[Buildbot-devel] ShellCommand on windows7 slave does nothing

[John Stile]

Migrating a slave from WinXp (32bit) to Win7 (64bit), I find my
ShellCommand returns immediately without any output, and program
finished with exit code 1.

My slave is started from cygwin (buildbot is installed in cygwin and
started from cygiwn).

twistd.log on master and slave show they are talking, and the slave log
shows the ShellCommand string was received.

I see no output, save the environment variables and the issued command.
I modified my command to run just pwd, but nothing is output.
I modified my command to touch a file, but no file is created.
So I don't think the command is executed on the slave.

How can I debug this?  
Is there a windows7 problem?
Any advice is very much appreciated.

slave Buildbot version: 0.7.6, Twisted version: 2.5.0
master Buildbot version: 0.7.9, Twisted version: 8.1.0

My master.cfg looks like this (removing extraneous stuff):
from os import system
from commands import getoutput
from buildbot.steps import source, shell
from buildbot.process import factory
from buildbot.process.properties import WithProperties
c = BuildmasterConfig = {}
c['slaves'] = [
  BuildSlave("buildxp2.mydomain.com", "foodles"),
  BuildSlave("buildwin3.mydomain.com", "foodles"),
]
c['slavePortnum'] = 9989
c['change_source'] = []
d = factory.BuildFactory()
d.addStep(
  shell.ShellCommand(
    command=[ "touch", 'foodles.txt'],
    description=["Building Win"],
    descriptionDone=["Built Win"]
  )
)
c['builders'] = [
{'name':'win_europa',
 'slavename':'buildwin3.mydomain.com',
 'builddir':'Europa_win',
 'factory':d },
]
