[Buildbot-devel] Python PATH problems?

[Ben Hearsum]

Hi,

I'm in the process of setting up buildbot 0.7.3 on some linux and windows
hosts. The buildmaster is hosted on a linux machine. There are 3 linux
slaves and 2 windows slaves. All of the Linux slaves work 100% fine but
I'm having issues with windows.

My build script checks out code from CVS and then proceeds to build the
tree. When a windows machine attempts to pull code from CVS the execvpe
fails:

Upon execvpe cvs ['cvs', '-d',
':pserver:anonymous at cvs-mirror.mozilla.org:/cvsroot', 'co',
'mozilla/client.mk'] in environment id 419141804:
Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/twisted/internet/process.py",
line 777, in __init__
    os.execvpe(command, args, environment)
  File "/tmp/python.340/usr/lib/python2.4/os.py", line 350, in execvpe
    _execvpe(file, args, env)
  File "/tmp/python.340/usr/lib/python2.4/os.py", line 379, in _execvpe
    func(fullname, *argrest)
OSError: [Errno 2] No such file or directory

The error message also shows me all of the environment variables. The PATH
is set as follows:
'PATH': 'C:\\Program Files\\Microsoft Visual Studio
8\\Common7\\IDE;C:\\Program Files\\Microsoft Visual Studio
8\\VC\\bin;C:\\Program Files\\Microsoft Platform SDK\\bin;C:\\Program
Files\\Microsoft Visual Studio 8\\VC;C:\\Program Files\\Microsoft Visual
Studio 8\\Common7\\Tools;C:\\Program Files\\Microsoft Visual Studio
8\\Common7\\Tools\\bin;C:\\proj\\vc8-moztools\\bin;C:\\cygwin\\bin;C:\\WINDOWS\\system32;'


'cvs' can be executed fine from any cygwin shell, from a windows cmd, and
from the command line python interpreter! If I use a full path to cvs.exe
it works without issue.

I have posted my master.cfg and a supporting file:

I realize that this may not be a buildbot problem but any input would be
appreciated.

Cheers.
