Cruisecontrolrb users - Aug 2007 - Question on triggers and overall config

Hi there,

I have been looking in to CruiseControl and have two quick questions  
that I was hoping you could answer for me.

First of all, is the "trigger_by" supported yet, or would I need to  
just get the trunk version of cruise control for that?

The second question is about the config.rb. I understand there is a  
[cruise]/config/site_config.rb.example which gets used for each  
project. But if I have multiple projects, is there a "main" config.rb
somewhere? ie one config.rb that applies to *all* my projects, which  
individual project config.rb''s override?

(Just thought of a third question, albeit a small one: is there any  
limit on the number of projects that can run on one cruisecontrol  
server? I''m thinking about having about 50 projects....)

/Cheers,
Jelte

it''s in trunk but we should be releasing it soon.  nevertheless, feel
free
to grab the trunk

site_config actually applies to the server, not the project, but I
don''t
think it''s what you''re looking for.

you''re thinking about cruise_config.rb in each project directory. there
is
no shared config, but there doesn''t really have to be.  because
it''s ruby,
just add a

  require File.dirname(__FILE__) + "/../shared_cruise_config"

at the top of every one of your cruise_config.rb''s and you can put
shared
code in this new file, have another project settings block in there or
whatever

there is no limit,  however,  keep in mind that unlike java cruise, we
don''t
serialize builds.  there is a separate process fired up for every project.
so if your builds are long and cpu intensive and they happen fairly often,
you could be killing your machine.  and, even if that is not the case, each
builder currently takes up ~40-80 M of memory (it''s a rails thing) so
your
machine could limit you there.

Hmm... For some reason, the Reply button in for cruisecontrolrb-users
sends the reply to the original author, not to the list...

No, not yet. It''s on the trunk (and at the time of this writing has a
rather severe bug in it).

site_config.rb is a system-wide configuration. Project configuration
file is called cruise_config.rb. There isn''t anything central (other
than the hard-coded defaults). But you can create a
default_cruise_config.rb somewhere and require it from
cruise_config.rb of every project.

Never tried. The dashboard UI is designed to have 5-6 project panes
visible on the screen (although that can be easily changed), and I''d
also be concerned about overstressing the CI server. You''d certainly
have to run builds remotely (over SSH), and tweak the builder
configurations to reduce the amount of Subversion polling.

Actually, if I had to organize 50 builds under the same CI server
today, I''d be looking at CruiseControl the Original, rather than
CC.rb. ThoughtWorks is building a product out of it (called Cruise
Control Enterprise), so the latest release had a huge facelift and a
bunch of new features aimed exactly at big, complex CI situations.
