|
jpayne@68
|
5 5.6.4 (2025-01-23)
|
|
jpayne@68
|
6
|
|
jpayne@68
|
7 * liblzma: Fix LZMA/LZMA2 encoder on big endian ARM64.
|
|
jpayne@68
|
8
|
|
jpayne@68
|
9 * xz:
|
|
jpayne@68
|
10
|
|
jpayne@68
|
11 - Fix --filters= and --filters1= ... --filters9= options
|
|
jpayne@68
|
12 parsing. They require an argument, thus "xz --filters lzma2"
|
|
jpayne@68
|
13 should work in addition to "xz --filters=lzma2".
|
|
jpayne@68
|
14
|
|
jpayne@68
|
15 - On the man page, note in the --compress and --decompress
|
|
jpayne@68
|
16 options that the default behavior is to delete the input
|
|
jpayne@68
|
17 file unless writing to standard output. It was already
|
|
jpayne@68
|
18 documented in the DESCRIPTION section but new users in
|
|
jpayne@68
|
19 a hurry might miss it.
|
|
jpayne@68
|
20
|
|
jpayne@68
|
21 * Windows (native builds, not Cygwin): Fix regressions introduced
|
|
jpayne@68
|
22 in XZ Utils 5.6.3 which caused non-ASCII characters to display
|
|
jpayne@68
|
23 incorrectly. Only builds with translation support were affected
|
|
jpayne@68
|
24 (--enable-nls or ENABLE_NLS=ON). The following changes affect
|
|
jpayne@68
|
25 builds that have translations enabled:
|
|
jpayne@68
|
26
|
|
jpayne@68
|
27 - Require UCRT because MSVCRT doesn't support UTF-8
|
|
jpayne@68
|
28 locales and thus translations won't be readable on
|
|
jpayne@68
|
29 Windows 10 version 1903 and later. (MSVCRT builds
|
|
jpayne@68
|
30 are still possible with --disable-nls or ENABLE_NLS=OFF.)
|
|
jpayne@68
|
31
|
|
jpayne@68
|
32 - Require gettext-runtime >= 0.23.1 because older versions
|
|
jpayne@68
|
33 don't autodetect the use of the UTF-8 code page. This
|
|
jpayne@68
|
34 resulted in garbled non-ASCII characters even with UCRT.
|
|
jpayne@68
|
35
|
|
jpayne@68
|
36 - Partially fix alignment issues in xz --verbose --list
|
|
jpayne@68
|
37 with translated messages. Chinese (simplified),
|
|
jpayne@68
|
38 Chinese (traditional), and Korean column headings
|
|
jpayne@68
|
39 are misaligned still because Windows and MinGW-w64
|
|
jpayne@68
|
40 don't provide wcwidth() and XZ Utils doesn't include
|
|
jpayne@68
|
41 a replacement function either.
|
|
jpayne@68
|
42
|
|
jpayne@68
|
43 * CMake: Explicitly disable unity builds. This prevents build
|
|
jpayne@68
|
44 failures when another project uses XZ Utils via CMake's
|
|
jpayne@68
|
45 FetchContent module, and that project enables unity builds.
|
|
jpayne@68
|
46
|
|
jpayne@68
|
47 * Update Chinese (traditional) and Serbian translations.
|
|
jpayne@68
|
48
|
|
jpayne@68
|
49
|
|
jpayne@68
|
50 5.6.3 (2024-10-01)
|
|
jpayne@68
|
51
|
|
jpayne@68
|
52 IMPORTANT: This includes a Windows-specific security fix to
|
|
jpayne@68
|
53 the command line tools (CVE-2024-47611). liblzma isn't affected
|
|
jpayne@68
|
54 by this issue.
|
|
jpayne@68
|
55
|
|
jpayne@68
|
56 * liblzma:
|
|
jpayne@68
|
57
|
|
jpayne@68
|
58 - Fix x86-64 inline assembly compatibility with GNU Binutils
|
|
jpayne@68
|
59 older than 2.27.
|
|
jpayne@68
|
60
|
|
jpayne@68
|
61 - Fix the build with GCC 4.2 on OpenBSD/sparc64.
|
|
jpayne@68
|
62
|
|
jpayne@68
|
63 * xzdec: Display an error instead of failing silently if the
|
|
jpayne@68
|
64 unsupported option -M is specified.
|
|
jpayne@68
|
65
|
|
jpayne@68
|
66 * lzmainfo: Fix integer overflows when rounding the dictionary and
|
|
jpayne@68
|
67 uncompressed sizes to the nearest mebibyte.
|
|
jpayne@68
|
68
|
|
jpayne@68
|
69 * Windows (except Cygwin and MSYS2): Add an application manifest to
|
|
jpayne@68
|
70 xz, xzdec, lzmadec, and lzmainfo executables:
|
|
jpayne@68
|
71
|
|
jpayne@68
|
72 - Declare them compatible with Vista/7/8/8.1/10/11. This way
|
|
jpayne@68
|
73 the programs won't needlessly use Operating System Context
|
|
jpayne@68
|
74 of Vista when running on later Windows versions. This setting
|
|
jpayne@68
|
75 doesn't mean that the executables cannot run on even older
|
|
jpayne@68
|
76 versions if otherwise built that way.
|
|
jpayne@68
|
77
|
|
jpayne@68
|
78 - Declare them as UAC-compliant. MSVC added this by default
|
|
jpayne@68
|
79 already but it wasn't done with MinGW-w64, at least not
|
|
jpayne@68
|
80 with all toolchain variants.
|
|
jpayne@68
|
81
|
|
jpayne@68
|
82 - Declare them long path aware. This makes long path names
|
|
jpayne@68
|
83 work on Windows 10 and 11 if the feature has been enabled
|
|
jpayne@68
|
84 in the Windows registry.
|
|
jpayne@68
|
85
|
|
jpayne@68
|
86 - Use the UTF-8 code page on Windows 10 version 1903 and later.
|
|
jpayne@68
|
87
|
|
jpayne@68
|
88 * Now command line tools can access files whose names
|
|
jpayne@68
|
89 contain characters that don't exist in the current
|
|
jpayne@68
|
90 legacy code page.
|
|
jpayne@68
|
91
|
|
jpayne@68
|
92 * The options --files and --files0 now expect file lists
|
|
jpayne@68
|
93 to be in UTF-8 instead of the legacy code page.
|
|
jpayne@68
|
94
|
|
jpayne@68
|
95 * This fixes a security issue: If a command line contains
|
|
jpayne@68
|
96 Unicode characters (for example, filenames) that don't
|
|
jpayne@68
|
97 exist in the current legacy code page, the characters are
|
|
jpayne@68
|
98 converted to similar-looking characters with best-fit
|
|
jpayne@68
|
99 mapping. Some best-fit mappings result in ASCII
|
|
jpayne@68
|
100 characters that change the meaning of the command line,
|
|
jpayne@68
|
101 which can be exploited with malicious filenames to do
|
|
jpayne@68
|
102 argument injection or directory traversal attacks.
|
|
jpayne@68
|
103 UTF-8 avoids best-fit mappings and thus fixes the issue.
|
|
jpayne@68
|
104 (CVE-2024-47611)
|
|
jpayne@68
|
105
|
|
jpayne@68
|
106 Forcing the process code page to UTF-8 is possible only
|
|
jpayne@68
|
107 on Windows 10 version 1903 and later. The command line
|
|
jpayne@68
|
108 tools remain vulnerable if used on an old older
|
|
jpayne@68
|
109 version of Windows.
|
|
jpayne@68
|
110
|
|
jpayne@68
|
111 This issue was discovered by Orange Tsai and splitline
|
|
jpayne@68
|
112 from DEVCORE Research Team.
|
|
jpayne@68
|
113
|
|
jpayne@68
|
114 A related smaller issue remains: Windows filenames may
|
|
jpayne@68
|
115 contain unpaired surrogates (invalid UTF-16). These are
|
|
jpayne@68
|
116 converted to the replacement character U+FFFD in the
|
|
jpayne@68
|
117 UTF-8 code page. Thus, filenames with different unpaired
|
|
jpayne@68
|
118 surrogates appear identical and aren't distinguishable
|
|
jpayne@68
|
119 from filenames that contain the actual replacement
|
|
jpayne@68
|
120 character U+FFFD.
|
|
jpayne@68
|
121
|
|
jpayne@68
|
122 * When building with MinGW-w64, it is recommended to use
|
|
jpayne@68
|
123 UCRT version instead of the old MSVCRT. For example,
|
|
jpayne@68
|
124 non-ASCII characters from filenames won't print
|
|
jpayne@68
|
125 correctly in messages to console with MSVCRT with
|
|
jpayne@68
|
126 the UTF-8 code page (a cosmetic issue). liblzma-only
|
|
jpayne@68
|
127 builds are still fine with MSVCRT.
|
|
jpayne@68
|
128
|
|
jpayne@68
|
129 - Cygwin and MSYS2 process command line options differently and
|
|
jpayne@68
|
130 the above issues don't exist. There is no need to replace the
|
|
jpayne@68
|
131 default application manifest on Cygwin and MSYS2.
|
|
jpayne@68
|
132
|
|
jpayne@68
|
133 * Autotools-based build:
|
|
jpayne@68
|
134
|
|
jpayne@68
|
135 - Fix feature checks with link-time optimization (-flto).
|
|
jpayne@68
|
136
|
|
jpayne@68
|
137 - Solaris: Fix a compatibility issue in version.sh. It matters
|
|
jpayne@68
|
138 if one wants to regenerate configure by running autoconf.
|
|
jpayne@68
|
139
|
|
jpayne@68
|
140 * CMake:
|
|
jpayne@68
|
141
|
|
jpayne@68
|
142 - Use paths relative to ${prefix} in liblzma.pc when possible.
|
|
jpayne@68
|
143 This is done only with CMake >= 3.20.
|
|
jpayne@68
|
144
|
|
jpayne@68
|
145 - MSVC: Install liblzma.pc as it can be useful with MSVC too.
|
|
jpayne@68
|
146
|
|
jpayne@68
|
147 - Windows: Fix liblzma filename prefix, for example:
|
|
jpayne@68
|
148
|
|
jpayne@68
|
149 * Cygwin: The DLL was incorrectly named liblzma-5.dll.
|
|
jpayne@68
|
150 Now it is cyglzma-5.dll.
|
|
jpayne@68
|
151
|
|
jpayne@68
|
152 * MSVC: Rename import library from liblzma.lib to lzma.lib
|
|
jpayne@68
|
153 while keeping liblzma.dll name as is. This helps with
|
|
jpayne@68
|
154 "pkgconf --msvc-syntax --libs liblzma" because it mungles
|
|
jpayne@68
|
155 "-llzma" in liblzma.pc to "lzma.lib".
|
|
jpayne@68
|
156
|
|
jpayne@68
|
157 * MinGW-w64: No changes.
|
|
jpayne@68
|
158
|
|
jpayne@68
|
159 - Windows: Use the correct resource file for lzmadec.exe.
|
|
jpayne@68
|
160 Previously the resource file for xzdec.exe was used for both.
|
|
jpayne@68
|
161 Autotools-based build isn't affected.
|
|
jpayne@68
|
162
|
|
jpayne@68
|
163 - Prefer a C11 compiler over a C99 compiler but accept both.
|
|
jpayne@68
|
164
|
|
jpayne@68
|
165 - Link Threads::Threads against liblzma using PRIVATE so that
|
|
jpayne@68
|
166 -pthread and such flags won't unnecessarily get included in
|
|
jpayne@68
|
167 the usage requirements of shared liblzma. That is,
|
|
jpayne@68
|
168 target_link_libraries(foo PRIVATE liblzma::liblzma) no
|
|
jpayne@68
|
169 longer adds -pthread if using POSIX threads and linking
|
|
jpayne@68
|
170 against shared liblzma. The threading flags are still added
|
|
jpayne@68
|
171 if linking against static liblzma.
|
|
jpayne@68
|
172
|
|
jpayne@68
|
173 * Updated translations: Catalan, Chinese (simplified), and
|
|
jpayne@68
|
174 Brazilian Portuguese.
|
|
jpayne@68
|
175
|
|
jpayne@68
|
176
|
|
jpayne@68
|
177 5.6.2 (2024-05-29)
|
|
jpayne@68
|
178
|
|
jpayne@68
|
179 * Remove the backdoor (CVE-2024-3094).
|
|
jpayne@68
|
180
|
|
jpayne@68
|
181 * Not changed: Memory sanitizer (MSAN) has a false positive
|
|
jpayne@68
|
182 in the CRC CLMUL code which also makes OSS Fuzz unhappy.
|
|
jpayne@68
|
183 Valgrind is smarter and doesn't complain.
|
|
jpayne@68
|
184
|
|
jpayne@68
|
185 A revision to the CLMUL code is coming anyway and this issue
|
|
jpayne@68
|
186 will be cleaned up as part of it. It won't be backported to
|
|
jpayne@68
|
187 5.6.x or 5.4.x because the old code isn't wrong. There is
|
|
jpayne@68
|
188 no reason to risk introducing regressions in old branches
|
|
jpayne@68
|
189 just to silence a false positive.
|
|
jpayne@68
|
190
|
|
jpayne@68
|
191 * liblzma:
|
|
jpayne@68
|
192
|
|
jpayne@68
|
193 - lzma_index_decoder() and lzma_index_buffer_decode(): Fix
|
|
jpayne@68
|
194 a missing output pointer initialization (*i = NULL) if the
|
|
jpayne@68
|
195 functions are called with invalid arguments. The API docs
|
|
jpayne@68
|
196 say that such an initialization is always done. In practice
|
|
jpayne@68
|
197 this matters very little because the problem can only occur
|
|
jpayne@68
|
198 if the calling application has a bug and these functions
|
|
jpayne@68
|
199 return LZMA_PROG_ERROR.
|
|
jpayne@68
|
200
|
|
jpayne@68
|
201 - lzma_str_to_filters(): Fix a missing output pointer
|
|
jpayne@68
|
202 initialization (*error_pos = 0). This is very similar
|
|
jpayne@68
|
203 to the fix above.
|
|
jpayne@68
|
204
|
|
jpayne@68
|
205 - Fix C standard conformance with function pointer types.
|
|
jpayne@68
|
206
|
|
jpayne@68
|
207 - Remove GNU indirect function (IFUNC) support. This is *NOT*
|
|
jpayne@68
|
208 done for security reasons even though the backdoor relied on
|
|
jpayne@68
|
209 this code. The performance benefits of IFUNC are too tiny in
|
|
jpayne@68
|
210 this project to make the extra complexity worth it.
|
|
jpayne@68
|
211
|
|
jpayne@68
|
212 - FreeBSD on ARM64: Add error checking to CRC32 instruction
|
|
jpayne@68
|
213 support detection.
|
|
jpayne@68
|
214
|
|
jpayne@68
|
215 - Fix building with NVIDIA HPC SDK.
|
|
jpayne@68
|
216
|
|
jpayne@68
|
217 * xz:
|
|
jpayne@68
|
218
|
|
jpayne@68
|
219 - Fix a C standard conformance issue in --block-list parsing
|
|
jpayne@68
|
220 (arithmetic on a null pointer).
|
|
jpayne@68
|
221
|
|
jpayne@68
|
222 - Fix a warning from GNU groff when processing the man page:
|
|
jpayne@68
|
223 "warning: cannot select font 'CW'"
|
|
jpayne@68
|
224
|
|
jpayne@68
|
225 * xzdec: Add support for Linux Landlock ABI version 4. xz already
|
|
jpayne@68
|
226 had the v3-to-v4 change but it had been forgotten from xzdec.
|
|
jpayne@68
|
227
|
|
jpayne@68
|
228 * Autotools-based build system (configure):
|
|
jpayne@68
|
229
|
|
jpayne@68
|
230 - Symbol versioning variant can now be overridden with
|
|
jpayne@68
|
231 --enable-symbol-versions. Documentation in INSTALL was
|
|
jpayne@68
|
232 updated to match.
|
|
jpayne@68
|
233
|
|
jpayne@68
|
234 - Add new configure option --enable-doxygen to enable
|
|
jpayne@68
|
235 generation and installation of the liblzma API documentation
|
|
jpayne@68
|
236 using Doxygen. Documentation in INSTALL and PACKAGERS was
|
|
jpayne@68
|
237 updated to match.
|
|
jpayne@68
|
238
|
|
jpayne@68
|
239 CMake:
|
|
jpayne@68
|
240
|
|
jpayne@68
|
241 - Fix detection of Linux Landlock support. The detection code
|
|
jpayne@68
|
242 in CMakeLists.txt had been sabotaged.
|
|
jpayne@68
|
243
|
|
jpayne@68
|
244 - Disable symbol versioning on non-glibc Linux to match what
|
|
jpayne@68
|
245 the Autotools build does. For example, symbol versioning
|
|
jpayne@68
|
246 isn't enabled with musl.
|
|
jpayne@68
|
247
|
|
jpayne@68
|
248 - Symbol versioning variant can now be overridden by setting
|
|
jpayne@68
|
249 SYMBOL_VERSIONING to "OFF", "generic", or "linux".
|
|
jpayne@68
|
250
|
|
jpayne@68
|
251 - Add support for all tests in typical build configurations.
