clone: Create an identical instance of a repository (in a safe transaction) pull: Download revisions from a remote repository to a local repository; push: Upload revisions from a local repository to a remote repository; Local branches: Create a local branch that does not exist in the original remote repository
In Git, branches are very lightweight: a branch is only a reference to one commit. Distributed development Like Darcs, BitKeeper, Mercurial, Bazaar, and Monotone, Git gives each developer a local copy of the full development history, and changes are copied from one such repository to another. These changes are imported as added development ...
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]
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.
rcp can copy a file or directory from the local system to a remote system, from a remote system to the local system, or from one remote system to another. [16] The command line arguments of cp and rcp are similar, but in rcp remote files are prefixed with the name of the remote system:
The copied directory is linked to the original in the repository to preserve its history, and the copy takes very little extra space in the repository. All the versions in each branch maintain the history of the file up to the point of the copy, plus any changes made since. One can "merge" changes back into the trunk or between branches.
Many languages allow generic copying by one or either strategy, defining either one copy operation or separate shallow copy and deep copy operations. [1] Note that even shallower is to use a reference to the existing object A, in which case there is no new object, only a new reference. The terminology of shallow copy and deep copy dates to ...
improve compatibility with subsequent software versions. If the code of a function and the address of its entry point is changed, only the branch instruction in the branch table needs to be adjusted; application software compiled against the library, or for the operating system, does not need modification.
