REV MUST NOT appear more than once in a VCARD component

dervomsee

Hello,
i have a CardDAV Sync error on the combination of DAVdroid 1.3.4.1-ose, Nextcloud 11.0 beta and Contacts 1.5.2.

My phone produces the following debug.txt. Some fields are anonymized.
http://pastebin.com/KqNtMWg5

Is this error a DAVdroid problem or a Nextcloud beta problem?

Best regards,
Cornelius

I wonder where

REV;VALUE=timestamp:2016-11-19T17:44:22.057Z

comes from and what it should mean. The REV value should be in timestamp format (e.g. 19961022T140000Z). So it seems that ez-vcard/vcard4android can’t parse the original REV value in the VCard and thus preserves it as an unknown property (I’ll check that again).

This unknown property is then used again to build new VCard, while a correct REV value is added, too. So there are two REV values, which is not allowed.

Proposed solution: Please change your VCards so that they use common REV value formats before downloading them with DAVdroid.

rfc2822

I have now added a test which checks whether invalid REV values as in your VCard are retained as unknown property and it seems that this is really the problem.

I don’t know whether 2016-11-19T17:44:22.057Z is really invalid. According to RFC 6350 4.3.5 TIMESTAMP, timestamps are “complete date and time of day combination as specified in [ISO.8601.2004], Section 4.3.2.” ISO.8601.2004 references YY-MM-DDThh:mm:ssZ as such a format, but in your REV, there are not only integer seconds, but milliseconds.

ISO.8601.2004 also says: “If necessary for a particular application a decimal fraction of hour, minute or second may be included.”, so maybe this is a valid REV value and ez-vcard just can’t parse it correctly.

Do you know where the 2016-11-19T17:44:22.057Z value comes from?

Thank you for the very fast reply.
This is the last VCard, that produced a error:

BEGIN:VCARD[CR][LF]

END:VCARD[CR][LF]

The first timestamp 2016-11-19T17:44:22.057Z maybe is the last successful sync.
The second timestamp 20161127T153548Z is the last time, i’ve called the person.

If i open the nextcloud web interface, create a new contact for testing and download the VCard via the web interface, nextcloud 11 creates the following VCard:

Seems that Owncloud Contacts generates a REV value by using JavaScript: new Date().toISOString() since 2 Sep master or 1.5.2 (which was released 2 days ago).

new Date().toISOString() generates timestamps in the format YYYY-MM-DDTHH:mm:ss.sssZ or ±YYYYYY-MM-DDTHH:mm:ss.sssZ.

As shown above, ez-vcards doesn’t recognize these values as REV timestamps.

So, the question is now whether new Date().toISOString() generates a “A complete date and time of day combination as specified in [ISO.8601.2004], Section 4.3.2.”, as required by RFC 6350. Especially interesting would be whether a complete date/time combination is allowed to have decimal fractions in the seconds part.

The answer to this question is the key to know where the problem is:

If decimal fractions in the seconds part are allowed, ez-vcard (“DAVdroid”) should be able to parse the REV.
If decimal fractions in the seconds part are not allowed, the REV values generated by Nextcloud Contacts 1.5.2 would be invalid.

So, we need to answer this question before the problem can be solved.

rfc2822

In appendix B.2.3 of ISO.8601.2004, these examples of complete date and time combinations are shown:

YYYYDDDThhmm / YYYY-DDDThh-mm
YYYYMMDDhhmm,m / YYYY-MM-DDhh:mm,m
YYYYWwwDThh,hhZ / YYYY-Www-DThh,hhZ

So it seems that even ordinal dates (day of year), hour fractions etc. are valid values. So ez-vcard probably needs to import a special library to parse ISO.8601.2004 dates, in order to understand TIMESTAMP values …

@rfc2822 here is a fix for the owncloud contacts app - https://github.com/owncloud/contacts/pull/536

Please let me know if this work now for you - THX

dervomsee

No, its not working. I’ve commented already in the github issue.
Thank you for your work!

rfc2822

@DeepDiver Thanks, that should fix the problem.

@dervomsee

Please make sure that your server doesn’t serve any VCard with the questionable REV time format.
After that, synchronize all contacts again. You can delete the DAVdroid account and add it again (or de-select the address book, synchronize, select it again, synchronize).

Hello, I have also this issue. It begins with updating some contacts with profile pictures. The Pictures have the jpg file type.
This is the error message at the nextcloud backend:

Sabre\DAV\Exception\UnsupportedMediaType: HTTP/1.1 415 Validation error in vCard: REV MUST NOT appear more than once in a VCARD component.

I have also reference this issue here: Github contacts issue media type

rfc2822

@Lars This is not related to profile pictures.

Please make sure that your server doesn’t serve any VCard with the questionable REV time format (i.e. apply the OwnCloud Contacts fix and then correct invalid VCards).
After that, synchronize all contacts again. You can delete the DAVdroid account and add it again (or de-select the address book, synchronize, select it again, synchronize).

Lars

I think I found the issue myself. I added an gif

pulcov

Hello,

I have the same issue. Since i have upgrade nextcloud server to 11.0 all modifications made on the phone failed on sync.
Davdroid seems to add second REV value.
Is this bug will be corrected to next release ?
I can make tests if necessary.

Best regards,

hulmfire

The same happened to me. I updated NextCloud from 10 to 11 (latest contacts app 1.5.2). Syncing worked fine for half an day and then suddenly I get this error while syncing contacts. It looks like Davdroid is sending invalid data to the server. Why does this happen and how can I correct this problem?

Thank you!

Why does this happen

Please read this thread.

and how can I correct this problem?

Please upgrade to a version of Nextcloud Contacts where the problem has been fixed.
Make sure that your server doesn’t serve any VCard with the questionable REV time format.
Synchronize all contacts again. You can delete the DAVdroid account and add it again (or de-select the address book, synchronize, select it again, synchronize).
