Package: debdelta
Version: 0.32
Severity: important

Hello,
thanks for fixing #544784 but the cache should be used better. For example

$ sudo debdelta-upgrade
...
48% (3939/s) bzr_1.16.1-1_1.18-1_amd64.debdelta

$ ls -1 /var/cache/apt/archives/bzr*
/var/cache/apt/archives/bzr_1.15-1_amd64.deb
/var/cache/apt/archives/bzr_1.16.1-1_amd64.deb
/var/cache/apt/archives/bzr_1.16-1_amd64.deb
/var/cache/apt/archives/bzr_1.17-1_amd64.deb
/var/cache/apt/archives/bzr_1.17~rc1-1_amd64.deb

$ apt-show-versions bzr
bzr/unstable upgradeable from 1.16.1-1 to 1.18-1

In the cache there is a more updated package than the one installed, so debdelta
should use that (but check if it's a complete package, not a partial download)
while downloading the delta.

Since I suppose deltas for more up-to-date packages are smaller than with older
one, and the aim of debdelta is to download less bytes, I've set the severity to
"important", but feel free to downgrade.

Regards,
Sandro
