GammaRay is a tool to poke around in a Qt-application and also to manipulate the application to some extent.

GammaRay is a software introspection tool for Qt applications developed by KDAB. Leveraging the QObject introspection mechanism it allows you to observe and manipulate your application at runtime. This works both locally on your workstation and remotely on an embedded target.

Augmenting your instruction-level debugger, GammaRay allows you to work on a much higher level, with the same concepts as the frameworks you use. This is especially useful for the more complex Qt frameworks such as model/view, state machines or scene graphs.

Among other things GammaRay can:

• Browse the QObject tree with live updates.
• View and edit object properties.
• View and invoke slots of a QObject, and monitor its signals.
• List all QObject inbound and outbound signal/slot connections.
• Provide a layout information overlay for QWidget and QtQuick2 applications.
• Inspect all QPainter operations used to draw a specific widget.
• Browse the QtQuick2 item tree and scenegraph.
• Inspect shaders and geometry data of QtQuick2 items.
• Plot object lifetime and emitted signals.
• Browse the QAbstractProxyModel hierarchy and inspect intermediate results in a proxy model chain.
• Visual live inspection of QStateMachines.
• Browse the item tree of any QGraphicsView scene.
• Show a live preview of QGraphicsView items, including showing their coordinate system, transformation origin, rotate/zoom/pan, etc.
• Intercept translations and change them at runtime.
• Inspect all building blocks of a QStyle.
• Show all QTimers and their statistics (number of wakeups, wakeup time, ...)
• Browse all QTextDocuments, along with the ability to edit them and view their internal structures.
• Act as a complete java script debugger, attachable to any QScriptEngine (including the usually not accessible one used by QtQuick1 internally).
• Perform HTML/CSS/DOM/JS introspection/editing/profiling on any QWebPage, thanks to QWebInspector.
• Browse the QResource tree and its content.
• Show all registered meta types.
• Show all installed fonts.
• Show all available codecs.

Linking CXX shared library Issue on Windows

I'm trying to compile this on windows and I get the error

Statemachine visualizer doesn't color active state when runtime attaching

When runtime attaching to a running application, the graph doesn't show the current state in red, even though the state treeview shows the state checked.
See attached screenshot.

Assert failed caused by timertop plugin

I'm getting an assert caused by the timer top plugin:

This seems to be caused by the plugin setting a dynamic property, from the main loop, on a QTimer that was created in a thread.

Failing to attach to Qt application on Mac OS X 10.6.8

Trying to attach to my Qt 4.8.1 based application I get this error using latest gammaray from git:

Ensure gammaray_probe can be found in the build tree

Ubuntu 10.04 / g++ (Ubuntu 4.4.3-4ubuntu5.1) 4.4.3

In config-gammaray.h.cmake, currently GAMMARAY_BUILD_DIR is specified as

#define GAMMARAY_BUILD_DIR "${CMAKE_BINARY_DIR}"

This prevent the gammayray_probe library from being loaded properly because it is currently built into the core sub directory and the method findProbe is not searching into that sub directory but directly in GAMMARAY_BUILD_DIR instead.

Multiple versions coinstallability

AFAIK, gammaray installs some binaries/headers to the bin/include/lib directories with fixed names. Therefore, it is impossible right now to install both Qt4 and Qt5 versions of gammaray at the same time (in the same prefix). I use gammaray to debug Qt theme in both Qt4 and Qt5 applications (which works great!!!) and it will be really useful to have both of them.

One possible solution is to allow adding custom suffixes with a compile time argument, so that the executable can be named gammaray-qt{4,5}, the header files can be installed to /usr/include/qt{4,5}/gammaray, and the libraries can be named libgammaray_common_qt{4,5}.so etc. This way, it will not break any existing build (the suffixes can default to empty) and it allows distributions to easily custimize the names to fit their policy with the compile time argument.

I can try to submit a pull request if this solution is accpetable.

GammaRay cause application under test to crash

We have a big desktop QML application. I was trying to debug some visual issues with GammaRay, but when our application connects to a server and start receiving data, it crashes (according to GammaRay) at a point where it doesn't crash in QtCreator/gdb. There doesn't appear to be any relevant information in the console, and GammaRay doesn't tell anything useful either.

GammaRay is started on the console with the application as an argument

GammaRay compiled from latest master as of today, with Qt 5.3.0 on 64 bit Kubuntu 14.04

cannot inspect QStateMachine

The statemachine view is not selectable on the sitepanel.

Enviroment: Qt5.3-mvsc12 compiled with graphviz 2.38 and cgraph library. Also KDSME ist installed and found by cmake. Gammaray is compiled as debug build. So is the test application.

It seems that the plugin is compiled. At last gammaray_statemachineviewer_plugin.dll is in the plugins directory and it is listet in the Plugins-Info-Panel.

