Source code for galaxy.exceptions

"""This module defines Galaxy's custom exceptions.

A Galaxy exception is an exception that extends :class:`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.
