maintain the doubly-linked structure of the AST. This involved moving considerable amounts of node-construction logic from rebuilder.py to node_classes.py and scoped_nodes.py.
