* Bugs & Features
* Bugs & Features
** Work on support for clang 16, which changes behavior quite a bit
** Few new type hints issues from 6.7.0 release, needs to be address on 6.7.1
** Fixed [https://bugreports.qt.io/browse/PYSIDE-2284 PYSIDE-2284] issue with NoneType

** PYSIDE-2675 Lazy loading issues with trees of polymorphic classes.
*** first approach made things less effective
*** The impact of the solution was reduced a bit, by disabling the feature for special multiple-inheritance cases
*** New idea on 'groups' that be handled differently, so we have group or classes grouped and dependant

* General
** Bug fixing week.
** Qt 6.6.3 Library split broke our release, so we provided 6.6.3.1 as a fix.
** Qt 6.7.0 also had an issue with a binary incompatibility change on QtAudio and QAudio
** Maybe we implement a simple channel of communicating this details, in order to avoid breakage [maybe architect meetings]
** Qt Creator 13 creates venvs automatically. This needs to be revisited to avoid multiple environments to be created.
** New epics with brainstorming ideas.
* Infra & Releases
** 6.7.0 was released, we found a couple of issues we are trying to solve, and 6.7.1 will soon be released due to a binary compatibility break, and other small breakage.
**  5.15.17 commercial LTS to be release next week.
** QtDS packages a bit delay due to CI errors.
** Qt Installer (Maintenance tool) has  still some issues with the structure.
* Bugs & Features
** Adding new Qt tools to the wheels (wrappers)
** PYSIDE-2602 special virtual function research
** PYSIDE-2669 designer issue
** PYSIDE-2675 Addressing the lazy import issues that were found in 6.7.0
*** Studying the possible solution, but it needs to consider other cases as well.
*** the *-import handling seems to be related, and affecting the mro content, duplicating some entries.
*** the type discovery handler might be related as well
** Still working on the qml 825 bug issues.

** nogil research was positive, and most of our test work. It would require for us to modify the generator for each function/module.
** singleShot timer implementation (to use underlying c++ impl) - still an issue with a context object, and a signal as a functor. A new QObject::connect might handle the situation. More changes to come in order to fix newly discovered issues.
*** mandelbrot example works and improves its performance around 3.5 times.
** Android: using the master branch on python-for-android, and other changes related for macOS deployment.
** Python 3.12 will include an incompatibility due to the changes in the type generation
** PYSIDE-2597 optimization for the deployment procedure
*** https://github.com/python/cpython/issues/60074#issuecomment-1430115581

** 6.7 adaptation still in progress (many changes from Qt)
** It will be possible to install pyside6 in conda environments starting from 6.4.3 and 6.5

** LTS tags cannot be pushed to community repo (permissions), hopefully in this week.
** Decouple of the commercial wheels in order to have a finer granularity and simpler tree on the Qt Installer (Maintenance Tool)

* Bugs & Features
* Bugs & Features
** Android research in progress, looking good :)
** VS Code will use .flake8 (formerly setup.cfg) file for configuration once merged
** A solution was proposed to fix the usage of PySide6 in conda environments: still needs tweaks to work, mainly related to an internal qt.conf that's loaded at runtime.
** PYSIDE-2575: Added a new argument to QtAsyncio to configure whether the QCoreApplication at the core of QtAsyncio should be shut down when asyncio finishes (requested by user).
** PYSIDE-2222 custom widget plugin, load with uic crash
** SingleShot timer issue: Slight "complexity explosion" because correct implementation for one case requires implementation of QObject.connect overload with context arguments (and we implement QObject.connect ourselves, see PySide::qobjectConnectCallback).
** PYSIDE-2201 was fixed: introducing weak references into the SignalInstances.  
** Scripting: code simplification, and massage it to a Qt module.
** PYSIDE-79 was possible to solve (from PYSIDE-68 solution). Still needs to some documentation to be written.
** Documentation updates to fix issues we had.
** PYSIDE-2221 research on future compatibility with NoGIL Python https://github.com/colesbury/nogil https://peps.python.org/pep-0703/
** Unity build some issues when building without.
** https://github.com/blueloveTH/pocketpy also interesting
** 6.7 updates, adapting some warning messages
** QTBUG-99313 related issues
** macOS permissions: made an example to work (for deployed apps) - patches incoming
** Android wheels provisioning and configuration in order to generate the base-wheels.
** armv7 complications due to an upstream find_python command.
** Lazy initialization: re-wrote approach from scratch, to reduce the patches to one that can be analyzed easily. Some complications with this approach that needs to be improve. It can be tried with https://codereview.qt-project.org/c/pyside/pyside-setup/+/496118
*** https://peps.python.org/pep-0690/ was rejected, but the idea can be implemented per-module
** Moving entry_points declaration to pyproject.toml from setup.py
** Drop the bdist_wheel steps from the CI (old wheels)
** Started working on split commercial wheels, wheels for QtDS and examples on QtCreator.

2024

18. April 2024

  • General
    • Bug fixing week
    • PyConDE (Mon-Wed next week)
    • Planning a workshop for TQtC solution engineers (internal)
    • Possibility to include shiboken into the Axivion infra

  • Bugs & Features
    • Few new type hints issues from 6.7.0 release, needs to be address on 6.7.1
    • QtAsyncio issue related to Task groups. Tricky, because it can be related to Qt Events.
    • PYSIDE-2629 Adding more Qt-tools to the wheels
    • PYSIDE-2622 Adding a new option to the deploy tool (exposing an option from Nuitka)
    • PYSIDE-2675 Lazy loading issues with trees of polymorphic classes.
      • first approach made things less effective
      • The impact of the solution was reduced a bit, by disabling the feature for special multiple-inheritance cases
      • New idea on 'groups' that be handled differently, so we have group or classes grouped and dependant
    • 825 qml bug is still around
      • PYSIDE-2676 seems to be a new approach to fix it
    • A few customer bugs made it the bug fixing week.

    • Qt 6.7.0 also had an issue with a binary incompatibility change on QtAudio and QAudio
    • Maybe we implement a simple channel of communicating this details, in order to avoid breakage [maybe architect meetings]
    • Qt Creator 13 creates venvs automatically. This needs to be revisited to avoid multiple environments to be created.
    • New epics with brainstorming ideas.
  • Infra & Releases
    • 6.7.0 was released, we found a couple of issues we are trying to solve, and 6.7.1 will soon be released due to a binary compatibility break, and other small breakage.
