I like to use Mercurial to track our local mods. http://www.selenic.com/mercurial/wiki/
There are some nice tools to support that: http://www.selenic.com/mercurial/wiki/index.cgi/WorkingWithSubversion I just do a simple setup though - keep a few copies of the code around. *. /dspace-pure/... - straight dspace-checkout *. /local-release/... - realease-ready code *. /work/... - work area When I have something in /work/ ready for release, then 'hg push' form work/ to local-release/ and run pre-release tests. When we're ready to pull in updates from dspace-repo, then svn update in dspace-pure/ hg pull the dspace-pure stuff into /work. Something like that. Long term dspace should consider moving to Mercurial for source control. Systems like Mercurial and Git (used by the Linux kernel team) make it easy to maintain local branches and repositories independent of the central "master" repository. I was disappointed to find that the dspace code base does not include a suite of JUnit regression tests - which complicates the update, merge process and forces add hock system-level testing. The current system's fragile design makes it difficult to add regression tests: *. use of classes instead of interfaces in the API makes it difficult to mock out subsystems *. extensive use of global (static) variables rather than dependency injection makes it difficult to isolate individual test cases. *. strong tie to database schema rather than object model with ORM mapping hidden away *. custom code rather than building on top of a J2EE platform (JBoss, Glassfish, Geronimo are all free) that provides database connection management, pluggable authentication, object-relational database mapping, logging, mail session management, transactions, etc. out of the box. I hope future versions of dspace include design changes, and introduce a suite of regression tests.
