cardDAV mods duplicate cards on server side

[trollineto]

Hello all,
I have a problem with CardDAV.
It’s quite new, but can’t said when it began… As often, everything was working as expected until…

I can sync addresses to different directions (tested on an Android with DAVx, a Thunderbird 91 with own integrated cardDAV, and the same with the CardBook addon), but each time a modification is made on the client side, the syncing provide a duplicated vcf file.
As strange as it it, it doesn’t affect a lot some of the clients : the android+DAVx and the TB91.5+own CardDAV keep the right (last?) card. But CardBook seems to be more confuse and can’t process the sync anymore (with a weird message “contacts processed : 7/5”) : I have to shutdown TB and manually edit the prefs.js to remove the abonnement.
The eGW WUI show as the groupdav.php URL more and more cards, all with the same name, a different content (Displayname changed) and a new ETag, whitch is not the normal behaviour, and very annoying :

Collection listing: Address Book Test CardDAV
# 	Name		Displayname 	Last modified 	ETag 	Content type 	Resource type
1 	43403.vcf 	Afirst Testname 	2022-01-26 11:17:23 	"43403:0" 	text/vcard 	
2 	43403.vcf 	AfirstButMod Testname 	2022-01-26 11:21:19 	"43404:0" 	text/vcard 	
3 	43403.vcf 	AfirstButModAgain Testname 	2022-01-26 11:26:39 	"43405:0" 	text/vcard 	
4 	43403.vcf 	AfirstButModAgain TestnameAndagain 	2022-01-26 11:32:26 	"43406:0" 	text/vcard 	
5 	43403.vcf 	AfirstButModAgain TestnameAndagain 	2022-01-26 11:32:30 	"43407:0" 	text/vcard 	

It happens on two different servers. Can you help me ?

It’s a docker install all upgraded. The server is beyond apache redirections of another server, but I made the test without these redirections (the “internal” docker redirections untouched, of course).
I recently upgrade from Debian 10 to 11 “bullseye”.

Installed version : egroupware-docker (21.1.20211130) apt installed from suse’s repos on debian 11. debian’s mariadb installed from apt.

Many thanks for reading,

Hi Vincent.

Are you able to reproduce the behaviour and create a *DAV log?:

Access to EGroupware via WebDAV (CalDAV/CardDAV)

Hello Stefan,
Thank for your time,

Are you able to reproduce the behaviour and create a *DAV log?:

Yes I can reproduce the behaviour. Here are the log for DAVx5!4.1-ose (2021!12!29; dav4jvm; okhttp!4.9.1) Android!10.log.anon.txt (10,2 Ko)
and Mozilla!5.0 (X11; Linux x86_64; rv 91.0) Gecko!20100101 Thunderbird!91.5.0.log.anon.txt (10,9 Ko)

Hello all,
I’m investigating further…

Both servers are very long time upgrades : probably one from eGW v1.0 and the other from eGW v1.2. May be a hurt during an upgrade ?
I skipped v19 and upgraded directly from 17.1-epl to 20.1-docker (while upgrading, a server was running debian 8 while the other debian 9). Now, they’re both running debian 11.2.

I’ve checked for user rights but everything seems OK. I’ve tested with different users with same results.

There seems to be another problem : many vcards can’t be downloaded with direct links like :
https://egserver.mydomain.tld/egroupware/groupdav.php/myuser/addressbook/12345.vcf
while other ones are still accessible. Can’t find a reason for the moment.

The database’s table egw_addressbook show that duplicated cards share the same value for contact_uid and carddav_name. Only modified cards are duplicated, but other may have pb too.

History is activated.

Thanks for reading

I had the same issue.

At least I got three duplicates. Only difference seems the ID.

On the phone it shows only a single contact.

That Problem is solved with the last maintenance release a couple of days ago

Maybe that caused the doublication, can you recheck please?

Hi Ralf,
seems okay now. Thanks.

Hi Ralf,
Hi Stefan,

Yes, everything is working as expected now. After a little cleanup on egw_addressbook (nothing drastic, just remove duplicate cards) everything is back to normal.

Sorry to be so late,
Greetings
