Yeah. :-) Another point of view: Well, me, personally, I continue to do most of my research using Python 2 because I cannot afford to port everything to Python 3. And since I do only number crunching, meaning nothing with security implications, I am not particularly worried. [...] Once Python 2 lives in a largely isolated package sub-universe, I don't see much harm keeping it in Guix for now. If security issues become apparent, we might have to do something more drastic. And if you filter by =E2=80=99python2-=E2=80=99 from the dashboard, =20=20=20=20 many are broken but many are still fine. BTW, =E2=80=99python2-biopython=E2=80=99 is broken in the branch =E2=80=99purge-python2-packages=E2=80=99 and still there [1]. 1: > This effort is an attempt to reduce our dependencies on Python 2 as much > as possible, so that we can hopefully remove Python 2 from our tree > before 2030 comes ;-). I agree and I am advocating since 2019-10-31 [2] for an explicit plan. :-) However, my understanding of this plan after several discussions is: remove the python2- variants once they are broken. It appears to me surprising: we do not provide a schedule for the removals, then bang purge. 2: Well, as a hobbyist, I am fine with such purge. As a scientific practitioner using Guix at work, it is more annoying=E2=80=A6 >> bamm /gnu/store/17hs9c60isdk8sfkpi0280xzc0gkyxn1-bamm-1.7.3 [...] >> Therefore, I would not remove them; I have not checked which python2- >> dependencies they are using. > > If something is valuable up there, I'd suggest interested parties > contribute them to the Guix-Past channel. =E2=80=A6for instance, I use time to time the package =E2=80=99bamm=E2=80= =99. Because inferiors and time-machine, the removal of =E2=80=99bamm=E2=80=99 is not a big deal p= er se but I need some time to adapt some scripts, etc. Other said, I am fine with the purge and I volunteer to help in transferring from master to guix-past but we need a schedule, communicate on the purge and more importantly say when it will happen. :-) (maybe not a purge 2-3 days after an announcement on guix-devel following 2 weeks in a branch ;-)) Cheers, simon PS: Great script, BTW. :-)
