Hardware / Re: OS/2 Video Performance
« on: October 24, 2021, 04:18:26 am »
Not sure if stuff like FF for example uses DIVE or not? But at least here that's probably the most demanding applicatin (given that it's all about on-going screen updates) and from my perspective it seems like a higher 'PM Graphics Marks' value impacts this the most.

It depends, DIVE is supposed to be disabled if using Panorama and enabled if using SNAP.  I have a vague memory of things getting backwards at some point, need to look. Also perhaps Panorama has improved its handling of the shadow buffer enough that DIVE would be a good choice.
The setting for DIVE should be "Full Hardware Acceleration enabled" or similar.

DIVE is not switched off with Panorama. Its something provided by MMOS/2.

As Paul said, the Mozilla apps turn off DIVE when they detect Panorama or in safe mode. from SeaMonkey's stdout,
Code: [Select]
DIVE is disabled - Panorama's shadow-buffer is enabled
the code from nsWindow.cpp,
Code: [Select]
  // Don't use DIVE if the Panorama video driver is in use
  // unless its shadow buffer is turned off.
  HMODULE hmod;
  if (!DosQueryModuleHandle("PANOGREX", &hmod)) {
    char      str[8];
    if (PrfQueryProfileString(HINI_USERPROFILE, "PANORAMA", "VBEShadowBuffer",
                              0, str, sizeof(str)) && !strcmp(str, "0")) {
      sUseDive = TRUE;
      printf("Video driver is Panorama - shadow-buffer is disabled\n");
    }
    else
      printf("DIVE is disabled - Panorama's shadow-buffer is enabled\n");

    return;
  }

  sUseDive = TRUE;

I think it was Rich who made that decision based on DIVE having crappy performance with the Panorama shadow buffer. If the shadow buffer is turned off in the Screen object, Firefox will use DIVE.
Other video drivers use DIVE but hide the pointer when writing to the framebuffer.
As said, it is also controlled by the video acceleration preference.

My own build Thinkpad 25/2:

PM Graphic Marks: 58.294
Dive Marks: 7336.388

That's sure slow drawing lines. Have you ever compared with running SNAP? Here SNAP is slightly faster and the individual tests are somewhat different in results. Luckily this Intel BIOS has wide screen resolutions in it.

Programming / Re: Function MACRO or #DEFINE?

While Lars's description of a macro actually doing something sounds right, I've consistently seen things like "#define __OS2__ 1" referred to as a macro.

You probably could update the certificate then, at least it supports a new enough TLS, probably 1.2

Web applications / Re: firefox - newtab thumbnail images are empty, why?
« on: October 20, 2021, 06:27:03 pm »
Could it be a page that needs lots of JavaScript to display images?
You can always go to about:support to review any preference changes you have made.

At least, "firefox-31.8.0.en-us.os2.beta_5-wpi.wpi" still works.

Good to know. Have you tried updating the letsencrypt certificate or did you just add an exception for here?
I'm inclined to keep all working browsers on Hobbes.

Hi Martin, missed this.
For the name of the directory, either of your ideas seems fine.
As for which versions. I guess if you want to trim older ones, I'd keep at least the 38ESR and the 45ESR various versions as there still seems to be people who prefer SM 2.35 at least and they still work. Older versions are getting useless as they don't support new enough encryption.

Setup & Installation / Re: YUM default platform setting
« on: October 19, 2021, 04:26:24 pm »
Hi Martin, you will have to turn off the hyperthreading on the command line of ACPI, not the simplest thing to do as yo have to figure out which cores are real and which are fake and use a bitmask to only use the real ones. First try adding /CPUMASK=1 to the PSD line in config.sys to test with only one CPU. If OO now works on the problem system, that will tell you it is a hyperthreading problem.
The PSD documentation is under x:\sys\docs\ACPI as psd_en.pdf. See the ACPI command line section. You might have to open an issue to get help.
As for the i686 vs Pentium 4 thing, Bitwise seems to be guiding us to Pentium 4 systems to support the new browser. As Neil said, more to come.

Applications / Re: Seamonkey Data Leakage
« on: October 15, 2021, 09:20:56 pm »
Our old Mozilla (SM, FF and TB) is full of security holes I'm sure, as well as design decisions that may allow leakage. Mozilla did go to sandboxing each tab in its own process as that seemed the only universal fix.
For now, a Master Password might help, untested. And under Preferences-->Privacy & Security-->Private Data you can set it up to clear a lot of that stuff when closing the browser.
There's also the right mouse buttons context menu when right clicking on a link "Open Link in Private Window" which I use quite often.
Edit: I'll add that at least SeaMonkey does give these options unlike Firefox.

Setup & Installation / Re: YUM update qt5-qtbase-common fails
« on: October 13, 2021, 04:12:11 pm »
Try to install the os2-base first by updating it to version 0.0.1-3.oc00.
Then you retry the update.
I'm not sure if it works.
Saludos

After installing os2-base, you need to install dbus-libs, then the update should work.

Posting from Otter, one drawback is no add-ons, or rather just user JS scripts. Can turn off JavaScript globally but I'd miss No-Script though having an up to date hosts file would help.
Ok. I see it does have content blocking along with a way to import various lists.

You're right, it is not really supported but I installed it on Mint, a Ubuntu based distribution with this method, seems to work fine and seems pretty good. This is actually the procedure for Ubuntu
Code: [Select]
sudo add-apt-repository ppa:otter-browser/release
sudo apt-get update
sudo apt-get install otter-browser

That almost sounds like a build issue. Might be some missing libs though, perhaps the readme gives a hint?
Under Ubuntu, you can use apt in similar ways to yum. "sudo apt update" to update package list, "sudo apt upgrade" to install updates, "sudo apt install foo" to install. Should also be graphical frontends available too. I haven't used Ubuntu in a while but all Debian based Linuxes work much the same. Trick is to figure out what packages Otter needs. I guess ours is going to use NSS for secure browsing so try installing NSS and NSPR4 perhaps.
