Say only between lensfun x.y.z to x.(y+1), or even for .z > releases? Currently, Lensfun is under heavy development. It is getting rid of old mistakes and heading towards version 1.0. Then, I expect things to settle down quickly. To answer your question, Lensfun does not have a policy for this (yet). So far, versioning has been without clear rules. But there is a proposal in the inbox of its maintainer to declare "z" as a clear patch release, so no ABI or DB changes. In contrast, a change in "y" may change both. > [...] > > Another solution could be double versioning the data, by library > SONAME and database version, > e.g. /usr/share/lensfun_$ABI/version_$DB/, which could allow to > have liblensfunN and liblensfunN-data, parallel-installable aside > each other SOVERSION. This would mean quite a bit of new developing and testing. If possible, I'd like to avoid it. Besides, there is a conceptual ugliness that the DB files do not depend on the ABI version; one would end up with duplicates. > (Btw, are you an upstream developer?

Yes, I am a developer, and everyone may contact me directly for Lensfun issues, or use the bug tracker, for that matter.

If there is only one ABI version of lensfun installed, this would work. If you want to make possible that liblensfunM can be installed locally parallely to liblensfunN, you need to put the database format version (not the ABI number) in the -data package. (Also note that the upcoming major Lensfun release will not be able to read older database versions. But this only makes the comparison expression a little bit longer.) > From what I see, changes in the data of a library (as long as > those data are accessed by the library and only by that) should > not matter to users of the library itself. This is correct. At least, if people read directly the library files, they are on their own.

Hallöchen! Lensfun just released a version 0.3.2. Changes in the build system are intended to make Debian packaging easy. Moreover, not only the library file is properly versioned (liblensfun.so.x), the same is now implemented for the database itself. Multiple database version can live happily together on the same filesystem. This is necessary because every binary library depends on a particular file format of the database, and this file format may change over time, independently of the ABI version. We suggest to count the database format version in the Debian package name as it is common for libraries: lensfun-data1, lensfun-data2, etc. Regards, Torsten Bronger. -- Torsten BrongerJabber ID: torsten.bron...@jabber.rwth-aachen.de ___ pkg-kde-extras mailing list pkg-kde-extras@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-kde-extras
