Re: [Opensync-users] Assertion when ignoring mapping conflict

[Armin B. <arm...@de...>]

Right.

Here is the problem: Ignoring a conflict works by saving the ignored
uids of changes in a database. During the next sync, the devices wont
send the changes again, so i have to read them explicitly using a
special function. But if the plugin does not provide such function, the
assertion will be triggered.

Now we have 3 possible solutions to this:

- either make sure that every plugins provides a read function (not
really possible)
- if one of the plugins does not provide a read function, do not provide
a ignore resolution.
- if one of the plugins does not provide a read function, slow-sync the
next synchronization.

so... what do you think would be the best solution?
