Bug#518292: security.debian.org: Last-Modified times and lenny release

2009-03-05 Thread Mark Hindley 
Package: security.debian.org
Severity: normal


Hi,

I have just has a bug report for apt-cacher (#517874) which I have tracked down 
to
the Last-Modified times on s.d.o.

The file was

http://localhost:3142/security.debian.org/dists/stable/updates/contrib/binary-i386/Packages.bz2
 



which was originally cached from stable (etch, Last-Modified: Tue, 29
Jan 2008 16:55:18 GMT).  After lenny release this became oldstable, but
last modified time for this same index file in the new stable (lenny)
was Last-Modified: Sun, 08 Apr 2007 07:20:40 GMT so apt-cacher kept the
more recent (but wrong!) one.

I am not convinced there is a bug in apt-cacher here.

Obviously, if the OP had been using named paths rather than stable, all
would have been fine.

Is there anyway to ensure that Last-Modified times don't go backwards
when we upgrade distributions?

Thanks

Mark

This is in the domain of ftp-master, I'm reassigning this bug accordingly.


cheers,
