* Fix false positive when map() receives iterableTiago Honorato2021-02-201-0/+1
| | | | | | | Since map() supports iterables, it should not issue builtin-not-iterating for iterable arguments. Signed-off-by: Tiago Honorato <tiagohonorato1@gmail.com>

* Fix false positive for inverse containment testsAthos Ribeiro2020-01-061-1/+1
| | | | | | | | | | | | While dict-keys-not-iterating does not generate false positives for the 'in' containment test, the check does generate false positives for the inverse counterpart of the containment test, 'not in'. This patch changes the check behavior to also consider the 'not in' operator as an iterating context. * Relates to #2186 Signed-off-by: Athos Ribeiro <athoscr@fedoraproject.org>

* Speedup py3k modeHugues Bruant2019-10-301-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | Avoid costly inference in visit_call and visit_attribute when the attribute name is one that cannot possibly trigger a message. This typically leads to a 30-50% speedup when running pylint in python3 porting mode on most codebases. Benchmark results on pylint's own code, on a 2018 macbook pro, with python 3.6.8, using `hyperfine`. pylint-2.4.2 ``` Time (mean ± σ): 10.071 s ± 1.136 s [User: 9.724 s, System: 0.246 s] Range (min … max): 9.352 s … 12.015 s 5 runs ``` pylint-2.4.2 + this patch ``` Time (mean ± σ): 6.282 s ± 0.046 s [User: 6.099 s, System: 0.155 s] Range (min … max): 6.232 s … 6.327 s 5 runs ```
* Fixes "exception-escape" false positive with generators (#3128) (#3182)Gabriel R Sezefredo2019-10-161-9/+4
| | | | | | | As reported on #3128, there is a bug when the handler bound object is being used inside a generator causing a false positive. This was due to the way we were identifying if the object was "inside" its handler or not. In the previous implementation we would visit the node parents until we reached the object scope (in the generator case, the scope of the node is the generator, not the handler), while this change continues to go up the parent stack until it reaches its parent handler, or, if it's not inside its handler, it reaches the module's parent (None). Object is considered inside its handler if it reaches it by going up in the parent chain. It's considered outside its handler if it reaches None. Signed-off-by: Gabriel R Sezefredo <g@briel.dev>
* Remove redundant compatibility code (#3097)Hugo van Kemenade2019-09-121-20/+11
| | | | We no longer support Python 2 so we can remove the compatibility code we had in place for that version.
* Do not scope the iterating contexts to builtinsClaudiu Popa2019-09-101-2/+1
| | | | | | | This caused issues detecting that `OrderedDict` and similar non-builtin predefined iterable consumers where not in fact in an *iterating* context. Close #3075
* [pylint.checkers] Make the link between msgid and symbol strictly 1-1Pierre Sassoulas2019-08-191-6/+6
| | | | | Will permit to improve performance with less check but more importantly simplify the message store a lot.

* Refactor - Avoid intra-packages circular dependencies for constantsPierre Sassoulas2019-03-291-1/+1
| | | | | | | | Some constants were package internal but were used by multiple packages. This created circular dependencies. By creating a file for constants we make sure this does not happen because we won't import everything important in this file and every thing else can depend on it.

* Adding implicit-str-concat-in-sequence check (#1655)Lucas Cimon2018-10-101-5/+5
| | | | | ``implicit-str-concat-in-sequence`` detects string concatenation inside lists, sets & tuples. It would warn on code such as `('a', 'b' 'c')`.

| | | | | | | | | | | | | 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
