338614 - Add EXTENSIONS error module to nsError.h

Status: RESOLVED WONTFIX

(Core :: XPCOM, enhancement)

Description

[Alex Vincent [:WeirdAl]]

I as an extension would like to begin defining error messages for the console specific to my extension.  (In this case, the extension is XPath Generator, bug 319768.)  To do this, I'd need to reserve a spot under nsError.h for either my own extension (which is unreasonable) or for all extensions living in the mozilla.org tree.

I'm proposing we define a module for nsError.h, and host the error definitions and messages at extensions/extensions-errors.h.

In addition, it would probably be wise for a wiki page to exist at http://wiki.mozilla.org/XPCOM:Extensions_Errors

where extensions could reserve smaller blocks of error messages.

I don't think this is especially useful nowadays. Less XPCOM is better xpcom.
