Summary Possible RetainPtr misuse in WKScriptMessage.mm - could leak

RetainPtr<...>::operator= will +1. This looks like a possible missing adoptNS which could cause a leak: > Source/WebKit2/UIProcess/API/Cocoa/WKScriptMessage.mm:47:5: > _body = [body copy]; > ^ However, since _body is RetainPtr<id>, how does this even work? "id" doesn't necessary respond to retain/release/copy. It looks like this could come from -[JSValue toObject] which returns id, but probably could return id<NSObject>.

Maybe id is always guaranteed to at least be an NSObject. In that case we can just adoptNS.

Created attachment 236957 [details] [PATCH] Proposed Fix This is an untested fix. Seeing as we are arbitrarily calling -copy, then -retain/-release should be fine for now.
