those to the report. + update configure macros + update config.guess, config.sub 2015/07/07 (diffstat 1.60) + handle double-quotes, e.g., from diffutils 3.3 when filenames have embedded spaces. + add configure option --with-man2html + update configure macros + update config.guess, config.sub 2014/06/05 (diffstat 1.59) + add -E option to filter escape-sequences, e.g., from colordiff (Ubuntu #1304262). + merge/adapt improvments to makefile and configure script from openembedded.org (forwarded by Ross Burton). + remove unused $(libdir) from makefile "installdirs" target + amend definition in CF_POPEN_TEST to permit use of autoheader. + workaround for gratuitous renaming of AC_ACVERSION in 2.69 + added "docs" rule to makefile + improvements to configure macros: + added check for

add COPYING file (request by Dagobert Michelsen). + improved portability for cross-compiling, by supplying missing getopt function as well as improving checks for popen/pclose prototypes. + updated configure macros, e.g., for MingW and MSYS fixes. + update config.guess, config.sub 2013/04/15 (diffstat 1.57) + improve treatment of binary files in ambiguous message introduced in diffutils 2.8.4, and finally corrected in 3.0 (report by Moritz Barsnick). 2013/02/11 (diffstat 1.56) + add -K option which attempts to improve the annotation of "only" files by looking for a match in the resulting set of files and inferring whether the file was added or removed (request by Marc Haber). + add check of command-line options for valid numbers. + improve merging of patches for the same filename (report/testcase by Paul E McKenney). + document -d option in manpage. + document -b, -C, -s option in usage (patch by Tim Waugh, RedHat #852770) + modify configure script as done for byacc in 2012/10/03, making the 2.52-patches the prerequisite and adding support for --datarootdir option. + update config.guess, config.sub + add logic to handle SVN diffs when the pathnames contain spaces (patch by Stuart Prescott, Debian #675475). + fix typo in package/debian/control 2012/01/03 (diffstat 1.55) + add -R option, like patch's, to reverse the order of the comparison. + FreeBSD ports/148604, ports/149500 reported that lzcat may not support extracting files compressed in xz format (patch by Frederic Culot, FreeBSD #149500). + address documentation issue raised in Novell #739210 + correct typo s/Solaris/Solar/. + updated configure script macros: CF_ANSI_CC_CHECK CF_DISABLE_LEAKS CF_GCC_ATTRIBUTES CF_GCC_WARNINGS CF_MAKE_TAGS CF_MSG_LOG CF_PATH_PROG

hyphens vs dashes in manpage per http://lintian.debian.org/tags/hyphen-used-as-minus-sign.html (patch by Francois Marier). + drop mkdirs.sh, use "mkdir -p" + add configure checks for ctags and lint. + updated configure macros + reformat CHANGES to work with metrics script. + fix strict gcc warnings, e.g., using const. + improve a case where filenames have embedded blanks (patch by Reinier Post). + update config.guess, config.sub 2009/11/07 (diffstat 1.51) + correct suffix-check for ".xz" files as command-line parameters rather than as piped input (report by Moritz Barsnick). 2009/11/6 (diffstat 1.50) + build/test fixes for MSYS, i.e., MinGW. + improve configure check for get_unlocked function. + use $TMPDIR for path of temporary file used in decompression. + correct else-condition for detecting compression type (patch by Zach Hirsch). 2009/08/31 (diffstat 1.49) + improve lzma support, add support for xz (patch by Eric Blake). + add special case for no-newline message from some diff's (Ubuntu #269895). + improve configure check for getopt header. + add configure special case for HPUX 11 with _XOPEN_SOURCE definition. + update config.guess, config.sub 2009/08/11 (diffstat 1.48) + add decompression tests for lzma and pack file types. + check for zcat and uncompress in preference to "compress -dc". + modify to check the first few bytes of standard input, and use a corresponding decompression utility if the stream appears to be