Why does the Contributor Agreement need my address?
by Joseph C. Sible 10 Sep '18

10 Sep '18

I'm used to signing CLA's that require nothing beyond a name and a check box. When I went to sign the PSF Contributor Agreement so I can submit a PR for CPython, I was surprised to see that it wants my address. Why does the Python Software Foundation need this, especially when nobody else does? Joseph C. Sible

Workflow blocked on the 3.6 because of AppVeyor; who owns the AppVeyor project?
by Victor Stinner 06 Sep '18

06 Sep '18

Hi, It's no longer possible to merge any change in the 3.6 branch of CPython, because the AppVeyor job fails: https://bugs.python.org/issue34575 It seems like AppVeyor has a build cache and this cache is outdated. I tried to use the REST API but I'm not allowed to invalidate the cache: even the most basic REST API query (list my own roles) fails with: {"message":"You do not have required permissions to perform this action."} Who ows the "python" AppVeyor project? Can someone please give me the administrator permission on this project, so I will be able to invalid the build cache? Moreover, would it be possible to give me the administrator permission on the CPython GitHub project, so I would be able to mark the AppVeyor as optional until the issue is solved (to unblock the workflow at least)? I promise I will not mess up the Python project ;-) Thanks in advance, Victor

Comparisions for collections.Counters
by Evpok Padding 05 Sep '18

05 Sep '18

Hello everyone, According to the [doc][1], `collections.Counter` convenience intersection and union functions are meant to help it represent multisets. However, it currently lacks comparisons, which would make sense and seems straightforward to implement. Am I missing something here or should I send a PR ASAP ? :-) Cheers, E [1]: https://docs.python.org/3/library/collections.html#collections.Counter

Python REPL doesn't work on Windows over remote powershell session (winrm)
by ZHU Xiang 05 Sep '18

05 Sep '18

Hello dears Python devs, I'm taking the initiative of writing to you for a question on Python REPL over Windows remote powershell session (winrm). As we’ve all known, Python REPL works well on local Linux, local Windows, and remote SSH session. But for the remote Windows powershell session the REPL doesn’t work, when I type ‘’python” on the remote session, there’s nothing happened. =================================== Steps to reproduce # 1/ pre-install python on server1 (server 1 is a windows os) # 2/ from a powershell console on server0, type below 2 commands: enter-pssession server1 python Expected behavior # The python >>> prompt appears Actual behavior # Nothing, it is still the powershell prompt =================================== The problem impacts all the python versions and all the windows versions. This make me (and other windows guys) unable to use Python remotely, especially for the Windows Server Core version, which is a headless version (no GUI, so no remote desktop connection), the only way to connect to them is by the remote powershell session. You can imagine the panic if Python REPL doesn’t work over SSH for Linux. Could you please kindly have a look, and tell at least why it doesn’t work ? Thanks. FYI, I’ve also opened a issue on Microsoft Powershell GitHub : https://github.com/PowerShell/PowerShell/issues/7581 Regards, Xiang ZHU

Schedule of the Python 3.7.1 release?
by Victor Stinner 05 Sep '18

05 Sep '18

Hi, Someone asked somewhere (oops, I forgot where!) when is Python 3.7.1 scheduled. I wanted to reply when I saw that it was scheduled for 2 months ago: "3.7.1: 2018-07-xx" https://www.python.org/dev/peps/pep-0537/#maintenance-releases Is there any blocker for 3.7.1? I fixed dozens of bugs in the 3.7 branch since 3.7.0 has been released. I'm ashamed of most of them, since I introduced regressions in 3.7. (If you insist, I can name them ;-)) Note: the latest Python activity of Ned Deily, our 3.7 release manager, was an email sent to python-committers mi-July. Victor

Re: [Python-Dev] Let's change to C API!

I know this probably isn't the correct place to bring it up, but I'm sure that CPython itself could benefit from using Cython. For example, most of the C extensions in Modules/ could be written in Cython.

Cipher implementation (such as AES) in standard library
by 大野隆弘 04 Sep '18

04 Sep '18

Dear all, Have we tried cipher implementation includes AES as a standard library in the past? https://docs.python.org/3.6/library/crypto.html if possible I want to try to implement AES because famous 3rd party library is not maintained and general cipher programs should be used for multiple purpose.Though the implementation is tough, I believe this should be worth to it. In my case, I want to use AES implementation for zipfile module. Thanks and Regards, --------------- Takahiro Ono

Python 2.7 EOL date
by Collin Anderson 03 Sep '18

03 Sep '18

Hi All, Sorry if this has been mentioned before, but I noticed the Python 2.7 EOL date was recently set to Jan 1st, 2020. My understanding was Python releases get 5 years of support from their initial release, and Python 2.7 was extended an additional 5 years. Python 2.7 was originally released on 2010-07-03, and with an original EOL of 2015-07-03. Extended 5 years, shouldn't the EOL be 2020-07-03? Also, this statement is a little unclear to me: > Specifically, 2.7 will receive bugfix support until January 1, 2020. All 2.7 development work will cease in 2020. This statement makes it sound like bugfixes end on Jan 1st, but seems to leave open the possibility that security fixes could continue through the year. Thanks! Collin
