==== 01. March 2018 ====
===24. August 2023===
- automatic snapshot process almost in place (pending reviews) (RTA to follow)
- general bug fixing (including build and version problems)
- most community Pyside1 pages point to official Pyside 2 (Qt for Python) wiki pages
- [https://bugreports.qt.io/browse/PYSIDE-595 PYSIDE-595] - Heap Type conversions ongoing
- documentation improving
  -> class diagrams being generated
  -> missing links and references
  -> dependencies to qdoc bugs
  -> snapshot process in works
- added support for scoped enums in pyside
- Important things discussed:
  - PySide2 versioning (current proposal WIP patch at https://codereview.qt-project.org/#/c/221767/)
    - Do official releases follow Qt branch names? -
      -> yes (minor release of Pyside is bound to same minor release of Qt
      -> patch level version may differ
    - Will we have snapshots, and if so, will they be uploaded to pip? How will we handle snapshot versions?
      -> tentative yes, if public pip server supports snapshots Pyside should be good citizen
    - alpha / beta / RC versioning?
      -> Pyside should follow the Qt schema
    - Probably need to take into account PEPs for versions pushed to Pypi.
    - Shiboken / PySide2 versions in sync?
      -> yes, they should be in sync
    - Will we specify a version for 5.6 branch?
      -> yes, but no packages being made
    - Are we sticking to the package name PySide2, but follow Qt 5.x versions as PySide2 versions?
      -> Pyside2_5.11.0 as in https://codereview.qt-project.org/#/c/221767/
  - Do we want to deploy msvcrt dlls into Windows packages?
    -> needs more research - is it really needed ?
  - Do we want to ship debug symbols for Qt inside the PySide2 packages?
    -> not for now
  - Do we want to ship debug Qt shared libraries for macOS packages? (not possible on Windows, not applicable on Linux afaik).
    -> not for now
  - How will the pip upload process look like? Manual uploads? Who takes care of it?
    -> Qt release team will take care of it
  - Current branching policies:
    -> 5.6 branch stops being merged into 5.9 (after pending patches have merged) -> cherry-pick mode
    -> 5.9 is base line for patches and being forward merged to 5.11
    -> no packages from 5.9 & 5.6 (interested parties need to get it from git)
    -> 5.11 becomes branch for first TP
    -> dev is feature development
    -> all first TP release related patches go to 5.9 (and 5.11 subsequently)


==== 22. February 2018 ====
*General
- dev branch is still/again broken in CI, seems like pyside issues
**New board on JIRA to reflect our work clearly https://bugreports.qt.io/secure/RapidBoard.jspa?rapidView=262&view=planning.nodetail&issueLimit=100
- changes to create automatic snapshots out of CI is still under review
**Qt Meetups are starting to popup in Berlin and other countries! we might join some of them.
- Numerous small fixes to the [https://bugreports.qt.io/browse/PYSIDE-363 doc] generation, significantly bringing down the number of documentation warnings
**Discussions around improving the Qt Creator experience and UI creation in general.
- Massaged build rules to improve built packages
**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.
  - Removed unnecessary _utils.py file [https://bugreports.qt.io/browse/PYSIDE-600 PYSIDE-600]
*Infra & Releases
  - Changed wheel package names to contain both PySide2 version and Qt version against which it was built [https://bugreports.qt.io/browse/PYSIDE-613 PYSIDE-613]
**Commercial LTS 5.15.15 to be released soon.
  - Finally got libclang to be deployed into packages
**6.5.3 scheduled for the first week of September
  - Improved build process not to copy unnecessary symlinks and duplicating libraries when creating wheel (so that you don't get 3x size increase because of 3x number of WebEngine libraries) [https://bugreports.qt.io/browse/PYSIDE-495 PYSIDE-495]
*Bugs & Features
  - Fixed wheel package names to contain correct minimum deployment target with which macOS was built with (on further analysis, this will need further improvement) [https://bugreports.qt.io/browse/PYSIDE-612 PYSIDE-612]
**QIODevice::read(char*, qint64) functions are removed, but they are useful for the asyncio story. Discussion on if it's worth exposing them.
  - Fixed rpath handling for QtWebEngineProcess when creating standalone packages on macOS [https://bugreports.qt.io/browse/PYSIDE-605 PYSIDE-605]
**More changes related to QtAsyncIO are ready for review.
- Added CMake build rules for scriptable application example [https://bugreports.qt.io/browse/PYSIDE-597 PYSIDE-597]
**PYSIDE-2417 overflow issue was fixed
- Investigated and fixed a heap corruption bug in a test that caused constant crashes on macOS CI runs
**[ot] i18n in the Qt framework
- Reduced number of warnings when running shiboken to create user bindings (like scriptable application example) [https://bugreports.qt.io/browse/PYSIDE-587 PYSIDE-587]
**PYSIDE-2418 connection issue with python overloads
- [https://bugreports.qt.io/browse/PYSIDE-595 PYSIDE-595]: Making slow progress, still debugging. It's a difficult process, but assumption is that it will work.
**6.6 documentation has some issues due to the QtGraph new module
- Havent's merge [https://codereview.qt-project.org/#/c/220083/ this new patch] because we should be 200% sure it's properly working.
**PYSIDE-2423 connecting signals to python callable doesn't properly work - trying to find a proper solution
- Working on a few bugs [https://bugreports.qt.io/browse/PYSIDE-106 PYSIDE-106] [https://bugreports.qt.io/browse/PYSIDE-570 PYSIDE-570]
**PYSIDE-2424 Installing shiboken in a non-standard way discussion - it might not be properly fixed.
- One of the bugs [https://bugreports.qt.io/browse/PYSIDE-611 PYSIDE-611] was valid only for 5.6, but I noticed a strange behaviour on 5.9, so I will keep working on it, even after we move 5.6 to cherry pick mode.
**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.
**PYSIDE-2421 webengine issue was discussed, it's an Qt/C++ chromium issue.
**CMake FindPython patches are still being worked out, the wrong interpreter is being found.
**patchelf removal is causing some issues with cross compilation.
**qtpip works continues.

