Irrlicht 1.8. Application not closing and memory leak...

[christianclavet]

Hi, This could be my application, but before I was using 1.7.3 and the application did not do this.

When I try to close my application, (debug mode using IRRlicht dll debug version). The main window (containing the opengl context) close, but the console window does not and I have to manually close, it. Then MSVC tell me there is a memory leak warning:

From what I read, it seem to come from: COpenGLDriver.cpp. But I'm not really sure. The current application is running irrlicht 1.8.0 in OpenGL on Windows 7.0.

Another thing to note, I'm opening a NULL driver first to get the configuration files, open the openGL with the configuration and close the null device. (Worked perfectly under Irrlicht 1.7.3)

What I find strange is that the "dumping" refer to Irrlicht source files not the files I'm using in my project.

Detected memory leaks!

Anyone can help? I'm doing exit(0) to close the app, after the device->closeDevice() and device->drop(), but still the console window is there and the app is still there, until I close the console window.

[Nadro]

Please use this combination:

Code: Select all

device->closeDevice();
device->run();
device->drop();

It will solve Your problem.

[christianclavet]

Thanks Nadro. Tried it and it still doesnt close the console.

Here the full close on closing:

Code: Select all

void App::shutdown()
{
    // Stuff to do when the device is closed.
    SoundManager::getInstance()->stopEngine();
    cleanWorkspace();
    DynamicObjectsManager::getInstance()->clean(true);
    device->closeDevice();
    device->run();
    device->drop();
    exit(0);
}

Getting the "desktop" resolution this way at initialization (part of "loadConfig"):

if (resizable && fullScreen)
{
IrrlichtDevice * tempdevice = createDevice(EDT_NULL,dimension2d<u32>(640,480), 16, false, false, false, 0);
screensize = tempdevice->getVideoModeList()->getDesktopResolution();
tempdevice->closeDevice();
tempdevice->drop();
}

Here fully opening the device:

Code: Select all

void App::setupDevice(IrrlichtDevice* IRRdevice)
{
 
    loadConfig();
 
    if (!IRRdevice)
    {
        device = createDevice(EDT_OPENGL, screensize, 32, fullScreen, false, false, 0);
        this->device->setResizable(resizable);
        device->setWindowCaption(L"IrrRPG Builder - Alpha release 0.21 (october 2012)");
    } else
        device = IRRdevice;
 
    driver = device->getVideoDriver();
    smgr = device->getSceneManager();
    guienv = device->getGUIEnvironment();
 
    device->setEventReceiver(EventReceiver::getInstance());
    timer = device->getTimer()->getRealTime();
    timer2 = device->getTimer()->getRealTime();
    timer3 = device->getTimer()->getRealTime();
    LANGManager::getInstance()->setDefaultLanguage(language);
    quickUpdate();
 
}

As another note, I executed the application OUTside MSVC, the console windows seem to stay there but close by itself (surely doing a memory leak).

[Nadro]

Hmmm... Please put a "run" method for a closing tempdevice too:

Code: Select all

tempdevice->closeDevice();
tempdevice->run();
tempdevice->drop();

Maybe it will help.

[CuteAlien]

Which VS are you using? And do you have those problems as well when running the Irrlicht examples? Please also take a look at the log-messages in case there are any warnings or so.

[christianclavet]

VS 2008.
I don't see any warning. All of the example seem to be good. As I've said, previously, the current code I had worked and was terminating correctly under 1.7.3. Once I had messages like that that pointed me to irrKLang, replaced it for the new version and the leak was gone. (using Irrklang 1.4 in the app). All the messages are pointing to theses files:
CNullDriver.cpp
COpenGLDriver.cpp
CImage.cpp

Humm, looking more, it seem that it could perhaps affect RdR PostFX framework that was in (using untouched shaders), I have also theses "items" and I don't think theses belong to Irrlicht:

WorldMatrix
ViewMatrix
texture0
texture1
texture2
ColorR
ColorG
ColorB
Contrast
BufferWidth
NoiseStrength
LuminanceThresho
...

These seem to report to shaders, could it be that the PostFX Framework, make Irrlicht leak because it set up the shader improperly? (as of 1.8.0 there are changes there)
I'll try to disable it to see if it change something and report back, thanks!

Still see the problem in the demo, when set in full screen, when closing the "demo", my windows screen is set at 800x600. Tried in windowed mode and it's ok. So for now, using full screen mode will change the desktop size.

I´m seeing a massive 12 MB memory leak when using the opengl driver.

Using D3D driver there is no leak.

Even if I just create the Irr device and load nothing at all, not even a texture or cube, after correctly deleting irr device 12 MB never returns!

Its been like this for a while now, at least since 1.7.2.

VS 2008.
I don't see any warnings. All of the examples seem to be good. As I've said, the current code I had worked and was terminating correctly under 1.7.3. Once I did had leak messages like that that pointed me to irrKLang, replaced it for the new version (1.4) and the leak was gone under 1.7.3 (Not seen any leak message, and all thread were reporting a exit code 0.

Robmar, what were you using to see leaks in OpenGL with 1.7.2? That just happened once I switched the library to 1.8.. Irrlicht 1.7.2 and Irrlicht 1.7.3 were not reporting leaks for me.

Now in 1.8.0, all the messages are pointing to theses files:
CNullDriver.cpp
COpenGLDriver.cpp
CImage.cpp

Humm, looking more, it seem that it could perhaps affect RdR PostFX framework that was in (using untouched shaders), I have also theses "items" and I don't think theses belong to Irrlicht:

WorldMatrix
ViewMatrix
texture0
texture1
texture2
ColorR
ColorG
ColorB
Contrast
BufferWidth
NoiseStrength
LuminanceThresho
...

