Rails - Mar 2008 - Safari 3.1 AJAX crashes not caused by getElementsByClassName

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

    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!

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...

Unfortunately I am in shared hosting, can''t change fast-cgi to mongrel 
and can''t hack request.rb.

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.

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

Dang! Spoke too soon

Freezing to the gems for Rails 2.0.2
Unpacked gem: 
''/home/familie2/registration/vendor/rails/activesupport-2.0.2''
ERROR:  While executing gem ... (Gem::Exception)
    Cannot load gem at 
[/home/familie2/.gems/cache/activerecord-2.0.2.gem] in 
/home/familie2/registration/vendor/rails

Do I need to clobber the cache somehow?
