[Buildbot-devel] Noob master.cfg question....

[Shaun O'Shea]

Hi,
 
After years of writing my own automated build systems using various
flavours of shell scripts etc I'm looking try something 'off the shelf'.
Having investigated a number of options I like the look of buildbot
given that we build our stuff on numerous platforms with different
compilers etc (Sun sparc, Sun x86, Linux, AIX, Windoze....)

I have googled around and read as much as I could find before posting
this, if I've missed an obvious location for info then please pass it
on....
 
So far I have downloaded and installed:
 
Buildbot 0.7.6 
Twisted 2.5.0 
Python  2.5.1
 
I'm also a noob as far as python is concerned but it doesn't look too
scary :)
 
So I've been trying to edit the master.cfg to get a buildmaster going
with approximate basic config but with no success.....
 
Here's the output when I try to start buildbot:
<SNIP>
COPS-pubtools66% buildbot start `pwd`

2008/01/18 14:11 +0100 [-] The new config file is unusable, so I'll
ignore it.
2008/01/18 14:11 +0100 [-] I will keep using the previous config file
instead.
 
The buildmaster appears to have encountered an error in the master.cfg
config file during startup. It is probably running with an empty
configuration right now. Please inspect and fix master.cfg, then restart
the buildmaster.

COPS-pubtools68% buildbot --version
Buildbot version: 0.7.6
Twisted version: 2.5.0
COPS-pubtools69% python --version
Python 2.5.1

</SNIP>
 
Anybody got any ideas?

Here's my master.cfg without comments, I've put it together from reading
various web pages and looking at sample .cfg's etc...:

<SNIP>
c = BuildmasterConfig = {}


from buildbot.buildslave import BuildSlave 
c['slaves'] = [BuildSlave("linpc-script1", "32bitlnx86")]

c['slavePortnum'] = 9989

from buildbot.changes.pb import PBChangeSource 
c['change_source'] = PBChangeSource()


from buildbot.scheduler import Scheduler, Periodic 
periodic = Periodic("every_1_hours", ["lnx86-builder"], 60*60) 
c['schedulers'] = [periodic]

cvsroot =
":pserver:pubtools at cdsirl40:/projects/install_dub/CVS/repository"
cvsmodule = "cadencehelp"

from buildbot.process import factory
from buildbot.steps.source import CVS
from buildbot.steps.shell import Compile 
from buildbot.steps.python_twisted import Trial 
f = factory.BuildFactory() 
f.addStep(CVS(cvsroot=cvsroot, cvsmodule=cadencehelp, login="",
branch="branch1_1", mode="copy")) 
f.addStep(Compile(command=["echo TESTCOMPILE | mail osheas"]))

b1 = {'name': "lnx86-builder",
      'slavename': "linpc-script1",
      'builddir': "full",
      'factory': f,
      }
c['builders'] = [b1]

c['status'] = []

from buildbot.status import html
c['status'].append(html.WebStatus(http_port=8010))




c['projectName'] = "CadenceHelp"
c['projectURL'] =
"http://ecms.cadence.com/bin/view.cgi/CadenceHelp/WebHome/"


c['buildbotURL'] = "http://cops-ray2:8010/"
</SNIP>

I reckon if I can get past this basic first hurdle I should be able to
make some progress.
Any suggestions greatly appreciated!

Cheers,

~Shaun.
