Background

Hey, I am trying to modify a contact within an app-controller, but for some reason the modified contacts are messed up during the storage process. I looked at the sources, but could not find out if its a bug or just me misunderstanding the headers. Tried to search in the documentation, but only found an empty page at https://docs.nextcloud.com/server/latest/developer_manual/api.html . That brings me here...

Steps to reproduce

1. grab a contact $contact = $addressBook->search($contactId, ['UID'], [])[0];
2. make a copy $changed = $contact;
3. change it (or not)
4. save it $addressBook->createOrUpdate($changed);
5. verify: $addressBook->search($contactId, ['UID'], [])[0];

Expected behaviour

The contact is changed (or not) and remains with correct syntax.

Actual behaviour

The contact fields are not as expected:

the contact:
array(9) { ["URI"]=> string(40) "EBD3B9AA-FC6E-45DF-9294-C069141DA1F0.vcf" ["VERSION"]=> string(3) "4.0" ["PRODID"]=> string(28) "-//Nextcloud Contacts v3.2.0" ["UID"]=> string(36) "5ee6e61a-e281-47c6-ab17-11fb37bb7740" ["REV"]=> string(16) "20200417T190130Z" ["FN"]=> string(4) "Test" ["ADR"]=> string(6) ";;;;;;" ["EMAIL"]=> array(1) { [0]=> string(0) "" } ["TEL"]=> array(1) { [0]=> string(0) "" } }

the updated contact (identical):
array(9) { ["URI"]=> string(40) "EBD3B9AA-FC6E-45DF-9294-C069141DA1F0.vcf" ["VERSION"]=> string(3) "4.0" ["PRODID"]=> string(28) "-//Nextcloud Contacts v3.2.0" ["UID"]=> string(36) "5ee6e61a-e281-47c6-ab17-11fb37bb7740" ["REV"]=> string(16) "20200417T190130Z" ["FN"]=> string(4) "Test" ["ADR"]=> string(6) ";;;;;;" ["EMAIL"]=> array(1) { [0]=> string(0) "" } ["TEL"]=> array(1) { [0]=> string(0) "" } }

the return value of the update function (identical):
array(9) { ["URI"]=> string(40) "EBD3B9AA-FC6E-45DF-9294-C069141DA1F0.vcf" ["VERSION"]=> string(3) "4.0" ["PRODID"]=> string(28) "-//Nextcloud Contacts v3.2.0" ["UID"]=> string(36) "5ee6e61a-e281-47c6-ab17-11fb37bb7740" ["REV"]=> string(16) "20200417T190130Z" ["FN"]=> string(4) "Test" ["ADR"]=> string(6) ";;;;;;" ["EMAIL"]=> array(1) { [0]=> string(0) "" } ["TEL"]=> array(1) { [0]=> string(0) "" } }

but the stored contact (not identical, see ADR):
array(9) { ["URI"]=> string(40) "EBD3B9AA-FC6E-45DF-9294-C069141DA1F0.vcf" ["VERSION"]=> string(3) "4.0" ["PRODID"]=> string(28) "-//Nextcloud Contacts v3.2.0" ["UID"]=> string(36) "5ee6e61a-e281-47c6-ab17-11fb37bb7740" ["REV"]=> string(16) "20200417T190130Z" ["FN"]=> string(4) "Test" ["ADR"]=> string(18) "\;\;\;\;\;\;;;;;;;" ["EMAIL"]=> array(1) { [0]=> string(0) "" } ["TEL"]=> array(1) { [0]=> string(0) "" } }

Also trying the types-option did not change things $contact = $addressBook->search($contactId, ['UID'], ['types' => true])[0];, as the function seems to convert the array to vCard. For me it looks like there is a bug happening somewhere behind that.

@skjnldsv, @ChristophWurst can you help me here?

Maybe it's because createOrUpdate is not expecting the same result as what search returns? For example ADR is most likely expecting an array [], and not a string of semi-colons :)

Or this is a bug in the serialize methods

Regarding data, we're using the library sabre/dav & sabre/vobject
So you have documentation there: https://sabre.io/vobject/vcard/

Thank you for your instant reply!

I think it is just taking the identifier of the contact and then downloading the vCard, so the search doesn't have an impact here.

Also, they apparently recommand to not use createProperty anymore
https://sabre.io/vobject/upgrade_to_3/#creating-properties

Can you make sure it still misbehave with ->add directly?

Unfortunately it didn't change things when I modified /var/www/html/apps/dav/lib/CardDAV/AddressBookImpl.php, replacing the createProperty by add. Even though the linked description sounded like it could help.

I commented on the contacts draft pr as well :)

What's the status of this issue btw?
