Hi all, I’ve been having a lot of trouble with Rails Errors for over I week, and I finally realized that they are caused by Safari 3.1, since everything works fine with FireFox… Pretty much every AJAX request makes the fcgi process crash… Moreover, I do _not_ use getElementsByClassName (which is known to be the cause of many problems), rails is up to date, and so is Prototype (1.6.0.1). Here is what the log says: /!\ FAILSAFE /!\ Thu Mar 27 13:47:50 +0100 2008 Status: 500 Internal Server Error can’t modify frozen string /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action\_controller/request.rb:462:in `gsub!' /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action_controller/request.rb:462:in`clean\_up\_ajax\_request\_body!’ /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action\_controller/request.rb:380:in `parse_formatted_request_parameters' /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action_controller/cgi_process.rb:78:in`request\_parameters’ /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action\_controller/request.rb:287:in `parameters' /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action_controller/request.rb:22:in`request\_method’ /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action\_controller/request.rb:35:in `method' /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action_controller/routing.rb:1483:in`extract\_request\_environment’ /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action\_controller/routing.rb:1424:in `recognize' /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action_controller/dispatcher.rb:170:in`handle\_request’ /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action\_controller/dispatcher.rb:115:in `dispatch' /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action_controller/dispatcher.rb:126:in`dispatch\_cgi’ /hsphere/local/home/cukch/rails/vendor/rails/actionpack/lib/action\_controller/dispatcher.rb:9:in `dispatch’ dispatch.cgi:10 I have no idea what this is caused by. The solution that was recommended is switching to Mongrel, and of course I would do it if I could… But I am on a shared host, so it is not possible… Does anyone has any idea how to solve this? I have tried for over a week, and nothing helps. I tried switching from fastcgi to plain old cgi, but the bugs remain the same (but plain old cgi is indeed used, for the request take a lot longer). Thank you very much if you can help! Nauhaie ---

I tried replacing vendor/rails/actionpack/lib/action\_controller/request.rb:462 * * * ## def clean\_up\_ajax\_request\_body!(body) body.chop! if body[-1] == 0 body.gsub!(/&\_=$/, ‘’) end BY * * * ## def clean\_up\_ajax\_request\_body!(body) unless body.frozen? body.chop! if body[-1] == 0 body.gsub!(/&\_=$/, ‘’) end end I don’t know if this might cause other kinds of problems, but at least, it doesn’t crash anymore… ---

Looks like I’m snookered until Safari/Fast-CGI/ or rails patches the bug. Can anyone think of any other way to work around this? It basically rules out AJAX from RoR for me which is a major blow! ---

You can if you freeze rails into your vendor/rails . IIRC this here is to work around a bug in some versions of safari where extra stuff would get appended to the end of ajax requests. Fred ---

Thanks Fred, So I’m guessing this means cp’ing from the /usr/lib/ tree through to either my own project or my own gems path. Is this a manual process is there some rails scripted way to freeze? Also - if I set my GEMS path correctly, can I move only the relevant files across? ---

There’s a rake task: rake rails:freeze:gems It’s an all or nothing thing, you can’t just freeze some gems or some files Fred
