PEP 581 has been updated with "Downsides of GitHub" section
by Mariatta July 2, 2019

July 2, 2019

Hi, I've updated PEP 581 yesterday, adding the "Downsides of GitHub" section. https://www.python.org/dev/peps/pep-0581/#downsides-of-github Other parts of the PEP has also been updated to reflect recent changes to roundup/bpo that happened after PEP 581's acceptance, for example: - ability to automatically close issues when a PR has been merged. This was added to bpo after PEP 581's acceptance. I've also created an issue in devguide so that this can be documented: https://github.com/python/… [View More]

PyAPI_FUNC() is needed to private APIs?
by Inada Naoki July 2, 2019

July 2, 2019

Hi, all. Some functions in cpython are private. These APIs are called from only python executable or DLL. They are not called even from extension modules in stdlib. In this time, I want to keep _PyObject_GetMethod private. https://github.com/python/cpython/pull/14015#discussion_r293351734 As far as I know, it is used to expose the function from DLL user on Windows. So I think when the private function is not intended to be called from outside of DLL, it should not use PyAPI_FUNC. Am I … [View More]

Building Standalone Python Applications with PyOxidizer
by Gregory Szorc July 1, 2019

July 1, 2019

Hey Python developers, I just published the initial release of PyOxidizer - a utility for producing self-contained, potentially single file executable Python applications. You can read more about it at https://gregoryszorc.com/blog/2019/06/24/building-standalone-python-applica… I wanted to draw this list's attention to it because I think PyOxidizer could have significant implications for the Python community. And the 2nd to final section in the blog post is of particular relevance to CPython'… [View More]

Python 3.7.4rc1 (and 3.6.9rc1) cutoffs ahead, now set for 2019-06-17
by Ned Deily June 30, 2019

June 30, 2019

https://discuss.python.org/t/python-3-7-4rc1-and-3-6-9rc1-cutoffs-ahead-now… A reminder: it is time for the next quarterly maintenance release of Python 3.7. The cutoff for **3.7.4rc1** had been scheduled for this coming Monday (2019-06-10) but many of us have been focused on feature code off for 3.8.0, which just took place a few days ago (yay!). So, to give us all a bit more time to attend to 3.7.x matters, I have moved the code cutoff a week, to **Monday 2019-06-17** by the end of day AOE. … [View More]

Championing PEP 467
by Elias Zamaria June 28, 2019

June 28, 2019

Nick Coghlan, I'm thinking about what you said, over a year ago, about finding a new champion for PEP 467. I think it would be a privilege to work on something like that, which may be used by millions of people over a period of years or decades. However, I have decided that I no longer have the time or interest. This PEP has been open but delayed for years. It was originally written in 2014 (apparently with the expectation that it would be included in Python 3.5). My initial attempt to … [View More]

bug(?) - unexpected frames being skipped in extract_stack with closures
by Ed Peschko June 25, 2019

June 25, 2019

all, I'm writing a function meant to print out the context of a given function call when executed - for example: 1. def main(): 2. 3. _st = stack_trace_closure("/path/to/log") 4. _st() 5. _st() would print out /path/to/file.py:4 /path/to/file.py:5 for each line when executed. Basic idea is to create a closure and associate that closure with a filename, then run that closure to print to the log without needing to give the filename over and over again. So far so good. But when I … [View More]

EuroPython 2019 sprints
by Steve Dower June 25, 2019

June 25, 2019

Hi all Just letting everyone know that I signed up any core devs who are going to be at EuroPython to run sprints :) (including myself, since I'll be there) Like PyCon US, the sprints at EuroPython will attract many first-time contributors, so it will be helpful to have as many people who understand our workflow around to help out. We might also be able to get some of our own contributions done. For those who didn't hear, the EuroPython Society is offering a grant for core developers … [View More]
