Summary - #3229 - @-sign in UID make caldav/lightning not working
Hello,
I try to create an event by importing a ics through thunderbird/lightning. The event get’s created but it does not show up in lightning anymore. I suspect the @ in the filename to be the bad point. I am not sure if egw or lightning is to blame, so also a bug at mozilla is filed.
https://bugzilla.mozilla.org/show_bug.cgi?id=766977
I attached a wireshark log and the ics file.
Lightning is 2.4a2 and egw is uptodate svn 1.8.004.
Thanks
Christoph

Hi Christoph,
checked that with Cadaver:
a) uploaded an ics with an @ sign using nc (netcat):
PUT test@test.ics HTTP/1.1
or
PUT test%40test.ics HTTP/1.1
Both give a test@test.ics caldav_name in database and get urlencoded in PROPFIND (Cadaver ls) requests. First form without urlencoding is strictly speaking not correct, but works also.
b) using a wildcard with GET does not work, because Cadaver sends literally it to WebDAV server, without expanding it first. So it does NOT understand wildcards in GET.
c) using GET test@test.ics works, Cadaver automatically url encodes it in it’s request:
GET /egroupware/groupdav.php/ralf/calendar/test%40test.ics
That’s the correct behavior and file get downloaded successfull.
d) if you use an already url encoded name, Cadaver encodes the percent sign again to test%2540test.ics and download obviously fails.
As far as I can tell EGroupware behaves correct in that regard.

One more comment:
Putting and listing an ics with cadaver; i can see a difference of the file created ‘Bahn%40Fahrplan.ics’ and the result of the ls B* which is ‘Bahn%2540Fahrplan.ics’. Trying to download the filename from the listing, then fails with a 404.
The shell from the cadaver session:
dav:/egroupware/groupdav.php/calendar/> put Bahn@Fahrplan.ics
Uploading Bahn@Fahrplan.ics to /egroupware/groupdav.php/calendar/Bahn%40Fahrplan.ics': Progress: [=============================>] 100,0% of 1243 bytes succeeded. dav:/egroupware/groupdav.php/calendar/> ls Bahn* [Matching... 1 match.] Listing collection/egroupware/groupdav.php/calendar/Bahn%2540Fahrplan.ics/’: collection is empty.

Hi Ralf,
I think the problem is, that lightning constructs a filename from the UID which contains a @ sign.
The file is created in egw, it is there and found by other clients, but not by lightning anymore.
In the query for files I can see the hex description for the @sign, and egw doesn’t deliver the file.
Maybe it is a lightning bug, but I am not sure.
Doing some tries with cadaver the point seems to be if the @ is masked in the get command, I don’t know what is the correct behaviour:
dav:/egroupware/groupdav.php/calendar/> get BAHN@Fahrplan.ics hhhfff.ics
Downloading /egroupware/groupdav.php/calendar/BAHN%40Fahrplan.ics' to hhhfff.ics: Progress: [=============================>] 100,0% of 1380 bytes succeeded. dav:/egroupware/groupdav.php/calendar/> get BAHN%40Fahrplan.ics hhhfff.ics Downloading/egroupware/groupdav.php/calendar/BAHN%2540Fahrplan.ics’ to hhhfff.ics: [.] failed:
404 Not Found

Hi Christoph,
EGroupware does NOT generate UIDs with an @-sign. Our UIDs use following form
–
But you can import ics files or CalDAV clients can add events, which contain arbitrary UIDs.
AFAIK there’s no strong specifiction about format of UIDs.

Just tested with a trunk from yesterday, it doesn’t work here either.
