Future Builds and deployment
by Rick Davis 28 Nov '06

This is my first stroll through Open Source, so please forgive my ignorance. I have things working close to the way I want them to work, well except for having a calendar that multiple users can add events to. I think that is a "wait for iCal on Leopard" issue. Of course that may all change when the users start reporting problems or feature requests. ;-) My question is about the location of the calendars and principals. Should they stay in the current test location inside of the twistedcaldav directory or be moved to the location indicated in the caldavd.plist (as opposed to the caldavd-dev.plist). If I deploy this to a server with the current locations will the next or any future builds retain that location or move things as needed? I'm hoping to deploy this at a school for use by 40+ teachers and staff and eventually open it up to the 900+ students. Thanks and Have A Great Day. Rick Davis thePRIMAXgroup http://applehelp.org

is python 2.5 supported?
by michael dunston 27 Nov '06

27 Nov '06

I'm trying to install Calendar Server on an OSXS 10.4 system, which only has python 2.3. The current python is 2.5 though, so I was wondering if this should work as well as (the recommended) python 2.4. I'm getting the following error when running './run -s' and am wondering in this newer python might be the problem: Dependencies/zope.interface-ZopeInterface-3.1.0c1/zope.interface/ _zope_interface_coptimizations.c:550: error: parse error before ')' token lipo: can't figure out the architecture type of: /var/tmp//cc3wawXQ.out error: command 'gcc' failed with exit status 1 Thanks in advance for any insight. -- -- Michael Dunston -- Music and Technology -- <http://www.music.vt.edu/> -- Virginia Tech Department of Music -- -- -- -- -- -- -- -- -- -- -- --

Problems on FreeBSD, possibly property-related
by Ryan Rempel 03 Nov '06

I've been trying to get CalendarServer to run on FreeBSD, and have been partly successful with a few tweaks to the kerberos headers. However, it's not quite working (or, at least, I think it's not), and I'm wondering if anyone can help point me in the right direction. Here's the output when I start the server: Unknown option: EventExpirationDays 2006/10/31 18:16 -0500 [-] Log opened. 2006/10/31 18:16 -0500 [-] twistd 2.4.0+r18545 (/usr/local/bin/python 2.4.3) starting up 2006/10/31 18:16 -0500 [-] reactor class: <class ' twisted.internet.selectreactor.SelectReactor'> 2006/10/31 18:16 -0500 [-] Loading /tmp/caldavpSmEK0... 2006/10/31 18:16 -0500 [-] Document root is: twistedcaldav/test/data/ 2006/10/31 18:16 -0500 [-] Repository configuration is: conf/repository- dev.xml 2006/10/31 18:16 -0500 [-] Using SSL private key file: conf/server.pem 2006/10/31 18:16 -0500 [-] Using SSL certificate file: conf/server.pem 2006/10/31 18:16 -0500 [-] IMPORTANT: plain text passwords are allowed without an encrypted/secure connection. 2006/10/31 18:16 -0500 [-] Using property-based password checker. 2006/10/31 18:16 -0500 [-] Using HTTP BASIC authentication. 2006/10/31 18:16 -0500 [-] Starting http server 2006/10/31 18:16 -0500 [-] Starting https server 2006/10/31 18:16 -0500 [-] Starting manhole on port 8007 2006/10/31 18:16 -0500 [-] /home/admin/calendar/Twisted/twisted/manhole/telnet.py:8: exceptions.DeprecationWarning: As of Twisted 2.1, twisted.protocols.telnetis deprecated.

For instance, if I try to fetch /calendars/users/user01, then it will not accept my username/password (whether admin/admin or user01/user01). What I see on the sever is: 2006/10/31 18:30 -0500 [HTTPChannel,2,24.77.30.155] GET /calendars/users/user01/ HTTP/1.1 2006/10/31 18:30 -0500 [HTTPChannel,2,24.77.30.155] DAV:principal-collection-set property cannot be found on the resource being authorized: <CalendarHomeFile: /usr/home/admin/calendar/CalendarServer/twistedcaldav/test/data/calendars/users/user01> 2006/10/31 18:30 -0500 [HTTPChannel,2,24.77.30.155] 'Invalid authentication details: <GET /calendars/users/user01/ (1, 1)>' I noted the error message about properties. If I look at the file in the filesystem with lsextattr, I can see that is has the following attribute: WebDAV:{DAV:}acl -- which I assume is a mangled form of DAV:acl. (Not sure where the mangling comes from or whether that might be a problem). The content of the attribute is as follows (as seen from getextattr): <?xml version='1.0' encoding='UTF-8'?> <acl xmlns='DAV:'> <ace> <principal> <authenticated/> </principal> <grant> <privilege> <read/> </privilege> </grant> </ace> <ace> <principal> <href>/principals/users/user01</href> </principal> <grant> <privilege> <all/> </privilege> </grant> <inheritable xmlns='http://twistedmatrix.com/xml_namespace/dav/'/> </ace> </acl> So, clearly something is setting the attribute -- modulo the name mangling. However, it is true that there is no DAV:principal-collection-set property there. Going up the hierarchy, there is WebDAV:{DAV:}principal-collection-set property on calendar/CalendarServer/twistedcaldav/test/data (as seen with lsextattr -- again, I'm assuming that there is some name-mangling going on here which may or may not be the problem). The content of the attribute (as seen with getextattr) is as follows: <?xml version='1.0' encoding='UTF-8'?> <principal-collection-set xmlns='DAV:'> <href>/principals/users/</href> </principal-collection-set> I haven't set this up on Mac OS X, so I don't know what I'm supposed to be seeing. If anyone can give me a few clues, I would be most grateful. My working assumption is that the names of the properties are being mangled when written in some way that is causing problems when they are read.

Can't get past Checking out Twisted....
by Thiessen Mark 27 Oct '06

27 Oct '06

The run script stops at the message below when I do ./run -s Checking out Twisted... subversion/libsvn_ra_svn/client.c:141: (apr_err=60) svn: Can't connect to host 'svn.twistedmatrix.com': Operation timed out if I retry the run script it get the same thing. I've looked at the run script and can point my web browser to the path specified. Not sure what the problem is unless twistedmatrix.com has their SVN turned off. Is that possible? I'm new to the SVN thing. Mark Thiessen Staff Photographer National Geographic Magazine 1145 17th Street, NW Washington, DC 20036 202-857-7042 mthiesse(a)ngs.org
