Tools for tracing OpenGL, Direct3D, and other graphics APIs

About apitrace

apitrace consists of a set of tools to:

• trace OpenGL, Direct3D, and DirectDraw APIs calls to a file;

• replay OpenGL and Direct3D calls from a file;

• inspect OpenGL and Direct3D state at any call while retracing;

• visualize and edit trace files.

See the apitrace homepage for more details.

Status

TL;DR: Apitrace is still being maintained, but the maintainer has very little time to work on it, so patches/issues/requests are addressed if/as time permits.

Long version here

Obtaining apitrace

To obtain apitrace either download the latest binaries for your platform if available, or follow these instructions to build and install it yourself.

On 64bits Linux and Windows platforms you'll need apitrace binaries that match the architecture (32bits or 64bits) of the application being traced.

Usage

Detailed usage instructions are available here.

apitrace's Issues

segfault in replayStateFound

revision: 38c932b

I get segfaults at random when retracing to do state lookup in qapitrace, but the only reliable way I found to reproduce a crash is like this:

1. Run qapitrace under gdb
2. start a 'Lookup State' operation
3. Ctrl+C to interrupt it, then resume the program.

It triggers a null deref like this:

^C
Program received signal SIGINT, Interrupt.

save trace subset to render a particular object

I would like the option to save the part of trace required to render a particular mesh with the textures and shaders as applied to it.

Sometimes a glitch could be demonstrated with a much smaller trace that way.

Show StencilBuffer properly.

If StencilBuffer consist of more than 3 different bits, qapitrace show solid black as StencilBuffer On Surface tab.

ApiTrace does not show all textures

ApiTrace with OpenGL on Windows:

The QApiTrace application does not show GL_TEXTURE_RECTANGLE textures when inspecting the state.

Also, I would find it helpful if the Surfaces tab showed more information about the textures - texture id, mipmap level (or even group mipmap levels for a single texture), data type (float/byte/...).

glretrace crashes

I have a trace that causes glretrace to crash

crash on glDrawArrays with count 0

OS: Windows 7 x64

My program is crashing while using the OpenGL wrapper .dll on the following call:

glDrawArrays(GL_TRIANGLES,0,render_list.size());

render_list.size() is 0 at this point. It is probably poor form on my part, but the docs for glDrawArrays don't mention a count of 0 as being bad. Skipping this call when render_list is empty makes the problem disappear.

Crash when opening a (possibly corrupted) trace file

Hello,

in the process of debugging a complete machine crash with radeon and "big" vertex arrays, I asked the reporter to provide a glapitrace.

I cannot open the trace on my machine as it crashes apitrace with a segfault. I suspect the file is corrupted, but I assume the application should not be getting a SIGSEGV either way.

The file can be found at http://www.qfpost.com/download.do?get=7df4b0244d5ce3628b84758d4cfa1acd

Thanks

Exeption error on second trace file load within qapitrace

Behaviour: exception error occurs on loading a second trace file from the same instance of qapitrace.

To reproduce:

1. Load a trace file (a.trace)
2. Load another trace file (b.trace)
3. Experience exception error.

Cause is
trace_parser.cpp
Ln:55 assert(!file);
File object is not deleted before loading another trace file.

Callstack:

Building the GUI on windows

I get lots of compiler errors in vertexdatainterpreter.cpp (resulting from WINGDIAPI and APIENTRY being undefined inside gl.h).

The file includes GL/gl.h without including windows.h, which seems to be necessary.

In GLee.h (an extension loading library), the include block looks as follows:

#ifdef WIN32
    #ifndef WIN32_LEAN_AND_MEAN
    #define WIN32_LEAN_AND_MEAN
    #endif
    #include <windows.h>
    #include <GL/gl.h>
#elif defined(__APPLE__) || defined(__APPLE_CC__)
    #define GL_GLEXT_LEGACY
    #include <OpenGL/gl.h>
#else // GLX
    #define __glext_h_  /* prevent glext.h from being included  */
    #define __glxext_h_ /* prevent glxext.h from being included */
    #define GLX_GLXEXT_PROTOTYPES
    #include <GL/gl.h>
    #include <GL/glx.h>
#endif

In glext.h, there is the following block:

#if defined(_WIN32) && !defined(APIENTRY) && !defined(__CYGWIN__) && !defined(__SCITECH_SNAP__)
#define WIN32_LEAN_AND_MEAN 1
#include <windows.h>

Obviously, when decompressing the tarball in a directory of choice and launching cmake and make from here (with the same parameters as above) the build succeeds, so the culprit lies somewhere between the source CMakeList.txt and the Mandriva build system...
And yes, I could simply adapt and hardcode in my spec file the steps lisrted in the INSTALL.markdown file, but I would prefer to find a way to use all the nice macros the Mandriva build system provides and still have a successful build of apitrace.
So, being a monkey-packager rather than a true and competent developer, I have to ask for help:
how can I have a successful build of apitrace without totally defeating my distro build system?

