Git can be used in a variety of different ways, but some conventions are commonly adopted. The command to create a local repo, git init, creates a branch named master. [61] [111] Often it is used as the integration branch for merging changes into. [112] Since the default upstream remote is named origin, [113] the default remote branch is origin ...
git checkout --track creates a local branch from a remote branch, links them, and replaces the current working files with files from that branch. git fetch downloads changes from a remote repository into the local clone git reset makes the current branch point to some specific revision or branch. git reset --hard makes the current branch point ...
Local branches: Create a local branch that does not exist in the original remote repository; checkout: Create a local working copy from a (remote) repository; update: Update the files in a working copy with the latest version from a repository; lock: Lock files in a repository from being changed by other users
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
Child branches are branches that have a parent; a branch without a parent is referred to as the trunk or the mainline. [1] The trunk is also sometimes loosely referred to as HEAD, but properly head refers not to a branch, but to the most recent commit on a given branch, and both the trunk and each named branch has its own head.
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.
Version control systems attach metadata to changesets. Typical metadata includes a description provided by the programmer (a "commit message" in Git lingo), the name of the author, the date of the commit, etc. [9] Unique identifiers are an important part of the metadata which version control systems attach to changesets.
The contributor requests that the project maintainer pull the source code change, hence the name "pull request". The maintainer has to merge the pull request if the contribution should become part of the source base. [12] The developer creates a pull request to notify maintainers of a new change; a comment thread is associated with each pull ...
