For reference, here's a few: Unicode::UCD -> Storable Module::Build -> Data::Dumper B::Lint -> Module::Pluggable Time::Piece -> Time::Local > Ideally the dependency would simply be expressed as a perl dependency > of the exact version on perl-modules (as is done for perl-base), and > this was originally how the package was set up. If such a setup was restored (see below), it would be possible to install perl-modules without perl. This could result in a broken Module::Build module on the system, for instance. Not sure if that's a real concern. There are currently only about 30 binary packages dependending on perl-modules but not perl, so those could certainly be changed easily if necessary. The few such source packages would be safe because perl is transitively build-essential via dpkg-dev (and probably others.) > This caused issues in unstable where the package became uninstallable > when a new version was available on one arch, but not built yet for > others and at the request of porters I changed the dependencies to be > looser allowing a newer version of perl-modules to be installed.

Now that we have Breaks in stable, couldn't this be solved with Package: perl-modules Version: 5.10.0-xx Breaks: perl (<< 5.10.0) ? > Additionally these dependencies must be modified if a file moves > between the packages, an example may be seen in the changelog for > 5.8.8-9 and in #377385: without the dependency changes it became > possible to have versions of perl and perl-base installed, neither of > which contained a module which had moved (similar issues occur when > moving modules to/from perl-base). This would be handled by upgrading the version in the Breaks field as needed. -- Niko Tyni nt...@debian.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
