WaiverDB

What is WaiverDB

WaiverDB is a companion service to ResultsDB, for recording waivers against test results.

Quick development setup

Install dependencies:

$ sudo dnf builddep waiverdb.spec

Configure Postgres on the local machine, with a waiverdb database:

$ sudo dnf install postgresql-server
$ sudo postgresql-setup --initdb
$ sudo systemctl enable --now postgresql
$ sudo -u postgres createuser --superuser $USER
$ createdb waiverdb

Create a local configuration file:

$ cp conf/settings.py.example conf/settings.py

Populate the database:

$ PYTHONPATH=. DEV=true python3 waiverdb/manage.py db upgrade

Run the server:

$ PYTHONPATH=. DEV=true python3 waiverdb/manage.py run -h localhost -p 5004 --debugger

The server is now running at http://localhost:5004 and API calls can be sent to http://localhost:5004/api/v1.0. All data is stored in the waiverdb Postgres database on the local machine. You can verify the server is running correctly by visiting http://localhost:5004/api/v1.0/about.

Adjusting configuration

You can configure this app by copying conf/settings.py.example into conf/settings.py and adjusting values as you see fit. It overrides default values in waiverdb/config.py.

Running test suite

You can run this test suite with the following command::

$ py.test-3 tests/

The test suite will drop and re-create a Postgres database named waiverdb_test. By default, it expects to have superuser access to Postgres on the local machine.

To test against all supported versions of Python, you can use tox::

$ sudo dnf install python3-tox
$ tox

Building the docs

You can view the docs locally with::

$ cd docs
$ make html
$ firefox _build/html/index.html

Viewing published fedmsgs

You can view fedmsgs published when new waivers get created by doing::

$ fedmsg-relay --config-filename fedmsg.d/config.py &
$ fedmsg-tail --config fedmsg.d/config.py --no-validate --really-pretty

WaiverDB CLI

WaiverDB has a command-line client interface for creating new waivers against test results. A sample configuration is installed as /usr/share/doc/waiverdb/client.conf.example. Copy it to /etc/waiverdb/client.conf and edit it there. Or you can use --config-file to specify one.

Usage: waiverdb-cli [OPTIONS]

  Creates new waivers against test results.

  Examples:

      waiverdb-cli -r 47 -r 48 -p "fedora-28" -c "This is fine"
or

      waiverdb-cli -t dist.rpmdeplint -s '{"item": "qclib-1.3.1-3.fc28", "type": "koji_build"}' -p "fedora-28" -c "This is expected for non-x86 packages"
