A very simple JSON based API to store and report back on test
results from Ceph tests.
To install and use paddles:
- Install the following packages (names provided are based on an Ubuntu install):
git python-dev python-virtualenv postgresql postgresql-contrib postgresql-server-dev-all supervisor - Install and configure PostgreSQL on your system.
- Create a database. Ours is called 'paddles'
- Clone the repository
- Inside the repository, create a virtualenv:
virtualenv ./virtualenv - Create a copy of the configuration template:
cp config.py.in config.py - Edit config.py to reflect your hostnames, database info, etc.
- Activate the virtualenv:
source ./virtualenv/bin/activate - Install required python packages:
pip install -r requirements.txt - Run
python setup.py develop - Populate the database tables:
pecan populate config.py - Create a copy of the alembic configuration template:
cp alembic.ini.in alembic.ini - Edit alembic.ini to reflect your database information.
- Tell alembic that you have the latest database version:
alembic stamp head - To start the server for testing purposes, you may use
pecan serve config.py- though for production use it's wise to use a real server. We use gunicorn managed by supervisord. Sample config files are provided for gunicorn and supervisord. - To get teuthology talking to paddles add a line like this to your
~/.teuthology.yaml:results_server: http://paddles.example.com/
On GET operations it will display the latest 100 runs with a JSON
object of all recent jobs reported.

The example above gives returns the three result types available for jobs:
pass, fail, and running with its respective links. These are built
from the information for every run as the results come in. They are read-only
values. It will also report on the overall status of the run: running or
finished.
These operations create new entries for runs, it is only required to POST
a JSON object that has a name key and the actual name of the run as the
value:
{ "name": "teuthology-2013-09-01_23:59:59-rados-master-testing-basic-plana" }
HTTP responses:
- 200: Success.
- 400: Invalid request.
To read information for a specific run a GET needs to be requested. On
valid requests (for existing runs) a JSON object with all the jobs
scheduled for that specific run are returned. Below is an example of a valid
request:
{
"1500": {
"href": "http://paddles/runs/teuthology-2013-09-01_23:59:59-rados-master-testing-basic-plana/1500/",
"status": "running",
"results": {
"pass": 8,
"running": 13,
"fail": 2
}
},
"1501": {
"href": "http://paddles/runs/teuthology-2013-09-01_23:59:59-rados-master-testing-basic-plana/1501/",
"status": "finished",
"results": {
"pass": 8,
"running": 0,
"fail": 4
}
},
"1502": {
"href": "http://paddles/runs/teuthology-2013-09-01_23:59:59-rados-master-testing-basic-plana/1502/",
"status": "finished",
"results": {
"pass": 3,
"running": 0,
"fail": 17
}
}
}
GET requests will return a full list of all the jobs associated with the
current run.
If no jobs exist, an empty array is returned, otherwise this is how a single object would look like:
[
{
"archive_path": null,
"kernel": null,
"teuthology_branch": null,
"tasks": null,
"verbose": null,
"description": null,
"roles": null,
"overrides": null,
"pid": null,
"success": null,
"name": null,
"targets": null,
"owner": null,
"last_in_suite": null,
"os_type": null,
"machine_type": null,
"nuke_on_error": null,
"duration": null,
"flavor": null,
"email": null,
"job_id": "1"
}
]
POST requests with valid metadata for a job can create new jobs. Keys that
are not part of the schema will be ignored. Keys that are saved to the
database are:
- name
- archive_path
- description
- duration
- flavor
- job_id
- kernel
- last_in_suite
- machine_type
- mon.a_kernel_sha1 (note this key gets transformed to underscores)
- mon.b_kernel_sha1 (note this key gets transformed to underscores)
- nuke_on_error
- os_type
- overrides
- owner
- pid
- roles
- success
- targets
- tasks
- teuthology_branch
- verbose
- branch
- sha1
- suite_sha1
- pcp_grafana_url
For initial creation of a job associated to its run a job_id key is
required. It is the only key in the JSON body that must exist, otherwise
a 400 error is returned.
HTTP responses:
- 200: Success.
- 400: Invalid request.
- 404: The requested run was not found.
Note
updates for the results of these runs are programatically calculated from individual jobs
On GET requests an object with all metadata saved from the actual job will
be returned.
PUT requests can contain any of the keys accepted for metadata, they get
updated accordingly except for job_id. That is the one key that can
never be changed.
- 200: Success.
- 400: Invalid request.
- 404: The requested run was not found.
