[platform-team-dev] ISaveContext.needDelta()

["Vladimir Grishchenko" <vladgri@xxxxxxxxxxx>]

Hello,

I'm trying to understand how the ISaveParticipant mechanism is used by the CVS integration.
ISaveContext.needDelta() method is never called by the CVS plugins but there is an attempt to
process saved resource deltas in FileModificationManager.registerSaveParticipant(). Documentation
for ISavedState.processResourceChangeEvents() explicitly states that no notifications will be
available for past events if the method in subject wasn't previously called. If I'm interpreting
documentation correctly there may be an obscure bug in the CVS integration which never surfaced
because CVS plugins are likely to be initialized on startup because decorators are typically
enabled.

Thanks,
Vladimir.
