X-Debbugs-Cc: debian-p...@lists.debian.org
Following #748380 (perl-policy: @INC changes for multiarch), we need
to add stricter dependencies on perl-base to the few non-binary module
packages currently using /usr/lib/perl5. Otherwise partial upgrades will
be problematic. While we can make perl-base Break the current versions
of such module packages with the old @INC, nothing prevents upgrading
the module packages before the perl core packages.
The affected packages are
libalien-wxwidgets-perl
libanyevent-perl
libcommon-sense-perl
libgtk2-perl-doc
libjcode-perl (arch:all oversight, see #749541)
libpar-packer-perl
Two of these (libcommon-sense-perl and libpar-packer-perl) already have
a binNMU'able dependency on the current perl upstream version. This is
almost enough, but doesn't cover the future possibility of changing
$Config{vendorarch} without a major Perl version bump. Extending the
perlapi-* requirement seems a more robust solution, as per the attached
patch.

Subject: [PATCH] All packages using Perl vendorarch directory need a perlapi-*
dependency
Having $Config{vendorarch} change between Perl major versions (for
multiarch or other reasons) implies that packages using it need a strict
dependency on those versions of perl-base that have a compatible search
path (@INC).
The vast majority of these packages are binary ("XS") modules, where we
already require a dependency on the virtual package perlapi-*, provided
by perl-base. The name of this virtual package will change when the
interface between the Perl interpreter and the modules changes.
If we consider @INC part of that interface, we can use the existing
mechanism also for the few nonbinary modules using $Config{vendorarch}.
This is a new requirement that currently affects six packages in
the archive.
