Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b5) Gecko/20050923 Firefox/1.4 Firefox gives an "unterminated character class" error on the regular expression /[/]/. Safari and Opera 8.5 accept it. I noticed this because a regular expression containing [/] appears in http://msdn.microsoft.com/workshop/code/browdata.js, which was mentioned in bug 309695 comment 9.
->all/all. This is technically invalid. <http://bclary.com/2004/11/07/ecma-262#a-7.8.5>. I have some raw data on top sites I can mine for how common this is in the wild.

This is entirely contrary to ECMA-262 Edition 3, and to its regexp progenitor, Perl. However, mrbkap expressed sympathy, however fleeting under my withering counterattack ;-). He wins this no-prize. I'm quite interested in bclary's top site spidering results. /be

I've been running scans of the top 69 sites 1 level deep (usually ~100 pages per site) and haven't seen an instance of this error. This doesn't imply that the error is rare. It has been a reoccuring issue over the years, especially on MS sites. I could run a 2 level scan if you think it would be worth it, but it would take a few days.
I think if we want this, we want it for Firefox 1.5.

Need a fix this week if this is going to make it.

we're not going to hold the release for this but if it comes to us with full reviews and it's low risk, we can talk.

Comment on attachment 197590 [details] [diff] [review] Allow / in char classes Yeah, this is safe. The only way to close a character class is with an unescaped ], and you can't nest character classes, so a boolean suffices. /be
Fix checked into trunk.

Comment on attachment 197590 [details] [diff] [review] Allow / in char classes This fixes a highly dup'ed IE compatibility bug. It's an extension to ECMA syntax that's allowed by Section 16. I'm approving it so that we can get it into 1.8b5 / Firefox 1.5b2. /be
Don't forget to set fixed1.8 when this lands on the branch tonight. /be