- Looking through previous EuroPython talks to write a proposal for this year.         
- Working on a few bugs (fixed a couple related to objects references),               
  - that sadly will open new issues with memory management. A further analysis on this matter could improve the current memory leaks on PySide.                         
- Trying to "organise" a little the typesystem XML files.                             
- Working on [https://bugreports.qt.io/browse/PYSIDE-104 PYSIDE-104] that ended up being a general issue on PySide about a proper verification between slots and signals arguments, to find the best match.
- Merged a few build related changes in 5.6
  - Pending change for [https://bugreports.qt.io/browse/PYSIDE-593 PYSIDE-593]

- Investigated some macOS build related aspects for package release
- 5.6 CI is unblocked, but 5.9 CI is blocked due to qtbase issues (version bumping)
- [https://bugreports.qt.io/browse/PYSIDE-560 PYSIDE-560] waiting for view
- [https://bugreports.qt.io/browse/PYSIDE-595 PYSIDE-595] work ongoing, not ready yet
- [https://bugreports.qt.io/browse/PYSIDE-363 PYSIDE-363]  Documentation: Fixed images, fix handling of qdocconf files  that contain several modules. Looking at snippet resolution.
- Problems with Qt3D due to refactoring of Qt3Dextras in 5.10. Pushed  [https://codereview.qt-project.org/#/c/219105/ patch] suggestion.


==== 1. February 2018 ====
*Bugs & Features
- Continued work on documentation [https://bugreports.qt.io/browse/PYSIDE-363 PYSIDE-363], fixed static pages, add more modules, fixed parameters to qdoc, images
**Investigating on PyPySide MI segfault postponed but on To-Do list [https://bugreports.qt.io/browse/PYSIDE-1991 PYSIDE-1991]
- The GettingStarted wiki is getting better, besides a cleaning it a bit
**[https://bugreports.qt.io/browse/PYSIDE-2404 PYSIDE-2404] More Progress in Lazy Initialization
  - moved the topics around to have guidelines by supported platform (''a la Qt'')
***the optional __getattr__ in module objects was successfully implemented (but is seldom used)
  - have received feedback and trying to add more information
***lazy init of Enums is probably no more needed, covered by the import scheme below
- Addressed bugs:
***most common cases like "from PySide6.QtWidgets import QLabel" supported by another __import__ override
  - [https://bugreports.qt.io/browse/PYSIDE-34 PYSIDE-34]
***Keep your fingers crossed, testing starts today
  - [https://bugreports.qt.io/browse/PYSIDE-264 PYSIDE-264]
**[https://bugreports.qt.io/browse/PYSIDE-2419 PYSIDE-2419] QLocale::language() returns wrong on macOS.  
  - cleaning a bit Shiboken's XML files.
***Caused by QLocale infrastructure which looks at Info.plist inside the Python interpreter macOS bundle.
  - [https://bugreports.qt.io/browse/PYSIDE-560 PYSIDE-560]
***Working on a hack fix after consulting Tor Arne and Eddy.
    - ported to 5.9, extended to 18 header files
**Pacthelf removal - cross compilation breaks. Working on a fix.
    - solved unicode problem
**[https://bugreports.qt.io/browse/PYSIDE-2421 PYSIDE-2421] - QWebEngineView.print() - rerouted to Qt
    - reduced the patches to be minimal (avoid many #ifdef's, use a verbose macro name if possible)
***But, might requires an ownership fix in Shiboken once [https://bugreports.qt.io/browse/QTBUG-116052 QTBUG-116052] is resolved
    - made everything compile but one announced file: "object.h" depends on the heaptypes solution ([https://bugreports.qt.io/browse/PYSIDE-595 PYSIDE-595]). Removed WIP status,review pending.
**Research - use the .debug files provided by the Qt installer to debug from VSCode.
  - [https://bugreports.qt.io/browse/PYSIDE-595 PYSIDE-595]
***Saves time from not building Qt everytime
    - Started experimenting
***Still ongoing
    - turned out that the signature extension barfed because it could no longer find the type "__name__". The function PyType_Type.tp_new needs to be called to provide the "ht_name" attribute that is used in heaptypes.
**QtAsyncio: Implementation of asyncio.Server (one open question remains - asyncio API and Qt API don't always match as cleanly as desirable).
- solving the attribution file issues.
- Pending patches to fix libICU issues
- Pending patches to fix OpenSSL issues [https://bugreports.qt.io/browse/PYSIDE-599 PYSIDE-599]
- Pending patches to deploy libclang library for shiboken

