Known limitations of the current implementation:
- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet
The leak is most visible by running:
./python -m test -R3:3 test_importlib
However, you can also see it by running:
./python -X showrefcount
Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.
I've left a couple of them in: zlib (third-party lib), getaddrinfo.c
(doesn't include Python.h, and probably obsolete), _sre.c (legitimate
use for the re.LOCALE flag), mpdecimal (needs to build without Python.h).

This introduces a new function, imp.extension_suffixes(), which is
currently undocumented. That is forthcoming once issue #14657 is
resolved and how to expose file suffixes is decided.
I can't test this on the snake farm (no aix box is working).
This change works for the submitter seems correct.
Can anybody test this on 32- and 64- bit AIX?
These built-in functions are replaced by their (now callable) type:
slice()
buffer()
and these types can also be called (but have no built-in named
function named after them)
classobj (type name used to be "class")
code
function
instance
instancemethod (type name used to be "instance method")
The module "new" has been replaced with a small backward compatibility
placeholder in Python.
A large portion of the patch simply removes the new module from
various platform-specific build recipes. The following binary Mac
project files still have references to it:
Mac/Build/PythonCore.mcp
Mac/Build/PythonStandSmall.mcp
Mac/Build/PythonStandalone.mcp
[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring. --Guido]
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
* in import.c, #ifdef out references to dynamic loading based on
HAVE_DYNAMIC_LOADING
* clean out the platform-specific crud from importdl.c.
[ maybe fold this function into import.c and drop the importdl.c file? Greg.]
* change GetDynLoadFunc's "funcname" parameter to "shortname". change
"name" to "fqname" for clarification.
* each GetDynLoadFunc now creates its own funcname value.
WARNING: as I mentioned previously, we may run into an issue with a
missing "_" on some platforms. Testing will show this pretty quickly,
however.
* move pathname munging into dynload_shlib.c
Here's a patch that avoids a warning caused by the "const char* pathname"
declaration for _PyImport_GetDynLoadFunc (in dynload_aix). The "aix_load"
function's 1st arg is prototyped as "char *pathname".
file per platform (really: per style of Dl API; e.g. all platforms
using dlopen() are grouped together in dynload_shlib.c.).
This is part of a set of patches by Greg Stein.
