[gentoo-dev] News item: Python ABIFLAGS rebuild needed

[Mike Gilbert]

Hi,

Please review the news item below. I would like to send this out early next
week.


Title: Python ABIFLAGS rebuild needed
Author: Mike Gilbert <floppym@gentoo.org>
Content-Type: text/plain
Posted: 2015-12-11
Revision: 1
News-Item-Format: 1.0
Display-If-Installed: >=dev-lang/python-3.3.5-r4:3.3
Display-If-Installed: >=dev-lang/python-3.4.3-r4:3.4
Display-If-Installed: >=dev-lang/python-3.5.0-r3:3.5

For several years, Gentoo has been patching python3 in a way that is
incompatible with PEP 3149 [1]. Gentoo has been enabling the PyMalloc feature,
but our python packages have not carried the appropriate ABI flag.

We have removed this patch from the most recent dev-lang/python ebuilds at
the time of this writing. One result of this is that any packages which
install python extension modules must be rebuilt.

You should rebuild affected packages using the following command.

emerge -1v $(find /usr/lib*/python3* -name '*cpython-3[3-5].so')

You may experience build failures in related packages until this has been
completed.

Syntax of these headers is limited to EAPI 0, therefore you cannot use
slot dependencies there.

That sucks.

How do we change that?

Any suggestions for how I can adjust my news item in the short term?

It is worth noting that GLEP 42 makes no mention of EAPI, and current
versions of portage do support slots in dependency atoms used in news
items.

I guess it's a matter of documenting this somewhere. Where would that be?

We should update GLEP 42 and introduce a News-Item-Format 1.1 that
supports EAPI 5 for dependency syntax.

(This has come up several times in the past already, but for some
reason nobody is willing to take the initiative for updating the GLEP.
Everyone seems to be happy with a workaround for their own news item.)

Thank you. After skimming thought GLEP 1 to refresh my memory, I have
filed bug 568068 to propose the change.

The council has been approved NEWS item format 1.1 supporting EAPI=5
style package dependency specification.
