Created attachment 541850 [details] pygtk-2.24.0-r4.ebuild modified --disable-numpy Disable numeric python features
We can't just go and disable or make this optional blindly. --disable-numpy will make GdkPixbuf pixel_array stuff error out or not work. I am not willing to go and research if any of our pygtk consumers need this to work or not, as the goal for pygtk is to last rite it, not spend time improving the package.
The situation has changed a bit in the meantime - current numpy-0.17 is python3 only, therefore whoever has gimp installed gets downgraded to numpy-0.16 through this pygtk dependency. Is there a time frame when gimp is updated? For me the main other remaining package based upon pygtk is pybliographer - most other packages are simply unmaintained since 10 years and should probably be dropped. I have disabled numpy in pygtk and will report whether I experience problems.
This is also an issue now as numpy-1.17.4 is the only version with python3.8 support, hence, we cannot have python3.8 and this at the same time. I have seen that Fedora is having numpy-1.16.x for python2 while having 1.17 for python3... They also disabled numpy recently: https://src.fedoraproject.org/rpms/pygtk2/c/020c301a2029d7842ad26d03d744f8f5671a2db7?branch=master I would got for this last option if possible, at least we will have also Fedora users to help us to track if it breaks many things or not :/
sci is also maintaining numpy
Anyway, I see more packages needing numpy-python2 (lots of scientific programs that I use a lot too :S like VMD or pymol)... then, maybe the Fedora way of slotting numpy could work
This is their python2-numpy: https://src.fedoraproject.org/rpms/python2-numpy/blob/master/f/python2-numpy.spec
And the same in Arch: https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/python2-numpy
If you want I volunteer on helping with that python2 numpy slot, as, sadly, I will need it due to my job too as it has important reverse deps for us
Regarding pygtk, in Arch Linux numpy is optional since 2009 https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/pygtk&id=1699b45be1c900200c9b472177b0d7e00d6b71ac https://bugs.archlinux.org/task/14861 https://www.redhat.com/archives/fedora-devel-list/2009-August/msg00677.html https://bugzilla.gnome.org/show_bug.cgi?id=591745 -> per this, they explain that one alternative would be to RDEPEND on numpy from the packages still requiring them instead of pulling it from pygtk In any case, I can maybe open a separate report for the python2 numpy slot and keep this for pygtk as they could be handled independently :)
(In reply to Pacho Ramos from comment #9) > https://bugzilla.gnome.org/show_bug.cgi?id=591745 -> per this, they explain > that one alternative would be to RDEPEND on numpy from the packages still > requiring them instead of pulling it from pygtk No, it's not. pygtk numpy usage is compile-time optional, not runtime optional. Binary distributions could have it at compile-time and build against it, but then not declare numpy as a dep and make sure the consumers that need it do it instead; very hacky and bad, but a sort of solution that binary distributions could do. Not workable for us - we need it at compile-time anyways (just like binary distros then). The way forward here is checking if any pygtk consumers need these APIs (an important one like gimp doesn't seem to), and if yes - deal with it (last rite those, or change the code or whatever feels appropriate); ifor once that's a "no" - just unconditionally disabling numpy in pygtk. The long-term way forward of course is last riting pygtk, but that unfortunately isn't realistic anytime soon still.
That checking can be done mostly with a grep of the consumers source tree after identifying the method names to grep for based on HAVE_NUMPY or whatnot usages in pygtk sources.

Considering this as fixed then.
