Zuul can only apply one parameter function. Prevent us from injecting both php55 and extension dependencies
Closed, ResolvedPublic

Description is a simple test, merely meant to highlight the issue happening and reported on T125495.

Zuul can only invoke ONE parameter function for a job and the job would need two:

  • set PHP_BIN to switch to PHP5

The root cause is CI config change done as part of T119675: Adjust CI for PHP5.5 support.

+  - name: ^.*php55.*$
+    parameter-function: set_php_bin

Since it matches mwext-testextension-php55, that overrides the dependency injector :-/

Seems like we will need a single parameter function to be applied on all jobs and port the job regex to the parameter function which will then invoke other functions as needed. Something like:

 - name: ^.*$
   parameter-function: 'set_parameters'

And our custom set_parameters method would looks like:

import re

def set_parameters(item, job, params):
    if 'php55' in
        params['PHP_BIN'] = 'php5'

    if re.match( /^mwext-(testextension|qunit|mw-selenium)/,
        params = set_ext_dependencies(item, job params)

def set_ext_dependencies(item, job, params):
    # currently existing function

So this way we have all jobs being applied set_parameters and instead of dealing with job filter in the layout file, we deal with them in the python file.

Not much idea how to write an integration test that will cover that though. The parameter function is being called in zuul/launcher/ by Gearman.updateBuildParams. Unit tests for a new set_parameters() function would probably be sufficient.

Implemented. I'll file a follow-up for writing tests for set_parameters.
