Debug/Test tool to exercise a btrfs ioctl for deduplicating file regions.
GPL-2.0-only
* Thu Sep 14 2023 pgajdos@suse.com
- build for 15
* Mon Jul 17 2023 mvetter@suse.com
- Update to 0.12:
* Duplication lookup is now based on extents. This leads to a
massive increase of the performances. Block-based lookup is
still possible via --dedupe-options=partial.
* Following that change, a new hashfile format has been introduced.
Previous hashfile format is still supported when extents lookup
are disabled, this is not recommended.
* Batching has been implemented. When enabled with the -B <batchsize>
option, duperemove will run the deduplication phase every <batchsize>
scanned files. This is meant to help running duperemove on large
dataset, with small blocksize, or on memory-constrained systems.
* All hash algorithm has been removed and replaced by xxh128. This
variant is as robust as murmur3 while being faster. Choosing a
hash function via the --hash option has been removed. Hashfiles
built with other algorithm must be removed.
* Thu Feb 03 2022 mvetter@suse.com
- Update to 0.11.3:
* Increase open file limit. (#269)
* Create hash database file with 600 permission for improved
security. (#262)
* Read more data per pread, for v2 hashfile format this reduces
the overall number of syscalls made which in turns results
in better performance.
* Fix truncated file handling, eliminating a an infinite
loop case. (#255)
