| * Changed the way how parameters are being builtClaudiu Popa2016-02-135-149/+215
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old way consisted in having the parameter names, their defaults and their annotations separated in different components of the Arguments node. We introduced a new Param node, which holds the name of a parameter, its default value and its annotation. If any of the last two values are missing, then that slot will be filled with a new node kind, Empty, which is used for specifying the lack of something (None could have been used instead, but that means having non-AST nodes in the Arguments node). We're also having support for positional only arguments, for the moment only in raw_building. Close #215
| * Don't set the fromlineno of parents or children for nodes without it setClaudiu Popa2016-01-252-31/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | If a node had a .fromlineno as None, then a function would be invoked which retrieved the first line number of the children or the parents which wasn't none. This is wrong, because it's not a guarantee that all nodes should have it set, especially those coming from raw_building, where it can be close to impossible to determine the line number of an object coming from an extension module. The functionality was removed and certain guards were added in a couple of places in order to protect operations against None. Close #310 and #195

| | | | | | | | | | | | When looking up a name in a scope, Scope.lookup will return only the values which will be reachable after execution, as seen in the following code: a = 1 a = 2 In this case it doesn't make sense to return two values, but only the last one.

* Use keys and values as separate arguments for nodes.DictClaudiu Popa2016-01-043-13/+26
| | | | | | | | Dict was a bit different that the corresponding class from the builtin ast module with respect to how it was initialized. Instead of accepting a list of pairs, the initializer accepts two arguments, one for keys, the other for values. For backward compatibility, the class gained a new .items property.

* Lambda is no longer at the top of the FunctionDef.Claudiu Popa2016-01-031-51/+59
| | | | | | This means that checks such as ``isinstance(node, Lambda)`` will not hold true anymore for Functions. Closes #291

* Move mixins into tree.base.Claudiu Popa2016-01-023-25/+239
| | | | | | The mixins are better off in tree.base, rather than having their own module. They are also used only by the AST nodes. Close #292
* Remove do_import_module and real_name from ImportFrom and Import nodes.Claudiu Popa2016-01-021-2/+8
| | | | | | | | | | | | | | do_import_module was broken for Import, since it was relying on a missing attribute `modname`. do_import_module in fact required all the time for a name parameter to be passed as an argument. The inherent problem is that Import doesn't have an underlying module name, but more of them, in the .names attribute. Thus requiring for do_import_module to pick one name from .names or to return multiple modules was deemed inappropiate and the method became a function which always requires the import name to be given. do_import_module and real_name are now functions in interpreter.util. Closes #293
* Move qname() definition into a separate mixinClaudiu Popa2015-12-301-3/+13
| | | | | | | | The new mixin is used by ClassDef, Lambda, FunctionDef and Module, for defining a qname() method on them. This should fix a bug where the qname was defined on any subclass of LocalsDictNode, even though it wasn't possible to get a qualified name for the node in question. Closes #278.
* Move lookup specific bits into interpreter.lookupClaudiu Popa2015-12-291-280/+11
| | | | | | | | | | | This patch moves code which was targeted for implementing lookup support from scoped_nodes into interpreter.lookup, resulting in a more cohesive scoped_nodes module. The lookup functions were capable of using virtual base classes instead on relying on concrete classes offered by node_classes and scoped_nodes. The only minor complaint is that builtin_lookup still needs to depend on the manager, which is lazily loaded inside the function itself, at least until we'll get rid of this circular dependency.

* The slots() method conflates all the slots from the ancestors into a list of ↵Claudiu Popa2015-12-291-10/+30
| | | | | | | | current and parent slots. We're doing this because this is the right semantics of slots, they get inherited, as long as each parent defines a __slots__ entry.
* Some nodes got a new attribute, 'ctx', which tells in which context the said ↵Claudiu Popa2015-12-082-232/+265
| | | | | | | | | | | | | | | | | | | 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.

* Add two new exceptions, AstroidImportError and AstroidSyntaxError.Claudiu Popa2015-12-061-1/+1
| | | | | | | | They are subclasses of AstroidBuildingException and are raised when a module can't be imported from various reasons. Also do_import_module lets the errors to bubble up without converting them to InferenceError. This particular conversion happens only during the inference.
* assigned_stmts methods have the same signature from now on.Claudiu Popa2015-12-051-0/+1
| | | | | | | 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.
