Edge: Session Cookie Fix Causing Issues for Legacy App

Rails
1

I love the idea of the cookie fix for session storage. But… I’ve gone
round
and round to get edge working with a legacy app and wonder if anyone has
any
pointers. Here’s what’s happening. I fresh-installed:

rails foo
cd foo
rake rails:freeze:edge
rake rails:update
– add secret to environment.rb –

All good, passing tests, no problems with session cookies. Then I cp -r
my
application tree over, preserving environment.rb. After that copy, I
get:

ArgumentError (`name’ required):

/vendor/rails/actionpack/lib/action_controller/cgi_ext/cookie_performance_fix.rb:44:in
`initialize’

/vendor/rails/actionpack/lib/action_controller/session/cookie_store.rb:129:in
`new’

/vendor/rails/actionpack/lib/action_controller/session/cookie_store.rb:129:in
`write_cookie’

/vendor/rails/actionpack/lib/action_controller/session/cookie_store.rb:87:in
close' /opt/local/lib/ruby/1.8/cgi/session.rb:324:in close’
/vendor/rails/actionpack/lib/action_controller/base.rb:1209:in
`close_session’

I’ve verified that the cookie name is coming in as empty and the
ArgumentError is being raised for a reason. I just don’t see why that
would
be.

Does anyone have any thoughts about this?

Here’s more about the environment:

You need to provide :session_key and :secret session options in
environment.rb. It’s generated for you in new apps.
config.action_controller.session = { :session_key =>
‘_myapp_session’, :secret => ‘ssh! be quiet’ }
Note that it’s moving from application.rb to the environment.

I added an explicit ArgumentError rather than letting it fall through
to an empty cookie name.

Thanks so much. Cookie-based sessions should be an amazing help.

Here’s a follow-up question. Are session_id values guaranteed to
remain the same between calls? I know you aren’t relying on the
session_id to identify the information anymore.

The session cookie now contains data rather than an id.

I only ask because I’ve been looking at Simple Captcha, which uses
the session_id as part of the hash that identifies the captcha answer
in pstore. Oddly, the session_id works perfectly with this when using
AR session store, but not with the new cookie-based session store.

You can store an id in the session data instead.

Rick O.'s CSRF-prevention plugin takes this approach.
