Here is the second try to have stacktrace support in Pulseview complete. Changes since v1: * HACK crashes now when you press "Run" in pv, so you can view logs before * added check if 'backtrace' is supported on the system * depending on that, the backtrace tracer or the simple tracer is used * no hardcoded libs anymore, all replaced by variables * enforcing the debug build was removed. Also, no warning yet when you enable stacktrace and have no debug symbols
For symbols outside pv, you still need to disable ASLR with $ sudo sysctl -w kernel.randomize_va_space=0 or using 'setarch ... -R ...' If you do that, the backtrace tracer gives nice output: pv: Stack trace file is "/tmp/pv_stacktrace.dmp" pv: "Stack trace of previous crash:" pv: --------------------------------------------------------- pv: 0# signal_handler(int) at /home/ninja/Tools/sigrok/pulseview/main.cpp:88 1# 0x00007FFFF63A38E0 in /lib/x86_64-linux-gnu/libc.so.6 2# raise at ../sysdeps/unix/sysv/linux/raise.c:51 3# signal_handler(int) at /home/ninja/Tools/sigrok/pulseview/main.cpp:90 4# 0x00007FFFF63A38E0 in /lib/x86_64-linux-gnu/libc.so.6 5# pv::MainWindow::on_run_stop_clicked() at /home/ninja/Tools/sigrok/pulseview/pv/mainwindow.cpp:713 6# pv::MainWindow::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) at /home/ninja/Tools/sigrok/pulseview/pulseview_autogen/PLNN4COFE5/moc_mainwindow.cpp:156 7# QMetaObject::activate(QObject*, int, int, void**) at kernel/qobject.cpp:3788 8# QAbstractButton::clicked(bool) at .moc/moc_qabstractbutton.cpp:309 9# QAbstractButtonPrivate::emitClicked() at widgets/qabstractbutton.cpp:416 10# QAbstractButtonPrivate::click() at widgets/qabstractbutton.cpp:395 11# QAbstractButton::mouseReleaseEvent(QMouseEvent*) at widgets/qabstractbutton.cpp:1012 12# QToolButton::mouseReleaseEvent(QMouseEvent*) at widgets/qtoolbutton.cpp:623 13# QWidget::event(QEvent*) at kernel/qwidget.cpp:9355 14# QToolButton::event(QEvent*) at widgets/qtoolbutton.cpp:986 15# QApplicationPrivate::notify_helper(QObject*, QEvent*) at kernel/qapplication.cpp:3728 16# QApplication::notify(QObject*, QEvent*) at kernel/qapplication.cpp:3203 17# Application::notify(QObject*, QEvent*) at /home/ninja/Tools/sigrok/pulseview/pv/application.cpp:318 18# QCoreApplication::notifyInternal2(QObject*, QEvent*) at kernel/qcoreapplication.cpp:1047 19# QApplicationPrivate::sendMouseEvent(QWidget*, QMouseEvent*, QWidget*, QWidget*, QWidget**, QPointer&, bool) at kernel/qapplication.cpp:2697 20# QWidgetWindow::handleMouseEvent(QMouseEvent*) at ../../include/QtCore/../../src/corelib/kernel/qcoreevent.h:304 21# QWidgetWindow::event(QEvent*) at kernel/qwidgetwindow.cpp:224 22# QApplicationPrivate::notify_helper(QObject*, QEvent*) at kernel/qapplication.cpp:3728 23# QApplication::notify(QObject*, QEvent*) at kernel/qapplication.cpp:3486 24# Application::notify(QObject*, QEvent*) at /home/ninja/Tools/sigrok/pulseview/pv/application.cpp:318 25# QCoreApplication::notifyInternal2(QObject*, QEvent*) at kernel/qcoreapplication.cpp:1047 26# QGuiApplicationPrivate::processMouseEvent(QWindowSystemInterfacePrivate::MouseEvent*) at kernel/qguiapplication.cpp:2083 27# QGuiApplicationPrivate::processWindowSystemEvent(QWindowSystemInterfacePrivate::WindowSystemEvent*) at kernel/qguiapplication.cpp:1818 28# QWindowSystemInterface::sendWindowSystemEvents(QFlags) at kernel/qwindowsysteminterface.cpp:1032 29# QPAEventDispatcherGlib::processEvents(QFlags) at ./src/platformsupport/eventdispatchers/qeventdispatcher_glib.cpp:71 30# QEventLoop::exec(QFlags) at kernel/qeventloop.cpp:213 31# QCoreApplication::exec() at kernel/qcoreapplication.cpp:1335 32# main at /home/ninja/Tools/sigrok/pulseview/main.cpp:335 33# __libc_start_main at ../csu/libc-start.c:342 34# 0x00000000004AABDA in ./pulseview pv: --------------------------------------------------------- Simple tracer still works, too. Again no testing on non-Linux platforms. Thanks to Soeren, Gerhard, and Uwe for support! Looking forward to comments.
