Package: jdupes
Version: 1.27.3-5~bpo12+1
Severity: normal
Tags: upstream
X-Debbugs-Cc: [email protected]
Dear Maintainer,
jdupes_1.27.3-1 and later have a high miss rate in detecting unique files.
I tried to report the bug upstream but the github is archived and read only,
and codeberg does not have issues enabled.
To locate the introduction of this bug I tried all debian snapshots versions.
jdupes_1.26.1-1~bpo12+1 was the most recent to work correctly.
I use fclones as reference because it seems 100% correct. I could not find an
error in its detection results.
fclones:
unique files:

jdupes_1.26.1-1~bpo12+1 correctly finds the 64 unique files but the recent
jdupes only finds 10. This number corresponds to the 10 candidates after
grouping by size and path in fclones, so that might be a clue for the location
of the bug.

Changes:
jdupes (1.28.0-1+deb13u1) trixie; urgency=medium
.
* debian/patches/020_fix-uniq-count.patch: created to fix flag overlap
between FF_NOT_UNIQUE and FF_HASHDB_DIRTY.
.
Both FF_NOT_UNIQUE and FF_HASHDB_DIRTY were defined using the same
bit (1U << 5), causing logic errors where files were incorrectly
marked as not unique due to hash database state. This commit moves
FF_HASHDB_DIRTY to (1U << 6) to eliminate the overlap. It fixes
incorrect behavior when detecting unique files with --unique or -u.
.
Closes: #1063079
