Re: shared xDAV resources

2018-04-07 Thread Bron Gondwana 
Ken knows this code best.  I bet there's something which is requiring
that there's a user on the mboxname because we implement the same
behaviour at FastMail by having a separate user on which shared
resources are kept.  The DAV resources are stored per-user, and
without a place to keep them for "shared calendars" that code might
just not be accessible.  I'm sure it would be possible to create a
shared DAV database as well for this case, but it just needs some
programming effort.

shared xDAV resources

2018-04-07 Thread Anatoli 

Hi All,

I'm trying to understand the code responsible for enumerating user 
calendars (and xDAV resources in general) to try to make the discovery 
work for shared resources too (currently there's no way to access shared 
resources with Apple xDAV client implementation, yes with Thunderbird as 
it doesn't use the discovery mechanism, but instead should be pointed to 
the exact URL for each calendar). If I understand it correctly, the 
functionality is in imap/http_caldav.c.


Could you please point me to the place where the enumeration occurs and 
briefly mention how the general workflow looks like?


The client asks for:

PROPFIND /dav/calendars/user//


...

The server responds with:

HTTP/1.1 207 Multi-Status


  
/dav/calendars/user//
    
...
  
  
/dav/calendars/user//Default/
    
  
...

The idea is to include in the returned lists the shared calendars too 
with the discovery logic based on the IMAP shared folders.


Below goes the initial exchange between the calendar app on iOS 10.2.6 
and Cyrus 3.0.5 when the exact URL (/dav/calendars/shared/) for the 
shared calendar is provided in the advanced settings of the app (the URL 
finally resets to the user principals folder 
(/dav/principals/user/t...@domain.com/) as iOS is pointed to it by Cyrus). 
In the attached file goes the telemetry for the rest of the communication.


Thanks,
Anatoli
