[Backgroundrb-devel] Mac, ActiveScaffold and BackgroundRB

Hi - backgroundrb is extremely useful, except in one case, Mac OS X with
ActiveScaffold. Even when I compile a test environment from Ruby source, I
still get an error on the Mac, but not on Linux.
I don''t know whether this is a backgroundrb problem, or an
ActiveScaffold
problem, or indeed a Mac problem... I''m sufficiently new to RoR that I
don''t
know where to start debugging and disentangling the ownerships of the
problem :)

Here''s the test case:

rails awcore
cd awcore
script/generate model Something foo:string bar:integer
git clone git://github.com/gnufied/backgroundrb.gitvendor/plugins/backgroundrb
rake backgroundrb:setup
script/generate worker listsorter
(edit listsorter to include a new methid "refresh" that runs
logger.info to
register the invocation)
(edit config/background.yml to include a periodic task)
script/backgroundrb start

This works just fine. Brilliantly so. One more step and it falls apart.

script/backgroundrb stop
git clone
git://github.com/activescaffold/active_scaffold.gitvendor/plugins/active_scaffold
&& rm -rf vendor/plugins/active_scaffold/.git
script/backgroundrb start

This will fail with either the Mac OS X Leaopard (10.5.5) Xcode 3.1 included
Ruby 1.8.6 or a fresh compilation of Ruby 1.8.7 (with the various gems). I
continues working on Debian (the only other test environment I tried - I
reckon that if it works there and fails on Mac, the Mac is implicated
somehow).

My gem list is:

actionmailer (2.1.2)
actionpack (2.1.2)
activerecord (2.1.2)
activeresource (2.1.2)
activesupport (2.1.2)
capistrano (2.5.2)
cgi_multipart_eof_fix (2.5.0)
chronic (0.2.3)
daemons (1.0.10)
fastthread (1.0.1)
gem_plugin (0.2.3)
highline (1.5.0)
hoe (1.8.2)
httpclient (2.1.2)
mongrel (1.1.5)
net-scp (1.0.1)
net-sftp (2.0.1)
net-ssh (2.0.4)
net-ssh-gateway (1.0.0)
packet (0.1.14)
rails (2.1.2)
rake (0.8.3)
RedCloth (4.1.0)
rubyforge (1.0.1)
soap4r (1.5.8)
sqlite3-ruby (1.2.4)

The error report is:

The worker is:

class ListsorterWorker < BackgrounDRb::MetaWorker
  set_worker_name :listsorter_worker
#  reload_on_schedule true
#  pool_size 1

  def create(args=nil)
    # this method is called, when worker is loaded for the first time
    logger.info ''listsorter initiated''
  end

  def refresh
    logger.info ''listsorterer refresh''
  end
end

The backgroundrb.yml is:

---
:backgroundrb:
  :port: 11006
  :ip: 0.0.0.0

:schedules:
  :listsorter_worker:
    :refresh:
      :trigger_args:
        :start: <%= Time.now + 5.seconds %>
        :repeat_interval: <%= 15.minutes %>
        :end: <%= Time.now + 1.month %>

I''m not sure how to further narrow the problem.

Obviously, removing script/backgroundrb results in the service working (with
the extra steps needed for an ActiveScaffold to work - but I *haven''t*
done
these, for this test - I was looking for a simple test case).

Suggestions for how to kill this problem, or what to look at next, are
welcome. I''d really like to develop on my Mac and then move it over to
the
production servers. Having to develop and test remotely is do-able, but ugly
slow.

Cheers, JeremyC.

[Backgroundrb-devel] Mac, ActiveScaffold and BackgroundRB

Following a suggestion by Samer Masry, I checked the Ruby versions. The
Linux system that worked was running Ruby 1.8.5. After updating to 1.8.7, it
fails in the same way as the macs (on 1.8.6 and 1.8.7).
I''m now tolerably convinced that the Ruby version is affecting the
failure... But now I don''t know whether to try asking on Ruby lists,
BackgroundRB list, or ActveScaffold list!

Cheers, JeremyC.
