Hi all, TL;DR;1 if your package depends on dbconfig-common please update your dependencies when my version 2.0.0 hits the archive (I expect in two weeks). TL;DR;2 should the new dbconfig-<dbtype> packages recommend or suggest the database server packages?
Since I took over the dbconfig-common package I have worked on the following feature in the dbconfig-common framework: binary packages to specify in the dependency chain which database types a package supports. The idea is the following. Each package that used the dbconfig-common framework to set up databases, should depend on dbconfig-<dbtype> | dbconfig-no-thanks instead of depending on dbconfig-common (as used to be the case and still works). What this solves is multiple issues: 0) Bug: 353617¹ 1) Because there is an alternative, dbconfig-<dbtype> can depend on the command-line client for dbtype, instead of <your package> recommending it. Thus properly signifying the hard requirement of dbconfig-common to have the command-line client available. 2) For multiple dbtype supported packages the system administrator now has a way outside of debconf to select which dbtype he wants by installing the right dbconfig-<dbtype> package. Currently the question will still be asked though. 3) The system administrator now has a way to say no-thanks to dbconfig-common (by installing the dbconfig-no-thanks package) on the system level, rather than per package via debconf. As a bonus, I can now add the database server packages to recommends, which should make life of the less experienced user easier. Do you think I should do this, or should I leave the database server package at the suggests level? Anyways, so what do you need to do? If your package depends on dbconfig-common (dd-list attached), the only thing you need to do² is revisit your dependencies/recommends/suggest. If you properly followed the dbconfig-common documentation, you have a dependency on dbconfig-common and at least a recommends (but probably a depends) on the command-line client(s) for the database type(s) you support. You should replace these with a depends on dbconfig-<dbtype> | dbconfig-no-thanks. Two examples. a) your package supports PostgreSQL, your dependencies now are Depends: dbconfig-pgsql | dbconfig-no-thanks b) your package supports sqlite3 or sqlite, your dependencies now are Depends: dbconfig-sqlite3 | dbconfig-sqlite | dbconfig-no-thanks For those of you that backport their packages via the Debian backports achive, I will provide a backport of dbconfig-common once version 2.0.0 reaches testing. Please speak up now if you think this is a ridiculous idea, if you have suggestions on improvements, if you have questions or otherwise. If people want to see how it all works for discussion, I am open to upload to experimental. And as always, please report bugs as you find them including wish bugs.
