Partial test case for enumerable self-hosted functions
1.34 KB, text/plain
Details 
To reproduce, build with the attached patch, use the js shell, and run:

js> for (var p in Array.prototype) print(p)

With current sources, this prints "enumerable", the name of the self-hosted function provided by the patch.

Self-hosted functions, being built-in functions, generally must not be enumerable - see the last paragraph of ES 5.1, clause 15:
http://ecma-international.org/ecma-262/5.1/#sec-15

This regression was introduced somewhere between mozilla-central revisions a76c1f4c4112 (2012-10-17) and dd68409d7810 (2012-10-13).
The last date in the description should be 2012-11-13.
Blocks: 769872
This is probably caused by bug 807228, and should be fixed again once bug 791850 lands.
