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.
Merge, users may freely edit files, but are informed of possible conflicts upon checking their changes into the repository, whereupon the version control system may merge changes on both sides, or let the user decide when conflicts arise. Distributed version control systems usually use a merge concurrency model.
Darcs 2.0 was released in April 2008 and introduced a more robust repository format, as well as a new patch semantic called "darcs-2", aimed at minimizing exponential merge conflicts. [5] The current development strategy focuses on implementing optimizations and adding new features, while maintaining the same repository format.
Version control (also known as revision control, source control, and source code management) is the software engineering practice of controlling, organizing, and tracking different versions in history of computer files; primarily source code text files, but generally any type of file.
Contributions to a source code repository that uses a distributed version control system are commonly made by means of a pull request, also known as a merge request. [11] The contributor requests that the project maintainer pull the source code change, hence the name "pull request".
An edit conflict is a computer problem that may occur when multiple editors edit the same file and cannot merge without losing part or all of their edit. The conflict occurs when an editor gets a copy of a shared document file, changes the copy and attempts to save the changes to the original file, which has been altered by another editor after ...
State-based CRDTs (also called convergent replicated data types, or CvRDTs) are defined by two types, a type for local states and a type for actions on the state, together with three functions: A function to produce an initial state, a merge function of states, and a function to apply an action to update a state. State-based CRDTs simply send ...
(This is a conflict between editors that is undetectable by the mechanism that decides whether to give the "edit conflict" message.) Some people edit by copying the source text into a text editor, making lots of changes (reorganising, adding new content, etc.), and then, when they're done, pasting the whole thing back onto Wikipedia as a single ...
