[Opensync-users] opensync+isync breaks fast syncing, generates dupes

[Simon J. <si...@jo...>]

I have now isolated the problem that causes duplicates to be created.
This is with libsyncml 0.4.6 and opensync (core library, file-sync,
syncml, and msynctool) from svn.

First I sync the phone with isync on Mac OS X.  Then I create a opensync
installation, one syncml-obex-client and one file sink.  I sync once
first, which is a slow sync, populating the local file sink.  I sync
again, and this time it is a fast sync, with no changes.  I can also
force a slow sync, which also works fine with no changes.

The problem starts if I now sync the phone on the Mac.  The sync on the
mac works fine.

When I after that try to synchronize using opensync, things break.  What
happens is that opensync decides to do a fast sync.  Is that the correct
decision?

The output from this fast sync is below.

What happens is that opensync retrieves all entries from the phone, and
adds them to the local 'file-sync' sink.  The id's are the same, so to
avoid overwriting the file, it adds '-new' to each filename.  If I
perform this several times, I can get 'X-new-new-new' or even worse.

At this point, I have each entry twice in my local file sync.  If I
later sync again with the phone, it would probably transfer all entries
from the file sink back to the phone (I prevent this by making the
syncml-obex-client a read-only sink).  This rapidly creates a lot of
duplicates.

Any ideas?

I'll see if I can get a stable setup by always forcing slow-sync.
