Description Anton Bolshakov 2020-02-08 03:25:20 UTC
I'm compiling dev-qt/qtwebengine with "pax_kernel" use flag and facing this problem:

[11233/26168] /var/tmp/portage/dev-qt/qtwebengine-5.13.2/temp/python2.7/bin/python2 /usr/sbin/pypaxctl -sm ./mksnapshot
FAILED: obj/v8/mksnapshot 
/var/tmp/portage/dev-qt/qtwebengine-5.13.2/temp/python2.7/bin/python2 /usr/sbin/pypaxctl -sm ./mksnapshot
Traceback (most recent call last):
  File "/usr/sbin/pypaxctl", line 23, in <module>
    import pax
ImportError: No module named pax

That's because dev-python/pypax no longer supports python2

Comment 2 Arfrever Frehtes Taifersar Arahesis 2020-02-09 00:54:26 UTC
Real problem is actually in sys-apps/elfix.

sys-apps/elfix needs to use python-single-r1.eclass properly.

sys-apps/elfix installs:
 /usr/sbin/migrate-pax
 /usr/sbin/pypaxctl
 /usr/sbin/revdep-pax
These 3 files are Python scripts which import pax module.
Shebangs in these scripts need to be updated (using eclass functionality) from '#!/usr/bin/env python' to use Python interpreter selected using PYTHON_SINGLE_TARGET.

~dev-python/pypax-${PV}[ptpax=,xtpax=] dependency should be:
$(python_gen_cond_dep '~dev-python/pypax-${PV}[ptpax=,xtpax=,${PYTHON_MULTI_USEDEP}]')

Arfrever, what needs to change?  Should I just change the shebang to '#!/usr/bin/python' ?

Use python_fix_shebang function.

Changes are needed in sys-apps/elfix, not dev-python/pypax.

Are there anything I may help to solve this issue I also ran into? Thx: Dw.

OK, listen to this one, gentelmen!

A couple of days ago, python2 support has been removed from pypax:

dev-python/pypax: Remove py2
Signed-off-by: Michał Górny <mgorny@gentoo.org>
https://gitweb.gentoo.org/repo/gentoo.git/commit/dev-python/pypax?id=f700592b09cd09657f5ecaa2db0ffd0d23848772

The root of the problem in my opinion is, that qtwebengine and many other builds often still use python2, often their own compile-time internal instance (thunderbird, firefox for eg.).

No matter what shebang I sat the script misses the pax module and that's because it is looking for the python2 egg, IMHO.

After reintroducing 2_7 python compatibility to pypax, the compilation goes on flawlessly!

Additionally - to my disappointment - pax_kernel has been announced to be dead:

I have a zombie in my hands, so I have to maintain another personal ebuild, because it needs those markings. Blueness: I'm happy to share, if you are interested.

Comment 8 Arfrever Frehtes Taifersar Arahesis 2020-02-13 18:05:30 UTC
Since sys-apps/elfix does not use any Python eclass, it is unknown which Python versions it supports.
If sys-apps/elfix does not yet support Python 3, then, in addition to starting to use proper eclass, sys-apps/elfix needs to be ported to Python 3 quickly, or sys-apps/elfix will be removed from the tree.

looks like this hits migrate-pax on new tarballs as well

Taking a look at on the source code, it considers both Python 2 and 3.
