== Pyside for Qt 5.x ==
 
The Pyside 2 project aims to provide a complete port of [[PySide]] to Qt 5.x. The development started on [https://github.com/PySide GitHub] in May 2015. The project managed to port Pyside to Qt 5.3, 5.4 & 5.5. During April 2016 The Qt Company decided to properly support the port (see [https://groups.google.com/forum/#!topic/pyside-dev/pqwzngAGLWE details] ).
 
This wiki page tracks the progress of PySide for Qt 5.x development and provides further information concerning the effort.
 
=== Tools ===
The following tools are used to develop PySide2:
* Bug tracker: https://bugreports.qt.io/browse/PYSIDE

==== 14. September 2017 ====
- Coin
  - 5.6 testing is back online (5.9 target unblocking pending a merge)
  - Packaging of Pyside started to become a discussion topic
      - Standard PIP deployment
      - Separate delivery via the usual Qt account channel
- void* support has a pending patch (https://codereview.qt-project.org/#/c/205124/ and related example https://codereview.qt-project.org/#/c/205272/)
- Documentation work ongoing

  - Qt's own  provisioning is interfering when e.g. Pyside relevant tools get changed by Qt
  - new ideas and redesign is likely to be needed
- New Bindings: QRegularExpression, QVersionNumber, QUuid,
- Discussions around Documentation for pyside
  - couple of options for generation pipeline
    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

==== 18. May 2017 ====
- Coin
  - Win nodes didn't run the cleanup functions -> test failures due to artifacts -> no solution yet
  - Clang issues persist and this must be addressed in the broader scope of Qt/qdoc depending on libclang too
    -> until this point in time the setup is a manual one for pyside/5.9+
- merge of psyide repositories -> no objections against the plan in the community
  -> merge will happen in the next few days (pyside.git, pyside-setup.git and shiboken.git become one repo)
  -> examples, wiki and tools will remain as they are
- QOpenGL* porting continuing
- qttext2speech ported to Pyside2
- failing QML tests in Qt 5.9 based Pyside
- PYSIDE-510 - introspection solution in the works
- Qt World Summit Berlin 2017 (talk for Pyside being handed in)
 
==== 12. May 2017 ====

- Fixed a small regression in 5.9 with building on macOS after some cmake changes that happened in 5.6
- Implemented, tested, reviewed and committed the multimedia widgets examples
- documentation from Pyside1 days can not be generated anymore
  -> new approach required using exiting Qt5 doc tools

  => may have to change once we come closer to the final release ->
  => fine as long as we are in heavy development mode
  - discussion around Ubuntu and OpenSuse configurations
  - minimal cmake requirements not met on all distros
    - 5.6 only be build using RedHat 6.6
    - 5.9 builds have updated Linux distros -> may be able to obtain a new cmake version without hacking the standard toolchain
- QtMultimedia and QRaster* API bindings further completed
- added tests and examples for the above bindings/APIs
- PYSIDE-510 (required for simplified and more generic testing of bindings)
- PYSIDE-504 work is ongoing

  - next steps in priority -> run tests on 10.8/10.9 and get Linux running
- PYSIDE-79 regression fixed as well (some interaction between PYSIDE-315 & PYSIDE-79)
- PYSIDE-462 to be looked at next
- clang parser work progressing
 
==== 12 January 2017 ====
- PYSIDE-315
  - sorting of slots/signal connection changed on Qt side and Pyside side has not caught up
  - had similar connection issues on the QML side, need to investigate whether there is a connection
- PYSIDE-79
  - caused a regressions (not yet investigated)
- fixed OpenGL types not being recognized on MacOS (partly fixed)
- API's with shared/smart pointers in Qt don't work
  - has potential long term effects and investigation has started into the reasons
- Refactoring shiboken in preparation for clang
- COIN currently runs tests with namespaced Qt
  - short term fix to exclude namespaced Qt builds with Pyside (broken on MacOS 10.9)
  - other failures: missing libraries on MacOS (10.11), missing provisioning on Windows, cmake issues on 10.10
  - unknown state on Linux (current Redhat too old)
- Prioritization after status round:
  - PYSIDE-315 to be investigated based on recent signal/slot patches for QML
  - Smart pointer issues reduced in priority to provide space for PYSIDE-315 & PYSIDE-79 regression
- verify that COIN runs testrunner (not just building Pyside)
  -> not yet verified since we are still failing builds in COIN
 
==== 5 January 2017 ====
- 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
 
==== 22 December 2016 ====
- lots of discussions around the COIN patches
  - source archive setup being under review
  - Qt 5.6 provisioning patches merged
  - CI uses Python 2.7 at this stage
- clang C++ parsing continues
- fix of some Pyside unit tests (now have a clean slate again)
- finished QtQuick port
- some overflow problems have been fixed in shiboken
 
