[Qt-interest] bash jobcontrol breaks QT4 and inotify ?

[David Heremans]

Hello,

I was trying to find a nice way to have my program react upon new files
that could pop-up in a given /var/spool directory. Since it runs on a
linux box  I thought about using inotify, and a quick Google got me to
this page:

http://wahjava.wordpress.com/2007/05/09/my-experiment-with-inotify-and-qt4/

I downloaded the small example inotify.tgz and it worked as a charm so I
decided to try to integrate the inotify.hh and inotify.cc into my
program, but it doesn't seem to work correctly, so I had to look at the
example again and (by accident) I found the following strange behavior.

If I launch the ./inotify_demo (from an xterm/konsole) and start
monitoring a directory it works nicely. But if a press CTRL-Z and bring
it back to the foreground (with the fg command) it simply stops reacting
to changes? Even pressing the stop/start button doesn't reactivate the
program.

Can somebody here explain me the impact of the CTRL-Z on the inotify
mechanism? Could it be that running my program in the debugger doesn't
work because of some unknown-to-me impact from signals (on  the threads?)

I'm running kubuntu lucid lynx (64 bit)
with qtcreator 1.3.1, based on qt 4.6.2(64 bit)

Thanks in advance,
