[Buildbot-devel] Problem setting slave environment property

[sergio borghese]

Hi Everyone,

I'm facing a really weird issue on buildbot, setting the env property.
Strange thing is that I have some configuration where the env configuration
is working as expected.

The scenario that is showing that misbehavior is the following:

buildmaster v0.8.8 running on gentoo with python 2.7
buildlslave v.0.8.9 running on CentOs 5.10 with python 2.6

the slave has the following shell command:

qmake = ShellCommand(

command = ["qmake"],

warnOnWarnings = True,

haltOnFailure = True,

workdir = nr.iqac_platform_build_root,

name = "qmake",

env = nr.*centos510_64bit_env_dict* )


where *centos510_64bit_env_dict *is { 'PATH':
["/usr/local/Trolltech/Qt-4.8.5/bin", "${PATH}"] }


Problem is that the environment is not properly set and the shell command
fails.

>From the master log I can seen:

To me the above log means that the env is not set (as if the veriable has
not been set in the slave configuration) Of course I might be wrong, that's
why I'm asking for some advice.
As stated before, I already used the env configuration property with
another slave running on MacOSX (cannot retrieve the slave version as the
host is down right now)

Any idea of what I'm doing wrong ?
Do you think the slave version > master version can be an issue?
The slave has been installed using easy_install and that's the version
retrieved by the setuptools fro python 2.6

Best Regards
Sergio
