Public bug reported: Binary package hint: apt-proxy
This tool (the Karmic version) doesn't seem to get the caching of package information files right. When I run debootstrap over apt-proxy once, using ftp.de.debian.org as a backend, the directory /var/cache /apt-proxy/debian/dists/squeeze/main/binary-amd64 is used to cache Packages and Packages.bz2. However, on subsequent calls, a combination of strange behaviour occurs. I've tested it by simply calling wget 'http://localhost:9999/debian/dists/squeeze/main/binary-amd64/Packages.bz2'. * First of all, apt-proxy doesn't take the file from the cache, but instead tries to download it again. * Second, it tries to download it twice, as can be confirmed with some ngrep logging: #### T 192.168.0.8:55051 -> 141.76.2.4:80 [AP] GET /debian/dists/squeeze/main/binary-amd64/Packages.bz2 HTTP/1.0..host: ftp.de.debian.org.... ### T 192.168.0.8:55052 -> 141.76.2.4:80 [AP] GET /debian/dists/squeeze/main/binary-amd64/Packages.bz2 HTTP/1.0..host: ftp.de.debian.org.... * Third, one of the two streams seems to terminate, which might be a server-side policy. The manifestation of this issue on the user side looks as follows: --2010-03-07 09:43:34-- http://localhost:9999/debian/dists/squeeze/main/binary-amd64/Packages.bz2 Resolving localhost... 127.0.0.1, ::1 Connecting to localhost|127.0.0.1|:9999... connected.
