[Octave-bug-tracker] [bug #42242] Octave does not always execute most recently saved file in an NFS directory

[Torsten]

Follow-up Comment #19, bug #42242 (project octave):

The function that is used for all save actions contains the following code


// save the contents into the file
QTextStream out (&file);
QApplication::setOverrideCursor (Qt::WaitCursor);
out << _edit_area->text ();
out.flush ();
QApplication::restoreOverrideCursor ();
file.flush ();
file.close ();


>From the Qt-docs:

* QTextStream::flush (): Flushes any buffered data waiting to be written to
the device.
* bool QFile::flush (): Flushes any buffered data to the file. Returns true if
successful; otherwise returns false.

The file is flushed but there is no check whether the flush was successful.
Can it happen that a flush fails on NTFS directories? I can prepare a patch
that adds that check. But what should be done if flush returns false?
