22. March 2018
- Topics to cover: - Release process (do we follow Qt?)
15. March 2018
- Fix to create 3.6 Linux wheels under review.
08. March 2018
- msvcrt.dll to be shipped on Windows - wheel snapshots are automatically generated - start with public availability under http://download.qt.io/snapshots/ci/ - snapshots to public pypi server under discussions - discussion on how to increase value of official pyside mailing list http://lists.qt-project.org/mailman/listinfo/pyside - looking at build issues on Windows (improving error handling) - Participation in Python User Group meeting in Berlin (https://www.meetup.com/Python-Users-Berlin-PUB/events/xhqwhpyxfblb/) - PYSIDE-595 - Heap Type conversions ongoing - test bed created for easier development - Documentation -> Managed to make libxml, libxsl an optional dependency falling back to QtXmlPatterns (despite QTBUG-66925) -> Small fixes to doc modifications -> Fix class inheritance diagrams for nested classes
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 - 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
- dev branch is still/again broken in CI, seems like pyside issues - changes to create automatic snapshots out of CI is still under review - Numerous small fixes to the doc generation, significantly bringing down the number of documentation warnings - Massaged build rules to improve built packages - Removed unnecessary _utils.py file PYSIDE-600 - Changed wheel package names to contain both PySide2 version and Qt version against which it was built PYSIDE-613 - 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) 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) PYSIDE-612 - Fixed rpath handling for QtWebEngineProcess when creating standalone packages on macOS PYSIDE-605 - Added CMake build rules for scriptable application example PYSIDE-597 - Investigated and fixed a heap corruption bug in a test that caused constant crashes on macOS CI runs - Reduced number of warnings when running shiboken to create user bindings (like scriptable application example) PYSIDE-587 - PYSIDE-595: Making slow progress, still debugging. It's a difficult process, but assumption is that it will work. - Havent's merge this new patch because we should be 200% sure it's properly working. - Working on a few bugs PYSIDE-106 PYSIDE-570 - One of the bugs 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 - snippet work ongoing - snapshot generation on the agenda - lots of bug fixing e.g.: PYSIDE-104 - PYSIDE-560
8. February 2018
- 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 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 PYSIDE-593 - Pending change for PYSIDE-605 - Merged changes for PYSIDE-603 and PYSIDE-604 - Investigated and attached minimal reproducible example for PYSIDE-585 - 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) - PYSIDE-560 waiting for view - PYSIDE-595 work ongoing, not ready yet - 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 patch suggestion.
1. February 2018
- Continued work on documentation 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) - have received feedback and trying to add more information - Addressed bugs: - PYSIDE-34 - PYSIDE-264 - cleaning a bit Shiboken's XML files. - PYSIDE-560 - ported to 5.9, extended to 18 header files - 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 (PYSIDE-595). Removed WIP status,review pending. - 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. - solving the attribution file issues. - Pending patches to fix libICU issues - Pending patches to fix OpenSSL issues PYSIDE-599 - Pending patches to deploy libclang library for shiboken - Improved documentation about OpenSSL dependency - Pending patches for cleaning up build scripts a bit (logging and refactoring) - Pending patches to reduce barrage of warnings 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) 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
- Pyside not renamed - Releasing preparation - pip packages created by coin - Automated release testing (RTA) (installing pip, launching an example) - final selection of release package targets to be define closer to release (depending on current stable ABI work) - Investigation doc issues when using prefix & shadow builds - Need to identify prime demos/examples - Started to rework Getting Started Guide wiki - Addressed cmake build issues - Handling libICU issues (causing linker issues when importing QtCore) - Continued work on PYSIDE-560 -
18. January 2018
