  30
  31 2010/07/19 (diffstat 1.53)
  32
  33         + add missing "break" statement which left "-c" option falling-through

  60         + fix strict gcc warnings, e.g., using const.
  61
  62         + improve a case where filenames have embedded blanks (patch by Reinier
  63           Post).
  64
  65         + update config.guess, config.sub
  66
  67 2009/11/07 (diffstat 1.51)
  68
  69         + correct suffix-check for ".xz" files as command-line parameters

  82
  83 2009/08/31 (diffstat 1.49)
  84
  85         + improve lzma support, add support for xz (patch by Eric Blake).
  86
  87         + add special case for no-newline message from some diff's (Ubuntu

  96 2009/08/11 (diffstat 1.48)
  97
  98         + add decompression tests for lzma and pack file types.
  99
 100         + check for zcat and uncompress in preference to "compress -dc".
 101
 102         + modify to check the first few bytes of standard input, and use a
 103           corresponding decompression utility if the stream appears to be
 104           compressed.  This requires making a temporary copy of the data
 105           (Debian #491575).
 106
 107         + add -N option, to truncate filenames.
 108
 109         + use getc_unlocked() rather than fgetc_unlocked()
 110
 111         + modify to recognize Perforce-style diffs (patch by Ed Schouten).
 112
 113         + updated configure macros to improve compiler warning checks, use
 114           $PATH_SEPARATOR rather than $PATH_SEP (for consistency with some
 115           autoconf versions),
 116
 117         + fix typo in configure --with-install-prefix option (report by
 118           Dagobert Michelsen).
 119
 120         + update config.guess, config.sub
 121
 122 2009/03/29 (diffstat 1.47)
 123
 124         modify to work with patch ".rej" files, which do not have a header to
 125         tell which file is affected.
 126
 127         fix typo in usage message (reports by Moritz Barsnick, John McNamara,
 128         Richard Quadling).
 129
 130 2008-08-06 (diffstat 1.46)
 131
 132         + add "-S", "-D" and "-m" options to provide a way to show the amount
 133           of difference relative to the total sizes of the files.
 134
 135         + add "-q" option (Debian #488248, patch by Greg Norris).
 136
 137 2007/09/04 (diffstat 1.45)
 138
 139         + add "-b" option (Debian #379380, patch by Greg Norris).
 140
 141 2007/08/26 (diffstat 1.44)
 142
 143         + add a check for default-diff output, e.g., "diff foo bar|diffstat",
 144           which has no "diff" command in the output for diffstat to guess that
 145           a diff is beginning.
 146
 147         + add a check after completing a chunk for unified diff to ensure that
 148           the next line either begins another chunk for the diff, or starts
 149           another diff, e.g., a context diff (report by Adrian Bunk).
 150
 151         + add configure options for leak-checking valgrind, etc.
 152
 153         + use install-sh rather than install.sh
 154
 155         + updated config.guess and config.sub
 156
 157         + updated configure macros CF_GCC_ATTRIBUTES CF_GCC_WARNINGS CF_MSG_LOG
 158           CF_PATH_SYNTAX CF_VERBOSE CF_XOPEN_SOURCE
 159
 160 2006/07/16 (diffstat 1.43)
 161
 162         + fix to avoid modifying data which is being used by tsearch() for
 163           ordering the binary tree (report by Adrian Bunk).
 164
 165 2006/07/02 (diffstat 1.42)
 166
 167         + do not ignore pathnames in /tmp/, since some tools create usable
 168           for both old/new files there (Debian #376086).
 169
 170         + correct ifdef for fgetc_unlocked().
 171
 172         + updated configure macros CF_GCC_VERSION, CF_PATH_SYNTAX and
 173           CF_XOPEN_SOURCE
 174
 175         + add configure check for compress, gzip and bzip2 programs that may be
 176           used to decompress files.
 177
 178 2005/08/24 (diffstat 1.41)
 179
 180         + update usage message for options added in 1.40 (report by Eric Blake).
 181
 182 2005-08-15 (diffstat 1.40)
 183
 184         + add options -l, -r and -t.  add to -f option (patch, comments by
 185           Jean Delvare, Michael Burian).
 186
 187         + improve I/O on Linux using fgetc_locked().
 188
 189         + improve searching of long sorted lists using tsearch()
 190
 191         + improve configure-script checks for Intel compiler warnings.
 192
 193 2005-04-10 (diffstat 1.39)
 194
 195         + change order of merging and prefix-stripping so stripping all prefixes,
 196           e.g., with -p9, will be sorted as expected (patch by Jean Delvare).
 197
 198         + correct a reference to freed memory after merging found with valgrind.
 199
 200 2005-01-16 (diffstat 1.38)
 201
 202         + add makefile.wnt, etc., for win32 port.
 203
 204         + fix "make check" to work even when PATH or the build directory has
 205           spaces in it (patch by Eric Blake).
 206
 207         + add support for '--help' and '--version' command line arguments, for a
 208           consistent interface with GNU tools, and still compatible to POSIX
 209           requirements on utility options (patch by Eric Blake).
 210
 211 2004-12-18
 212
 213         + modify makefile.in and run_test.sh to allow "make check" to be run
 214           from a build directory which is not the same as the source directory,
 215           i.e., when the configure --srcdir option is used (request by Eric
 216           Blake).
 217
 218         + modify distribution to include sample of regression tests, so a
 219           "make check" will work (request by Eric Blake).
 220
 221 2004-12-16 (diffstat 1.37)
 222
 223         + fix a different case for data beginning with "--" which was treated
 224           as a header line.