compressed. This requires making a temporary copy of the data (Debian #491575). + add -N option, to truncate filenames. + use getc_unlocked() rather than fgetc_unlocked() + modify to recognize Perforce-style diffs (patch by Ed Schouten). + updated configure macros to improve compiler warning checks, use $PATH_SEPARATOR rather than $PATH_SEP (for consistency with some autoconf versions), + fix typo in configure --with-install-prefix option (report by Dagobert Michelsen). + update config.guess, config.sub 2009/03/29 (diffstat 1.47) modify to work with patch ".rej" files, which do not have a header to tell which file is affected. fix typo in usage message (reports by Moritz Barsnick, John McNamara, Richard Quadling). 2008-08-06 (diffstat 1.46) + add "-S", "-D" and "-m" options to provide a way to show the amount of difference relative to the total sizes of the files. + add "-q" option (Debian #488248, patch by Greg Norris). 2007/09/04 (diffstat 1.45) + add "-b" option (Debian #379380, patch by Greg Norris). 2007/08/26 (diffstat 1.44) + add a check for default-diff output, e.g., "diff foo bar|diffstat", which has no "diff" command in the output for diffstat to guess that a diff is beginning. + add a check after completing a chunk for unified diff to ensure that the next line either begins another chunk for the diff, or starts another diff, e.g., a context diff (report by Adrian Bunk). + add configure options for leak-checking valgrind, etc. + use install-sh rather than install.sh + updated config.guess and config.sub + updated configure macros CF_GCC_ATTRIBUTES CF_GCC_WARNINGS CF_MSG_LOG CF_PATH_SYNTAX CF_VERBOSE CF_XOPEN_SOURCE 2006/07/16 (diffstat 1.43) + fix to avoid modifying data which is being used by tsearch() for ordering the binary tree (report by Adrian Bunk). 2006/07/02 (diffstat 1.42) + do not ignore pathnames in /tmp/, since some tools create usable for both old/new files there (Debian #376086). + correct ifdef for fgetc_unlocked(). + updated configure macros CF_GCC_VERSION, CF_PATH_SYNTAX and CF_XOPEN_SOURCE + add configure check for compress, gzip and bzip2 programs that may be used to decompress files. 2005/08/24 (diffstat 1.41) + update usage message for options added in 1.40 (report by Eric Blake). 2005-08-15 (diffstat 1.40) + add options -l, -r and -t. add to -f option (patch, comments by Jean Delvare, Michael Burian). + improve I/O on Linux using fgetc_locked(). + improve searching of long sorted lists using tsearch() + improve configure-script checks for Intel compiler warnings. 2005-04-10 (diffstat 1.39) + change order of merging and prefix-stripping so stripping all prefixes, e.g., with -p9, will be sorted as expected (patch by Jean Delvare). + correct a reference to freed memory after merging found with valgrind. 2005-01-16 (diffstat 1.38) + add makefile.wnt, etc., for win32 port. + fix "make check" to work even when PATH or the build directory has spaces in it (patch by Eric Blake). + add support for '--help' and '--version' command line arguments, for a consistent interface with GNU tools, and still compatible to POSIX requirements on utility options (patch by Eric Blake). 2004-12-18 + modify makefile.in and run_test.sh to allow "make check" to be run from a build directory which is not the same as the source directory, i.e., when the configure --srcdir option is used (request by Eric Blake). + modify distribution to include sample of regression tests, so a "make check" will work (request by Eric Blake). 2004-12-16 (diffstat 1.37) + fix a different case for data beginning with "--" which was treated as a header line. 2004-12-14 (diffstat 1.36) + Fix allocation problems. Open files in binary mode for reading. Getopt returns -1, not necessarily EOF. Add const where useful. Use NO_IDENT where necessary. malloc() comes from <stdlib.h> in standard systems (Patch by Eric Blake <ebb9@byu.net>.) 