|
|
jpayne@68
|
252 Now the only difference to the tests coverage to Autotools
|
|
jpayne@68
|
253 is that CMake-based build will skip more tests if features
|
|
jpayne@68
|
254 are disabled. Such builds are only for special cases like
|
|
jpayne@68
|
255 embedded systems.
|
|
jpayne@68
|
256
|
|
jpayne@68
|
257 - Separate the CMake code for the tests into tests/tests.cmake.
|
|
jpayne@68
|
258 It is used conditionally, thus it is possible to
|
|
jpayne@68
|
259
|
|
jpayne@68
|
260 rm -rf tests
|
|
jpayne@68
|
261
|
|
jpayne@68
|
262 and the CMake-based build will still work normally except
|
|
jpayne@68
|
263 that no tests are then available.
|
|
jpayne@68
|
264
|
|
jpayne@68
|
265 - Add a option ENABLE_DOXYGEN to enable generation and
|
|
jpayne@68
|
266 installation of the liblzma API documentation using Doxygen.
|
|
jpayne@68
|
267
|
|
jpayne@68
|
268 * Documentation:
|
|
jpayne@68
|
269
|
|
jpayne@68
|
270 - Omit the Doxygen-generated liblzma API documentation from the
|
|
jpayne@68
|
271 package. Instead, the generation and installation of the API
|
|
jpayne@68
|
272 docs can be enabled with a configure or CMake option if
|
|
jpayne@68
|
273 Doxygen is available.
|
|
jpayne@68
|
274
|
|
jpayne@68
|
275 - Remove the XZ logo which was used in the API documentation.
|
|
jpayne@68
|
276 The logo has been retired and isn't used by the project
|
|
jpayne@68
|
277 anymore. However, it's OK to use it in contexts that refer
|
|
jpayne@68
|
278 to the backdoor incident.
|
|
jpayne@68
|
279
|
|
jpayne@68
|
280 - Remove the PDF versions of the man pages from the source
|
|
jpayne@68
|
281 package. These existed primarily for users of operating
|
|
jpayne@68
|
282 systems which don't come with tools to render man page
|
|
jpayne@68
|
283 source files. The plain text versions are still included
|
|
jpayne@68
|
284 in doc/man/txt. PDF files can still be generated to doc/man,
|
|
jpayne@68
|
285 if the required tools are available, using "make pdf" after
|
|
jpayne@68
|
286 running "configure".
|
|
jpayne@68
|
287
|
|
jpayne@68
|
288 - Update home page URLs back to their old locations on
|
|
jpayne@68
|
289 tukaani.org.
|
|
jpayne@68
|
290
|
|
jpayne@68
|
291 - Update maintainer info.
|
|
jpayne@68
|
292
|
|
jpayne@68
|
293 * Tests:
|
|
jpayne@68
|
294
|
|
jpayne@68
|
295 - In tests/files/README, explain how to recreate the ARM64
|
|
jpayne@68
|
296 test files.
|
|
jpayne@68
|
297
|
|
jpayne@68
|
298 - Remove two tests that used tiny x86 and SPARC object files
|
|
jpayne@68
|
299 as the input files. The matching .c file was included but
|
|
jpayne@68
|
300 the object files aren't easy to reproduce. The test cases
|
|
jpayne@68
|
301 weren't great anyway; they were from the early days (2009)
|
|
jpayne@68
|
302 of the project when the test suite had very few tests.
|
|
jpayne@68
|
303
|
|
jpayne@68
|
304 - Improve a few tests.
|
|
jpayne@68
|
305
|
|
jpayne@68
|
306
|
|
jpayne@68
|
307 5.6.1 (2024-03-09)
|
|
jpayne@68
|
308
|
|
jpayne@68
|
309 IMPORTANT: This fixed bugs in the backdoor (CVE-2024-3094) (someone
|
|
jpayne@68
|
310 had forgot to run Valgrind).
|
|
jpayne@68
|
311
|
|
jpayne@68
|
312 * liblzma: Fixed two bugs relating to GNU indirect function (IFUNC)
|
|
jpayne@68
|
313 with GCC. The more serious bug caused a program linked with
|
|
jpayne@68
|
314 liblzma to crash on start up if the flag -fprofile-generate was
|
|
jpayne@68
|
315 used to build liblzma. The second bug caused liblzma to falsely
|
|
jpayne@68
|
316 report an invalid write to Valgrind when loading liblzma.
|
|
jpayne@68
|
317
|
|
jpayne@68
|
318 * xz: Changed the messages for thread reduction due to memory
|
|
jpayne@68
|
319 constraints to only appear under the highest verbosity level.
|
|
jpayne@68
|
320
|
|
jpayne@68
|
321 * Build:
|
|
jpayne@68
|
322
|
|
jpayne@68
|
323 - Fixed a build issue when the header file <linux/landlock.h>
|
|
jpayne@68
|
324 was present on the system but the Landlock system calls were
|
|
jpayne@68
|
325 not defined in <sys/syscall.h>.
|
|
jpayne@68
|
326
|
|
jpayne@68
|
327 - The CMake build now warns and disables NLS if both gettext
|
|
jpayne@68
|
328 tools and pre-created .gmo files are missing. Previously,
|
|
jpayne@68
|
329 this caused the CMake build to fail.
|
|
jpayne@68
|
330
|
|
jpayne@68
|
331 * Minor improvements to man pages.
|
|
jpayne@68
|
332
|
|
jpayne@68
|
333 * Minor improvements to tests.
|
|
jpayne@68
|
334
|
|
jpayne@68
|
335
|
|
jpayne@68
|
336 5.6.0 (2024-02-24)
|
|
jpayne@68
|
337
|
|
jpayne@68
|
338 IMPORTANT: This added a backdoor (CVE-2024-3094). It's enabled only
|
|
jpayne@68
|
339 in the release tarballs.
|
|
jpayne@68
|
340
|
|
jpayne@68
|
341 This bumps the minor version of liblzma because new features were
|
|
jpayne@68
|
342 added. The API and ABI are still backward compatible with liblzma
|
|
jpayne@68
|
343 5.4.x and 5.2.x and 5.0.x.
|
|
jpayne@68
|
344
|
|
jpayne@68
|
345 NOTE: As described in the NEWS for 5.5.2beta, the core components
|
|
jpayne@68
|
346 are now under the BSD Zero Clause License (0BSD).
|
|
jpayne@68
|
347
|
|
jpayne@68
|
348 Since 5.5.2beta:
|
|
jpayne@68
|
349
|
|
jpayne@68
|
350 * liblzma:
|
|
jpayne@68
|
351
|
|
jpayne@68
|
352 - Disabled the branchless C variant in the LZMA decoder based
|
|
jpayne@68
|
353 on the benchmark results from the community.
|
|
jpayne@68
|
354
|
|
jpayne@68
|
355 - Disabled x86-64 inline assembly on x32 to fix the build.
|
|
jpayne@68
|
356
|
|
jpayne@68
|
357 * Sandboxing support in xz:
|
|
jpayne@68
|
358
|
|
jpayne@68
|
359 - Landlock is now used even when xz needs to create files.
|
|
jpayne@68
|
360 In this case the sandbox has to be more permissive than
|
|
jpayne@68
|
361 when no files need to be created. A similar thing was
|
|
jpayne@68
|
362 already in use with pledge(2) since 5.3.4alpha.
|
|
jpayne@68
|
363
|
|
jpayne@68
|
364 - Landlock and pledge(2) are now stricter when reading from
|
|
jpayne@68
|
365 more than one input file and only writing to standard output.
|
|
jpayne@68
|
366
|
|
jpayne@68
|
367 - Added support for Landlock ABI version 4.
|
|
jpayne@68
|
368
|
|
jpayne@68
|
369 * CMake:
|
|
jpayne@68
|
370
|
|
jpayne@68
|
371 - Default to -O2 instead of -O3 with CMAKE_BUILD_TYPE=Release.
|
|
jpayne@68
|
372 -O3 is not useful for speed and makes the code larger.
|
|
jpayne@68
|
373
|
|
jpayne@68
|
374 - Now builds lzmainfo and lzmadec.
|
|
jpayne@68
|
375
|
|
jpayne@68
|
376 - xzdiff, xzgrep, xzless, xzmore, and their symlinks are now
|
|
jpayne@68
|
377 installed. The scripts are also tested during "make test".
|
|
jpayne@68
|
378
|
|
jpayne@68
|
379 - Added translation support for xz, lzmainfo, and the
|
|
jpayne@68
|
380 man pages.
|
|
jpayne@68
|
381
|
|
jpayne@68
|
382 - Applied the symbol versioning workaround for MicroBlaze that
|
|
jpayne@68
|
383 is used in the Autotools build.
|
|
jpayne@68
|
384
|
|
jpayne@68
|
385 - The general XZ Utils and liblzma API documentation is now
|
|
jpayne@68
|
386 installed.
|
|
jpayne@68
|
387
|
|
jpayne@68
|
388 - The CMake component names were changed a little and several
|
|
jpayne@68
|
389 were added. liblzma_Runtime and liblzma_Development are
|
|
jpayne@68
|
390 unchanged.
|
|
jpayne@68
|
391
|
|
jpayne@68
|
392 - Minimum required CMake version is now 3.14. However,
|
|
jpayne@68
|
393 translation support is disabled with CMake versions
|
|
jpayne@68
|
394 older than 3.20.
|
|
jpayne@68
|
395
|
|
jpayne@68
|
396 - The CMake-based build is now close to feature parity with the
|
|
jpayne@68
|
397 Autotools-based build. Most importantly a few tests aren't
|
|
jpayne@68
|
398 run yet. Testing the CMake-based build on different operating
|
|
jpayne@68
|
399 systems would be welcome now. See the comment at the top of
|
|
jpayne@68
|
400 CMakeLists.txt.
|
|
jpayne@68
|
401
|
|
jpayne@68
|
402 * Fixed a bug in the Autotools feature test for ARM64 CRC32
|
|
jpayne@68
|
403 instruction support for old versions of Clang. This did not
|
|
jpayne@68
|
404 affect the CMake build.
|
|
jpayne@68
|
405
|
|
jpayne@68
|
406 * Windows:
|
|
jpayne@68
|
407
|
|
jpayne@68
|
408 - The build instructions in INSTALL and windows/INSTALL*.txt
|
|
jpayne@68
|
409 were revised completely.
|
|
jpayne@68
|
410
|
|
jpayne@68
|
411 - windows/build-with-cmake.bat along with the instructions
|
|
jpayne@68
|
412 in windows/INSTALL-MinGW-w64_with_CMake.txt should make
|
|
jpayne@68
|
413 it very easy to build liblzma.dll and xz.exe on Windows
|
|
jpayne@68
|
414 using CMake and MinGW-w64 with either GCC or Clang/LLVM.
|
|
jpayne@68
|
415
|
|
jpayne@68
|
416 - windows/build.bash was updated. It now works on MSYS2 and
|
|
jpayne@68
|
417 on GNU/Linux (cross-compiling) to create a .zip and .7z
|
|
jpayne@68
|
418 package for 32-bit and 64-bit x86 using GCC + MinGW-w64.
|
|
jpayne@68
|
419
|
|
jpayne@68
|
420 * The TODO file is no longer installed as part of the
|
|
jpayne@68
|
421 documentation. The file is out of date and does not reflect
|
|
jpayne@68
|
422 the actual tasks that will be completed in the future.
|
|
jpayne@68
|
423
|
|
jpayne@68
|
424 * Translations:
|
|
jpayne@68
|
425
|
|
jpayne@68
|
426 - Translated lzmainfo man pages are now installed. These
|
|
jpayne@68
|
427 had been forgotten in earlier versions.
|
|
jpayne@68
|
428
|
|
jpayne@68
|
429 - Updated Croatian, Esperanto, German, Hungarian, Korean,
|
|
jpayne@68
|
430 Polish, Romanian, Spanish, Swedish, Vietnamese, and Ukrainian
|
|
jpayne@68
|
431 translations.
|
|
jpayne@68
|
432
|
|
jpayne@68
|
433 - Updated German, Korean, Romanian, and Ukrainian man page
|
|
jpayne@68
|
434 translations.
|
|
jpayne@68
|
435
|
|
jpayne@68
|
436 * Added a few tests.
|
|
jpayne@68
|
437
|
|
jpayne@68
|
438 Summary of new features added in the 5.5.x development releases:
|
|
jpayne@68
|
439
|
|
jpayne@68
|
440 * liblzma:
|
|
jpayne@68
|
441
|
|
jpayne@68
|
442 - LZMA decoder: Speed optimizations to the C code and
|
|
jpayne@68
|
443 added GCC & Clang compatible inline assembly for x86-64.
|
|
jpayne@68
|
444
|
|
jpayne@68
|
445 - Added lzma_mt_block_size() to recommend a Block size for
|
|
jpayne@68
|
446 multithreaded encoding.
|
|
jpayne@68
|
447
|
|
jpayne@68
|
448 - Added CLMUL-based CRC32 on x86-64 and E2K with runtime
|
|
jpayne@68
|
449 processor detection. Similar to CRC64, on 32-bit x86 it
|
|
jpayne@68
|
450 isn't available unless --disable-assembler is used.
|
|
jpayne@68
|
451
|
|
jpayne@68
|
452 - Optimized the CRC32 calculation on ARM64 platforms using the
|
|
jpayne@68
|
453 CRC32 instructions. Runtime detection for the instruction is
|
|
jpayne@68
|
454 used on GNU/Linux, FreeBSD, Windows, and macOS. If the
|
|
jpayne@68
|
455 compiler flags indicate unconditional CRC32 instruction
|
|
jpayne@68
|
456 support (+crc) then the generic version is not built.
|
|
jpayne@68
|
457
|
|
jpayne@68
|
458 - Added definitions of mask values like
|
|
jpayne@68
|
459 LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.
|
|
jpayne@68
|
460
|
|
jpayne@68
|
461 * xz:
|
|
jpayne@68
|
462
|
|
jpayne@68
|
463 - Multithreaded mode is now the default. This improves
|
|
jpayne@68
|
464 compression speed and creates .xz files that can be
|
|
jpayne@68
|
465 decompressed in multithreaded mode. The downsides are
|
|
jpayne@68
|
466 increased memory usage and slightly worse compression ratio.
|
|
jpayne@68
|
467
|
|
jpayne@68
|
468 - Added a new command line option --filters to set the filter
|
|
jpayne@68
|
469 chain using the liblzma filter string syntax.
|
|
jpayne@68
|
470
|
|
jpayne@68
|
471 - Added new command line options --filters1 ... --filters9 to
|
|
jpayne@68
|
472 set additional filter chains using the liblzma filter string
|
|
jpayne@68
|
473 syntax. The --block-list option now allows specifying filter
|
|
jpayne@68
|
474 chains that were set using these new options.
|
|
jpayne@68
|
475
|
|
jpayne@68
|
476 - Ported the command line tools to Windows MSVC.
|
|
jpayne@68
|
477 Visual Studio 2015 or later is required.
|
|
jpayne@68
|
478
|
|
jpayne@68
|
479 * Added lz4 support to xzdiff/xzcmp and xzgrep.
|
|
jpayne@68
|
480
|
|
jpayne@68
|
481
|
|
jpayne@68
|
482 5.5.2beta (2024-02-14)
|
|
jpayne@68
|
483
|
|
jpayne@68
|
484 * Licensing change: The core components are now under the
|
|
jpayne@68
|
485 BSD Zero Clause License (0BSD). In XZ Utils 5.4.6 and older
|
|
jpayne@68
|
486 and 5.5.1alpha these components are in the public domain and
|
|
jpayne@68
|
487 obviously remain so; the change affects the new releases only.
|
|
jpayne@68
|
488
|
|
jpayne@68
|
489 0BSD is an extremely permissive license which doesn't require
|
|
jpayne@68
|
490 retaining or reproducing copyright or license notices when
|
|
jpayne@68
|
491 distributing the code, thus in practice there is extremely
|
|
jpayne@68
|
492 little difference to public domain.
|
|
jpayne@68
|
493
|
|
jpayne@68
|
494 * liblzma
|
|
jpayne@68
|
495
|
|
jpayne@68
|
496 - Significant speed optimizations to the LZMA decoder were
|
|
jpayne@68
|
497 made. There are now three variants that can be chosen at
|
|
jpayne@68
|
498 build time:
|
|
jpayne@68
|
499
|
|
jpayne@68
|
500 * Basic C version: This is a few percent faster than
|
|
jpayne@68
|
501 5.4.x due to some new optimizations.
|
|
jpayne@68
|
502
|
|
jpayne@68
|
503 * Branchless C: This is currently the default on platforms
|
|
jpayne@68
|
504 for which there is no assembly code. This should be a few
|
|
jpayne@68
|
505 percent faster than the basic C version.
|
|
jpayne@68
|
506
|
|
jpayne@68
|
507 * x86-64 inline assembly. This works with GCC and Clang.
|
|
jpayne@68
|
508
|
|
jpayne@68
|
509 The default choice can currently be overridden by setting
|
|
jpayne@68
|
510 LZMA_RANGE_DECODER_CONFIG in CPPFLAGS: 0 means the basic
|
|
jpayne@68
|
511 version and 3 means that branchless C version.
