Migrating to Subversion
- Every sub-project of Jakarta gets a subdirectory in the Jakarta SVN repo.
- They use a tags/trunk/branches structure within said subdirectory, though they could further componentise and then use the tags/trunk/branches structure if it fits them better.
- The CVS repositories of "dead" projects are not targeted for immediate migration (e.g. jakarta-site).
Subversion provides many advantages over CVS, smoothing out its "excessive character" while providing the same approximate level of functionality, and a much better designed platform on which to develop tools. Sampling of improvements over CVS:
- move files within the repository and maintain the history
- delete directories (which are treated no different than any other versioned resource)
- treat groups of files in one commit as a single transaction (change set-like)
- significantly faster branching and tagging
Another major benefit is that administration of Subversion simplifies the life of the Infrastructure team. UNIX accounts need not be created for each user; user accounts are instead maintained in htaccess files, with authentication occuring over SSL.
- Is the community's toolset fully supported?
The tagging and branching model varies from that of CVS, and is only a "cheap" directory copy. Tags which are more than a simple directory tree get trickier. ie) tagging without tagging all the files, or tagging plus a set of files in a sibling directory. The trick of doing 'cvs status -v build.xml' to list known tags for a module is no longer available as well. Instead, the "tags/" directory in the repository may be browsed using a 'svn ls' or a web browser.
- Obliteration of files which should have never made their way into the VC repository (e.g. files with a non-ASF allowed license) can currently only be accomplished through a dump/edit/load of the entire repository by the Infrastructure team (resulting in a repository-wide maintenance window).
