When a change is committed to a Subversion repository it is either fully completed or not done at all. So when people talk about Subversion's key features, they are usually talking about the things it does that CVS can't do.Ĭhanges to repositories are true atomic operations Don't worry, there's no radioactivity, that's atomic in the original Greek meaning, as in 'indivisible'. They designed Subversion to build on CVS's stengths, while avoiding its limitations. Subversion was originally written by a group of CVS (Concurrent Versioning System) users who were frustrated by CVS's drawbacks. With Subversion it's possible to manage multiple version of files at the same time. Subversion's ability to guard against damaging changes lets you try big risky changes, safe in the knowledge that should you cause a mess, it's easy to go back to the good old stable trunk.ĭevelopment need not take a linear path. When you work from a Subversion repository, you are always working with the latest version.Ĭhanges made through Subversion can be documented with messaging that help someone to understand why changes were made. If you make a mess when changing a file you can get back to the unspoilt version of the file with minimal time and effort. Although Subversion is most often used for software development it remains a mainstream version control system that is ready to handle files and documents of pretty much any type, and is occasionally put to novel use, such as managing backups, shared todo lists and even in the writing of collaborative fiction.Īll changes are recorded and available for retrieval. There's a specialist form of version control system (called a Configuration Management system) designed specifically for handling software development. Without version control systems, collaboration (especially in software development) quickly devolves into a horrible mess as different contributors make change to the same files, overwriting or just mangling each others work. Even when we work alone, most of us will make use of some form of version control, although often crude and inconsistent - such as when we use an application's SAVE AS and cook up a new file name to distinguish the new version from the old. Subversion is a version control system, a software toolset that helps people to manage changes that are made to collections of shared files. Beginner's Guide to Subversion 1.1 So, what's Subversion? Hold a locked file or even specify different protocols.Appendix 1. Lock files by specifying the hostname of a machine that is supposed to CIFS path = \(/vol/testvol/testvol/ ) host =10.
