Subversion on Lintula and TST computers

This page contains some information on using a revision control system called Subversion on Lintula and TST computers. This is just brief instructions about where to put the Subversion repository, how to create and access the repository and how to use Subversion with a course account. General instructions about Subversion can be found for example at http://svnbook.red-bean.com/. There are also Finnish instructions on how to use Subversion on TUT Software systems courses at http://www.cs.tut.fi/~ohjtuki/svn/.

Repository location

The repository should always be located on redundant disk space that is automatically backed up in a regular fashion.

More information about disk space on Lintula computers.

Repository location for personal projects

For personal projects, the best place for the repository is probably the users home directory (if the size of the repository is small) or department personnel directory /share/XXXusers/<username>.

Creating a repository for a project

The repository for a non-personal project should be accessible by all project members, i.e. all users in the course accounts group. The repository should be located in project directory, the repository directory and all files and directories under that should have the course account as a group owner and should be group writable.

Example on how to create a repository in a directory called /share/XXXprojects/tproject/repository/ that will be owned by a course account called tproject:

hopeatilhi:~$ mkdir /share/XXXprojects/tproject/repository

hopeatilhi:~$ chgrp tproject /share/XXXprojects/tproject/repository

hopeatilhi:~$ chmod u=rwx,g=rwx,g+s,o= /share/XXXprojects/tproject/repository

hopeatilhi:~$ umask 007

hopeatilhi:~$ svnadmin create --fs-type fsfs /share/XXXprojects/tproject/repository

hopeatilhi:~$ chmod g+w /share/XXXprojects/tproject/repository/db/rep-cache.db

Checking out and accessing the repository with a Lintula workstation or ssh-server

The repository located in a shared directory (for example directories under /share/ or /home/ directories) can be accessed through the filesystem (ie. with file:// prefix) on Lintula workstations and ssh servers. For example:

hopeatilhi:~$ svn ls file:///share/XXXprojects/tproject/repository

hopeatilhi:~$ svn checkout file:///share/XXXprojects/tproject/repository

Checking out and accessing the repository from some other computer (and for example Lintula Linux Laptop or Lintula Webhotel virtual machines)

The repository located on shared directory Lintula can be accessed with the svn+ssh protocol through Lintula ssh-servers, for example kaarne.cs.tut.fi. For example :

linuxlaptop:~$ svn ls svn+ssh://tuser@kaarne.cs.tut.fi/share/XXXprojects/tproject/repository
tuser@kaarne.cs.tut.fi's password: Lintula password

linuxlaptop:~$ svn checkout svn+ssh://tuser@kaarne.cs.tut.fi/share/XXXprojects/tproject/repository
tuser@kaarne.cs.tut.fi's password: Lintula password

Subversion (TortoiseSVN) on TST windows workstation

Creating a repository for a project

A repository can be created on Lintula network disk with TortoiseSVN client on TST windows workstation, if network disk is available (the workstation is connected to TST network or VPN connection is active).

1.	Open file manager window in the folder you want to create the repository. This can be done for example by selecting Start -> Run and typing the name of the folder to the Open: textbox. In this example we use a project directory called tstadmin in the Department of Signal Processing project disk.
2.	Create a folder for the repository. Click right mouse button in the file manager and select New -> Folder. The name of the created folder will be the name of the repository.
3.	Create a repository in the folder created. Click the created folder with right mouse button and select TortoiseSVN -> Create repository here.
	The repository is created.

Checking out and accessing the repository with a TST windows workstation

A repository located on Lintula network disk can be accessed with TortoiseSVN client on TST windows workstation. If network disk is available (the workstation is connected to TST network or VPN connection is active), the repository can be accessed with file: URL and without network disk access, the repository can be accessed with svn+ssh URL via Lintula ssh servers. Using file: URL is easier, because you do not need to enter your Lintula password when updating the working copy or commiting to the repository.

1.	Create a folder for the working copy of the repository. You should use local disk, for example D:\user\username folder, for this, because no backups are needed. Open file manager for this folder and select New -> Folder.
2.	Select the folder created with right mouse button in the file manager and select SVN Checkout....
3.	In the Checkout window type the URL of the repository: If you use TST windows workstation, you can use file: URL, for example file:\\sgnsamba.cs.tut.fi\projects\tstadmin\svnrepo and if you are using some other computer (which can't use Lintula network disk), you have to use svn+ssh: URL, for example svn+ssh://tuser@kaarne.cs.tut.fi/share/sgnprojects/tstadmin/svnrepo where tuser is Lintula username.
