Andrea Mazzoleni	275063d23c	Track deallocated files in the content file for parity recovery ... Add a new 'dealloc' list per disk to record files that were removed or modified during a scan. This list is saved in the content file (new format version SNAPCNT4) so that past parity contributions of those files can be imported from previous snapshots.	2026-08-18 23:33:52 +02:00
Andrea Mazzoleni	54602422dd	Change commenting style	2026-08-18 23:33:52 +02:00
Andrea Mazzoleni	1227a8c45e	Sync no longer requires clearing the past hash ... It no longer assumes past hashes are valid if even a single unsynced block exists, which indicates a previous sync was interrupted. While this makes syncing slower after an interruption, it preserves the past hash in the content file, enabling a more reliable fix if a disk fails following an incomplete sync. This ensures the --import option remains functional even after an interrupted sync.	2026-08-18 23:33:52 +02:00
