    • A different approach might be needed
    • Our current testing infra is not enough to simply write tests for nogil python, and many hiccups have been found.

    • The TCP protocol was initially implemented
    • New tests were provided to continue the development in the future (using an asyncio event loop)

  • To catch-up with the cmake improvements to our build system (orthogonal to the scikit-core research)
    • this will allow us to properly have the module as projects configures to be find them.
    • In the future, we will simplify our CMakeLists.txt for hybrid applications, a lot!
  • iOS research continues
    • Cross compiling is still an issue due to the shared/static
    • OpenGL issue has a workaround, but still researching on the underneath

22. May 2025

• General Topics
  • Some updates from PyConUS
  • Qt Bridges: We might participate at Akademy
  • Qt Bridges: We got an accepted talk https://ndctechtown.com/
  • Qt WS: Talk recording might be delayed to be public.
  • PyCon IT: Going there to give a talk
  • Windows on ARM is getting more attention from other companies.
    • There is currently an issue with OpenGL (not being in Qt, hence not in Qt for Python)
    • FreeCAD requires opengl for some reason :S
• Infra & Releases
  • 5.15.19 commercial LTS was released
  • 6.9.1 postponed by a regression
  • 6.5.9 still pending (security fix)
  • We might evaluate uv for CI
• Bugs & Features
  • We will work on being more compatible with uv (shiboken issue finding dlls)
  • iOS research: managed to cross compile the project, but there seems to be an issue still when trying to use it from XCode side of things. We might need to try the setup.py approach rather than CMake.
  • API deprecations that needs to be handle: missing functions on the typesystem and in some test cases. QtXml (QDomDocument) missing new function needs to be added as well (overload issue). Some works needs to be done in the examples as well.
  • Thoughts on limiting the disable gil solution that we have at the moment. There has been a lot of crashes and issues by implementing our own locking mechanism.
  • QtAsyncIO has been brought up in some community discussions, so we might work more on this. There are many NotImplemented issues around, that would be good to have.
  • Qt Python Scripting: Aiming for 6.11, and to find a place to distribute it. Due to the limitation of virtual functions, it's mostly about doing a bit of scripting on top of the Qt/C++ applications. Does it justify it to be a new Qt module? maybe we could use Qt solutions. We need another person to check the API, to have a second opinion.
    • There are some ideas of virtual-function override from pybind11, but then we would require shiboken ownership mechanisms, that will increase dependencies (and size)
    • Release process of qt-modules is strict.
  • PYSIDE-2193 variance in QML Properties. QVariant/PyObjects issues were found and fixed.
  • Got interest of doing RTA internally, that's generating more reports.
  • CMake relocation files shipping that are not being included anymore (headers or cmake files), but got required by Qt Bridges.
  • New cmake variables are being required for Qt Bridges.
  • Message handler changes are still pending for CI issues.

    • For uploading, you need to turn-on developer mode, which raises a message of "privacy being reduced"
