Currently our repository is setup on AFS, to access it we use ssh tunnel to yakut machines. Before running SVN commands make sure that you can connect from psdev to yakut with ssh – try to run ssh yakut. To avoid password prompts from svn commands you may need to run kinit on psdev to obtain AFS token. SVN repository is accessible to accounts in a special AFS group (g-lusi), if you are not a member of this group ask Andy or Igor to add you account to this group.

Using different release versions

User release directories involve a mix of packages from the user and system. scons will make sure the version associated with each is the same. Steps to upgrade a user release are below. When just using the system release - for example running psana from the home directory, you can easily switch the release version as follows:

To switch to "newest" release:

sit_setup newestana-current

To switch to a numbered release and use debug build:

sit_setup 1.2.3 dbg

Several environment variables that start with SIT_ will be changed by the above commands.

Switching to a different release or build options

For a user release directory, you may want to switch build options, or upgrade the release directory.
