[users at bb.net] ForceScheduler trouble converting from 0.8.12 to 0.9.0

[Pierre Tardy]

Hi Falk,

Unfortunatly, getChoices do not work anymore with buildbot nine.

The configuration fo the forceschedulers is now purely static.

There is  a bug for that:
http://trac.buildbot.net/ticket/3351

I can see from another email on this list that you are interrested in
having a list of recently pushed tags.
I think this make sense, and buildbot_travis has some experimental
implementation for similar stuff.

I think the best option is for yout is to create a custom parameter which
would query the change api, and filter by category, and repository

for example this gives the list of pull requests of buildbot.
https://nine.buildbot.net/api/v2/changes?category=pull&project=buildbot/buildbot

There is no tag changes yet in this bot, as the github hook wasn't
configured to push tag events.

There is an example in the source code of a custom parameter.
https://github.com/buildbot/buildbot/tree/master/www/nestedexample
The use case is slightly more complex, but it should be easily simplifyable.
I understand however that this method is much more work thant the previous
getChoices method :-/

Hi,



I am currently in the process to convert an existing master.cfg from 0.8.12
to 0.9.0.

The guide “Upgrading to Nine” helped.



Now I am stuck at the point where the ChoiceStringParameters don’t work as
before.

The corresponding selection forms on the website are empty.

I could track the problem down, that the function “getChoices” is not
called any longer.



I post some code that worked with 0.8.12:



class GitChoiceParameter(ChoiceStringParameter):



    name = "gitchoice"



    def __init__(self,

                 name,

                 label,

                 repository, **kwargs):

        self.repository = repository

        log.msg("Initialized GitChoiceParameter for %s %s" % (name, label))

        ChoiceStringParameter.__init__(self, name=name, label=label,
**kwargs)



    def getChoices(self, master, scheduler, buildername):

        # This never gets called

        log.msg("GitChoiceParameter getChoices %s " % self.label)



master.cfg:

# As from the docu

codebase = util.CodebaseParameter(“”, “Repo”,
branch=GitChoiceParameter(name=’branch’, label=’Branch:’, repository=’…’))



Once I add choices=[‘A’, ‘B’, ‘C’]

util.CodebaseParameter( …., repository=’…’, choices=[‘A’, ‘B’, ‘C’])

I can see ‘A’, ‘B’ and ‘C’ on the website.

BUT my getChoices function is still not called at all.



Best regards,

Falk
