Hi, I would like to upload liblzma5 to unstable, so liblzma in wheezy can match the upstream ABI. Relative to what's currently in sid, this involves a soname bump (2 → 5), introduction of versioned symbols, and some changes to the padding at the end of structs. liblzma never looks at this padding so even by simulating the worst case (liblzma2 and liblzma5 being indirect dependencies of a single binary through different paths, resulting in the two versions sharing a process image) I haven't been able to make it cause any trouble for partial upgrades. And I'm not aware of any packages that would trigger that worst case. You can find a liblzma5 package to test with at git://git.debian.org/collab-maint/xz.git experimental http://mentors.debian.org/debian/pool/main/x/xz-utils/xz-utils_5.1.1alpha+20110528-1~exp1.dsc The packaging takes the latest upstream version and reverts changes that introduced new ABI since the last stable upstream release. It is targetted at experimental and might be uploaded there soon. apt-cache points me to 14 binary reverse-dependencies counting each source package once[1], aside from xz-utils itself. From a transition coordination perspective, probably shogun, R, and KDE are the most notable ones. This is not urgent. I just would be happy to get it done so it doesn't have to happen later. Thoughts of all kinds welcome, of course.
