VCI::VCS::Svn - The Subversion implementation of VCI
This is a "driver" for VCI for the Subversion version-control system. You can find out more about Subversion at http://subversion.tigris.org/.
For information on how to use VCI::VCS::Svn, see VCI.
For the repo argument to "connect" in VCI, pass the same URL that you'd pass to your SVN client, without the actual branch name. That is, pass a URL to the very root of your repository.
For example,
if I have a project called Foo that I store in svn.domain.com/svn/repo/Foo then the repo would be svn://svn.domain.com/svn/repo/.
Though Subversion itself doesn't allow relative paths in file:// URLs,
VCI::VCS::Svn does.
So file://path/to/repo will be interpreted as meaning that you want the repo in the directory path/to/repo.
In actuality, VCI::VCS::Svn converts that to an absolute path when creating the Repository object, so using relative paths will fail if you are in an environment where "abs_path" in Cwd fails.
VCI::VCS::Svn requires at least Subversion 1.1, and the SVN::Client perl modules that ship with Subversion must be installed.
These are limitations of VCI::VCS::Svn compared to the general API specified in the VCI::Abstract modules.
added,
removed,
modified and copied,
objects only implement Committable without actually being File or Directory objects.
This is due to a limitation in the current Subversion API.
(See http://subversion.tigris.org/issues/show_bug.cgi?id=1967.)copied files always show up in added,
they never show up in modified,
even if they were changed after they were copied.
This is because Subversion doesn't track that a copied file was modified after you copied it.
This is also consitent with how they show up in as_diff -- it looks like a whole new file was added.
copied,
added,
and removed instead of in moved.VCI::VCS::Svn performs well with both local and remote repositories,
even when there are large numbers of revisions in the repository.
We use the API directly in C (via SVN::Client),
so there is no overhead of actually using the svn binary.
Some optimizations are not implemented yet, though, so certain operations may be slow, such as searching commits by time. This should be easy to rectify in a future version, particularly as I get some idea from users about how they most commonly use VCI.
VCI::VCS::Svn is very new, and may have significant bugs. The code is alpha-quality at this point.
