Re: [Davical-general] Free/Busy using Thunderbird Lightning

[Felix B. (Mailinglist) <fb...@lt...>]

Some more information...

I have enabled freebusy debugging by adding the following line to my 
configuration file: '$c->dbg["freebusy"] = true;'. Now the following 
gets logged:

davical: DBG: freebusy: User agent: Mozilla/5.0 (Windows; U; Windows NT 
5.1; en-US; rv:1.9.2.15) Gecko/20110303 Lightning/1.0b2 Thunderbird/3.1.9
davical: DBG: freebusy:Unhandled request method >>PROPFIND<<
PHP Notice:  Undefined variable: raw_headers in 
/usr/share/davical/htdocs/freebusy.php on line 81
davical: DBG: freebusy:HEADERS: array is not set, or is not an array!
davical: DBG: freebusy:_SERVER: >>HTTPS<< = >>on<<
...

So the 'wrong' request method is 'PROPFIND' (instead of 'GET'). There is 
definitely something wrong here...

A probably important although understood note: when creating a new 
calendar in Lightning (no matter if it should display all data about 
events or just free/busy information) I use 'CalDAV' format _not_ 
'iCalendar (ICS)'.
If I use ICS format instead (which I think is wrong) free/busy 
information for my friend gets displayed correctly if I use 
'caldav.php'; if I use 'freebusy.php' (still with the wrong format ICS) 
Lightning does not show the exclamation mark (which is fine) but the 
entries are still not displayed (see my initial post about 'VEVENT' 
versus 'FREEBUSY').

I hope that this analysis is neither too detailed nor too confusing, Felix
