Repository and check-out

Currently, the MAS repository is on gamow, and only accessible from within physics.

There are separate repositories for core MAS (driver + libraries + command line applications) and user applications (squid tuning, file management scripts, idl scripts).

Core MAS repository is called "mas".

User MAS repository is called "mce_script". This has 3 parts:

Folder Purpose
script shell scripts, wrappers for mce_cmd and dsp_cmd
idl_pro idl scripts
src compilable code projects

The main branch is called "trunk". This means that to check out the main-line scripts folder, use the svn command

svn checkout --username <user> --password <pass> svn://gamow.phas.ubc.ca/mce_script/trunk/script <destination folder>

To checkout the entire mas source tree (trunk + branches)

svn checkout svn://localhost/mas


NOTE! To use SVN on foreign (non-UBC) machines, you must use ssh to port-forward (tunnel) the svn connections to gamow, which is protected. This is done like this:

ssh mhasse@phas.ubc.ca -N -L 3690:gamow.phas.ubc.ca:3690

You can replace "mhasse@phas.ubc.ca" with your username@any machine behind the physics firewall that you have access to. This command will ask for your password, and then remain open. As long as this command is running, you can do svn operations using the address "svn://localhost/..." and they will be redirected to gamow.


Branching and merging

Merging is accomplished by telling svn to apply a change history from one branch into the current location. For example, if we want branched from trunk/target at r100 and want to merge all changes in trunk/target up to the current head version into branches/expt/target, the merge command would be:

cd branches/expt/target
svn merge -r100:HEAD ../../../trunk/target
