Bug Description

Binary package hint: apt

apt-get/aptitude/synaptic etc should attempt to download the smallest files needed first. it would mean that things that are made up of small files could eventually be upgraded if (say) a dialup line disconnects before downloading linux-* and openoffice-* sized packages.

conceptually this would also allow installing minor parts of a system before the whole lot is downloaded (although i appreciate apt is a bit more complex then i make it sound ...)

It does sound like a good idea, but the reasoning behind the last statement is incorrect. The fact that the package is small doesn't imply that it is a dependancy rather than a dependant, plugins will be smaller the main package more often than not, but it actually is useless to download them if you cannot get the large dependancy.

Also i thought that apt-get resumes on partially downloaded files, or am i incorrect?

Currently apt waits until the last package in a group is downloaded before it begins installing the first one. If that was fixed, which is bug 313680, *then* downloading the smallest package first would allow the installation to start sooner. Until that is fixed, though, the order of download would make no difference.
