Bug#354925: apt-cacher: cached files of same name but from different path_maps break apt-cacher
Package: apt-cacher Version: 1.5.1 Severity: normal *** Please type your report I am caching (amongst others) debian testing and ubuntu dapper repositories. When a package exists in both, and the package has exactly the same filename, the second repository that tries to use it does not download it (because it is already cached), but it mismatches the MD5 sum, and won't install. Suggest that there might be an option in the config file separate_repositories=1 If true, the cache name is appended to the packages path, and cached files from separate repositories don't interfere with each other. -- System Information: Debian Release: testing/unstable APT prefers testing APT policy: (500, 'testing'), (500, 'stable'), (70, 'unstable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.12-1-686 Locale: LANG=en_AU, LC_CTYPE=en_AU (charmap=ISO-8859-1) Versions of packages apt-cacher depends on: ii bzip2 1.0.3-2high-quality block-sorting file co ii libwww-perl 5.803-4WWW client/server library for Perl ii perl 5.8.8-2Larry Wall's Practical Extraction apt-cacher recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Now this is really bad. I have always assumed that Ubuntu people would modify the version string on every change. However, I had to learn now the many packages have been rebuilt without such changes. > Suggest that there might be an option in the config file > separate_repositories=1 Unfortunately, it is not that easy. That "path_map" thingie is a new feature and is not a core concept of apt-cacher (unlinke in apt-proxy). The packages have always been allowed to downloaded from anywhere (if not restricted by administrator by setting URL filters) and stored in the same directory so exactly this separation that you imagine has been actively avoided, all storage locations have been merged. Now I can change the code a bit to not remove the parent directories when storing the files. However the next problem are people that already have a working cache - the stored files would need to be moved to the "correct" locations but this is a bit complicated without knowing their origin. OTOH... a conversion script could do that since their metadata (checksums) is stored on some "Packages" file... the transition could be done transparent by hacking it into the cleanup script... I need to design the changes correctly (later) or it may break for someone. Eduard. -- Man muß den Mut haben, eine Verantwortung zu tragen. -- Walter Flex

This is only one of many reasons why mixing repositories from different distributions is not a good idea. You wouldn't mix Fedora and SuSE RPMs even though the packaging format is the same; it's equally problematic with Debian and Ubuntu. -- - mdz -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I *think* you're saying that you agree in principle that apt-cacher should separate the repositories :-) In case you're saying that I shouldn't be mixing debs from different distros installed on the one box, you're right, and I'm not. I'm running a mixed Debian and Ubuntu network, and would love apt-cacher goodness on both of these. Tony -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

I didn't realize apt-cacher could be used in this configuration, in which case, I agree that its assumption is invalid. -- - mdz -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
