|
|
* Fix duplicate entries in oc_lucene_status
|
|
*
|
|
* search_lucene prior to v0.5.0 did not have a primary key on the lucene_status table. Newer versions do, which
|
|
* causes the migration check to fail because it tries to insert duplicate rows into the new schema.
|
|
*
|
|
* FIXME Currently, apps don't have a way of repairing anything before the migration check:
|
|
* @link https://github.com/owncloud/core/issues/10980
|
|
*
|
|
* As a result this repair step needs to live in the core repo, although it belongs into search_lucene:
|
|
* @link https://github.com/owncloud/core/issues/10205#issuecomment-54957557
|
|
*
|
|
* It will completely remove any rows that make a file id have more than one status:
|
|
* fileid | status fileid | status
|
|
* --------+-------- will become --------+--------
|
|
* 2 | E 3 | E
|
|
* 2 | I
|
|
* 3 | E
|
|
*
|
|
* search_lucene will then reindex the fileids without a status when the next indexing job is executed
