by Paul Ganssle March 29, 2020

March 29, 2020

Greetings! Last year at the Language Summit, I proposed to add additional concrete time zones to the standard library <https://pyfound.blogspot.com/2019/05/paul-ganssle-time-zones-in-standard.ht…> . After much work and much more procrastination, I now have now put together my first proposal: support for the IANA time zone database <https://www.iana.org/time-zones> (also called tz, zoneinfo or the Olson database; Wikipedia <https://en.wikipedia.org/wiki/Tz_database> ).

Enum._convert should change __repr__ and/or __str__ to use module name instead of class name
by Ethan Furman March 28, 2020

March 28, 2020

Serhiy had the idea of having Enum._convert also modify the __str__ and __repr__ of newly created enumerations to display the module name instead of the enumeration name (https://bugs.python.org/msg325007): --> socket.AF_UNIX <AddressFamily.AF_UNIX: 1> ==> <socket.AF_UNIX: 1> --> print(socket.AF_UNIX) AddressFamily.AF_UNIX ==> socket.AF_UNIX Thoughts? -- ~Ethan~

March 27, 2020

As (first-time) BDFL delegate, I accept PEP 573 for Python 3.9, "Module State Access from C Extension Methods" https://www.python.org/dev/peps/pep-0573/ Petr, Nick, Eric and Marcel, thank you for your work and intensive discussions on this PEP, and also to everyone else who got involved on mailing lists, sprints and conferences. It was a long process with several iterations, much thinking, rethinking and cutting down along the way, Python 3.7 *and* 3.8 being missed, but 3.9 now finally being … [View More]

MacOS pkg bundles openssl, but doesn't include a cert bundle?
by Matt Billenstein March 23, 2020

March 23, 2020

Hi, installing the latest 2.7.16 MacOS installer, functions in urllib will attempt to load trusted certs from: /Library/Frameworks/Python.framework/Versions/2.7/etc/openssl/cert.pem But this file is not shipped with the installer package - this makes urlretrieve and friends fail on https hosts - perhaps the installer should ship a bundle or enable using something like certifi if it's installed? AFAIK Apple has deprecated openssl libs as shipped with the OS a long time ago and only support … [View More]

During the alpha phase, features may be added up until the start of the beta phase (2020-05-18) and, if necessary, may be modified or deleted up until the release candidate phase (2020-08-10). Please keep in mind that this is a preview release and its use is not recommended for production environments. Major new features of the 3.9 series, compared to 3.8 Many new features for Python 3.9 are still being planned and written. Among the new major new features and changes so far: PEP 584 <https://www.python.org/dev/peps/pep-0584/>, Union Operators in dict PEP 593 <https://www.python.org/dev/peps/pep-0593/>, Flexible function and variable annotations PEP 602 <https://www.python.org/dev/peps/pep-0602/>, Python adopts a stable annual release cadence BPO 38379 <https://bugs.python.org/issue38379>, garbage collection does not block on resurrected objects; BPO 38692 <https://bugs.python.org/issue38692>, os.pidfd_open added that allows process management without races and signals; BPO 39926 <https://bugs.python.org/issue39926>, Unicode support updated to version 13.0.0 BPO 1635741 <https://bugs.python.org/issue1635741>, when Python is initialized multiple times in the same process, it does not leak memory anymore A number of Python builtins (range, tuple, set, frozenset, list) are now sped up using PEP 570 <https://www.python.org/dev/peps/pep-0570> vectorcall A number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384 <https://www.python.org/dev/peps/pep-0384/>.