|
|
jpayne@68
|
512
|
|
jpayne@68
|
513 - Optimized the CRC32 calculation on ARM64 platforms using the
|
|
jpayne@68
|
514 CRC32 instructions. The instructions are optional in ARMv8.0
|
|
jpayne@68
|
515 and are required in ARMv8.1 and later. Runtime detection for
|
|
jpayne@68
|
516 the instruction is used on GNU/Linux, FreeBSD, Windows, and
|
|
jpayne@68
|
517 macOS. If the compiler flags indicate unconditional CRC32
|
|
jpayne@68
|
518 instruction support (+crc) then the generic version is not
|
|
jpayne@68
|
519 built.
|
|
jpayne@68
|
520
|
|
jpayne@68
|
521 * Added lz4 support to xzdiff/xzcmp and xzgrep.
|
|
jpayne@68
|
522
|
|
jpayne@68
|
523 * Man pages of xzdiff/xzcmp, xzgrep, and xzmore were rewritten
|
|
jpayne@68
|
524 to simplify licensing of the man page translations.
|
|
jpayne@68

528 - Updated Chinese (simplified), German, Korean, Polish,
|
|
jpayne@68
|
529 Romanian, Spanish, Swedish, and Ukrainian translations.
|
|
jpayne@68
|
530
|
|
jpayne@68
|
531 - Updated German, Korean, Romanian, and Ukrainian man page
|
|
jpayne@68
|
532 translations.
|
|
jpayne@68
|
533
|
|
jpayne@68
|
534 * Small improvements to the tests.
|
|
jpayne@68
|
535
|
|
jpayne@68
|
536 * Added doc/examples/11_file_info.c. It was added to the Git
|
|
jpayne@68
|
537 repository in 2017 but forgotten to be added into distribution
|
|
jpayne@68
|
538 tarballs.
|
|
jpayne@68
|
539
|
|
jpayne@68
|
540 * Removed doc/examples_old. These were from 2012.
|
|
jpayne@68
|
541
|
|
jpayne@68
|
542 * Removed the macos/build.sh script. It had not been updated
|
|
jpayne@68
|
543 since 2013.
|
|
jpayne@68
|
544

|
546 5.5.1alpha (2024-01-26)
|
|
jpayne@68
|
547
|
|
jpayne@68
|
548 * Added a new filter for RISC-V binaries. The filter can be used
|
|
jpayne@68
|
549 for 32-bit and 64-bit binaries with either little or big
|
|
jpayne@68
|
550 endianness. In liblzma, the Filter ID is LZMA_FILTER_RISCV (0x0B)
|
|
jpayne@68
|
551 and the xz option is --riscv. liblzma filter string syntax
|
|
jpayne@68
|
552 recognizes this filter as "riscv".
|
|
jpayne@68
|
553
|
|
jpayne@68
|
554 * liblzma:
|
|
jpayne@68
|
555
|
|
jpayne@68
|
556 - Added lzma_mt_block_size() to recommend a Block size for
|
|
jpayne@68
|
557 multithreaded encoding
|
|
jpayne@68
|
558
|
|
jpayne@68
|
559 - Added CLMUL-based CRC32 on x86-64 and E2K with runtime
|
|
jpayne@68
|
560 processor detection. Similar to CRC64, on 32-bit x86 it
|
|
jpayne@68
|
561 isn't available unless --disable-assembler is used.
|
|
jpayne@68
|
562
|
|
jpayne@68
|
563 - Implemented GNU indirect function (IFUNC) as a runtime
|
|
jpayne@68
|
564 function dispatching method for CRC32 and CRC64 fast
|
|
jpayne@68
|
565 implementations on x86. Only GNU/Linux (glibc) and FreeBSD
|
|
jpayne@68
|
566 builds will use IFUNC, unless --enable-ifunc is specified to
|
|
jpayne@68
|
567 configure.
|
|
jpayne@68
|
568
|
|
jpayne@68
|
569 - Added definitions of mask values like
|
|
jpayne@68
|
570 LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.
|
|
jpayne@68
|
571
|
|
jpayne@68
|
572 - The XZ logo is now included in the Doxygen generated
|
|
jpayne@68
|
573 documentation. It is licensed under Creative Commons
|
|
jpayne@68
|
574 Attribution-ShareAlike 4.0.
|
|
jpayne@68
|
575
|
|
jpayne@68
|
576 * xz:
|
|
jpayne@68
|
577
|
|
jpayne@68
|
578 - Multithreaded mode is now the default. This improves
|
|
jpayne@68
|
579 compression speed and creates .xz files that can be
|
|
jpayne@68
|
580 decompressed multithreaded at the cost of increased memory
|
|
jpayne@68
|
581 usage and slightly worse compression ratio.
|
|
jpayne@68
|
582
|
|
jpayne@68
|
583 - Added new command line option --filters to set the filter
|
|
jpayne@68
|
584 chain using liblzma filter string syntax.
|
|
jpayne@68
|
585
|
|
jpayne@68
|
586 - Added new command line options --filters1 ... --filters9 to
|
|
jpayne@68
|
587 set additional filter chains using liblzma filter string
|
|
jpayne@68
|
588 syntax. The --block-list option now allows specifying filter
|
|
jpayne@68
|
589 chains that were set using these new options.
|
|
jpayne@68
|
590
|
|
jpayne@68
|
591 - Added support for Linux Landlock as a sandboxing method.
|
|
jpayne@68
|
592
|
|
jpayne@68
|
593 - xzdec now supports pledge(2), Capsicum, and Linux Landlock as
|
|
jpayne@68
|
594 sandboxing methods.
|
|
jpayne@68
|
595
|
|
jpayne@68
|
596 - Progress indicator time stats remain accurate after pausing
|
|
jpayne@68
|
597 xz with SIGTSTP.
|
|
jpayne@68
|
598
|
|
jpayne@68
|
599 - Ported xz and xzdec to Windows MSVC. Visual Studio 2015 or
|
|
jpayne@68
|
600 later is required.
|
|
jpayne@68
|
601
|
|
jpayne@68
|
602 * CMake Build:
|
|
jpayne@68
|
603
|
|
jpayne@68
|
604 - Supports pledge(2), Capsicum, and Linux Landlock sandboxing
|
|
jpayne@68
|
605 methods.
|
|
jpayne@68
|
606
|
|
jpayne@68
|
607 - Replacement functions for getopt_long() are used on platforms
|
|
jpayne@68
|
608 that do not have it.
|
|
jpayne@68
|
609
|
|
jpayne@68
|
610 * Enabled unaligned access by default on PowerPC64LE and on RISC-V
|
|
jpayne@68
|
611 targets that define __riscv_misaligned_fast.
|
|
jpayne@68
|
612
|
|
jpayne@68
|
613 * Tests:
|
|
jpayne@68
|
614
|
|
jpayne@68
|
615 - Added two new fuzz targets to OSS-Fuzz.
|
|
jpayne@68
|
616
|
|
jpayne@68
|
617 - Implemented Continuous Integration (CI) testing using
|
|
jpayne@68
|
618 GitHub Actions.
|
|
jpayne@68
|
619
|
|
jpayne@68
|
620 * Changed quoting style from `...' to '...' in all messages,
|
|
jpayne@68
|
621 scripts, and documentation.
|
|
jpayne@68
|
622
|
|
jpayne@68
|
623 * Added basic Codespell support to help catch typo errors.
|
|
jpayne@68
|
624
|
|
jpayne@68
|
625
|
|
jpayne@68
|
626 5.4.7 (2024-05-29)
|
|
jpayne@68
|
627
|
|
jpayne@68
|
628 * Not changed: Memory sanitizer (MSAN) has a false positive
|
|
jpayne@68
|
629 in the CRC CLMUL code which also makes OSS Fuzz unhappy.
|
|
jpayne@68
|
630 Valgrind is smarter and doesn't complain.
|
|
jpayne@68
|
631
|
|
jpayne@68
|
632 A revision to the CLMUL code is coming anyway and this issue
|
|
jpayne@68
|
633 will be cleaned up as part of it. It won't be backported to
|
|
jpayne@68
|
634 5.6.x or 5.4.x because the old code isn't wrong. There is
|
|
jpayne@68
|
635 no reason to risk introducing regressions in old branches
|
|
jpayne@68
|
636 just to silence a false positive.
|
|
jpayne@68
|
637
|
|
jpayne@68
|
638 * liblzma:
|
|
jpayne@68
|
639
|
|
jpayne@68
|
640 - lzma_index_decoder() and lzma_index_buffer_decode(): Fix
|
|
jpayne@68
|
641 a missing output pointer initialization (*i = NULL) if the
|
|
jpayne@68
|
642 functions are called with invalid arguments. The API docs
|
|
jpayne@68
|
643 say that such an initialization is always done. In practice
|
|
jpayne@68
|
644 this matters very little because the problem can only occur
|
|
jpayne@68
|
645 if the calling application has a bug and these functions
|
|
jpayne@68
|
646 return LZMA_PROG_ERROR.
|
|
jpayne@68
|
647
|
|
jpayne@68
|
648 - lzma_str_to_filters(): Fix a missing output pointer
|
|
jpayne@68
|
649 initialization (*error_pos = 0). This is very similar
|
|
jpayne@68
|
650 to the fix above.
|
|
jpayne@68
|
651
|
|
jpayne@68
|
652 - Fix C standard conformance with function pointer types.
|
|
jpayne@68
|
653 This newly showed up with Clang 17 with -fsanitize=undefined.
|
|
jpayne@68
|
654 There are no bug reports about this.
|
|
jpayne@68
|
655
|
|
jpayne@68
|
656 - Fix building with NVIDIA HPC SDK.
|
|
jpayne@68
|
657
|
|
jpayne@68
|
658 * xz:
|
|
jpayne@68
|
659
|
|
jpayne@68
|
660 - Fix a C standard conformance issue in --block-list parsing
|
|
jpayne@68
|
661 (arithmetic on a null pointer).
|
|
jpayne@68
|
662
|
|
jpayne@68
|
663 - Fix a warning from GNU groff when processing the man page:
|
|
jpayne@68
|
664 "warning: cannot select font 'CW'"
|
|
jpayne@68
|
665
|
|
jpayne@68
|
666 - Fix outdated threading related information on the man page.
|
|
jpayne@68
|
667
|
|
jpayne@68
|
668 * xzless:
|
|
jpayne@68
|
669
|
|
jpayne@68
|
670 - With "less" version 451 and later, use "||-" instead of "|-"
|
|
jpayne@68
|
671 in the environment variable LESSOPEN. This way compressed
|
|
jpayne@68
|
672 files that contain no uncompressed data are shown correctly
|
|
jpayne@68
|
673 as empty.
|
|
jpayne@68
|
674
|
|
jpayne@68
|
675 - With "less" version 632 and later, use --show-preproc-errors
|
|
jpayne@68
|
676 to make "less" show a warning on decompression errors.
|
|
jpayne@68
|
677
|
|
jpayne@68
|
678 * Autotools-based build system (configure):
|
|
jpayne@68
|
679
|
|
jpayne@68
|
680 - Symbol versioning variant can now be overridden with
|
|
jpayne@68
|
681 --enable-symbol-versions. Documentation in INSTALL was
|
|
jpayne@68
|
682 updated to match.
|
|
jpayne@68
|
683
|
|
jpayne@68
|
684 CMake:
|
|
jpayne@68
|
685
|
|
jpayne@68
|
686 - Linux on MicroBlaze is handled specially now. This matches
|
|
jpayne@68
|
687 the changes made to the Autotools-based build in XZ Utils
|
|
jpayne@68
|
688 5.4.2 and 5.2.11.
|
|
jpayne@68
|
689
|
|
jpayne@68
|
690 - Disable symbol versioning on non-glibc Linux to match what
|
|
jpayne@68
|
691 the Autotools build does. For example, symbol versioning
|
|
jpayne@68
|
692 isn't enabled with musl.
|
|
jpayne@68
|
693
|
|
jpayne@68
|
694 - Symbol versioning variant can now be overridden by setting
|
|
jpayne@68
|
695 SYMBOL_VERSIONING to "OFF", "generic", or "linux".
|
|
jpayne@68
|
696
|
|
jpayne@68
|
697 * Documentation:
|
|
jpayne@68
|
698
|
|
jpayne@68
|
699 - Clarify the description of --disable-assembler in INSTALL.
|
|
jpayne@68
|
700 The option only affects 32-bit x86 assembly usage.
|
|
jpayne@68
|
701
|
|
jpayne@68
|
702 - Add doc/examples/11_file_info.c. It was added to the
|
|
jpayne@68
|
703 Git repository in 2017 but forgotten to be added into
|
|
jpayne@68
|
704 distribution tarballs.
|
|
jpayne@68
|
705
|
|
jpayne@68
|
706 - Don't install the TODO file as part of the documentation.
|
|
jpayne@68
|
707 The file is out of date.
|
|
jpayne@68
|
708
|
|
jpayne@68
|
709 - Update home page URLs back to their old locations on
|
|
jpayne@68
|
710 tukaani.org.
|
|
jpayne@68
|
711
|
|
jpayne@68
|
712 - Update maintainer info.
|
|
jpayne@68
|
713
|
|
jpayne@68
|
714
|
|
jpayne@68
|
715 5.4.6 (2024-01-26)
|
|
jpayne@68
|
716
|
|
jpayne@68
|
717 * Fixed a bug involving internal function pointers in liblzma not
|
|
jpayne@68
|
718 being initialized to NULL. The bug can only be triggered if
|
|
jpayne@68
|
719 lzma_filters_update() is called on a LZMA1 encoder, so it does
|
|
jpayne@68
|
720 not affect xz or any application known to us that uses liblzma.
|
|
jpayne@68
|
721
|
|
jpayne@68
|
722 * xz:
|
|
jpayne@68
|
723
|
|
jpayne@68
|
724 - Fixed a regression introduced in 5.4.2 that caused encoding
|
|
jpayne@68
|
725 in the raw format to unnecessarily fail if --suffix was not
|
|
jpayne@68
|
726 used. For instance, the following command no longer reports
|
|
jpayne@68
|
727 that --suffix must be used:
|
|
jpayne@68
|
728
|
|
jpayne@68
|
729 echo foo | xz --format=raw --lzma2 | wc -c
|
|
jpayne@68
|
730
|
|
jpayne@68
|
731 - Fixed an issue on MinGW-w64 builds that prevented reading
|
|
jpayne@68
|
732 from or writing to non-terminal character devices like NUL.
|
|
jpayne@68
|
733
|
|
jpayne@68
|
734 * Added a new test.
|
|
jpayne@68
|
735
|
|
jpayne@68
|
736
|
|
jpayne@68
|
737 5.4.5 (2023-11-01)
|
|
jpayne@68
|
738
|
|
jpayne@68
|
739 * liblzma:
|
|
jpayne@68
|
740
|
|
jpayne@68
|
741 - Use __attribute__((__no_sanitize_address__)) to avoid address
|
|
jpayne@68
|
742 sanitization with CRC64 CLMUL. It uses 16-byte-aligned reads
|
|
jpayne@68
|
743 which can extend past the bounds of the input buffer and
|
|
jpayne@68
|
744 inherently trigger address sanitization errors. This isn't
|
|
jpayne@68
|
745 a bug.
|
|
jpayne@68
|
746
|
|
jpayne@68
|
747 - Fixed an assertion failure that could be triggered by a large
|
|
jpayne@68
|
748 unpadded_size argument. It was verified that there was no
|
|
jpayne@68
|
749 other bug than the assertion failure.
|
|
jpayne@68
|
750
|
|
jpayne@68
|
751 - Fixed a bug that prevented building with Windows Vista
|
|
jpayne@68
|
752 threading when __attribute__((__constructor__)) is not
|
|
jpayne@68
|
753 supported.
|
|
jpayne@68
|
754
|
|
jpayne@68
|
755 * xz now properly handles special files such as "con" or "nul" on
|
|
jpayne@68
|
756 Windows. Before this fix, the following wrote "foo" to the
|
|
jpayne@68
|
757 console and deleted the input file "con_xz":
|
|
jpayne@68
|
758
|
|
jpayne@68
|
759 echo foo | xz > con_xz
|
|
jpayne@68
|
760 xz --suffix=_xz --decompress con_xz
|
|
jpayne@68
|
761
|
|
jpayne@68
|
762 * Build systems:
|
|
jpayne@68
|
763
|
|
jpayne@68
|
764 - Allow builds with Windows win95 threading and small mode when
|
|
jpayne@68
|
765 __attribute__((__constructor__)) is supported.
|
|
jpayne@68
|
766
|
|
jpayne@68
|
767 - Added a new line to liblzma.pc for MSYS2 (Windows):
|
|
jpayne@68
|
768
|
|
jpayne@68
|
769 Cflags.private: -DLZMA_API_STATIC
|
|
jpayne@68
|
770
|
|
jpayne@68
|
771 When compiling code that will link against static liblzma,
|
|
jpayne@68
|
772 the LZMA_API_STATIC macro needs to be defined on Windows.
|
|
jpayne@68
|
773
|
|
jpayne@68
|
774 - CMake specific changes:
|
|
jpayne@68
|
775
|
|
jpayne@68
|
776 * Fixed a bug that allowed CLOCK_MONOTONIC to be used even
|
|
jpayne@68
|
777 if the check for it failed.
|
|
jpayne@68
|
778
|
|
jpayne@68
|
779 * Fixed a bug where configuring CMake multiple times
|
|
jpayne@68
|
780 resulted in HAVE_CLOCK_GETTIME and HAVE_CLOCK_MONOTONIC
|
|
jpayne@68
|
781 not being set.
|
|
jpayne@68
|
782
|
|
jpayne@68
|
783 * Fixed the build with MinGW-w64-based Clang/LLVM 17.
|
|
jpayne@68
|
784 llvm-windres now has more accurate GNU windres emulation
|
|
jpayne@68
|
785 so the GNU windres workaround from 5.4.1 is needed with
|
|
jpayne@68
|
786 llvm-windres version 17 too.
|
|
jpayne@68
|
787
|
|
jpayne@68
|
788 * The import library on Windows is now properly named
|
|
jpayne@68
|
789 "liblzma.dll.a" instead of "libliblzma.dll.a"
|
|
jpayne@68
|
790
|
|
jpayne@68
|
791 * Fixed a bug causing the Ninja Generator to fail on
|
|
jpayne@68
|
792 UNIX-like systems. This bug was introduced in 5.4.0.
|
|
jpayne@68
|
793
|
|
jpayne@68
|
794 * Added a new option to disable CLMUL CRC64.