TIA.

Crash when using OpenGL from different threads

It is not allowed to make OpenGL calls from different threads. I just happen to have a (windows) application which did it anyway and worked. Here's what happened when I used ApiTrace:

Main Application: create an OpenGL context from thread 1
Main Application: call glEnable from thread 1. Works as intended.
Plugin DLL: call glEnable from thread 2. Crash in wgltrace.cpp, inside glEnable: calling __glEnable, a NULL pointer.

So ApiTrace helped me to find the bug. However, after calling a NULL pointer, you loose the call stack (at least in the Visual Studio), so you don't know where the bug is.
If it is not too expensive, it might be therefore a good idea to check the function pointer (or thread id) before calling it.

Timeline view.

debian packaging

I wrote a debian package for apitrace.

Anyone interested can update the debian/changelog file with current package version and build a package for their Debian or Ubuntu system.

If github allows me to upload the tarball, that is.

Unigine Heaven benchmark crashes

On Linux the Unigine Heaven benchmark crashes at startup when one is trying to trace it. The benchmark is available from:
http://unigine.com/download/
start it with:
./x64_1024x768_windowed_tess_normal.sh (./x86_1024x768_windowed_tess_normal.sh if running on 32bit system)

a way to truncate / reduce / edit traces

Right now i have a trace that's 76 MB, but because it's producing a gpu hang the bulk of it is the final frame caught in an infinite loop of querying state that never changes -- 13,530,363 calls in Frame 560 versus 113,795 in the first 559 frames. The calls in the infinite loop are just dead weight, so it'd be nice to have a way to prune them-- expanding the final frame to view all the calls in it inflates memory usage from 20 MB to 4.3 GB, and only the first thousand or so are interesting.

No output when retracing file if glViewport not called

I've tried using apitrace 2.0 with my application (OpenGL, Windows) but, while tracing works fine, retracing seems to be broken. When I retrace I don't get a window at all, and if I retrace in qapitrace.exe to inspect buffers, I get garbage on framebuffers and a tiny squished down version of the actual texture on textures I've rendered to with a FBO.

I've uploaded a trace file here: http://www.mediafire.com/?jrgjv6cu0gd4p2v
The source code for the application is here: https://github.com/yuriks/cga-t2/tree/eeedf8813ce3804ae8f6dedec2eb8ace28d5a848

gDEBugger also seemed to have problems reading the buffers, so it may be something specific to my application that's causing issues.

Visualize meshes in draw commands.

It would be nice to view the vertex buffers used for rendering. Ideally both pre and post vertex, geometry and tessellation shaders. Windows PIX allows for something along those lines, docs are at

envp PWD=

i would fork but I'd have nothing else to contribute. Coming undergraduate Operating Systems class, you look in the envp* dictionary. I forget how to get things out of dictionaries in C but the envp* dictionary is a parameter of your main function so, for example
int main(int argc,char *argv[],char *envp[])
printf("The environment is as follows:\n");
int a = 0;
while (envp[a] != NULL)
printf("\t%s\n", envp[a++]);
return 0;
the *envp pointer is a dictionary, so it should print out the entire environmental dictionary. where did u think bash was getting it?

Better call details view

Right now the call details view is rather ugly and not very useful. It should show more info, at least the error if any at the current call, plus all the docs from the resources (both extensions and man pages).

On-demand loading of trace files

Currently the GUI freezes if we're loading a larger trace file. A well gzip'ed 200mb trace file can easily take +4gb in ram so we're just running out of memory. We need to incrementally load the data. Most likely through memory mapping the entire trace file and being able to seek in it. The gui needs to know:

• the number of frames int the trace file
• the number of calls in each frame

and it has to be able to:

• get calls for every random frame,

So something like the following would be great for the gui:

class ApiTrace
{
public:
    ApiTrace(const std::string &filename);
    int numberOfFrames() const;
    int numberOfCallsInFrame(int frameIdx) const;
    // loaded on demand or fetched from a fixed size (e.g. within 100mb) cache
    ApiTraceFrame *frame(int frameIdx);
};

// loaded frame
class ApiTraceFrame 
{
public:
    int numberOfCalls() const;
    const ApiTraceCall *calls() const;
};

Qapitrace: Surface Viewer: Window extent calculation / scroll bars

The Surface Viewer calculates the optimal window size to display the surface, but the horizontal and vertical border offset is not included in the calculation for the intial window size.
This results in all Surface Viewer windows having horizontal and vertical scrollbars.

