Since this are a part of nonBazaar core packages,
this would be nice to work properly.
I tested this on w7x64 with latest upp-included-clang(16299) and msvc17
producing 32bit debug executable with reference example - GLDrawDemo.
But for this - i used msvc17 since debugger gave me a little more info.
I have also tested this with producing 64bit code,
but it was even worse(only blank white screen).

Anyhow, i attached screenshots where bug happens,
if one is a little bit more familiar with underlying code,
one could probably resolve this quite easily.

Commented code also mostly all produces such bugs.
~~~~~

Bazaar(uppHub) thing:
i suggest - don't throw away Bazaar archive - it has a lot of usefull code.
I didn't for example found Serial package or non-bazaar FontSel(dialog)
in uppHub(maybe i overlooked something), which are mostly just copy/paste
packages - since all works out of the box.

For Serial bazaar package i just added this, to adjust a few things,
for linux, i am not sure if this is needed or how it's done.
  void SetWriteTimeout(dword ms){
    COMMTIMEOUTS ct;memset(&ct,0,sizeof(ct));
    ct.WriteTotalTimeoutConstant=ms;SetCommTimeouts(fd,&ct);
  }
  void SetTimeouts(dword msRead,dword msWrite){
    COMMTIMEOUTS ct;memset(&ct,0,sizeof(ct));
    ct.ReadIntervalTimeout=ct.ReadTotalTimeoutMultiplier=MAXDWORD;
    ct.ReadTotalTimeoutConstant=msRead;
    /*ct.WriteTotalTimeoutMultiplier=MAXDWORD;*/
    ct.WriteTotalTimeoutConstant=msWrite; SetCommTimeouts(fd,&ct);
  }

Hello,

Thank you for your feedback! In context of UppHub this is the step forward in comparison to bazzar and we shouldn't back to it anymore. The reason for that is that many packages are outdated and there are lack of maintainer. I know that currently we do not have Serial package on UppHub, but why do not create one? If you are interested you can create UppHub repository with Serial package from bazaar. This package will be maintain by you.

To create UppHub package, just create git repository and full-fill them accordingly. You could follow the repository structure of AutoScroller. If everything will be ready just let us know that you have created Serial package, so we could add it to UppHub registry.

---------------------------------------
BTW, You put two topics into one thread. Please raise separate topic for GLDraw issue. For me it works correctly on Windows10. Are you compiling GLDrawDemo on virtual machine or something, there might be a problem with a drivers. Also, you should migrate to more modern system. Windows7 hit end of the life, so there is no grantee that everything will be working as expected. Could you try on Windows10. Windows11 or GNU/Linux?

EDIT: OK, after testing we have a fatal error at the begging of the program when targeting 32 bit operating system on Windows. On 64 bit everything works correctly. If you compile with USEMALLOCK it should works fine.

Why do not you start UppHub package for serial?

Seriously, the problem with bazaar was that while it contained a lot of great code, 90% of it was unmaintained.

I think that at least Serial and Sound(wrapped PortAudio soundsystem+plugin/wav)
should go into plugin or core packages, since they are fundamentals.
Serial code won't change in the future, and probably neither PortAudio,
so maintaining code is not an issue, copy/paste packages to core would be fine.

Of course, i have made copies of bazaar archive, just in case you'll be stubborn Smile.
Personally, i prefer main upp-download to be as small as possible, without bazaar and git,
but bazaar and/or github as an option. Upphub may be a plus for some situations
and of course - it could be a handy option and probably "flaten out" newVers diferences
between bazaar and upp bugs.
If one is eager for upphub thing, then one could probably create converter
from bazaar to upphub, and mark/review packages as fullyFuncional or unmaintained, etc.
If this is started: from my experience - Serial and Sound are fully functional.
SoundExample code is also there and functional albeit for blocking mode. Streamed mode
is from my experience fully functional also.

The same goes for FontSel that was proposed soooo many times but not integrated into core(uppsrc/CtrlLib),
all is there only this is lacking for dialogs(colorchooser,FileSel,etc) to be complete.
FontSel code was written by someone else - but i think i changed it a bit some time ago,
anyhow - it's attached(if integrated - only check/correct FontSel.h and FSel.cpp header paths - 2linesOfCode).


What about GLDraw and GLCtrl - core of this topic?
This are also fundamentals..
It's a simple correction for one that knowns how underlying code should work.

Hello Luoganda,

Serial is niche. It shouldn't be part of the Core package and any developer that is currently engage in Upp framework development do not have much experience with that. So putting it there doesn't make sens to me.

However, the different story is with UppHub. It fits there perfectly. It is great addition that expands capabilities of whole Upp framework.

As you see there is no maitaner and the person who wants to move that package there. Could you help with this? Do you want to be a person deserved to our community? If yes, please create GitHub repository in accordance to instruction in this documentation page and let us know when it will be ready. We will handle the package publishing process for ourselves.

Luoganda, I believe in you that you publish your first package on UppHub! Good luck!

Tested (with RX580), works. Unfortunately this can be GPU/GPU driver releated; I will try again once I have got Nvidia sometimes this or next month.

