Description Ingo Ratsdorf 2011-02-06 10:52:01 UTC 
Application: akonadi_davgroupware_resource (0.1)
KDE Platform Version: 4.6.00 (4.6.0) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-26-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Opened Akonadi Console, clicked on imported tasks and resource crashed
The same happens when clicking on calendar, only Contacts work okay

The crash can be reproduced every time.

Hi Ingo,

Are you using self-compiled packages for all of KDE? I've never seen this behavior and would like to replicate your setup.

Cheers,
Grégory
Comment 2 Ingo Ratsdorf 2011-02-06 22:51:08 UTC 
Hi Grégory,

I am following the groupdav resource for quite a while and had an older version reasonably well working before some code was shifted from KCal to KCalCore, at which point I could not compile anymore as Kubuntu 10.04 had no headers and libs for it.
I yesterday upgraded to Kubuntu 10.10 and to KDE 4.6 RC which allowed me to make the groupdav latest version from Git.

Note: I have downloded the whole kdepim-runtime but made only teh groupdav resource and installed it.

All complied without glitches just two warning and linked fine, also installed correctly as far as I can tell.

Yet, the groupdavresource randomly crashes on startup. In akonadiconsule, it will only show contacts, not calendars or tasks. Selecting calendars or tasks will crash the resource.

My groupdav server is eGroupware 1.9.002 from SVN which is running fine with the old pre KCalCore groupdav resource on another machine.

I had to patch the CMakeList.txt file in order to compile and install the groupdav client.
I added the usual KDE requirements plus the kcfg_ macro, that I can never find in any packed or some reason.
Nevertheless as I said, it compiled and linked fine.

Currently, he latest groupdav resource does not work at all for me.

Regards,
Ingo
Comment 3 Grégory Oestreicher 2011-02-07 22:38:51 UTC 
Hi Ingo,

I'm still not able to compile the latest DAV resource on Kubuntu 10.10. One issue is the missing kcalcore. Then I had to hack through the CMakeLists.txt, as I guess you did, to change the minimum versions required. Even if I was able to compile the resource, I would have put a big red flag on using such versions.

As a final note, and as you are using eGroupware, can you try to apply the changes mentioned in this bug report : https://bugs.kde.org/show_bug.cgi?id=265096 and tell me if that helps.

Cheers,
Grégory
Comment 4 Ingo Ratsdorf 2011-02-08 06:46:51 UTC 
Hi Grégory,

I applied the mentioned patch which seems to make the pre KCalCore groupdav resource work without throwing warnings about invalid data.
Yet it has no influence on the latest groupdav resource.
I used wireshark to trace HTTP requests and responses.
All REPORT calls seem to go through fine, but EVERY TIME the groupdav sends a GET and received a (good looking) response from the server, the resource will crash. Very funny.
This is a typical request and response directly before the resource crashes:

I'll try to recompile and see what happens. This is all too strange.

Comment 5 Ingo Ratsdorf 2011-02-08 11:32:30 UTC 
Hi.

I should chnage the bug title, actually. The resource crashes whenever an actual calendar element is fetched from the server, ie every GET.
This applies only to VTODO's and VCALENDAR's, not VCARD's. VCARD's load fine.

In that respect, I have included some console output just before the crash:

I guess from the above, that Akonadi cannot serialise the VCALENDAR information received, for whatever reason. As per my previous comment, the elemnt is returned correctly from the server.

I have meanwhile recompiled the resource: NO CHANGE IN BEHAVIOUR.

Hi Grégory,

did you have a chance to look into this?
Any chance that you could send me a binary copy of your version (I386)?

Cheers,
Ingo

Hi Ingo,

> did you have a chance to look into this?

I still haven't managed to get the resource to compile on KUbuntu 10.10, 
mostly because I'm not familiar with this distro and can't find where to get 
the KCalCore headers. Where did you get yours from? If you give me the repo 
you used I'll be able to at least compile, which would be a great progress for 
this report :)

> Any chance that you could send me a binary copy of your version (I386)?

I'm developing and compiling in a non-standard location, and with trunk, so I 
doubt my binaries will help here. If I recompile the resource cleanly, no 
problems to send you this.

Cheers,
Grégory

Official news:
The groupdav resource only works with the latest version of KDE with a certain serialiser installed that - as I understand - ships as part of the kdepim-runtime lot.
If you just install this resource without all the rest - it will not work and throw an exception.

I have now backported all calls of KCalCore back to KCal. And I can confirm the resource is now working.

Apart from the fact that it is useless in KOranaiser and Kontact because you cannot select the resource when adding events. I figured out that you can only select Akonadi resources, but no "folders" so to speak, which the groupdav resource represents - a folder with todos, tasks and addressbooks within it.
Does that maybe needs a new Korganiser and Kontact as well?

Nice work :)

Yes, the DAV resource stores all discovered collections (calendars, to-do lists,
address books) under a common root, that is represented as a directory. KOrg 4.4.x and
previous do not display the collections recursively. This requires a 4.6beta release.
Hopefully RC1 will be tagged soon, giving you a more stable environment to work into
than what may be the case with the latest beta.

Cheers,
Grégory
