[SelfInBlock] Check for when weakSelf is used in a no escaping block Summary: This adds a check for when developers use weakSelf (and maybe strongSelf) in a block, when there is no need for it, because it won't cause a retain cycle. In general there is an annotation in Objective-C for methods that take blocks, NS_NOESCAPE, that means that the passed block won't leave the scope, i.e. is "no escaping". So we report when weakSelf is used and the block has the annotation. Reviewed By: ngorogiannis Differential Revision: D19662468 fbshipit-source-id: f5ac695aa

[SelfInBlock] Reporting strongSelf Not Checked only in field access Summary: After receiving feedback about this, I'm changing the reporting of strongSelf Not Checked to only in cases where it can cause a crash. Here I'm adding reporting for field access, and removing general reporting. In a next diff, I'll also add reporting for passing strongSelf to methods in not explicitly nullable positions.

[selfInBlock] Add a new check when strongSelf is captured in a (sub)block. Summary: Adding a new check as part of the SelfInBlock checker, for cases when a strong pointer to self, that is not self, is captured in the block. This will cover the following wrong scenarios: 1. strongSelf is a local variable in a block as it should be, and then it's used in a sub-block, in which case it's a captured variable. 2. weakSelf is defined without the weak attribute by mistake.

[selfInBlock] Remove false positive from mix self weakSelf Summary: The translation of closures includes a load instruction for the captured variable, then we add that corresponding id to the closure. This doesn't correspond to an actual "use" of the captured variable in the source program though, and causes false positives. Here we remove the ids from the domain when that id is being added to a closure. Reviewed By: ngorogiannis Differential Revision: D19557352 fbshipit-source-id: 52b426011