795
|
|
jpayne@68
|
796 * A module-definition (.def) file is now created when
|
|
jpayne@68
|
797 building liblzma.dll with MinGW-w64.
|
|
jpayne@68
|
798
|
|
jpayne@68
|
799 * The pkg-config liblzma.pc file is now installed on all
|
|
jpayne@68
|
800 builds except when using MSVC on Windows.
|
|
jpayne@68
|
801
|
|
jpayne@68
|
802 * Added large file support by default for platforms that
|
|
jpayne@68
|
803 need it to handle files larger than 2 GiB. This includes
|
|
jpayne@68
|
804 MinGW-w64, even 64-bit builds.
|
|
jpayne@68
|
805
|
|
jpayne@68
|
806 * Small fixes and improvements to the tests.
|
|
jpayne@68
|
807
|
|
jpayne@68
|
808 * Updated translations: Chinese (simplified) and Esperanto.

811 5.4.4 (2023-08-02)
|
|
jpayne@68
|
812
|
|
jpayne@68
|
813 * liblzma and xzdec can now build against WASI SDK when threading
|
|
jpayne@68
|
814 support is disabled. xz and tests don't build yet.
|
|
jpayne@68
|
815
|
|
jpayne@68
|
816 * CMake:
|
|
jpayne@68
|
817
|
|
jpayne@68
|
818 - Fixed a bug preventing other projects from including liblzma
|
|
jpayne@68
|
819 multiple times using find_package().
|
|
jpayne@68
|
820
|
|
jpayne@68
|
821 - Don't create broken symlinks in Cygwin and MSYS2 unless
|
|
jpayne@68
|
822 supported by the environment. This prevented building for the
|
|
jpayne@68
|
823 default MSYS2 environment. The problem was introduced in
|
|
jpayne@68
|
824 xz 5.4.0.
|
|
jpayne@68
|
825
|
|
jpayne@68
|
826 * Documentation:
|
|
jpayne@68
|
827
|
|
jpayne@68
|
828 - Small improvements to man pages.
|
|
jpayne@68

jpayne@68
|
832
|
|
jpayne@68
|
833 * Tests:
|
|
jpayne@68
|
834
|
|
jpayne@68
|
835 - Added a new section to INSTALL to describe basic test usage
|
|
jpayne@68
|
836 and address recent questions about building the tests when
|
|
jpayne@68
|
837 cross compiling.
|
|
jpayne@68
|
838
|
|
jpayne@68
|
839 - Small fixes and improvements to the tests.
|
|

|
841 * Translations:
|
|
jpayne@68
|
842
|
|
jpayne@68
|
843 - Fixed a mistake that caused one of the error messages to not
|
|
jpayne@68
|
844 be translated. This only affected versions 5.4.2 and 5.4.3.
|
|
jpayne@68
|
845
|
|
jpayne@68
|
846 - Updated the Chinese (simplified), Croatian, Esperanto, German,
|
|
jpayne@68
|
847 Korean, Polish, Romanian, Spanish, Swedish, Ukrainian, and
|
|
jpayne@68
|
848 Vietnamese translations.
|
|
jpayne@68
|
849
|
|
jpayne@68
|
850 - Updated the German, Korean, Romanian, and Ukrainian man page
|

|
|
jpayne@68
|
855
|
|
jpayne@68
|
856 * All fixes from 5.2.12
|
|
jpayne@68
|
857
|
|
jpayne@68
|
858 * Features in the CMake build can now be disabled as CMake cache
|
|
jpayne@68
|
859 variables, similar to the Autotools build.
|
|
jpayne@68
|
860
|
|
jpayne@68
|
861 * Minor update to the Croatian translation.
|

864 5.4.2 (2023-03-18)
|
|
jpayne@68
|
865
|
|
jpayne@68
|
866 * All fixes from 5.2.11 that were not included in 5.4.1.
|
|
jpayne@68
|
867
|
|
jpayne@68
|
868 * If xz is built with support for the Capsicum sandbox but running
|
|
jpayne@68
|
869 in an environment that doesn't support Capsicum, xz now runs
|
|
jpayne@68
|
870 normally without sandboxing instead of exiting with an error.
|
|
jpayne@68
|
871
|
|
jpayne@68
|
872 * liblzma:
|
|
jpayne@68
|
873
|
|
jpayne@68
|
874 - Documentation was updated to improve the style, consistency,
|
|
jpayne@68
|
875 and completeness of the liblzma API headers.
|
|
jpayne@68
|
876
|
|
jpayne@68
|
877 - The Doxygen-generated HTML documentation for the liblzma API
|
|
jpayne@68
|
878 header files is now included in the source release and is
|
|
jpayne@68
|
879 installed as part of "make install". All JavaScript is
|
|
jpayne@68
|
880 removed to simplify license compliance and to reduce the
|
|
jpayne@68
|
881 install size.
|
|
jpayne@68
|
882
|
|
jpayne@68
|
883 - Fixed a minor bug in lzma_str_from_filters() that produced
|
|
jpayne@68
|
884 too many filters in the output string instead of reporting
|
|
jpayne@68
|
885 an error if the input array had more than four filters. This
|
|
jpayne@68
|
886 bug did not affect xz.
|
|
jpayne@68
|
887
|
|
jpayne@68
|
888 * Build systems:
|
|
jpayne@68
|
889
|
|
jpayne@68
|
890 - autogen.sh now invokes the doxygen tool via the new wrapper
|
|
jpayne@68
|
891 script doxygen/update-doxygen, unless the command line option
|
|
jpayne@68
|
892 --no-doxygen is used.
|
|
jpayne@68
|
893
|
|
jpayne@68
|
894 - Added microlzma_encoder.c and microlzma_decoder.c to the
|
|
jpayne@68
|
895 VS project files for Windows and to the CMake build. These
|
|
jpayne@68
|
896 should have been included in 5.3.2alpha.
|
|
jpayne@68
|
897
|
|
jpayne@68
|
898 * Tests:
|
|
jpayne@68
|
899
|
|
jpayne@68
|
900 - Added a test to the CMake build that was forgotten in the
|
|
jpayne@68
|
901 previous release.
|
|
jpayne@68
|
902
|
|
jpayne@68
|
903 - Added and refactored a few tests.
|
|
jpayne@68
|
904
|
|
jpayne@68
|
905 * Translations:
|
|
jpayne@68
|
906
|
|
jpayne@68
|
907 - Updated the Brazilian Portuguese translation.
|
|
jpayne@68
|
908
|
|
jpayne@68
|
909 - Added Brazilian Portuguese man page translation.
|

912 5.4.1 (2023-01-11)
|
|
jpayne@68
|
913
|
|
jpayne@68
|
914 * liblzma:
|
|
jpayne@68
|
915
|
|
jpayne@68
|
916 - Fixed the return value of lzma_microlzma_encoder() if the
|
|
jpayne@68
|
917 LZMA options lc/lp/pb are invalid. Invalid lc/lp/pb options
|
|
jpayne@68
|
918 made the function return LZMA_STREAM_END without encoding
|
|
jpayne@68
|
919 anything instead of returning LZMA_OPTIONS_ERROR.
|
|
jpayne@68
|
920
|
|
jpayne@68
|
921 - Windows / Visual Studio: Workaround a possible compiler bug
|
|
jpayne@68
|
922 when targeting 32-bit x86 and compiling the CLMUL version of
|
|
jpayne@68
|
923 the CRC64 code. The CLMUL code isn't enabled by the Windows
|
|
jpayne@68
|
924 project files but it is in the CMake-based builds.
|
|
jpayne@68
|
925
|
|
jpayne@68
|
926 * Build systems:
|
|
jpayne@68
|
927
|
|
jpayne@68
|
928 - Windows-specific CMake changes:
|
|
jpayne@68
|
929
|
|
jpayne@68
|
930 * Don't try to enable CLMUL CRC64 code if _mm_set_epi64x()
|
|
jpayne@68
|
931 isn't available. This fixes CMake-based build with Visual
|
|
jpayne@68
|
932 Studio 2013.
|
|
jpayne@68
|
933
|
|
jpayne@68
|
934 * Created a workaround for a build failure with windres
|
|
jpayne@68
|
935 from GNU binutils. It is used only when the C compiler
|
|
jpayne@68
|
936 is GCC (not Clang). The workaround is incompatible
|
|
jpayne@68
|
937 with llvm-windres, resulting in "XZx20Utils" instead
|
|
jpayne@68
|
938 of "XZ Utils" in the resource file, but without the
|
|
jpayne@68
|
939 workaround llvm-windres works correctly. See the
|
|
jpayne@68
|
940 comment in CMakeLists.txt for details.
|
|
jpayne@68
|
941
|
|
jpayne@68
|
942 * Included the resource files in the xz and xzdec build
|
|
jpayne@68
|
943 rules. Building the command line tools is still
|
|
jpayne@68
|
944 experimental but possible with MinGW-w64.
|
|
jpayne@68
|
945
|
|
jpayne@68
|
946 - Visual Studio: Added stream_decoder_mt.c to the project
|
|
jpayne@68
|
947 files. Now the threaded decompressor lzma_stream_decoder_mt()
|
|
jpayne@68
|
948 gets built. CMake-based build wasn't affected.
|
|
jpayne@68
|
949
|
|
jpayne@68
|
950 - Updated windows/INSTALL-MSVC.txt to mention that CMake-based
|
|
jpayne@68
|
951 build is now the preferred method with Visual Studio. The
|
|
jpayne@68
|
952 project files will probably be removed after 5.4.x releases.
|
|
jpayne@68
|
953
|
|
jpayne@68
|
954 - Changes to #defines in config.h:
|
|
jpayne@68
|
955
|
|
jpayne@68
|
956 * HAVE_DECL_CLOCK_MONOTONIC was replaced by
|
|
jpayne@68
|
957 HAVE_CLOCK_MONOTONIC. The old macro was always defined
|
|
jpayne@68
|
958 in configure-generated config.h to either 0 or 1. The
|
|
jpayne@68
|
959 new macro is defined (to 1) only if the declaration of
|
|
jpayne@68
|
960 CLOCK_MONOTONIC is available. This matches the way most
|
|
jpayne@68
|
961 other config.h macros work and makes things simpler with
|
|
jpayne@68
|
962 other build systems.
|
|
jpayne@68
|
963
|
|
jpayne@68
|
964 * HAVE_DECL_PROGRAM_INVOCATION_NAME was replaced by
|
|
jpayne@68
|
965 HAVE_PROGRAM_INVOCATION_NAME for the same reason.
|
|
jpayne@68
|
966
|
|
jpayne@68
|
967 * Tests:
|
|
jpayne@68
|
968
|
|
jpayne@68
|
969 - Fixed test script compatibility with ancient /bin/sh
|
|
jpayne@68
|
970 versions. Now the five test_compress_* tests should
|
|
jpayne@68
|
971 no longer fail on Solaris 10.
|
|
jpayne@68
|
972
|
|
jpayne@68
|
973 - Added and refactored a few tests.
|
|
jpayne@68
|
974
|
|
jpayne@68
|
975 * Translations:
|
|
jpayne@68
|
976
|
|
jpayne@68
|
977 - Updated the Catalan and Esperanto translations.
|
|
jpayne@68
|
978
|
|
jpayne@68
|
979 - Added Korean and Ukrainian man page translations.
|

|
|
jpayne@68
|
981
|
|
jpayne@68
|
982 5.4.0 (2022-12-13)
|
|
jpayne@68
|
983
|
|
jpayne@68
|
984 This bumps the minor version of liblzma because new features were
|
|
jpayne@68
|
985 added. The API and ABI are still backward compatible with liblzma
|
|
jpayne@68
|
986 5.2.x and 5.0.x.
|
|
jpayne@68
|
987
|
|
jpayne@68
|
988 Since 5.3.5beta:
|
|
jpayne@68
|
989
|
|
jpayne@68
|
990 * All fixes from 5.2.10.
|
|
jpayne@68
|
991
|
|
jpayne@68
|
992 * The ARM64 filter is now stable. The xz option is now --arm64.
|
|
jpayne@68
|
993 Decompression requires XZ Utils 5.4.0. In the future the ARM64
|
|
jpayne@68
|
994 filter will be supported by XZ for Java, XZ Embedded (including
|
|
jpayne@68
|
995 the version in Linux), LZMA SDK, and 7-Zip.
|
|
jpayne@68
|
996
|
|
jpayne@68
|
997 * Translations:
|
|
jpayne@68
|
998
|
|
jpayne@68
|
999 - Updated Catalan, Croatian, German, Romanian, and Turkish
|
|
jpayne@68
|
1000 translations.
|
|
jpayne@68
|
1001
|
|
jpayne@68
|
1002 - Updated German man page translations.
|
|
jpayne@68
|
1003
|
|
jpayne@68
|
1004 - Added Romanian man page translations.
|
|
jpayne@68
|
1005
|
|
jpayne@68
|
1006 Summary of new features added in the 5.3.x development releases:
|
|
jpayne@68
|
1007
|
|
jpayne@68
|
1008 * liblzma:
|
|
jpayne@68
|
1009
|
|
jpayne@68
|
1010 - Added threaded .xz decompressor lzma_stream_decoder_mt().
|
|
jpayne@68
|
1011 It can use multiple threads with .xz files that have multiple
|
|
jpayne@68
|
1012 Blocks with size information in Block Headers. The threaded
|
|
jpayne@68
|
1013 encoder in xz has always created such files.
|
|
jpayne@68
|
1014
|
|
jpayne@68
|
1015 Single-threaded encoder cannot store the size information in
|
|
jpayne@68
|
1016 Block Headers even if one used LZMA_FULL_FLUSH to create
|
|
jpayne@68
|
1017 multiple Blocks, so this threaded decoder cannot use multiple
|
|
jpayne@68
|
1018 threads with such files.
|
|
jpayne@68
|
1019
|
|
jpayne@68
|
1020 If there are multiple Streams (concatenated .xz files), one
|
|
jpayne@68
|
1021 Stream will be decompressed completely before starting the
|
|
jpayne@68
|
1022 next Stream.
|
|
jpayne@68
|
1023
|
|
jpayne@68
|
1024 - A new decoder flag LZMA_FAIL_FAST was added. It makes the
|
|
jpayne@68
|
1025 threaded decompressor report errors soon instead of first
|
|
jpayne@68
|
1026 flushing all pending data before the error location.
|
|
jpayne@68
|
1027
|
|
jpayne@68
|
1028 - New Filter IDs:
|
|
jpayne@68
|
1029 * LZMA_FILTER_ARM64 is for ARM64 binaries.
|
|
jpayne@68
|
1030 * LZMA_FILTER_LZMA1EXT is for raw LZMA1 streams that don't
|
|
jpayne@68
|
1031 necessarily use the end marker.
|
|
jpayne@68
|
1032
|
|
jpayne@68
|
1033 - Added lzma_str_to_filters(), lzma_str_from_filters(), and
|
|
jpayne@68
|
1034 lzma_str_list_filters() to convert a preset or a filter chain
|
|
jpayne@68
|
1035 string to a lzma_filter[] and vice versa. These should make
|
|
jpayne@68
|
1036 it easier to write applications that allow users to specify
|
|
jpayne@68
|
1037 custom compression options.
|
|
jpayne@68
|
1038
|
|
jpayne@68
|
1039 - Added lzma_filters_free() which can be convenient for freeing
|
|
jpayne@68
|
1040 the filter options in a filter chain (an array of lzma_filter
|
|
jpayne@68
|
1041 structures).
