Revision Control System
Revision Control System (RCS) is an early implementation of a version control system (VCS). It is a set of UNIX commands that allow multiple users to develop and maintain program code or documents. With RCS, users can make their own revisions of a document, commit changes, and merge them. RCS was originally developed for programs but is also useful for text documents or configuration files that are frequently revised. History Development RCS was first released in 1982 by Walter F. Tichy at Purdue University. It was an alternative tool to the then-popular Source Code Control System (SCCS) which was nearly the first version control software tool (developed in 1972 by early Unix developers). RCS is currently maintained by the GNU Project. An innovation in RCS is the adoption of ''reverse deltas''. Instead of storing every revision in a file like SCCS does with interleaved deltas, RCS stores a set of edit instructions to go back to an earlier version of the file. Tichy claims t ...

GNU Bazaar
GNU Bazaar (formerly Bazaar-NG, command line tool bzr) is a distributed and client–server revision control system sponsored by Canonical. Bazaar can be used by a single developer working on multiple branches of local content, or by teams collaborating across a network. Bazaar is written in the Python programming language, with packages for major Linux distributions, and Microsoft Windows. Bazaar is free software and part of the GNU Project. Features Bazaar commands are similar to those found in CVS or Subversion. A new project can be started and maintained without a remote repository server by invoking bzr init in a directory which a person wishes to version. In contrast to purely distributed version control systems which do not use a central server, Bazaar supports working with or without a central server. It is possible to use both methods at the same time with the same project. The websites Launchpad and SourceForge provide free hosting service for projects manage ...

Mercurial
Mercurial is a distributed revision control tool for software developers. It is supported on Microsoft Windows and Unix-like systems, such as FreeBSD, macOS, and Linux. Mercurial's major design goals include high performance and scalability, decentralization, fully distributed collaborative development, robust handling of both plain text and binary files, and advanced branching and merging capabilities, while remaining conceptually simple. It includes an integrated web-interface. Mercurial has also taken steps to ease the transition for users of other version control systems, particularly Subversion. Mercurial is primarily a command-line driven program, but graphical user interface extensions are available, e.g. TortoiseHg, and several IDEs offer support for version control with Mercurial. All of Mercurial's operations are invoked as arguments to its driver program hg (a reference to Hg – the chemical symbol of the element mercury). Olivia Mackall originated Mercurial and ser ...

Darcs
Darcs is a distributed version control system created by David Roundy. Key features include the ability to choose which changes to accept from other repositories, interaction with either other local (on-disk) repositories or remote repositories via SSH, HTTP, or email, and an unusually interactive interface. The developers also emphasize the use of advanced software tools for verifying correctness: the expressive type system of the functional programming language Haskell enforces some properties, and randomized testing via QuickCheck verifies many others. The name is a recursive acronym for Darcs Advanced Revision Control System. Model Darcs treats patches as first-class citizens. For the user, a repository can be seen as a set of patches, where each patch is not necessarily ordered with respect to other patches, i.e. the set of patches is only a partially ordered set. In many cases patches can be independently transmitted between various repositories. Many branching, merging, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotone (software)
Monotone is an Open-source software, open source software tool for distributed revision control. Monotone tracks revisions to files, groups sets of revisions into changesets, and tracks history across renames. The focus of the project is on integrity over performance. Monotone is designed for distributed operation, and makes heavy use of cryptographic primitives to track file revisions (via the SHA-1 Cryptographic hash function, secure hash) and to authenticate user actions (via RSA (algorithm), RSA Digital signature, cryptographic signatures). History Milestones Monotone version 0.26 introduced major changes to the internal database structures, including a new structure known by Monotone developers as a ''roster''. Monotone databases created with version 0.26 can not exchange revisions with older Monotone databases. Older databases must first be upgraded to the new format. The new netsync protocol is incompatible with earlier versions of Monotone. As Git inspiration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BitKeeper
BitKeeper is a software tool for distributed revision control of computer source code. Originally developed as proprietary software by BitMover Inc., a privately held company based in Los Gatos, California, it was released as open-source software under the Apache-2.0 license on 9 May 2016. BitKeeper is no longer being developed. History BitKeeper was originally developed by BitMover Inc., a privately held company from Los Gatos, California owned by Larry McVoy, who had previously designed TeamWare. BitKeeper and the Linux Kernel BitKeeper was first mentioned as a solution to some of the growing pains that Linux was having in September 1998. Early access betas were available in May 1999 and on May 4, 2000, the first public release of BitKeeper was made available. BitMover used to provide access to the system for certain open-source or free-software projects, one of which was the source code of the Linux kernel. The license for the "community" version of BitKeeper had allowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Changeset
In version control software, a changeset (also known as commit and revision) is a set of alterations packaged together, along with meta-information about the alterations. A changeset describes the exact differences between two successive versions in the version control system's repository of changes. Changesets are typically treated as an atomic unit, an indivisible set, by version control systems. This is one synchronization model. Terminology In the Git version control system a changeset is called a commit, not to be confused with the commit operation that is used to commit a changeset (or in Git's case technically a snapshot) to a repository. Other version control systems also use other names to refer to changesets, for example Darcs calls them "patches", while Pijul refers to them as "changes". Metadata Version control systems attach metadata to changesets. Typical metadata includes a description provided by the programmer (a "commit message" in Git lingo), th ...

Fork (software Development)
In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software. The term often implies not merely a development branch, but also a split in the developer community; as such, it is a form of schism. Grounds for forking are varying user preferences and stagnated or discontinued development of the original software. Free and open-source software is that which, by definition, may be forked from the original development team without prior permission, and without violating copyright law. However, licensed forks of proprietary software (''e.g.'' Unix) also happen. Etymology The word "fork" has been used to mean "to divide in branches, go separate ways" as early as the 14th century. In the software environment, the word evokes the fork system call, which causes a running process to split itself into two (almost) identical copies that (ty ...

Xdelta
xdelta is a command line program for delta encoding, which generates the difference between two files. This is similar to diff and patch, but it is targeted for binary files and does not generate human readable output. It was first released in 1997. The developer of xdelta is Joshua MacDonald, who currently maintains the program. The algorithm of xdelta1 was based on the algorithm of rsync, developed by Andrew Tridgell, though it uses a smaller block size. xdelta3 can generate standardized VCDIFF format, and it realized the compatibility among other delta encoding software which supports the VCDIFF format. It runs on Unix-like A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification.

Apache Subversion
Apache Subversion (often abbreviated SVN, after its command name ''svn'') is a software versioning and revision control system distributed as open source under the Apache License. Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly compatible successor to the widely used Concurrent Versions System (CVS). The open source community has used Subversion widely: for example, in projects such as Apache Software Foundation, Free Pascal, FreeBSD, SourceForge, and from 2006 to 2019, GCC. CodePlex was previously a common host for Subversion repositories. Subversion was created by CollabNet Inc. in 2000, and is now a top-level Apache project being built and used by a global community of contributors. History CollabNet founded the Subversion project in 2000 as an effort to write an open-source version-control system which operated much like CVS but which fixed the bugs and ...
