Package: libio-compress-zlib-perl
Version: 2.015-2
Severity: wishlist
Perl 5.10.1 RC2 bundles IO::Compress::Gzip 2.020 and other modules
from libio-compress-zlib-perl as part of IO-Compress.
This means that the separate libio-compress-zlib-perl package will become
uninstallable when perl 5.10.1 enters sid.
The uninstallability will also break versioned reverse dependencies:
libdebian-packages-compare-perl: Depends: libio-compress-zlib-perl (>= 2.011-1)
libemdebian-tools-perl: Depends: libio-compress-zlib-perl (>= 2.011-1)
liborlite-mirror-perl: Depends: libio-compress-zlib-perl (>= 2.011)
because versioned dependencies are not satisfied by provided packages.
It seems clear to me that this package has to be removed, possibly in
favour of libio-compress-perl if we want to keep that as a separate
package (see #538214).
So the packages listed above need to be changed.
All of these versioned dependencies will be satisfied by Perl 5.10.1
but not 5.10.0, so they should be something like
Depends: perl (>= 5.10.1) | libio-compress-zlib-perl (>= 2.011)
which allows for libio-compress-zlib-perl removal but keeps any Lenny
backporters happy.
I suppose the flag day for changing the dependencies can be avoided by using
Depends: libio-compress-zlib-perl (>= 2.011) | perl (>= 5.10.1)
instead, but I'm not sure if that's going to cause problems somewhere when
libio-compress-zlib-perl is removed. It's definitely not going to work
for Build-Depends, as the buildds (sbuild) ignore alternate dependencies
and only use the first one. (See #403246 for background about this.)
I'll clone and reassign the three bugs and mark them as blocking this
one. Setting the severity to 'wishlist' for now, but it's definitely
going to upgraded later.
