Function names are not resolved if profilee exits too soon (original: The column Function does not contain function names)

[sebhtml]

Hello,

Versions

• Microsoft Windows 10 Pro
• Microsoft Visual Studio Professional 2015 Version 14.0.25431.01 Update 3
• MicroProfiler 1.7.624.0

Steps to reproduce

1. File -> New -> Project... -> Win32 Console Application
2. Right-click on project, click "Enabled profiling"
3. Press CTRL + F5

Expected result

A table with function names is shown, including function names.

Actual result

A table with function names is shown, but function names are all empty strings.

Hi

This seems to be a known issue with dbghelp.dll that cannot read 'fast' PDBs.
Please try to set "Project Settings / Linker / Generate Debug Info" to /DEBUG or /DEBUG:FULL rather then /DEBUG:FASTLINK. See #52

Thank you,
Artem

Hi,

In Visual Studio 2015, I am using /DEBUG.

I tried /DEBUG:FULL :

Thank you.

[tyoma]

Got it.
Another thing that comes to mind - since your application is very small (I presume it's just a basic template ConsoleApplication) the symbols may not be loaded during the application lifetime (the loading is done in the profilee process asyncrhonously). Can you please add waiting for user input before exiting it?

thanks,
Artem

Hi tyoma,

You were right.

With the following Win32 Console Application, it does work.

// ConsoleApplication3.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
#include <sstream>

int main()
{
	std::ostringstream s;
	for (size_t i = 0; i < 100000; ++i)
	{
		s << i << std::endl;
	}

	std::cout << s.str() << std::endl;

    return 0;
}

It means that the problem is not a problem with MicroProfiler or with Visual Studio, but rather with the options used when building the proprietary software I am working on at my job.

You can thus close the issue.

I thank you for your time and expertise.

Cool! In fact, it still seems to be kind of an issue - applications running too fast will leave UI without function names - I'll better keep this issue open for a time being...

Hi tyoma,

With what you said in mind, I found a workaround to be able to have symbols in the profiling table when using MicroProfiler.

I simply added a sleep before my program exits.

+#include <chrono>

+       std::this_thread::sleep_for (std::chrono::seconds(60));

@tyoma Nice new edited title BTW.

TIL my programs are profilees.

[tyoma]

Isn't it the same to employer/employee?

[sebhtml]

Yes, it is.

English is not my mother tongue.

I use caller/callee. But I had never saw profiler/profilee.

[tyoma]

neither it's mine ))

@sebhtml, @r-pankevicius, guys, please check the new release (2.0.637) for the fix of this.
Thank you!

@tyoma
Pulled latest, compiled and ran playground vs standalone (Debug, Win32).
No issues with function names now, and the little magic happened: main was called 1 time, not 0.

Looks good for me, thank you.
I don't have plans to install release version, though.

My version is:

commit 32f6981c643b93997752d414f631fd6684772b28 (tag: v2.0.638.0, origin/master, origin/HEAD)

thanks @r-pankevicius!

@tyoma Some time ago I saw the issue: if time is more that 1s it is reported as 0.
Not sure if I was fooled by "1 call was reported as 0" then or such issue existed.

Anyway, now I see times longer than 1 second OK.

@tyoma I will try it out at work in Visual Studio 2019 to test the water. Thanks !

[tyoma]

thanks, @sebhtml !

Hi Artem,

I installed MicroProfiler Version 2.0.637.0 in Visual Studio Professional 2019 Version 16.7.5 and it works well. Thanks.

Cool, thanks @sebhtml !!!
