There is a collision between enum values for the different dispatchers. Generated code had both: > // InspectorProtocolObjects.h > > namespace Timeline { > enum class EventType { > ... > WebSocketDestroy = 133, > }; > } > > // InspectorFrontendDispatchers.h > > class InspectorDebuggerFrontendDispatcher { > public: > ... > enum class Reason { > Exception = 133, > }; > } We need to ensure that the values we generate are unique across all enums in all domains, not just the domains being generated for that particular dispatcher. 1045945 1 joepeck 2014-11-03 18:40:58 -0800 I have a fix, I need to make a test. 1045946 2 webkit-bug-importer 2014-11-03 18:41:11 -0800 <rdar://problem/18862317> 1045953 3 240899 joepeck 2014-11-03 18:54:29 -0800 Created attachment 240899 [PATCH] Proposed Fix Before the patch you can see the collision. > FAIL: enum-values.json-result > --- JavaScriptCore/inspector/scripts/tests/expected/enum-values.json-result 2014-11-03 18:50:12.000000000 -0800 > +++ /var/folders/_b/scj8wvc516g_708gsbsfwq5w0000gn/T/tmpg_18v0/enum-values.json-result 2014-11-03 18:50:33.000000000 -0800 > @@ -159,9 +159,9 @@ > // Named after parameter 'returnValue' while generating command/event commandWithEnumReturnValue. > enum class ReturnValue { > Shared = 0, > - Cyan = 1, > - Magenta = 2, > - Yellow = 3, > + Cyan = 6, > + Magenta = 7, > + Yellow = 8, > }; // enum class ReturnValue > virtual void commandWithEnumReturnValue(ErrorString&, InspectorCommandDomainBackendDispatcherHandler::ReturnValue* out_returnValue) = 0; > protected: > @@ -343,8 +343,8 @@ > // Named after parameter 'parameter' while generating command/event eventWithEnumParameter. > enum class Parameter { > Shared = 0, > - Black = 1, > - White = 2, > + Black = 4, > + White = 5, > }; // enum class Parameter > void eventWithEnumParameter(Parameter parameter); > private: 1045954 4 commit-queue 2014-11-03 18:57:18 -0800 This patch modifies the inspector protocol generator.
