Do we want to keep pythonmac-sig?
by jack.jansen＠cwi.nl May 26, 2025

May 26, 2025

Folks, I just got a mail from the Python mailman server admin that they will shortly be upgrading the mailman server, and the question is whether to keep the Pythonmac-SIG mailing list alive or archive it. Personally I don’t mind archiving it, we’ve had about 2-4 messages per year over the last years. But on the other hand, it isn’t a lot of work to maintain (at least not for me), I basically have to throw away the spam once a week or so. What do people think? -- Jack Jansen, <Jack.Jansen(a)cwi.nl>, http://www.cwi.nl/~jack If I can't dance I don't want to be part of your revolution -- Emma Goldman

ANN: PyObjC 11.0
by Ronald Oussoren Jan. 15, 2025

Jan. 15, 2025

I'm happy to announce the 11.0 release of PyObjC, slightly delayed from the normal major release in October. This release has two major features: Support for the macOS 15.2 SDK, including new bindings for the frameworks MediaExtension and DeviceDiscoveryExtension Experimental support for GIL-less operation in the free-threaded build of Python 3.13 The latter feature is an important reason for the delay: Supporting GIL-less operation required reworking parts of the internals of PyObjC, both to rely on other locks than the GIL and to avoid CPython APIs that are known to be problematic when the GIL isn't present ("borrowed references" for anyone familiar with the CPython API). Free-threaded support is experimental at this point in time and has seen only limited testing for multi-threading. I've also focussed on getting the basics right, and have not worked at optimizing free-threading support. Expect improvements in future releases. With PyObjC 11 I'm dropping support for Python 3.8, given that that's gone out of support by the CPython team. Finally, there's a number of bug fixes and smaller features mentioned in the changelog at https://pyobjc.readthedocs.io/en/latest/changelog.html Ronald -- Twitter / micro.blog: @ronaldoussoren Mastodon: @ronald@blog.ronaldoussoren.net.

Survey on PyPI Metadata: Why Authors and Maintainers Link (or Don’t Link) Their Libraries to Code Repositories
by Alexandros Tsakpinis Aug. 3, 2024

Aug. 3, 2024

Dear PyPI author, tl;dr: We are researching why PyPI authors link (or don't) link their libraries to code repositories. Therefore, please participate in our 5-minute survey: https://forms.office.com/e/b5uvsPdJLF We have a question regarding your library called bdist_mpkg published on PyPI where you are assigned as responsible author. More information about your published library can be found in the attached .txt file. As you probably know, it is possible to attach project URL information to a library published on PyPI. Adding, for instance, the associated repository URL to a library enables others depending on that library to analyze present and historical maintenance and development activities in more detail. To better understand why authors decide to assign a valid repository URL, but also to learn about the factors why some don't link their repositories, we kindly ask you to answer the following survey with your published library(ies) in mind. The survey should take about 5 minutes. If you are interested in participating in the survey you can access it under the following link: https://forms.office.com/e/b5uvsPdJLF Thank you for your time and participation! You will not receive any further e-mails regarding this survey.

Trouble building tkinter for Aqua
by Matthew Dixon Cowles Dec. 8, 2023

Dec. 8, 2023

I'm trying to compile Python 3.12.0 from source on a new ARM MacBook. I haven't had any trouble except with the tkinter module. I've built Python from source any number of times before on Linux and macOS, but previously always with X11. (For the moment, I'm just doing an ordinary Unix build, not a Framework build.) I've built Tcl and Tk (with --enable-aqua) and the tests run. (Tk seems unhappy with a few of the window manager tests but they don't seem like a big deal and nothing blows up.) The libraries are in /usr/local/lib: $ ls -l /usr/local/lib/libtk8.6.dylib -r-xr-xr-x 1 root staff 1572304 Dec 6 22:50 /usr/local/lib/libtk8.6.dylib $ ls -l /usr/local/lib/libtcl8.6.dylib -r-xr-xr-x 1 root staff 1558656 Dec 6 17:58 /usr/local/lib/libtcl8.6.dylib But when I run configure, I get: checking for stdlib extension module _tkinter... missing At the bottom of configure's output, I get: configure: WARNING: pkg-config is missing. Some dependencies may not be detected correctly. So I've tried hand-hacking the Makefile, replacing: MODULE__TKINTER_STATE=missing with: MODULE__TKINTER_STATE=yes MODULE__TKINTER_CFLAGS= MODULE__TKINTER_LDFLAGS=-ltk8.6 -ltcl8.6 But then make gives me: [ERROR] _tkinter (/usr/local/src/Python-3.12.0/build/lib.macosx-14.1-arm64- 3.12/_tkinter.cpython-312-darwin.so) is missing which suggests that the build process didn't try to build that module. Is there some trick that I'm missing? Some additional bit of fiddling I need to do to get the build process to try to build tkinter? Thanks! Regards, Matt

Python Launcher Pops Up When Py-based App Is Running
by James Greenham Oct. 9, 2023

Oct. 9, 2023

Hello, I run macOS Mojave with Python 2.7. I have an old Dashboard widget (last modified in 2009) that appears to use Python as well. The widget captures the full Safari web-page. It works seamlessly on earlier macOS systems but hangs in 10.14. The widget's core functions constitute code of the script that I'm pasting in this message. The problem is that as soon as the execution reaches the image processing stage it gets stuck which manifests by Python Launcher popping up in Dock and is trying forever until I quit the launcher that force-quits the widget showing the error icon. The issue seems to originate in the doGrab handler (module or whatever the correct Python term fits the definition) immediately following the print "Processing Image..." line: it's the message the widget displays at getting stalled. I( checked that Python 2.7 is installed in the default location at /usr/bin. However, I have the binaries idle3, idle3.10, pip3, pip3.10 in /usr/local/bin. Is that remedied? The script's environment set to python, i.e. to python 2.7 so that shouldn't be the encumbrance. Am I correct? #!/usr/bin/env python # -*- coding: utf-8 -*- # OR: # coding=utf-8 __version__ = "0.6" # # Based on Paul Hammond's webkit2png script - make screenshots of webpages # http://www.paulhammond.org/webkit2png # # Modified by Paulo Avila for the Page Capture widget # # The original source code (v0.5) belongs to Paul Hammond (see notice below). # Any and all code added after is Copyright (c) 2009 Paulo Avila. # # Modification Log by Paul Avila # # 2009.04.21 - Changed almost all the output messages in order to behave properly with my Page Capture widget # 2009.04.21 - Added function headers # 2009.04.21 - Properly flush the output buffers so that messages display immediately # 2009.04.21 - Changed encoding of this file to UTF-8 # 2009.04.25 - Updated how files are named: "<domain> > <file>.png" # 2009.04.25 - Files are now named with the full URL excluding protocol (http://) and arguments (...?*) # # Copyright (c) 2009 Paul Hammond # # Permission is hereby granted, free of charge, to any person obtaining a copy # of this software and associated documentation files (the "Software"), to deal # in the Software without restriction, including without limitation the rights # to use, copy, modify, merge, publish, distribute, sublicense, and/or sell # copies of the Software, and to permit persons to whom the Software is # furnished to do so, subject to the following conditions: # # The above copyright notice and this permission notice shall be included in # all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR # IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, # FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
