* Use safe_infer for inference of elements in list multiplication operationfix-list-multiplicationDmitry Pribysh2015-10-241-3/+4
| | | | | Now inference yields YES instead of list item value when multiple values are inferred for one list item.
* Fix inference of list multiplication operation.Dmitry Pribysh2015-10-242-3/+19
| | | | | | | | | Old implementation was pushing all the possible values inferred from a node into a list, thus creating extra items in case when there are multiple infered values yielded. New implementation takes only first infered value, preserving the expected size of the list. Fixes pylint's #559.

|\ | | | | | | Fix binary operator inference issue from pylint's #646
| * Fix binary operation inference crash by using cloned contextsbinop-inference-fixDmitry Pribysh2015-10-211-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Idea is that we shouldn't use the same context to infer left-hand side and right-hand side of the binary operation because inferring lhs may leave some metadata in context.path that is irrelevant (and can even break inference) to inference of rhs. So we make two clones of the original context and use them to infer left-hand side and right-hand side independently. And then we use the original context to infer the result of the operation applied to inferred values. This patch fixes pylint's issue #646 and may be also related to other similar astroid issues (#198, #199).

| | | | | | | | | PEP 448 This is a different approach than what the builtin ast module does, since it just uses None to represent this kind of operation, which seems conceptually wrong, due to the fact the AST contains non-AST nodes. Closes issue #206.

* Move objects.Slice back into nodes.SliceClaudiu Popa2015-10-034-49/+37
| | | | | | We did this because objects.Slice had more capabilities than nodes.Slice, such as inferring the slice attributes (start, stop, step) and it was used mostly for inferring the slice() builtin.
