1. Add a new trac setting in /etc/apache2/sites-available/default

2. Copy a template

cp -Rf /var/www/trac/trac-template /var/www/localdumplings

3. Restart Apache2

4. Resync the repository

trac-admin localdumpling resync

[logging]
log_file = trac.log

was that every post was being sent to an SMTP server.

The culprit as you expected was my slow qmail server which for some reason I can’t figure out for now.

Workaround
I have to disable email alerts for every new/update ticket for the time being.

A. A fresh start…
1. Installed Debian. Fixed network and ssh.
2. apt-get install apache2
3. apt-get install subversion
4. apt-get install python python-setuptools python-mysqldb python-subversion
5. apt-get install libapache2-svn libapache2-mod-python

B. Making SVN work…
1. svnadmin create /repos –fs-type fsfs

2. Since I have a fresh apache configuration, I edited it accordingly from /etc/apache2/mods-available/dav_svn.conf:

#SVN dir
<location>
  DAV svn
  SVNPath /repos
  SVNAutoversioning on
  AuthType Basic
  AuthName "SVN - Your Project"
  AuthUserFile /repos/svn-auth-file
  Require valid-user
</location>

3. Restart apache

4. To test if svn is running, import a project inside the repository.
svn import -m "initial import" /tmp/project http://127.0.0.1/repos/project

C. Migrating the data

After I got my fresh debian svn machine, I need to move the svn data and trac to the new server. http://svnbook.red-bean.com/nightly/en/svn.reposadmin.html

1. Transfer /repos/svn-auth-file and /repos/svn-authorization-file to the new server
2. Transferred trac.tar.gz (/var/www/trac) to the new server

To move the svn data from one server to another, I tried the ff choices…
1. svnadmin dump /repos /reposbak. Will work if disk space is not an issue. My /repos is 25 GB, and my other 30 GB partition was wiped out, even though the dump was not finished yet.

2. svnadmin hotcopy --clean-logs /repos /repos2. Accdg to the docs, this is exactly the same repository without the BdB logs. I then transferred the hotcopy from choice 2 above to the new server and works flawlessly to my surprise. So now, I still have all my revisions

http://bealers.com/2008/01/01/installing-trac-on-debian-etch/
http://trac.edgewall.org/wiki/TracOnDebianSarge
http://trac.edgewall.org/wiki/TracUpgrade
http://trac.edgewall.org/wiki/TracInstall
http://trac.edgewall.org/wiki/TracModPython

So, I have to use Trac 0.11, setuptools and Genshi.

Prerequisites:
- Must have python 2.3+
- Must have mod_python-3.3.1.tgz
- Must have httpd2.0.x+ or httpd2.2.x

A. Core Trac Installation

1. Install setuptools-0.6c6-py2.3.egg. Download the setuptools according to your python distribution and simply run:

sh setuptools-0.6c4-py2.3.egg

2. Install Genshi. There are numerous ways of installing Genshi.

easy_install Genshi

or


#wget http://ftp.edgewall.com/pub/genshi/Genshi-0.4.2-py2.3.egg
#chmod +x Genshi-0.4.2-py2.3.egg
#easy_install Genshi-0.4.2-py2.3.egg


3. Install Trac 0.11. We need to install trac from svn
#svn co http://svn.edgewall.org/repos/trac/trunk trac
#python ./setup.py install

This would install trac-admin and tracd in /usr/bin.

Trac Post Intall

#mkdir -p /var/www/trac
#cd /var/www/trac
#trac-admin /var/www/trac/poimgr initenv
#chown -Rf nobody:root /var/www
#chmod -Rf 755 /var/www


Just accept the defaults for now, we can change it later on /var/www/trac/poimgr/conf/trac.ini.

C. Apache Configuration

LoadModule python_module /usr/local/apache2/modules/mod_python.so
 
<location>
SetHandler mod_python
PythonHandler trac.web.modpython_frontend
PythonOption TracEnv /var/www/trac/poimgr
PythonOption TracUriRoot /trac/poimgr
#Order deny,allow
#Deny from all
#Allow from 192.168.1.0/24
AuthType Basic
AuthName "TRAC-POIMGR"
AuthUserFile "/repos/svn-auth-file"
require valid-user
</location>

Notes:
http://www.yolinux.com/TUTORIALS/LinuxSubversionAndTracServer.html

Depending on your installation, you may encounter some problems. I had problems with expat errors:


ExpatError (null): line 1,column 0.


Turns out that it was confused between the link libraries of apache and that of python.

#ps aux | grep http | head -3
#sof -p 29982 | grep expat
# strings libexpat.so.0.1.0 | grep expat_
expat_1.95.2
# strings /usr/lib/python2.3/lib-dynload/pyexpat.so | grep expat_
expat_1.95.7
 
Quickfix is to use symbolic links:
#cd /usr/local/apache2/lib/
#cp -Rf /usr/lib/libexpat.so.0.5.0 /usr/local/apache2/lib/
#ln -s libexpat.so.0.5.0 libexpat.so
#ln -s libexpat.so.0.5.0 libexpat.so.0
#su -l
#/etc/init.d/httpd restart

Configuring Trac.
1. I have to move /etc/svn-auth-file to /repos-auth-file. Change the permissions so “nobody” could access it.

2. How to configure my users? Well, since its an intranet application and my trac-users and developers is both in the svn-auth-file, I need a way to configure users easily. Follow these steps from trac-hack.

easy_install http://trac-hacks.org/svn/accountmanagerplugin/trunk


Role base authorisation in trac

trac-admin /var/www/trac/poiclient permission remove anonymous \
TICKET_CREATE TICKET_MODIFY WIKI_CREATE WIKI_MODIFY
 
for n in rupert andrew; do
trac-admin /var/www/trac/{app_name} permission add $n TRAC_ADMIN
done
 
for n in rupert andrew; do
trac-admin /var/www/trac/{app_name} permission add $n WIKI_DELETE
done
 
trac-admin /var/www/trac/poiclient permission add authenticated \

REPORT_SQL_VIEW REPORT_VIEW ROADMAP_VIEW SEARCH_VIEW \
TICKET_CREATE TICKET_MODIFY TICKET_VIEW TIMELINE_VIEW \
WIKI_CREATE WIKI_MODIFY WIKI_VIEW

3. Here’s my trac.ini. Things to look at is the notification and account-manager.

4. Deleting a Trac Ticket:

# sqlite3 trac.db
delete from ticket_custom where ticket = [ticketID];
delete from ticket_change where ticket = [ticketID];
delete from ticket where id = [ticketID];
