RSE SVN

Revision as of 10:44, 29 August 2012

RSE projects are all developmental projects, with ongoing improvement and research.

For proper version management, backup and sharing, the projects are managed in a central SVN repository, hosted by the DTU Elektro production server Timmy.

Old CVS setup

SVN Access

To get access to the RSE SVN, you must have an account on the timmy server and be a RSE group member.

The SVN is accessed using the svn protocol, with the following connection string:

svn://[username]@repos.gbar.dtu.dk/jcan/mobotware

On a linux terminal an initial checkout of the (full) mobotware repository could be:

svn checkout svn://[username]@repos.gbar.dtu.dk/jcan/mobotware mobotware

and after that you just go to a place in the tree and update from the repository, or commit your changes by:

cd mobotware
svn update
make clean
make
<make changes>
svn commit -m "release remark - what is fixed/added"

The repository username/password is managed by jca@elektro.dtu.dk.

If you do not need to update the repository, then get the version available on campusnet, as described above.

Handling SVN projects

Managing the projects in SVN should be done according to the guidelines in the SVN book[1]. It is really good and usefull reading.

At a prevoius robot-meeting, there was given an introduction for SVN useage.

The slides from the presentation can be found here: Media:SVN_Best_practice.pdf

SSH Shared keys

A great toturial for generating shared SSH keys can be found in the article No More Passwords (with SSH) or password-less login

The method is in short (from your home directory):

ssh-keygen -t rsa
ssh-copy-id -i .ssh/id_rsa.pub [timmy_username]@timmy.elektro.dtu.dk

then (after a final password) you should be able to do a (in your svn tree)

svn update

and all the rest (including ssh-login to timmy) without being bugged with passwords.

SVN Keywords in source file

You may add SVN keywords anywhere in a source file and set SVN to update the keyword every time a new version is committed.

Add $Rev$, $Id$, $Author$ or $Date$ in the sourcefile, and tell SVN to update the used keywords

$ svn propset svn:keywords "Rev Id Author Date" poo.cpp poo.h
$ svn commit -m "Added keyword update"

Then the file is updated, to something like:

poo.h:

/**
* Mobotware sourcefile sample
* $Date: 2011-07-03 07:34:42 +0200 (Sun, 03 Jul 2011) $
* $Id: poo.h 1575 2011-07-03 05:34:42Z jca $
