PSDM uses Subversion (SVN) for the code management and versioning task. Currently, official LCLS code such as PSANA, PYANA, etc. is located in the Software Repository which is enabled to LCLS software development team only. For those users who would like to develop their own code, contribute to the LCLS project, and share their code with other user groups, there is a users' software repository,

Creating Your Own User Repository

For most of these commands to work (except read-access to the readonly repo) you need a SLAC "kerberos ticket".  You can see your tickets with the command "klist". You can get a ticket with the "kinit" command like this:

kinit mySlacAccountName@SLAC.STANFORD.EDU  (the CAPS are required for SLAC.STANFORD.EDU!)

Create your local release directory and set environment:

cd <one-of-your-directories>

newrel ana-current <my-local-release-directory-name>
cd <my-local-release-directory-name>
sit_setup

Create package sub-directory with a few files:

newpkg <my-new-package-name>

Use the following command to create your own new package in SVN:

psvn -u newpkg <my-new-package-name>

...

 svn co https://pswww.slac.stanford.edu/svn/userrepo/<my-new-package-name>/trunk <my-new-package-name>

The above would work on machines around the world if you have a SLAC "kerberos ticket".  You can see your tickets with the command "klist". You can get at ticket on systems with a "kinit" command like this:

kinit mySlacAccountName@SLAC.STANFORD.EDU  (the CAPS are required for SLAC.STANFORD.EDU!)

If you don't have a kerberos ticket, you can get readonly access to the repository (anywhere in the world!) like this:

...

svn commit -m "my message describing changes"

psvn -u newpkg <my-new-package-name>
addpkg -u <my-new-package-name>
