As soon as Gruber pointed out Darwin Calendar Server I felt like I had to check it out. I’ve played with Darwin Streaming Server in the past and love me some Webkit. I was pleasantly suprised to find that Darwin Calendar Server runs on top of Python and Twisted.
So away I went. I checked out the source and began to poke around. I managed to check out the source before the README was added so I did a fair amount of head scratching and wheel spinning, but it turns out that getting up and running is pretty easy: ./run -s
That sets up the server, downloading and building some prereqs as it goes. I already had some prereqs installed system wide so I can’t guarantee that this works, but I’m pretty sure that it has worked for others. I should take a second to qualify that I’m running OS X 10.4 with Python 2.4 installed. From there I copied over the sample config file (cp ./conf/repository-static.xml ./conf/repository-dev.xml) and immediately started troubleshooting SSL errors. First I installed PyOpenSSL and created a self-signed certificate. That yielded a brand new error: OpenSSL.SSL.Error: [('PEM routines', 'PEM_read_bio', 'no start line'), ('SSL routines', 'SSL_CTX_use_PrivateKey_file', 'PEM lib')]
After doing that and getting some guidance from the folks in #collaboration on freenode I decided to hack away at the plist and disable SSL for now (change SSLEnable to false instead of true). From there I could run the server (./run) and bring up a directory listing my pointing to 127.0.0.1:8008.
From there I subscribed to the example payday calendar and the holiday calendar. It appears that iCal won’t do two-way CalDAV until Leopard, but in the meantime I was able to successfully set up and test Chandler.
This is some absolutely amazing tech in its infancy. I can’t wait to see where this goes and I’m excited that it’s built with tools that I’m familiar with (Python, Twisted, SQLite, iCal). It seems to me like this open source app is but the tip of the iceberg of collaboration features that will be baked in to OS X 10.5 desktop and server. I would also kill for a mobile device that spoke CalDAV natively so that I can replace my duct taped google calendar to iCal to iSync to 6682 workflow.

Matt,
Does the server produce a web-based interactive calendar interface, or does the current version simply serve files?
Thanks,
Alex
Alex,
Darwin Calender server appears to be the backend service. It looks like Apple will provide an online calendar and other groupware features as part of 10.5 Server but my guess is that the apps further up the stack will not be open source.
Matt,
Foudn out that the CRT needs to be a real one. I think if you may code dive, there may be some CA dependencies. I used a real “wildcard” CRT I had purchased and it starts up fine. However, your tips pointed me in the right direction (damn pyton errors!) ;-D

Extraordinary posting & Fantastic blogging site! I would definitely love to begin a site too but I have no clue where to begin. I possess the ability to do it (not that challenging on the technical part) but I really feel like I am too lazy to publish regularly. That is the problem, if you start you could have to go all the way. However blogs like yours inspire me to have a go at it.
