This was clearly a duplicate ownership issue which spot dealt
with
correctly. perl-DBIx-Class already owns
%{perl_vendorlib}/DBIx/Class/
and thus there is no need for perl-DBIx-Class-EncodedColumn to
own the
directory since it requires perl-DBIx-Class (which owns the
directory).
Ian and Ralf are absolutely correct here. perl-* packages have for
years operated under the convention and explicit guideline that
anything we deliver under %{perl_vendorlib} or %{perl_vendorarch} must
be owned by the package providing it.
The canonical example here generally involves differing vendorarch/lib
dirs, as they're versioned by Perl. E.g. if perl-DBIx-Class was built
under 5.10.0, it's going to put its bits under
/usr/lib/perl5/vendor_perl/5.10.0. In the meantime if we go to Perl
5.10.1 and build perl-DBIx-Class-EncodedColumn under that level, it
will use /usr/lib/perl5/vendor_perl/5.10.1 as its directory... leaving
/usr/lib/perl5/vendor_perl/5.10.0/DBIx/Class/ unowned.
...or, if XS (arch-specific) bits were added to perl-DBIx-Class (which isn't
terribly unlikely), all of a sudden it would be using directories under
/usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread-multi, not
/usr/lib/perl5/vendor_perl/5.10.0... Also hosing directory ownership.
(noarch/arch changes like this are rare, but hardly uncommon.)
Another, perhaps clearer way of saying this is:
perl-DBIx-Class-EncodedColumn will require perl-DBIx-Class through the
virtual perl provide of perl(DBIx::Class); yet requiring perl(DBIx::Class)
does not guarantee that any particular directory under Perl lib paths (@INC)
will be created and owned.
Perl requires are managed through the perl(*) set of virtual provides.
Depending on a certain perl(*) provide to own specific directories is risky
at best, and a mess towards its worst. The only sane, clean and consistent
way to deal with this is for each perl-* package to own everything it
provides.
Other than "what a mess" :) ... yes this is fine and harmless from rpm
POV. It's the entirely silly cases like these (just a random sampling
from the big big list to make the point hopefully clear) I'd like to see
weeded out:
multiprovided dir /usr/share/man/man1
-> filesystem-2.4.21-1.fc11.x86_64
-> gnome-power-manager-2.26.1-3.fc11.x86_64
-> policycoreutils-2.0.62-12.6.fc11.x86_64
multiprovided dir /usr/share/man/man8
-> filesystem-2.4.21-1.fc11.x86_64
-> policycoreutils-2.0.62-12.6.fc11.x86_64
-> selinux-policy-3.6.12-39.fc11.noarch
multiprovided dir /usr/share/applications
-> filesystem-2.4.21-1.fc11.x86_64
-> system-config-httpd-5:1.4.4-4.fc11.noarch
-> xsane-0.996-7.fc11.x86_64
multiprovided dir /usr/share/locale/es/LC_MESSAGES
-> avahi-0.6.25-1.fc11.x86_64
-> filesystem-2.4.21-1.fc11.x86_64
-> glibc-common-2.10.1-2.x86_64
-> kde-i18n-Spanish-1:3.5.10-4.fc11.noarch
-> kde-l10n-Spanish-4.2.2-1.fc11.noarch
Practically all packages will end up having a relation to filesystem
anyway, so most likely no information lost if the cases like above are
simply ignored. But consider this:
multiprovided dir /usr/lib64/pkgconfig
-> freetype-devel-2.3.9-3.fc11.x86_64
-> libXScrnSaver-devel-1.1.3-2.fc11.x86_64
-> pkgconfig-1:0.23-8.fc11.x86_64
Quite clearly pkgconfig should be the only owner of that directory, and
this is a lost opportunity to automatically do the right thing in ordering
based on just the directory information.
