Add SVN email notification

SVN email notification is important when many programmer involves  in software development. For example, you are working on module and other programmers are using that. So if you check-in updated the classes , you have to notify other developers that module has been updated.

SVN provide post commit hook option, there you can add any script or programme that would be execute after SVN commit. Here I will add email notification in post-commit hook script.

I have create a repository in /apps/subversion/hsolite/.
Using ls command you can see default directories created under repository. There is a directory called hooks where you will put you post-commit script. When any user will commit in SVN, post-commit script will be execute.

To send email notification you need find out "mailer.py" and "mailer.conf"

[root@domU-12-31-39-09-29-13 hsolite]# find / -name "mailer.py"
/usr/share/doc/subversion-1.6.11/tools/hook-scripts/mailer/mailer.py

[root@domU-12-31-39-09-29-13 hsolite]#  find / -name "mailer.conf"

/usr/share/doc/subversion-1.6.11/tools/hook-scripts/mailer/tests/mailer.conf

Now copy the mailer.py and mailer.conf  under /apps/subversion/hsolite/hooks and  /apps/subversion/hsolite/ respectively.

[root@domU-12-31-39-09-29-13 hsolite]#  cp /usr/share/doc/subversion-1.6.11/tools/hook-scripts/mailer/mailer.py   /apps/subversion/hsolite/hooks/mailer.py

[root@domU-12-31-39-09-29-13 hsolite]# cp  /usr/share/doc/subversion-1.6.11/tools/hook-scripts/mailer/tests/mailer.conf   /apps/subversion/hsolite//mailer.conf

Now edit the mailer.conf and override following properties

mail_command = /usr/sbin/sendmail

commit_subject_prefix = [svn-myproject]

from_addr = noreply@mydomain.com

to_addr = commits-myproject@mydomain.com  # this is a mailing list

Under hooks directory you will find "post-commit.tmpl" that you need to rename to "post-commit".

Replace "post-commit" script  contains with the following snippet.

------------------------------------------------

#!/bin/sh

REPOS="$1"

REV="$2"

/apps/subversion/hsolite/hooks/mailer.py commit "$REPOS" "$REV" /apps/subversion/hsolite/mailer.conf

-------------------------------------------------------

Make sure "post-commit" is executable.

[root@domU-12-31-39-09-29-13 hsolite]# chmod +x post-commit

Testing :

Using svnlook  yon can get latest revision number.

[root@domU-12-31-39-09-29-13 ~]# svnlook info /apps/subversion/hsolite/

[root@domU-12-31-39-09-29-13 ~]# svnlook youngest /apps/subversion/hsolite/

2850

Test the hook script:

[root@domU-12-31-39-09-29-13 ~]# REPOS=/apps/subversion/hsolite/

[root@domU-12-31-39-09-29-13 ~]#  REV=2850

[root@domU-12-31-39-09-29-13 ~]#  "$REPOS"/hooks/mailer.py commit "$REPOS" $REV "$REPOS"/mailer.conf 

After run above command you should receive email notification with revision number 2850

[root@domU-12-31-39-09-29-13 ~]# REPOS=/apps/subversion/hsolite/
[root@domU-12-31-39-09-29-13 ~]#  REV=2850
[root@domU-12-31-39-09-29-13 ~]#   sh $REPOS/hooks/post-commit  $REPOS$REV

If post-commit script run successfully then commit some files in SVN then check your email inbox for notification.
