Package: irssi Version: 0.8.17-1+b2 Severity: normal irssi 0.8.18 beta introduces an IRSSI_ABI_VERSION and will refuse to load load modules that are compiled against a different ABI version as returned by the module_name_abicheck() function.
This should prevent future ABI issues with irssi modules, but to properly solve #767103 and #772479 I think we should not depend on runtime checks and eventual bug reports by our users, but express the ABI in package relationships and do proper mini-transitions with binNMUs etc. I'm thinking of a mechanism similar to what Perl does for XS modules with perlapi-5.22.1 provided by perl-base. To this end, I suggest irssi Provides: a virtual package called something like irssiabi-$(IRSSI_ABI_VERSION), for which irssi-plugin-xmpp and irsi-plugin-otr can then add strict dependencies. The IRSSI_ABI_VERSION would have to be injected automatically at build-time. Suggestions where to find a lightweight implementation of such a mechanism for both provider and users very welcome!
