Qt for Python Development Notes: Difference between revisions

Revision as of 16:02, 27 January 2023

General
- Hackathon in TQtC
- The WebAssembly PySide Team was almost doubled in size (+1 brain, +1 hand)
Infra & Releases
- Windows signing to be improved.
- LTS releases into oss repo: some issues appeared but will be merged soon.
Bugs & Features
- PYSIDE-1994: De-virtualization of Shiboken embedded Python files is now an option controlled dynamically by SBK_EMBED
  - PYSIDE-1019: A dormant __feature__ initialization timing problem was fixed while implementing de-virtualization
- PYSIDE-1735: De-coupling of old and new enums was started
- PYSIDE-1564: Debugging of multiple inheritance continues
- Fixed some bluetooth functions in PySide6.
- Low Energy Scanner Example
- PYSIDE-2194: Progressing with this. Definitely a thread issue which allow-thread doesn't seem to fix.
- Possible solution for problems with PySide6 inside conda (compat package with qt6.conf file), but investigating if best solution

General
- Next week is Hackathon, meeting will be shorter
- Discussion on how to gather information, and sharing material around Qt for Python
Infra & Releases
- 6.5 RC planning -> feature freeze for PySide
- 6.4.2 was released last Monday
- CMake Jumbo builds issue with Windows signing
- LTS branches to land in pyside-setup soon
Bugs & Features
- Async examples: addressing memory leak and cpu usage due to the event loop interactions
- Review conda packaging story and PySide6
- De-virtualization of Python files: still some issues
- Incompatibility with pywin32: __feature__ related when trying to check if the ext module uses PySide. Also related to an issue with the inspect module.
- Installing PySide6.support via CMake (was previously not considered)
- Work continues on the multiple inheritance issues related to classes based on QObject
- locate issues related to to* methods
- std::array support in shiboken (still in progress)
- fixing imports in matplotlib examples
- adaptation to 6.5
- splitting shiboken generator source to its own
- Android deployment works - tested on Widget applications
- Fixing QTBUG-109510 leading to discovering issues with certain functions in PySide6. Being fixed.

General
- Next monday CI maintenance
- OKRs
Infra & Releases
- 5.15.12 LTS, 6.2.7 LTS released
- Open Source LTS releases to be moved to the pyside-setup
- 6.4 CI hanging, issues on lts-5.15 due to Python
- 6.4.2 to be release in the following days
Bugs & Features
- PYSIDE-1931 SQL issue regarding allow-thread
- helping 6.5 translations
- Adaptations with 6.5
- QSharedPointer -> std::shared_ptr attempt
- research on adding std::span into shiboken
- PYSIDE-2160 properties qml types issues
- Tutorials language review
- Android research continues
- QTBUG-109510 BTLE issue on pyside

+**Alternative approach to Anaconda issue: Register internal qt6.conf with site-packages prefix (still WIP).
+**WIP: Implement class QtAsyncIoEventLoop(asyncio.AbstractEventLoop) that wraps around Qt's event loop to enable Qt + asyncio.
+**Memory leak with current asyncio example (or space leak?)