I created a statemachine like this:

this->m_stateMachine = new QStateMachine(this);
QState *s1 = new QState();
QState *s2 = new QState();
QState *s3 = new QState();
QState *s4 = new QState();
QFinalState *final = new QFinalState();

s1->addTransition(this,SIGNAL(signal_a()),s4);
s4->addTransition(this,SIGNAL(signal_b()),s2);
s2->addTransition(this,SIGNAL(signal_c()),s4);
s4->addTransition(this,SIGNAL(signal_d()),s3);
s3->addTransition(this,SIGNAL(f()),s1);
s1->addTransition(this,SIGNAL(final()),final);

this->m_stateMachine->addState(s1);
this->m_stateMachine->addState(s4);
this->m_stateMachine->addState(s2);
this->m_stateMachine->addState(s3);
this->m_stateMachine->addState(final);

this->m_stateMachine->setInitialState(s1);
this->m_stateMachine->start();

also the QStateMachine Object is not visible in the Objects tree of GammaRay although the parent object (this) is.

Setting the statemachine as property will produce an qWarning:

 Q_PROPERTY(QStateMachine* State MEMBER m_stateMachine)

 qWarning: Cannot serialize QVariant of type QStateMachine*

Crash during inspection GraphicsScene.

Sequence to reproduce:

• launch "qt4/examples/graphicsview/portedcanvas/portedcanvas" from gammaray launcher.
• select "graphics scenes" tab and select any graphics item to view its properties.
• on inspected application: File->Erase Canvas (Ctrl+E).

As result: Gammaray with inspected application crashes.
It looks like that there is no mechanism that handles GraphicsItem deletion on inspected scene.

https://buildd.debian.org/status/fetch.php?pkg=gammaray&arch=mipsel&ver=1.2.2-1&stamp=1356200317

To be sure that the overwriting for qt_startup_hook will work,
test connectiontest-preload with readelf --relocs --wide checks if sybmbol
qt_startup_hook is marked as relocatable with JUMP_SLOT relocation, which
means that symbol will be resolved by dynamic linker and called at run
time through the plt.

The problem for Mips is that it has, besides the plt, another method of
calling functions from .so files, and this method doesn't need JUMP_SLOT
relocations (in fact, it doesn't need any relocations). This method uses .got
entries and lazy binding stubs. For example, if we call printf function, the
typical code is (gp register here points at the .got section):

lw t9, offset(gp) // load in t9 function pointer from the address gp + offset
jalr t9 // call the function in t9

Initially, the memory at gp + offset will contain the address of the lazy
binding stub for printf. Lazy binding stubs look like:

lw t9, 0(gp)
move t7,ra
li t8,7
jalr t9

First instruction loads in t9 the address of the function _dl_runtime_resolve
from the predefined place in .got (it is located in first .got entry).
_dl_runtime_resolve is dynamic linker's function which resolves calls to
functions from .so files (printf in this case). Second and third instructions
load registers t7 and t8 with arguments that _dl_runtime_resolve needs. The key
argument here is 7 - it is dynamic symbol table index of printf, so that dynamic
linker knows which function to search for. Last instruction calls
_dl_runtime_resolve. After _dl_runtime_resolve finds printf in some .so file, it
will overwrite the .got entry for printf with found printf address, so that next
calls to printf will not go through lazy binding stub, but directly call printf.

All this doesn't need any relocations (below will be explained why). There is a
method how it can be determined whether a call to function will go through .got
and lazy binding stub.

First, Mips ABI specifies that .got is divided in two parts - local and global.
Dynamic linker only resolves symbols from the global part of the .got (that is,
only symbols from global part of the .got have lazy binding stubs. Entries from
the local part of the .got are filled with final values during static linking).
Mips ABI also specifies that the order of symbols in global part of the .got
must match the order of symbols in dynamic symbol table. In the .dynamic section
(obtained with "readelf -d" command), there is a Mips-specific dynamic tag
DT_MIPS_GOTSYM which gives the dynamic symbol index of the first symbol that has
entry in global part of the .got. So, the symbol with dynamic symbol index of
DT_MIPS_GOTSYM will be placed in the first entry in the global part of the .got.
The symbol with dynamic symbol index of DT_MIPS_GOTSYM+1 will be placed in the
second entry in the global part of the .got and so on.

For the previous example, lets suppose that DT_MIPS_GOTSYM is 6. Since the
dynamic symbol index of printf is 7, printf will be placed in the global part of
the .got (in the second entry of the global part of the got), and call to printf
will go through .got and lazy binding stub, and will be resolved by dynamic
linker.

