Subversion
From Knowledge Base
Introduction
Subversion is an open source version control system developed by Tigris and volunteers.
A Subversion repository is a centralized store containing all the files and directories relating to a project. When changes are made to the project they can be "committed" to the repository. The repository is an historical record of all the project, containing not only the current revision but also all previous revisions.
The benefits of using a version control system like Subversion include:
- Serves as an off-site backup for valuable project files
- Allows multiple people to work on a project at the same time and share their changes
- Allows even a single developer working alone to work on a project using several different machines and keep all the versions synchronized
- Provides a convenient way of rolling back undesired changes
- Encourages a disciplined working methodology in which a developer works on discrete problems and solves them one by one
- Provides a convenient way of visualizing and inspecting changes in an evolving code base
- Provides a convenient way of accepting modifications to a code base ("diffs") from third parties
- Provides a powerful mechanism for branching a code base and maintaining branches
- Provides a convenient way of tagging a code base in a certain state (like taking a "snapshot") and going back to that state at any time in the future
- Intrinsically maintains of logs of changes to a project (due to the presence of "commit" messages for each change)
Subversion and Wincent products
Up until July 2007, all of the code for all Wincent products was managed via Subversion (with an additional SVK layer used for development purposes). In July 2007 I started migrating to Git.
The source code for Wincent's open source products was available to the public via Subversion access to a public repository hosted at svn.wincent.com. The closed source products were also stored in a Subversion repository.
At the time of writing (December 2007) the Subversion repositories are still online but no new commits have been made to them for many months; all continuing development work takes place using Git.
Products for which public Subversion repositories exist include:
See http://git.wincent.com/ for a web-based interface to the new Git-hosted public repositories.
