[Opensync-users] How to avoid collisions on UIDs

[<boe...@ht...>]

Hi all,

I'm writing a sync plugin for v0.22 but got a problem understanding the UIDs.
Assuming a group is newly set up with two plugins and a slow sync is started.
How can plugin A set an UID to a OSyncChange in get_changeinfo() without
knowing what UIDs plugin B is going to use for its changes? How can I avoid
collisions there?

Can I just increase the highest, locally known UID for a new entry with status
CHANGE_ADDED?
And do I have to reset the UID counter back to 0 when a slow-sync is requested?

Regards,
Eric
