airtime_analyzer
==========
airtime_analyzer is a daemon that processes Airtime file uploads as background jobs.
It performs metadata extraction using Mutagen and moves uploads into Airtime's
music library directory (stor/imported).
airtime_analyzer uses process isolation to make it resilient to crashes and runs in
a multi-tenant environment with no modifications.
Installation
==========
$ sudo python setup.py install
You will need to allow the "airtime" RabbitMQ user to access all exchanges and queues within the /airtime vhost:
sudo rabbitmqctl set_permissions -p /airtime airtime .\* .\* .\*
Usage
==========
This program must run as a user with permissions to write to your Airtime music library
directory. For standard Airtime installations, run it as the www-data user:
$ sudo -u www-data airtime_analyzer --daemon
Or during development, add the --debug flag for more verbose output:
$ sudo -u www-data airtime_analyzer --debug
To print usage instructions, run:
$ airtime_analyzer --help
This application can be run as a daemon by running:
$ airtime_analyzer -d
Other runtime flags can be listed by running:
$ airtime_analyzer --help
Developers
==========
For development, you want to install airtime_analyzer system-wide but with everything symlinked back to the source
directory for convenience. This is super easy to do, just run:
$ sudo python setup.py develop
To send an test message to airtime_analyzer, you can use the message_sender.php script in the tools directory.
For example, run:
$ php tools/message_sender.php '{ "tmp_file_path" : "foo.mp3", "final_directory" : ".", "callback_url" : "http://airtime.localhost/rest/media/1", "api_key" : "YOUR_API_KEY" }'
$ php tools/message_sender.php '{"tmp_file_path":"foo.mp3", "import_directory":"/srv/airtime/stor/imported/1","original_filename":"foo.mp3","callback_url": "http://airtime.localhost/rest/media/1", "api_key":"YOUR_API_KEY"}'
Logging
=========
By default, logs are saved to:
/var/log/airtime/airtime_analyzer.log
This application takes care of rotating logs for you.
Unit Tests
==========
To run the unit tests, execute:
$ nosetests
If you care about seeing console output (stdout), like when you're debugging or developing
a test, run:
$ nosetests -s
To run the unit tests and generate a code coverage report, run:
$ nosetests --with-coverage --cover-package=airtime_analyzer
