Panasync Tools provides a set of commands that enables version tracking among plain file copies. Retaining the basic functionality of standard copy commands, one can always track if a file has seen more updates than another file, and determine redundant or equivalent file copies. The approach is totally decentralized and serverless, and the functionality is achieved by small command-line user level programs that manipulate (by duplicating, comparing, joining and moving) any given file. By copying files with these commands users can detect if those files forgotten on disks or dispersed on different file systems and computers hold obsolete versions, and can thus be deleted, or need to be merged when depicting parallel updates. The updates, themselves can be done by any application since the system keeps a digest of the files to detect changes.
cvssh is a solution for securing a CVS pserver. The CVS pserver option is a useful but insecure tool for managing CVS repositories. Most approaches to securing CVS either involve ssh tunneling or avoidance of pserver altogether. The cvssh program offers a third alternative, which combines the simplicity of ext on the client with the flexibility of a pserver-based repository.
Vesta is an advanced system for source code control, versioning, configuration management, and building. It is an alternative to CVS+make. It has a variety of unique features including automatic language-independent dependency detection, guaranteed repeatability of builds, and seamless multi-site collaboration.
Code Librarian is a Web frontend to CVS repositories, conceptually a merge of Bonsai and ViewCVS/cvsweb. It allows browsing recent commits to the repositories monitored by date as well as browsing the repository by path as a tree of files and their revisions. Colored unidiffs are shown in popup layers one click away from any browse view, and the interface tries to be both clean and powerful, without scaring away the novice user.
p4delta works with a project that is in the Perforce configuration management system. It lists the local files that have been added, changed, or deleted. Content differences are summarized, i.e., the number of lines of code that have been added, changed, and deleted. It can also add, edit, and remove the appropriate files to/from Perforce.
The LibXDiff library implements basic and yet complete functionalities to create file differences/patches to both binary and text files. It uses memory files as file abstraction to achieve both performance and portability. For binary files, it implements both (with some modification) the algorithm described in "File System Support for Delta Compression" by Joshua P. MacDonald and the algorithm described in "Fingerprinting By Random Polynomials" by Michael O. Rabin. For text files, it follows directives described in "An O(ND) Difference Algorithm and Its Variations" by Eugene W. Myers. Memory files used by the library are basically a collection of buffers that store the file content.
