Prior to squirrelfish it generated different results for every test file. Now the files are all identical 12/29/08 5:59 PM Oliver Hunt: The unification of the random number generation in r39337 made random number generation always start with the same seed in JSC. This is non-standard behaviour based on both our old behaviour and that of other browsers. <rdar://problem/6469185> 103765 1 zwarich 2008-12-29 21:11:49 -0800 What's a good fix for this problem? 103766 2 oliver 2008-12-29 21:23:52 -0800 Bad Niko, seeding random but then using rand() 103767 3 zwarich 2008-12-29 21:39:16 -0800 Fixed in r39507: http://trac.webkit.org/changeset/39507 103785 4 zimmermann 2008-12-30 05:10:52 -0800 Ouch, thanks a lot for fixing Cameron :-)
