Apache Subversion is an open source version control system. It supports atomic commits, allows arbitrary metadata to be attached to files and includes branching, tagging and merge tracking support.

How to configure basic authentication for your repository?

Once your repository is accessible over HTTP(s), it is recommended that you protect it from unauthorized access by configuring authentication for different users. To do this, follow the steps below:

  • Update the Apache configuration file at /opt/bitnami/apache2/conf/httpd.conf and add the highlighted directives below.

     <Location /subversion>
      DAV svn
      SVNPath "/opt/bitnami/repository"
      AuthType Basic
      AuthName "Subversion repository"
      AuthUserFile /opt/bitnami/repository/users
      require valid-user
     </Location>
    

    With this configuration, repository access is only available to those users listed in the /opt/bitnami/repository/users file and they will need to authenticate themselves before gaining access. Note that you should update the path to the file based on the actual location of your repository.

  • Create the /opt/bitnami/repository/users file and add a user account named myuser to it using the following command. You will be prompted to enter a password for the user account. Note that you should update the path to the file based on the actual location of your repository.

     $ sudo /opt/bitnami/apache2/bin/htpasswd -c /opt/bitnami/repository/users myuser
    
  • Repeat this step to add more users, omitting the -c argument on subsequent invocations. For example:

     $ sudo /opt/bitnami/apache2/bin/htpasswd /opt/bitnami/repository/users myotheruser
    
  • Restart the Apache server.

     $ sudo /opt/bitnami/ctlscript.sh restart apache
    

If you now attempt to browse to the repository or access it using TortoiseSVN, you will be prompted for a user name and password, as shown below:

TortoiseSVN client access

Anonymous browsing

If you want your repository readable but not editable by any other user, perform the steps above but changing the line

require valid-user

to

<LimitExcept GET PROPFIND OPTIONS REPORT>
    require valid-user
</LimitExcept>

HTTPS access only

If you only want to only allow access through HTTPS, not HTTP, you should add SSLRequireSSL to the directives described above:

  ...
  AuthName "Subversion repository"
  AuthUserFile /opt/bitnami/repository/users
  require valid-user
  SSLRequireSSL
</Location>

How to enable post-commit notifications via email for Subversion?

To configure a Subversion repository to send emails via SMTP with the commit log, follow these steps:

  • Download the latest source code from Subversion and copy the hooks directory into the /opt/bitnami/subversion directory:

     $ wget  http://apache.mesi.com.ar/subversion/subversion-1.8.9.tar.gz
     $ tar -xzvf subversion-1.8.9.tar.gz
     $ sudo cp -r subversion-1.8.9/tools/hook-scripts /opt/bitnami/subversion/hooks
    
  • Copy the example mailer.conf file:

     $ sudo cp /opt/bitnami/subversion/hooks/mailer/mailer.conf.example /opt/bitnami/subversion/hooks/mailer/mailer.conf
    
  • Configure the SMTP mail settings in the mailer.conf file. Here is an example for a Gmail account:

     [General]
     smtp_hostname = smtp.gmail.com:465
     smtp_username = your_gmail_account
     smtp_password = your_password
     smtp_use_ssl = true
    
     ...
    
     [defaults]
     from_addr = mail@example.com
    
     # The default To: addresses for message.  One or more addresses,
     # separated by whitespace (no commas).
     # NOTE: If you want to use a different character for separating the
     #       addresses put it in front of the addresses included in square
     #       brackets '[ ]'.
     to_addr = mail@example.com
    
     # If this is set, then a Reply-To: will be inserted into the message.
     reply_to = mail@example.com
    
  • Configure your post-commit hook script to use the mailer.py and mailer.conf files. The location of your post-commit script depends on the location of your repository. Edit the /opt/bitnami/repositories/REPOSITORY-NAME/hooks/post-commit.tmpl file and replace the last line with the following one:

     /opt/bitnami/python/bin/python /opt/bitnami/subversion/hooks/mailer/mailer.py commit "$REPOS" "$REV" /opt/bitnami/subversion/hooks/mailer/mailer.conf
    

    In case the /opt/bitnami/python directory does not exist, use the system's Python binary, usually at /usr/bin/python.

  • Enable the post-commit hook by renaming the post-commit script and removing the .tmpl extension:

     $ sudo mv /opt/bitnami/repositories/your_repo/hooks/post-commit.tmpl /opt/bitnami/repositories/your_repo/hooks/post-commit
    

To test it, change a file and commit the changes. In case of an error, the error message will be displayed after the commit.

How to configure the repository URL?

