(sorry for my english) Yum-presto (formelly presto) is a plugin for yum (a pacman like for Fedora). This plugin optimize the size of the updates using deltarpms. The idea is check the difference between installed package and the new one to only download the difference, like a patch..

Using package deltas has been fully implemented in pacman but currently Arch does not use it. Allan

Sorry for my insistence... This implementation is in a new version of pacman? or Arch never will have this feature? -- Matias Hernández (Msdark) www.msdark.archlinux.cl ArchLinux-CL - WikiAdmin MSN: matiasfh@gmail.com Twitter : www.twitter.com/msdark Plurk : www.plurk.com/msdark Linux User: #445065 http://keys.gnupg.net/pks/lookup?op=get&search=0xEA3EEC672189419C

The current version of pacman supports this feature but the Arch repos are not set up to use it. Allan
Sorry for hijacking this a little. Is there documentation available on this? I'd like to exploit this feature with a personal repo (3 computers with slow connections use it); what should be done on the packaging/server side so that if the user enables UseDelta, it will work seamlessly with packages built with xdelta? That's as far as I understand this. There were discussions in the past but I never noticed how one would go about setting it up.

pkgdelta --help
Not a lot.... but this should get you started. pkgdelta (pacman) 3.3.0 Usage: pkgdelta [-q] <package1> <package2> pkgdelta will create a delta file between two packages This delta file can then be added to a database using repo-add. Example: pkgdelta pacman-3.0.0.pkg.tar.gz pacman-3.0.1.pkg.tar.gz
Awesome, thanks.

Awesome, thanks.
Testing is highly welcome, as well as feedback and suggestions, if we want this stuff to mature one day :)
