Please unblock package opencv
[ Reason ]
OpenCV specified dependencies between its library packages manually in
addition to ${shlibs:Depends}. According to the git history was
introduced ~10 years ago (no explanation in the commit) and was not
really kept up to date over the years. This resulted in circular
dependencies between the packages as reported in #979809.
[ Impact ]
Quoting from the bug:
| Circular dependencies involving shared libraries are known to cause problems
| during upgrade between stable releases, so we should try to avoid them.
Though I have not seen related problems on real systems.
[ Tests ]
I have compared the package dependencies before and after the patch. For
packages where the manually specified library match, ${shlibs:Depends}
defines them as (>= 4.5.1+dfsg), instead of the manually specified (=
4.5.1+dfsg-4), which I think is more correct.
For packages where additional library dependencies where specified, I
used readelf -d to make sure that those are actually not needed.
[ Risks ]
I think the risk is pretty low, ${shlibs:Depends} works well to the best
of my knowledge. On the other hand I can see that the consequences may
not be completely obvious. Given that the bugs are not release critical,
I'm fine with postponing this to bookworm as well. This is why I ask for
a pre-approval first. I could also upload to experimental and provide
some script to compare the packages if that helps.
[ Checklist ]
[X] all changes are documented in the d/changelog
[X] I reviewed all changes and I approve them
[X] attach debdiff against the package in testing
