Error handling

In Lilota, external code is executed. Errors that occur in the executed scripts are normally caught and handled by the worker.

If an error cannot be caught by the worker, or if an exception stops parts of Lilota and leaves the system in an inconsistent state, this is reflected in the error property of the Lilota class. This property returns the last fatal error encountered by the system that was not handled by a worker.

The Lilota class also provides two methods to:

Check whether a fatal error has occurred (has_failed) Wait until a fatal error occurs (wait_for_failure), which blocks execution