- macOS framework fix (should ignore qt4 system headers) - 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 - fixed testrunner (these silently failed since forever) https://codereview.qt-project.org/#/c/216732/ - fixed issues whereby wrong QObject ctors were selected - removed webkit from Pyside2 build - talk about Windows specific instructions for Getting Started Guide - Qt3D issues in Qt 5.10 fixes - clazy warning fixes - Stable ABI work (started to convert implementations) (see PYSIDE-560) - 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/ - 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 - PYSIDE-34 & PYSIDE-560 - Documentation - 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 PYSIDE-363)
- discussed need for good examples as part of documentation
-> considered options to cleanup and remove need for submodule
2017
21. December 2017
- 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
7. December 2017
- pip wheel installation - adding support for simultaneously python 2 and 3 builds - open issues: test installation towards multi python 3 versions - delivery channel for Pyside binaries (pip server? local install from qt account download?) - investigate options to have sth like pyinstallqt (pysinstaller is a possibility) - final keyword support by shiboken - Qt3D bindings patch close to completion - > requires some Qt changes in 5.9.4 or later Qt - fixing pyside build issues when encountering Qt 4 headers on macOS - 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
- packaging related coin changes - last weeks merges between 5.6 and 5.9+ blocking coin have been fixed (in particular on RHEL) - 5.9 + 5.6 are passing, dev has some private Qt changes which will affect pyside/dev - lots of coin infrastructure issues - RTA test wheels added (install and launch single example) - crash bugs in 5.6 branch reported but not details known yet (waiting for more details) - some discussion what changes should be put to 5.6 vs 5.9 branch - Qt3D bindings started - some changes in qt3d/5.9 required) - shiboken bugs discovered in the process (virtual function guessing & some comparison operators for namespace generated) - small regression related to rpath handling on Linux - open pip wheel issues: - handling of multi Python version wheels - testrunner bugs addressed and reducing flakiness - issues in Pyside when building with gcc 7.x - qdoc from qt5/dev is required for pyside due to webxml support - it is a problem for the pyside/5.9 branch
23. November 2017
- pip wheel support issues on Linux solved (not yet verified)
-> libICU usage on Linux should be enabled via pyside setup script
-> downloaded from qt account download area
- discussion how to do wheel builds for different Qt base lines -> implies to different wheel packages
- need to evaluate how different python versions on various Linux distros impact wheel binaries
- target: 6 wheels (2 per platform for 2.7 & 3.5+ Python)
- OpenGL example
- merge 5.6-> 5.9 attempted
- signature update to match Qt 5.9 ABI/signatures
- plenty of testing flakiness and also test crashes
- improvements to signature tests
16. November 2017
- Build system cleanup. It is now possible to build only a subset of Qt modules per cmd line option - this is not complete and may need further patches - Added QAxContainer, more classes from 5.10 - Preparing to add Qt3D - Removed flaky test - further research on how pip wheels might be used for Pyside - seems to work well on win & macOS - problems on Linux related to libICU (or in general due to different system libraries) - implemented and tested --standalone feature for the main Qt platforms PYSIDE-558 - open question remains how 3rdparty Pyside deployment path might look like - PYSIDE-510
9. November 2017
- Work on simplifying the build system, made it possible to specify a module subset to build - PYSIDE-558 Fixing rpaths and making --standalone work on the 3 platforms. Result: Self-contained binary wheels. Needs Review. - Trying to setup the project for building the docs. I managed to build the rsts from the patch in gerrit but running sphinx on those rsts results in errors about python 2 style code. - PYSIDE-510 work continued
2. November 2017
- Releasing:
- continued work on macOS installer
- binaries must be patched during the install from repo (rpath setting)
- adopting the scripts from Qt for Pyside
- made pip install work on Mac -> would be alternative to online installer approach
- two deployment choices available
- discussions on how void* pointer should be handled, two options on the table
- add additional Pyside module handling such pointers
- add feature to shiboken to transparently add the support to any arbitrary C++/pyside project using shiboken
- documentation snapshot generated
- simplified setup-pyside and related build script options
26. October 2017
