\section issue-cmdline Issues with command line arguments

QCoreApplication::arguments() returns a QStringList that containing at
|
|
most 32 arguments and drops the rest. The full list of arguments is
|
|
accessible through \c argc and \c argv. They can be converted into
|
|
QStringList similar to returned by QCoreApplication::arguments() as
|
|
follows:
|
|
|
|
\code
|
|
M_EXPORT int main(int argc, char **argv) {
|
|
QStringList arguments;
|
|
for (int a = 0; a < argc; ++a) {
|
|
arguments << QString::fromLocal8Bit(argv[a]);
|
|
}
|
|
...
|
|
\endcode

\section issue-watchdog Issues with scripts, D-Bus, and process monitoring
|
|
|
|
By default, invoker processes terminate before or right after booster
|
|
processes have called main(). This may confuse shell scripts and
|
|
process monitoring in D-Bus daemon and Upstart, for instance. To help
|
|
solving these issues invoker accepts parameters
|
|
|
|
\li \c --delay \c 10 invoker waits for 10 seconds before terminating
|
|
\li \c --wait-term invoker will not terminate until the launched
|
|
application terminates. Invoker will return the same return value as
|
|
the application did, or it will be terminated by the same signal as
|
|
the launched application. Signals received by the invoker process will
|
|
be forwarded to the launched application.
|
|
|
|
\section forking Forking
|
|
|
|
It's not possible to use MComponentCache or MDeclarativeCache in the child
|
|
process if you fork() in your application. This is just due to the fact that
|
|
X11 connections get messed up after fork().
|
|
|
|
\section crashes Crashes after application's main()
|
|
|
|
If an application is launched with invoker, there may be some
|
|
destructors of MeeGo Touch classes executed after application's
|
|
main(). This can cause crashes, if the application has installed a
|
|
custom debug message handler and didn't uninstall it before exit.
