Re: sync-engine segmentation fault - kdepim

Dear Mark,

Sorry for the delay in answering...

I've tried to clean my system so to correct any version issues. This is an
account of that and the install part.

Went through the installed packages list purging all that I found related to
the installed packages from the howtos

$> dpkg-query -l *sync*
$> dpkg-query -l *dccm*
$> dpkg-query -l *rra*
$> dpkg-query -l *rapi*
$> dpkg-query -l *multis*
$> dpkg-query -l *opensync*

Packages kitchensync and libpisync1 were not remove as they are used by
kdepim and gnome-pilot respectively.

Did
$> rm -rf ~/.synce

And removed the python-wbxml package.

Installed packages:
# apt-get install odccm librra0-tools librapi2-tools multisync-tools
opensync-plugin-kdepim opensync-plugin-synce

Removed the byte compiled file:
# rm -f /usr/lib/opensync/python-plugins/synce-opensync-plugin-2x.pyc

Tested from what package is sync-engine:
$> whereis sync-engine
sync-engine: /usr/bin/sync-engine

$> dpkg-query -S /usr/bin/sync-engine
synce-sync-engine: /usr/bin/sync-engine

>From the ouput of sync-engine 2 partnerships already exist (with the same

However they are not configured in ~/.synce as this is a "new install" and
they were created on the device prior to.
To delete them I installed synce-kpm (the delete_partnerships.py gave the
same error as the list_partnerships.py)

# apt-get install synce-kpm

Using synce-kpm I deleted the old Linux partnership and created a new one:

sync-engine doesn't need python-wbxml anymore, exactly what error did

The pyc file is a byte compiled version, it's an annoying packaging
quirk which is probably easy to fix if we knew how :) I don't know if it
will matter, but I would recommend manually deleting the pyc version for
now.

You also don't mention creating a partnership, eg with
create_partnership.py, have you done this.

If you are using sync-engine 0.11.1, it definitely does not use pywbxml.
The only way I can think you'd get this message is if you have an old
version somewhere that is being used instead.

No, if you mean the result from msynctool --listgroup, that is the sync
group, not the partnership. You also need to use create_partnership.py.

Oh, hang on, I see from the sync-engine log that you do have a
partnership, in fact you have two with the same hostname. Is this
intentional ? (use list_partnerships.py to see them)

I don't know if this might cause a problem ?

Can you try running sync-engine under gdb and get a backtrace ? If you need pointers just shout.

I think you still have some version clashes somewhere with sync-engine,

Here we are, you installed sync-engine 0.11.1, but the above traceback
involves files versioned 0.11, which did need pywbxml.

Have you always installed packages, or did you install an older version
from source ? If it can't possibly be from a package, I would recommend
deleting the /usr/lib/python2.5/site-packages/SyncEngine-0.11-py2.5.egg
directory.

Yep, this is a recent thing involving invalid xml, you did the right

/usr/share/pyshared/SyncEngine/kernel.py is installed from the 0.11.1
package and is correct. That 0.11 directory from above is messing it up.

Not sure about this, could be another version mismatch I suppose. Fix
the sync-engine version problem and see if this goes away.

This shouldn't cause a problem - partnership matching is done by
ID/GUID.

Dear Mark,

Here we are, you installed sync-engine 0.11.1, but the above traceback

That was indeed the problem.
After removing the dir:
* sync-engine didn't segfault on msynctool --sync
* list_partnership.py (and create) worked ok

Don't remember how did that dir got there (I checked and it wasn't from any
package).
A while ago I did install some synce manually (from source), but it was a
while...
That was perhaps the issue.

Thank you so much for all the help,

After removing the dir I deleted the partnership previously created with
synce-kpm (doing just the msynctool --synce wasn't syncing anything).
After creating a new partnership with synce-kpm all the events/todos were
synched to the pc (not yet to kdepim).
I re-created the group in msynctool and did the sync.
It now seems to be working fine, events created in kdepim "go to" PDA and
vice-versa (after the msynctool command).

I did lose several events.
Before syncing I had a blank korganizer and all the events in the PDA.
After theses trials (removing dir, trying sync with the old
partnerships/groups, re-creating partnerships/groups, syncing again) I ended
up with several events missing (both in the PDA and kdepim). But perhaps I
should have started by re-creating the partnerships.
I'll try to recover them from Outlook.

Again my thanks for the support,

Cheers.

From my limited knowledge of python, it did look like a source install
by the directory name.

Good stuff. Afraid when it gets to the actual sync details I don't know
much. If you find a persistent problem post a full log, I'm sure it will
get John's attention :)
