Ok. Looking through the history, I think I found an equivalent change to model 
after: when support for FreeBSD 9 and older was removed.

I'm referring to 
https://www.python.org/dev/peps/pep-0011/#unsupporting-platforms.

"If a certain platform that currently has special code in CPython is deemed to 
be without
enough Python users or lacks proper support from the Python development team 
and/or
a buildbot, a note must be posted in this PEP that this platform is no longer 
actively supported."

https://www.python.org/dev/peps/pep-0011/#no-longer-supported-platforms

Should this list be updated to mention that AIX 5.3 and below are no longer 
supported?

Ok, so given that AIX is not officially supported, should PEP 11 be updated? The
change I made to drop dynload_aix may not be worth documenting there, but 
perhaps
dropping support AIX 5.3 and below (as stated in 
https://bugs.python.org/issue40680)
would be.

Interesting. Given that, shouldn't PEP 11 be updated with that change? Seems to 
me that PEP 11 only documents platforms with *official support*, so is AIX 
officially supported? The comment in the issue would indicate it is not 
officially supported, but it _is_ listed here: 
https://pythondev.readthedocs.io/platforms.html#python-platforms

[Python-Dev] PEP 11: Drop support for AIX releases without dlopen

2020-10-16 Thread Kevin Adler
Python has supported using dynload_shlib (using dlopen) on AIX since 
https://github.com/python/cpython/commit/c19c5a62aef7dce0e8147655b0d2f087965fae75
 in 2003. This is also about the time that AIX 4.3 went out of support, which 
is believed to be the AIX release that added support for dlopen. Considering it 
is now 20ish years later and in this time, every supported AIX release has had 
dlopen support, I suspect nobody has used or tested this code path in quite 
some time. I propose removing this support under PEP 11.

For reference, I opened https://bugs.python.org/issue42030 and changes were 
merged in https://github.com/python/cpython/pull/22717. I opened a PR to update 
PEP 11 in https://github.com/python/peps/issues/1653, but was told this needed 
discussion here. Sorry if this didn't quite follow the process correctly, I 
thought I had things in the right order, but I guess not. Also apologies if 
this is a duplicate, but my first message appears to have been lost/eaten 
(possibly a first-time moderation queue?).
