binarydist

Package binarydist implements binary diff and patch as described on http://www.daemonology.net/bsdiff/. It reads and writes files compatible with the tools there.

This is forked from kr/binarydist, with some local modifications.

• This package uses mendsley's modified algorithm instead of original one. Not compatible with original bsdiff/bspatch.
• using index/suffixarray instead of qsufsort.
• This package uses CGO binding to libbz2 instead of calling "bzip2" binary externally. (increased performance on high workload)

Functions

func Diff

func Diff(old, new io.Reader, patch io.Writer) error

Diff computes the difference between old and new, according to the bsdiff algorithm, and writes the result to patch.

func DiffBytes

func DiffBytes(obuf, nbuf []byte, patch io.Writer) error

Diff With bytes

func Patch

func Patch(old io.Reader, new io.Writer, patch io.Reader) error

Patch applies patch to old, according to the bspatch algorithm, and writes the result to new.
