QTBUG-118578 notes

Some bug reproductions and notes on QTBUG-118578

Undocking tabbed widget from floating window creates empty redundant window

Screencasts showing broken behavior with https://codereview.qt-project.org/c/qt/qtbase/+/516878

Patchset 27

Undocking a QDockWidgetGroupWindow from QMainWindow, followed by undocking one tab from the group window (keeping tab in a dragging state), followed by re-docking that tab to any location will result in the tab you are docking to instead be docked to the QMainWindow in the same position that the group window was docked. See screencast 516878-27-redock-to-floating-dockwidget-docks-qmainwindow.webm

Determining mirrored Qt submodules that are not mirroring properly
I encountered an issue with Qt repositories that are mirrored, but not all submodules being mirrored properly.
This makes it impossible to clone and build new Qt releases. These notes help discover which submodule repositories are not syncing properly with the code.qt repositories:
For further testing to verify that all the needed submodules are mirrored properly for a given release tag, I test the following way:
```
$ git clone https://mirror.host/foo/qt5.git -b v6.5.2
$ ./init-repository --force --module-subset=default,-preview,-qtnetworkauth,-qtpurchasing,-qtquick3d,-qtlottie,-qtcharts,-qtdatavis3d,-qtvirtualkeyboard,-qtwebglplugin,-qtactiveqt,-qtconnectivity,-qtcoap,-qtmqtt,-qtopcua,-qtquicktimeline,-qtquickeffectmaker,-qtquick3dphysics
# (failures will occur if the needed submodule refs (commits) are not present in the submodule repositories)
$ for subm in $(git submodule status | awk '/^+/ {print $2}'); do git submodule update $subm; done

Apple debugging tips

  1. Create a blank Xcode project for the purpose of debugging your app, if it was not built with Xcode.
  2. Select your executable you wish to debug using Debug->Debug Executable... or Debug->Attach to process.
  3. You can modify startup parameters for the app using the scheme, accessible at Product->Scheme->Edit Scheme....
  4. To load debug versions of libraries, like the Qt libraries, set the environment variable DYLD_IMAGE_SUFFIX to _debug which will load the the debug versions of the Qt libraries. You can set this in the Arguments tab of the Scheme editor.
  5. In Scheme editor, make sure that the Document Versions ☐ Allow debugging when browsing versions checkbox is unchecked - it defaults to on. Without doing this, you will often have applications failing on startup because Xcode inserts command line options to the application that the app is not expecting.
  6. Make sure that the .dSYM files are located adjacent to the .frameworks and/or .dyld libraries.
  7. Running `image l