- Pending patches to reduce barrage of warnings [https://bugreports.qt.io/browse/PYSIDE-587 PYSIDE-587]
- Pending patch for adding CMake build rules for the scriptable_application example (useful as a reference on how to use shiboken for custom bindings) [https://bugreports.qt.io/browse/PYSIDE-597 PYSIDE-597]
- Old 5.6 CI integration issue fix, but a new issue appeared that was fixed for 5.9 and dev, but still blocks 5.6
- Updated the qml basics tutorial


==== 25. January 2018 ====
===10. August 2023===
- Pyside not renamed

==== 18. January 2018 ====
*General
  - macOS framework fix (should ignore qt4 system headers)
**
  - another patch on top to fix OpenGL integer types on mac / Linux (GLuint64, GLint64)
*Infra & Releases
  - Fixed so that PySide 5.6/5.9 is not linked against the Python shared / static library (this was wrong because the symbols need to be picked up by the dynamic loader from the python interpreter itself). http://bugreports.qt.io/browse/PYSIDE-522
**
  - Completed move of examples from pyside-examples.git to pyside-setup
*Bugs & Features
  - added additional OpenGL2 core example
**Patchelf removal only partially possible because of using patchelf on prebuilt Qt binaries.
  - fixed testrunner (these silently failed since forever) https://codereview.qt-project.org/#/c/216732/
***For Qfp binaries patchelf removal under review. MacOS issue being fixed. This is needed for Android.
  - fixed issues whereby wrong QObject ctors were selected
**Shiboken module cmake installation bug fixed.
  - removed webkit from Pyside2 build 
**Progressing with Android C++ to Python callback, now that Qfp binaries could be loaded on startup.
  - talk about Windows specific instructions for [[PySide2 GettingStarted|Getting Started Guide]]  
**Further investigating on PyPySide MI segfault [https://bugreports.qt.io/browse/PYSIDE-1991 PYSIDE-1991]
  - Qt3D issues in Qt 5.10 fixes
**[https://bugreports.qt.io/browse/PYSIDE-2404 PYSIDE-2404] Progress in Lazy Initialization
  - clazy warning fixes
***the new dual registration is done and builds the base for concrete lazy init
  - Stable ABI work (started to convert implementations) (see [https://bugreports.qt.io/browse/PYSIDE-560 PYSIDE-560])
***lazy init of Enums postponed because
    - requires adoption of HeapTypes
***an undocumented optional __getattr__ in module objects makes it much easier to lazy-load whole classes, first.
  - QML tutorial updates
  - Doc snapshots being prepared


