CardDAV / CalDAV connector

[Czo]

Hi,

I'm developing a CardDAV/CalDAV connector (first CardDAV because it's more important for me).

This is the first very-very-very alpha release, for testing.

What works currently:
- discover carddav server by domain's PTR and SRV DNS records. Users without proper dns settings also can specify the correct server path for CardDAV root.
- authenticate over https or http
- user principal, and carddav home directory (or server, because Apple's iCloud uses more than one server)
- download list of vcards
- identify contacts that need to be delete from local contacts, and identify witch need to be download from the server
- download vcards from the server
- parse downloaded vcards, and dump vcard data to /var/log/messages

How it works:
user can specify the username in username@domain.tld format, if you using icloud you need to write your@icloudaddress.com@icloud.com. If your server don't have correct SRV/PTR records, u can specify server with username@https://your.cardavserver.tld/

Currently i have problems with error reporting back to user (the example code on hp's developer site not working on touchapad (but it works on webos 2.1 in emulator))

So anyone can help me, with testing the proper login, and sync with more and more carddav servers. In development i'm testing with DAViCal and Apple's iCloud.

If you install the package, it's create a dummy application (how can i hide this applicatin, the sdk documentation says somethings, but it's not work on touchpad), then watch syslog on device(novaterm, and tail -f /var/log/message). After you watching the logs, please add the account (on touchpad, you immediately return to final step, before i can checks anything, on WebOS 2.1 i can notify user about wrong username/password/server address etc.)

In syslog you can see somethings like this:

checkCredentials args ={"username":"czo@czo.hu","password":"********","templateId":"hu.czo.carddavsync.contact","config":{ }}
Discovered username: czo
Discovered servername: czo.hu
Try to resolve _carddavs._tcp.czo.hu
Resolve via SRV record: _carddavs._tcp.czo.hu
SRV Reply: {"priority":0,"weight":1,"port":443,"name":"XXXXXXXzo.hu"}
SRV Valid Reply: {"priority":0,"weight":1,"port":443,"name":"XXXXXXXzo.hu"}
SRV Saved Reply: {"priority":0,"weight":1,"port":443,"name":"XXXXXXXzo.hu"}
Found SRV - domain: XXXXXXXzo.hu
Resolve via TXT record: _carddavs._tcp.czo.hu
TXT Reply: "path=/"
We found a valid HTTPS DAV server: https://XXXXXXXzo.hu/
Auth OK
Found principal path: /caldavXXXXXXX/czo/
Found home-set: /caldavXXXXXXX/czo/
Found addressbook resource: ["https://XXXXXXXzo.hu/caldavXXXXXXX/czo/address/"]


After you see the last line, finalize account setup, and go to Contacts app. In settings of contacts app, press the sync button. You see more and more 'Creating {"resource" …' lines, and finally you see all of your contacts on the dav server

If anyone can test this code, anything other than iCloud or davical, please send me back the logs, if you can't see your contacts in syslog (because auto error, or any other problem). Please strip password, because i dont't need it!

thanks.

Downloading now! This will be exciting!

I have an ownCloud setup at my apartment. I think it has CardDAV.

Are you intending to release this as open source? (If so, I'll probably dig into the code a bit to help out.)

Hi, I tried to test it on WebOS 2.2.4 (Pre3 emulator) but got almost nowhere:

Any thoughts?

Any thoughts?

I had to modify the synergy service to work with my server. There was very little log output, IIRC.

The Tellurium messages are benign. They are some testing framework, I have been told, and do not affect applications/services.

any update?
i've just tried this with owncloud but it doesn't work .. or al least not well

the log say that can find the principal path, but owncloud have the addressbook in a (i think different path)
so the app say:
the request is not suitable for the current configuration

any idea?

Hi,

Is there still somebody working on it?
I would be glad to pay for a working calDAV / cardDAV Synergy Connector. (5-10$ would be OK for me for a good working solution.)
(If it will come out in a decent time frame. As I am working with a new client company, where this data exchange (calDAV / cardDAV) is required.)

It would really be a pain, if that would be the reason to leave webOS!
