I just wanted to weigh in on this, as I don't think it is obvious how difficult doing this will be.
First, you simply cannot build-depend on them both. They conflict, and must conflict, because MariaDB has chosen to erroneously usurp the name libmysqlclient with their backward-but-not-forward compatible library. They simply cannot exist together. MariaDB's version contains symbols that MySQL's does not. I would argue that this makes it a different library. The appropriate thing to do is to rename it to libmariadbclient. This will allow programs which want to use its new functionality to actually make use of its new functionality. And if there is a need for building twice, it can be done with two builds, one using -lmariadbclient, and one using -lmysqlclient. Further, there is simply no reason to have a flexible dependency, but there are plenty of reasons for versioned dependencies based on symbols, which we get right now because of dh_shlibdeps. For basically no gain, trying to do a flexible dependency will complicate packagers' lives. Let people use libmysqlclient if they want, or libmariadbclient if they need. For this case, I'd say that mariadb can likely work fine with libdbd-mysql-perl as-is. If not, please explain why. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
