== Trac (interface to Subversion and integrated wiki) and SVN (subversion) ==

Trac is an enhanced wiki and issue tracking system for software development projects. It provides a Graphical front end to SVN where diffs in files can be obtained. It '''cannot''' update the SVN repository. It simply provides a Project Management interface, wiki, ticketing system, and SVN front end.

SVN is a free/open-source '''Version Control System'''. Subversion (SVN) manages files and directories over time. Files are placed into a central repository and every change every made to the files or directories are remembered.
If you are not familiar with SVN - then the following PDF document is a DEFINATE MUST:  http://svnbook.red-bean.com/ 

=== Install SVN + Trac Software on Debian Sarge / SID ===
 apt-get install apache2
 apt-get install subversion
 apt-get install libapache2-svn
 apt-get install trac

=== Get SVN Working ===
 mkdir /var/lib/svn
 mkdir /var/lib/svn/projectname
 svnadmin create /var/lib/svn/projectname --fs-type fsfs
 chown -R www-data /var/lib/svn/projectname 
 chgrp -R www-data /var/lib/svn/projectname 

In order to keep all SVN + apache2 configs together the following steps were carried out:
 mkdir /etc/apache2/svn
 vi /etc/apache2/apache2.conf
                              #Include Configs for Svn:
                              Include /etc/apache2/svn/[^.#]*
 vi /etc/apache2/svn/projectname
                              <Location /svn/projectname>
                              DAV svn
                              SVNPath /var/lib/svn/projectname
                              
                              AuthType Basic
                              AuthName "Subversion Repository - Projectname"
                              AuthUserFile /etc/apache2/svn/.htpasswd
                              
                              <LimitExcept GET PROPFIND OPTIONS REPORT>
                                      Require valid-user
                                      SSLRequireSSL
                              </LimitExcept>
                              </Location>
 htpasswd2 -c .htpasswd username
SVN should be all working now. If you go to http://host/svn/projectname you should see all there.

=== Get TRAC Working ===
It is best if trac is installed into a User's home directory, e.g. /home/user
 trac-admin /home/user/projectname initenv
 //enter data for the title
 //enter data for the sql-lite database (choose defaults)
 //enter path to svn info ( /var/lib/svn/projectname )
 //enter path to Trac template (choose default)
 
 trac-admin /home/username/projectname/ permission add username MILESTONE_ADMIN REPORT_ADMIN ROADMAP_ADMIN TICKET_ADMIN TRAC_ADMIN
 //should work fine.
 
 chmod -R username:group /home/username/projectname
 chgrp -R www-data /home/username/projectname/db
 chmod -R 775 /home/username/projectname/db
 
 mkdir -p /home/username/public_html/projectname
 vi /home/username/public_html/projectname/.htaccess   //not necessary, but useful for images/downloads etc.
 
 vi /etc/apache2/svn/projectname   //add the content below it the end.
                                                      ScriptAlias /~username/projectname /usr/share/trac/cgi-bin/trac.cgi
                                                      <Location "/~username/projectname">
                                                      SetEnv TRAC_ENV "/home/username/projectname"
                                                      </Location>
                                                      
                                                      <Location "/~username/projectname/login">
                                                      SSLRequireSSL                                                      
                                                      AuthType Basic
                                                      AuthName "Trac Login for Projectname Website"
                                                      AuthUserFile /etc/apache2/svn/.htpasswd
                                                      Require valid-user
                                                      </Location>

=== Delete a TRAC & SVN Account ===

Things to delete:
 rm -R /var/lib/svn/projectname
 rm /etc/apache2/svn/projectname
 rm -R /home/username/projectname
 rm -R /home/username/public_html/projectname //if exists

=== Add a TRAC & SVN Account ===
Sorry if this repetitive of above.
 svnadmin create /var/lib/svn/projectname --fs-type fsfs
 chown -R www-data:www-data /var/lib/svn/projectname 
 trac-admin /home/user/projectname initenv
 trac-admin /home/username/projectname/ permission add username MILESTONE_ADMIN REPORT_ADMIN ROADMAP_ADMIN TICKET_ADMIN TRAC_ADMIN
 chown -R username:group /home/username/projectname
 chgrp -R www-data /home/username/projectname/db
 chmod -R 775 /home/username/projectname/db

 vi /etc/apache2/svn/projectname
 <Location /svn/projectname>
 DAV svn
 SVNPath /var/lib/svn/projectname 
 
 AuthType Basic
 AuthName "Subversion Repository - Projectname"
 AuthUserFile /etc/apache2/svn/.htpasswd
 
 <LimitExcept GET PROPFIND OPTIONS REPORT>
         Require valid-user
         SSLRequireSSL
 </LimitExcept>
 </Location>
 
 ScriptAlias /~username/projectname /usr/share/trac/cgi-bin/trac.cgi
 <Location "/~username/projectname">
 SetEnv TRAC_ENV "/home/username/projectname"
 </Location>
 
 <Location "/~username/projectname/login">
 SSLRequireSSL                                                      
 AuthType Basic
 AuthName "Trac Login for Projectname Website"
 AuthUserFile /etc/apache2/svn/.htpasswd
 Require valid-user

 /etc/init.d/apache2 restart

=== Wipe a SVN repo and update Trac ===
If you want to wipe a svn repo - if it got corrupt or if something happened, AND you want to keep trac etc. you need to do the following:
 rm /var/lib/svn/projectname
 /var/lib/svn/projectname
 //chown and reset permissions as covered previously
Trac then will give the following error: "The 'repository_dir' has changed, a 'trac-admin resync' operation is needed". Here is what to do:
 trac-admin /home/username/projectname resync
Hope that works ok for you. Info: http://trac.edgewall.org/ticket/4204

== Errors and Problems with Trac ==
After upgrading python2.3 to python2.4 (among other things) on the compsoc server, trac got itself broken. The errors I was getting were:
"file is encrypted or is not a database" and "clearsilver not installed etc."

1. Check that:
 /usr/bin/python is symlinked to: python2.4

2. Check that sqlite is installed. It is quite possible that only sqlite3 is installed, hence giving the above problems.
3. This might solve some issues. If it doesnt:
 cd /project/trac/db
 cd  /var/site/nara.ms/project/hoge/trac
 mv trac.db trac2.db
 sqlite trac2.db  .dump | sqlite3 trac.db
 trac-admin trac upgrade
 trac-admin trac resync
