软件包摘要
Library that implements the rsync remote-delta algorithm
历史
项目历史与用法
librsync packages the rsync remote-delta idea as a reusable C library and the rdiff command-line tool. It is historically tied to efficient file transfer, backup, and binary-patch workflows rather than to the rsync network protocol itself.
项目历史
The project README credits Martin Pool and contributors from 1999 onward and says librsync was originally written for rproxy, an experiment in delta-compression for HTTP. The library exposes the core signature, delta, and patch operations so other programs can compute and apply network deltas without embedding the rsync protocol.
The modern GitHub release series shows 1.0.0 and 2.0.0 releases in 2015, with later 2.x releases continuing the library and rdiff tool as a small, reusable delta-compression component.
采用历史
The official README lists Dropbox, rdiff-backup, Duplicity, and others as users. That adoption pattern explains librsync's packaging footprint: backup and synchronization tools depend on the library behavior while presenting their own network, metadata, and policy layers.
使用方式
Library users generate a signature of an old file, compute a delta against a new file, and apply that delta with the old file to reproduce the new file. The rdiff executable exposes the same operations for shell pipelines and package-maintainer tests.
为什么软件包爱好者会关心
librsync is a good example of a package that is not the famous program named in the algorithm. It deliberately does not implement the rsync wire protocol, file metadata handling, SSH transport, or directory synchronization; it packages the transferable delta primitive that higher-level tools build around.