At first I thought it could be due to my dual portrait enviroment, I tested on a 'normal' configuration as well and observed the same behavior.

File: mainwindow.cpp
Function: void MainWindow::showSelectedSurface()
Line: 622
viewer->resize(qMin(int(0.75 * screenRect.width()), img.width()) + 40,
qMin(int(0.75 * screenRect.height()), img.height()) + 40);

changing to these values yields the intended effect.

viewer->resize(qMin(int(0.85 * screenRect.width()), img.width()) + 60,
qMin(int(0.85 * screenRect.height()), img.height()) + 60);

Batched state lookups

Right now, as far as I can see, you can only lookup state for one frame/call at a time. It would be nice and very time saving to be able to ask for several calls to be looked up at once, and, even better, for the retracing to pause and sit idle once it reaches your frame, so that future lookups on calls after that one resume from where you paused, instead of starting the whole retracing over again.

Assertion in Parser::parse_value()

After reading zrushin's blog I did a short and quick test. All seemed to work fine but a replay (and qapitrace & others) are failing with an assertion in Parser::parse_value(): "error: unknown type -1".
Removing the assert and returning 0 solves the problem - the replay works fine until the end.

Fix retracing of OpenArena

There's a number of artifacts in retracing OpenArena.

apitrace shows the wrong buffer in snapshots

When I do snapshots in retrace they show small black squares.

When I do snapshots with -sb I get errors about invalid buffer (obviously) and every other snapshot shows the traced app (upside down).

Crash when editing a trace

After editing the number of vertices to a glDrawArrays call, apitrace saves the edited trace, then when I do a state lookup I see the replay going on, and once the replay has ended, apitrace crashes with a segfault :

Process error = 1
err = "glretrace: /home/arthur/src/apitrace/trace_model.cpp:80: virtual long long int Trace::Value::toSInt() const: Assertion `0' failed.
"
out = ""
Segmentation fault (core dumped)

The core dump contains nothing useful, I'll see if I can rebuild with debug symbols.

Help appreciated.

apitrace crashes while tracing

I can't give you the trace because

1. github does not allow attaching files

2. the trace contains copyrighted material from the application in question which is disallowed on github

3. the trace is large (a few megabytes compressed)

gltrace loops infinitely when TRACE_FILE cannot be opened

When the environment variable TRACE_FILE is set to a read-only/nonexistent location or an invalid filename like "~/traces/bluh.trace" (without the shell expanding the ~), gltrace keeps repeatedly trying to open it until the program exits:

apitrace: tracing to ~/traces/bluh.trace
apitrace: tracing to ~/traces/bluh.trace
apitrace: tracing to ~/traces/bluh.trace
apitrace: tracing to ~/traces/bluh.trace

It should probably just abort() with a descriptive error that the file couldn't be opened instead of retrying for the whole run of the program and tracing nothing.

Markers in GL command stream

gDEBugger had special extensions that could be used to output a string marker in the GL command stream. This allowed you to break execution at given points (for example, when a given object was going to be drawn). It was useful to be able to debug specific areas of the program.

It was rudimentary however. I would think it would be pretty simple to do something even more powerful, for example, use a string to name these markers and then be able to break execution only when a marker with a given name was reached, or output start/end markers and record trace only between these markers.

All this is so that apitrace is easier to use in a more targeted way, and with large programs where, in its current state, it is very slow and outputs very large trace files.

Support multiple GL contexts

Currently we can only correctly retrace if only one GL context is used.

Unsupported symbols

Does apitrace support platform specific OpenGL calls? I'm getting this error on Snow Leopard testing out Firefox:

DYLD_LIBRARY_PATH=/path/to/apitrace/wrappers /Applications/Firefox.app/Contents/MacOS/firefox

dyld: Symbol not found: _glFlushRenderAPPLE

Trace/BPT trap

Display all textures? Support GL_KHR_debug object labels?

Hello,

I realize this may be slightly out of scope for apitrace, but I find myself often wondering what is the texture ID for a given texture I have in mind.

Would it be technically possible for apitrace to dump all existing textures, and display them? This is somewhat part of the state after all.

Thanks

Trace editing

Implement simple trace editing in the GUI. Initially, not addition of removal of calls but just editing arguments to individual calls. It should be possible to edit arguments, replay the new trace and save it.

Typo in CMakeLists

./gui/CMakeLists.txt, line 48:

It should be QJSON_INCLUDE_DIR and not QJSON_INCLUDE_DIRS (as set in FindQJSON.cmake)

Also, I had to manually add PC_QJSON_LIBRARY_DIRS and PC_QJSON_INCLUDE_DIRS entries in my CMake configuration, otherwise it could not find qjson (which I installed by building INSTALL from the CMake-generated qjson project).

