Exceptions in Concurrent Eiffel
We describe the problem of asynchronous exceptions in Eiffel’s Simple Concurrent Object-Oriented Programming (SCOOP). We discuss a range of possible solutions to further enable dependable computing in concurrent Eiffel. We propose a mechanism to handle aynchronous exceptions via a limited developer choice, including the notion of a failed or dead object, and necessarily introduce a small number...
متن کاملPredicting Temporal Exceptions in Concurrent Workflows
Current Workflow Management Systems (WfMS) are capable of managing simultaneous workflows designed to support different business processes of an organization. These departmental workflows are considered to be interrelated since they are often executed concurrently and are required to share a limited number of resources. However, unexpected events from the business environment and lack of proper...
متن کاملAsynchronous Exceptions in Concurrent Object-Oriented Programming
Exceptions in concurrent object-oriented languages with asynchronous call semantics may raise a serious problem in certain situations. Since separate calls are asynchronous it might happen that the context of the enclosing routine, from which the asynchronous call was launched, has been already left and hence any exception raised by the asynchronous call can not be handled anymore by the enclos...
متن کاملConcurrent Object-Oriented Programming: The MP-Eiffel Approach
concurrent programming Since we are interested in the essential properties of concurrency, we don’t want to bind our concurrent processing entities to specific “lower level” realizations such as threads, processes, object request brokers, MPI, PVM, or any other. Instead, we will use an abstract notion of “processor” adapted from Meyer [Mey97, page 964]: A processor is an autonomous thread of co...
