Free version control system software for linux

Eclipsedarcs is a project to develop integration for the distributed version control system Darcs in the Eclipse IDE.

ViewMTN project provides a Web interface to the Monotone distributed version control system.

ViewMTN is a Web interface to the Monotone distributed version control system.

Features include listing all branches and tags, a graphical, clickable revision ancestry chart, diffs, and retrieval of the manifest of any revision as a tar file.

Automated Revision Control System is used to automatically monitor remote and local git, subversion, CVS, and even rsync repositories.
It notices changes and updates the local and remote repositories almost automatically. It requires either git, subversion, rsync, or CVS, and can be used for Web site maintainance, backup, communications, and many other purposes.
Enhancements:
- This release generally works a lot better to the extent that the authors are starting to using it for everyday file syncing and backup.

Distributed Concurrent Versioning System (DCVS) project extends the well-known version control system CVS and the file distribution and synchronization program CVSup with functionality to distribute CVS repositories with local lines of development and handle synchronization of the distributed repositories automatically in the background.
Development lines (branches) are owned by a repository server, repository servers efficiently update each other via CVSup, and CVS ensures correct server use on checkin and branch creation.
Enhancements:
- This release adds miscellaneous bugfixes and the security patches of CVS 1.12.13.
- There are now installation packages for Windows to be installed on Cygwin, for SUSE Linux 10, for FreeBSD 4, 5, and 6, and for Fedora Core 4.

Distributed Access Control System is a complete, light-weight, single sign-on and role-based access control system distributed under an open source license. It provides:
- extended authentication and role-based access control capabilities for Apache-based web services, CGI programs, and virtually any program or script;
- a wide array of flexible, modular, and efficient authentication methods, including two-factor authentication and hardware tokens;
- powerful, rule-based authorization checking that can be applied transparently to any resource or activity (such as web services, web content, and program features) by Apache-based web services and CGI programs, or virtually any program or script;
- an Apache 2.0/2.2 module, suite of CGI programs, and collection of command line tools for Unix-type platforms, such as Linux, FreeBSD, and Solaris.
Enhancements:
- This release includes an important bugfix to local_passwd_authenticate that prevents invalid passwords from being accepted.
- Some minor bugs have also been addressed, including some problems with dacs.quick(7).

Sin project is a framework that implements Continuous Integration on top of the Subversion version control system.
This can help to improve the overall productivity of your development team by reducing the number of build breakage experiences or even eliminating them entirely.
Main features:
Stable codebase
- Sin ensures that your codebase is stable at all times. Here, stable is defined as the codebase obeying all rules you set up in your Sin system (codebase must build, all tests must pass, etc.).
Sin saves your time
- Developers will never be bothered with the consequences of incorrect changes that cause broken builds. Sin automatically reverts (undoes) any change that violates one or more rules and notifies the developer who checked in the change, of the problem.
Sin is easy to set up and use
- Use the graphical setup application to set up your Sin system in minutes. Once set up, developers hardly know Sin is there until they check in a change that breaks the build - in which case Sin might just have saved the developer from public humiliation.
Easy reviewing
- Sin can send checked in changes in color-coded html by email for easy reviewing by other developers.
Use your existing build system
- No change to your existing build system is needed as long as your system can be built from the command line.
Sin is scalable
- Sin is a distributed system based on open standards like SOAP webservices and is easy to expand to handle new loads.

Transvn allows to maintain several or more separate patches to third-party source tree.
Transvn is primarily targeted at middle-scale and large-scale contributors to Open Source software projects.
Transvn allows:
- to easily maintain several (or many) non-trivial patches to third-party source tree
- to improve your communication with maintainer of that tree by making your changes more self-contained and reviewable
- to use all facilities of your version control system (currently only Subversion backend is implemented, but underlying idea could easily be ported to most modern version control systems)
Transvn is like Andrew Mortons patch-scripts, but explicitly bound to your version control system.
Enhancements:
- massive code refactoring
- transvn pull-start and transvn pull-next mostly implemented
- updated to work with Subversion up to 0.33
- clean up generated patches
