Freeze nsIArray. According to http://www.mozilla.org/projects/embedding/HowToFreeze.html, we should have only one interface per IDL file. So this needs to be split into nsIArray.idl and nsIMutableArray.

This separates nsIMutableArray into its own IDL; moves the comptr-helpers to the glue; removes the NS_NewArray internal methods which are either poorly used or easy to replace using createinstance; fixes up treewide #includes and usage of NS_NewArray.

I see several other cases where do_CreateInstance failure is treated as an OOM condition. >Index: mailnews/base/src/nsMsgFolderDataSource.cpp > nsresult rv; > > nsCOMPtr<nsIMsgFolder> folder(do_QueryInterface(source, &rv)); > if (NS_FAILED(rv)) return rv; > >- nsCOMPtr<nsIMutableArray> cmds; >- NS_NewArray(getter_AddRefs(cmds)); >+ nsCOMPtr<nsIMutableArray> cmds = >+ do_CreateInstance(NS_ARRAY_CONTRACTID); > if (!cmds) return rv; This seems to return a success code if it cannot instantiate the array.

Fixed on trunk, with a couple additional platform- or configuration-specific bustage fixes.

This checkin broke XULRunner on Windows (at least). I know our tinderbox (solaria) has been busted for a while but you can see that the reason for the bustage switched right after this was checked in. From http://tinderbox.mozilla.org/showlog.cgi?log=XULRunner/1144862700.16448.gz - c:/builds/tinderbox/XR-Trunk/WINNT_5.2_Depend/mozilla/toolkit/library/dlldeps.cpp(61) : fatal error C1083: Cannot open include file: 'nsArray.h': No such file or directory I'm also seeing this on my machine. P.S. What's the deal with solaria being busted for so long? Is that a cairo thing?

(In reply to comment #4) > This checkin broke XULRunner on Windows (at least). bsmedberg patched the dlldeps.cpp file that was broken. http://tinderbox.mozilla.org/bonsai/cvsview2.cgi?diff_mode=context&whitespace_mode=show&subdir=mozilla/xpcom/build&command=DIFF_FRAMESET&file=dlldeps.cpp&rev1=1.147&rev2=1.148&root=/cvsroot

I believe this checkin also broke the spatial navigation extension, please see bug 333873.