- Releasing: - test repo for online installer created (mac seems to deploy) - first evaluation of suggested installer approach on various platforms - Documentation: - Qt doc team joined the effort - first experiences are collected - should new documentation be done in rst rather than qdoc format? - Getting started, General platform requirements and general fixes turning up during generation - PYSIDE-571 received further fixes and reviews - REDHAT not working on Coin (caused by gcc header issues) - other minor improvements
19. October 2017
- Discuss open Pyside 2 release & documentation - Release packaging suggestion - Qt for Python installed via Qt installer and python scripts pointed to module via PYTHON_PATH - create test online repository for Qt installer - follow up how this Pyside installation approach might impact deployment of Python apps using Qt for Python - Linux distros shipping Pyside? (not sure yet either) - coin - breakage in CI provisioning due to competing Python binaries coming from MSVC 2017 - coin template needs updating - PYSIDE-571 work progressing (ready for review) - lots of fixes in Pyside dev branch and - feedback from Qt World Summit: - is Pyside on Android and iOS? - iOS probably out since platform cannot have interpreted code - Scriptable application use case was a sought after feature - qdoc got WebXML patch -> open question which version to use for doc generation across the various pyside versions - add script to support single command to generate documentation
12. October 2017
- no update due to Qt World Summit 2017
05. October 2017
- Qt DataVisualization port has finished including an example - Coin no progress due to pending Qt 5.9.2 release - webxml support being implemented inside qdoc (beginning of the pyside documentation toolchain)
28. September 2017
- 5.6 and 5.9 branches are *finally* enforced by CI - yeeeaaahh - Dev branch is still missing some forward merges before it can be enabled. - port of QtDataVisualization progressing - fixed bugs: PYSIDE-510, PYSIDE-517, PYSIDE-562, PYSIDE-564 - PYSIDE-156 in progress, first example of qApp protection, benchmark of impact ongoing
21. September 2017
- Prototyping and exploring of Pyside packaging options - PYSIDE-510 done and merged - PYSIDE-156 being addressed thanks to PYSIDE-510 - PYSIDE-487 Qt Data Visualization port progressing
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
- WebXML support was added to qdoc - see PYSIDE-363
- inputting the resulting WebXML to shiboken gave promising results
- Qt Creator gain ability to fold away Python license headers
- Signature patch (https://codereview.qt-project.org/#/c/198654/)
7. September 2017
- 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
- PYSIDE-516 further investigation how to deal with void* APIs
-> prototyping ongoing
- PYSIDE-510 redesigned once again (no more internal Python dependencies, Python version independent implementation)
31. August 2017
- 5.9 passes on all platforms but one (10.10 still failing) -> fix for provisioning scripts pending - 5.6 no problems at hand (all passing) - PYSIDE-516 hit a dead end -> fundamental way of passing vertex data (void*) pointer between Python and C++ not addressed yet - PYSIDE-510 complete

03. August 2017
- PYSIDE-510 under code review https://codereview.qt-project.org/198654 - > license issues have to be addressed - > some testing aspects still open (delayed till later on) - > investigation of impact on deployment across multiple python run-time versions required - missing bindings script/wiki page updated: Missing PySide2 bindings - first working array support has been delivered (some adjustments still required), now proceeding to extend for OpenGL PYSIDE-516 - Missing classes in works (e.g. QAbstractnativeEventFilter, QFileLock,....) - > revealed some issues of handling void* pointers
27. July 2017
- Fix for PYSIDE-331 causes lots crashes in auto tests -> more investigation ongoing - coin - since 5.6 is now enforced by Qt CI the focus shifted to the 5.9 branch of Pyside - still encountering build issues on 5.6 though - cmake upgrade for macOS 10.10 - missing virtual env for macOS 10.12 being deployed - msvc 2013 being removed from CI targets - clang on OpenSuSE deployment ongoing - lots of effort went into debugging the above Coin issues - numpy support for 2d array feature development progressing (PYSIDE-354)
20. July 2017

13. July 2017
- coin
- Production coin was updated today and all fixes are finally executed
- 5.6
- macOS 10.11 machines have Python 2.6, which causes test script to fail due its usage of a

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
