Hi,

PEP 11 was recently deeply reworked to have "tiered platform support":
https://peps.python.org/pep-0011/

AIX is not supported by Python by this updated PEP. You can add a new
AIX buildbot worker, but results may be ignored if nobody pays
attention to it. See https://github.com/python/buildmaster-config/ to
add a new worker. You can look into old commits which add a new
worker.

On my side, I'm already maintaining (too) many buildbot workers, so I
simply cannot maintain more machines (analyze buildbot failures and
try fix them, at least report them).

Currently, there are already 2 AIX workers. Both are failing for at
least 4 months and nobody tried to fix them:

* https://buildbot.python.org/all/#/builders/438
* https://buildbot.python.org/all/#/builders/704

On PPC64 AIX XLC 3.x, Python even fails to build. It seems like the
disk is full:
---
xlc_r -c  -O    -qalias=noansi -qmaxmem=-1  -I./Include/internal  -I.
-I./Include    -DPy_BUILD_CORE -o Python/deepfreeze/deepfreeze.o
Python/deepfreeze/deepfreeze.c
1506-300 (U) Insufficient storage available.
/opt/IBM/xlc/13.1.3/bin/.orig/xlc_r: 1501-230 (S) Internal compiler
error; please contact your Service Representative. For more
information visit:
http://www.ibm.com/support/docview.wss?uid=swg21110810
make: *** [Makefile:2430: Python/deepfreeze/deepfreeze.o] Error 40
---

On PPC64 AIX 3.x, 5 tests failed:

 * test_cppext: "gcc: error trying to exec 'cc1plus': execvp: No such
file or directory" (missing C++ compiler?)
* test_eintr: test_flock() failed with PermissionError: [Errno 13]
Permission denied
* test_shutil: test_copyfile_nonexistent_dir() failed with
AssertionError("FileNotFoundError not raised by copyfile")
* test_tools: test_freeze_simple_script() failed with: [Errno 85] Too
many levels of symbolic links
* test_zipfile: test_create_directory_with_write() failed with:
AssertionError: 1103101968 != 5398069264

I'm not sure that today, it's worth to add a 3rd AIX machine if nobody
is available to fix issues on the two existing AIX machines.

By the way, a quick search in Python bug tracker give more more than
20 open issues specific to AIX. Oldest issues are open since 2010.
