And then I started writing my own ruby script for same purpose but with some addition and modification. Commit Notification Script is that script, you can download and configure it with your SVN post commit hook as follows.

Add following line at the bottom of your post-commit file:

/usr/bin/ruby /var/www/repositories/project/hooks/commit-email.rb "$1"  "$2"

* Please remember to change the path of you commit-email ruby script.

Now open commit-email ruby file and modify the following section according to your requirement:

# You can edit below

# Subject prefix
sub = "[test_project@vinsol]"  # A project 'test_project' is maitained at vinsol

#list of users who will recieve commit notification
recipients = ["bansalakhil30.10@gmail.com", "akhil@vinsol.com"]

# email which will appear in from email field
from_user = "svn-notify@somedomain.com"

# your smtp settings here
ActionMailer::Base.smtp_settings = { :address => 'localhost', :port => 25, :domain => 'domain.com'}

# Do not edit below this line

You are done with that, now onwards whenever someone commits the code, you’ll get the commit notification mail like:

This can be done by using svn hooks. Yes, svn has inbuilt hook functionality like pre-commit, post-commit, post-lock, post-unlock, pre-lock, pre-unlock, start-commit. We’ll use post-commit hook to get notifications.

First of all get a perl script from here http://svn.collab.net/repos/svn/trunk/tools/hook-scripts/commit-email.pl.in and copy it to hooks directory inside your repository directory, lets say /var/www/repos/repository_name/hooks.
Make sure to rename it as commit-email.pl, ofcourse you need perl installed on your server. Now cd to hooks directory inside you repository directory. Rename post-commit.tmpl to post-commit, and chmod 755 to post-commit and commit-email.pl . Now open post-commit in you favorite editor, and put “/usr/bin/perl /var/www/repos/commit-email.pl –from svn-notify@example.com -s ‘SVN commit notification’ ‘$REPOS’ ‘$REV’ user_whom_to_notify@example.com, another_user_to_notify@example.com” at the bottom of that file. Now open commit-email.pl and make changes in configuration section according to your requirement and server, specially svnlook path.

Congrats!, You are done .

Now your server will send email notification to user_whom_to_notify@example.com, another_user_to_notify@example.com whenever someone commits.

**For security reasons, the Subversion repository executes hook scripts with an empty environment that is, no environment variables are set at all, not even $PATH or %PATH%. Because of this, a lot of administrators are baffled when their hook script runs fine by hand,but doesn’t work when run by Subversion. Be sure to explicitly set environment variables in your hook and/or use absolute paths to programs.

It worked for me, Please let me know if it works for you too.
