Package: cyrus-common
Version: 3.8.1-1
Severity: serious
User: debian-...@lists.debian.org
Usertags: time-t

Dear maintainers,

Analysis of the archive for the 64-bit time_t transition[0][1] identifies
cyrus-common as an affected package, on the basis that the headers could not
be compiled and analyzed out of the box using abi-compliance-checker[2], so
we have to assume it's affected.

However, cyrus-commons's shlibs file declares a dependency on a library
package name that contains no ABI information:

$ cat DEBIAN/shlibs
libcyrus 0 cyrus-common (>= 3.8.1)
libcyrus_imap 0 cyrus-common (>= 3.8.1)
libcyrus_min 0 cyrus-common (>= 3.8.1)
libcyrus_sieve 0 cyrus-common (>= 3.8.1)
$

It is therefore not obvious that we should rename the package to
'cyrus-common-t64' as part of this transition.

Looking at the archive, there are packages that depend on these libraries,
cyrus-admin and cyrus-clients.  Despite being built from the same source
package, they do not have a strict versioned dependency on cyrus-common but
instead use the shlibs.

Since there is no self-evident thing to do with the library package name
here, we will not be handling this package as part of the mass NMUs. 
Instead I am filing a serious bug because partial upgrades from bookworm to
trixie on 32-bit architectures (upgrading cyrus-common without also
upgrading cyrus-{admin,clients}) will result in ABI skew and may result in
broken behavior.

Thanks,
