RSE SVN
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.
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+ssh protocol, with the following connection string:
svn+ssh://[timmy username]@timmy.elektro.dtu.dk/home/project-users/rse/svnrepo
As the SVN is run through SSH, you will be requested to input your SSH password MANY times, until you have setup your computer with a shared SSH key.
On a linux terminal an initial checkout of the (full) repository could be:
svn checkout svn+ssh://[timmy username]@timmy.elektro.dtu.dk/home/project-users/rse/svnrepo 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
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
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.
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: sf9dof.c 1575 2011-07-03 05:34:42Z jca $ */ #define REVISION "$Rev: 1575 $" ...
