Okay, I think I got your point, reading this and some other mails in
this thread: you want to prevent ABI bumps to break plugins that are not
Yes, an ABI bump break every plugin that was compiled before it. If it
isn't affected, it has to be rebuild.
But I'm with Enrico here: I don't think ABI bumps will/should happen often.
And finally, if you want to protect from ABI breakage, you have to
protect every symbol, not only functions, but also structures and
structure members (even enums values may need this then).
So... while I'm not (and never was) against having a very flexible
dependency mechanism, I still think it's overkill, and won't it to make
everything complicated. If backbard compatibility is this important, I'd
prefer to simply keep the whole ABI stable, even if it may cost some
deprecated things and some "old and now useless stuff": it isn't really
nice either, but still seems less bloated to me.
But I'd be curious to see how you would implement this :)
