In version control, merging (also called integration) is a fundamental operation that reconciles changes made to a version-controlled collection of files. Most often, it is necessary when a file is modified on two independent branches and subsequently merged. The result is a single collection of files that contains both sets of changes.
Merge tracking: describes whether a system remembers what changes have been merged between which branches and only merges the changes that are missing when merging one branch into another. End of line conversions : describes whether a system can adapt the end of line characters for text files such that they match the end of line style for the ...
Git implements several merging strategies; a non-default strategy can be selected at merge time: [56] resolve: the traditional three-way merge algorithm. recursive: This is the default when pulling or merging one branch, and is a variant of the three-way merge algorithm.
The users of the version control system can branch any branch. Branches are also known as trees, streams or codelines. The originating branch is sometimes called the parent branch, the upstream branch (or simply upstream, especially if the branches are maintained by different organizations or individuals), or the backing stream.
PVCS Version Manager (originally named Polytron Version Control System) is a software package by Serena Software Inc., for version control of source code files.. PVCS follows the "locking" approach to concurrency control; it has no merge operator built-in (but does, nonetheless, have a separate merge command).
[1] [2] [3] Git, the world's most popular version control system, [4] is a distributed version control system. In 2010, software development author Joel Spolsky described distributed version control systems as "possibly the biggest advance in software development technology in the [past] ten years".
Source Code Control System (SCCS) [open, shared] – part of UNIX; based on interleaved deltas, can construct versions as arbitrary sets of revisions; extracting an arbitrary version takes essentially the same time and is thus more useful in environments that rely heavily on branching and merging with multiple "current" and identical versions
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.
