Hi,hi, Freeplane depends on a number of libraries [1], and I guess the usual process for updating the package in case of an incompatible library upgrade, is to fix it upstream and include a patch until the package is updated to this upstream version. However, problems arise if there are packages for more than distro for upstream. e.g. Freeplane has packages for Debian and Mageia Linux and libjgoodies-forms-java has version 1.6 in Debian and version 1.4 in Mageia. Since it's difficult for my colleague to update the jgoodies-forms package in Mageia, I am currently maintaining my own patch for 1.6 indefinitely... libjgoodies-forms-java is probably a tough case [2]: deprecations are quickly removed and i.e. classes are renamed so that you can't support 1.4 and 1.6 in one codebase (unless you ship parts of jgoodies-forms in your package). (I was lucky with libcommons-io-java because Freeplane already uses 2.4) => is there a better approach to what I'm doing, i.e. fix upgrades quickly by adding patches and then arguing with my colleague about whether the patch can be applied upstream? => Under what conditions is the package renamed (i.e. "libjgoodies16-forms-java") if there are incompatible changes? Could you point me to the policy requirements? library should be renamed what there is an API breakage. In policy this refers to section 8.1 [0] for shared libraries. Though talk is more about C shared libraries, same kind of policy must be applied to Java libs, being also shared libraries. Perhaps in your case, a specific libjgoodies14-forms-java should be kept. Difficulty is to know that upstream API is broken if not specifically documented in changelog file. [0] http://www.debian.org/doc/debian-policy/ch-sharedlibs.html Olivier Shouldn't I get a warning (notification of all reverse dependencies) or a post on debian-java if an incompatible update will be uploaded? I guess that such incompatible updates are only common in the early development phase and not so much when move towards stable?
