KDirWatch issue

[Martin Koller]

Hi,

just wondering if I'm doing something wrong or there really is a bug in 
KDirWatch
(I'm on openSuse Leap 42.2, KF5 5.33.0)

From the docs I understand that when I call 

KDirWatch::stopDirScan(dir);
... create files in the dir ...
KDirWatch::restartDirScan(dir)

it should not emit the dirty signal when I run this, right ?

Well, it does.
I've attached a small test.

When I modify the code and use stopScan() ... create ... startScan()
I still receive the dirty signal with the path to the file I created.

Only way it works without signal is
removeDir(dir) ... create ... addDir(dir)

Is this how it's supposed to work ?
