Package: wdiff Version: 1.2.2-6 Severity: normal wdiff is broken when the input contains a null character. For instance, create 2 files a and b with
printf "a\n2\n3\n4\n5\n6\n7\n8\n" > a printf "b\n2\n3\n4\n5\n6\n7\n8\n\000\n" > b $ wdiff a b b 2 3 4 5 6 7 8 instead of something like [-a-]{+b+} 2 3 4 5 6 7 8 {+^@+} Similarly, the following is incorrect: $ diff -au a b | wdiff -d ++ b 2024-02-09 14:11:23.981863795 +0100 @@ -1,4 +1,4 @@ b 2 3 4 @@ -6,3 +6,4 @@ 6 7 8 There is no such issue if I replace \000 by \001. So this is specific to the null character. -- System Information: Debian Release: trixie/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable-debug'), (500, 'proposed-updates-debug'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.6.13-amd64 (SMP w/12 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages wdiff depends on: ii libc6 2.37-15 ii libtinfo6 6.4+20240113-1 wdiff recommends no packages.