- looked into the Windows tests failures, and the reason might be related to how we copy around build artifacts, leading to an incorrect folder structure. Coin team to look at it. - 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 - QOpenGL* port to Pyside has started -> missing support for arrays in shiboken - more thorough design discussion needed - Coin - provisioning for clang in Qt CI ongoing: https://codereview.qt-project.org/#/c/192517/10

- discussion around merge policies between 5.9 and 5.6 branch - Linux debug library issues fixed - PYSIDE-488 fixed via workaround - fixed a unit tests - worked on qdoc/html generation in Pyside (failed so far - waiting for qdoc maintainer feedback) - PYSIDE-331 patches merged -> more bugs found in the meantime
6. April 2017
- 5.6 branch created - 5.9 branch to be created as well (easier setup for Qt 5.9 testing in Coin) - Coin - not passing build platforms have been disabled - otherwise COIN passing on 5.6 (except for 2 failing test) -> soon to be enforced - license checker passing in dev - clang changes merged to dev branch (after reviews) - clang provisioning on Coin still missing - for now shiboken is not a generic C++ bindings generator (targeting Qt use cases only) - TODO: enabling the generation of documentation from repos - fixed mixed usage of debug and release build (no debug builds for windows) - [PYSIDE-331] work continuing - fixed, tests are missing
30. March 2017
- Coin - some platforms passing and will be enabled by default - MinGW, some OSX and cross compile targets remain out - will branch pyside dev branches to 5.6, new dev becomes clang branch - regular merges from 5.6 -> dev will start happening - Pyside 5.6 branch will continue to work against Qt 5.6 - need reviews for PYSIDE-323 to merge clang changes - Qt 5.10, 5.9 (on main desktop plawtforms working) - for now the Pyside dev development will be based on Qt 5.9 (to be bumped up later on) - [PYSIDE-331] - in progress - [PYSIDE-156] -
23. March 2017
- Coin - progressing - More tests fixed - wip/clang branch created, will receive Clang parser port with instructions - Refactoring of shiboken, replaced QtXml classes by QXmlStreamReader allowing for stricter error checking
16. March 2017
- Coin - the fixes are still integrating or are under review (no further progress until this is done) - clang parser replacement PYSIDE-323 - most test failures related to clang are fixed - tests ran pretty much through on Qt 5.9 (Windows and Linux - Mac not yet verified) - code cleanups in shiboken - will create feature branch on all pyside repos to get the clang patch series under CI control - merges from regular pyside branches into clang branch will commence - readme required that explains how clang is to be built (if not provided by platform) - [PYSIDE-331] - in progress
09. March 2017
- Coin - lots of changes in Gerrit for Pyside and coin - 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 - some failing unit tests which have to be looked at individually - actual merge depends on pyside branching which in turn depends on recent Coin changes - smart pointer support - patches generally done, gerrit review ongoing - rather large patch - created list of missing bindings in Pyside (Missing Bindings) - mostly class level view, global functions at al not covered - Jira cleanup - PYSIDE-464, PYSIDE-217, Pyside-224 fixed - most bugs reviewed now and valid ~100 bugs were identified
02. March 2017
- Coin
- Coin runs tests on Windows and OSX (some failures in the test - to be investigated)
- Windows provisioning somewhat blocked due to CI issues
- no progress on Linux
- OSX 10.8 ran tests with expected results
- OSX 10.9 has issues due to Pyside not supporting namespace builds of Qt
- clang
- preprocessor has remaining issue
-> with clang compiler but gcc seems OK
-> Qt Core wrapper close to compiling (QHash issues remaining)
- Smart pointer work continues
- some uses cases work, other use cases might remain
- PYSIDE-364 was fixed (patch pending)
- General error review on bugreports.qt.io
- 50% done (prioritized bugs are handled/checked bugs - "done" bugs)
- ran address and leak sanitizer over Pyside which resulted in some worrying cases (need to be addressed going forward)
22. February 2017
- PYSIDE-462 Improved solution approved - PYSIDE-205 Hard-to-detect memory leak plugged - slow memory leak found in shiboken with thousands of false positives - used differential analysis of valgrind output - Clang: Fixed Preprocessor handling (set defines, include paths), got minimal binding tests to pass, now adapting MetaBuilder and PySide to what Clang finds when parsing Qt. Good news: Very little need to set Q_DOC or other magic defines - Coin: Slow progress, currently struggling with provisioning
- extensive bug triaging ongoing in Pyside Jira project
16. February 2017
