A modified mergeresources.py that exposes this behavior.

Version:           4.6 (using KDE 4.6.0) 
OS:                Linux

I have been playing around with the resource merging in playground:
http://websvn.kde.org/trunk/playground/base/nepomuk-kde/toolbox/mergeresources.py

Using the following query one finds hundreds of duplicates:
select distinct ?people count(?r) where { ?r a nco:PersonContact . ?r nco:fullname ?people . }

I tried to merge these and I noticed a huge improve in queries afterwards.

Reproducible: Always

Steps to Reproduce:
Install and make use of the nepomuk email, calendar and contact feeders.

Actual Results:  
A duplicate resource is created in nepomuk every time the feeder starts.

Expected Results:  
Each task, contact, email, etc. should only be fed to nepomuk once. Feeders should properly check for this.

I am posting a modified mergeresources.py that exposes this behavior.

The same for audio files. I think that the problem is related to a bad serialization, a bad transaction or both problems at the same time.

Although the situation has incredibly improved with the new nepomuk feeder, I am still getting some duplicates, especially with my own e-mail. I am also seeing "MERGING FAILED!" messages during indexing.

Is this related? I guess so.

not sure if e91113b8e0956b8ac8ae7614a2b1faa7dfbed0f0 in kdebase-runtime fixes this.

Adding vhanda

After some time running the new nepomukfeeder I have no more nco:PersonContact duplicates. I still have duplicate tags, especially the "Birthday" tag is still not being merged properly.

Comment 6 Luis Silva 2012-01-15 12:16:26 UTC

No more duplicates in kde 4.8. Thanks