==== 11. January 2018 ====
===3. August 2023===
- multi pyside packages (not easy to do)
  - unlikely to achieve until TP
  - a package per python release (3.4, 3.5, 3.6, 2.7)
  - package per platform (win 32bit|64bit, mac, linux)
  - long term task to convert to reduced Python API (to support multi 3x packages)
  => have to cut some targets: one 3x and 2.7 release
  -> create doc howto to encourage custom builds for not covered platform combo
  -> do we need commercial for release
- pysinstaller is an installer
  -> deployqt tool not necessary
  -> documentation required stating the option
- rename import options
  - rename via alias possible
  -> still an issue when looking up particular types but probably manageable 
  - renaming option: Qt4Pyton, QtPy, QtPython, Python4Qt, Qt
- example shift
  - https://codereview.qt-project.org/#/c/215900/
- Basics for doc generation toolchain
- Issues where cmake picks up platform Qt references where it should use a Qt custom install
- Qt3D bindings still under progress
- [https://bugreports.qt.io/browse/PYSIDE-34 PYSIDE-34] & [https://bugreports.qt.io/browse/PYSIDE-560 PYSIDE-560]
- Documentation
  - minor doc fixes
  - documenting examples


==== 4. January 2018 ====
*General
- multi pyside packages (not easy to do)
**New reports board
- renaming Pyside to "Qt for Python"
**QtCreator support
  - quite challenging due to implied import and lib changes
**Integration cycle on gerrit overview
  - alias for existing imports would be beneficial
*Infra & Releases
- discussion around existing function test
**CI down next Monday for a few hours
  -> working assumption is that we ignore added function and check for existing base line only
**First tests on linux arm64
  -> effort too large to maintain every single new addition
**Preparing 5.15.15 Commercial LTS
- discussed issues around concurrent existing Qt builds while building pyside (potential cross leakage)
**qtpip first trials on the CI
- various fixes to doc generation steps (see [https://bugreports.qt.io/browse/PYSIDE-363 PYSIDE-363])
*Bugs & Features
- discussed need for good examples as part of documentation
**Async research continues, new things are being discovered while is being developed
  -> considered options to cleanup and remove need for submodule

==== 21. December 2017 ====
===20. July 2023===
- Issues building for Windows for Python 2 and 3 (on coin)
- discussing potential pyside demo/example for RTA purposes
- Continued work on macOS / Qt 4 header issues, progress is there
  - breaks GL signature test on Linux, needs further investigation
- Investigated PyInstaller (potential option to deploy apps written with Pyside)
  - seems to work almost out-of-the-box for deploying PySide apps
- Investigated building one package compatible with multiple Python 3.x minor versions
  - not possible currently, will require a lot of work, possibly not feasible
  => we need to build 3.4,3.5,3.6 * win, linux, mac packages = 9 packages
  => 3 more for each platform and Python 2.x
  => commercial packages?
- lots of discussions and fixing of doc tool chain (qdoc in dev currently broken)
  - adding documentation has begun in earnest
- continued work on PYSIDE-578

*Bugs & Features
  - delivery channel for Pyside binaries (pip server? local install from qt account download?)
**Implementing transports and protocols of asyncio API
- investigate options to have sth like pyinstallqt (pysinstaller is a possibility)
**Lazy importer still under development. Ongoings:
- final keyword support by shiboken
***necessary to register all types without creating them
- Qt3D bindings patch close to completion - > requires some Qt changes in 5.9.4 or later Qt
***turning all PyTypeObject into PyTypeObject valued functions
- fixing pyside build issues when encountering Qt 4 headers on macOS
***quite hard because deeply buried in the generated code
- PYSIDE-578 (testing procedure/testrunner) -> adds heuristic to adapt to failure rates (flakiness handling)
  - concerns that running all tests 5 times adds too much load on the CI (test runs needed)


==== 30. November 2017 ====
===13. July 2023===
- packaging related coin changes
- last weeks merges between 5.6 and 5.9+ blocking coin have been fixed (in particular on RHEL)

    1.) qdoc generates WebXML -> Shiboken converts WebXML to ReST (used to work in Qt 4 days)
    2.) qdoc is lib which creates AST - > shiboken uses the AST to generate ReST
    3.) \pyside to document python classes (lots of documentation effort and not ReST integratable)
    4.) minimalistic approach is to merely link to the Qt object class reference (python specific docs are somewhat separate

==== 5 January 2017 ====
===16. February 2023===
- COIN update
  - COIN changes merged (no further patches pending)
  - need to run an integration test
  - issues related to different build platforms still to be expected
- Continue with clang
  - backtracking a bit (reusing some node API's during parsing but otherwise use clang to populate the tree)
- test blacklisting reviewed (some removed - mostly signal related ones, one new regression)
- regressions in QtQuick were worked around (caused by recent Qt Quick changes)
- issues with macos framework style includes in Qt
- PYSIDE-315 debugging ongoing, very hard to track down
  - was it a regression from a previous Pyside release (e.g. Qt 5.4?!?
- hard-copied Qt 5.4 based headers still in existence
  - updated needed but would shut Qt 5.4 users out
