[R-pkg-team] Bug#1063275: r-bioc-rhtslib: identified for time_t transition but no ABI in shlibs

[Steve Langasek]

Source: r-bioc-rhtslib
Version: 2.4.1+dfsg-1
Severity: serious
User: debian-arm at lists.debian.org
Usertags: time-t

Hi Andreas,

Analysis of the archive for the 64-bit time_t transition[0][1] identifies
r-bioc-rhtslib as an affected package, on the basis that it depends on some
library whose ABI is sensitive to time_t, which requires
reverse-dependencies to be built with LFS support enabled, and
r-bioc-rhtslib's own ABI is sensitive to LFS support.

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

$ cat DEBIAN/shlibs
libhts 3 r-bioc-rhtslib (>= 2.4.1+dfsg)
$

It is not obvious that we should rename the package to 'r-bioc-rhtslibt64'
as part of this transition.  Looking at the archive, there are packages
built from the separate r-bioc-rsamtools and r-bioc-variantannotation source
packages that depend on this library.

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 will result in ABI skew and may result in
broken behavior.

Thanks,
