Hi Science, The jupyter stack's upstream still support python 2, but it depends on ipython which has dropped it quite a while ago and has forced us to mask versions 6+ because circular dependencies make portage explode. It's IPython's main revdep. There's also matplotlib that dropped py2 in v3 and there's pressure to update the ebuild. Workarounds are clunky and even in best cases would cause users to have big "One or more updates/rebuilds have been skipped due to a dependency conflict" every time they update their world. Would you mind if we "artificially" dropped py2 on the whole jupyter stack (that is, drop python2_7 target even if upstream supports it)? It would fix the problem in a more graceful manner.
Soap gave me the green light on IRC, so I'll proceed shortly.
Python2 is supposed to die soonishly, so I am all for your action. But if there are protests, there is a way the wx guys went regarding gtk2-gtk3 using different revision numbers, r300 os gtk3 only: | a a a p r s | | | n | | l m r i p h m i s p f m f | e u s | r | p d a m a p c x p 6 s 3 a b i b | a s l | e | h 6 r 6 6 p 6 8 p 8 c 9 s r s p s | p e o | p | a 4 m 4 4 c 4 6 a k v 0 h c d s d | i d t | o --------------+-----------------------------------+--------------+------- 3.0.3 | + + + ~ + + + + + o o o ~ + o ~ ~ | 6 # 3.0 | gentoo --------------+-----------------------------------+--------------+------- 3.0.3-r300 | ~ + ~ o ~ + + + ~ o o o ~ + o ~ ~ | 6 o 3.0-gtk3 | gentoo --------------+-----------------------------------+--------------+------- [I]3.0.4 | + + + ~ + + + + + o o o ~ + o ~ ~ | 6 o 3.0 | gentoo 3.0.4-r1 | ~ ~ ~ ~ ~ ~ ~ ~ ~ o o o ~ ~ o ~ ~ | 6 # | gentoo --------------+-----------------------------------+--------------+------- 3.0.4-r300 | ~ + ~ o ~ + + + ~ o o o ~ + o ~ ~ | 6 o 3.0-gtk3 | gentoo 3.0.4-r301 | ~ ~ ~ o ~ ~ ~ ~ ~ o o o ~ ~ o ~ ~ | 6 o | gentoo ---
The wx team is mostly leio and he's working very hard to do things right. The python stack, however, is quite a bit larger than the wx one and I feel that this approach, if taken for all cases similar to ipython's, would be too much for the python team's to bear and we would end up with a situation similar to ipython and matplotlib: very long bump delay. I think we should choose a simple, straightforward approach to ensure that we actually go through with it without delaying too much because of the weight.