If no prefix is set in the Subversion scripts, specify the full path to the repository - for instance, svn://SERVER-IP/home/user/repository. In case this is not possible, add the repository path to the Subversion control script.

  • Edit the file /opt/bitnami/subversion/scripts/ctl.sh and add the path as follows:

     -d --listen-port=3690 --root=/path/to/repository
    
  • Restart the Subversion server.

How to configure your Subversion repository though SSH?

To create a repository that allows access remotely over SSH, follow these steps:

  • Connect to your server via SSH and execute the following commands to create the repositories directory at /opt/bitnami/repositories and then a new Subversion repository named myapp:

     $ sudo mkdir /opt/bitnami/repositories
     $ sudo svnadmin create /opt/bitnami/repositories/myapp
     $ sudo chown -R bitnami:bitnami /opt/bitnami/repositories
    
  • Assign your repository to a Redmine project. In Redmine, navigate to the project "Settings -> Repository" menu and add the following value in the "URL" field (username and password are not necessary):

     file:///opt/bitnami/repositories/myapp
    
  • Check if you have Subversion binaries in the system path even in the non-interactive SSH session. Execute the following command:

     $ ssh -l bitnami -i KEYFILE SERVER-IP svn
    

    Remember to replace KEYFILE in the previous commands with the path to your private key file, and SERVER-IP with the public IP address or hostname of your server.

    If you receive a "Command not found" error, update the /home/bitnami/.bashrc file and move all Bitnami path configuration from the bottom of this file to the top, above this line

     [ -z "$PS1" ] && return
    
  • Check out the repository now and start adding and committing new files. The repository should be available remotely via the following URL. The Subversion client should be configured to use the username bitnami and corresponding SSH key:

     svn+ssh://xyz.bitnamiapp.com/opt/bitnami/repositories/myapp
    

    Remember to replace xyz.bitnamiapp.com with the public IP address or hostname of your server.

  • To add a file to your repository, execute the following commands on your local host. Remember to replace bitnami-hosting.pem in the previous commands with the path to your private key file, and xyz.bitnamiapp.com with the public IP address or hostname of your server.

     $ export SVN_SSH="ssh -l bitnami -i bitnami-hosting.pem"
     $ svn checkout svn+ssh://xyz.bitnamiapp.com/opt/bitnami/repositories/myapp
     $ cd myapp
     $ echo "This is a simple test" > Readme.txt
     $ svn add Readme.txt
     $ svn commit -m "Adding simple readme file, closes #1"
    

How to see the Subversion repository from the web browser?

To browse the Subversion repository using a Web browser, follow the steps below:

  • Update the Apache configuration file at /opt/bitnami/apache2/conf/httpd.conf to load the following modules:

     LoadModule dav_module modules/mod_dav.so
     LoadModule dav_fs_module modules/mod_dav_fs.so
     LoadModule dav_svn_module modules/mod_dav_svn.so
     LoadModule authz_svn_module modules/mod_authz_svn.so
    
  • In the same file, verify the endpoint URL and path for your Subversion repository. For example, the directives below will let you view the default repository at /opt/bitnami/repository by browsing to http://SERVER-IP/repository.

     <Location /subversion>
       DAV svn 
       SVNPath "/opt/bitnami/repository"
     </Location>
    
  • Restart Apache:

     $ sudo /opt/bitnami/ctlscript.sh restart apache
    

You should now be able to checkout the repository using a tool like TortoiseSVN. Simply enter the URL as http://SERVER-IP/repository as the repository checkout URL in the TortoiseSVN interface, as shown below.

TortoiseSVN client access

Enabling access over HTTPS

You can also access the repository over HTTPS if you have configured the Apache SSL certificate for your server. The following error can occur if the hostname reported by the server does not match the hostname in the SSL certificate. Make sure your server configuration uses the correct ServerName value.

svn: OPTIONS of 'https://example.com/repository': SSL negotiation failed: SSL error code -1/1/336032856 (https://example.com)

Enabling commits over HTTP(S)

For security reasons, the default configuration does not allow users to commit changes to the repositories over HTTP or HTTPS. To permit this, change the permissions of your repository directory so that the Apache user is able to write to it.

Run the following command, assuming your repository is located at the default location of /opt/bitnami/repository:

$ sudo chown -R daemon:subversion /opt/bitnami/repository
IMPORTANT: Making this change will allow any user to commit changes to your repository. To avoid unauthorized commits and possible data loss, configure basic authentication for your repository as discussed in the next section

You should now be able to commit changes to the repository using a tool like TortoiseSVN, as shown below.
