Coding

Today I managed to get a few Trac plug-ins working. One of them assesses the relatedness between files (the more often two files are checked in together, the more they are related). The second plug-in gets the difference between two revisions of a file (svn diff) and counts the number of lines that have been changed. This will be needed for our expertise calculations.

Writing the plug-ins hasn't been too hard. I started out by editing some plug-ins on the "trac hacks" website. I used an "if-I-take-this-section-out-does-it-break?" technique to figure out what the code was doing, and to strip it down into the few features that I actually needed, and then added a bunch of my own stuff. I think I know what I'm doing now (maybe).

Also, I've installed Ubuntu on my laptop, and set up Trac and svn on it (this required re-researching all the fixes to the same problems I encountered when installing them at school -- why didn't I write the solutions down!?) Just in case I need it again, I'm going to write down all the things I installed:

• sudo apt-get install python-setuptools


• sudo easy_install Trac


• sudo apt-get install subversion


• sudo apt-get install apache2-utils


• sudo apt-get install python-subversion

And for reference, this is how to set up a repository and trac project:

• Create the repository:
  svnadmin create [repoName]


• Checkout a working copy:
  svn checkout file:///home/.../[repoName] [workingRepoName]


• Setup a trac project:
  trac-admin /home/..../[projectName] initenv


• Setup a user for the project:
  sudo htpasswd -c /home/.../[projectName]/.htpasswd [username]


• Start the tracd:
  tracd -p 8080 --basic-auth=[projectName],/home/.../[projectName]/.htpasswd,/home/.../[projectName]/ /home/.../[projectName]/
