How to handle soname bump properly?

[Peter Lemenkov]

Hello All!

Consider, we got library libfoo and dependent utility bar.

If I updated library libfoo (successfully built with soname increased,
and ready to hit updates-testing via Bodhi), then how should I udate
bar?

If I rebuild bar, then against what version of libfoo it will be
rebuilt? Against old one or against new, which still not submitted to
updates-testing (to avoid unresolved dependencies).

After brief looking into fedora-wiki, I found nothing valuable
matching this topic.
