Uggh https://github.com/psmedley/qt6-base-os2/blob/6.8.x/src/corelib/kernel/qeventdispatcher_os2.cpp is going to need substantial rework to get it compiling/building

Made some progress with Qt 6.2.8 webengine over the weekend - seems that https://github.com/psmedley/qt6-webengine-os2/commit/83083b1d2f14d1297b8ac24ae0dfad85e90e2037 allows some pages with light javascript to work  - screenshots in the applications thread.

Promising.... It's even less stable than the 6.2.6  build, but at least some pages with javascript are working...

  Any ideas what Javascript needs to get the webengine working?

I had an idea yesterday after running a diff between 6.2.6 and 6.2.8 -unfortunately the change triggered a substantial rebuilt, so I'm still waiting to see if the change makes any difference...

I updated the core Qt6 libraries to 6.2.10  which was released this week.  The webengine remains at 6.2.6  due to javascript issues.

Many, many moons I liked at nginx, back when it had far less functionality than it does today.

Hey Steven,

This one looks familiar.  Didn't you already patch blink::ParkableImageManager::Instance() to do proper SSE alignment?

TBH I didn't even look at these last night, I was done for the day by the time the build finished. I'll  examine them this evening. It's always possible I missed a patch.

OK I patched around the SSE problems in blink::ParkableImageManager::Instance() - in this case, I just disabled SSE in this source file.

Now pages without V8 load, anything with javascript gives TRPs like the attached. As I recall, this is where I got to with Qt6.4.3 previously. It's hard, as every trp is different....

Most likely due to the changes in platform-os2.cc at https://github.com/psmedley/qt6-webengine-os2/commit/2df03acbb089c8472ca02f7477001780ad095dd0#diff-cc2c94e34243ed90f8fb8d01c931f30835818dc27a48275bb911a144f5bbf065

Now that the 6.2.6 webengine is working ok-ish -  I'm rebuilding the 6.2.8 code which is chromium 102.0.5005.177, using GCC 14. This is similar to the code in Qt 6.4.x.

As I recall,  it compiled OK, but any use of javascript crashed the browser, we'll see what happens. Maybe a fresh review of the v8 code will highlight some problems <shrug>

<sigh> dooble crashed immediately, simplebrowser gives crashes like  the following...

What do you think about this ?
https://github.com/bitwiseworks/qtwebengine-chromium-os2/issues/27

What in particular? It's a closed ticket,  this code is included in the Qt6 port.

It priority problem was described.

Q: I only get trp files using the LIBCN0 as suggested. Is it as expected ?

If these are silent exits - then yes. Silent exit is caused by  the webengine code calling exit(). The modified libcn0.dll  modifies  the exit() code to force an exceptq dump.

The TRP will include "Cause:    Program requested an Exceptq debug report" whereas a 'normal' exceptq will show something like "Cause:    Invalid execution address 00000000"
