[Opensync-devel] Question about UID storage and mapping

[Andrew B. <an...@cs...>]

Hi,

I'm writing a plugin to sync my mobile phone's calendar. Unfortunately, the=
=20
phone is fairly primitive and doesn't have any way to store UIDs on events,=
=20
just some of the event data itself: summary, time, duration, alarm time, an=
d=20
(a simple) recurrence type. Events are stored in slots 1-500, and once an=20
event is stored in a slot its slot doesn't change when it is modified. Ther=
e=20
is the possibility that an event could be deleted and another recreated in=
=20
the same slot; there is no way (other than heuristics) to distinguish this=
=20
from a modification, but I was going to ignore that problem for now.

I was hoping someone could give me suggestions on the best way to map slot=
=20
numbers to UIDs. From reading SynchronizationOverview in the wiki, it seems=
=20
that opensync allows a device to use its own UIDs and remembers the mapping=
=20
between the UIDs on all the different devices. Is that correct? In that cas=
e,=20
could I generate a UID that is basically just the slot number, and opensync=
=20
will take care of the rest?

If so, when I get a new event ADDED to the phone, how can I inform opensync=
=20
what UID it has received on the device? Just overwrite the uid field on the=
=20
change object before reporting success?

Thanks,
Andrew
