GitHubCommentPush

.. py:currentmodule:: buildbot.plugins.reporters


from buildbot.plugins import reporters, util

context = Interpolate("bb/%(prop:buildername)s")
c['services'].append(reporters.GitHubCommentPush(token='githubAPIToken', context=context))

:class:`GitHubCommentPush` publishes a comment on a GitHub PR using GitHub Review Comments API.

It requires txrequests package to allow interaction with GitHub REST API.

It requires a GitHub API token in order to operate. By default, the reporter will only comment at the end of a build unless a custom build report generator is supplied.

You can create a token from your own GitHub - Profile - Applications - Register new application or use an external tool to generate one.

.. py:class:: GitHubCommentPush(token, context=None, generators=None, baseURL=None, verbose=False)

    :param string token: token used for authentication. (can be a :ref:`Secret`)
    :type context: renderable string
    :param context: Passed to GitHub to differentiate between statuses.
        A static string can be passed or :class:`Interpolate` for dynamic substitution.
        The default context is ``buildbot/%(prop:buildername)s``.
    :type generators: list of IReportGenerator instances
    :param generators: A list of report generators that will be used to generate reports to be sent by this reporter.
        Currently the reporter will consider only the report generated by the first generator.
    :param string baseURL: specify the github api endpoint if you work with GitHub Enterprise
    :param boolean verbose: if True, logs a message for each successful status push

Here's a complete example of posting build results as a github comment:

@util.renderer
@defer.inlineCallbacks
def getresults(props):
    all_logs=[]
    master = props.master
    steps = yield props.master.data.get(
        ('builders', props.getProperty('buildername'), 'builds',
        props.getProperty('buildnumber'), 'steps'))
    for step in steps:
        if step['results'] == util.Results.index('failure'):
            logs = yield master.data.get(("steps", step['stepid'], 'logs'))
            for l in logs:
                all_logs.append('Step : {0} Result : {1}'.format(
                                    step['name'], util.Results[step['results']]))
                all_logs.append('```')
                l['stepname'] = step['name']
                l['content'] = yield master.data.get(("logs", l['logid'], 'contents'))
                step_logs = l['content']['content'].split('\n')
                include = False
                for i, sl in enumerate(step_logs):
                    all_logs.append(sl[1:])
                all_logs.append('```')
    return '\n'.join(all_logs)

generator = BuildStatusGenerator(message_formatter=MessageFormatterRenderable(getresults))
c['services'].append(GitHubCommentPush(token='githubAPIToken', generators=[generator]))
