How to upgrade from the soon-to-be-defunct trac+darcs to the nice new trac-darcs plugin:

Starting out

  1. Bring apache down: 

    /etc/init.d/apache2 stop

  2. Create an install directory 

    cd
mkdir -p install/dtPlugins
cd install

  3. Remove your old trac (otherwise you'll get weird errors like 'module' object has no attribute 'get_cnx_pool'): 

    cd /usr/lib/python-2.3/site-packages
rm -rf trac

  4. Get the latest version of trac! Anything below 0.10 will simply not do 

    svn co http://svn.edgewall.com/repos/trac/trunk trac
cd trac
python setup.py build
python setup.py install
cd ..

  5. Get Lele's plugin: 

    darcs get http://darcs.arstecnica.it/trac-darcs
cd trac-darcs
python setup.py bdist_egg
cp dist/TracDarcs-0.3-py2.3.egg ~/install/dtPlugins
cd ..

For each environment...

  1. cd /var/trac/THE_ENVIRONMENT

  2. copy the egg in 

    cp ~/install/dtPlugins/TracDarcs-0.3-py2.3.egg plugins

  3. edit conf/trac.ini, and replace repository_dir=darcs:/foo with 

    repository_type = darcs
repository_dir = /foo

  4. also in conf/trac.ini, add 

    [components]
trac.versioncontrol.svn_fs.* = disabled
tracdarcs.* = enabled

  5. Upgrade the database: 

    trac-admin . upgrade
trac-admin . resync

Final steps

  1. Say a prayer, knock on wood, etc.

  2. Restart apache: 

    /etc/init.d/apache2 start
