[Buildbot-devel] New User & odd/different source requirements

[Gwyn Evans]

Hi,
    I've made some progress, but I'm still having some problems at a
early stage...

  Basically, I was having some issues with the initial command step
not working[see at end of mail], so I've added a few earlier steps,
but the slave process appears to only do the 1st step...

  My master.cfg file is:-

-------------
#! /usr/bin/python

from buildbot.process.base import ConfigurableBuildFactory
from buildbot.process import step

steps = [
         (step.ShellCommand, {'workdir': '.',
                              'command': ['pwd']}),
         (step.ShellCommand, {'workdir': '.',
                              'command': ['printenv']}),
         (step.ShellCommand, {'workdir': '.',
                              'command': ['date']}),
         (step.ShellCommand, {'workdir': '.',
                              'command': ['cleartool', 'setview', 'gwyeva1']}),
         (step.ShellCommand, {'workdir': '/vobs/transport',
                              'command': ['acrossmake', '-f',
'MakefileTservInv', 'dbg']}),
        ]

c = {}

c['bots'] = [["bot-TServInv", "TServInv"]]

c['sources'] = []
c['builders'] = []

b1 = {'name': "TServInv",
      'slavename': "bot-TServInv",
      'builddir': "/home/gwyeva1/BuildBot/Bot-TServInv",
      'factory': ConfigurableBuildFactory(steps),
      }
c['builders'].append(b1)

c['slavePortnum'] = 18007
c['webPortnum'] = 18080
c['debugPassword'] = "asdf"

BuildmasterConfig = c
--------

  I built the slave tap with --master localhost:18007 and am able to
run the master & slave.  When I access the web-page, I can see when
the slave connects.  However, if I ping the slave, the web log shows
"pinging" then "ping failed", although the slave's log doesn't show
anything odd:-
2004/09/13 13:39 MEST [Broker,client] message from master: attached
2004/09/13 13:39 MEST [Broker,client] setBuilderList [('TServInv',
'/home/gwyeva1/BuildBot/Bot-TServInv')]
2004/09/13 13:39 MEST [Broker,client] builder 'TServInv' message from
master: attached
2004/09/13 13:39 MEST [Broker,client] builder 'TServInv' message from
master: ping

  If I force a build, the web page shows "running 'pwd'" with the
'log' link there showing
command '['pwd']' in dir /home/gwyeva1/BuildBot/Bot-TServInv/. [0 96342]
/home/gwyeva1/BuildBot/Bot-TServInv

and the slaves's log showing :-
2004/09/13 13:46 MEST [Broker,client] startBuild
2004/09/13 13:46 MEST [Broker,client]  startCommand:shell [id 0 96342]
2004/09/13 13:46 MEST [Broker,client]   command '['pwd']' in dir
/home/gwyeva1/BuildBot/Bot-TServInv/. [0 96342]

but nothing more happens 'till the command times out and it's killed
"command timed out: 1200 seconds without output, killing pid NNNN"

  Any ideas or anything look odd?

-------
  If I delete the pwd, printenv, date steps, then try, I get the following:-

2004/09/13 13:56 MEST [Broker,client] startBuild
2004/09/13 13:56 MEST [Broker,client]  startCommand:shell [id 0 317672]
2004/09/13 13:56 MEST [Broker,client]   command '['cleartool',
'setview', 'gwyeva1']' in dir /home/gwyeva1/BuildBot/Bot-TServInv/. [0
317672]

  I was originally trying to seperate the cleartool from the steps to
see where the error was, but it didn't clarify anything for me, so
I've put them both in here!

  Any help gratefully received!
