From 9c6e3590da6c49d055d452b08de0e51b0b77f1c4 Mon Sep 17 00:00:00 2001 From: Gunnar Sletta Date: Mon, 9 Nov 2009 07:58:56 +0100 Subject: Fixed up qttracereplay and trace graphicsystem a bit. - Added "qttrace" to binary file, making it possible to do a sanity verification of the input file in qttracereplay - Sanity check input binary file, both for existance and for content in qttracereplay - Console app on windows and mac - Added helpful output for -h and --help command line options Reviewed-by: Samuel --- .../trace/qgraphicssystem_trace.cpp | 1 + tools/qttracereplay/main.cpp | 38 ++++++++++++++++------ tools/qttracereplay/qttracereplay.pro | 2 ++ 3 files changed, 31 insertions(+), 10 deletions(-) diff --git a/src/plugins/graphicssystems/trace/qgraphicssystem_trace.cpp b/src/plugins/graphicssystems/trace/qgraphicssystem_trace.cpp index 8756ecb..fb6f5ea 100644 --- a/src/plugins/graphicssystems/trace/qgraphicssystem_trace.cpp +++ b/src/plugins/graphicssystems/trace/qgraphicssystem_trace.cpp @@ -82,6 +82,7 @@ QTraceWindowSurface::~QTraceWindowSurface() QFile outputFile(QString(QLatin1String("qtgraphics-%0.trace")).arg(winId)); if (outputFile.open(QIODevice::WriteOnly)) { QDataStream out(&outputFile); + out.writeBytes("qttrace", 7); out << *buffer << updates; } delete buffer; diff --git a/tools/qttracereplay/main.cpp b/tools/qttracereplay/main.cpp index 1d21a21..7261082 100644 --- a/tools/qttracereplay/main.cpp +++ b/tools/qttracereplay/main.cpp @@ -56,7 +56,7 @@ public: public slots: void updateRect(); -private: +public: QList updates; QPaintBuffer buffer; @@ -70,7 +70,8 @@ private: void ReplayWidget::updateRect() { - update(updates.at(currentFrame)); + if (!updates.isEmpty()) + update(updates.at(currentFrame)); } void ReplayWidget::paintEvent(QPaintEvent *) @@ -138,12 +139,25 @@ ReplayWidget::ReplayWidget(const QString &filename_) QFile file(filename); QRect bounds; - if (file.open(QIODevice::ReadOnly)) { - QDataStream in(&file); - in >> buffer >> updates; + if (!file.open(QIODevice::ReadOnly)) { + printf("Failed to load input file '%s'\n", qPrintable(filename_)); + return; + } + + QDataStream in(&file); + + char *data; + uint size; + in.readBytes(data, size); + bool isTraceFile = size == 7 && qstrncmp(data, "qttrace", 7) == 0; + delete [] data; + if (!isTraceFile) { + printf("File '%s' is not a trace file\n", qPrintable(filename_)); + return; } - qDebug() << "Read paint buffer with" << buffer.numFrames() << "frames"; + in >> buffer >> updates; + printf("Read paint buffer with %d frames\n", buffer.numFrames()); resize(buffer.boundingRect().size().toSize()); @@ -157,14 +171,18 @@ int main(int argc, char **argv) { QApplication app(argc, argv); - if (argc <= 1) { - printf("Usage: %s filename\n", argv[0]); + if (argc <= 1 || qstrcmp(argv[1], "-h") == 0 || qstrcmp(argv[1], "--help") == 0) { + printf("Replays a tracefile generated with '-graphicssystem trace'\n"); + printf("Usage:\n > %s [traceFile]\n", argv[0]); return 1; } ReplayWidget *widget = new ReplayWidget(argv[1]); - widget->show(); - return app.exec(); + if (!widget->updates.isEmpty()) { + widget->show(); + return app.exec(); + } + } #include "main.moc" diff --git a/tools/qttracereplay/qttracereplay.pro b/tools/qttracereplay/qttracereplay.pro index 766ed04..cc5b98d 100644 --- a/tools/qttracereplay/qttracereplay.pro +++ b/tools/qttracereplay/qttracereplay.pro @@ -11,3 +11,5 @@ SOURCES += main.cpp target.path=$$[QT_INSTALL_BINS] INSTALLS += target + +CONFIG += console -- cgit v0.12
