Re: A 'diff' eq for binaries?
Hi Ben,
The subject of patching .debs has come up again, and this time I have a
new solution to the problem. Xdelta 2.0-BETA has been released for about
a month now. See:
http://www.cs.berkeley.edu/~jmacd/xdelta.html
The new system is ideally suited to .deb distribution. The delta-compressed
storage management provided by Xdelta 2.0 automatically compresses multiple
versions of a file using deltas, but it also can extract a delta between
arbitrary versions. This allows a server process to generate exactly the
delta needed by a client on-the-fly, without storing all ("*EVERY*") delta
combinations.
I'm currently looking for developers interested in using this.
