waiverdb 0.12.0

An engine for storing waivers against test results.

# WaiverDB


## What is WaiverDB

WaiverDB is a companion service to
[ResultsDB](https://pagure.io/taskotron/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"


Options:
-C, --config-file PATH Specify a config file to use
-r, --result-id INTEGER Specify one or more results to be waived
-s, --subject TEXT Specify one subject for a result to waive
-t, --testcase TEXT Specify a testcase for the subject
-p, --product-version TEXT Specify one of PDC's product version
identifiers.
--waived / --no-waived Whether or not the result is waived
-c, --comment TEXT A comment explaining why the result is waived
-h, --help Show this message and exit.