From the previous explanation, it should be clear why calling functions through
.got on Mips doesn't need any relocations. Dynamic linker knows which .got entry
corresponds to which symbol, based on matching between .got and dynamic symbol
table. For the plt, on the other hand, there is no matching between the .got.plt
entry and the dynamic symbol table - function addresses in .got.plt can come in
arbitrary order. This is why every .got.plt entry needs R_MIPS_JUMP_SLOT
relocation - so that dynamic linker knows which symbol corresponds to this entry.
(Note that on Mips, pointers to functions which are accessed though plt are
placed in separate .got.plt section, not in .got like on Intel for example.)

To summarize, the method to determine whether the call to function will go
through .got and lazy binding stub is:

• find the value of dynamic symbol index of the function with the command
  "readelf --dyn-syms"
• find the value of dynamic tag MIPS_GOTSYM with the command "readelf -d"
• if (dyn_sym_index >= MIPS_GOTSYM) then the function has entry in the global
  part of the .got, and the call will go through lazy binding stub and be
  resolved by dynamic linker.

For the case that function is accessed through plt, the existing method that
searches for relocations should also be tried, with the exception that on Mips
the relocation to search for is R_MIPS_JUMP_SLOT.

Dejan Latinović

Please create an AppData file for GammaRay

Please consider writing and installing an AppData file with the application description and some screenshots, else GammaRay looks really bad in the GNOME Software Center. See http://people.freedesktop.org/~hughsient/appdata/ for details; thanks!

Compilation error on linux

Missing unistd.h include in attach/processfiltermodel.cpp and injector/interactiveprocess.cpp leads to compilation error.

Resource view not updated after calling QResource::registerResource

With QResource::registerResource(), one can register resources dynamically. Gammaray doesn't refresh its resource view though.
Same for QResource::unregisterResource().

ObjectVisualizer does not work with VTK 6.0

Plugin linking fails, because VTK 6.0 does not have libQVTK.so. The library is called libvtkGUISupportQt.so instead.

Even when the linking error is fixed, GammaRay will crash when you try to open the Object Visualizer tab:

Hi. I get these compilation errors on Windows 7 x64.
I had to do this because by default it was compiling in debug mode...
cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=release ..
Then I executed nmake and the compilation went up to 81% and this is where I got these errors. What library am I missing here? Thanks for your help.

Can't compile under Windows when using GraphViz 2.36

This is probably the same or very similar to Issue 70, but I've been having this problem on Windows even using the latest codebase with the fix for Issue 70 in there.

I'm on Windows using the VS2010 compiler, Qt 5.2.1, and GraphViz 2.36, and I get the following errors when nmake reaches the gammaray_statemachineviewer_ui_plugin dependencies:

MacOSX Install Location (and Bundle)

The Install.txt claims that on MacOSX GammaRay should be installed as /Applications/GammaRay.app but when I build the current git master this does not happen and I'm not seeing anything in the CMakeLists.txt to configure this. I can run /usr/local/bin/gammaray fine but since this isn't a proper MacOSX bundle it's missing things such as the application icon and menubar entries.

Doesn't highlight preview when clicking on sublayouts

When going to widgets-> then clicking on nested layouts, the highlight remains on the top layout.

#include <QApplication>
#include <QDebug>
#include <QWidget>
#include <QColorDialog>

int main(int a, char**b)
{
    QApplication app(a, b);
    QColorDialog dialog;
    dialog.exec();
    return app.exec();
}

gammaray targeted process is grayed out

I was able to compile gammaray however launching gammaray with the command line throws this error.
No probe found for ABI qt4.8-MSVC-release-i686

Also using the gammaray launcher the process list is grayed out

segfault while trying to attach to running process

Trying to attach to a running process (New empty GUI template project of QtCreator) using the dialog of GammaRay (GammaRay is running with sudo as root).
The process is found, here is the gammaray output when stopping:
Remarks:

• my "untrusted .gdbinit" adds qt source navigation to QtCreator
• /var/tmp/kdecache-christian owner error is due to running as root

Unable to build with Visual Studio 10

d:\gammaray\workspace\plugins\quickinspector\quickinspector.h(63): error C2216: 'override' kann nicht zusammen mit 'inline' verwendet werden

This seems to be a bug in Visual Studio 10 (http://connect.microsoft.com/VisualStudio/feedback/details/684900).

Separate core from GUI

Hi. It would be nice to see a basic functionality in a standalone library, which could be used in other applications.
Also it would help to make the design of the program more clear.

GammaRay crashes on 10.8

I can't get latest GammaRay to attach to a process without crashing.

The relevant gist is here: https://gist.github.com/kubark42/9be0804b2d667f9646c6

Compile error with GraphViz 2.36.0

I get an error when I try to compile GammaRay (same with 2.0.0, 2.0 and master).
This seems to be related with GraphViz. I have version 2.36.0 installed.
With GraphViz 2.34.0, it works.

segfault on dialog "cancel" after calling QSpinBox.setValue() from GammaRay

Seen with 1.1.0, built on a Debian testing upgraded today before building gammaray.

