Prototype Upgrade for Safari
Category: Prototype
Previous versions of Prototype could trigger bugs in Safari’s regular expression engine when updating elements with HTML containing <script> tags or when using JSON functionality with built-in security checks. These regular expression engine bugs affect Safari versions 1.3 through 2.0.4, but not Safari 3 beta or the WebKit nightlies. We’ve managed to code around them to prevent either browser crashing while maintaining the full API, keeping the performance top-notch and assuring backwards-compatibility.

Nice post.
There is an obscure but nasty bug in Safari 3.0.1 beta for Windows involving replace() callback functions when your data contains dollar signs (“$”). If this is not fixed by final release, it’s something developers should be aware of. Reproduction code can be found in this comment on my blog: http://blog.stevenlevithan.com/javascript/commafy-numbers/#comment-104
Compressed versions of this release and the previous major releases are up at their usual location.

Steven,
Has that bug been reported to Apple ?

I’ve entered a ticket here: http://bugs.webkit.org/show_bug.cgi?id=14244
Steve: thanks for the link. Note that as the regexps we modified in Prototype don’t rely on replace callbacks, we should be safe regarding the bug you mention.
