thumbnails always rebuilt using mysql

[Johannes Wienke-3]

Hi,

I just tried to move my collection to mysql and noticed that something
must be broken with the thumbnail handling in the mysql backend. If I
switch to mysql using a separate schema for thumbnails, the thumbnails
are rebuilt each time I start digikam. Moreover, after restarting, the
thumbnails schema name field in the settings is empty. Can anyone
confirm this?

Regards,
Johannes

You use a separate schema for thumbnails ?

Yes, but the settings problem also occured when using the same schema.

Hi Johannes,

 

we  don't handled thumbnails database name on read/save config in the right manner.

So this value was always the same schema name. Fixes the the latest svn revision on the

stable svn tree your problem?

 

If it still exists, please check out the console output, maybe there is something interesting...

Try also to restart digikam after changing your settings.

 

Greetings,

Holger

There was a bug in the MySQL thumbnails schema that the hashes were truncated.
This is fixed since we really activated the schema update in the branch
yesterday.

But normally, it should fallback to using lookup by filename.

If the problem is fixed in the branch, I can live with not knowing the exact
problem.
If it's still not fixed, we'll have to look into that further.

Marcel