The app to look at though gammaray is https://alioth.debian.org/projects/omaha/, at commit
http://anonscm.debian.org/gitweb/?p=omaha/omaha.git;a=commit;h=30ef5e94c98ccd18ccd2eae9dd5cbd2d420d053b

To reproduce:

• launch ./scripts/omaha --toolkit Qt4
• attach gammaray
• select "Checkers", and menu Main/Play

From gammaray:

• browse widgets until finding the "Board Size" QSpinBox in the QDialog
• call setValue(10) on it

Hit cancel in the dialog:
=> omaha terminates with "Segmentation fault"

Gammaray cannot attach if python is run under gdb, and a corefile does not get properly decoded by gdb. Any hint to get more precise info ?

Command line options to disable vtk and graphviz support

Could you please add command line options to disable vtk and/or graphviz support? On a x86_64 environment without 32bit version of those libraries installed, the cmake module sometimes find the the 64bit version and then fail in the linking stage.

I'm not 100% sure if it is impossible to workaround it without the option but having one seems useful anyway.

GammaRay 1.3.2 on Fedora 17

I followed the installation steps:

• mkdir build
• cd build
• cmake ..
• make
• sudo make install

if I launch the application by the command gammaray occours the following error:
"gammaray: error while loading shared libraries: libgammaray_ui.so: cannot open shared object file: No such file or directory"

The application runs if I launch it from the folder:
/myDir/Gammaray-master/build/bin using the command ./gammaray

In any case when I attach any Qt process by GammaRay crash both!

Doesn't find Graphviz on archlinux

Please test the FindGraphviz.cmake with a recent version of graphviz.

I have graphviz 2.34.0 on my system

One bug is probably here:
find_path(GRAPHVIZ_INCLUDE_DIR graphviz/graph.h PATH ${_GRAPHVIZ_INCLUDE_DIR})

I don't have a graph.h file, and neither a libgraph.so

No way to copy the backtrace out of the messagehandler dialog

Example: http://wstaw.org/m/2012/11/19/plasma-desktopCf1097.png

There's no way to copy the backtrace from that dialog.

A good solution would be to add a "Copy backtrace" button in the dialog which copies it to the clipboard. (Just like DrKonqi does it).

Support for QtQuick(Control) applications?

In Qt5, a QQuickItem is not a QWidget and therefore cannot be visualized (in the same way with QWidget) in gammaray. Is it possible to add support for this?

Signal view bar turns black on focus loss

The bar displaying the signals turns black if the application looses focus.

GammaRay sidebar greyed out

I built the recent head of GammaRay for Qt5.2.1 on x64, Windows. When attaching to or launching a compatible app (release or debug), inprocess or out of process local, I always get this:

Note the left sidebar is completely greyed out, and the actions menu is empty, and nothing is available. Am I doing something wrong or is this a bug?

Unable to configure plugins and libexec installation destination

Passing -DLIBEXEC_INSTALL_DIR=/usr/libexec/gammaray to CMake has no impact and gammaray-launcher and gammaray-client are always installed to /usr/lib64/gammaray/libexec. Although this is a good default, it would still be nice if packagers could choose the destination (e.g. /usr/libexec/gammaray, as recommended by Fedora packaging guidelines).

Passing -DPLUGIN_INSTALL_DIR=/usr/lib64/qt4/plugins to CMake is ignored by all plugins (they install to /usr/lib64/gammaray/version/qt-build/), except for gammaray_kjobtracker, which installs to /usr/lib64/plugins/version/qt-build/.

I tried making the variables configurable by users (see the patch below), which worked for plugins, but has broken lookup of the libexec utilities:

$ gammaray                                                                      
"gammaray-launcher" not found in the expected location(s): 
"/usr/bin/..//bin/gammaray-launcher, /usr/bin/..///usr/libexec/gammaray-launcher" 
continuing anyway, hoping for it to be in PATH. 

libexec is usually not in PATH, so it does not work :)

LIB_INSTALL_DIR set to a Relative Path

Hi, I noticed that you set the LIB_INSTALL_DIR variable in line 123 of GammaRay-1.3.0/CMakeList.txt to a relative path. This triggers some security warnings in Gentoo when installing the package. Is this intended or can it be changed to /usr/lib${LIBSUFFIX}?

State machine graph broken for states with duplicate object name

I've got state machine in which multiple states can have the same name, for example there are 3 states with the object name "directory", each with a different parent.
The tree view on the left shows that correctly.
However, in the graph view on the right, there is only one "directory" state, and the hierarchy is messed up because of that.
