[Bug 170758] New: high load when tagging

http://bugs.kde.org/show_bug.cgi?id=170758

Summary: high load when tagging
Product: digikam
Version: unspecified
Platform: Ubuntu Packages
OS/Version: Linux
Status: NEW
Severity: normal
Priority: NOR
Component: general
AssignedTo: [hidden email]
ReportedBy: [hidden email]

Version: (using KDE 3.5.9)
OS: Linux
Installed from: Ubuntu Packages

When associating tags, I encounter a substantial CPU load,
caused by (sometimes several) kio_digikamdates and
kio_digikamalbums processes.

The origin of this seems to be the following:
At some point one gets on the konsole:
"Noticed file change in directory /home/username/Pictures"
(i.e. the directory containing the database!)
this then triggers DIO::scan
which then calls in dio.cpp in
void Watch::slotDone(KIO::Job*)
Digikam::AlbumManager::instance()->refresh();
Digikam::AlbumLister::instance()->refresh();
I.e. those which then lead to the invocation of
kio_digikamalbums and kio_digikamdates.

Created an attachment (id=27339)
--> (http://bugs.kde.org/attachment.cgi?id=27339)
prevent kio_digikamalbums/dates (etc.) when database file is changed

Marcel pointed out to me on the mailing list that for 0.10, a solution
has been implemented.

The attached patch is a modified backport from the KDE4 version,
which ensures that data-base changes don't trigger a rescan.
