This is straightforward, with only two notable things. - `#include "nsXPIDLString.h" is replaced with `#include "nsString.h"` throughout, because all nsXPIDLString.h did was include nsString.h. The exception is for files which already include nsString.h, in which case the patch just removes the nsXPIDLString.h inclusion. - The patch removes the |xpidl_string| gtest, but improves the |voided| test to cover some of its ground, e.g. testing Adopt(nullptr). --HG-- extra : rebase_source : 452cc4a08046a1adb1a8099a7e85a1917de5add8

Implementations for a bunch of useful RDF utility routines. Many of
|
|
these will eventually be exported outside of RDF.DLL via the
|
|
nsIRDFService interface.
|
|
|
|
TO DO
|
|
|
|
1) Make this so that it doesn't permanently leak the RDF service
|
|
object.
|
|
|
|
2) Make container functions thread-safe. They currently don't ensure
|
|
that the RDF:nextVal property is maintained safely.
