** PyEnum: Story finished API-wise. To come are optimizations and removal of old enum code.
**Android permissions API: Adapt more C++ examples
** Signature test simplified and activated, again. Signatures are now always tested.
**Couple more cleanups and additions to pyside6-android-deploy
** PyEnum: Working on documentation
**More manual testing of pyside6-android-deploy. Need to write more integration (mocks) for Android deployment.
** Profiling signature module. Rewrite parts in C? cProfile and line-profiler (3.9)
**Final cleanup and resolving tests for python-for-android Qt for Python patch
** QFormLayout.takeRowResult() should now finally be supported if the test is indeed right ([https://bugreports.qt.io/browse/PYSIDE-1312 PYSIDE-1312])
**[https://bugreports.qt.io/browse/PYSIDE-2468 PYSIDE-2468] -requestPermission() on macOS. Tricky scenario similar to [https://bugreports.qt.io/browse/PYSIDE-2419 PYSIDE-2419]
** Fixed an old problem with random values in QFormLayout.getItemPosition() for row == -1.
**asyncio's requirement to use ThreadPoolExecutor keeps screwing us over, but resolution close
** Android story requires jumping through some hoops on Windows (several parts of the toolchain are Linux only).
*** Toolchain can run on WSL, but problems for Android Virtual Device -> adb redirection over TCP as workaround.
*** adb redirection over TCP not yet supported by Qt Creator, complicating some things - might be easy to fix, investigating.

**New board on JIRA to reflect our work clearly https://bugreports.qt.io/secure/RapidBoard.jspa?rapidView=262&view=planning.nodetail&issueLimit=100
**Qt Meetups are starting to popup in Berlin and other countries! we might join some of them.
**Discussions around improving the Qt Creator experience and UI creation in general.
**There has been some motivation from Qt/C++ to use more CMake in projects (like for resources), which is negatively affecting the Python projects, due to the lack of CMake in the Python projects.
*Infra & Releases
**Commercial LTS 5.15.15 to be released soon.
**6.5.3 scheduled for the first week of September
*Bugs & Features
**QIODevice::read(char*, qint64) functions are removed, but they are useful for the asyncio story. Discussion on if it's worth exposing them.

**Next Wednesday 10am: session about Shiboken + QtScrypt status
**PYSIDE-2419 locale issue on macOS due to the Info.plist that python includes that overrides the QLocale settings. A bug report was filed upstream, and a workaround is suggested.

**QVariant issue related to Enums was at the end fixed.
**[https://bugreports.qt.io/browse/PYSIDE-2404 PYSIDE-2404] More Progress in Lazy Initialization
**Enabling automatic testing on VSC requires __init__.py files in all directories
***the optional __getattr__ in module objects was successfully implemented (but is seldom used)
**We might add a .vscode/settings.json for development purposes
***lazy init of Enums is probably no more needed, covered by the import scheme below
**The Windows Debug tutorial will be expanded :)
***most common cases like "from PySide6.QtWidgets import QLabel" supported by another __import__ override
**Deployment: struggling with formatting of libraries
***Keep your fingers crossed, testing starts today
**https://bugreports.qt.io/browse/PYSIDE-1996 seems to be a pyi issue
**[https://bugreports.qt.io/browse/PYSIDE-2419 PYSIDE-2419] QLocale::language() returns wrong on macOS.
**https://bugreports.qt.io/browse/PYSIDE-1735 Finished the implementation, starting with the documentation
***Caused by QLocale infrastructure which looks at Info.plist inside the Python interpreter macOS bundle.
**https://bugreports.qt.io/browse/PYSIDE-1970 __slots__ issue might be related to the usage of old python versions
***Working on a hack fix after consulting Tor Arne and Eddy.
**Adapting changes from QtCore like Q_DECLARE_METATYPE and changes to Q_ARG/invokeMethod
**Pacthelf removal - cross compilation breaks. Working on a fix.

**Research - use the .debug files provided by the Qt installer to debug from VSCode.
***Saves time from not building Qt everytime
***Still ongoing
**QtAsyncio: Implementation of asyncio.Server (one open question remains - asyncio API and Qt API don't always match as cleanly as desirable).

    • Qt Meetups are starting to popup in Berlin and other countries! we might join some of them.
    • Discussions around improving the Qt Creator experience and UI creation in general.
    • There has been some motivation from Qt/C++ to use more CMake in projects (like for resources), which is negatively affecting the Python projects, due to the lack of CMake in the Python projects.
  • Infra & Releases
    • Commercial LTS 5.15.15 to be released soon.
    • 6.5.3 scheduled for the first week of September
  • Bugs & Features

    • CMake FindPython patches are still being worked out, the wrong interpreter is being found.

17. August 2023

  • Bugs & Features
    • Investigating on PyPySide MI segfault postponed but on To-Do list PYSIDE-1991
    • PYSIDE-2404 More Progress in Lazy Initialization
      • the optional __getattr__ in module objects was successfully implemented (but is seldom used)
      • lazy init of Enums is probably no more needed, covered by the import scheme below
      • most common cases like "from PySide6.QtWidgets import QLabel" supported by another __import__ override
      • Keep your fingers crossed, testing starts today
    • PYSIDE-2419 QLocale::language() returns wrong on macOS.
      • Caused by QLocale infrastructure which looks at Info.plist inside the Python interpreter macOS bundle.

    • Research - use the .debug files provided by the Qt installer to debug from VSCode.
      • Saves time from not building Qt everytime
      • Still ongoing
    • QtAsyncio: Implementation of asyncio.Server (one open question remains - asyncio API and Qt API don't always match as cleanly as desirable).

10. August 2023

  • General
  • Infra & Releases
  • Bugs & Features
    • Patchelf removal only partially possible because of using patchelf on prebuilt Qt binaries.
      • For Qfp binaries patchelf removal under review. MacOS issue being fixed. This is needed for Android.

    • Progressing with Android C++ to Python callback, now that Qfp binaries could be loaded on startup.
    • Further investigating on PyPySide MI segfault PYSIDE-1991
    • PYSIDE-2404 Progress in Lazy Initialization
      • the new dual registration is done and builds the base for concrete lazy init
      • lazy init of Enums postponed because
      • an undocumented optional __getattr__ in module objects makes it much easier to lazy-load whole classes, first.
