Subversion With Write Over HTTP

To use Subversion with read/write support over the Subversion HTTP protocol, you have to configure the HTTP Subversion backend.

Prerequisites

  • Enable HTTP support inside the admin VCS settings on your RhodeCode Enterprise instance
  • You need to install the following tools on the machine that is running an instance of RhodeCode Enterprise: Apache HTTP Server and mod_dav_svn.

Tip

We recommend using Wandisco repositories which provide latest SVN versions for most platforms. Below is example how to add the wandisco repositories for Ubuntu.

$ sudo sh -c 'echo "deb http://opensource.wandisco.com/ubuntu `lsb_release -cs` svn19" >> /etc/apt/sources.list.d/subversion19.list'
$ sudo wget -q http://opensource.wandisco.com/wandisco-debian.gpg -O- | sudo apt-key add -
$ sudo apt-get update

Using Ubuntu 14.04/16.04 Distribution as an example execute the following to install required components:

$ sudo apt-get install apache2 libapache2-mod-svn

Once installed you need to enable dav_svn:

$ sudo a2enmod dav_svn
$ sudo a2enmod headers
$ sudo a2enmod authn_anon

Configuring Apache Setup

Tip

It is recommended to run Apache on a port other than 80, due to possible conflicts with other HTTP servers like nginx. To do this, set the Listen parameter in the /etc/apache2/ports.conf file, for example Listen 8090.

Warning

Make sure your Apache instance which runs the mod_dav_svn module is only accessible by RhodeCode Enterprise. Otherwise everyone is able to browse the repositories or run subversion operations (checkout/commit/etc.).

It is also recommended to run apache as the same user as RhodeCode Enterprise, otherwise permission issues could occur. To do this edit the /etc/apache2/envvars

export APACHE_RUN_USER=rhodecode
export APACHE_RUN_GROUP=rhodecode
  1. To configure Apache, create and edit a virtual hosts file, for example /etc/apache2/sites-enabled/default.conf. Below is an example how to use one with auto-generated config `mod_dav_svn.conf` from configured RhodeCode Enterprise instance.
<VirtualHost *:8090>
    ServerAdmin rhodecode-admin@localhost
    DocumentRoot /var/www/html
    ErrorLog ${'${APACHE_LOG_DIR}'}/error.log
    CustomLog ${'${APACHE_LOG_DIR}'}/access.log combined
    LogLevel info
    # allows custom host names, prevents 400 errors on checkout
    HttpProtocolOptions Unsafe
    Include /home/user/.rccontrol/enterprise-1/mod_dav_svn.conf
</VirtualHost>
  1. Go to the Admin ‣ Settings ‣ VCS page, and enable Proxy Subversion HTTP requests, and specify the Subversion HTTP Server URL.

  2. Open the RhodeCode Enterprise configuration file, /home/user/.rccontrol/instance-id/rhodecode.ini

  3. Add the following configuration option in the [app:main] section if you don’t have it yet.

    This enables mapping of the created RhodeCode Enterprise repo groups into special Subversion paths. Each time a new repository group is created, the system will update the template file and create new mapping. Apache web server needs to be reloaded to pick up the changes on this file. To do this, simply configure svn.proxy.reload_cmd inside the .ini file. Example configuration:

############################################################
### Subversion proxy support (mod_dav_svn)               ###
### Maps RhodeCode repo groups into SVN paths for Apache ###
############################################################
## Enable or disable the config file generation.
svn.proxy.generate_config = true
## Generate config file with `SVNListParentPath` set to `On`.
svn.proxy.list_parent_path = true
## Set location and file name of generated config file.
svn.proxy.config_file_path = %(here)s/mod_dav_svn.conf
## Used as a prefix to the <Location> block in the generated config file.
## In most cases it should be set to `/`.
svn.proxy.location_root = /
## Command to reload the mod dav svn configuration on change.
## Example: `/etc/init.d/apache2 reload`
svn.proxy.reload_cmd = /etc/init.d/apache2 reload
## If the timeout expires before the reload command finishes, the command will
## be killed. Setting it to zero means no timeout. Defaults to 10 seconds.
#svn.proxy.reload_timeout = 10

This would create a special template file called `mod_dav_svn.conf`. We used that file path in the apache config above inside the Include statement. It’s also possible to manually generate the config from the Admin ‣ Settings ‣ VCS page by clicking a Generate Apache Config button.

  1. Now only things left is to enable svn support, and generate the initial configuration.
    • Select Proxy subversion HTTP requests checkbox
    • Enter http://localhost:8090 into Subversion HTTP Server URL
    • Click the Generate Apache Config button.

This config will be automatically re-generated once an user-groups is added to properly map the additional paths generated.

Using Subversion

Once Subversion has been enabled on your instance, you can use it with the following examples. For more Subversion information, see the Subversion Red Book

# To clone a repository
svn checkout http://my-svn-server.example.com/my-svn-repo

# svn commit
svn commit
