[users at bb.net] Get previous step build result

[Hugh Sorby]

Thanks Roland for the pointer, I ended up with this



@defer.inlineCallbacks

def end_to_end_testing_succeeded(build_step):

    build_id = build_step.build.buildid

    master = build_step.build.master

    build_steps = yield master.data.get(("builds", build_id, 'steps'))

    for step in build_steps:

        if step['name'] == 'Trigger End-to-End Testing':

            return step['results'] == SUCCESS


    return False


And applied it like this:

doStepIf=end_to_end_testing_succeeded,

Seems to work.

I'm using Buildbot 3.5.0 and I would like to know if the previous step failed or succeeded.
I have tried to use the doStepIf method to figure out the previous steps status, but I haven't been able to make this work.

Is it possible to do this with 3.5.0?

Hey,

sorry can't give you a dry cut answer. I do have a few pointers for when we needed to fetch a previous build.

Have a look at: `getPreviousBuild` from:
https://github.com/buildbot/buildbot/blob/master/master/buildbot/reporters/utils.py<https://github.com/buildbot/buildbot/blob/master/master/buildbot/reporters/utils.py>

Over at scummvm we use a custom reporter which compares the current build to the last one on master branch.

Here is our vendorized `getPreviousBuild`:
https://github.com/scummvm/scummvm-sites/blob/director-buildbot/director/vendor/reporter_utils.py<https://github.com/scummvm/scummvm-sites/blob/director-buildbot/director/vendor/reporter_utils.py>

Note: we're on 2.8.4

Regards,

Roland


Many thanks for any suggestions/pointers.
