Dear Debian people, I have completed a reasonably working version of 'debdelta', a package suite to compute differences between Debian packages. For sake of clarity, let's call '.debdelta' a file that encodes the differences between Debian packages, and '.deb' a Debian package. The command 'debdelta' creates a .debdelta ; the command 'debpatch' applies it to the old .deb to recreate the new .deb ; or, it can use the *installed* files of the old .deb. The command 'debdelta-upgrade' is meant to be run between 'apt-get update' and 'apt-get upgrade'; it downloads .debdelta files and recreate the new .deb files from them; always using the *installed* old version of the .deb, and not the old .deb file itself. Downloading .debdeltas instead of .deb packages can be a huge benefit for people with slow Internet access, and/or to keep traffic on servers low (as when the X security upgrade did saturate the server security.debian.org , see http://www.debian.org/News/2005/20050920 ) More info and details are in http://tonelli.sns.it/pub/mennucc1/debdelta/README The 'debdelta' package is in http://tonelli.sns.it/pub/mennucc1/debdelta/etch or http://tonelli.sns.it/pub/mennucc1/debdelta/sarge Unfortunately my repository of .debdelta is currently stored in a slow-bandwidth server; I would need some space (~800Mb) in some Debian server to host it (in a server where there is a copy of the archive). Any suggestions? The best would be if ftp-masters may help me set it up in ftp.debian.org . a. -- Andrea Mennucc
