libsyncml goes into infinite loop trying to sync from Sony-Ericsson P910i

Description (Last modified by felixmoeller)

Trying to sync my SE P910i phone using syncml-http-server (same problem also observed when using msynctool with the syncml-http-server plugin from opensync) the process gets into an infinite loop.

Phone firmware is R2A17 (old, but the latest one supplied by my service provider. >_<

The phone shows 'Connecting' the whole time, until the process is interrupted

The command I'm running is: 

syncml-http-server --port 8080 --sync text/x-vcard Contacts --sync text/x-vcalendar Calendar --sync text/plain Notes --sync text/x-vMessage Email --dumpinfo  --multi

This is a copy of libsyncml built from source:/trunk@317 without any particular build options set. It also happens with 0.4.5 (Debian version 0.4.5-1) but with less information in the trace log.

I've attached the tracelogs, and a packet capture of the communications, as well as the output of the program.

It's refusing to add the output of the process as an attachment, so here it is:

Hmm. Just noticed the
<--- ERROR --- _smlXmlDevInfDataStoreAssemble: Missing rx-pref
in the log, and thought I'd better highlight it here

dgollub suggested via IRC:
"i guess without those parameters it would work: --sync text/plain Notes --sync text/x-vMessage Email"

And indeed, it does work, with caveats.

Calendar-only sync fails with
"Didnt receive a reply for pending status (cmdID 5, msgID 2)"
although at this point it has already sent (I believe) all the Calendar entries, and the phone itself has cycled from Reading to Writing (sent 431 events) to Reading to Writing (remaining 238 events).

Contacts-only sync works the first time, but fails the second with time with
"Didnt receive a reply for pending status (cmdID 5, msgID 2)"
, although I have seen reports that failing to send contacts a second time is a known flaw in the phone software (I think the opensync.org phone compatibility list mentions this).
