carddav: PROPPATCH support for address books #147
Conversation

Does it help clients to advertise PROPPATCH here? Line 281 in 25f1014 |
Good call, but no. I tried, and it doesn't change anything. For DavX5, there isn't even an option to change it, which seems to be a known issue, and e.g. CardBook never does an OPTIONS request anyways. Evolution does do one, but still doesn't bother ¯\_(ツ)_/¯ |

Do we have to write out a multi-status here? Can't we just reply with a toplevel HTTP status instead? Something like internal.HTTPErrorf?

Would a 404 be more appropriate for the properties we don't know about?
OK, too bad. Can we still advertise |

Changed the interface so that the backend can implement UpdateAddressbook atomically, also simplified some things a bit. |
The groundwork for address objects is also there, but it's not fully implemented.
I'll be honest: none of the usual suspects (DavX5, TB/CardBook, Evolution) actually use this, but that just makes me mad. They all rename address books client side only (or not at all). However, since PROPPATCH is a standard WebDAV operation, I successfully renamed my address books on the server using cadaver. I still think this is worth implementing, because if any sane client ever comes along, they might really want to use this.
Regarding the support for address objects, it might be worth taking a closer look at the worthwhileness before going through with it. I suspect that again no major client actually uses it, and for address objects it's also slightly less useful (because e.g. the "displayname" property is likely not used, because a contact is displayed by its name, etc.).
