/** |
|
27
|
|
|
* TYPO3 v11 does not need a "versioned" / "placeholder" pair for newly created records in a version anymore. |
|
28
|
|
|
* |
|
29
|
|
|
* This upgrade wizards merges those records pairs into one record. |
|
30
|
|
|
* |
|
31
|
|
|
* The strategy is to keep the t3ver_state=1 record and to merge "payload" fields data like |
|
32
|
|
|
* "header / bodytext" and so on from the t3ver_state=-1 record over to the t3ver_state=1 records. |
|
33
|
|
|
* The t3ver_state=-1 record is then deleted (or marked as deleted if the table is soft-delete aware). |
|
34
|
|
|
* |
|
35
|
|
|
* For relations, this is a bit more tricky. When dealing with CSV and ForeignField relations, |
|
36
|
|
|
* existing relations are connected to the t3ver_state=1 record. This is fine. For MM relations, |
|
37
|
|
|
* they point to the t3ver_state=-1 record, though. The implementation thus finds and updates |
|
38
|
|
|
* those MM relations. |
|
39
