I just had an exciting afternoon-before-thanksgiving...I read all the goodness at: http://weblog.rubyonrails.org/2010/11/15/rails-3-0-3-faster-active-record-plus-plenty-of-fixes
...about better perf and low-risk changes with Rails 3.0.3, so I did a local upgrade from 3.0.1, ran some tests, everything seemed fine, pushed to staging, ditto, pushed to prod, ditto...went out to do some errands. And then got a crash alert: "2010-11-24T12:35:55-08:00 app[worker.1]: Could not find columnize-0.3.1 in any of the sources" boom! Rushed home, rolled back to 3.0.1... I'm still not sure exactly what happened - trying to diagnose now. But clearly some funkiness w/ dependency management btwn versions, as Rails 3.0.3 doesn't seem to install columnize (or linecache-0.43, possibly more) whereas they do get installed when Rails = 3.0.1. If anyone else has thoughts, please jump in. But, at the very least, consider this a public service announcement that the 3.0.1 -> 3.0.3 upgrade doesn't appear to be vanilla. -- You received this message because you are subscribed to the Google Groups "Heroku" group.
