I can certainly understand how you could come to that conclusion, but like I said, that hasn't been even close to my experience, nor do I think it's representative of even a significant percentage of our users. > No matter how much some individuals > invest into FreeBSD ports, the overall loss of quality control is pretty > visible, and again - no single individual will fix that all.

I think it would be a mistake to believe that we don't have any quality control at all. I do think it's reasonable to ask whether what we have is adequate, and if not, how can it be improved. That's why I'm suggesting the stable ports tree idea as a step in that direction. > Even if they are volunteers, and everyone contributes on their own time > and resources, sure, but I would, personally, rather have 10000 (or > 1000, if there's no other choice) fully working ports again, instead of > those 22000 there all the time untested, broken, or missing features or > introducing regressions every minor update. Now you're talking! :) This is one of the reasons I have been so supportive of (and made some minor contributions to) the effort to deprecate stale ports. There is also a lot more work to be done in this area. That said, it's you and me against all of the (very!) vocal people who believe that we shouldn't ever deprecate anything. Go figure. :) >> Now, how do we fix this? It has been suggested numerous times that one >> solution to this problem would be a "stable" ports tree.

I'd like to think that we can do a little better than that. :) I also think that a non-trivial number of users will want to use the "latest and greatest" so I'm not quite as pessimistic about this as you are. > And / Or: > > 2.

This I think is a very valid concern, and one that will have to be addressed with vigor. That said, I think that there are a lot of users who would find value in a ports tree that is overwhelmingly stable, as opposed to always being the latest and greatest.

On the contrary, this is *exactly* the kind of thing that my idea would catch. More completely, my idea is something along the lines of: 1. Establish a baseline of what works with the existing ports tree via -exp run(s). 2. Branch the tree 3. New commits go to the head of the tree 4. "Periodically," we do an -exp run with the stable tree plus selected updates from head. If the tree is no worse off than the baseline promote the tested updates, update the baseline, lather, rinse, repeat. -- Nothin' ever doesn't change, but nothin' changes much. -- OK Go Breadth of IT experience, and depth of knowledge in the DNS.