- Coin (no update - other priorities in release/CI team) - Clang (progressing on pre-processor work) - PYSIDE-315 closed - PYSIDE-462 more review needed - Shared pointer API very slowly progressing (lots of different fixes needed) - QMimeDataBase support added - QUrlQuery support blocked on QDOC defines in Qt sources (shiboken sets the wrong define) - chasing memory leaks (PSYIDE-205) - extensive bug triaging ongoing in Pyside Jira project - confirming and testing the reported bugs (70 of 200 processed) - some smaller bugs were fixed in the process - quite a few bugs were discovered this week while working on the above items, e.g.: - deployment of pyside applications partly broken due to hard-coded install paths in Qt libs - Qt events are swallowed when Pyside error/exception occurs -
9. February 2017
- Clang progressed - pure C++ tests for API extractions are passing (C++ parsing based on clang) - even works with cmake - old C++ preprocessor still to be replaced - working through old preprocessor and checking what magic it did and how clang might be able to replace it - PYSIDE-315 & PYSIDE-462 fixes pending for review - COIN - continue progress an getting more platforms to pass (unblocking one step at a time) - Windows (32bit) and mac are building, Win 64bit still not building - OSX and Windows are stopping in the test runner phase - missing cmake update still on Linux (provisioning update required)
26 January 2017
- PYSIDE-315 - principle fix merged but some minor improvements still pending - Pyside-462 - essentially a feature request as C++ default parameters are not yet supported by Pyside - discussion ongoing how to address the problem - COIN - 10.11, 10.9 & 10.8 build passes - 10.10 still failing during build - Progress on Windows and running into new problems further down the path - Redhat failed to general brokenness of the platform in CI - Ubuntu no further progress - clang parser work progressing - completeness of work is currently measured by passing unit tests - there is a long way to go - see PYSIDE-323 and associated patches for progress monitoring - Fixed regression which prevented Pyside to compile with Qt 5.5.1 - shared pointer support - 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
- 10.11 & 10.10 still have issues
- Windows timeout problem fix in COIN (but no COIN update until 5.8.0 released)
- Linux builds are failing
- Ubuntu 14.04 fails due to cmake issue
- Redhat 6.6 & OpenSuse 13.01 deferred
- current COIN freeze for 5.8.0 release affecting patching of COIN for Pyside
- 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
2016
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)

- 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 COIN support - Planning meeting - Workshop for C++11 support in Pyside (PYSIDE-323)
20 October 2016
- Qt Quick support submitted - QtOpenGL support submitted - Further work on 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. - build system infrastructure improvements in pyside setup - Qt logging now working - and more - Update on bug handling - PYSIDE-88 continuing - PYSIDE-349 (Multimedia ported) - PYSIDE-344 fix pending on codereview - make debug builds of Pyside work (OSX works, Linux has work in progress patch, Windows side awaiting contribution) - QML support work in progress - examples are slowly ported with aim to identify bugs
25 August 2016
- Properly implementing QML experience in Pyside - Unit test fixing - automated CI testing for Pyside - working locally but still failures occurring on various other test machines
4 August 2016
- Additional Pyside examples under review - Fixed warnings coming from Shiboken
21 July 2016
- main Pyside 2 example port done - additional examples to fill gaps are being ported (as per prio list) - CI patches running, but still gaps (should be done by next week) - about 86% of auto test working (failing count of test 80+ auto test) - Project Test Status
14 July 2016
- Pyside 2 examples ported - OpenGL & SVG not working - QtQuick 2 is in strange situation (QtQml depends on QtQuick) - Python 3 realed Unicode handling not working with Qt - QMessageBox hangs - no documentation for any example - lots of warnings when building wrapper - results: https://paste.kde.org/pgje2toyh/mlbqic - COIN setup for pyside https://codereview.qt-project.org/#/c/158336/ - Qt 5.7 still blocked due to missing C++11 support in shiboken - food for ideas: https://steveire.wordpress.com/
7 July 2016
- automated CI testing - patches for Pyside and Qt CI side required - Testing somewhat more complicated due to closed nature of Qt CI - script to port examples to Qt 5 -> https://bugreports.qt.io/issues/?jql=labels%20%3D%20exampleport5 - all examples to remain BSD licensed
