Looney is a system that schedule updates of databases based on the frequency and the scripts provided by the user. The parameters and the scripts are provided as python programs, which are loaded at the initial run of the system.
The system takes care of the directory structure for the different versions of a database, and generates symbolic links to the current version as well as to other versions if requested by the user.
v0.3
- Invalid plugins are skipped, instead of stopping the execution.
v0.2
- Modified to use pip packaging system
Let's assume the following locations (more on this later):
- datatabase repository: ~/databases
- time-tagged databases: ~/databases/.store
- system: ~/databases/.system
- plugin repository: ~/databases/.plugins
The first step is to create the desired directory structure:
$ mkdir ~/databases $ mkdir ~/databases/.system $ mkdir ~/databases/.store $ mkdir ~/databases/.plugins $ cd ~/databases/.system
Create a virtual environment for pip-installing looney and its dependencies
$ virtualenv venv $ pip install looney
The setup script run by pip will install the script in ~/databases/venv/bin/ and all the necessary dependencies
The second step is to have a configuration file that is consistent with the directory structure. The program takes as an optional argument a configuration file
| -h | print this message |
| -c configfile | location of the configuration file to use |
If no configuration file is provided, scheduledb will use the default configuration file located at ~/databases/venv/lib/python <python-version> /site-packages/scheduledb/scheduledb.ini
Once installed, the looney script should be installed and searchable in the path.
