This interface isn't scriptable and only on Gecko (not used into comm-central).
Makoto, could you describe specifically what should be done to deCOM nsILanguageAtomService? 

(The only thing I can think of is to make the interface functions return nsresult, but that seems to me only a marginal improvement, if any.)
The interface functions all return an nsresult outparam, mostly forwarded from nsresult return values from other function calls. I went through the implementations and discovered they all return either NS_OK or NS_ERROR_FAILURE. So just checking the returned pointer for null would do the trick.

I took a cue from DMO on deCOM and attempted to remove the interface in favour  of using the concrete class directly. I used NS_DEFINE_STATIC_CID_ACCESSOR for completeness sake, but I don't understand its purpose.

rm nsILanguageAtomService, outparamdel, devirtualise and minor clean-up

Review of attachment 625511 [details] [diff] [review]:

You don't understand "decom"  decom means that object doesn't inheritance from nsISupport.  (ex. bug 635170 for sample)  And we need modify nsLocaleConstructors.h for decom.

Also, if possible, this object can be singleton class. or all member variant and method can be static.

don't use rv for nsIAtom.  "rv" uses as nsresult.  (See

This patch employs reference counting for nsLanguageAtomService to avoid dangling pointer issues during XPCOM shutdown. If it is possible to do without reference counting, I'm all ears. :)

I happened to run across nsILanguageAtomService recently, and was going to do some cleanup; then found this bug already on file. Sorry it has languished without review for so long. Of course, in the meantime the patch has bit-rotted and no longer applies to trunk code. So I have rebased/updated the patch, and simplified a bit further (I don't think we need to refcount the nsLanguageAtomService at all, it's just a singleton that will live until shutdown). Let's see if we can actually get it landed this time...
