galaxy.exceptions package

This module defines Galaxy’s custom exceptions.

A Galaxy exception is an exception that extends MessageException which defines an HTTP status code (represented by the status_code attribute) and a default error message.

New exceptions should be defined by adding an entry to error_codes.json in this directory to define a default error message and a Galaxy “error code”. A concrete Python class should be added in this file defining an HTTP status code (as status_code) and error code (error_code) object loaded dynamically from error_codes.json.

Reflecting Galaxy’s origins as a web application, these exceptions tend to be a bit web-oriented. However this module is a dependency of modules and tools that have nothing to do with the web - keep this in mind when defining exception names and messages.
