- improving snippet handling in the docs (huge amount of files to be converted from C++ to Python)
+
  - Final solution of qApp embedding [https://bugreports.qt.io/browse/PYSIDE-571 PYSIDE-571]. After a long Odyssey of breaking solutions, qApp macro works now as expected with embedding.

==== 11. October 2018 ====
+
==== 6. June 2019 ====
- Qt for Python 5.12 will be first official release
+
  - Summer holidays affecting releasing? Any estimate when we would have:
  -> Python developers have a guarantee to have source/behavior compatibility
+
    - Qt for Python 5.13.0 (Qt still on RC0)
  -> Exception: - no BC/SC statement for libshiboken and libpyside
+
    - Qt for Python 5.12.4 (in the next few weeks)
                - XML schema may change as well
+
  - discussed options how to sign wheel content
  -> expectation: later releases of Qt for Python will commit on the exceptions above
+
  - cross compilation of Qt for Python (work in progress)
- 5.12 branch was created and hooked into CI
+
    -> investigating options on how to achieve that in an easy way
- lots of discussions on how to solve the deployment use case across platforms
+
  - fixed build on CentOS
- wheel separation patches up on code review
+
  - https://bugreports.qt.io/browse/PYSIDE-1017
  -> new wheels: shiboken2, pyside2 (need new project on pypi)
+
  - https://bugreports.qt.io/browse/PYSIDE-1016
  -> users wanting to build their own bindings should currently build shiboken from source
+
  - https://bugreports.qt.io/browse/PYSIDE-1024
- added ability to test build-able example (the script-able C++ examples)
+

    - however very likely any use case for schema would require user to link against libpyside/libshiboken
+
  - Qt for Python 5.12.4 release
  -> libpyside & libshiboken -> no BC or SC promise possible
+
    - patches are accumulating
  -> pure Python application usage (relying on Qt compatibility) -> compat promise given
+

   -> Qt Charts
 
  -> MediaPlayer
 
  -> TabBrowser
 
  -> TextProperties (declarative)
 
- further progress on the build scripts

==== 01. March 2018 ====
 
- 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)

  - Finally got libclang to be deployed into packages
 
  - 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]
 
  - 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]
 
  - Fixed rpath handling for QtWebEngineProcess when creating standalone packages on macOS [https://bugreports.qt.io/browse/PYSIDE-605 PYSIDE-605]

- Havent's merge [https://codereview.qt-project.org/#/c/220083/ this new patch] because we should be 200% sure it's properly working.
 
- Working on a few bugs [https://bugreports.qt.io/browse/PYSIDE-106 PYSIDE-106] [https://bugreports.qt.io/browse/PYSIDE-570 PYSIDE-570]
 
- 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.
 
 
 
==== 15. February 2018 ====
 
- CI broken, 5.6 & dev branch broken, 5.9 just got working again
 
- first TP will be 5.11 based (needs 5.11 git branches, 5.6 branch goes into cherry-pick mode, 5.9 branch remains main target)
 
- more modules added to doc, qt3d & qtquick has some special handling

- 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

==== 1. February 2018 ====
 
- Continued work on documentation [https://bugreports.qt.io/browse/PYSIDE-363 PYSIDE-363], fixed static pages, add more modules, fixed parameters to qdoc, images
 
- The GettingStarted wiki is getting better, besides a cleaning it a bit
 
  - moved the topics around to have guidelines by supported platform (''a la Qt'')

    - solved unicode problem
 
    - reduced the patches to be minimal (avoid many #ifdef's, use a verbose macro name if possible)
 
    - 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.
 
  - [https://bugreports.qt.io/browse/PYSIDE-595 PYSIDE-595]
 
    - Started experimenting
 
    - 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.

  - another patch on top to fix OpenGL integer types on mac / Linux (GLuint64, GLint64)
 
  - 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
 
  - added additional OpenGL2 core example

    - requires adoption of HeapTypes
 
  - QML tutorial updates
 
  - Doc snapshots being prepared
 
 
 
==== 11. January 2018 ====
 
- 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/

  - minor doc fixes
 
  - documenting examples
 
 
 
==== 4. January 2018 ====
 
- multi pyside packages (not easy to do)
 
- renaming Pyside to "Qt for Python"
 
  - quite challenging due to implied import and lib changes
 
  - alias for existing imports would be beneficial
 
- discussion around existing function test
 
  -> working assumption is that we ignore added function and check for existing base line only
 
  -> effort too large to maintain every single new addition
 
- discussed issues around concurrent existing Qt builds while building pyside (potential cross leakage)
 
- various fixes to doc generation steps (see [https://bugreports.qt.io/browse/PYSIDE-363 PYSIDE-363])
 
- discussed need for good examples as part of documentation
 
  -> considered options to cleanup and remove need for submodule

- Pyside CI broken (timeout for tests is zero)
 
  - Pyside provisioning scripts are very fragile
 
  - 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
 
- [https://bugreports.qt.io/browse/PYSIDE-516 PYSIDE-516] further investigation how to deal with void* APIs

==== 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

  => 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

  - the outcome has to be check once everything merged
 
  - upcoming clang dependencies in shiboken introduces new requirements for Coin
 
  - clang changes to be dealt with after pyside branching
 
- clang
 
  - first complete bindings generation with Qt 5.6 and Qt 5.9

- no update on 2nd February 2017 (next week)
 
 
 
==== 19 January 2017 ====
 
- PYSIDE-315
 
  - a possible fix is pending, some minor performance improvements are still possible
 
  - caused by different signal/slot ordering in Qt4 and Qt 5
 
- COIN
 
  - issues on 10.8 and 10.9 platforms should pass now

- 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

- 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

  - 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

  - 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

==== 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 ====

  -> 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

- started to write up documentation on how to deploy with pyinstaller
  - finding quite a few issues when using pyinstaller on Windows (and particular Python 2)
  - macOS & Linux less problematic
- worked on documentation issues (like missing links for easier browsing)
- investigated issues where shiboken didn't handle C++ namespaces across modules
- handle nullptr usage properly in docs
- more translation of C++ snippets to Python (is a never ending task as there are thousands of C++ snippets)

21. March 2019

- Qt for Python 5.12.2 release activities
 - some bugs and general CI issues kept delaying the generation of the final release wheels
 - most bugs were related to pyinstaller and other deployment tools
 - one last cxfreeze bug being integrated
 - next/subsequent set of wheels will be 5.12.2 release
- Lots of installer related discussions in the team
 - question is which installer/deployment tool to use/recommend
 - current decision is to provide guides/documentation for at least fbs and pyinstaller
- review of project's current release practices (in particular in the area of QA)
 - no outcome at this stage
- addressed issues in dev branch related to changes in Qt dev branch
- Qt for Python team joined Qt doc team to talk about ways how to improve Qt for Python docs

14. March 2019

- Fixed broken documentation formatting; added deprecation information
- QTBUG-74424 5.13 Release blocker affecting doc generation occurred
- PYSIDE-932/PYSIDE-942: The embedding patch is mostly
  working, but needs some refinement to be complete:
  - The .pyc generation contradicts the Limited API and must be changed to 
    use source code.
  - The code isolation must be made explicit and complete, so that installers 
    don't recognize that there is something.
    Right now this was done in the wrong direction.
  Not much code and time necessary, just fixing the right bits.
- PYSIDE-934 The Buffer protocol for Python 2 needed a special flag to be compatible.                 
- Added more features for the Python project wizards on QtCreator https://codereview.qt-project.org/#/c/255686/
