Package: apt-cacher
Version: 1.7.10
Severity: normal
Dear Maintainer,
Hello, after adding HTTPS sources ("deb https://deb.packager.io/gh/pkgr/gogs
wheezy pkgr")
on a client PC I noticed apt-cacher's CPU usage go through the roof.
Some poking around led to the discovery that ssl_proxy() doesn't appear to
notice EOF on the upstream connection, leading to an infinite loop. I added
a debugging message (and a sleep :P) inside the main loop, resulting in:

[ad infinitum]
Note that sysread() returns 0 on EOF, which is never checked for!
Steps to reproduce:
- configure apt-cacher to allow HTTPS, eg:
allowed_ssl_locations = deb.packager.io,
pkgr-production-deb.s3.amazonaws.com
- fetch something over HTTPS via apt-cacher, eg:
curl -x http://apt-cache:3142/ -D -
