Working copies effectively function as remote backups, which avoids relying on one physical machine as a single point of failure. [5] Allows various development models to be used, such as using development branches or a Commander/Lieutenant model. [6] Permits centralized control of the "release version" of the project [citation needed]
Cherry-picking: move only some revisions from a branch to another one (instead of merging the branches) Bisect: binary search of source history for a change that introduced or fixed a regression; Incoming/outgoing: query the differences between the local repository and a remote one (the patches that would be fetched/sent on a pull/push)
Git supports rapid branching and merging, and includes specific tools for visualizing and navigating a non-linear development history. In Git, a core assumption is that a change will be merged more often than it is written, as it is passed around to various reviewers. In Git, branches are very lightweight: a branch is only a reference to one ...
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.
Users who can review the proposed changes can see a diff between the requested changes and approve them. In Git terminology, this action is called "committing" and one instance of it is a "commit." A history of all commits is kept and can be viewed at a later time. In addition, GitHub supports the following formats and features:
Copy-on-write can be implemented efficiently using the page table by marking certain pages of memory as read-only and keeping a count of the number of references to the page. When data is written to these pages, the operating-system kernel intercepts the write attempt and allocates a new physical page, initialized with the copy-on-write data ...
git add . The above command adds all of the files in the working directory to be staged for the git commit. After the commit has been applied, the last step is to push the commit to the given software repository, in the case below named origin, to the branch main: [3] git push origin main. Also, a shortcut to add all the unstaged files and make ...
Manual merging is also required when automatic merging runs into a change conflict; for instance, very few automatic merge tools can merge two changes to the same line of code (say, one that changes a function name, and another that adds a comment). In these cases, revision control systems resort to the user to specify the intended merge result.
