VCS Server Management
The VCS Server handles |RCM| backend functionality. You need to configure a VCS Server to run with a |RCM| instance. If you do not, you will be missing the connection between |RCM| and its |repos|. This will cause error messages on the web interface. You can run your setup in the following configurations, currently the best performance is one VCS Server per |RCM| instance:
- One VCS Server per |RCM| instance.
- One VCS Server handling multiple instances.
Important
If your server locale settings are not correctly configured, |RCE| and the VCS Server can run into issues. See this Ask Ubuntu post which explains the problem and gives a solution.
For more information, see the following sections:
- :ref:`install-vcs`
- :ref:`config-vcs`
- :ref:`vcs-server-options`
- :ref:`vcs-server-versions`
- :ref:`vcs-server-maintain`
- :ref:`vcs-server-config-file`
- :ref:`svn-http`
VCS Server Installation
To install a VCS Server, see :ref:`Installing a VCS server <control:install-vcsserver>`.
Hooking |RCE| to its VCS Server
To configure a |RCE| instance to use a VCS server, see :ref:`Configuring the VCS Server connection <control:manually-vcsserver-ini>`.
|RCE| VCS Server Options
The following list shows the available options on the |RCM| side of the connection to the VCS Server. The settings are configured per instance in the :file:`/home/{user}/.rccontrol/{instance-id}/rhodecode.ini` file.
################## ### VCS CONFIG ### ################## # set this line to match your VCS Server vcs.server = 127.0.0.1:10004 # Set to False to disable the VCS Server vcs.server.enable = True vcs.backends = hg, git, svn vcs.connection_timeout = 3600
VCS Server Versions
An updated version of the VCS Server is released with each |RCE| version. Use the VCS Server number that matches with the |RCE| version to pair the appropriate ones together. For |RCE| versions pre 3.3.0, VCS Server 1.X.Y works with |RCE| 3.X.Y, for example:
- VCS Server 1.0.0 works with |RCE| 3.0.0
- VCS Server 1.2.2 works with |RCE| 3.2.2
For |RCE| versions post 3.3.0, the VCS Server and |RCE| version numbers match, for example:
- VCS Server |release| works with |RCE| |release|
VCS Server Memory Optimization
To configure the VCS server to manage the cache efficiently, you need to configure the following options in the :file:`/home/{user}/.rccontrol/{vcsserver-id}/vcsserver.ini` file. Once configured, restart the VCS Server.
To clear the cache completely, you can restart the VCS Server.
Important
While the VCS Server handles a restart gracefully on the web interface, it will drop connections during push/pull requests. So it is recommended you only perform this when there is very little traffic on the instance.
Use the following example to restart your VCS Server, for full details see the :ref:`RhodeCode Control CLI <control:rcc-cli>`.
$ rccontrol status
- NAME: vcsserver-1 - STATUS: RUNNING - TYPE: VCSServer - VERSION: 1.0.0 - URL: http://127.0.0.1:10001 $ rccontrol restart vcsserver-1 Instance "vcsserver-1" successfully stopped. Instance "vcsserver-1" successfully started.
VCS Server Configuration
You can configure settings for multiple VCS Servers on your system using their individual configuration files. Use the following properties inside the configuration file to set up your system. The default location is :file:`home/{user}/.rccontrol/{vcsserver-id}/vcsserver.ini`. For a more detailed explanation of the logger levers, see :ref:`debug-mode`.
Note
After making changes, you need to restart your VCS Server to pick them up.
