Package: apt
Severity: normal

Hello,

while writting on new apt-cacher I faced a weird problem with apt.
It does reproducibly freeze somewhere after gettint a 404 from
non-existing index file.

The funny thing: when I enable Debug::Acquire::Http then it prints the
final GET request to STDERR but that request is never sent to the
server! See attached logs. Instead, it keeps looping around a select
with timeout somewhere.

Further, I would like to get more useful Debug information from rred or
from the synchronisation mechanisms inside of apt programs. I suspect
that it gets confused with something in apt-cacher's replys, but I
cannot see anything suspicious and all files (or corresponding 404s)
seem to have been delivered.

I cannot reproduce the problem on a second box, with apt version
0.6.43.3exp1.

Eduard.

Hello,

during a rewrite of some apt-cacher-ng internals I had a closer look at
apt internals. Well, I think the issue in topic cannot have been the
trouble maker, therefore I am closing this bug report.

Besides of that, some parts of apt's code are really crumbly. It
reproducibly fails to pass the message about lost connection from the
http client to the core WHEN the HTTP header has been transfered but the
data wasn't yet. Result is hanging around and telling the user wrong
explanation ("waiting for headers").

However, this deserves a separate bug report. Sorry for inconvinience.

Regards,
Eduard.
