child pid 9283 exit signal Segmentation fault (11).

Hello,

We currently test the syncml functionnality of Horde. We try to synchronize
Outlook with kronolith. During these tests, we found a bug in the managment
of the user authorization. In the log file of Apache we have the message :
child pid 9283 exit signal Segmentation fault (11). The problem seems to
come from the key used to encrypt the user password. The GOST algorithm
required a key of 32 bytes and the one used is smaller (sessionid =
syncmlsc21). We temporarily corrected the problem by padding the value
up to 32 bytes.

What do you think about that problem ??

Thanks

That it doesn't have anything to do with Horde code. Apache/PHP5 must never
segfault, this is always a PHP bug.

If you think you have a solution, send a patch. At least give a file/line
number.

Re: (no subject)

Sorry for the late answer, but I haven't worked on it since 1 month.

I think that I finally found out why the wbxml2xml process open with 
proc_open was freezing on my server. It seem
that he freeze when reading the sdterr pipe (pipe #2).

With the CVS version of the XML_WBXML Decoder.php, wbxml2xml was 
freezing and was kept running by the server.
[root <at> courriels sync]# ps -A |grep wbxml2xml
24756 ?        00:00:00 wbxml2xml
24918 ?        00:00:00 wbxml2xml
26291 ?        00:00:00 wbxml2xml
26312 ?        00:00:00 wbxml2xml

But with my changes, everything work properly, anywhay, the stderr pipe 
for these proc_open calls wasn't used in the code.

I included in attachment the diff file of the changes I done to the 
XML_WBXML framework package.

No problem, thanks for getting back to it. :)

Sync4j and Horde

Hi folks,

I like to use Sync4j-Clients (i.e. the Outlook-Client) with the Horde 
SyncML-Server. I read the mailinglist-archive and found out that there 
has to be written a horde<->sync4j-connector.

Can anyone tell me why this is necessary? I thougt Horde's rpc.php 
supports SyncML (i.e. together with the SE P900) and Sync4j does, too. 
So why can't I use the Sync4j-Outlook-Client together with Horde?

Gruss,
   Ollie.

I don't know details about Sync4j but imho this only applies if you want to do
some integration of Sync4J Sync-*Server* and Horde (like using Horde as a
Datastore for the SyncServer).

Just using the Sync4j SyncConnector to Sync Outlook with Horde should work
without any extensive modifications. Just give it a try. Feedback whether it
actually works would be very much appreciated.

A method to Sync Outlook Data with Horde would surely be a good thing.

Cheers,
  Karsten

I wish I had better news, but it didn't work. The Sync4j-Outlook-Client 
says:
  Error code: 700
  Error message: SyncBody not found!

And this is what was send/received:

# cat /tmp/sync/syncml_client_1.xml

Re: Sync4j and Horde

Hi Oliver,

but at least it's a start. And the debug info does help.

I'm away from my Horde installation and cvs at the moment (and for the rest of
the month), so here are just two wild guesses:

1) currently Horde SyncML doesn't do "auth-clear" authentification. 
This should
be easy to fix:

replace line 250 of framework/SyncML/SyncML.php

$this->_credData = base64_decode($this->_credData);

with s.th. like the following:

if ($this->_credType == 'syncml:auth-basic') {
    $this->_credData = base64_decode($this->_credData);
}

After that you should get logging info with locName=okuhl in your horde debug
log rather than the current "locName=¢K¡-·°ŠZ"

2) But I think the real issue is that Sync4J doesn't like the empty xmlns tags
in

<SyncML xmlns="">

and especially

Oliver, if either of these work or improve things, let me know, and if 
Karsten's
away, I can get them incorporated into CVS.