|
|
jpayne@68
|
1042
|
|
jpayne@68
|
1043 - lzma_file_info_decoder() to makes it a little easier to get
|
|
jpayne@68
|
1044 the Index field from .xz files. This helps in getting the
|
|
jpayne@68
|
1045 uncompressed file size but an easy-to-use random access
|
|
jpayne@68
|
1046 API is still missing which has existed in XZ for Java for
|
|
jpayne@68
|
1047 a long time.
|
|
jpayne@68
|
1048
|
|
jpayne@68
|
1049 - Added lzma_microlzma_encoder() and lzma_microlzma_decoder().
|
|
jpayne@68
|
1050 It is used by erofs-utils and may be used by others too.
|
|
jpayne@68
|
1051
|
|
jpayne@68
|
1052 The MicroLZMA format is a raw LZMA stream (without end marker)
|
|
jpayne@68
|
1053 whose first byte (always 0x00) has been replaced with
|
|
jpayne@68
|
1054 bitwise-negation of the LZMA properties (lc/lp/pb). It was
|
|
jpayne@68
|
1055 created for use in EROFS but may be used in other contexts
|
|
jpayne@68
|
1056 as well where it is important to avoid wasting bytes for
|
|
jpayne@68
|
1057 stream headers or footers. The format is also supported by
|
|
jpayne@68
|
1058 XZ Embedded (the XZ Embedded version in Linux got MicroLZMA
|
|
jpayne@68
|
1059 support in Linux 5.16).
|
|
jpayne@68
|
1060
|
|
jpayne@68
|
1061 The MicroLZMA encoder API in liblzma can compress into a
|
|
jpayne@68
|
1062 fixed-sized output buffer so that as much data is compressed
|
|
jpayne@68
|
1063 as can be fit into the buffer while still creating a valid
|
|
jpayne@68
|
1064 MicroLZMA stream. This is needed for EROFS.
|
|
jpayne@68
|
1065
|
|
jpayne@68
|
1066 - Added lzma_lzip_decoder() to decompress the .lz (lzip) file
|
|
jpayne@68
|
1067 format version 0 and the original unextended version 1 files.
|
|
jpayne@68
|
1068 Also lzma_auto_decoder() supports .lz files.
|
|
jpayne@68
|
1069
|
|
jpayne@68
|
1070 - lzma_filters_update() can now be used with the multi-threaded
|
|
jpayne@68
|
1071 encoder (lzma_stream_encoder_mt()) to change the filter chain
|
|
jpayne@68
|
1072 after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH.
|
|
jpayne@68
|
1073
|
|
jpayne@68
|
1074 - In lzma_options_lzma, allow nice_len = 2 and 3 with the match
|
|
jpayne@68
|
1075 finders that require at least 3 or 4. Now it is internally
|
|
jpayne@68
|
1076 rounded up if needed.
|
|
jpayne@68
|
1077
|
|
jpayne@68
|
1078 - CLMUL-based CRC64 on x86-64 and E2K with runtime processor
|
|
jpayne@68
|
1079 detection. On 32-bit x86 it currently isn't available unless
|
|
jpayne@68
|
1080 --disable-assembler is used which can make the non-CLMUL
|
|
jpayne@68
|
1081 CRC64 slower; this might be fixed in the future.
|
|
jpayne@68
|
1082
|
|
jpayne@68
|
1083 - Building with --disable-threads --enable-small
|
|
jpayne@68
|
1084 is now thread-safe if the compiler supports
|
|
jpayne@68
|
1085 __attribute__((__constructor__)).
|
|
jpayne@68
|
1086
|
|
jpayne@68
|
1087 * xz:
|
|
jpayne@68
|
1088
|
|
jpayne@68
|
1089 - Using -T0 (--threads=0) will now use multi-threaded encoder
|
|
jpayne@68
|
1090 even on a single-core system. This is to ensure that output
|
|
jpayne@68
|
1091 from the same xz binary is identical on both single-core and
|
|
jpayne@68
|
1092 multi-core systems.
|
|
jpayne@68
|
1093
|
|
jpayne@68
|
1094 - --threads=+1 or -T+1 is now a way to put xz into
|
|
jpayne@68
|
1095 multi-threaded mode while using only one worker thread.
|
|
jpayne@68
|
1096 The + is ignored if the number is not 1.
|
|
jpayne@68
|
1097
|
|
jpayne@68
|
1098 - A default soft memory usage limit is now used for compression
|
|
jpayne@68
|
1099 when -T0 is used and no explicit limit has been specified.
|
|
jpayne@68
|
1100 This soft limit is used to restrict the number of threads
|
|
jpayne@68
|
1101 but if the limit is exceeded with even one thread then xz
|
|
jpayne@68
|
1102 will continue with one thread using the multi-threaded
|
|
jpayne@68
|
1103 encoder and this limit is ignored. If the number of threads
|
|
jpayne@68
|
1104 is specified manually then no default limit will be used;
|
|
jpayne@68
|
1105 this affects only -T0.
|
|
jpayne@68
|
1106
|
|
jpayne@68
|
1107 This change helps on systems that have very many cores and
|
|
jpayne@68
|
1108 using all of them for xz makes no sense. Previously xz -T0
|
|
jpayne@68
|
1109 could run out of memory on such systems because it attempted
|
|
jpayne@68
|
1110 to reserve memory for too many threads.
|
|
jpayne@68
|
1111
|
|
jpayne@68
|
1112 This also helps with 32-bit builds which don't have a large
|
|
jpayne@68
|
1113 amount of address space that would be required for many
|
|
jpayne@68
|
1114 threads. The default soft limit for -T0 is at most 1400 MiB
|
|
jpayne@68
|
1115 on all 32-bit platforms.
|
|
jpayne@68
|
1116
|
|
jpayne@68
|
1117 - Previously a low value in --memlimit-compress wouldn't cause
|
|
jpayne@68
|
1118 xz to switch from multi-threaded mode to single-threaded mode
|
|
jpayne@68
|
1119 if the limit cannot otherwise be met; xz failed instead. Now
|
|
jpayne@68
|
1120 xz can switch to single-threaded mode and then, if needed,
|
|
jpayne@68
|
1121 scale down the LZMA2 dictionary size too just like it already
|
|
jpayne@68
|
1122 did when it was started in single-threaded mode.
|
|
jpayne@68
|
1123
|
|
jpayne@68
|
1124 - The option --no-adjust no longer prevents xz from scaling down
|
|
jpayne@68
|
1125 the number of threads as that doesn't affect the compressed
|
|
jpayne@68
|
1126 output (only performance). Now --no-adjust only prevents
|
|
jpayne@68
|
1127 adjustments that affect compressed output, that is, with
|
|
jpayne@68
|
1128 --no-adjust xz won't switch from multi-threaded mode to
|
|
jpayne@68
|
1129 single-threaded mode and won't scale down the LZMA2
|
|
jpayne@68
|
1130 dictionary size.
|
|
jpayne@68
|
1131
|
|
jpayne@68
|
1132 - Added a new option --memlimit-mt-decompress=LIMIT. This is
|
|
jpayne@68
|
1133 used to limit the number of decompressor threads (possibly
|
|
jpayne@68
|
1134 falling back to single-threaded mode) but it will never make
|
|
jpayne@68
|
1135 xz refuse to decompress a file. This has a system-specific
|
|
jpayne@68
|
1136 default value because without any limit xz could end up
|
|
jpayne@68
|
1137 allocating memory for the whole compressed input file, the
|
|
jpayne@68
|
1138 whole uncompressed output file, multiple thread-specific
|
|
jpayne@68
|
1139 decompressor instances and so on. Basically xz could
|
|
jpayne@68
|
1140 attempt to use an insane amount of memory even with fairly
|
|
jpayne@68
|
1141 common files. The system-specific default value is currently
|
|
jpayne@68
|
1142 the same as the one used for compression with -T0.
|
|
jpayne@68
|
1143
|
|
jpayne@68
|
1144 The new option works together with the existing option
|
|
jpayne@68
|
1145 --memlimit-decompress=LIMIT. The old option sets a hard limit
|
|
jpayne@68
|
1146 that must not be exceeded (xz will refuse to decompress)
|
|
jpayne@68
|
1147 while the new option only restricts the number of threads.
|
|
jpayne@68
|
1148 If the limit set with --memlimit-mt-decompress is greater
|
|
jpayne@68
|
1149 than the limit set with --memlimit-compress, then the latter
|
|
jpayne@68
|
1150 value is used also for --memlimit-mt-decompress.
|
|
jpayne@68
|
1151
|
|
jpayne@68
|
1152 - Added new information to the output of xz --info-memory and
|
|
jpayne@68
|
1153 new fields to the output of xz --robot --info-memory.
|
|
jpayne@68
|
1154
|
|
jpayne@68
|
1155 - In --lzma2=nice=NUMBER allow 2 and 3 with all match finders
|
|
jpayne@68
|
1156 now that liblzma handles it.
|
|
jpayne@68
|
1157
|
|
jpayne@68
|
1158 - Don't mention endianness for ARM and ARM-Thumb filters in
|
|
jpayne@68
|
1159 --long-help. The filters only work for little endian
|
|
jpayne@68
|
1160 instruction encoding but modern ARM processors using
|
|
jpayne@68
|
1161 big endian data access still use little endian
|
|
jpayne@68
|
1162 instruction encoding. So the help text was misleading.
|
|
jpayne@68
|
1163 In contrast, the PowerPC filter is only for big endian
|
|
jpayne@68
|
1164 32/64-bit PowerPC code. Little endian PowerPC would need
|
|
jpayne@68
|
1165 a separate filter.
|
|
jpayne@68
|
1166
|
|
jpayne@68
|
1167 - Added decompression support for the .lz (lzip) file format
|
|
jpayne@68
|
1168 version 0 and the original unextended version 1. It is
|
|
jpayne@68
|
1169 autodetected by default. See also the option --format on
|
|
jpayne@68
|
1170 the xz man page.
|
|
jpayne@68
|
1171
|
|
jpayne@68
|
1172 - Sandboxing enabled by default:
|
|
jpayne@68
|
1173 * Capsicum (FreeBSD)
|
|
jpayne@68
|
1174 * pledge(2) (OpenBSD)
|
|
jpayne@68
|
1175
|
|
jpayne@68
|
1176 * Scripts now support the .lz format using xz.
|
|
jpayne@68
|
1177
|
|
jpayne@68
|
1178 * A few new tests were added.
|
|
jpayne@68
|
1179
|
|
jpayne@68
|
1180 * The liblzma-specific tests are now supported in CMake-based
|
|
jpayne@68
|
1181 builds too ("make test").
|
|
jpayne@68
|
1182
|
|
jpayne@68
|
1183
|
|
jpayne@68
|
1184 5.3.5beta (2022-12-01)
|
|
jpayne@68
|
1185
|
|
jpayne@68
|
1186 * All fixes from 5.2.9.
|
|
jpayne@68
|
1187
|
|
jpayne@68
|
1188 * liblzma:
|
|
jpayne@68
|
1189
|
|
jpayne@68
|
1190 - Added new LZMA_FILTER_LZMA1EXT for raw encoder and decoder to
|
|
jpayne@68
|
1191 handle raw LZMA1 streams that don't have end of payload marker
|
|
jpayne@68
|
1192 (EOPM) alias end of stream (EOS) marker. It can be used in
|
|
jpayne@68
|
1193 filter chains, for example, with the x86 BCJ filter.
|
|
jpayne@68
|
1194
|
|
jpayne@68
|
1195 - Added lzma_str_to_filters(), lzma_str_from_filters(), and
|
|
jpayne@68
|
1196 lzma_str_list_filters() to make it easier for applications
|
|
jpayne@68
|
1197 to get custom compression options from a user and convert
|
|
jpayne@68
|
1198 it to an array of lzma_filter structures.
|
|
jpayne@68
|
1199
|
|
jpayne@68
|
1200 - Added lzma_filters_free().
|
|
jpayne@68
|
1201
|
|
jpayne@68
|
1202 - lzma_filters_update() can now be used with the multi-threaded
|
|
jpayne@68
|
1203 encoder (lzma_stream_encoder_mt()) to change the filter chain
|
|
jpayne@68
|
1204 after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH.
|
|
jpayne@68
|
1205
|
|
jpayne@68
|
1206 - In lzma_options_lzma, allow nice_len = 2 and 3 with the match
|
|
jpayne@68
|
1207 finders that require at least 3 or 4. Now it is internally
|
|
jpayne@68
|
1208 rounded up if needed.
|
|
jpayne@68
|
1209
|
|
jpayne@68
|
1210 - ARM64 filter was modified. It is still experimental.
|
|
jpayne@68
|
1211
|
|
jpayne@68
|
1212 - Fixed LTO build with Clang if -fgnuc-version=10 or similar
|
|
jpayne@68
|
1213 was used to make Clang look like GCC >= 10. Now it uses
|
|
jpayne@68
|
1214 __has_attribute(__symver__) which should be reliable.
|
|
jpayne@68
|
1215
|
|
jpayne@68
|
1216 * xz:
|
|
jpayne@68
|
1217
|
|
jpayne@68
|
1218 - --threads=+1 or -T+1 is now a way to put xz into multi-threaded
|
|
jpayne@68
|
1219 mode while using only one worker thread.
|
|
jpayne@68
|
1220
|
|
jpayne@68
|
1221 - In --lzma2=nice=NUMBER allow 2 and 3 with all match finders
|
|
jpayne@68
|
1222 now that liblzma handles it.
|
|
jpayne@68
|
1223
|
|
jpayne@68
|
1224 * Updated translations: Chinese (simplified), Korean, and Turkish.
|
|
jpayne@68
|
1225
|
|
jpayne@68
|
1226
|
|
jpayne@68
|
1227 5.3.4alpha (2022-11-15)
|
|
jpayne@68
|
1228
|
|
jpayne@68
|
1229 * All fixes from 5.2.7 and 5.2.8.
|
|
jpayne@68
|
1230
|
|
jpayne@68
|
1231 * liblzma:
|
|
jpayne@68
|
1232
|
|
jpayne@68
|
1233 - Minor improvements to the threaded decoder.
|
|
jpayne@68
|
1234
|
|
jpayne@68
|
1235 - Added CRC64 implementation that uses SSSE3, SSE4.1, and CLMUL
|
|
jpayne@68
|
1236 instructions on 32/64-bit x86 and E2K. On 32-bit x86 it's
|
|
jpayne@68
|
1237 not enabled unless --disable-assembler is used but then
|
|
jpayne@68
|
1238 the non-CLMUL code might be slower. Processor support is
|
|
jpayne@68
|
1239 detected at runtime so this is built by default on x86-64
|
|
jpayne@68
|
1240 and E2K. On these platforms, if compiler flags indicate
|
|
jpayne@68
|
1241 unconditional CLMUL support (-msse4.1 -mpclmul) then the
|
|
jpayne@68
|
1242 generic version is not built, making liblzma 8-9 KiB smaller
|
|
jpayne@68
|
1243 compared to having both versions included.
|
|
jpayne@68
|
1244
|
|
jpayne@68
|
1245 With extremely compressible files this can make decompression
|
|
jpayne@68
|
1246 up to twice as fast but with typical files 5 % improvement
|
|
jpayne@68
|
1247 is a more realistic expectation.
|
|
jpayne@68
|
1248
|
|
jpayne@68
|
1249 The CLMUL version is slower than the generic version with
|
|
jpayne@68
|
1250 tiny inputs (especially at 1-8 bytes per call, but up to
|
|
jpayne@68
|
1251 16 bytes). In normal use in xz this doesn't matter at all.
|
|
jpayne@68
|
1252
|
|
jpayne@68
|
1253 - Added an experimental ARM64 filter. This is *not* the final
|
|
jpayne@68
|
1254 version! Files created with this experimental version won't
|
|
jpayne@68
|
1255 be supported in the future versions! The filter design is
|
|
jpayne@68
|
1256 a compromise where improving one use case makes some other
|
|
jpayne@68
|
1257 cases worse.
|
|
jpayne@68
|
1258
|
|
jpayne@68
|
1259 - Added decompression support for the .lz (lzip) file format
|
|
jpayne@68
|
1260 version 0 and the original unextended version 1. See the
|
|
jpayne@68
|
1261 API docs of lzma_lzip_decoder() for details. Also
|
|
jpayne@68
|
1262 lzma_auto_decoder() supports .lz files.
|
|
jpayne@68
|
1263
|
|
jpayne@68
|
1264 - Building with --disable-threads --enable-small
|
|
jpayne@68
|
1265 is now thread-safe if the compiler supports
|
|
jpayne@68
|
1266 __attribute__((__constructor__))
|
|
jpayne@68
|
1267
|
|
jpayne@68
|
1268 * xz:
|
|
jpayne@68
|
1269
|
|
jpayne@68
|
1270 - Added support for OpenBSD's pledge(2) as a sandboxing method.
|
|
jpayne@68
|
1271
|
|
jpayne@68
|
1272 - Don't mention endianness for ARM and ARM-Thumb filters in
|
|
jpayne@68
|
1273 --long-help. The filters only work for little endian
|
|
jpayne@68
|
1274 instruction encoding but modern ARM processors using
|
|
jpayne@68
|
1275 big endian data access still use little endian
|
|
jpayne@68
|
1276 instruction encoding. So the help text was misleading.
