Subject: [PATCH] libtracker-data: Avoid deletion of empty rows in FTS table
|
||
|
|
|
||
|
|
Starting with SQLite 3.34.0, this turns into a consistency error. Ensure
|
||
|
|
rows being deleted have actually some content before proceeding to deletion,
|
||
|
|
and ensure we don't process individual properties one by one in the course
|
||
|
|
of a whole rdfs:Resource deletion.
|
||
|
|
|
||
|
|
