relvalconsumer is a fedmsg consumer for creating Fedora release validation test events. It replaces the old relval nightly --if-needed sub-command, which was expected to be run nightly as a cron job. Like the old system, each time a compose appears, it runs various checks to decide whether it should create an event for the compose. It creates events for both nightly composes and 'candidate' composes.

It should create a first nightly for the next release shortly after a release goes out. From then until the release, it will create new nightly events periodically. It will never create a nightly event fewer than three days after the current event. Between three and fourteen days after the current event, it will create a new event if certain packages have changed (these are defined in the code). After fourteen days it will create an event as soon as a nightly compose appears. It will create events for all candidate composes as soon as they appear.

It should never create an event for a given release from a Rawhide compose after that release branches, because at that point wikitcms will decide that any notional event for a Rawhide compose would be for the release two after the current stable release, and this script will create events only for the release one after the current stable release.

Note that in production mode the consumer is configured to create events in the production wiki and send announcement emails to the test@ mailing list. So, really, only one person should ever have it running in production mode, and that's probably me. Please don't run it in production mode unless you're taking over my job or something.

The code was written with Python 3 in mind, but it turns out that verification of fedmsg message signatures does not currently work in Python 3, so it should be run under Python 2 for now.


Python libraries:


Install the required external Python libraries, then use setuptools to install, e.g.:

    python install

Test and production modes

Two consumers are provided, a 'test' and a 'production' consumer. For 'test':

  • The consumer listens for dev (not prod) messages
  • The consumer does not validate message signatures
  • The consumer creates events on the staging wiki (not production wiki)
  • The announcement email is logged rather than being mailed out

In this mode it is fairly safe to play around with the consumer, and you can use a tool like fedmsg-dg-replay to trigger event creation by replaying a relevant fedmsg (which will show up with a dev topic rather than prod).

For 'production':

  • The consumer listens for prod (not dev) messages
  • The consumer validates message signatures
  • The consumer creates events on the production wiki
  • The consumer sends email notifications to public mailing lists

PLEASE do not enable the production consumer unless you're absolutely sure it's your job to create the official events.

The fedmsg config keys for the consumers are relvalconsumer.test.enabled and respectively.
