DRbConnError when using script/runner

Ruby Apps Ferret
1

I am running ferret (0.11.4) and acts_as_ferret (stable from svn) in a
rails 1.2.3 app in production using the DRb server. I recently upgraded
my configuration and the method with which I start and stop the server
no longer works: Here is the command I would like to use (and have used
in the past) to start the aaf server:

$ /Library/WebServer/rails/ccdb/current/script/runner -e production
/Library/WebServer/rails/ccdb/current/script/ferret_start
/opt/local/lib/ruby/1.8/drb/drb.rb:736:in `open’: druby://localhost:9090

  • #<Errno::ECONNREFUSED: Connection refused - connect(2)>
    (DRb::DRbConnError)
    from /opt/local/lib/ruby/1.8/drb/drb.rb:729:in each' from /opt/local/lib/ruby/1.8/drb/drb.rb:729:inopen’

    from /opt/local/lib/ruby/1.8/drb/drb.rb:1103:in with_friend' from /opt/local/lib/ruby/1.8/drb/drb.rb:1084:inmethod_missing’
    … 28 levels…
    from
    /Library/WebServer/rails/ccdb/current/script/…/config/…/vendor/rails/railties/lib/commands/runner.rb:39:in

    from /Library/WebServer/rails/ccdb/current/script/runner:3

Strangely the follwoing command works:

$ cd /Library/WebServer/rails/ccdb/current && RAILS_ENV=production
/Library/WebServer/rails/ccdb/current/script/ferret_start
Starting ferret DRb server…Done.

I would simply switch to that but I am on an Xserve and I’m using
launchd to start the aaf server on reboot. launchd does not seem to
like the command that works.

Anyone know why I would get a DRbConnError when using script/runner?

Thanks in advance,
Tom

Hi!

most probably this happens because with script/runner, your model
classes get loaded before the server gets a chance to tell them they
shouldn’t run in remote mode. Hence aaf tries to connect to the DRb
server, which of course is impossible since it hasn’t been started up
yet, resulting in the error you see.

Try to set the environment variable FERRET_USE_LOCAL_INDEX to ‘true’ in
your launch command:

$ FERRET_USE_LOCAL_INDEX=true
/Library/WebServer/rails/ccdb/current/script/runner -e production
/Library/WebServer/rails/ccdb/current/script/ferret_start

cheers,
Jens

Thanks for the quick reply. Unfortunately that did not work. Different
error however:

Any advice?

Again thanks for the assistance. I have a feeling this is related to
the server platform (OS X Server 10.4.10). Do people on Linux get these
kind of errors?

Hi!

I just committed a slight change to the ferret_start script which should
fix this.

Here’s the changeset:
http://projects.jkraemer.net/acts_as_ferret/changeset/252

You’ll still need the FERRET_USE_LOCAL_INDEX environment variable,
however.

Cheers,
Jens

FIXED! Works like a charm now. That really makes my week. Adding aaf
search was so simple and now that this minor inconvienence is fixed I’m
a happy programmer. Thanks for creating such a great tool.
