Bug#457968: diff reports binary file differences, which are highly unlikely
On Fri, 28 Dec 2007, Tim Blechmann wrote: What do you mean by large binary files? Does it happen with files smaller than 2GB? definitely smaller than 2gb ... `large binary files' are flac-encoded audio files of several hundred mb ... That's good news, as it means most probably the bug has nothing to do with Large File Support. In either case, I need a way to reproduce the bug. Please try to find a smaller pair of files using the dd command. For example, if diff thinks the files are different after reading the first 50Mb of each, then you can cut the files and keep only the first 50Mb of each. Hopefully this method would produce a smaller pair of files. Does it happen with diff 2.8.7 in experimental? What about cmp -l file1 file2? will check this tomorrow ... It's 2008 now.

Bug#457968: diff reports binary file differences, which are highly unlikely
Package: diff Version: 2.8.1-12 Severity: important when copying large binary files from one partition to another, i used diff to verify, that copying the data worked correctly. diff reports 'binary files differ' for a few files, though. comparing the file checksums, the files don't differ, though. i tested it with both md5 and sha512 checksums ... so it is highly unlikely that it is a problem with the files, but rather a bug in diff ... hth, tim -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (500, 'stable'), (10, 'experimental') Architecture: i386 (i686) Kernel: Linux 2.6.23.12-rt14-686 (SMP w/2 CPU cores; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages diff depends on: ii libc6 2.7-4 GNU C Library: Shared libraries diff recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Just likely to be a bug in diff is not enough. Please provide more evidence that it's diff and not your computer's hardware (either memory, hard disk, CPU, or whatever). Otherwise I will close this bug. Thanks. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
