78024 - unhelpful "deprecated getter usage" warning

Status: RESOLVED INVALID

(Core :: JavaScript Engine, defect)

Description

[Jesse Ruderman]

When I load this testcase, I get a "deprecated getter usage" warning on the 
javascript console, but no indication of what the correct syntax is.  The 
message should say what the correct syntax is or give a URL explaining what the 
correct syntax is.

I tried looking at Mozilla's source code to figure out what was generating the 
message, but instead of finding the string "deprecated getter usage", all I 
found was http://lxr.mozilla.org/seamonkey/source/js/src/js.msg#233 :
MSG_DEF(JSMSG_DEPRECATED_USAGE, 158, 1, JSEXN_REFERENCEERR, "deprecated {0} 
usage").

This is a core jsengine issue. Reassigning.
Can anyone point out a document explaining the supported syntax?

cc'ing Brendan, Patrick, Rob for their opinions on this - and in case
they know any specific doc or URL that explains this issue correctly.

I found a way to define a getter in Mozilla without producing a warning by 
searching Google for "HTMLElement.prototype".

produces a warning:
HTMLElement.prototype.ih getter = function (str) { return "*" + this.innerHTML 
+ "*"; }

doesn't produce a warning:
HTMLElement.prototype.__defineGetter__("ih", function () { return "*" + 
this.innerHTML + "*"; } )

Are either of these methods standard, or are they both specific to Mozilla?

http://www.mozilla.org/js/js15.html has pointers, but the google (originally,
deja) links are dangling, sort of.  Rob, endico: do we have more such on the
www.mozilla.org site?

I think the thread discussing this getter/setter change is now at

Support for the "x getter = function() {}" syntax was removed in bug 517580, so let's close this.
