How about then bumping the API from 0 to 1?if you mean the SONAME, then you would require rebuilding all applications for no reason. There is absolutely no need for this.Then packages could depend unversioned on libjack1, instead of versioned on libjack0 >= 0.116.0.This would be terribly confusing, as it indicates that the SONAME has been bumped which is not the case.
I did not mean that Debian should bump SONAME, but would it not make sense for _upstream_ to do so when they claim their library ABI to now be stable?
That would make it possible to offer alternative jackd implementations:Alternative implementations simply should not provide a *-dev package, to enforce build-depending against the "main" jackd implementation (for now that means jakcd1, might change to a different one in the future).I suspect that is the simplest approach to multiple jack implementations in Debian.The issue with the various flavors of the *-dev package is the least problem here. Moreover, it is neither necessary nor sufficient. Quite the contrary, I think that we need to allow multiple *-dev packages, because some implementation might provide some extra, optional feature that is only declared in an implementation specific header.
Isn't that a contradiction to the upstream claim of library ABI being stable since version 0.116.0, or am I missing something?