==== 15 December 2016 ====
- COIN changes pending for testing infrastructure
    -> https://codereview.qt-project.org/177136 (Pyside change)
    -> https://codereview.qt-project.org/176968 (Coin change)
    -> https://codereview.qt-project.org/179662 (Provisioning changes)
    -> https://codereview.qt-project.org/179663 (Provisioning changes)
- waiting for COIN development team to review/accept the pending changes
- no update in PYSIDE-315 (under investigation)
- Flushed out a couple of shiboken, QML, qml example bugs
- Some bugs related to parser delayed until clang parser task done (https://bugreports.qt.io/browse/PYSIDE-322)
- most basic shiboken API extractor test to pass (global enumeration test)
- some trouble with int size data types
    -> Python 2 & 3 are different and the relevant C++ data types are yet again different from platform to platform
 
==== 8 December 2016 ====
- COIN patches pending approval
  - Windows provisioning reviewed
  - Linux, Pyside, COIN itself
- Clang changes progressing, comparing AST tree from old parser and clang
- PYSIDE-79 done
- PYSIDE-315 under investigation
- QtQuick patches taking shape (some template magic and function pointer
  features in Qt cannot be parsed by shiboken)
 
==== 1 December 2016 ====
- COIN
- PYSIDE-79 there seems to be a final work around (https://codereview.qt-project.org/#/c/176374/)
    - fixing a few tests in the process
- clang update
  - dumping AST, identifying the required info
  - work in progress...
- problems with global static QObjects on the Qt side calling back into Python during app exit
  - may require some changes on the Qt side
 
==== 24 November 2016 ====
- automatic COIN triggering for submodules work in progress
  - several discussions on this topic this week
- Clang investigation (what library to use)
- fixing bugs on Qt side for Pyside
- Qt QML support almost done, work will continue with Qt Quick
- PYSIDE-79 work story continues
  - reference counting not quite accurate but point of deallocation of ref count not identifiable
 
==== 17 November 2016 ====
- Pyside team suffering from sickness -> not much progress this week
- Pyside-79 fix had a lot of negative side effects (breaking existing tests)
  - internal object reference counting is the predominant issue at hand
  - continue to work on the bug (no resolution yet as delayed due to sickness)
- COIN some progress but still open discussions on branching policy required
 
==== 11 November 2016 ====
- PYSIDE-79 being fixed
- PYSIDE-315 to be addressed
- Shiboken and Clang
  - familiarizing with clang and its parser's inner working
  - added experimental qmake project definition for shiboken (makes work in Qt Creator easier)
- Qt QML on Pyside work progressing
- work on COIN did not progress due to conflicting priorities inside COIN development
 
==== 3 November 2016 ====
- working through the QML stack esnuring all required API's are exported (https://codereview.qt-project.org/#/c/175682/)
- small build system patches
- PYSIDE-79 work progressing
- OpenGL support fixed (PYSIDE-314)
- COIN issues
    - repo interdepencies not working yet, suggestion under discussion and to be implemented
    - most license checks have been fixed
    - Qt 5.6 based Pyside to skip check
    - after branching for C++11 work the dev branch should work from license check perspective
    - eventually the entire CI needs to run through (more hidden problems could be hidden)
- Started working on C++11 compliant parser for shiboken
    - libclang will be used
    - first target is to replace the AST tree implementation
    - requires clang setup in the CI
 
==== 27 October 2016 ====
- Work on WebKit/WebEngine support
- Further work on [https://bugreports.qt.io/browse/PYSIDE-431 COIN] support
- Planning meeting

==== 20 October 2016 ====
- [https://bugreports.qt.io/browse/PYSIDE-355 Qt Quick support] submitted
- [https://bugreports.qt.io/browse/PYSIDE-314 QtOpenGL support] submitted
- Further work on [https://bugreports.qt.io/browse/PYSIDE-431 COIN] support, license headers
==== 13 October 2016 ====
- Qt CI update
  - Coin changes have merged but integration not yet working
  - Qt CI enables on Pyside side merged
  => COIN integration fails with license issues
  => requires review of license conditions for all files, some files are not even relicensable
  => skipping license check for now, most likely to be done later again but requires changes to license check script
  - more issues of interworking between QtCI and Pyside expected (won't be visible until license problems resolved)
  Open issue: does a change in Pyside repo trigger a rebuild of everything?
- Qt QML support progressing and first patches merged
  - serious bugs have been fixed, more complex QML examples are now working
 
==== 29 September 2016 ====
- Coin integration close but not merged
- Bugfixing in particular on the shiboken parser side
- QML/Python binding and tests fixed -> general check all day-to-day aspects of QML are working
- QML examples porting
    -> still some failing tests
    -> Check all QML/Quick class are exported
 
==== 22 September 2016 ====
- Refactored Shiboken, udnerstanding build sequences
- black list for unit tests defined and tested
- fixing of tests
- QML example fixing continued (QML bindings not working)
- Pyside side for COIN done (pending integration checks)
- COIN integration still wip due to long test and retest cycles
- pyside and shiboken repo to be relicensed similar to other Qt products
=> this should address any issues regarding the status of generated code too
==== 16 September 2016 ====
- Pyside side for CI testing ready for testing
- status of COIN side to be determined. Code exists need help from CI team to confirm status.
