107163 2013-01-17 13:01:31 -0800 Objective-C API: Clean up JSValue.mm 2013-01-17 18:35:14 -0800 1 1 1 Unclassified WebKit JavaScriptCore 528+ (Nightly build) Unspecified Unspecified RESOLVED FIXED P2 Normal --- 1 mhahnenberg mhahnenberg webkit.review.bot oldest_to_newest 809671 0 mhahnenberg 2013-01-17 13:01:31 -0800 m_context is no longer weak, so there is now a lot of dead code in in JSValue.mm, and a wasted message send on every API call. In the head of just about every method in JSValue.mm we're doing: JSContext *context = [self context]; if (!context) return nil; This is getting a retained copy of the context, which is no longer necessary now m_context is no longer weak. We can just delete all these lines from all functions doing this, and where they were referring to the local variable 'context', instead we can just access m_context directly. 809681 1 mhahnenberg 2013-01-17 13:12:18 -0800 <rdar://problem/13035927> 809683 2 183254 mhahnenberg 2013-01-17 13:14:27 -0800 Created attachment 183254 Patch 809690 3 183254 mhahnenberg 2013-01-17 13:16:47 -0800 Comment on attachment 183254 Patch Need to make some modifications. 809697 4 mhahnenberg 2013-01-17 13:25:18 -0800 Since we're already going to be modifying most of JSValue.mm, we'll also do the following: (1) context @property is no longer weak – the context property is declared as: @property(readonly, weak) JSContext *context; This is really only informative (since we're not presently synthesizing the ivar), but it is now misleading. We should change it to: @property(readonly, retain) JSContext *context; (2) the JSContext ivar and accessor can be automatically generated. Since we're no longer doing anything special with m_context, we can just let the compiler handle the ivar for us. We'll delete: JSContext *m_context; and: - (JSContext *)context { return m_context; } and find&replace "m_context" to "_context" in JSValue.mm. 809702 5 183259 mhahnenberg 2013-01-17 13:29:33 -0800 Created attachment 183259 Patch 809707 6 183259 fpizlo 2013-01-17 13:32:35 -0800 Comment on attachment 183259 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=183259&action=review > Source/JavaScriptCore/ChangeLog:8 > + m_context is no longer weak, so there is now a lot of dead code in in JSValue.mm, and a wasted message send in in 810072 7 183259 webkit.review.bot 2013-01-17 18:35:11 -0800 Comment on attachment 183259 Patch Clearing flags on attachment: 183259 Committed r140086: <http://trac.webkit.org/changeset/140086> 810073 8 webkit.review.bot 2013-01-17 18:35:14 -0800 All reviewed patches have been landed.
