relvalconsumer is a fedora-messaging consumer for creating Fedora release
validation test events. 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.
As long as relval is also installed, relvalconsumer will also run the image size check on the newly-created event, whenever it creates an event.
hawkey library is also required. This is only available on Fedora and
RHEL and is only available from official package repositories, it is not
available from Pypi.
Optionally also relval itself, to run image size check tests on the created events.
Install the required external Python libraries, then use setuptools to install, e.g.:
python3 setup.py install
You will also typically need to do:
dnf install fedora-messaging python3-hawkey
A sample configuration file which is set up to listen for real compose events
on the production fedora-messaging bus is provided as
To use this, you must at least change the queue name from
00000000-0000-0000-0000-000000000000 to a unique and private string; the
official recommendation is to use a UUID generated by uuidgen. Then place the
You can then enable and start the consumer as a systemd service:
sudo systemctl enable fm-consumer@relvalconsumer sudo systemctl start fm-consumer@relvalconsumer
A configuration setting,
relval_prod, decides whether the consumer operates
in 'production' or 'test' mode. This is set in the consumer configuration
consumer_config section. In test mode:
In this mode it is fairly safe to play around with the consumer. You will need
a local fedora-messaging broker instance to be able to trigger the consumer at
will, though. Depending on how you set that up, you may also need to change
.dev. or similar.
PLEASE do not enable the production consumer unless you're absolutely sure it's your job to create the official events.
