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.
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.
It can provide some protection against difficult merge conflicts when a user is making radical changes to many sections of a large file (or group of files). If the files are left exclusively locked for too long, other developers may be tempted to bypass the revision control software and change the files locally, forcing a difficult manual merge ...
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 ...
At the top of the edit-conflict page is an editing box containing Bob's version of the whole page, even if Alice is doing section editing. At the bottom of the edit-conflict page is a second editing box containing the text Alice was going to submit. This will be Alice's version of the page or section she was editing.
Shared file access is based on server-side pushing of folder information, and is normally used over an "always on" Internet socket. File synchronization allows the user to be offline from time to time and is normally based on an agent software that polls synchronized machines at reconnect, and sometimes repeatedly with a certain time interval ...
A relational database management system uses SQL MERGE (also called upsert) statements to INSERT new records or UPDATE or DELETE existing records depending on whether condition matches. It was officially introduced in the SQL:2003 standard, and expanded [citation needed] in the SQL:2008 standard.
In computer science, in the field of databases, read–write conflict, also known as unrepeatable reads, is a computational anomaly associated with interleaved execution of transactions. Specifically, a read–write conflict occurs when a "transaction requests to read an entity for which an unclosed transaction has already made a write request."
