Add the build status to build properties

[krf]

Scenario: We'd like to add the build status as a custom mail header.

For this to work (properly) we need a way to access the build status from 'WithProperties?' to pass it to MailNotifier?'s extraHeaders.

I think that this is something where your custom mail notifier would be querying data from the data API.

Which could be wrapped in a custom IRenderable.

Yep. That's what we did for now.

For other people interested in this, here's the code:

class BuildStatusRenderable(util.ComparableMixin):
    implements(interfaces.IRenderable)

    def getRenderingFor(self, props):
        build = props.getBuild()
        results = build.results
        return Results[results]

extraHeaders = {
    'X-Build-Status': BuildStatusRenderable()
}

Feel free to close this.

Thanks
