Hi! This is for post-bullseye, but I appreciate guidance if anyone has time. Shared library version transitions trigger uncertainty in me.
I want to upload a new upstream libidn release into Debian, but upstream has done a shared library transition. Bullseye will ship with libidn11-dev instead of libidn-dev too. Is the first step on the transition to provide a libidn-dev package experimental (and after the release, unstable) and make all reverse build-dependencies use it? If so, I plan to upload a new libidn version to experimental with this libidn-dev package, and then start to file bugs to all build reverse-dependencies to make them use libidn-dev. Once all bugs have been addressed, I can upload the new upstream version into unstable to finish the transition. Is that correct? The reverse build dependencies needs to be rebuilt against the new version though, and I'm not sure how that happens. I have prepared what I want to upload into experimental here: https://salsa.debian.org/debian/libidn/-/tree/experimental and I have attempted to re-build all reverse dependencies [1] here: https://salsa.debian.org/debian/libidn/-/pipelines/255418 The failed tests looks harmless: echoping is FTFBS and broken for other reasons, clickhouse just takes too long to build (but no indication of problem), and systemd appear to failed for some other reason. A 'git diff' between the version in bullseye and what I want to upload to experimental is shown below, together with debdiff-output between the built packages. Generally, does things looks okay? Specifically, what about the Breaks/Replaces/Conflicts? The d/changelog entry? Will the confusing 'Replaces: libidn11-dev' for the libidn11 (!) package in bullseye cause any problem? Am I right to drop it here? Should I wait post release with the upload to experimental, and/or filing the bugs? /Simon [1] thanks to https://salsa.debian.org/bzed/reverse-dependency-ci
