Fixing client-side issues on server

Dear all

Some of my clients send invitations that make use of weird time-zone
notations which davical complains about, e.g.

[Wed Nov 11 00:36:21 2015] [error] [client 5.148.175.85] davical:
***: ERROR:Could not recognize timezone "W. Europe Standard Time" - will
use floating time
[Wed Nov 11 00:36:21 2015] [error] [client 5.148.175.85] davical:
***: ERROR:Could not recognize timezone "(UTC+01:00) Amsterdam, Berlin,
Bern, Rome, Stockholm, Vienna" - will use floating time

Further, latest thunderbird/lightning on Win 7 launches requests which
davical complains about, e.g.

[Wed Nov 11 00:36:21 2015] [error] [client 5.148.175.85] davical:
LOG: request:Request is "REPORT" but client set content-type to
"text/xml;charset=utf-8". Assuming they meant XML!

What is the easiest way to just to transcode these things on server-side
to make them look properly specified for davical? Stored procedures?

Thanks
Lukas

PS: To anticipate: I do not look for a discussion on whether the author
at the client-side should fix it or not -- sometimes it is just not
possible.

That's probably not a client issue, but a server issue. There is no
requirement for a specific format of the time zone identifiers, neither
in CalDAV nor in iCalendar. So these time zone ids are fine and should
be accepted by the server (given there is a valid VTIMEZONE component in
the calendar data for these TZIDs).
Many other calendaring products have a mapping of these Microsoft names
to Olson IDs. I wonder why DAViCal doesn't have that.

Looks like a server issue as well. "text/xml" is ok for *DAV requests.
RFC 4918 explicitly says that "application/xml" is the preferred content
type, but "text/xml" MUST be accepted too. See
https://tools.ietf.org/html/rfc4918#section-8.2

The two issues above are just bugs and should be fixed. You should
create tickets at https://gitlab.com/davical-project/davical

Thanks for pointing out. I'll create tickets.
