You have checked where the setting is used but is there no code using hires while it should not ? (setting ignored, missing code to ignore the const  )
Placebo    just tell it to my system which I have to reboot 2 or 3 times per day using Dooble.... (frozen, hung)

* Firefox is outdated for many sites *

Regards

Note: I have no skills into this code. Doing several searches on internet, I found some qt developers using webengine having resolved hires timing issues using process cycles instead (is it possible ?)   

Even if qt6 on OS/2 *is* using hires timing (I have NFI) I cannot understand how that webengine flag is making any difference. The link I posted is where qtwebengine interprets flags - it cannot interpret the flag on OS/2, so the flag is ignored.

I am also *not* a programmer. I can barely write a hello world in C without googling it. How about you inject a deliberate typo into the flag you;'re using with hires and see if you still see the same 'improvements' - that might confirm Dave's thoughts on timing.

Will give it a try and post back

May it be possible this constant isn't well taken into some parts of the codes ?

I searched the entire code base, that link I posted is the only place where webengine flags are interpreted, and the timer variable is only interpreted on Windows.

I have no idea how this could possibly make any difference, other than the placebo effect.

Cheers,

Hello Remy,

Ok, read it.
I don't understand why when adding this switch, Dooble is more stable while it should have no effect but it has here !
(adding this switch, I'm able to use Dooble without setting priorities. Without it, I need to add priorities settings)

Could it be that this SET statement impacts other apps on your system which in turn have an impact on the QT stuff?

I have a few apps here that would fit the bill:
1) FF - where I no longer have this set, while in earlier versions I did
2) PUMONITOR - by default I'm using the hires timer to gether runtime statistics
3) DISKIO - the version I am currently working on is using this approach

Now of course if you are running/testing the QT apps w/o anything else on your OS/2 box currently running, that would at least limit that spillover effect that other apps might have.

Hi Dariusz,

I did a try removing auto started application and just left as is from a new install.
Same Dooble result here!

One time, I could see a blocked named pipe established by webengine (Theseus) just before system hung (reboot required)
Many troubles about sound (sound no more working, sound issued into a short loop etc... uniaudio installed)

It looks like disabling hires timer makes QTwebengine more stable.
Could it be possible a problem exist into C++ about hires timer ?  (under windows, they had to increase precision)

https://github.com/psmedley/qt6-webengine-os2/blob/main/src/3rdparty/chromium/base/base_switches.cc#L120

This switch is doing nothing on OS/2.

Thanks.

I wonder why passing an NSPR4 argument has an effect on Dooble? It is an OS/2 thing and as far as I remember only the environment variable has an effect.
Dooble --help 2> dooble.hlp gives this for the list of dooble specific arguments,

Code: [Select]

Dooble
 --attach
 --disable-javascript
 --executable-current-url PROGRAM
 --full-screen
 --help
 --listen
 --load-url URL
 --normal-screen
 --private
 --reload-periodically 15, 30, 45, 60
 --test-aes
 --test-aes-performance
 --test-threefish
 --test-threefish-performance

Chome has a huge list of arguments, which I assume the Qtwebengine also has, see https://peter.sh/experiments/chromium-command-line-switches/
They can usually passed in the environment set QTWEBENGINE_FLAGS=

What do you think about:
https://doc.qt.io/qt-6/qdesktopservices.html

Hi Dave !

The test you can try:
Start Dooble, open this os2world web page and then clic on above FTP link ...
Always start my default browser firefox.

That is weird. Here it opened a new window in SeaMonkey, my default browser, which was running. Tried the ftp://ftp.os2voice.org/dooble/ link too, opened a new window in SM with the request for password. Very strange bug or I guess feature especially with ftp kind of broken in the web engine.
Tried with the simplebrowser, as expected the Qt5 one failed, the Qt6 one worked the same as dooble

I found some information about FTP no more supported under Chrome since 88... like current firefox windows 64 no more supporting it.
Is it the case for Dooble ? If yes and at least, I expect a popup menu to select external ftp compatible program to use and route the link to it 

Regards

That's strange and doesn't happen here. Looking at the documentation, we have,

Code: [Select]

Supported Schemes
Dooble supports the FILE, FTP, GOPHER, HTTP(S), and JAR schemes.
So Dooble should open the FTP//: links.

I tried again:
Firefox is closed

Start Dooble (QT6)
put link ftp://ftp.pmoylan.org/Major/ + enter
The page goes blank !
Waiting a few more seconds, firefox is starting showing files from ftp://ftp.pmoylan.org/Major/ !
It looks like Dooble is opening ftp link but not into its browser nor into a new tab and cmd is resolved as system browser to open

Have your default ArcaOS set to firefox and firefox not started
then, start Dooble and give a try to the link

Doing a test starting Dooble with the link provides a different result (blank page and nothing more):
Dooble ftp://ftp.pmoylan.org/Major/

Yes, something seems broken with the ftp protocol. Here with the Qt6 dooble, I got a blank page, Qt5 dooble closed.
Tried ftp://ftp.os2voice.org/dooble/ too, Qt6 dooble kept reverting to about:blank, Qt5 dooble gave me an error about the site not being reached.
Tried ftp://dry@ftp.os2voice.org/dooble/ and got a popup to enter user and password, after entering the info, dooble-qt5 vanished., dooble-qt6 gave a blank page.
These failures also don't get saved in the history, just the ftp://ftp.os2voice.org/dooble/ with the not found error got saved.
I'd guess the ftp problem is in the Qtwebengine.
OTOH, gopher works, eg gopher://magical.fish/

Strange !

I installed QT 6.2.11 using latest end december QT6 Dooble
I tried the link again under Dooble.
A blank page.... waiting more, my default system browser (firefox) opens with the link from Dooble displaying all files !
Oh! Dooble opening system default browser in this case...

Info: Since adding qt webengine parameter  " --disable-highres-timer" into my starting process, I could remove my priority setting and have a working dooble with QT6.2.10  (faster youtube start and more stable during video change)
Current parameter I'm using:
"--disable-gpu --ignore-certificate-errors --ignore-ssl-errors --log-level=1 --disable-highres-timer"
And into config.sys
set NSPR_OS2_NO_HIRES_TIMER=1

An other issue where rendering is very very slow !
I compared firefox and Dobble (QT5 or QT6, similar result)
Using following link, page flip is very slow !
