[Python-Dev] 128 bit integer support
I have been doing some research on getting "int128_t" supported in Python,
and have hit a snag:
I've found that libffi does support this type, but sadly ctypes and cffi do
not. Adding to ctypes does not seem to be trivial, since the description of
an integer type is limited to a single character ("q" in the case of long
long). "q" is considered to be a length of 8, whereas what I really want is
the integer type "ll" which is correctly considered length of 16.
These musings are on OSX.
Can anyone give me some pointers as to why this has not been added to date,
and the best line of attack?
Regards, Fil.

Aren't you talking about the struct module? In ctypes, it seems it
would be sufficient to add a "c_int128" type (and/or "c_uint128").

Probably because noone needed it until now?
We have a comprehensive guide if you want to contribute a patch:
http://docs.python.org/devguide/
The first step would be to open an enhancement request on the
issue tracker, the discussion will then move on there:
http://bugs.python.org/
(if you want to enhance both the ctypes and struct modules, please open
a separate issue for each)
Regards
Antoine.

[Python-Dev] Python 3 is five years old
On 2008-12-03, Python 3.0.0 was released by Barry. I was actually on IRC the night when it happened, with Guido leaving his office across the hall from mine. We gave each other a high-five and then we both went home. Not exactly a party, but I know I at least breathed a sigh of relief that Python 3 was finally real. On this anniversary I just wanted to thank everyone who contributed to making Python 3 happen. Thanks to the core devs who worked hard to make Python better for everyone, even in the face of people yelling at us that we were crazy, killing Python, etc. Thanks to those in the community who stuck by the dev team and had faith we knew what we were doing and have continued to help everyone move forward and off of Python 2 to realize how much more pleasant Python 3 is to work with. At this point I'm willing to say I'm happy with how Python 3 has turned out and how the community has supported it. Python 3.3 was a great release and I think Python 3.4 will be as well. I see no reason to think that the language and community's forward momentum will not continue, leading to a day where Python 2 only exists for people stuck on RHEL. =) ___ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

Python 3.3 was a great release and I think Python 3.4 will be as well. I see no reason to think that the language and community's forward momentum will not continue, leading to a day where Python 2 only exists for people stuck on RHEL. =) Red Hat Software Collections (which includes a Red Hat supported Python 3.3 release) hit general availability in September, so even RHEL users have a fully supported migration option these days. It's still going to be a while before the RHEL system Python gets upgraded, but Fedora at least has a plan for that now :) Cheers, Nick. > > ___ > Python-Dev mailing list > [email protected] > https://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: https://mail.python.org/mailman/options/python-dev/ncoghlan%40gmail.com > ___ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

What about Linux/Unix/BSD with root account? If we have something similar, I may plan to write unit test for spwd module. --Vajrasky ___ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
