Open Stack

Hello,

I am wondering how ZUUL_NODE works and overall how the Jenkins Gearman
plugin handles Jenkins labels.

My setup has slaves used for continuous integration and some others for
a staging cluster.  I have Ubuntu Precise and Trusty nodes.

On my nodes I have applied labels such as:

 contint001:  contint, UbuntuPrecise
 contint002:  contint, UbuntuTrusty

 staging001: staging, UbuntuPrecise
 staging002: staging, UbuntuTrusty

In Jenkins job builder I thus AND labels to select where they will be
run. Ci jobs would have either:

 node: contint && UbuntuPrecise
Or:
 node: contint && UbuntuTrusty


Developers started willing to run python 3.4 jobs which is only
available on Trusty.  The JJB template is straightforward but is tied to
Precise:

- job-template:
    name: '{name}-tox-{toxenv}'
    node: contint && UbuntuPrecise
    builders:
     - tox:
         venv: '{toxenv}'

I would like to drop the UbuntuPrecise label and select it based on the
'toxenv' value. So:

- 'py27' would run on any slave having contint
- 'py34' would run on contint && UbuntuTrusty

I noticed the openstack_functions.py file which is used in Zuul to
finely tune ZUUL_NODE, and thus select a gearman label to run a job.

If the job name matches 'py34', I could set ZUUL_NODE=UbuntuTrusty, but
I am worried it is going to ignore the 'contint' label and thus run on
the staging cluster slaves labeled 'staging', UbuntuTrusty.


One way to fix it would be to copy paste '{name}-tox-{toxenv}' to a new
'{name}-tox-{toxenv}-trusty' which would have the UbuntuTrusty label.
But I would like to avoid repeating myself :-]

Am I missing something obvious?
