Package: debian-policy Severity: wishlist Hereinafter "libraries" means "public shared libraries" per Policy §8 and only them.
I couldn't find in the Policy anything about underlinked libraries while I believe that having them is wrong and should be considered a bug. I mean libraries that are not directly linked against all libraries whose symbols are used. In the worst case this manifests as "undefined reference" lines in the ldd -r output and means that you must satisfy these references by linking additional libraries to the binaries that use the underlinked library (by linking against it or dlopening it). If you don't do this, sometimes you may not notice the problem until you invoke a specific code path that uses these references. Formally this also means that packages using the underlinked library may have RC bugs that can't be fixed, only worked around by linking additional libraries (cf. #694846 caused by #677721). In some cases a library doesn't have undefined symbols because of indirect dependencies but that's just a hidden bug and it can appear at any time when indirect deps change. In this case ldd won't show undefined references but automatic detection of the problem should still be possible. Also, if a library is underlinked we cannot use the dpkg dependencies to document the library dependencies. Also, underlinking of a library causes overlinking for binaries that use it and that is a problem by itself. See also http://wiki.mandriva.com/en/Underlinking So, I propose adding something like "Shared libraries should be linked against all libraries they use directly" to §8.1. -- System Information: Debian Release: 7.0 APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.7.0-wrar-1+ (SMP w/4 CPU cores; PREEMPT) Locale: LANG=ru_RU.UTF-8, LC_CTYPE=ru_RU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-policy-requ...@lists.debian.org with a subject of "unsubscribe".