 225
 226 2004-12-14 (diffstat 1.36)
 227
 228         + Fix allocation problems.  Open files in binary mode for reading.
 229           Getopt returns -1, not necessarily EOF.  Add const where useful.  Use
 230           NO_IDENT where necessary.  malloc() comes from <stdlib.h> in standard
 231           systems (Patch by Eric Blake <ebb9@byu.net>.)
 232
 233 2004-11-08 (diffstat 1.35)
 234
 235         + modify makefile.in to work with configure --srcdir option (report by
 236           Eric Blake).
 237
 238         + minor fix for resync of unified diffs checks for range (line beginning
 239           with '@' without header lines (successive lines beginning with "---"
 240           and "+++") (Debian #264098).
 241
 242         + miscellaneous updates for configure script
 243
 244 2003-11-09 (diffstat 1.34)
 245
 246         + improve check for certain lines (not those that begin a chunk) that
 247           begin with '-', treating all except "---" as a delete (report by
 248           James Rowe <Jay@jnrowe.uklinux.net>).
 249
 250         + minor updates to configure script.
 251
 252 2003-02-14 (diffstat 1.33)
 253
 254         + modified to work around a case where the filename+date was incomplete,
 255           i.e., missing one of the components such as the day of the month.
 256           While diffstat does not use the date directly, it helps distinguish
 257           some lines from non-patches (report by Moritz Barsnick
 258           <moritz@barsnick.net>).
 259
 260         + add "-h" option (request by Moritz Barsnick).
 261
 262         + fix a typo in usage message (report by Moritz Barsnick).
 263
 264         + add "-e" and "-o" options to simplify testing on OS/2 EMX.
 265
 266 2003-01-04 (diffstat 1.32)
 267
 268         + modified to handle patches generated by makepatch-2.00_09, which uses
 269           both "Index" and "diff" lines (report by D Roland Walker).  As a side
 270           effect, the additional merging eliminates occasional reports with
 271           zero differences.
 272
 273         + modified to avoid buffer overflows.
 274
 275         + fixes for Debian #155000 (did not handle a '-' in first content-column
 276           of a unified diff) and #170947 (option to turn the progress messages
 277           off).
 278
 279         + updated configure script using aclocal.m4 macros
 280
 281         + update makefile.in to improve use of autoconf (report/patch by Nix
 282           <nix@esperi.demon.co.uk>).
 283
 284 2002-08-20 (diffstat 1.31)
 285
 286         + add -u, -k options to override diffstat's normal sorting (-u) and
 287           merging (-k) of identical filenames.  (-u requested by H Peter Anvin
 288           <hpa@zytor.com>).
 289
 290 2002-08-09 (diffstat 1.30)
 291
 292         + allow either '/' or '-' as delimiters in dates, to accommodate
 293           gendiff (report by Rik van Riel <riel@conectiva.com.br>).  This
 294           corresponds to the time format used in diffutils 2.8 whose changelog
 295           states that this is ISO 8601 (though online references differ).
 296
 297 2001-10-10 (diffstat 1.29)
 298
 299         + add bzip2 (.bz2) suffix (suggested by Gregory T Norris
 300           <haphazard@socket.net>, Debian #82969).
 301
 302         + add check for diff from RCS archive where the "diff" lines do not
 303           reference a filename.
 304
 305 2000-03-29 (diffstat 1.28)
 306
 307         + Add -c option (to prefix output with '#' comment), eliminating a step
 308           in my script that combines diffstat output with a patch.  This is a
 309           workaround for OSF1's broken sed utility.
 310
 311         + Check for compressed file suffixes .Z and .gz, read uncompressed data
 312           via pipe (Debian wishlist item #53975 by ch@lathspell.westend.com).
 313
 314         + Simplified makefile based on comments by M Sweger
 315           <mikesw@whiterose.net>
 316
 317         + Adapted changes from Troy Engel <tengel@sonic.net> as "-f" option.
 318
 319 1998-05-27 (diffstat 1.27)
 320
 321         + Debian diff's don't show dates on the lines where we expect to see
 322           filenames.
 323
 324 1998-01-16 (diffstat 1.26, Patch 5)
 325
 326         + Change copyright terms.
 327
 328         + Accommodate patches w/o tabs in header lines (e.g., from cut/paste).
 329           Still prefer the tabs because otherwise we cannot have spaces in
 330           filenames.
 331
 332         + Strip suffixes such as ".orig", to avoid confusing output.
 333
 334 1996-03-16 (diffstat 1.24, Patch 4)
 335
 336         + Corrected state-transition after "Binary".
 337
 338         + Added testing subdirectory
 339
 340         + Added -p option.
 341
 342         + Handle differences from /tmp (e.g., for X11R5 patches).
 343
 344 1995-05-06 (diffstat 1.17 Patch 3)
 345
 346         + Repost whole program to comp.sources.misc (1.17)
 347
 348         + Mods to scaling: limit to 1:1 if only a few changes were made; added
 349           logic to accumulate error across +/-/!  calls.
 350
 351         + added logic to recognize 'rcsdiff -u' output.
 352
 353 1994-12-26 (diffstat 1.15, Patch 2)
 354
 355         + Strip common pathname prefix (1.15)
 356
 357 1994-11-13 (diffstat 1.14, Patch 1)
 358
 359         + Test for <string.h> vs <strings.h>
 360
 361         + Corrected error in 'match()' that didn't handle properly the case
 362           when an argument was a null string (i.e., blank lines in a unified
 363           diff).
 364
 365         + Added options '-n' and '-V'
 366
 367         + Added patchlev.h, CHANGES files.
 368
 369         + Added install.sh, for autoconf 2.1
 370
 371 1994-06-13 (diffstat 1.12, Patch 0)
 372
 373         + Initial release of 'diffstat' (1.12).
