Trac and Subversion in Apache, on Ubuntu

I got tired of developing senderos.net.ar without source control. Yes, I know, I should have done all this before.

Anyway... These are the notes to setup a subversion repository and a trac server (to browse it and to keep an internal wiki for myself).

I am running Kubuntu 8.10.

These instructions are somewhat based on this tutorial and this blog post (and many other pages I read in between).

I am going to create

• a repository in /home/svnrepo,


• trac environment in /home/tracrepo,


• a single project 'senderos' (subprojects as children, then trunk/tags/branches structure)


• reuse my already working apache server


• use single http authentication
  

Create subversion server.

As root:

svnadmin create /home/svnrepo --fs-type fsfs
chown www-data:www-data /home/svnrepo -R      
vim /home/svnrepo/conf/svnserve.conf
   anon-access = none                        
   auth-access = write                       
   password-db = passwd                      
vim /home/svnrepo/conf/passwd                      
   herchu=myPassword

Test: Run svnserve -d , then stop it.

Apache setup for subversion

As root:

apt-get install libapache2-svn
/etc/init.d/apache2 restart
a2enmod dav_svn
sudo vim /etc/apache2/mods-enabled/dav_svn.conf
  <Location /svn>
    DAVsvn
    SVNPath /home/svnrepo
    AuthType Basic
    AuthName "Earthsea Subversion"
    AuthUserFile /etc/apache2/dav_svn.passwd
    require valid-user
  </Location>
htpasswd -cm /etc/apache2/svn_dav.passwd herchu
  New password: xxx
  Re-type new password: xxx
  Adding password for user herchu
/etc/init.d/apache2 restart

Testing subversion

svn info http://localhost/svn
  Authentication realm: <http://localhost:80> Earthsea Subversion
  Password for 'herchu': ....                                  
          ...                                                          
  Repository UUID: aabbccdd-1122-3344-5566-77889900aabb        
  Revision: 0                                                  
  ...                                                          

Upload my already crowded dirs:

From an empty dir: svn import . http://localhost/svn/senderos/web/trunk
From ~/mapsWeb: svn co http://localhost/svn/senderos/web/trunk .
Then svn add of the files I wanted, and svn ci.

Create the Trac server

Partially based on ubuntu howto

apt-get install trac
trac-admin /home/tracrepo initenv
  Project Name [My Project]> senderos
  Database connection string [sqlite:db/trac.db]> sqlite:db/senderos.db
  Repository type [svn]> svn
  Path to repository [/path/to/repos]> /home/svnrepo
sudo chown www-data:www-data /home/tracrepo/ -R

Test trac with manually loaded server

tracd --port 8000 /home/tracrepo

Open http://localhost:8000 and browse your svn repository and see things are working ok...

Run trac from within apache

This is not installed by default, and I need it:

apt-get install libapache2-mod-python
a2enmod python
sudo /etc/init.d/apache2 restart

More testing...

Temporarily add this in sites-enabled/default
<Location /mpinfo>
   SetHandler mod_python
   PythonInterpreter main_interpreter
   PythonHandler mod_python.testhandler
</Location>

and load http://localhost/mpinfo (If it works, remove this config part)

Finally, setup trac:
Add to sites-enabled/default:

<Location /trac>
   SetHandler mod_python
   PythonInterpreter main_interpreter
   PythonHandler trac.web.modpython_frontend
   PythonOption TracEnv /home/tracrepo
   #   PythonOption TracUriRoot /trac
      PythonOption PYTHON_EGG_CACHE /tmp
</Location>

<Location /trac/login>
   AuthType Basic
   AuthName "senderos"
   AuthUserFile /etc/apache2/dav_svn.passwd
   Require valid-user
</Location>

Make sure you restart your browser while restarting apache!! (you will mess with /login and sessions otherwise)

Check if:

• load http://localhost/trac - Check in "browse" button if the svn repository is browsable
  


• try editing a wiki page (requires to be logged in, you must see a "create" button on unexistent wiki pages)
  

good luck!
