Abstract:

Runtime errors are divided into expected and unexpected; requirements for language support for systematic error handling are proposed. Popular approaches to error handing — exceptions and return codes – are analyzed. Automatic treatment of unexpected errors by means of restoring program state invariants is proposed. Based on the conducted analysis, several mechanisms of language support for systematic error handling which satisfy stated requirements are proposed.
