Bug#180943: apt: when one source didn't update, re-update for modemed user?
Package: apt
Version: 0.5.4
Severity: wishlist
File: /usr/bin/apt-get
One thing you might address would be say one did a lengthy apt-get
update on ones modem, and one tiny file wasn't fetched.
Ok, if the user just does apt-get update again, many megabytes are
hauled wastefully over the line again and that one file won't
necessarily have any better luck at getting updated.
therefore, perhaps add http header last-modified etc. test... indeed
ah ha: use similar methods to avoid getting .debs already got, but
with Packages.gz files themselves instead of .debs...
e.g. below, this took many minutes. there is no easy way for the user
to retry without uselessly regetting unchanged files.
indeed, say a particular Packages.gz hasn't changed in a month, not
just since this connection. it too shoudn't be regotten.
