Concurrent Affairs: The ReaderWriterGate Lock

摘要

One day I was working on a consulting project and came across a thread synchronization problem that I hadn't run into before. The company was creating a Web service and almost all the client requests that came into their server needed to access some shared data in a read-only fashion. Occasionally, a request that needed to modify the shared data would come in, and we needed to keep the data in sync. It sounded like the perfect scenario for using reader-writer locks (as I discussed in my June 2006 Concurrent Affairs column, available at msdn.microsoft.com/msdnmag/issues/06/06/ConcurrentAffairs).
