* Need to also use the builtin module for Python 2Claudiu Popa2018-07-241-0/+3

* `chain.from_iterable` no longer emits `dict-{}-not-iterating` when dealing ↵Claudiu Popa2018-07-241-1/+2
| | | | with dict values and keys
* frozenset is an iterating context for dict.values() and friendsClaudiu Popa2018-07-241-1/+1

* [].extend and similar builtin operations don't emit `dict-*-not-iterating` ↵Claudiu Popa2018-07-241-0/+13
| | | | | | with the Python 3 porting checker Close #2187
* `in` is considered iterating context for some of the Python 3 porting checkersClaudiu Popa2018-06-141-0/+5
| | | | Close #2186
* min() and max() accept iterators (#2138)Anthony Sottile2018-06-061-1/+2

* Check that the potential leaked names are not used in the except handlerClaudiu Popa2018-06-011-0/+8
|
* Don't use scope() to check if the variable is defined in the current statementClaudiu Popa2018-06-011-1/+1
| | | | | | | This works on Python 3 because scope() for a ListComp will always be the ListComp, but on Python 2 that's going to be the outer scope/frame instead. Close #2106
* Make sure the value is not defined in the same comprehension when looking ↵Claudiu Popa2018-05-241-1/+8
| | | | for comprehension-escape values. Close #2106
* Don't include excepthandlers that don't have a name when looking for ↵Claudiu Popa2018-05-231-0/+3

* Rewrite the comprehension-escape and exception-escape to work only on the ↵Claudiu Popa2018-05-231-33/+56
| | | | | | | | | | | | | corresponding nodes These two checks were implemented in terms of visit_namne, that is, for every name in the tree, we looked to see if that name leaked. This was resulting in a couple of false positives and also in a performance issue, since we were calling nodes_of_class() and scope() for each name node. Instead, this approach uses the visit methods for exception and comprehension nodes and looks to see from there if the current scope uses leaked names. This is not the ideal situation as well, ideal would be to have access to the definition frame of each name, but that requires some extra engineering effort in astroid to get it right. Close #2106
* Use last previous assignment for comprehension-escape (#2131)Anthony Sottile2018-05-221-3/+4

* old-raise-syntax can be triggered only on Python 2Claudiu Popa2018-05-161-3/+5

* Fix lintClaudiu Popa2018-05-131-4/+6
|
* Reimplement the lookup() call by manually looking for the right nodesClaudiu Popa2018-05-131-13/+28
| | | | | | On Python 3 we can't see the assignment statement of a deleted node, such as an assignment from a loop or from the except handler. Instead of relying on lookup() itself, look through the current scope manually for the right objects.
* Added two new Python 3 porting checks, `exception-escape` and ↵Claudiu Popa2018-05-121-1/+27
| | | | | | | `comprehension-escape` These two are emitted whenever pylint detects that a variable defined in the said blocks is used outside of the given block. On Python 3 these values are deleted.
* Emit a warning when sys.exc_clear is accessedClaudiu Popa2018-05-111-0/+7
|
* Emit a warning when .xreadlines() is accessedClaudiu Popa2018-05-111-5/+13

* Add new check py3k invalid-unicode-literal. (#2068)Sushobhit2018-05-091-0/+7
| | | Close #1938
* Rip invalid-raise-syntax, we already have old-raise-syntaxClaudiu Popa2018-04-181-20/+5
| | | | | Instead of adding a new check, old-raise-syntax was modified to account for the case when we throw with a traceback.
* Handle dict subclasses for dict-not-iterating checksClaudiu Popa2018-04-181-7/+8
|
* defaultdict and subclasses of dict are now handled for dict-iter-* checksClaudiu Popa2018-04-181-2/+9
