Bug 96648 – Replace qInstallMsgHandler() with qInstallMessageHandler()

• Status: RESOLVED FIXED

[Kai Koehne]

In qt5 / qtbase, qInstallMsgHandler() got deprecated, and replaced by qInstallMessageHandler. QtWebkit should use the new API.

Just a sidenote, I've found this about qPrintable:
http://lists.trolltech.com/qt-interest/2007-12/thread00508-0.html

Is this still valid? if so we could use .constData() as in:
http://qt-project.org/doc/qt-5.0/qtglobal.html#qInstallMessageHandler

[Kai Koehne]

qPrintable(string) 

is actually just a macro that expands to

QString(string).toLocal8Bit().constData() 

The e-mail of qt-interest was about whether the temporary QByteArray created by toLocal8Bit() is guaranteed to be still valid by the time printf(...) is executed, and the answer (at the bottom of the thread) is that it is: It can only be destroyed after the whole statement has executed. So

printf("%s", qPrintable(x));

is okay while

const char * str = qPrintable(x);
printf("%s", str);

isn't.

As the purple bubbles indicate your patch does not apply. Could you update it to WebKit trunk so that the early warning system and the commit queue can process it.