These seem to report to shaders, could it be that the PostFX Framework, make Irrlicht leak because it set up the shader improperly? (as of 1.8.0 there are changes there)

[EDIT]Reporting back:

Disabling it seem to have changed a lot in the output of the leak (the framework is not initialized now), other irrlicht files are being reported:

I see some data coming out from other shaders (water/terrain shader), but they were fixed and are displaying properly now. Are there new methods to dispose of them?

Here how the shader is applied:

Code: Select all

  //Create a Custom GLSL Material (Water shader)
   static s32 materialOcean=smgr->getVideoDriver()->getGPUProgrammingServices()->addHighLevelShaderMaterialFromFiles(
        "../media/shaders/ocean.vert", "vertexMain", video::EVST_VS_1_1,
        "../media/shaders/ocean.frag", "pixelMain", video::EPST_PS_1_4,
        ShaderCallBack::getInstance(), video::EMT_TRANSPARENT_ALPHA_CHANNEL);
 
    static ITexture* oceanLayer0 = smgr->getVideoDriver()->getTexture("../media/waveNM.png");
    static ITexture* oceanLayer1 = smgr->getVideoDriver()->getTexture("../media/sky.jpg");
 
    //Assign GLSL Shader
    ocean->setMaterialType((E_MATERIAL_TYPE)materialOcean); 
    
    //Assign Textures
    ocean->setMaterialTexture(0,oceanLayer0);
    ocean->setMaterialTexture(1,oceanLayer1); 
 
    ocean->setMaterialFlag(EMF_FOG_ENABLE,true);

Here are some of the output that I get on MSVC when I close the app (I have to force close it, by closing manually the console window).
I see tons of warning about "irrMap.h" ( and COctreeTriangleSelector.cpp, CGUIEnvironment.cpp, etc.) now. This is only a partial output of what I have because the forum thread cannot take all the text.

Is using shader under GL cause a memory leak?! (or bad setup that worked on 1.7.3 will cause that)

[EDIT 2]
irrMAP it reported to a specific line and here is the line: (line 192)

Code: Select all

        Node* newNode = new Node(keyNew,v);

.\COctreeTriangleSelector.cpp(78) : {715403} client block at 0x07D2BF90, subtype 0, 80 bytes long.
Here is the line 78:

        node->Child[ch] = new SOctreeNode();

.\CSceneManager.cpp(1830) : {714860} client block at 0x0724AD40, subtype 0, 92 bytes long.
Here is line 1830:

Code: Select all

    return new COctreeTriangleSelector(mesh, node, minimalPolysPerNode);

.\CImage.cpp(57) : {712185} client block at 0x07A20040, subtype 0, 1048576 bytes long.
Here is line 57:

Code: Select all

        Data = new u8[Size.Height * Pitch];

I could go on and on like that, it's looking that when I try to close the device, the objects are not being disposed properly. What could cause that?
Something still in rendering and used while it's being closed?

Detected memory leaks!

Well I sort of had a clue something was wrong after cycling my applications and Windows 7 ran out of memory!

I had thought that Windows 7 was for sure protected, and reserved enough memory to continue operation, like Unix, but seems not!

So I then monitored my app using TaskManager, which gives resource allocated for each running app.

This works nicely as it gives one total figure for all memory allocations used by any process/program.

So I can easily see the jump when Irr device is created, 20 MB if D3D is used, or 65 MB if OpenGL.

And I can see that whereas the D3D released the memory, under OpenGL 12MB gets lost.

Hi, I rebuilded the Irrlicht DLL in release mode, and tried to run my application and close it again. Stragely, MSVC doesnt report any memory leak now and all threads report exit = 0.
How can the debug build of the library could do that in MSVC?

[hybrid]

Well, memory debugging is only available in debug modes for sure. So nothing will be reported in the release version. You need other tools for that. But also make sure that your app is not closed via Alt-F4, but by clicking some close button. Otherwise the MSVC mem checker will report lost ressources which are cleaned up by the system handler. This is not seen by MSVC, so many false reports are generated.

[robmar]

So what about the massive memory leaks reported by Windows resource monitor, and Task Manager app list, which shows the same 12 MB loss each time irr device is created and deleted but only when the opengl driver is selected, and this loss happens without even adding a single node!

Does that just happen in Windows? Has anyone checked yet, as it only takes about 3 line of code...

[CuteAlien]

Sorry, wasn't coding today. Please be a little bit more patient, we work on the engine in our spare-time and additional to answering forum posts and hunting more bug-reports, we also occasionally spend one of our free days on others stuff. Especially after spending the last weekend and every evening this week on a release... (also I'm working on another release in my day job as well right now).

Don't worry - by now there is probably no one left reading this forum who hasn't seen the 12 MB memory leak mentioned, we won't forget it ;-) It's not exactly that much of a show-stopper anyway - usually the opengl device isn't something you open and close all the time and there are no leaks reported on normal examples, so it doesn't seem to happen on the usual program quit.

[robmar]

Okay, point taken! Oops, sorry!!

Initially I tried creating the irr device and reusing it, as I need to load scenes that can be quite complex, but after droping/removing all the content, the state of the engine was usually a bit "weird", such that shaders that previously loaded didn´t work quite right anymore.

So I delete and re-create the engine before loading new scenes, so its a bit of a headache that opengl loses memory.

Some of my scenes use hlsl, others glsl, so deleting and recreating the device was the only solution I could find.

Hybrid has told me to create a sample to show the leak, which I will do tomorrow.

Not sure where I should post the zip...
