* tart pull: try to re-use APFS blocks by cloning the base image * Punch a hole when a zero chunk is detected * Properly retrieve errno when hole punching operation fails * tart pull: do not retry on RuntimeError * Ensure that the holes we're about to punch are FS block size-aligned * VMDirectory: remove unused static variables * tart pull: log if we've found an image to deduplicate against * Do not prematurely read contents from disk * Only consider candidates with deduplicatedBytes more than 0 * APFS reuse UX/DX improvements (#870) * Show how much deduplication happening Improvement to the APFS deduplication logic which checks whether a disk image file `mayShareFileContent` with some other file, and then we put a custom attribute to track the deduplication since there is no way to get this information from APFS itself. It's not 100% accurate but given that OCI cache is immutable the actual disk usage can only be lover than that. * Use string attribute * Update Sources/tart/URL+Prunable.swift Co-authored-by: Nikolay Edigaryev <edigaryev@gmail.com> * Added SizeOnDisk colume --------- Co-authored-by: Nikolay Edigaryev <edigaryev@gmail.com> --------- Co-authored-by: Fedor Korotkov <fedor.korotkov@gmail.com>
