What is the main purpose of traversing links to predecessors?
To identify the changes made in the previous version
What is the process of integrating changes from two versions?
Two-way integration
What is the process of integrating changes from three versions?
Three-way integration
What is the process of creating a new version by applying changes to the previous version?
Patching
What is the process of finding the differences between two versions?
Diffing
What is the process of combining changes from multiple versions into a single version?
Change integration
What is the purpose of DIFF in version control?
To determine the differences between two texts as a sequence of commands.
What is the purpose of PATCH in version control?
To apply differences generated by DIFF on other files.
What is the result of a two-way integration?
A new file is created from the two files, in which for each difference, a piece of text is selected interactively from either file.
What occurs when a piece of text is modified in both files in three-way integration?
A conflict occurs.
How does DIFF determine the shortest command sequence for two files?
Incrementally using the shortest command sequence for prefixes of the two files.
What is the primary function of three-way integration?
To consider a common original version and automatically take changes if a piece of text is only altered in one file.
What is the primary challenge in applying changes from different sources at the same time?
Ensuring compatibility of changes
In two-way integration, how does the user determine the contents of the integrated version?
Interactively, by selecting from the two new files
What happens in three-way integration when a piece of text has changed in only one file?
The changes are automatically applied
What is the edit distance between two strings, according to the DIFF algorithm?
The length of the shortest sequence of insert or delete commands
What is the purpose of the distance matrix in the DIFF algorithm?
To calculate the edit distance between two strings
What is the main advantage of three-way integration over two-way integration?
It considers the original version of the file
Learn about the challenges of integrating changes from different sources and the concept of two-way integration in version control systems. Understand how to determine the differences between file versions and make interactive decisions on what changes to keep.
