415376 - Lightning should support VFREEBUSY elements

Status: NEW

(Calendar :: Provider: ICS/WebDAV, enhancement)

Description

[Omar Bajraszewski]

Attachment: Google public calendar

Lightning and Sunbird don't display private events from public Google ics calendars (and maybe others). Google calendar displays them as 'busy'

Steps to reproduce:
1)Subscribe to public Google calendar with private events
Result:
The private events are not displayed

Expected result:
They are visible as 'busy'

Using the gdata provider, or via ics feed?

In the latter case, can you attach an ICS export? In the former case, the usual XML from the error console.

I subscribe it as remote ics (it doesn't matter whether with gdata provider or without):

The linked .ics file doesn't contain private events. Instead it contains VFREEBUSY elements, e.g. 

    BEGIN:VFREEBUSY
    DTSTART;TZID=Europe/Warsaw:20080125T080000
    DTEND;TZID=Europe/Warsaw:20080125T080000
    DTSTAMP:20080202T234350Z
    UID:[e-mail]
    URL:
    SUMMARY:Busy
    END:VFREEBUSY

I think Sunbird/Lightning supports only VEVENT and VTODO elements but not VFREEBUSY.

Correct, VFREEBUSY is not seen as an event. This could be an enhancement though. Omar, if you agree feel free to change the bug title.

I like this idea. Shouldn't be too hard to let ics provider feed free-busy service with that data. But the ics provider needs to know what calid/user relates to the calendar.

Comment 9

[Malintha Fernando [:marlio]]

Is this open still? I saw calFreeBusyService.js and calIFreeBusyProvider.idl is there. But seems still lightning does not support.

Comment 10

[Philipp Kewisch [:Fallen][📱📆]]

Yes, it is. Its a little different than the freebusy service. This bug is about displaying VFREEBUSY elements in an .ics calendar feed as "events" in the calendar view. This is not in scope for the GSoC Project you are looking into.

I might work on this but I need guidance because it would be my first patch for Thunderbird/Lightning.

As mentiond in the other bug, maybe a quick video conference would be good on this. Depending on your previous software engineering experience, you may want to start out with another easier bug to get used to the codebase before you venture into this one :-) Please email me for details.

(and btw, maybe you can change your display name to something other than "bugzilla.mozilla.org", given your name seems to be in your email address anyway :-)
