i just upgraded gems to 0.9.2

after restarting the server, all of the previous apps break. checking
the logs reveals this for every actions:

Are you using Ruby 1.8.6? There was a change that broke Rails…
namely, a change in the behavior of Digest::SHA1.new. I got this
error on line 566, I think, but I suspect it’s related.

If you upgrade your Rails gems to 1.2.3 it should be OK (if my
diagnosis is right).

In fact I’m virtually sure of it – the line # difference can be
explained by different AR versions.

Yes, or freeze your applications to Rails edge or 1.2.3. 1.8.6
definitely broke Rails as it stood at the 1.2.2 release.

I had the same problem, that’s what I did:
1: I deleted the directory of the relevant rails app on my hosts server
(of course backup any important stuff you don’t have offline)
2: via ssh I created a new fresh version on the host-server (you of
course need ssh access, but just ask your host)
3: I uploaded all relevant files/directories over the fresh rails app.
That was the whole “app” directory some stuff in the “public” directory,
namely stylesheets and images (and deleting index.html) database.yml,
the “db” directory, routes.db (if you use them) and set the environment
to production by uncommenting the line in environment.rb .
You probably have to upload other stuff depending on what you used and
changed.
I’m sure there is an easier way to achieve this, by only keeping the
files that’s needed but I couldn’t pinpoint all those files yet.
Hope that helps

did something change with the routing in the new version of rails?

after freezing rails to the app, nothing works that isn’t on the first
page.
