I'd also like to know what needs to be done to complete pkgviews.
The new infrastructure is something to replace mk/compiler, mk/wrapper, and mk/buildlink3. This new build system will get rid of most of the buildlink3.mk files in pkgsrc, and do more inspection of installed packages to determine what headers and libraries are available and what indirect dependencies should be pulled in. I'm hoping that this will considerably simplify pkgsrc infrastructure, and will be easier for developers to understand, maintain, and improve.
pkgviews is implemented almost entirely within the three modules I mentioned above, and I don't want to put pkgviews into the new bit yet, since it would complicate the code with something which I'm not entirely sure how many people are actually using. This is part of the reason why I just wanted to get a "show of hands" for who would be impacted if pkgsrc lost the ability to do pkgviews.
My understanding is that you still need to "reference count" directories (which can be manoeuvered around by adding a switch to pkg_delete to ignore the return results from an rmdir(2), and which I think would be a good addition anyway), and also the problems arising from the mini-packages debate, which I think are greatly reduced by the former change. Are there any more showstopeers?
I'll respond to this portion on tech-pkg.In any case, my intention when I started this thread was solely to determine how many users would be affected if pkgviews was removed from the system, and I'm still like to get a sense of those numbers.
