Windows: Document change of behavior for QCoreApplication::arguments()

    XMLWordPrintable

Details

    Description

      The handling of arguments masked with ' (ASCII char 0x27) has changed in 5.1 on Windows. QCoreApplication will report the original PATH, while Qt 5.1 stripped the ':

      #include <QCoreApplication>
#include <QDebug>
#include <QStringList>
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    qDebug() << "QCoreApplicaton::arguments().last(): " << qPrintable(a.arguments().last());
}

      run with 5.1:

      test.exe 'hello'
QCoreApplicaton::arguments().last():  hello

      with 5.2:

      test.exe 'hello'
QCoreApplicaton::arguments().last():  'hello'

      Since this might possibly affect a lot of applications, it should at least be documented. The change of behavior is most likely caused by https://codereview.qt-project.org/#change,64127 .
