Syncing is currently developer-level code - you need to be able to at least read logfiles! Testing is welcome; please report to the sync list (sync@lists.horde.org), but please keep in mind that the code is still in heavy development.
The sync URL is http(s)://pathtoyourhordeinstall/rpc.php
Username/password: your Horde account data
Databases (sometimes called remote settings) must be calendar, tasks, notes, or contacts.
For debug output create dir /tmp/sync and make it writeable by web server
Set log level to PEAR_LOG_DEBUG in Administration:Horde Setup_Logging. It may be helpful to filter the logs as follows:
tail -f /tmp/horde.log | grep "SyncML:"
For sync4j outlook syncing, use at least !SyncClient PIM Outlook version 1.3.9 available from sync4j.org (v 2.2). The device ID must be sc-pim-outlook or anything containing sync4j so that the Horde backend can identify the connector.
For devices using WBXML (P800/P900 and Sync4j don't, most others do) you need a recent (>=0.9) version of the wbxml2 library installed. See http://libwbxml.aymerick.com/.
++ Sync clients being used succesfully:
Synthesis client (v2.5.0.30) -> PDA -> USB serial cable -> Powerbook G4 running The Missing Sync (http://www.markspace.com/missingsync_palmos.php) -> Horde test installation
++ Cleaning up when testing
//##red|DO NOT USE THIS IN PRODUCTION!##//
If you're debugging and want to clean out data between sync attempts, you can try this set of commands if you use mysql (or adjust appropriately for other backends):
delete from kronolith_events where calendar_id='YOUR CALENDAR';
delete from horde_datatree where group_uid='syncml';
delete from horde_datatree_attributes using
horde_datatree_attributes left join horde_datatree on
horde_datatree_attributes.datatree_id=horde_datatree.datatree_id where
horde_datatree.datatree_id IS NULL;
You can clear all session files (assuming the default backend) with rm -f /tmp/sess_*.
You'll have a lot of entries in the datatree with a group_uid of 'horde.history'. You will lose information from more than syncing by clearing them out, but you can do so. It is also useful to clear out horde.log and /tmp/sync to get a better feel for what is from the current sync attempt and what is not.
