Description Richard Mortimer 2017-07-25 21:07:53 UTC

Previous versions of the MySQL digikam database schema did not enforce referential integrity and hence can have inaccessible orphan rows in the database.

During migration digikam needs to take care to ignore these rows so that the migration can continue without manual cleanup of the original MySQL database first.

I have a patch against current git. This has been tested using the 5.7.0 and 5.6.0 pre-release app images during a migration of my digikam 4.x MySQL data to 5.x digikam.

Created attachment 106864 [details]
Ignore orphan rows in MySQL migration

This can be tested on an existing digikam installation by replacing /usr/share/digikam/database/dbconfig.xml with a patched copy and then restarting digikam.
