Dooble releases-Qt6

[Rich Walsh]

https://doc.qt.io/qt-6/qtextcodec.html might help...

scratch this, QTextCodec is part of qt5compat which can't be used in building qt6core

I hate to run people around with a bunch of almost-but-not-quite-right binaries that we could easily test ourselves before release. Could we please take this development process offline until we do get it right? I'll send you and Dave an email.

This build, ftp://dry@ftp.os2voice.org/dooble/dooble-2024.12.06-Qt6.zip is the same as the previous build except it has fixed window title for non-English titles, best shown with Remy's page, https://remydodin.levillage.org/en/.Other languages depend on the window title's font having the correct glyphs. Example, https://ru.ecomstation.ru/, which here shows the Russian in the title bar.
Currently Qt6 is missing the code that allows fixing the window list.
Also need https://smedley.id.au/tmp/qos2-20241205.zip and https://smedley.id.au/tmp/qt6core-20241206.zip
Thanks to Rich for coming up with the patches and Paul for building the Qt6 DLL's.

[Dave Yeo]

Also, for both Qt5 and Qt6, the environment variable "QT_PM_CP" can be used to change the code page that the window title uses. To quote Rich,

Paul, setting the CP to 1208 in the environment should also enable
you/someone  to test the QT6 sample apps without having to change
a line of code.

Code page 1208 is UTF8.

 Thanks Dave, Rich and Paul for this fix! Works well here with Dooble using either QT6 or QT5.

 Dave, in regards to OpenGL, Paul said QT needs either gl2.h or egl.h to build OpenGL functions. You had made a build of PortableGL whose samples worked well here so I was wondering if PortableGL provided either of those files...

How do you use this setting ?

I added as environment variable :
'set QT_PM_CP=1208'

This makes Dooble not start

 

[Dave Yeo]

Latest Dooble itself does not need the setting, it is for other Qt apps or if you want a different code page with Dooble.
Still it shouldn't crash and doesn't here. Look in popuplog.os2 for a exception report and try running "dooble.exe 2>&1 | tee dooble.log" without the quotes and see if dooble.log has anything interesting in it.

No, PortableGL nor any other OpenGL library I've looked at have those headers.

I give it a new try and start !
May be I had not enough storage during previous test. System was rebooted since 

[Remy]

Hi !

I just had a system froze using Dooble qt6.
I don't know if this could help but I had a strange CPU% utilisation !

Regards
 

[Remy]

Ok, I think having found, I left automatic CPU speed increase (Turbo boost) enable under BIOS.
Now disabled.

Seems more stable. One silent close but this time, i've got more informations into stdout logs:
[94:39:1208/234436.722000:ERROR:indexed_db_factory_impl.cc(595)] Failed to GetDBSizeFromEnv: IO error: /000039.log: File not found

Profile corruption? If you remember the page that triggered the exception, you could go to \home\.dooble\WebEnginePersistentStorage\IndexDB and move the entry out of the way and see if that helps

I deleted all files and no silent close but about freeze, it is as bad as before I change turbo boost bios option.
When on youtube, trying to open a new tab or moving the page cursor, sound goes into a loop and system freezes...
Reboot required.

The first creating problem is the audio but it seems also been impacted by the mouse movement etc !  driver issue or interrupt priority handling?

Latest release, https://github.com/dryeo/dooble/releases/tag/2024.12.31 or ftp://dry@ftp.os2voice.org/dooble/dooble-2024.12.31-Qt6.zip.
OS/2 changes, use utf8 in the Window Title as well as show dots for unprintable characters in the Window List. Requires Paul's latest build.
