           Summary: When doing a face learning (erase data and rebuild)
                    from face UI recognition db is not erase and grow
    Classification: Unclassified
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED

          Priority: NOR
         Component: Face Management
          Assignee: digikam-devel at kde.org
          Reporter: e.longuemare at laposte.net

Reproducible: Sometimes

Steps to Reproduce:
1.Go to face management UI.
2.Go to option and check "reset and rebuild recognition data"
3.run
Actual Results:  
recognition.db isn't erase and data are added after existing datas 


Expected Results:  
Data are erased, and database is rebuild

I've done this a lot of time with expected result.
This time, it's don't work as expected.

What I have done before :
erase some empty folders in collection, with a sql request (not in digikam).
erase ImageHaarMatrix data in mysql db

Thank you,

Eric

PS : I have done a lot of facerecognition data rebuild for testing, with always
the same tags and face pictures, it's the first time this happen. The
recognition database has always the same size as I don't change anything in the
picture that are face tagged.

Workaround : go in /home/youruser/.kde/share/apps/likface/database,  save
recognition.db if you want then delete the file. Start or restart digikam (a
new empty file with about 13 ko is created)

Digikam Version : 4.0.0 beta from git
