Just to clarify, there are 2 packages called libmusicbrainz4 - the old one, based on the upstream 2.1 source, is currently in Debian but broken http://packages.debian.org/source/sid/libmusicbrainz-2.1 - the new one, based on the upstream 4.0 source, is part of this RFS and is on the mentors site http://mentors.debian.net/package/libmusicbrainz Why the confusion? The old package is named after the ABI number in SONAME, the new one is named after the code version. Both Debian packages are called libmusicbrainz4, yet OLD: code v2.1.x, SONAME = libmusicbrainz.so.4, ABI = 4 NEW: code v4.0.x, SONAME = libmusicbrainz4.so.3, ABI = 3 Clearly, the new library has a distinct SONAME, so old packages won't link against it by mistake at runtime, so it is safe to have both libs on the same system concurrently, we just have to resolve the clash of package names. Packages depending on the old libmusicbrainz: ~$ apt-cache rdepends libmusicbrainz4c2a libmusicbrainz4c2a Reverse Depends: rhythmbox-plugins muine libtunepimp5 libmusicbrainz-ruby1.8 python-musicbrainz libmusicbrainz4-dev libkcddb4 kscd k3b gstreamer0.10-plugins-bad goobox gmerlin cynthiune.app Action items: - all those packages need a bug report filed against them to say that they depend on the obsolete SONAME. All such packages must release a fix into sid - the old libmb4 package should be removed from the archive of Debian by making a bug report as described here: http://wiki.debian.org/ftpmaster_Removals http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=671088 - as it is `API breakage' and not `ABI breakage', we should really try to have a distinct package name for the -dev package, although this is not necessary if the old package is removed from the Debian archive completely http://www.netfort.gr.jp/~dancer/column/libpkg-guide/libpkg-guide.html#sonameapiabi - according to the packaging guide and library best practices, we could potentially use the following convention: ABI number = 5 SONAME = libmusicbrainz.so.5 Package version = 4.0.x => Package name = libmusicbrainz5 and libmusicbrainz5-dev and filenames: libmusicbrainz5_4.0.0-1_amd64.deb libmusicbrainz5-dev_4.0.0-1_amd64.deb -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
