Bug 1207245 - part 6 - rename nsRefPtr<T> to RefPtr<T>; r=ehsan; a=Tomcat The bulk of this commit was generated with a script, executed at the top level of a typical source code checkout. The only non-machine-generated part was modifying MFBT's moz.build to reflect the new naming.

Bug 1332172 - Remove XPC_MAP_WANT_*. r=mccr8. nsIXPCScriptable flags handling in xpc_map_end.h is a bit of a mess. - Half the flags relate to whether various functions are defined (PreCreate, GetProperty, etc). These are set using the XPC_MAP_WANT_* macros; for each one xpc_map_end.h inserts the corresponding flag using the preprocessor (see XPC_MAP_CLASSNAME::GetScriptableFlags()). - The other half of the flags relate to other things (IS_GLOBAL_OBJECT, DONT_REFLECT_INTERFACE_NAMES, etc). These are set using the XPC_MAP_FLAGS macro. Having two similar but different mechanisms to set the flags for a class is confusing. (Indeed, until recently we had some classes where a single flag was redundantly specified via both mechanisms.) Note also that the classes done in dom/base/nsIDOMClassInfo.h also specify all the flags in a single value, similar to how XPC_MAP_FLAGS works. This patch removes the XPC_MAP_WANT_* macros. All flags are now set via XPC_MAP_FLAGS. This is a significant simplification to xpc_map_end.h and all the places that use it. The downside of this change is that I had to change the flag constants from class constants (i.e. nsIXPCScriptable::FOO) to macros (i.e. NSIXPCSCRIPTABLE_FOO) because they need to be used in #if statements like this in xpc_map_end.h: #if !((XPC_MAP_FLAGS) & NSIXPCSCRIPTABLE_WANT_PRECREATE) and you can't use a '::'-qualified name inside a #if. I think this downside is outweighed by the simplification described above. Overall the patch removes 80 lines of code. --HG-- extra : rebase_source : 6d5c341d0deba8f1529d81c17bb8819e09620b05
