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.
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 ...
Meld is a visual diff and merge tool, targeted at developers. It allows users to compare two or three files or directories visually, color-coding the different lines. Meld can be used for comparing files, directories, and version controlled repositories.
(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 ...
Lock, changes are disallowed until the user requests and receives an exclusive lock on the file from the master repository. 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 ...
A CVS server stores the modules it manages in its repository. Programmers acquire copies of modules by checking out. The checked-out files serve as a working copy, sandbox or workspace. Changes to the working copy are reflected in the repository by committing them. To update is to acquire or merge the changes in the repository with the working ...
Instead, the developer is given an opportunity to either revert their changes or manually resolve the conflict. This prevents the entire project from entering a broken state due to a partially applied change set, where one file from a commit is successfully committed, but another file with dependent changes fails.
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".