|
|
jpayne@68
|
1277 In contrast, the PowerPC filter is only for big endian
|
|
jpayne@68
|
1278 32/64-bit PowerPC code. Little endian PowerPC would need
|
|
jpayne@68
|
1279 a separate filter.
|
|
jpayne@68
|
1280
|
|
jpayne@68
|
1281 - Added --experimental-arm64. This will be renamed once the
|
|
jpayne@68
|
1282 filter is finished. Files created with this experimental
|
|
jpayne@68
|
1283 filter will not be supported in the future!
|
|
jpayne@68
|
1284
|
|
jpayne@68
|
1285 - Added new fields to the output of xz --robot --info-memory.
|
|
jpayne@68
|
1286
|
|
jpayne@68
|
1287 - Added decompression support for the .lz (lzip) file format
|
|
jpayne@68
|
1288 version 0 and the original unextended version 1. It is
|
|
jpayne@68
|
1289 autodetected by default. See also the option --format on
|
|
jpayne@68
|
1290 the xz man page.
|
|
jpayne@68
|
1291
|
|
jpayne@68
|
1292 * Scripts now support the .lz format using xz.
|
|
jpayne@68
|
1293
|
|
jpayne@68
|
1294 * Build systems:
|
|
jpayne@68
|
1295
|
|
jpayne@68
|
1296 - New #defines in config.h: HAVE_ENCODER_ARM64,
|
|
jpayne@68
|
1297 HAVE_DECODER_ARM64, HAVE_LZIP_DECODER, HAVE_CPUID_H,
|
|
jpayne@68
|
1298 HAVE_FUNC_ATTRIBUTE_CONSTRUCTOR, HAVE_USABLE_CLMUL
|
|
jpayne@68
|
1299
|
|
jpayne@68
|
1300 - New configure options: --disable-clmul-crc,
|
|
jpayne@68
|
1301 --disable-microlzma, --disable-lzip-decoder, and
|
|
jpayne@68
|
1302 'pledge' is now an option in --enable-sandbox (but

jpayne@68
|
1303 it's autodetected by default anyway).
|
|
jpayne@68
|
1304
|
|
jpayne@68
|
1305 - INSTALL was updated to document the new configure options.
|
|
jpayne@68
|
1306
|
|
jpayne@68
|
1307 - PACKAGERS now lists also --disable-microlzma and
|
|
jpayne@68
|
1308 --disable-lzip-decoder as configure options that must
|
|
jpayne@68
|
1309 not be used in builds for non-embedded use.
|
|
jpayne@68
|
1310
|
|
jpayne@68
|
1311 * Tests:
|
|
jpayne@68
|
1312
|
|
jpayne@68
|
1313 - Fix some of the tests so that they skip instead of fail if
|
|
jpayne@68
|
1314 certain features have been disabled with configure options.
|
|
jpayne@68
|
1315 It's still not perfect.
|
|
jpayne@68
|
1316
|
|
jpayne@68
|
1317 - Other improvements to tests.
|
|
jpayne@68
|
1318
|
|
jpayne@68
|
1319 * Updated translations: Croatian, Finnish, Hungarian, Polish,
|
|
jpayne@68
|
1320 Romanian, Spanish, Swedish, and Ukrainian.

1323 5.3.3alpha (2022-08-22)
|
|
jpayne@68
|
1324
|
|
jpayne@68
|
1325 * All fixes from 5.2.6.
|
|
jpayne@68
|
1326
|
|
jpayne@68
|
1327 * liblzma:
|
|
jpayne@68
|
1328
|
|
jpayne@68
|
1329 - Fixed 32-bit build.
|
|
jpayne@68
|
1330
|
|
jpayne@68
|
1331 - Added threaded .xz decompressor lzma_stream_decoder_mt().
|
|
jpayne@68
|
1332 It can use multiple threads with .xz files that have multiple
|
|
jpayne@68
|
1333 Blocks with size information in Block Headers. The threaded
|
|
jpayne@68
|
1334 encoder in xz has always created such files.
|
|
jpayne@68
|
1335
|
|
jpayne@68
|
1336 Single-threaded encoder cannot store the size information in
|
|
jpayne@68
|
1337 Block Headers even if one used LZMA_FULL_FLUSH to create
|
|
jpayne@68
|
1338 multiple Blocks, so this threaded decoder cannot use multiple
|
|
jpayne@68
|
1339 threads with such files.
|
|
jpayne@68
|
1340
|
|
jpayne@68
|
1341 If there are multiple Streams (concatenated .xz files), one
|
|
jpayne@68
|
1342 Stream will be decompressed completely before starting the
|
|
jpayne@68
|
1343 next Stream.
|
|
jpayne@68
|
1344
|
|
jpayne@68
|
1345 - A new decoder flag LZMA_FAIL_FAST was added. It makes the
|
|
jpayne@68
|
1346 threaded decompressor report errors soon instead of first
|
|
jpayne@68
|
1347 flushing all pending data before the error location.
|
|
jpayne@68
|
1348
|
|
jpayne@68
|
1349 * xz:
|
|
jpayne@68
|
1350
|
|
jpayne@68
|
1351 - Using -T0 (--threads=0) will now use multi-threaded encoder
|
|
jpayne@68
|
1352 even on a single-core system. This is to ensure that output
|
|
jpayne@68
|
1353 from the same xz binary is identical on both single-core and
|
|
jpayne@68
|
1354 multi-core systems.
|
|
jpayne@68
|
1355
|
|
jpayne@68
|
1356 - A default soft memory usage limit is now used for compression
|
|
jpayne@68
|
1357 when -T0 is used and no explicit limit has been specified.
|
|
jpayne@68
|
1358 This soft limit is used to restrict the number of threads
|
|
jpayne@68
|
1359 but if the limit is exceeded with even one thread then xz
|
|
jpayne@68
|
1360 will continue with one thread using the multi-threaded
|
|
jpayne@68
|
1361 encoder and this limit is ignored. If the number of threads
|
|
jpayne@68
|
1362 is specified manually then no default limit will be used;
|
|
jpayne@68
|
1363 this affects only -T0.
|
|
jpayne@68
|
1364
|
|
jpayne@68
|
1365 This change helps on systems that have very many cores and
|
|
jpayne@68
|
1366 using all of them for xz makes no sense. Previously xz -T0
|
|
jpayne@68
|
1367 could run out of memory on such systems because it attempted
|
|
jpayne@68
|
1368 to reserve memory for too many threads.
|
|
jpayne@68
|
1369
|
|
jpayne@68
|
1370 This also helps with 32-bit builds which don't have a large
|
|
jpayne@68
|
1371 amount of address space that would be required for many
|
|
jpayne@68
|
1372 threads. The default limit is 1400 MiB on all 32-bit
|
|
jpayne@68
|
1373 platforms with -T0.
|
|
jpayne@68
|
1374
|
|
jpayne@68
|
1375 Now xz -T0 should just work. It might use too few threads
|
|
jpayne@68
|
1376 in some cases but at least it shouldn't easily run out of
|
|
jpayne@68
|
1377 memory. It's possible that this will be tweaked before 5.4.0.
|
|
jpayne@68
|
1378
|
|
jpayne@68
|
1379 - Changes to --memlimit-compress and --no-adjust:
|
|
jpayne@68
|
1380
|
|
jpayne@68
|
1381 In single-threaded mode, --memlimit-compress can make xz
|
|
jpayne@68
|
1382 scale down the LZMA2 dictionary size to meet the memory usage
|
|
jpayne@68
|
1383 limit. This obviously affects the compressed output. However,
|
|
jpayne@68
|
1384 if xz was in threaded mode, --memlimit-compress could make xz
|
|
jpayne@68
|
1385 reduce the number of threads but it wouldn't make xz switch
|
|
jpayne@68
|
1386 from multi-threaded mode to single-threaded mode or scale
|
|
jpayne@68
|
1387 down the LZMA2 dictionary size. This seemed illogical.
|
|
jpayne@68
|
1388
|
|
jpayne@68
|
1389 Now --memlimit-compress can make xz switch to single-threaded
|
|
jpayne@68
|
1390 mode if one thread in multi-threaded mode uses too much
|
|
jpayne@68
|
1391 memory. If memory usage is still too high, then the LZMA2
|
|
jpayne@68
|
1392 dictionary size can be scaled down too.
|
|
jpayne@68
|
1393
|
|
jpayne@68
|
1394 The option --no-adjust was also changed so that it no longer
|
|
jpayne@68
|
1395 prevents xz from scaling down the number of threads as that
|
|
jpayne@68
|
1396 doesn't affect compressed output (only performance). After
|
|
jpayne@68
|
1397 this commit --no-adjust only prevents adjustments that affect
|
|
jpayne@68
|
1398 compressed output, that is, with --no-adjust xz won't switch
|
|
jpayne@68
|
1399 from multithreaded mode to single-threaded mode and won't
|
|
jpayne@68
|
1400 scale down the LZMA2 dictionary size.
|
|
jpayne@68
|
1401
|
|
jpayne@68
|
1402 - Added a new option --memlimit-mt-decompress=LIMIT. This is
|
|
jpayne@68
|
1403 used to limit the number of decompressor threads (possibly
|
|
jpayne@68
|
1404 falling back to single-threaded mode) but it will never make
|
|
jpayne@68
|
1405 xz refuse to decompress a file. This has a system-specific
|
|
jpayne@68
|
1406 default value because without any limit xz could end up
|
|
jpayne@68
|
1407 allocating memory for the whole compressed input file, the
|
|
jpayne@68
|
1408 whole uncompressed output file, multiple thread-specific
|
|
jpayne@68
|
1409 decompressor instances and so on. Basically xz could
|
|
jpayne@68
|
1410 attempt to use an insane amount of memory even with fairly
|
|
jpayne@68
|
1411 common files.
|
|
jpayne@68
|
1412
|
|
jpayne@68
|
1413 The new option works together with the existing option
|
|
jpayne@68
|
1414 --memlimit-decompress=LIMIT. The old option sets a hard limit
|
|
jpayne@68
|
1415 that must not be exceeded (xz will refuse to decompress)
|
|
jpayne@68
|
1416 while the new option only restricts the number of threads.
|
|
jpayne@68
|
1417 If the limit set with --memlimit-mt-decompress is greater
|
|
jpayne@68
|
1418 than the limit set with --memlimit-compress, then the latter
|
|
jpayne@68
|
1419 value is used also for --memlimit-mt-decompress.
|
|
jpayne@68
|
1420
|
|
jpayne@68
|
1421 * Tests:
|
|
jpayne@68
|
1422
|
|
jpayne@68
|
1423 - Added a few more tests.
|
|
jpayne@68
|
1424
|
|
jpayne@68
|
1425 - Added tests/code_coverage.sh to create a code coverage report
|
|
jpayne@68
|
1426 of the tests.
|
|
jpayne@68
|
1427
|
|
jpayne@68
|
1428 * Build systems:
|
|
jpayne@68
|
1429
|
|
jpayne@68
|
1430 - Automake's parallel test harness is now used to make tests
|
|
jpayne@68
|
1431 finish faster.
|
|
jpayne@68
|
1432
|
|
jpayne@68
|
1433 - Added the CMake files to the distribution tarball. These were
|
|
jpayne@68
|
1434 supposed to be in 5.2.5 already.
|
|
jpayne@68
|
1435
|
|
jpayne@68
|
1436 - Added liblzma tests to the CMake build.
|
|
jpayne@68
|
1437
|
|
jpayne@68
|
1438 - Windows: Fix building of liblzma.dll with the included
|
|
jpayne@68
|
1439 Visual Studio project files.
|
|
jpayne@68
|
1440
|
|
jpayne@68
|
1441
|
|
jpayne@68
|
1442 5.3.2alpha (2021-10-28)
|
|
jpayne@68
|
1443
|
|
jpayne@68
|
1444 This release was made on short notice so that recent erofs-utils can
|
|
jpayne@68
|
1445 be built with LZMA support without needing a snapshot from xz.git.
|
|
jpayne@68
|
1446 Thus many pending things were not included, not even updated
|
|
jpayne@68
|
1447 translations (which would need to be updated for the new --list
|
|
jpayne@68
|
1448 strings anyway).
|
|
jpayne@68
|
1449
|
|
jpayne@68
|
1450 * All fixes from 5.2.5.
|
|
jpayne@68
|
1451
|
|
jpayne@68
|
1452 * xz:
|
|
jpayne@68
|
1453
|
|
jpayne@68
|
1454 - When copying metadata from the source file to the destination
|
|
jpayne@68
|
1455 file, don't try to set the group (GID) if it is already set
|
|
jpayne@68
|
1456 correctly. This avoids a failure on OpenBSD (and possibly on
|
|
jpayne@68
|
1457 a few other OSes) where files may get created so that their
|
|
jpayne@68
|
1458 group doesn't belong to the user, and fchown(2) can fail even
|
|
jpayne@68
|
1459 if it needs to do nothing.
|
|
jpayne@68
|
1460
|
|
jpayne@68
|
1461 - The --keep option now accepts symlinks, hardlinks, and
|
|
jpayne@68
|
1462 setuid, setgid, and sticky files. Previously this required
|
|
jpayne@68
|
1463 using --force.
|
|
jpayne@68
|
1464
|
|
jpayne@68
|
1465 - Split the long strings used in --list and --info-memory modes
|
|
jpayne@68
|
1466 to make them much easier for translators.
|
|
jpayne@68
|
1467
|
|
jpayne@68
|
1468 - If built with sandbox support and enabling the sandbox fails,
|
|
jpayne@68
|
1469 xz will now immediately exit with exit status of 1. Previously
|
|
jpayne@68
|
1470 it would only display a warning if -vv was used.
|
|
jpayne@68
|
1471
|
|
jpayne@68
|
1472 - Cap --memlimit-compress to 2000 MiB on MIPS32 because on
|
|
jpayne@68
|
1473 MIPS32 userspace processes are limited to 2 GiB of address
|
|
jpayne@68
|
1474 space.
|
|
jpayne@68
|
1475
|
|
jpayne@68
|
1476 * liblzma:
|
|
jpayne@68
|
1477
|
|
jpayne@68
|
1478 - Added lzma_microlzma_encoder() and lzma_microlzma_decoder().
|
|
jpayne@68
|
1479 The API is in lzma/container.h.
|
|
jpayne@68
|
1480
|
|
jpayne@68
|
1481 The MicroLZMA format is a raw LZMA stream (without end marker)
|
|
jpayne@68
|
1482 whose first byte (always 0x00) has been replaced with
|
|
jpayne@68
|
1483 bitwise-negation of the LZMA properties (lc/lp/pb). It was
|
|
jpayne@68
|
1484 created for use in EROFS but may be used in other contexts
|
|
jpayne@68
|
1485 as well where it is important to avoid wasting bytes for
|
|
jpayne@68
|
1486 stream headers or footers. The format is also supported by
|
|
jpayne@68
|
1487 XZ Embedded.
|
|
jpayne@68
|
1488
|
|
jpayne@68
|
1489 The MicroLZMA encoder API in liblzma can compress into a
|
|
jpayne@68
|
1490 fixed-sized output buffer so that as much data is compressed
|
|
jpayne@68
|
1491 as can be fit into the buffer while still creating a valid
|
|
jpayne@68
|
1492 MicroLZMA stream. This is needed for EROFS.
|
|
jpayne@68
|
1493
|
|
jpayne@68
|
1494 - Added fuzzing support.
|
|
jpayne@68
|
1495
|
|
jpayne@68
|
1496 - Support Intel Control-flow Enforcement Technology (CET) in
|
|
jpayne@68
|
1497 32-bit x86 assembly files.
|
|
jpayne@68
|
1498
|
|
jpayne@68
|
1499 - Visual Studio: Use non-standard _MSVC_LANG to detect C++
|
|
jpayne@68
|
1500 standard version in the lzma.h API header. It's used to
|
|
jpayne@68
|
1501 detect when "noexcept" can be used.
|
|
jpayne@68
|
1502
|
|
jpayne@68
|
1503 * Scripts:
|
|
jpayne@68
|
1504
|
|
jpayne@68
|
1505 - Fix exit status of xzdiff/xzcmp. Exit status could be 2 when
|
|
jpayne@68
|
1506 the correct value is 1.
|
|
jpayne@68
|
1507
|
|
jpayne@68
|
1508 - Fix exit status of xzgrep.
|
|
jpayne@68
|
1509
|
|
jpayne@68
|
1510 - Detect corrupt .bz2 files in xzgrep.
|
|
jpayne@68
|
1511
|
|
jpayne@68
|
1512 - Add zstd support to xzgrep and xzdiff/xzcmp.
|
|
jpayne@68
|
1513
|
|
jpayne@68
|
1514 - Fix less(1) version detection in xzless. It failed if the
|
|
jpayne@68
|
1515 version number from "less -V" contained a dot.
|
|
jpayne@68
|
1516
|
|
jpayne@68
|
1517 * Fix typos and technical issues in man pages.
