CollabNet Subversion Edge cont'd

I already explained Collabnet Subversion Edge and my experience installing it. Now I want to focus on installing Trac (with some hacks).
I really thought this should be easy, but it turns out that there are a lot of pitfalls. So for any other poor souls who are not fluent in python (and for my own reference) here it goes.

Installing Trac

As you know, trac has some requirements. Namely setuptools and genshii. There are a few packages to download for Windows here. I didn't know which version of python came with subversion edge, so I checked. There is a folder named csvn/python25. So it seems to be python 2.5. But wait - there is a python27.dll in there. and some other files indicating python 2.7. So which is it?

D:\csvn\Python25>python.exe --version
Python 2.7.1

 Alright, that settles it. But why did Collabnet not rename the folder..?
So I downloaded the setuptools package for python 2.7 and win32. The installer failed to run, it sais it couldn't find any python 2.7 installation.

Apparently a regular python installer will create some registry entries so that the system recognizes the python installation. Collabnet subversion edge doesn't do this anymore due some complaints.
So I had to go in there and manually create the relevant entries. They were already present from the old python 2.5 installation, which I wanted to get rid of anyway. So I changed the version to 2.7 and updated the paths to point to D:\csvn\python25. This let me install setuptools, genshii and finally trac too.

Configuring Trac

That part was straight-forward. Like with subversion, I just copied the relevant parts of my VisualSVN server's apache config and pasted it to the main httpd.conf file. Here is the relevant snippet:

<Location /trac>
 SetHandler mod_python
 PythonInterpreter main_interpreter
 PythonHandler trac.web.modpython_frontend
 PythonOption TracEnvParentDir D:\Trac
 PythonOption TracUriRoot /trac

 AuthName "Trac"
 AuthType SSPI
 SSPIAuth On
 SSPIAuthoritative On
 SSPIDomain jerich
 SSPIOfferBasic On
 SSPIOmitDomain On
 require group DOMAIN\Trac-Users
</Location>

All relevant modules are already loaded, so that's it.

Collabnet Subversion Edge

I have been quite fond of VisualSVN Server on Windows, since it was an easy way to setup subversion with a nice means to administer repositories and users.

As of lately, I grew tired because of the way they mangled apache, subversion, python and trac together. While searching for an alternative I found out that Collabnet offers exactly what I need: Apache bundled with Subversion, Python and other stuff. Very nice! This bundle is called Subversion Edge.

I decided to take the plunge and update the production VisualSVN server. After all: How hard can it be?

The installation went fine, and the collabnet subversion edge web-interface greeted me.
I had tweaked the configuration of VisualSVN server to allow single-sign-on with SSPI, so I naturally wanted to copy the relevant parts of the config. Once one tinkers with the config files, the web-interface can no longer be used to make changes to those parts. That's fine by me.

After this was taken care of I fired up Collabnet's Apache service and started to dump my subversion repositories one by one. Instead of manually loading them with svnadmin, the web interface of subversion edge provides takes care of that. Simply point it to the dump file and go ahead. That was easy!

Setting up the server, finetuning apache and migrating my three repositories took less than one hour! ;-)
