[Debian-astro-maintainers] Bug#1064308: libricohcamerasdk: identified for time_t transition but no ABI in shlibs

[Steve Langasek]

Source: libricohcamerasdk
Version: 1.1.0-4
Severity: serious
User: debian-arm at lists.debian.org
Usertags: time-t

Hi Thorsten,

Analysis of the archive for the 64-bit time_t transition[0][1] identifies
libricohcamerasdk as an affected package, on the basis that the ABI of the
library references the time_t type.

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

$ cat DEBIAN/shlibs
libmtpricoh 9 libricohcamerasdk (>= 1.1.0)
$

It is not obvious that we should rename the package to
'libricohcamerasdkt64' as part of this transition.

Looking at the archive, there is a package that depends on this library,
indi-pentax.

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 libricohcamerasdk without also
upgrading indi-pentax, or vice versa) will result in ABI skew and may result
in broken behavior.

Thanks,
