[Python-Dev] Compiling 2.7.2 on OS/2

2012-01-05 Thread Paul Smedley


Hi All,

I'm working on updating my port of Python 2.6.5 to v2.7.2 for the OS/2 
platform.


I have python.exe and python27.dll compiling find, but when starting to 
build sharedmods I'm getting the following error:

running build_ext

Any suggestions?  A google showed a similar error on AIX with no
clear resolution.


Is it in the part that configures the "dbm" module?
This paragraph is already protected by a "if platform not in ['cygwin']:",
I suggest to exclude 'os2emx' as well.


It is - however adding os2 the the list of platforms to the ones to 
exclude gets me only a little further:


It then bombs with:

[The earlier call was with "__CONFIG_ARGS", for whatever difference that
makes.] It appears to be returning None instead of [] (or a populated
list).

In 3.2.2, at line 579 of sysconfig.py is
def get_config_var(name):
return get_config_vars().get(name)

That defaults to None if name is not a key in the dict returned by
get_config_vars(). My guess is that it always is and and the the value
is always a list for tested win/*nix/mac systems. So either setup.py has
the bug of assuming that there is always a list value for "CONFIG_ARGS"
or sysconfig.py has the bug of not setting it for os2, perhaps because
of a bug elsewhere.

At line 440 of sysconfig.py is
def get_config_var(*args):
global _CONFIG_VARS
if _CONFIG_VARS is None:
_CONFIG_VARS = {}

if os.name in ('nt', 'os2'):
_init_non_posix(_CONFIG_VARS)
if args:
vals = []
for name in args:
vals.append(_CONFIG_VARS.get(name))
return vals
else:
return _CONFIG_VARS

At 456 is
def _init_non_posix(vars):
"""Initialize the module as appropriate for NT"""
# set basic install directories
...

"CONFIG_ARGS" is not set explicitly for any system anywhere in the file,
so I do not know how the call ever works.
This looks pretty much the same as the code in 2.7.2 - I don't 
understand Python code well enough to debug the script :(


Thanks for the response,

Paul

[Python-Dev] What's required to keep OS/2 support in Python 3.3

2012-01-06 Thread Paul Smedley


Hi All,

I'm a little slow in responding to 
http://blog.python.org/2011/05/python-33-to-drop-support-for-os2.html, 
but I'm interested in stepping up to help maintain OS/2 support in 
Python 3.3 and above.


I've been building Python 2.x for a while, and currently have binaries 
of 2.6.5 available from http://os2ports.smedley.info


Unlike Andrew Mcintyre, I'm using libc for development 
(http://svn.netlabs.org/libc) rather than emx.  libc is still being 
developed whereas emx hasn't been updated in about 10 years.


I haven't attempted a build of 3.x yet, but will grab the latest 3.x 
release and see what it takes to get it building here.  I expect I'll 
hit the same problem with sysconfig.get_config_var("CONFIG_ARGS"): as 
with 2.7.2 but we'll wait and see.


Cheers,

Paul

I now have a dll and exe - however when it tried to build the modules, 
it dies with:

Could not find platform independent libraries 
Could not find platform dependent libraries 
Consider setting $PYTHONHOME to [:]
Fatal Python error: Py_Initialize: Unable to get the locale encoding
LookupError: no codec search functions registered: can't find encoding


Have done a small amount of debugging:
in get_codeset(), char* codeset = nl_langinfo(CODESET);
returns: ISO8859-1

Which can't be found by:
codec = _PyCodec_Lookup(encoding);

from
get_codec_name(const char *encoding)

Where is the list of valid codepages read from? Should ISO8859-1 be 
valid? I see some references to ISO-8859-1 in the code but not ISO8859-1


TIA,

Paul

I would look at this line:

LookupError: no codec search functions registered: can't find encoding

Normally the standard codec search function is registered when
importing the "encodings" module (see Lib/encodings/__init__.py), which
is done at the end of _PyCodecRegistry_Init() in Python/codecs.c.
There's this comment there:

 /* Ignore ImportErrors... this is done so that
distributions can disable the encodings package. Note
that other errors are not masked, e.g. SystemErrors
raised to inform the user of an error in the Python
configuration are still reported back to the user. */

For the purpose of debugging you could *not* ignore the error and
instead print it out or bail out.

Thanks - commenting out the ImportErrors block, I get:
ImportError: No module named encodings

So seems it's not finding modules - possibly related to the warnings about:
>> Could not find platform independent libraries
>> Could not find platform dependent libraries

Seems getenv() may not be working correctly...
