| 1 | """Backfill to_address into DELETE rows that are move-source counterparts. |
| 2 | |
| 3 | When backfill_history_from_snapshots previously ran, move-source paths were |
| 4 | not recorded at all (the delete was suppressed). Now they are recorded with |
| 5 | op_payload.to_address pointing to the new path. |
| 6 | |
| 7 | This script finds existing DELETE rows that are missing to_address and |
| 8 | re-derives it by matching the corresponding MOVE row in the same commit |
| 9 | (same repo, same commit_id, move.op_payload.from_address == delete.address). |
| 10 | |
| 11 | Usage: |
| 12 | docker exec musehub python3 /app/deploy/backfill_move_to_address.py --dry-run |
| 13 | docker exec musehub python3 /app/deploy/backfill_move_to_address.py |