Resolving symbols for dynamically loaded GL libs

There's a wonky case of applications which don't link to GL, linking to a library which doesn't link to GL but dlopens another library which links to GL. In this case our dlsym seems to return NULL for gl/glx symbols and the glxtrace.so exits with:
error: unavailable function "glXGetProcAddressARB"
testing:
starting any Qt 4.7+ application with argument "-graphicssystem opengl" e.g.:
qapitrace -graphicsssytem opengl
assistant -graphicssystem opengl
and so on (qtopengl library needs to be installed).

Show all shaders in a program?

Hello, I imagine you will get many new users like me now that gDEBugger has been bought by AMD and turned into a Visual Studio 2010-only plugin... I've tried out apitrace and have a few requests to make. I currently have no available development time or I would implement these myself - perhaps if no one gets to them soon it will still be me, but it's still useful to discuss these here and record them.

We have multiple shader objects attached to our program objects most of the time, and it seems qapitrace does not display them all (it seems to display the last one, which is not necessarily the one that has the main() ). It would be useful to be able to see them all. I guess this is a GUI issue only, as obviously all shaders are in the trace file because the scene looks fine when replaying the trace.

Thanks in advance.

apitrace crashes when tracing wine

Example session, with steam (this is just starting steam, even before "loading" windows appears, and not starting any game):

$ wine Steam.exe
[8 wine warning/fixmes removed]
signal_handler: sig = 11
apitrace: flushing trace due to an exception
Erreur de segmentation

I remember it used to work several months ago, so I started bisecting apitrace, and found this commit to cause the breakage:
3d9a70c
I added signal numbers 11 (SIGSEGV), 10 (SIGUSR1) and 3 (SIGQUIT) to current code "ignore" list, and I could dump a trace again.

I'm still puzzled as to what the right fix would be... I'm surprised a library[ wrapper] registers signal handlers: shouldn't it just leave them alone ?

edit: 10 is SIGUSR1, much less scary than SIGBUS...

Reading multisampled buffers in GL

Lots of apps is using multisampled surfaces (Qt "-graphicssytem opengl" are easy to test) and one can't use glReadPixels on buffers with multisampling enabled. Right now we're just getting garbage on those buffers. We'll need to use something akin to glBlitFramebuffer to blit to another non-multisampled buffer and read that.

Create an edit menu

Create an edit menu with search, go to, go to beginning of the frame and go to end of frame.

Window resizes

When capturing frozenbyte's shadowgrounds and replaying it with glretrace, the GL window is resized a few times. There was no resize while capturing it.

Retrace failing on Windows, built with Visual C++ Express 2008

Hi,
I built APITrace with Visual C++ Express 2008 on Win 7 32-bit. None of the traces I recorded would playback correctly as glretrace reported that all the GL functions were unknown.

I found that in retrace_call(), "name" was not pointing at the GL function name. I fixed this issue with the following:

bool retrace::retrace_call(Trace::Call &call) {
{
char *name;
name = new char [call.name().size()+1];
strcpy(name,call.name().c_str());

...

delete[] name;
}

Standalone GLES tracer

Hello,

I see that you just started working on a GLES2 branch, which is very interesting. I'm working on a platform where only EGL/GLES2 are available, with no X11 or OpenGL support.

I've tried hacking the makefile to only build a tracer for GLES/GLES2 and EGL, however it seems the code depends on OpenGL being available. Do you have plans to support this kind of build, and if not, can you please give me some advice on how this would be doable ? Does the tracer need to have any knowledge of the EGL platform backend to create pixmaps, images or windows ?

Thank you very much.

Start / stop trace

It would be useful to be able to start / stop the trace to be able to make the trace more targeted. I could see two ways to do this:

• Expose some kind of API in the wrapper DLL, which the app could call to start / stop tracing. This would be very flexible, because the app could start / stop tracing at known points, or it could expose a button in its own GUI, or whatever.
• Make an application, similar to gDEBugger, that would run the app we want to trace, and which would start / stop tracing when the user clicks a button. This would be very user-friendly.

The second idea could even be made part of the wrapper DLL I guess - when the wrapper sees the first OpenGL call, it spawns a small Qt GUI that lets you control the tracing. As long as tracing is not started, the wrapper just forwards calls, and when the user presses a "play" button on that GUI, then the wrapper starts saving all commands to the trace file, until the user presses a "stop" button on the GUI or the application quits.

This would help users trace only at known performance-critical times, and it would make trace files smaller.