2004-11-08 (diffstat 1.35) + modify makefile.in to work with configure --srcdir option (report by Eric Blake). + minor fix for resync of unified diffs checks for range (line beginning with '@' without header lines (successive lines beginning with "---" and "+++") (Debian #264098). + miscellaneous updates for configure script 2003-11-09 (diffstat 1.34) + improve check for certain lines (not those that begin a chunk) that begin with '-', treating all except "---" as a delete (report by James Rowe <Jay@jnrowe.uklinux.net>). + minor updates to configure script. 2003-02-14 (diffstat 1.33) + modified to work around a case where the filename+date was incomplete, i.e., missing one of the components such as the day of the month. While diffstat does not use the date directly, it helps distinguish some lines from non-patches (report by Moritz Barsnick <moritz@barsnick.net>). + add "-h" option (request by Moritz Barsnick). + fix a typo in usage message (report by Moritz Barsnick). + add "-e" and "-o" options to simplify testing on OS/2 EMX. 2003-01-04 (diffstat 1.32) + modified to handle patches generated by makepatch-2.00_09, which uses both "Index" and "diff" lines (report by D Roland Walker). As a side effect, the additional merging eliminates occasional reports with zero differences. + modified to avoid buffer overflows. + fixes for Debian #155000 (did not handle a '-' in first content-column of a unified diff) and Debian #170947 (option to turn the progress messages off). + updated configure script using aclocal.m4 macros + update makefile.in to improve use of autoconf (report/patch by Nix <nix@esperi.demon.co.uk>). 2002-08-20 (diffstat 1.31) + add -u, -k options to override diffstat's normal sorting (-u) and merging (-k) of identical filenames. (-u requested by H Peter Anvin <hpa@zytor.com>). 2002-08-09 (diffstat 1.30) + allow either '/' or '-' as delimiters in dates, to accommodate gendiff (report by Rik van Riel <riel@conectiva.com.br>). This corresponds to the time format used in diffutils 2.8 whose changelog states that this is ISO 8601 (though online references differ). 2001-10-10 (diffstat 1.29) + add bzip2 (.bz2) suffix (suggested by Gregory T Norris <haphazard@socket.net>, Debian #82969). + add check for diff from RCS archive where the "diff" lines do not reference a filename. 2000-03-29 (diffstat 1.28) + Add -c option (to prefix output with '#' comment), eliminating a step in my script that combines diffstat output with a patch. This is a workaround for OSF1's broken sed utility. + Check for compressed file suffixes .Z and .gz, read uncompressed data via pipe (Debian #53975 by ch@lathspell.westend.com). + Simplified makefile based on comments by M Sweger <mikesw@whiterose.net> + Adapted changes from Troy Engel <tengel@sonic.net> as "-f" option. 1998-05-27 (diffstat 1.27) + Debian diff's don't show dates on the lines where we expect to see filenames. 1998-01-16 (diffstat 1.26, Patch 5) + Change copyright terms. + Accommodate patches w/o tabs in header lines (e.g., from cut/paste). Still prefer the tabs because otherwise we cannot have spaces in filenames. + Strip suffixes such as ".orig", to avoid confusing output. 1996-03-16 (diffstat 1.24, Patch 4) + Corrected state-transition after "Binary". + Added testing subdirectory + Added -p option. + Handle differences from /tmp (e.g., for X11R5 patches). 1995-05-06 (diffstat 1.17, Patch 3) + Repost whole program to comp.sources.misc (1.17) + Mods to scaling: limit to 1:1 if only a few changes were made; added logic to accumulate error across +/-/! calls. + added logic to recognize 'rcsdiff -u' output. 1994-12-26 (diffstat 1.15, Patch 2) + Strip common pathname prefix (1.15) 1994-11-13 (diffstat 1.14, Patch 1) + Test for <string.h> vs <strings.h> + Corrected error in 'match()' that didn't handle properly the case when an argument was a null string (i.e., blank lines in a unified diff). + Added options '-n' and '-V' + Added patchlev.h, CHANGES files. + Added install.sh, for autoconf 2.1 1994-06-13 (diffstat 1.12, Patch 0) + Initial release of 'diffstat' (1.12).
