Google refers to delta updates as "smart updates." This has been implemented in Google's Android operating system devices that run on Android 2.3 or above. Google engineers have estimated that smart updates would be only about one third the size of a full update on average.
A patch is data that is intended to be used to modify an existing software resource such as a program or a file, often to fix bugs and security vulnerabilities. [1] [2] A patch may be created to improve functionality, usability, or performance.
Xdelta [3] is a command line tool for delta encoding, which stores or transmits the difference (deltas) between sequential data, instead of entire files.This is similar to diff and patch, except diff computes and shows the difference between two complete files, while patch is primarily designed for human-readable text files; Xdelta is designed for binary files and does not generate human ...
Unofficial patches are also sometimes called fan patches or community patches, and are typically intended to repair unresolved bugs and provide technical compatibility fixes, e.g. for newer operating systems, increased display resolutions [8] [9] or new display formats.
VCDIFF is a format and an algorithm for delta encoding, described in IETF's RFC 3284.The algorithm is based on Jon Bentley and Douglas McIlroy's paper "Data Compression Using Long Common Strings" [1] written in 1999.
DLL hell is an umbrella term for the complications that arise when one works with dynamic-link libraries (DLLs) used with older Microsoft Windows operating systems, [1] particularly legacy 16-bit editions, which all run in a single memory space.
Software development tools inspired by delta debugging include the bisect commands of revision control systems (e.g., git-bisect, svn-bisect, hg-bisect, etc.), which, instead of working on the program's code, apply the delta debugging methodology on the code history by comparing various versions until the faulty change is found.
AutoPatcher is an offline updater and alternative to Microsoft Update that can be used for installing software patches, service packs and other updates for certain Microsoft Windows systems.
