If QProcess is called with non existence command/binary it leaks file descriptor.
void testfn()
{
QProcess process;
process.start("nonexistingcommand");
process.waitForFinished();
process.closeReadChannel(QProcess::StandardOutput); process.closeReadChannel(QProcess::StandardError);
process.closeWriteChannel();
process.close();
}
int main(int argc, char** argv)
{
QCoreApplication app(argc, argv);
for(int i = 0; i < 10; ++i){
testfn()
}
return 0;
}
When diffing the 'lsof' output between two timepoints, You get following difference:
