+== Diagnostic mode
+
+Initially, you may find that a few files don't reload automatically. This is because they are being loaded during Spork startup. To identify which project files are being pre-loaded, and why, run:
+
+ spork --diagnose
+ (or spork -d, for short)
+
+It will output a lot of stuff. At the top you'll find a summary of all project files loaded. Down below, the stack trace for each file (how it got loaded). Spork hooks into Rails and does some magic (TM) to prevent ApplicationController observers, etc from pre-loading. Similar hooks for other ruby frameworks may come as support demands.

+Cucumber --drb support for spork is not official yet (but it works). It's the hottest sauce boiling on the world wide web right now. If you can't wait to try it, head on over to Cucumber core-team member Ben Mabey's drb branch and build your own cucumber gem:

== Some potential issues and ways to overcome them:
-=== ActiveRecord reports "connection has gone away" for the first few specs
+=== Database connections don't work inside of Spork
-Not sure why this happens, but if you simply add a line to re-establish your database connection on each line as follows, the problem goes away:
+If you're using ActiveRecord and Rails, Spork will automatically reconnect to the database. However, if you're not using ActiveRecord, or if you're doing some tricky stuff with connections, you'll have to make sure your connections get re-established on each run. In your spec/spec_helper.rb file:
Spork.each_run do
- ActiveRecord::Base.establish_connection # make sure that the db connection is ready.
+ # Do your connection re-establishing here
end

On one of our projects, many of us using TextMate with spork, only one developer got this error message while the rest of us ran just fine. I don't know exactly why it happened, but requiring the textmate formatter in the prefork block made it go away, like this:
