| 1 | Major changes in Gzip 1.3.11 (2007-02-05)
|
|---|
| 2 |
|
|---|
| 3 | * As per the GNU coding standards, the behavior of gzip and its
|
|---|
| 4 | companion executables no longer depend on the name used to invoke them.
|
|---|
| 5 | For example, 'gzip' and 'gunzip' are no longer hard links;
|
|---|
| 6 | instead, 'gunzip' is now a small program that invokes 'gzip -d'.
|
|---|
| 7 |
|
|---|
| 8 | * zdiff now checks for subsidiary gzip failures, and works around
|
|---|
| 9 | bugs in IRIX 6 sh, Tru64 4.0F ksh, and Solaris 8 bash.
|
|---|
| 10 |
|
|---|
| 11 | Major changes in Gzip 1.3.10 (2006-12-30)
|
|---|
| 12 |
|
|---|
| 13 | * gzip -c and zcat now work on special files, files with special mode bits,
|
|---|
| 14 | and files with multiple hard links.
|
|---|
| 15 | * gzip -q now exits with status 2 (not 1) when SIGPIPE is received.
|
|---|
| 16 | * zcmp and zdiff did not work in the usual case, due to a typo.
|
|---|
| 17 | * zgrep has many bugs fixed with argument handling, special characters,
|
|---|
| 18 | and exit status.
|
|---|
| 19 | * zless no longer mishandles $%=~ in file names.
|
|---|
| 20 |
|
|---|
| 21 | Gzip 1.3.9 (2006-12-15)
|
|---|
| 22 |
|
|---|
| 23 | * No major changes; only porting fixes.
|
|---|
| 24 |
|
|---|
| 25 | Major changes in Gzip 1.3.8 (2006-12-08)
|
|---|
| 26 |
|
|---|
| 27 | * Fix some gzip problems:
|
|---|
| 28 | - A security fix from Debian 1.3.5-5 was inadvertently omitted.
|
|---|
| 29 | - The assembler is now invoked with --noexecstack if supported,
|
|---|
| 30 | so that gzip can better resist stack-smashing attacks.
|
|---|
| 31 |
|
|---|
| 32 | Major changes in Gzip 1.3.7 (2006-12-06)
|
|---|
| 33 |
|
|---|
| 34 | * Fix some gzip problems:
|
|---|
| 35 | - Refuse to compress setuid or setgid files, or files with the sticky bit.
|
|---|
| 36 | - Fix more race conditions in setting file permissions and owner,
|
|---|
| 37 | removing output files, following symbolic links, and dealing with
|
|---|
| 38 | special files.
|
|---|
| 39 | - Remove most of the code working around ENAMETOOLONG deficiencies.
|
|---|
| 40 | Systems with those deficiencies are long-dead, and the workarounds
|
|---|
| 41 | had race conditions on modern hosts.
|
|---|
| 42 | - Catch CPU time and file size limit signals, too.
|
|---|
| 43 | - Check for read errors when closing files.
|
|---|
| 44 | - Fix a core dump caused by a stray abort mistakenly introduced in 1.3.6.
|
|---|
| 45 | * Fix some gzexe problems:
|
|---|
| 46 | - Improve resistance to denial-of-service attacks.
|
|---|
| 47 | - Fix some quoting and escaping bugs.
|
|---|
| 48 | - Do not assume /tmp is sticky (though it should be!).
|
|---|
| 49 | - Do not assume the working directory can be written.
|
|---|
| 50 | - Rely on PATH in the generated executable, as the man page says.
|
|---|
| 51 | - Don't assume IFS is sane.
|
|---|
| 52 | - Exit with signal's status, if signaled.
|
|---|
| 53 |
|
|---|
| 54 | Major changes in Gzip 1.3.6 (2006-11-20)
|
|---|
| 55 |
|
|---|
| 56 | * Fix some race conditions in setting file time stamps, permissions, and owner.
|
|---|
| 57 | * Fix some race conditions in signal handling.
|
|---|
| 58 | * When gzip exits due to a signal, it exits with the signal's status, not 1.
|
|---|
| 59 | * gzip now restores file time stamps to the resolution supported by the
|
|---|
| 60 | time-setting primitives of the operating system, typically 1 microsecond.
|
|---|
| 61 | Formerly it restored them only to the nearest second.
|
|---|
| 62 | * gzip -r no longer attempts to reset the last-access times of directories
|
|---|
| 63 | it reads, as this messes up when other processes are reading the directories.
|
|---|
| 64 | * The options --version and --help now work on all gzip-installed executables,
|
|---|
| 65 | and now use a format similar to other GNU programs.
|
|---|
| 66 | * The manual is now distributed under the terms of the GNU Free
|
|---|
| 67 | Documentation License without invariant sections or cover texts.
|
|---|
| 68 | * Port to current versions of Autoconf, Automake, and Gnulib.
|
|---|
| 69 |
|
|---|
| 70 | Major changes from 1.3.4 to 1.3.5
|
|---|
| 71 | * gzip now removes any output symlink before writing output file.
|
|---|
| 72 | * zgrep etc. scripts now port to POSIX 1003.1-2001 hosts.
|
|---|
| 73 | * zforce no longer assumes 14-byte file name length limit.
|
|---|
| 74 | * zless is now implemented using less and LESSOPEN, not zmore and PAGER.
|
|---|
| 75 | * assembly-language speedups reenabled; were mistakenly disabled in 1.3.
|
|---|
| 76 |
|
|---|
| 77 | Major changes from 1.3.3 to 1.3.4
|
|---|
| 78 | * Less output is lost when decompressing a truncated file.
|
|---|
| 79 | * The manual is now distributed under the terms of the GNU Free
|
|---|
| 80 | Documentation License.
|
|---|
| 81 |
|
|---|
| 82 | No major changes in 1.3.2 or 1.3.3 (bug fixes only)
|
|---|
| 83 |
|
|---|
| 84 | Major changes from 1.3 to 1.3.1
|
|---|
| 85 | * zgrep now supports --, -H, -h, -L, -l, -C, -d, -m and their long equivalents.

|
|---|
| 89 | * Adjust file size listing format for files larger than 10 GB.
|
|---|
| 90 | * New command `zless'.
|
|---|
| 91 | * `zdiff' now reports exit status like `diff' does.
|
|---|
| 92 | * `zcat' is now always called `zcat', not `gzcat'.
|
|---|
| 93 | Similarly for `zdiff', `zgrep', `zmore', `znew', `zforce'.
|
|---|
| 94 | * Warn about a compressed file's trailing zeros only if verbose,
|
|---|
| 95 | for compatibility with recent versions of GNU tar.
|
|---|
| 96 | * Conform to changes to GNU makefile standards.
|
|---|
| 97 | * Port to Autoconf 2.13.
|
|---|

|
|---|
| 99 | * Fix bugs in the following areas:
|
|---|

|
|---|
| 101 | - security hole involving symlinks from /tmp
|
|---|
| 102 | - security hole involving long file names
|
|---|
| 103 | - permissions bug when compressing a symbolic link to a file
|
|---|
| 104 | - core dumps
|
|---|

|
|---|
| 109 |
|
|---|
| 110 | Major changes from 1.2.3 to 1.2.4
|
|---|
| 111 | * By default, do not restore file name and timestamp from those saved
|
|---|
| 112 | inside the .gz file (behave as 'compress'). Added the --name option
|
|---|
| 113 | to force name and timestamp restoration.
|
|---|
| 114 | * Accept - as synonym for stdin.
|
|---|
| 115 | * Use manlinks=so or ln to support either hard links or .so in man pages
|
|---|
| 116 | * Accept foo.gz~ in zdiff.
|
|---|
| 117 | * Added support for Windows NT
|
|---|
| 118 | * Handle ENAMETOOLONG for strict Posix systems
|
|---|
| 119 | * Use --recursive instead of --recurse to comply with Webster and
|
|---|
| 120 | the GNU stdandard.
|
|---|
| 121 | * Allow installation of shell scripts with a g prefix: make G=g install
|
|---|
| 122 | * Install by default zcat as gzcat if gzcat already exists in path.
|
|---|
| 123 | * Let zmore behave as more when invoked without parameters (give help)
|
|---|
| 124 | * Let gzip --list reject files not in gzip format even with --force.
|
|---|
| 125 | * Don't complain about non gzip files for options -rt or -rl.
|
|---|
| 126 | * Added advice in INSTALL for several systems.
|
|---|
| 127 |
|
|---|
| 128 | Major changes from 1.2.2 to 1.2.3
|
|---|
| 129 | * Don't display the output name when decompressing except with --verbose.
|
|---|
| 130 | * Remove usage of alloca in getopt.c and all makefiles.
|
|---|
| 131 | * Added the zfile shell script in subdirectory sample.
|
|---|
| 132 | * Moved the list of compiler bugs from README to INSTALL.
|
|---|
| 133 | * Added vms/Readme.vms.
|
|---|
| 134 |
|
|---|
| 135 | Major changes from 1.2.1 to 1.2.2
|
|---|
| 136 | * Fix a compilation error on Sun with cc (worked with gcc).
|
|---|
| 137 |
|
|---|
| 138 | Major changes from 1.2 to 1.2.1
|
|---|
| 139 | * Let zmore act as more if the data is not gzipped.
|
|---|
| 140 | * made gzexe more secure (don't rely on PATH).
|
|---|
| 141 | * By default, display output name only when the name was actually truncated.
|
|---|
| 142 |
|
|---|
| 143 | Major changes from 1.1.2 to 1.2
|
|---|
| 144 | * Added the --list option to display the file characteristics.
|
|---|
| 145 | * Added the --no-name option: do not save or restore original filename
|
|---|
| 146 | Save the original name by default.
|
|---|
| 147 | * Allow gunzip --suffix "" to attempt decompression on any file
|
|---|
| 148 | regardless of its extension if an original name is present.
|
|---|
| 149 | * Add support for the SCO compress -H format.
|
|---|
| 150 | * gzip --fast now compresses faster (speed close to that of compress)
|
|---|
| 151 | with degraded compression ratio (but still better than compress).
|
|---|
| 152 | Default level changed to -6 (acts exactly as previous level -5) to
|
|---|
| 153 | be a better indication of its placement in the speed/ratio range.
|
|---|
| 154 | * Use smart name truncation: 123456789012.c -> 123456789.c.gz
|
|---|
| 155 | instead of 12345678901.gz
|
|---|
| 156 | * With --force, let zcat pass non gzip'ed data unchanged (zcat == cat)
|
|---|
| 157 | * Added the zgrep shell script.
|
|---|
| 158 | * Made sub.c useful for 16 bit sound, 24 bit images, etc..
|
|---|
| 159 | * Supress warnings about suffix for gunzip -r, except with --verbose.

| 160 | * On MSDOS, use .gz extension when possible (files without extension)
|
|---|
| 161 | * Moved the sample programs to a subdirectory sample.
|
|---|
| 162 | * Added a "Special targets" section in INSTALL.
|
|---|
| 163 |
|
|---|
| 164 | Major changes from 1.1.1 to 1.1.2.
|
|---|
| 165 | * Fix serious bug for VMS (-gz not removed when decompressing).
|
|---|
| 166 | * Allow suffix other than .gz in znew.
|
|---|
| 167 | * Do not display compression ratio when decompressing stdin.
|
|---|
| 168 | * In zmore.in, work around brain damaged stty -g (Ultrix).
|
|---|
| 169 | * Display a correct compression ratio for .Z files.
|
|---|
| 170 | * Added .z to .gz renaming script in INTALL.
|
|---|
| 171 | * Allow setting CFLAGS in configure.
|
|---|
| 172 |
|
|---|
| 173 | Major changes from 1.1 to 1.1.1.

|---|
| 175 | * Added --ascii option.
|
|---|
| 176 | * Add workaround in configure.in for Ultrix (quote eval argument)
|
|---|
| 177 |
|
|---|
| 178 | Major changes from 1.0.7 to 1.1.
|
|---|
| 179 | * Use .gz suffix by default, add --suffix option.
|
|---|
| 180 | * Let gunzip accept a "_z" suffix (used by one 'compress' on Vax/VMS).
|
|---|
| 181 | * Quit when reading garbage from stdin instead of reporting an error.
|
|---|
| 182 | * Added makefile for VAX/MMS and support for wildcards on VMS.
|
|---|
| 183 | * Added support for MSC under OS/2.
|
|---|
| 184 | * Added support for Prime/PRIMOS.
|
|---|
| 185 | * Display compression ratio also when decompressing (with --verbose).
|
|---|
| 186 | * Quit after --version (GNU standard)
|
|---|
| 187 | * Use --force to bypass isatty() check
|
|---|

|---|
| 189 | * Added comparison of zip and gzip in the readme file.
|
|---|
| 190 | * Added small sample programs (ztouch, sub, add)
|
|---|
| 191 | * Use less memory when compiled with -DSMALL_MEM (for MSDOS).
|
|---|
| 192 | * Remove the "off by more than one minute" time stamp kludge
|
|---|
| 193 |
|
|---|
| 194 | Major changes from 1.0.6 to 1.0.7.
|
|---|
| 195 | * Allow zmore to read from standard input (like more).
|
|---|
| 196 | * Support the 68000 (Atari ST) in match.S.
|
|---|
| 197 | * Retry partial writes (required on Linux when gzip is suspended in a pipe).
|
|---|
| 198 | * Allow full pathnames and renamings in gzexe.
|
|---|
| 199 | * Don't let gzexe compress setuid executables or gzip itself.
|
|---|
| 200 | * Added vms/Makefile.gcc for gcc on the Vax.
|
|---|
| 201 | * Allow installation of binaries and shell scripts in different dirs.
|
|---|
| 202 | * Allows complex PAGER variable in zmore (e.g.: PAGER="col -x | more")
|
|---|
| 203 | * Allow installation of zcat as gzcat.
|
|---|
| 204 | * Several small changes for portability to old or weird systems.

|
|---|
| 206 | gzip is invoked without parameters and without redirection.
|
|---|
| 207 | * Add compile option GNU_STANDARD to respect the GNU coding standards:
|
|---|
| 208 | with -DGNU_STANDARD, behave as gzip even if invoked under the name gunzip.
|
|---|
| 209 | (I don't like the last two changes, which were requested by the FSF.)
|
|---|
| 210 |
|
|---|
| 211 | Major changes from 1.0.5 to 1.0.6.
|
|---|
| 212 | * Let gzexe detect executables that are already gzexe'd.
|
|---|
| 213 | * Keep file attributes in znew and gzexe if cpmod is available.
|
|---|
| 214 | * Don't try restoring record format on VMS (1.0.5 did not work correctly)
|
|---|
| 215 | * Added asm version for 68000 in amiga/match.a.
|
|---|
| 216 | Use asm version for Atari TT and NeXT.
|
|---|
| 217 | * For OS/2, assume HPFS by default, add flag OS2FAT if necessary.
|
|---|
| 218 | * Fixed some bugs in zdiff and define zcmp as a link to zdiff.
|
|---|
| 219 |
|
|---|
| 220 |
|
|---|
| 221 | Major changes from 1.0.4 to 1.0.5.
|
|---|
| 222 | * For VMS, restore the file type for variable record format, otherwise
|
|---|
| 223 | extract in fixed length format (not perfect, but better than
|
|---|
| 224 | forcing all files to be in stream_LF format).
|
|---|
| 225 | * For VMS, use "-z" default suffix and accept a version number in file names.
|
|---|
| 226 | * For Unix, allow compression of files with name ending in 'z'. Use only
|
|---|
| 227 | .z, .*-z, .tgz, .taz as valid gzip extensions. In the last two cases,
|
|---|
| 228 | extract to .tar by default.
|
|---|
| 229 | * On some versions of MSDOS, files with a 3 character extension could not
|
|---|
| 230 | be compressed.
|
|---|
| 231 | * Garbage collect files in /tmp created by gzexe.
|
|---|
| 232 | * Fix the 'OS code' byte in the gzip header.
|
|---|
| 233 | * For the Amiga, add the missing utime.h and add support for gcc.
|
|---|
| 234 |
|
|---|
| 235 |
|
|---|
| 236 | Major changes from 1.0.3 to 1.0.4.
|
|---|
| 237 | * Added optimized asm version for 68020.
|
|---|
| 238 | * Add support for DJGPP.
|
|---|
| 239 |
|
|---|
| 240 | * Add support for the Atari ST.
|
|---|
| 241 | * Added zforce to rename gzip'ed files with truncated names.
|
|---|
| 242 | * Do not install with name uncompress (some systems rely on the
|
|---|
| 243 | absence of any check in the old uncompress).
|
|---|
| 244 | * Added missing function (fcfree) in msdos/tailor.c
|
|---|
| 245 | * Let gunzip handle .tgz files, and let gzip skip them.
|
|---|
| 246 | * Added -d option (decompress) for gzexe and try preserving file permissions.
|
|---|
| 247 | * Suppress all warnings with -q.
|
|---|
| 248 | * Use GZIP_OPT for VMS to avoid conflict with program name.
|
|---|
| 249 | * ... and many other small changes (see ChangeLog)
|
|---|
| 250 |
|
|---|
| 251 |
|
|---|
| 252 | Major changes from 1.0.2 to 1.0.3
|
|---|
| 253 | * Added -K option for znew to keep old .Z files if smaller
|
|---|
| 254 | * Added -q option (quiet) to cancel -v in GZIP env variable.
|
|---|
| 255 | * Made gzexe safer on systems with filename limitation to 14 chars.
|
|---|
| 256 | * Fixed bugs in handling of GZIP env variable and incorrect free with Turbo C.
|
|---|
| 257 |
|
|---|
| 258 |
|
|---|
| 259 | Major changes from 1.0.1 to 1.0.2
|
|---|
| 260 | * Added env variable GZIP for default options. Example:
|
|---|
| 261 | for sh: GZIP="-8 -v"; export GZIP
|
|---|
| 262 | for csh: setenv GZIP "-8 -v"
|
|---|
| 263 | * Added support for the Amiga.
|
|---|
| 264 | * znew now keeps the old .Z if it is smaller than the .z file.
|
|---|
| 265 | This can happen for some large and very redundant files.
|
|---|
| 266 | * Do not complain about trailing garbage for record oriented IO (Vax/VMS).
|
|---|
| 267 | This implies however that multi-part gzip files are not supported
|
|---|
| 268 | on such systems.
|
|---|
| 269 | * Added gzexe to compress rarely used executables.
|
|---|
| 270 | * Reduce memory usage (required for MSDOS and useful on all systems).
|
|---|
| 271 | * Preserve time stamp in znew -P (pipe option) if touch -r works.
|
|---|
| 272 |
|
|---|
| 273 |
|
|---|
| 274 | Major changes from 1.0 to 1.0.1
|
|---|
| 275 | * fix trivial errors in the Borland makefile (msdos/Makefile.bor)
|
|---|
| 276 |
|
|---|
| 277 |
|
|---|
| 278 | Major changes from 0.8.2 to 1.0
|
|---|
| 279 | * gzip now runs on Vax/VMS
|
|---|
| 280 | * gzip will not not overwrite files without -f when using /bin/sh in
|
|---|
| 281 | background.
|
|---|
| 282 | * Support the test option -t for compressed (.Z) files.
|
|---|
| 283 | Allow some data recovery for bad .Z files.
|
|---|
| 284 | * Added makefiles for MSDOS (Only tested for MSC, not Borland).
|
|---|
| 285 | * still more changes to configure for several systems
|
|---|
| 286 |
|
|---|
| 287 |
|
|---|
| 288 | Major changes from 0.8.1 to 0.8.2:
|
|---|
| 289 | * yet more changes to configure for Linux and other systems
|
|---|
| 290 | * Allow zcat on a file with multiple links.
|
|---|
| 291 |
|
|---|
| 292 |
|
|---|
| 293 | Major changes from 0.8 to 0.8.1:
|
|---|
| 294 | * znew has now a pipe option -P to reduce the disk space requirements,
|
|---|
| 295 | but this option does not preserve timestamps.
|
|---|
| 296 | * Fixed some #if directives for compilation with TurboC.
|
|---|
| 297 |
|
|---|
| 298 |
|
|---|
| 299 | Major changes from 0.7 to 0.8:
|
|---|
| 300 | * gzip can now extract .z files created by 'pack'.
|
|---|
| 301 | * configure should no longer believe that every machine is a 386
|
|---|
| 302 | * Fix the entry for /etc/magic in INSTALL.
|
|---|
| 303 | * Add patch for GNU tar 1.11.1 and a pointer to crypt++.el
|
|---|
| 304 | * Uncompress files with multiple links only with -f.
|
|---|
| 305 | * Fix for uncompress of .Z files on 16-bit machines
|
|---|
| 306 | * Create a correct output name for file names of exactly N-1 chars when
|
|---|
| 307 | the system has a limit of N chars.
|
|---|
| 308 |
|
|---|
| 309 |

| 310 | Major changes from 0.6 to 0.7:
|
|---|
| 311 | * Use "make check" instead of "make test".
|
|---|
| 312 | * Keep time stamp and pass options to gzip in znew.
|
|---|
| 313 | * Do not create .z.z files with gzip -r.
|
|---|
| 314 | * Allow again gunzip .zip files (was working in 0.5)
|
|---|
| 315 | * Allow again compilation with TurboC 2.0 (was working in 0.4)

| 317 |
|
|---|
| 318 | Major changes form 0.5 to 0.6:
|
|---|
| 319 | * gunzip reported an error when extracting certain .z files. The .z files
|
|---|
| 320 | produced by gzip 0.5 are correct and can be read by gunzip 0.6.
|
|---|
| 321 | * gunzip now supports multiple compressed members within a single .z file.
|
|---|
| 322 | * Fix the check for i386 in configure.
|
|---|
| 323 | * Added "make test" to check for compiler bugs. (gcc -finline-functions
|
|---|
| 324 | is broken at least on the NeXT.)
|
|---|
| 325 | * Use environment variable PAGER in zmore if it is defined.
|
|---|
| 326 | * Accept gzcat in addition to zcat for people having /usr/bin before