|
|
jpayne@68
|
1518
|
|
jpayne@68
|
1519 * Build systems:
|
|
jpayne@68
|
1520
|
|
jpayne@68
|
1521 - Windows: Fix building of resource files when config.h isn't
|
|
jpayne@68
|
1522 used. CMake + Visual Studio can now build liblzma.dll.
|
|
jpayne@68
|
1523
|
|
jpayne@68
|
1524 - Various fixes to the CMake support. It might still need a few
|
|
jpayne@68
|
1525 more fixes even for liblzma-only builds.
|
|
jpayne@68
|
1526
|
|
jpayne@68
|
1527
|
|
jpayne@68
|
1528 5.3.1alpha (2018-04-29)
|
|
jpayne@68
|
1529
|
|
jpayne@68
|
1530 * All fixes from 5.2.4.
|
|
jpayne@68
|
1531
|
|
jpayne@68
|
1532 * Add lzma_file_info_decoder() into liblzma and use it in xz to
|
|
jpayne@68
|
1533 implement the --list feature.
|
|
jpayne@68
|
1534
|
|
jpayne@68
|
1535 * Capsicum sandbox support is enabled by default where available
|
|
jpayne@68
|
1536 (FreeBSD >= 10).
|
|
jpayne@68
|
1537
|
|
jpayne@68
|
1538
|
|
jpayne@68
|
1539 5.2.13 (2024-05-29)
|
|
jpayne@68
|
1540
|
|
jpayne@68
|
1541 * liblzma:
|
|
jpayne@68
|
1542
|
|
jpayne@68
|
1543 - lzma_index_append(): Fix an assertion failure that could be
|
|
jpayne@68
|
1544 triggered by a large unpadded_size argument. It was verified
|
|
jpayne@68
|
1545 that there was no other bug than the assertion failure.
|
|
jpayne@68
|
1546
|
|
jpayne@68
|
1547 - lzma_index_decoder() and lzma_index_buffer_decode(): Fix
|
|
jpayne@68
|
1548 a missing output pointer initialization (*i = NULL) if the
|
|
jpayne@68
|
1549 functions are called with invalid arguments. The API docs
|
|
jpayne@68
|
1550 say that such an initialization is always done. In practice
|
|
jpayne@68
|
1551 this matters very little because the problem can only occur
|
|
jpayne@68
|
1552 if the calling application has a bug and these functions
|
|
jpayne@68
|
1553 return LZMA_PROG_ERROR.
|
|
jpayne@68
|
1554
|
|
jpayne@68
|
1555 - Fix C standard conformance with function pointer types.
|
|

jpayne@68
|
1559 - Fix building with NVIDIA HPC SDK.
|
|
jpayne@68
|
1560
|
|
jpayne@68
|
1561 - Fix building with Windows Vista threads and --enable-small.
|
|
jpayne@68
|
1562 (CMake build doesn't support ENABLE_SMALL in XZ Utils 5.2.x.)
|
|
jpayne@68
|
1563
|
|
jpayne@68
|
1564 * xz:
|
|
jpayne@68
|
1565
|
|
jpayne@68
|
1566 - Fix a C standard conformance issue in --block-list parsing
|
|
jpayne@68
|
1567 (arithmetic on a null pointer).
|
|
jpayne@68
|
1568
|
|
jpayne@68
|
1569 - Fix a warning from GNU groff when processing the man page:
|
|
jpayne@68
|
1570 "warning: cannot select font 'CW'"
|
|
jpayne@68
|
1571
|
|
jpayne@68
|
1572 - Windows: Handle special files such as "con" or "nul". Earlier
|
|
jpayne@68
|
1573 the following wrote "foo" to the console and deleted the input
|
|
jpayne@68
|
1574 file "con_xz":
|
|
jpayne@68
|
1575
|
|
jpayne@68
|
1576 echo foo | xz > con_xz
|
|
jpayne@68
|
1577 xz --suffix=_xz --decompress con_xz
|
|
jpayne@68
|
1578
|
|
jpayne@68
|
1579 - Windows: Fix an issue that prevented reading from or writing
|
|
jpayne@68
|
1580 to non-terminal character devices like NUL.
|
|
jpayne@68
|
1581
|
|
jpayne@68
|
1582 * xzless:
|
|
jpayne@68
|
1583
|
|
jpayne@68
|
1584 - With "less" version 451 and later, use "||-" instead of "|-"
|
|
jpayne@68
|
1585 in the environment variable LESSOPEN. This way compressed
|
|
jpayne@68
|
1586 files that contain no uncompressed data are shown correctly
|
|
jpayne@68
|
1587 as empty.
|
|
jpayne@68
|
1588
|
|
jpayne@68
|
1589 - With "less" version 632 and later, use --show-preproc-errors
|
|
jpayne@68
|
1590 to make "less" show a warning on decompression errors.
|
|
jpayne@68
|
1591
|
|
jpayne@68
|
1592 * Build systems:
|
|
jpayne@68
|
1593
|
|
jpayne@68
|
1594 - Add a new line to liblzma.pc for MSYS2 (Windows):
|
|
jpayne@68
|
1595
|
|
jpayne@68
|
1596 Cflags.private: -DLZMA_API_STATIC
|
|
jpayne@68
|
1597
|
|
jpayne@68
|
1598 When compiling code that will link against static liblzma,
|
|
jpayne@68
|
1599 the LZMA_API_STATIC macro needs to be defined on Windows.
|
|
jpayne@68
|
1600
|
|
jpayne@68
|
1601 - Autotools (configure):
|
|
jpayne@68
|
1602
|
|
jpayne@68
|
1603 * Symbol versioning variant can now be overridden with
|
|
jpayne@68
|
1604 --enable-symbol-versions. Documentation in INSTALL was
|
|
jpayne@68
|
1605 updated to match.
|
|
jpayne@68
|
1606
|
|
jpayne@68
|
1607 - CMake:
|
|
jpayne@68
|
1608
|
|
jpayne@68
|
1609 * Fix a bug that prevented other projects from including
|
|
jpayne@68
|
1610 liblzma multiple times using find_package().
|
|
jpayne@68
|
1611
|
|
jpayne@68
|
1612 * Fix a bug where configuring CMake multiple times resulted
|
|
jpayne@68
|
1613 in HAVE_CLOCK_GETTIME and HAVE_CLOCK_MONOTONIC not being
|
|
jpayne@68
|
1614 defined.
|
|
jpayne@68
|
1615
|
|
jpayne@68
|
1616 * Fix the build with MinGW-w64-based Clang/LLVM 17.
|
|
jpayne@68
|
1617 llvm-windres now has more accurate GNU windres emulation
|
|
jpayne@68
|
1618 so the GNU windres workaround from 5.4.1 is needed with
|
|
jpayne@68
|
1619 llvm-windres version 17 too.
|
|
jpayne@68
|
1620
|
|
jpayne@68
|
1621 * The import library on Windows is now properly named
|
|
jpayne@68
|
1622 "liblzma.dll.a" instead of "libliblzma.dll.a"
|
|
jpayne@68
|
1623
|
|
jpayne@68
|
1624 * Add large file support by default for platforms that
|
|
jpayne@68
|
1625 need it to handle files larger than 2 GiB. This includes
|
|
jpayne@68
|
1626 MinGW-w64, even 64-bit builds.
|
|
jpayne@68
|
1627
|
|
jpayne@68
|
1628 * Linux on MicroBlaze is handled specially now. This
|
|
jpayne@68
|
1629 matches the changes made to the Autotools-based build
|
|
jpayne@68
|
1630 in XZ Utils 5.4.2 and 5.2.11.
|
|
jpayne@68
|
1631
|
|
jpayne@68
|
1632 * Disable symbol versioning on non-glibc Linux to match
|
|
jpayne@68
|
1633 what the Autotools build does. For example, symbol
|
|
jpayne@68
|
1634 versioning isn't enabled with musl.
|
|
jpayne@68
|
1635
|
|
jpayne@68
|
1636 * Symbol versioning variant can now be overridden by
|
|
jpayne@68
|
1637 setting SYMBOL_VERSIONING to "OFF", "generic", or
|
|
jpayne@68
|
1638 "linux".
|
|
jpayne@68
|
1639
|
|
jpayne@68
|
1640 * Documentation:
|
|
jpayne@68
|
1641
|
|
jpayne@68
|
1642 - Clarify the description of --disable-assembler in INSTALL.
|
|
jpayne@68
|
1643 The option only affects 32-bit x86 assembly usage.
|
|
jpayne@68
|
1644
|
|
jpayne@68
|
1645 - Don't install the TODO file as part of the documentation.
|
|
jpayne@68
|
1646 The file is out of date.
|
|
jpayne@68
|
1647
|
|
jpayne@68
|
1648 - Update home page URLs back to their old locations on
|
|
jpayne@68
|
1649 tukaani.org.
|
|
jpayne@68
|
1650
|
|
jpayne@68
|
1651 - Update maintainer info.

1654 5.2.12 (2023-05-04)
|
|
jpayne@68
|
1655
|
|
jpayne@68
|
1656 * Fixed a build system bug that prevented building liblzma as a
|
|
jpayne@68
|
1657 shared library when configured with --disable-threads. This bug
|
|
jpayne@68
|
1658 affected releases 5.2.6 to 5.2.11 and 5.4.0 to 5.4.2.
|
|
jpayne@68
|
1659
|
|
jpayne@68
|
1660 * Include <intrin.h> for Windows intrinsic functions where they are
|
|
jpayne@68
|
1661 needed. This fixed a bug that prevented building liblzma using
|
|
jpayne@68
|
1662 clang-cl on Windows.
|
|
jpayne@68
|
1663
|
|
jpayne@68
|
1664 * Minor update to the Croatian translation. The small change
|
|
jpayne@68
|
1665 applies to a string in both 5.2 and 5.4 branches.
|
|
jpayne@68
|
1666
|
|
jpayne@68
|
1667
|
|
jpayne@68
|
1668 5.2.11 (2023-03-18)
|
|
jpayne@68
|
1669
|
|
jpayne@68
|
1670 * Removed all possible cases of null pointer + 0. It is undefined
|
|
jpayne@68
|
1671 behavior in C99 and C17. This was detected by a sanitizer and had
|
|
jpayne@68
|
1672 not caused any known issues.
|
|
jpayne@68
|
1673
|
|
jpayne@68
|
1674 * Build systems:
|
|
jpayne@68
|
1675
|
|
jpayne@68
|
1676 - Added a workaround for building with GCC on MicroBlaze Linux.
|
|
jpayne@68
|
1677 GCC 12 on MicroBlaze doesn't support the __symver__ attribute
|
|
jpayne@68
|
1678 even though __has_attribute(__symver__) returns true. The
|
|
jpayne@68
|
1679 build is now done without the extra RHEL/CentOS 7 symbols
|
|
jpayne@68
|
1680 that were added in XZ Utils 5.2.7. The workaround only
|
|
jpayne@68
|
1681 applies to the Autotools build (not CMake).
|
|
jpayne@68
|
1682
|
|
jpayne@68
|
1683 - CMake: Ensure that the C compiler language is set to C99 or
|
|
jpayne@68
|
1684 a newer standard.
|
|
jpayne@68
|
1685
|
|
jpayne@68
|
1686 - CMake changes from XZ Utils 5.4.1:
|
|
jpayne@68
|
1687
|
|
jpayne@68
|
1688 * Added a workaround for a build failure with
|
|
jpayne@68
|
1689 windres from GNU binutils.
|
|
jpayne@68
|
1690
|
|
jpayne@68
|
1691 * Included the Windows resource files in the xz
|
|
jpayne@68
|
1692 and xzdec build rules.
|
|
jpayne@68
|
1693
|
|
jpayne@68
|
1694
|
|
jpayne@68
|
1695 5.2.10 (2022-12-13)
|
|
jpayne@68
|
1696
|
|
jpayne@68
|
1697 * xz: Don't modify argv[] when parsing the --memlimit* and
|
|
jpayne@68
|
1698 --block-list command line options. This fixes confusing
|
|
jpayne@68
|
1699 arguments in process listing (like "ps auxf").
|
|
jpayne@68
|
1700
|
|
jpayne@68
|
1701 * GNU/Linux only: Use __has_attribute(__symver__) to detect if
|
|
jpayne@68
|
1702 that attribute is supported. This fixes build on Mandriva where
|
|
jpayne@68
|
1703 Clang is patched to define __GNUC__ to 11 by default (instead
|
|
jpayne@68
|
1704 of 4 as used by Clang upstream).
|
|
jpayne@68
|
1705
|
|
jpayne@68
|
1706
|
|
jpayne@68
|
1707 5.2.9 (2022-11-30)
|
|
jpayne@68
|
1708
|
|
jpayne@68
|
1709 * liblzma:
|
|
jpayne@68
|
1710
|
|
jpayne@68
|
1711 - Fixed an infinite loop in LZMA encoder initialization
|
|
jpayne@68
|
1712 if dict_size >= 2 GiB. (The encoder only supports up
|
|
jpayne@68
|
1713 to 1536 MiB.)
|
|
jpayne@68
|
1714
|
|
jpayne@68
|
1715 - Fixed two cases of invalid free() that can happen if
|
|
jpayne@68
|
1716 a tiny allocation fails in encoder re-initialization
|
|
jpayne@68
|
1717 or in lzma_filters_update(). These bugs had some
|
|
jpayne@68
|
1718 similarities with the bug fixed in 5.2.7.
|
|
jpayne@68
|
1719
|
|
jpayne@68
|
1720 - Fixed lzma_block_encoder() not allowing the use of
|
|
jpayne@68
|
1721 LZMA_SYNC_FLUSH with lzma_code() even though it was
|
|
jpayne@68
|
1722 documented to be supported. The sync-flush code in
|
|
jpayne@68
|
1723 the Block encoder was already used internally via
|
|
jpayne@68
|
1724 lzma_stream_encoder(), so this was just a missing flag
|
|
jpayne@68
|
1725 in the lzma_block_encoder() API function.
|
|
jpayne@68
|
1726
|
|
jpayne@68
|
1727 - GNU/Linux only: Don't put symbol versions into static
|
|
jpayne@68
|
1728 liblzma as it breaks things in some cases (and even if
|
|
jpayne@68
|
1729 it didn't break anything, symbol versions in static
|
|
jpayne@68
|
1730 libraries are useless anyway). The downside of the fix
|
|
jpayne@68
|
1731 is that if the configure options --with-pic or --without-pic
|
|
jpayne@68
|
1732 are used then it's not possible to build both shared and
|
|
jpayne@68
|
1733 static liblzma at the same time on GNU/Linux anymore;
|
|
jpayne@68
|
1734 with those options --disable-static or --disable-shared
|
|
jpayne@68
|
1735 must be used too.
|
|
jpayne@68
|
1736
|
|
jpayne@68
|
1737 * New email address for bug reports is <xz@tukaani.org> which
|
|
jpayne@68
|
1738 forwards messages to Lasse Collin and Jia Tan.
|
|
jpayne@68
|
1739
|
|
jpayne@68
|
1740
|
|
jpayne@68
|
1741 5.2.8 (2022-11-13)
|
|
jpayne@68
|
1742
|
|
jpayne@68
|
1743 * xz:
|
|
jpayne@68
|
1744
|
|
jpayne@68
|
1745 - If xz cannot remove an input file when it should, this
|
|
jpayne@68
|
1746 is now treated as a warning (exit status 2) instead of
|
|
jpayne@68
|
1747 an error (exit status 1). This matches GNU gzip and it
|
|
jpayne@68
|
1748 is more logical as at that point the output file has
|
|
jpayne@68
|
1749 already been successfully closed.
|
|
jpayne@68
|
1750
|
|
jpayne@68
|
1751 - Fix handling of .xz files with an unsupported check type.
|
|
jpayne@68
|
1752 Previously such printed a warning message but then xz
|
|
jpayne@68
|
1753 behaved as if an error had occurred (didn't decompress,
|
|
jpayne@68
|
1754 exit status 1). Now a warning is printed, decompression
|
|
jpayne@68
|
1755 is done anyway, and exit status is 2. This used to work
|
|
jpayne@68
|
1756 slightly before 5.0.0. In practice this bug matters only
|
|
jpayne@68
|
1757 if xz has been built with some check types disabled. As
|
|
jpayne@68
|
1758 instructed in PACKAGERS, such builds should be done in
|
|
jpayne@68
|
1759 special situations only.
|
|
jpayne@68
|
1760
|
|
jpayne@68
|
1761 - Fix "xz -dc --single-stream tests/files/good-0-empty.xz"
|
|
jpayne@68
|
1762 which failed with "Internal error (bug)". That is,
|
|
jpayne@68
|
1763 --single-stream was broken if the first .xz stream in
|
|
jpayne@68
|
1764 the input file didn't contain any uncompressed data.
|
|
jpayne@68
|
1765
|
|
jpayne@68
|
1766 - Fix displaying file sizes in the progress indicator when
|
|
jpayne@68
|
1767 working in passthru mode and there are multiple input files.
|
|
jpayne@68
|
1768 Just like "gzip -cdf", "xz -cdf" works like "cat" when the
|
|
jpayne@68
|
1769 input file isn't a supported compressed file format. In
|
|
jpayne@68
|
1770 this case the file size counters weren't reset between
|
|
jpayne@68
|
1771 files so with multiple input files the progress indicator
|
|
jpayne@68
|
1772 displayed an incorrect (too large) value.
