Hello,

see my post on the forum (http://bbs.archlinux.org/viewtopic.php?pid=238317#p238317)

Any chance that this "low-engineering" approach to implementing an xdelta solution could fly for arch, at least in the short term? This solution involves:

1. modified makepkg (see http://bbs.archlinux.org/viewtopic.php?pid=235654#p235654) 2. packagers having pkgver-1 in the makepkg build dir to create the delta 3. end-user implementing XferCommand with a custom xdelta aware script

If this works well for some users, a full c-code solution in pacman could be rolled out further down the track.

Thoughts? I see that archlinux.org and the mirrors have been experiencing some "bandwidth" issues after the python 2.5 release that perhaps underline the need for something like this in arch.

I agree; the XferCommand solution seems like an excellent way to prototype this and see if it is feasible. As Aaron and I have alluded to, we aren't real big on getting this done ourselves, but we will offer suggestions if asked. FYI: hopefully the mirroring of archlinux.org will vastly improve in the next week or so as we clamp down on the 600-some people rsync-ing from rsync.archlinux.org, of which maybe 50 are legitimate mirrors. -Dan
