====== RAD Lab SVN Repository ======

RAD Lab uses SVN along with SSH public keys to manage source code development and other documents that undergo revision.


===== Basics =====
Access to existing repositories are authenticated via SSH keys.

Currently, access to existing SVN repositories is provided by scm.millennium.berkeley.edu.
To access an existing repository:

<code>
$ svn command [options] svn+ssh://radsvn@scm.millennium.berkeley.edu/repo/<repo path>
</code>
We currently only support access via svn+ssh.



=====Granting Access=====
Access to the repositories is controlled via SSH keys installed in the <radsvn> account.

If you //have// access to scm.millennium.berkeley.edu, you can give yourself or someone else access to the SVN repository by following these steps:
  * Login as yourself into scm.millennium.berkeley.edu via ssh.    
  * Use the sudo command to edit ''~radsvn/.ssh/authorized_keys'' and add your or someone else's SSH **public** key to grant yourself or someone else access.
    * <code>sudo -u radsvn vi ~radsvn/.ssh/authorized_keys</code>
    * Note the format of already existing entries.  A shell script may be written to automate some of this soon
    * For local (EECS users, possibly ICSI as well), use their login for the argument to ''-tunnel-user=''.
    * For non-local (Intel, MS, nVidia, others), use something descriptive like "billgates@microsoft".
    * When I get creative, I may find a way to put all this under SVN as well
  * Now test to make sure that you can do the following command from your workstation/laptop/etc
          <code>$ svn list [options] svn+ssh://radsvn@scm.millennium.berkeley.edu/repo/<repo path></code>

If you //do not have// access to scm.millennium.berkeley.edu, ask someone in your research group who does to do this for you.  You can also mail your SSH **public** key to [[radlab-support@cs.berkeley.edu]] asking for SVN access.


Note: By default, svn will look in ~/.ssh/id_rsa or ~/.ssh/id_dsa for your private ssh key.  If you want to use a different key, you can use ssh-agent, but that is beyond the scope of this note.


=====Repository Organization=====
If you run <code>svn list svn+ssh://radsvn@scm.millennium.berkeley.edu/repo</code> you will see the following:

<code>
$ svn list svn+ssh://radsvn@scm.millennium.berkeley.edu/repo
courses/
docs/
papers/
projects/
users/
vendor/
</code>

This is a proposed hierarchy, <del>stolen</del> borrowed from <del>ICSI</del> ParLab, to help keep things organized.  Feel free to add to or modify it.

  * /courses - for courses taught related to RAD Lab
    * a separate directory for every class-semester combo
    * name in form <coursename>-<year>-<semester> cs399-2007-fall
  * /docs - Internal documents
  * /papers - research papers/technical reports for submission/publication
    * one directory for every paper
    * name in form <topic>-<conference>-<year>-<optional tag>
    * example: multicore-techrep-1998-finaldraft
  * /projects
    * local developed code (software, HW design layouts, etc)
    * a separate directory for each project
  * /templates
    * templates for various types of documents, scripts, etc
    * separate directory for each template, even if just a single file
  * /vendor
    * for code from 3rd parties that we might modify locally for our own usage
    * separate directories for the current version and other versions in parallel: ''foobar-cc-current'' and ''foobar-cc-2.2'' for example
