There appears to be a detail missing from the RFC - when no changes have occurred since the last refresh, for refreshOnly the provider will send a Sync Done refreshDeletes control with no cookie. I.e., if the state hasn't changed, the cookie would be identical, so there's no need to send it back to the consumer.
You say Sync Done refreshDeletes, that is indeed what you get with refreshOnly. However, with refreshAndPersist you get a single syncInfoMessage of refresh*Present*. Shall I report this as a bug?
Please do, thanks.
My interpretation of 'no cookie' in the SyncDone/SyncInfoMessage was to use no initial cookie in the next synchronization. But your interpretation is probably better indeed.
For some reason I remember this being explicitly documented somewhere, but I can't find a reference now. Maybe Kurt will remember, if he's watching...
For refreshAndPersist it always sends the cookie back. I think this may be a bug, we probably shouldn't be sending the cookie in this case either. So, you *should* be able to assume that no changes have occurred at all when no cookie is returned.
Okay thanks, I'll use that assumption. I'll also use the assumption that if the cookie is the same, no changes have occurred.
Fair enough.
