274137 - xpidl should error if two interfaces have the same uuid

Status: RESOLVED EXPIRED

(Core :: XPCOM, defect)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; chrome://navigator/locale/navigator.properties; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; chrome://navigator/locale/navigator.properties; rv:1.7.5) Gecko/20041107 Firefox/1.0

I created a simoIList.idl file which is a base class for my list types.
Then I created a subclass simoIPersonList.idl 

[scriptable, uuid(7d7f9d13-11f3-4ec4-9ee8-63bd1df4f950)]
interface simoIList{};

and without being careful I copied the same uuid

[scriptable, uuid(7d7f9d13-11f3-4ec4-9ee8-63bd1df4f950)]
interface simoIPersonList : simoIList{};

this gave no errors or warnings from xpidl when invoked in the following way:

xpidl -w -v -e simoIPerson.xpt -m typelib -I/home/taf2/simo2/idl
-I$(MOZDIST)/idl simoIPerson.idl

Also, xpcom crashes in js when a simoIPersonList is accessed via 

var plist = Components.classes["contractid"].createInstance();

In latest trunk builds xpcom crashing seems to be fixed.  There still is no good
way for a xul developer to detect whether or not a duplicate uuid used in more
then one interface file.  Although, I would say this is out of the scope of both
xpcom and xpidl... a likely canidate for a xpcom centric debugger perhaps...
