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 ...
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 ...
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 ...
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."
If any node fails the coordinator will timeout while waiting for the failed node. If this happens the coordinator sends an abort message to every node. The same action will be undertaken if any of the nodes return a failure message. Upon receiving success messages from each node in the voting phase the prepare to commit phase begins. During ...
The conflict is materialized if the requested conflicting operation is actually executed: in many cases a requested/issued conflicting operation by a transaction is delayed and even never executed, typically by a lock on the operation's object, held by another transaction, or when writing to a transaction's temporary private workspace and ...
