Right, user patches are rare, and patches that change the build system such that eautoreconf is necessary are even rarer. I'd say that EAPI 5 should provide an apply_patches_here function that can be called by ebuilds, but if the ebuild hasn't called the function, then it should fall back to applying user patches just after src_prepare.

No. Can you say why? There's no way for a program to work out what the ABI of something is (whatever that means), and there's even less of a way for it to know up-front. I believe what Peter might've been referring to would be some form of hashing of each and every library that is installed by a package. Just as a basic idea, one could probably (for instance) grab the LTVERSION of a libtool-built library, store that along with the emerge info, and link this same version when consumer ebuilds are built against it; then if the signatures changes the consumer ebuilds that were built against the (now incompatible) old signatures could be triggered for a rebuild. I'm not saying that this is a viable approach, simply describing a theoretical way it could be implemented. One of the advantages of going this way, though, is that it would probably be EAPI-independent as everything would be done internally by the PMS. The primary disadvantages I see is that 1-getting library signatures would be difficult, 2-many orders of magnitude of additional preprocessing would be necessary to build the deptree, 3-there wouldn't be any viable way for developer-based intervention when necessary. Finally, the above is just an example; I don't want to discuss merits of an approach like this or entertain possible implementations. Also, can we stop using the term ABI in reference to this please? It's misleading. Let's call them sub-slots instead. I think ABI fits well though? The situation is that A DEPENDs on B, and at some point B changes in a way that A must be rebuilt in order to run - right? The only reason that A wouldn't run anymore is that B's ABI changed? ABI has a fairly specific, technical meaning, which can be misleading in the general case. Is Python bytecode an ABI? Isn't Python bytecode an ABI, given that it's built or tied to a particular version (major.minor) of python??

This is a fairly important point: if the number of affected packages is small, there's no point in introducing sub-slots. I don't know about that -- I think we still very much need sub-slots. There is still a rather important distinction here -- SLOTS are currently used not to specify API, but to specify particular API groups that developers of said package are willing to support being installed (usually in parallel). For cases when developers decide it is not a good idea to support multiple APIs at a time (i go back to libpng here as an example of this current practice), 'SLOT=0' is still a valuable specification.

Well, not all people have infinite time to put that huge effort you sometimes would demand us to make things work perfectly :| There are two problems with that answer. Firstly, if getting something right takes a developer an extra ten minutes but saves each user one second of effort, it should be considered highly worthwhile. The fact that it isn't reflects very poorly upon Gentoo's attitude towards its users. Secondly, most of Gentoo's effort these days seems to be being spent cleaning up self-inflicted problems. Technical debt really is an issue here. By not doing things properly now, you're just adding to the problems facing future developers. (and looks like Exherbo developer also have the same problem as this model is still not implemented there, no? And that is normal, they also have time constraints for sure) Exherbo's generally pretty good at rewrite all the packages! type things. Partly that's because there are fewer packages (but then there are much better mechanisms for handling unpackaged packages), but it's also because QA and having a clean architecture are taken seriously there. Exherbo does have := and :*, and makes heavier use of slotting than Gentoo (partly due to having a much better 'alternatives' implementation). It doesn't have parts, because I've not had time to work out exactly how to get the resolver to do them cleanly. Once the package mangler side is done, experience has shown that there will be a very short delay before every relevant package is using it. -- Ciaran McCreesh signature.asc Description: PGP signature
