Andrea Mazzoleni	76998613da	Remove the unused number of data disks from the vector allocation ... The same addressing rules are applied to the parity disks because they are used as data disks during recovery operations.	2026-08-18 23:33:54 +02:00

Andrea Mazzoleni	76ce1cbb16	Add regression check for Btrfs ... It requires root privileges as it has to create Btrfs filesystems.	2026-08-18 23:33:52 +02:00
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
