.. _vcs-server: 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` .. _install-vcs: VCS Server Installation ^^^^^^^^^^^^^^^^^^^^^^^ To install a VCS Server, see :ref:`Installing a VCS server `. .. _config-vcs: Hooking |RCE| to its VCS Server ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ To configure a |RCE| instance to use a VCS server, see :ref:`Configuring the VCS Server connection `. .. _vcs-server-options: |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. .. rst-class:: dl-horizontal \vcs.backends Set a comma-separated list of the |repo| options available from the web interface. The default is ``hg, git, svn``, which is all |repo| types available. \vcs.connection_timeout Set the length of time in seconds that the VCS Server waits for requests to process. After the timeout expires, the request is closed. The default is ``3600``. Set to a higher number if you experience network latency, or timeout issues with very large push/pull requests. \vcs.server.enable Enable or disable the VCS Server. The available options are ``true`` or ``false``. The default is ``true``. \vcs.server Set the host, either hostname or IP Address, and port of the VCS server you wish to run with your |RCM| instance. .. code-block:: ini ################## ### 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: 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-maintain: 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. .. rst-class:: dl-horizontal \beaker.cache.repo_object.type = memorylru Configures the cache to discard the least recently used items. This setting takes the following valid options: * ``memorylru``: The default setting, which removes the least recently used items from the cache. * ``memory``: Runs the VCS Server without clearing the cache. * ``nocache``: Runs the VCS Server without a cache. This will dramatically reduce the VCS Server performance. \beaker.cache.repo_object.max_items = 100 Sets the maximum number of items stored in the cache, before the cache starts to be cleared. As a general rule of thumb, running this value at 120 resulted in a 5GB cache. Running it at 240 resulted in a 9GB cache. Your results will differ based on usage patterns and |repo| sizes. Tweaking this value to run at a fairly constant memory load on your server will help performance. 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 `. .. code-block:: bash $ rccontrol status .. code-block:: vim - 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-config-file: 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`. .. rst-class:: dl-horizontal \host Set the host on which the VCS Server will run. \port Set the port number on which the VCS Server will be available. \locale Set the locale the VCS Server expects. \threadpool_size Set the size of the threadpool used to communicate with the WSGI workers. This should be at least 6 times the number of WSGI worker processes. \timeout Set the timeout for RPC communication in seconds. .. note:: After making changes, you need to restart your VCS Server to pick them up. .. code-block:: ini ################################################################################ # RhodeCode VCSServer - configuration # # # ################################################################################ [DEFAULT] host = 127.0.0.1 port = 9900 locale = en_US.UTF-8 # number of worker threads, this should be set based on a formula threadpool=N*6 # where N is number of RhodeCode Enterprise workers, eg. running 2 instances # 8 gunicorn workers each would be 2 * 8 * 6 = 96, threadpool_size = 96 threadpool_size = 16 timeout = 0 # cache regions, please don't change beaker.cache.regions = repo_object beaker.cache.repo_object.type = memorylru beaker.cache.repo_object.max_items = 1000 # cache auto-expires after N seconds beaker.cache.repo_object.expire = 10 beaker.cache.repo_object.enabled = true ################################ ### LOGGING CONFIGURATION #### ################################ [loggers] keys = root, vcsserver, pyro4, beaker [handlers] keys = console [formatters] keys = generic ############# ## LOGGERS ## ############# [logger_root] level = NOTSET handlers = console [logger_vcsserver] level = DEBUG handlers = qualname = vcsserver propagate = 1 [logger_beaker] level = DEBUG handlers = qualname = beaker propagate = 1 [logger_pyro4] level = DEBUG handlers = qualname = Pyro4 propagate = 1 ############## ## HANDLERS ## ############## [handler_console] class = StreamHandler args = (sys.stderr,) level = DEBUG formatter = generic [handler_file] class = FileHandler args = ('vcsserver.log', 'a',) level = DEBUG formatter = generic [handler_file_rotating] class = logging.handlers.TimedRotatingFileHandler # 'D', 5 - rotate every 5days # you can set 'h', 'midnight' args = ('vcsserver.log', 'D', 5, 10,) level = DEBUG formatter = generic ################ ## FORMATTERS ## ################ [formatter_generic] format = %(asctime)s.%(msecs)03d %(levelname)-5.5s [%(name)s] %(message)s datefmt = %Y-%m-%d %H:%M:%S .. _svn-http: |svn| With Write Over HTTP ^^^^^^^^^^^^^^^^^^^^^^^^^^ To use |svn| with read/write support over the |svn| HTTP protocol, you have to configure the HTTP |svn| backend. Prerequisites ============= - Enable HTTP support inside the admin VCS settings on your |RCE| instance - You need to install the following tools on the machine that is running an instance of |RCE|: ``Apache HTTP Server`` and ``mod_dav_svn``. Using Ubuntu Distribution as an example you can run: .. code-block:: bash $ sudo apt-get install apache2 libapache2-mod-svn Once installed you need to enable ``dav_svn``: .. code-block:: bash $ sudo a2enmod dav_svn $ sudo a2enmod headers 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. 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 |RCE|, otherwise permission issues could occur. To do this edit the ``/etc/apache2/envvars`` .. code-block:: apache export APACHE_RUN_USER=rhodecode export APACHE_RUN_GROUP=rhodecode 1. To configure Apache, create and edit a virtual hosts file, for example :file:`/etc/apache2/sites-available/default.conf`. Below is an example how to use one with auto-generated config ```mod_dav_svn.conf``` from configured |RCE| instance. .. code-block:: apache ServerAdmin rhodecode-admin@localhost DocumentRoot /var/www/html ErrorLog ${'${APACHE_LOG_DIR}'}/error.log CustomLog ${'${APACHE_LOG_DIR}'}/access.log combined Include /home/user/.rccontrol/enterprise-1/mod_dav_svn.conf 2. Go to the :menuselection:`Admin --> Settings --> VCS` page, and enable :guilabel:`Proxy Subversion HTTP requests`, and specify the :guilabel:`Subversion HTTP Server URL`. 3. Open the |RCE| configuration file, :file:`/home/{user}/.rccontrol/{instance-id}/rhodecode.ini` 4. Add the following configuration option in the ``[app:main]`` section if you don't have it yet. This enables mapping of the created |RCE| repo groups into special |svn| 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. It's recommended to add reload into a crontab so the changes can be picked automatically once someone creates a repository group inside RhodeCode. .. code-block:: ini ############################################## ### Subversion proxy support (mod_dav_svn) ### ############################################## ## 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 ## File system path to the directory containing the repositories served by ## RhodeCode. svn.proxy.parent_path_root = /path/to/repo_store ## Used as a prefix to the block in the generated config file. In ## most cases it should be set to `/`. svn.proxy.location_root = / 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. Using |svn| =========== Once |svn| has been enabled on your instance, you can use it with the following examples. For more |svn| information, see the `Subversion Red Book`_ .. code-block:: bash # To clone a repository svn checkout http://my-svn-server.example.com/my-svn-repo # svn commit svn commit .. _Subversion Red Book: http://svnbook.red-bean.com/en/1.7/svn-book.html#svn.ref.svn .. _Ask Ubuntu: http://askubuntu.com/questions/162391/how-do-i-fix-my-locale-issue
