 +====== Subversion ======
 +
 +This tutorial is not about using a version control system, or about using Subversion, but about how to get started with Subversion on SDF. Other source control tools available for looking into are [[hosted git repos - gitea on sdf | SDF-hosted git]] (newer, distributed version control), [[CVS]] (older technology than SVN) and [[RCS]] (the granddaddy)
 +
 +
 +There are graphical tools such as TortoiseSVN, but we will start with Subversion's command-line tool (this is SDF we're talking about, right?) which is ''svn'', and //is installed on the cluster//
 +
 +Subversion is normally intended to be hosted on a server, so working with it locally with an SDF user account is a little awkward, requiring the use of ''file:<nowiki>//</nowiki>'' URLs. At the end of this tutorial, we will touch on how to set subversion up for remote access.
 +
 +===== Creating A Repository =====
 +
 +To create your own svn repository (place to store projects under source control) run the commands to setup a repository named "my-cool-project" in your homedir under ''$HOME/.svn_repos''. 
 +
 +
 +  $ mkdir .svn_repos
 +  $ svnadmin create .svn_repos/my-cool-project
 +
 +
 +You can then checkout your new repository into a working directory. 
 +
 +Make a directory for the working copies of your projects, say:
 +
 +  mkdir ~/coding-projects
 +
 +In this local setup where we are using ''<nowiki>file://</nowiki>'' URLS, Subversion requires that you use an absolute path to the repository. To learn the full path to your home directory type:
 +
 +   cd; pwd
 +
 +In the rest of this document you will need to replace '/path/to/homedir/' by the output of the previous command, or alternately, the ''$HOME'' parameter   
 +   
 +Then we can (locally) check out our project like so:
 +
 +  svn co file://localhost$HOME/.svn_repos/my-cool-project
 +
 +===== Importing A Directory =====
 +
 +If you want to add an existing folder to your repository:
 +
 +Let's import our website into our repository! :!: Note that after the import is finished, the original local directory //does not become a working copy//. To begin working on that data in a versioned fashion, you still need to create a fresh working copy of that tree.
 +
 +    cd html
 +    svn import -m "initial import" file://localhost$HOME/.svn_repos/my-cool-project/html
 +
 +
 +In this command
 +
 +  * 'import' is our 'svn' command
 +  * '-m "initial import"' is a message that will appear in the log.
 +  * '<nowiki>file://localhost$HOME/.svn_repos/my-cool-project/html</nowiki>' is the file pointer to our repo, with the last bit being the new directory where we want our 'html' stuff to go
 +
 +You can modify the message, the module name and the tags to your liking, just keep in mind that in the rest of this tutorial we will use 'html' for the module name.
 +
 +===== Checking It Out =====
 +
 +   cd ~/coding-projects
 +   svn co file://localhost$HOME/.svn_repos/my-cool-project/html
 +
 +To verify that you've checked out a working copy of just the //html// directory, first, do an ''ls html'' and see that the files are there. Second, run ''svn info''. It should output something like:
 +<code>
 +$ svn info html
 +Path: html
 +Working Copy Root Path: /sdf/arpa/ns/p/peteyboy/coding-projects/html
 +URL: file://localhost/sdf/arpa/ns/p/peteyboy/.svn_repos/my-cool-project/html
 +Relative URL: ^/html
 +Repository Root: file://localhost/sdf/arpa/ns/p/peteyboy/.svn_repos/my-cool-project
 +Repository UUID: 6909fbfb-0895-7146-9482-bf1fd1033119

 +
 +===== Accessing It Remotely =====
 +
 +One way to easily set up access to your svn repo for remote use is to set up [[trac_on_sdf|Trac]] on SDF
 +
 +Another is to run [[http://svnbook.red-bean.com/en/1.7/svn.serverconfig.svnserve.html#svn.serverconfig.svnserve.invoking | snvserve]], but this is complicated, as on SDF, subversion is installed on the cluster but not on the [[metaarray]], but users can only run processes on their [[meta_port_allocation| Allocated port]] on the metaarray. If a user wants to do this, they should post to [[bboard|bboard]] and request svn to be installed there.
