Bug#677983: Differences after restarting acng

2012-06-28 Thread Eduard Bloch 

Hello Daniel, Steve, World,

* Daniel Hahler [Mon, Jun 25 2012, 03:43:48PM]:
 I am getting a similar error with apt-cacher-ng backported to Squeeze
 (via Ubuntu Lucid PPA) and think that it is related.

thanks for your support and the archives you sent in. Unfortunatelly,
I see no trace of a misbehaviour in the the fetcher code which I
originally expected. Now it looks more like issue with the hot cache of
download objects, especially because only a restart seems to fix it.

I will make a bigger code review as soon as possible but cannot provide
any hard ETA at the moment (personal reasons).

Btw, Daniel: the size of the Release files does not mean much. It's
always generated following the same format (same checksum and date
string length, same paths) and has the same size until the archive
config is changed.

Regards,
Eduard.

Bug#677983: Differences after restarting acng

I have noticed the following differences after restarting acng:

The Release file has the same size, but its contents differs:

I could imagine that acng had updated the GPG signature, but not the
Release
file itself and therefore causing this error.

The same might apply to the list of md5sums (which come from the
Packages file, too AFAIK).

Maybe acng does not update the Release file if it has the same size as
the one stored?
