[Android-tools-devel] Bug#1062209: android-libbacktrace (et al): identified for time_t transition but no ABI in shlibs

[Steve Langasek]

Package: android-libbase
Version: 1:34.0.4-1
Severity: serious
User: debian-arm at lists.debian.org
Usertags: time-t

Hi Roger,

Analysis of the archive for the 64-bit time_t transition[0][1] identifies
android-libbase (and other libraries from android-platform-tools) as a
package shipping a library whose ABI changes on 32-bit architectures with
64-bit time_t.

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

$ cat DEBIAN/shlibs
libbase 0 android-libbase (>= 34.0.4)
$

It is therefore not obvious that we should rename the package to
'android-libbaset64' as part of this transition, or to do similarly for the
other libraries built from this source.

Looking at the archive, there are packages built from both
android-platform-tools and from separate 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 (upgrading android-libbase without also
upgrading adb, fastboot, dexdump, etc) will result in ABI skew and may
result in broken behavior.

Thanks,
