Optimistic concurrency
May 10th, 2006
During the WB Editor 2.5 testing, we found an interesting concurrency control issue. In this version, we allowed multiple program instance for ease of cross posting.
Now in multiple instance windows, user can setup blog server accounts differently. Which one is the winner?
“Last one wins” was disapproved by QA.
Maybe we need optimistic concurrency. I this case user will receive a dialog saying “another instance has modified the settings”, do you want to overwrite or discard or reload?
Another option is concurrency control with change notifications. Using FileSystemWatcher to detect changes of configuration file, but what should happen next in UI?