Meanwhile, why do not you try to investigate? Have tried to e.g. get backtrace for starters?

I am not fundamentally opposed to this.

Hello Mirek,

Did you tested with 32 bit clang on Windows (not 64 bit)? I reproduce it with default CLANG build method (not CLANGx64). The error is only with 32 bit, 64 works without crash. It reproduces for both Nvidia and AMD GPU, so I am sure that it is not driver related. I attached screenshot with crash.

Here is backtrace:

As I wrote previously, using malloc instead of our allocator solves the problem in this case.

Does not crash for me, but backtrace is helpful. You have not posted the screenshot, but it appears like "Writes to freed blocks detected" issue?

Obviously, this is is not detected with USEMALLOC for simple reason that normal allocator does not have any such detected.

Anyway, probably the problem is somewhere about image cache recycling/freeing (related to rendering the text). Can you try with

		w.DrawLine(80, 90, 400, 0, PEN_DASHDOT);
	//	w.DrawImage(200, 10, CtrlImg::reporticon());
	//	w.DrawImage(280, 10, CtrlImg::reporticon(), Red());
		const char *text = "This text is centered";
		Size tsz = GetTextSize(text, Arial(25).Bold());
	//	w.DrawText((sz.cx - tsz.cx) / 2, (sz.cy - tsz.cy) / 2, text, Arial(27).Bold(), SBlue);
		w.Clipoff(200, 50, 95, 100);
	//	w.DrawText(0, 80, "CLIPPED", Roman(25));
		w.End();
		
	//	for(int angle = 0; angle < 360; angle += 30)
	//		w.DrawText(sz.cx - sz.cx / 3, sz.cy - sz.cy / 3, angle * 10, "x   Text with angle " + AsString(angle));


just to test if we are onto something?

Next thing to try is to comment GLDraw/Texture.cpp:43 SysImageRealized

Hello Mirek,

Commenting SysImageRealized doesn't help. Also, commenting w.DrawImage(), too. What helped is commenting loop with angle:
		//for(int angle = 0; angle < 360; angle += 30)
		//	w.DrawText(sz.cx - sz.cx / 3, sz.cy - sz.cy / 3, angle * 10, "x   Text with angle " + AsString(angle));
		


So, following code works fine on 32-bit windows:
	virtual void GLPaint() {
		Size sz = GetSize();
	
		GLDraw w;
		
		w.Init(sz);

		w.DrawRect(0, 0, sz.cx, sz.cy, SWhite);
		w.DrawRect(10, 10, 30, 30, SRed);
		w.DrawLine(45, 45, 80, 120, 4, Blue);
		w.DrawLine(80, 90, 400, 0, PEN_DASHDOT);
		
		w.DrawImage(200, 10, CtrlImg::reporticon());
		w.DrawImage(280, 10, CtrlImg::reporticon(), Red());
		
		const char *text = "This text is centered";
		Size tsz = GetTextSize(text, Arial(25).Bold());
		
		w.DrawText((sz.cx - tsz.cx) / 2, (sz.cy - tsz.cy) / 2, text, Arial(27).Bold(), SBlue);
		w.Clipoff(200, 50, 95, 100);
		w.DrawText(0, 80, "CLIPPED", Roman(25));
		
		//for(int angle = 0; angle < 360; angle += 30)
		//	w.DrawText(sz.cx - sz.cx / 3, sz.cy - sz.cy / 3, angle * 10, "x   Text with angle " + AsString(angle));
		
		w.End();
	}

------------------
OK, after digging more AsString(angle) is causing crash. It works good with following line of code:
w.DrawText(sz.cx - sz.cx / 3, sz.cy - sz.cy / 3, angle * 10, "x   Text with angle " /*+ AsString(angle)*/);

Replacing AsString with IntStr cause the same error. I think the problem must be with utoa32 (Format.cpp) function and it's memory management on 32 bit architecture.

Well, accidentally, AsString in this case does not allocate any memory.... Smile

What is more likely that glyphs for digits are maybe causing the problem. Maybe you can replace AsString with "123" ?

Hello Mirek,

You are right inserting numbers in the string cause crash. Below line crashes:
w.DrawText(sz.cx - sz.cx / 3, sz.cy - sz.cy / 3, angle * 10, "x   Text with angle 123");


So, it is not a problem with number to string conversion. Thanks for explanation about memory allocation Wink

Keep experimenting. What about "xxx" instead of "123" ? (These are glyphs that already should be cached).

The card is a little older
intel Q965/Q963 Express Chipset Family.
So yes, Mirek - it might be this.
Although i think that with gl2.0 should also work fine for basic line etc drawing,
if there are limits what glVer upp needs - then it might be this.
On w7x64 i have also directx11.

On windows - there are only drivers till 2.0 for opengl(rev 8.15.10.1930),
on linux - i think there are for 2.1 too.

Checked,
minimum OpenGL version on any platform is fully supported v2.1.

Meaning:
with older graphics card mentioned in previous post,
in this case - GLDraw/GLCtrl works ok on linux with latest drivers but not on win7(drivers not supporting full 2.1 capabilities).
