Rails - May 2010 - Flash not deleting with Redis/Memcache store

I''m a recent convert to Rails and I''m working on a new project
using Rails 2.3 (I''ll probably upgrade at some point when Rails 3 is in
production and had a chance to bake the .0 bugs out). I''m going to use
Redis anyway for caching important data, so I thought I''d use the
redis-store:

http://github.com/jodosha/redis-store

But it appears the flash messages aren''t going away when
they''re supposed to as discussed in this issue, which I
haven''t gotten a response on yet:

http://github.com/jodosha/redis-store/issues#issue/3

The gist is ActionController::Flash::FlashHash#sweep isn''t properly
detecting that a flash has been used when using either the Memcache or Redis
store for sessions.

So how do I delete them manually? I thought about just editing the FlashHash
class and forcing it to delete any flash keys without checking the @used stuff.
That would for sure delete the key, but I don''t know enough about Rails
internals to say whether that will have unintended side effects.

Any advice on what I need to do here?

Thanks!

Hi,
I''ve fixed this issue in 0.3.8 by replacing the old implementation,
borrowed from rack.
Just config the gem:
# config/environment.rb
config.gem "redis-store"

then configure as session store:
# config/initializers/session_store.rb
ActionController::Base.session_store = :redis_session_store
