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 ...
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 ...
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)
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.
Changeset content should involve only one task or fix, and contain only code which works and does not knowingly break existing functionality. [ 13 ] Changeset descriptions should be short, recording why the modification was made, the modification's effect or purpose, and describing non-obvious aspects of how the change works.
It allows developers to work in independent branches and apply changes that can later be committed, audited and merged (or rejected) [9] by others. This model allows for better flexibility and permits for the creation and adaptation of custom source code branches ( forks ) whose purpose might differ from the original project.
Rebasing is the act of moving changesets to a different branch when using a revision control system or in some systems, by synchronizing a branch with the originating branch by merging all new changes in the latter to the former. For example, Git and Darcs do this (but Darcs extends the concept and calls it "patch commutation").