|
|
jpayne@68
|
1773
|
|
jpayne@68
|
1774 * liblzma:
|
|
jpayne@68
|
1775
|
|
jpayne@68
|
1776 - API docs in lzma/container.h:
|
|
jpayne@68
|
1777 * Update the list of decoder flags in the decoder
|
|
jpayne@68
|
1778 function docs.
|
|
jpayne@68
|
1779 * Explain LZMA_CONCATENATED behavior with .lzma files
|
|
jpayne@68
|
1780 in lzma_auto_decoder() docs.
|
|
jpayne@68
|
1781
|
|
jpayne@68
|
1782 - OpenBSD: Use HW_NCPUONLINE to detect the number of
|
|
jpayne@68
|
1783 available hardware threads in lzma_physmem().
|
|
jpayne@68
|
1784
|
|
jpayne@68
|
1785 - Fix use of wrong macro to detect x86 SSE2 support.
|
|
jpayne@68
|
1786 __SSE2_MATH__ was used with GCC/Clang but the correct
|
|
jpayne@68
|
1787 one is __SSE2__. The first one means that SSE2 is used
|
|
jpayne@68
|
1788 for floating point math which is irrelevant here.
|
|
jpayne@68
|
1789 The affected SSE2 code isn't used on x86-64 so this affects
|
|
jpayne@68
|
1790 only 32-bit x86 builds that use -msse2 without -mfpmath=sse
|
|
jpayne@68
|
1791 (there is no runtime detection for SSE2). It improves LZMA
|
|
jpayne@68
|
1792 compression speed (not decompression).
|
|
jpayne@68
|
1793
|
|
jpayne@68
|
1794 - Fix the build with Intel C compiler 2021 (ICC, not ICX)
|
|
jpayne@68
|
1795 on Linux. It defines __GNUC__ to 10 but doesn't support
|
|
jpayne@68
|
1796 the __symver__ attribute introduced in GCC 10.
|
|
jpayne@68
|
1797
|
|
jpayne@68
|
1798 * Scripts: Ignore warnings from xz by using --quiet --no-warn.
|
|
jpayne@68
|
1799 This is needed if the input .xz files use an unsupported
|
|
jpayne@68
|
1800 check type.
|
|
jpayne@68
|
1801
|
|
jpayne@68
|
1802 * Translations:
|
|
jpayne@68
|
1803
|
|
jpayne@68
|
1804 - Updated Croatian and Turkish translations.
|
|
jpayne@68
|
1805
|
|
jpayne@68
|
1806 - One new translations wasn't included because it needed
|
|
jpayne@68
|
1807 technical fixes. It will be in upcoming 5.4.0. No new
|
|
jpayne@68
|
1808 translations will be added to the 5.2.x branch anymore.
|
|
jpayne@68
|
1809
|
|
jpayne@68
|
1810 - Renamed the French man page translation file from
|
|
jpayne@68
|
1811 fr_FR.po to fr.po and thus also its install directory
|
|
jpayne@68
|
1812 (like /usr/share/man/fr_FR -> .../fr).
|
|
jpayne@68
|
1813
|
|
jpayne@68
|
1814 - Man page translations for upcoming 5.4.0 are now handled
|
|
jpayne@68
|
1815 in the Translation Project.
|
|
jpayne@68
|
1816
|
|
jpayne@68
|
1817 * Update doc/faq.txt a little so it's less out-of-date.
|
|
jpayne@68
|
1818
|
|
jpayne@68
|
1819
|
|
jpayne@68
|
1820 5.2.7 (2022-09-30)
|
|
jpayne@68
|
1821
|
|
jpayne@68
|
1822 * liblzma:
|
|
jpayne@68
|
1823
|
|
jpayne@68
|
1824 - Made lzma_filters_copy() to never modify the destination
|
|
jpayne@68
|
1825 array if an error occurs. lzma_stream_encoder() and
|
|
jpayne@68
|
1826 lzma_stream_encoder_mt() already assumed this. Before this
|
|
jpayne@68
|
1827 change, if a tiny memory allocation in lzma_filters_copy()
|
|
jpayne@68
|
1828 failed it would lead to a crash (invalid free() or invalid
|
|
jpayne@68
|
1829 memory reads) in the cleanup paths of these two encoder
|
|
jpayne@68
|
1830 initialization functions.
|
|
jpayne@68
|
1831
|
|
jpayne@68
|
1832 - Added missing integer overflow check to lzma_index_append().
|
|
jpayne@68
|
1833 This affects xz --list and other applications that decode
|
|
jpayne@68
|
1834 the Index field from .xz files using lzma_index_decoder().
|
|
jpayne@68
|
1835 Normal decompression of .xz files doesn't call this code
|
|
jpayne@68
|
1836 and thus most applications using liblzma aren't affected
|
|
jpayne@68
|
1837 by this bug.
|
|
jpayne@68
|
1838
|
|
jpayne@68
|
1839 - Single-threaded .xz decoder (lzma_stream_decoder()): If
|
|
jpayne@68
|
1840 lzma_code() returns LZMA_MEMLIMIT_ERROR it is now possible
|
|
jpayne@68
|
1841 to use lzma_memlimit_set() to increase the limit and continue
|
|
jpayne@68
|
1842 decoding. This was supposed to work from the beginning
|
|
jpayne@68
|
1843 but there was a bug. With other decoders (.lzma or
|
|
jpayne@68
|
1844 threaded .xz decoder) this already worked correctly.
|
|
jpayne@68
|
1845
|
|
jpayne@68
|
1846 - Fixed accumulation of integrity check type statistics in
|
|
jpayne@68
|
1847 lzma_index_cat(). This bug made lzma_index_checks() return
|
|
jpayne@68
|
1848 only the type of the integrity check of the last Stream
|
|
jpayne@68
|
1849 when multiple lzma_indexes were concatenated. Most
|
|
jpayne@68
|
1850 applications don't use these APIs but in xz it made
|
|
jpayne@68
|
1851 xz --list not list all check types from concatenated .xz
|
|
jpayne@68
|
1852 files. In xz --list --verbose only the per-file "Check:"
|
|
jpayne@68
|
1853 lines were affected and in xz --robot --list only the "file"
|
|
jpayne@68
|
1854 line was affected.
|
|
jpayne@68
|
1855
|
|
jpayne@68
|
1856 - Added ABI compatibility with executables that were linked
|
|
jpayne@68
|
1857 against liblzma in RHEL/CentOS 7 or other liblzma builds
|
|
jpayne@68
|
1858 that had copied the problematic patch from RHEL/CentOS 7
|
|
jpayne@68
|
1859 (xz-5.2.2-compat-libs.patch). For the details, see the
|
|
jpayne@68
|
1860 comment at the top of src/liblzma/validate_map.sh.
|
|
jpayne@68
|
1861
|
|
jpayne@68
|
1862 WARNING: This uses __symver__ attribute with GCC >= 10.
|
|
jpayne@68
|
1863 In other cases the traditional __asm__(".symver ...")
|
|
jpayne@68
|
1864 is used. Using link-time optimization (LTO, -flto) with
|
|
jpayne@68
|
1865 GCC versions older than 10 can silently result in
|
|
jpayne@68
|
1866 broken liblzma.so.5 (incorrect symbol versions)! If you
|
|
jpayne@68
|
1867 want to use -flto with GCC, you must use GCC >= 10.
|
|
jpayne@68
|
1868 LTO with Clang seems to work even with the traditional
|
|
jpayne@68
|
1869 __asm__(".symver ...") method.
|
|
jpayne@68
|
1870
|
|
jpayne@68
|
1871 * xzgrep: Fixed compatibility with old shells that break if
|
|
jpayne@68
|
1872 comments inside command substitutions have apostrophes (').
|
|
jpayne@68
|
1873 This problem was introduced in 5.2.6.
|
|
jpayne@68
|
1874
|
|
jpayne@68
|
1875 * Build systems:
|
|
jpayne@68
|
1876
|
|
jpayne@68
|
1877 - New #define in config.h: HAVE_SYMBOL_VERSIONS_LINUX
|
|
jpayne@68
|
1878
|
|
jpayne@68
|
1879 - Windows: Fixed liblzma.dll build with Visual Studio project
|
|
jpayne@68
|
1880 files. It broke in 5.2.6 due to a change that was made to
|
|
jpayne@68
|
1881 improve CMake support.
|
|
jpayne@68
|
1882
|
|
jpayne@68
|
1883 - Windows: Building liblzma with UNICODE defined should now
|
|
jpayne@68
|
1884 work.
|
|
jpayne@68
|
1885
|
|
jpayne@68
|
1886 - CMake files are now actually included in the release tarball.
|
|
jpayne@68
|
1887 They should have been in 5.2.5 already.
|
|
jpayne@68
|
1888
|
|
jpayne@68
|
1889 - Minor CMake fixes and improvements.
|
|
jpayne@68
|
1890
|
|
jpayne@68
|
1891 * Added a new translation: Turkish
|
|
jpayne@68
|
1892
|
|
jpayne@68
|
1893
|
|
jpayne@68
|
1894 5.2.6 (2022-08-12)
|
|
jpayne@68
|
1895
|
|
jpayne@68
|
1896 * xz:
|
|
jpayne@68
|
1897
|
|
jpayne@68
|
1898 - The --keep option now accepts symlinks, hardlinks, and
|
|
jpayne@68
|
1899 setuid, setgid, and sticky files. Previously this required
|
|
jpayne@68
|
1900 using --force.
|
|
jpayne@68
|
1901
|
|
jpayne@68
|
1902 - When copying metadata from the source file to the destination
|
|
jpayne@68
|
1903 file, don't try to set the group (GID) if it is already set
|
|
jpayne@68
|
1904 correctly. This avoids a failure on OpenBSD (and possibly on
|
|
jpayne@68
|
1905 a few other OSes) where files may get created so that their
|
|
jpayne@68
|
1906 group doesn't belong to the user, and fchown(2) can fail even
|
|
jpayne@68
|
1907 if it needs to do nothing.
|
|
jpayne@68
|
1908
|
|
jpayne@68
|
1909 - Cap --memlimit-compress to 2000 MiB instead of 4020 MiB on
|
|
jpayne@68
|
1910 MIPS32 because on MIPS32 userspace processes are limited
|
|
jpayne@68
|
1911 to 2 GiB of address space.
|
|
jpayne@68
|
1912
|
|
jpayne@68
|
1913 * liblzma:
|
|
jpayne@68
|
1914
|
|
jpayne@68
|
1915 - Fixed a missing error-check in the threaded encoder. If a
|
|
jpayne@68
|
1916 small memory allocation fails, a .xz file with an invalid
|
|
jpayne@68
|
1917 Index field would be created. Decompressing such a file would
|
|
jpayne@68
|
1918 produce the correct output but result in an error at the end.
|
|
jpayne@68
|
1919 Thus this is a "mild" data corruption bug. Note that while
|
|
jpayne@68
|
1920 a failed memory allocation can trigger the bug, it cannot
|
|
jpayne@68
|
1921 cause invalid memory access.
|
|
jpayne@68
|
1922
|
|
jpayne@68
|
1923 - The decoder for .lzma files now supports files that have
|
|
jpayne@68
|
1924 uncompressed size stored in the header and still use the
|
|
jpayne@68
|
1925 end of payload marker (end of stream marker) at the end
|
|
jpayne@68
|
1926 of the LZMA stream. Such files are rare but, according to
|
|
jpayne@68
|
1927 the documentation in LZMA SDK, they are valid.
|
|
jpayne@68
|
1928 doc/lzma-file-format.txt was updated too.
|
|
jpayne@68
|
1929
|
|
jpayne@68
|
1930 - Improved 32-bit x86 assembly files:
|
|
jpayne@68
|
1931 * Support Intel Control-flow Enforcement Technology (CET)
|
|
jpayne@68
|
1932 * Use non-executable stack on FreeBSD.
|
|
jpayne@68
|
1933
|
|
jpayne@68
|
1934 - Visual Studio: Use non-standard _MSVC_LANG to detect C++
|
|
jpayne@68
|
1935 standard version in the lzma.h API header. It's used to
|
|
jpayne@68
|
1936 detect when "noexcept" can be used.
|
|
jpayne@68
|
1937
|
|
jpayne@68
|
1938 * xzgrep:
|
|
jpayne@68
|
1939
|
|
jpayne@68
|
1940 - Fixed arbitrary command injection via a malicious filename
|
|
jpayne@68
|
1941 (CVE-2022-1271, ZDI-CAN-16587). A standalone patch for
|
|
jpayne@68
|
1942 this was released to the public on 2022-04-07. A slight
|
|
jpayne@68
|
1943 robustness improvement has been made since then and, if
|
|
jpayne@68
|
1944 using GNU or *BSD grep, a new faster method is now used
|
|
jpayne@68
|
1945 that doesn't use the old sed-based construct at all. This
|
|
jpayne@68
|
1946 also fixes bad output with GNU grep >= 3.5 (2020-09-27)
|
|
jpayne@68
|
1947 when xzgrepping binary files.
|
|
jpayne@68
|
1948
|
|
jpayne@68
|
1949 This vulnerability was discovered by:
|
|
jpayne@68
|
1950 cleemy desu wayo working with Trend Micro Zero Day Initiative
|
|
jpayne@68
|
1951
|
|
jpayne@68
|
1952 - Fixed detection of corrupt .bz2 files.
|
|
jpayne@68
|
1953
|
|
jpayne@68
|
1954 - Improved error handling to fix exit status in some situations
|
|
jpayne@68
|
1955 and to fix handling of signals: in some situations a signal
|
|
jpayne@68
|
1956 didn't make xzgrep exit when it clearly should have. It's
|
|
jpayne@68
|
1957 possible that the signal handling still isn't quite perfect
|
|
jpayne@68
|
1958 but hopefully it's good enough.
|
|
jpayne@68
|
1959
|
|
jpayne@68
|
1960 - Documented exit statuses on the man page.
|
|
jpayne@68
|
1961
|
|
jpayne@68
|
1962 - xzegrep and xzfgrep now use "grep -E" and "grep -F" instead
|
|
jpayne@68
|
1963 of the deprecated egrep and fgrep commands.
|
|
jpayne@68
|
1964
|
|
jpayne@68
|
1965 - Fixed parsing of the options -E, -F, -G, -P, and -X. The
|
|
jpayne@68
|
1966 problem occurred when multiple options were specified in
|
|
jpayne@68
|
1967 a single argument, for example,
|
|
jpayne@68
|
1968
|
|
jpayne@68
|
1969 echo foo | xzgrep -Fe foo
|
|
jpayne@68
|
1970
|
|
jpayne@68
|
1971 treated foo as a filename because -Fe wasn't correctly
|
|
jpayne@68
|
1972 split into -F -e.
|
|
jpayne@68
|
1973
|
|
jpayne@68
|
1974 - Added zstd support.
|
|
jpayne@68
|
1975
|
|
jpayne@68
|
1976 * xzdiff/xzcmp:
|
|
jpayne@68
|
1977
|
|
jpayne@68
|
1978 - Fixed wrong exit status. Exit status could be 2 when the
|
|
jpayne@68
|
1979 correct value is 1.
|
|
jpayne@68
|
1980
|
|
jpayne@68
|
1981 - Documented on the man page that exit status of 2 is used
|
|
jpayne@68
|
1982 for decompression errors.
|
|
jpayne@68
|
1983
|
|
jpayne@68
|
1984 - Added zstd support.
|
|
jpayne@68
|
1985
|
|
jpayne@68
|
1986 * xzless:
|
|
jpayne@68
|
1987
|
|
jpayne@68
|
1988 - Fix less(1) version detection. It failed if the version number
|
|
jpayne@68
|
1989 from "less -V" contained a dot.
|
|
jpayne@68
|
1990
|
|
jpayne@68
|
1991 * Translations:
|
|
jpayne@68
|
1992
|
|
jpayne@68
|
1993 - Added new translations: Catalan, Croatian, Esperanto,
|
|
jpayne@68
|
1994 Korean, Portuguese, Romanian, Serbian, Spanish, Swedish,
|
|
jpayne@68
|
1995 and Ukrainian
|
|
jpayne@68
|
1996
|
|
jpayne@68
|
1997 - Updated the Brazilian Portuguese translation.
|
|
jpayne@68
|
1998
|
|
jpayne@68
|
1999 - Added French man page translation. This and the existing
|
|
jpayne@68
|
2000 German translation aren't complete anymore because the
|
|
jpayne@68
|
2001 English man pages got a few updates and the translators
|
|
jpayne@68
|
2002 weren't reached so that they could update their work.
|
|
jpayne@68
|
2003
|
|
jpayne@68
|
2004 * Build systems:
|
|
jpayne@68
|
2005
|
|
jpayne@68
|
2006 - Windows: Fix building of resource files when config.h isn't
|
|
jpayne@68
|
2007 used. CMake + Visual Studio can now build liblzma.dll.
|
|
jpayne@68
|
2008
|
|
jpayne@68
|
2009 - Various fixes to the CMake support. Building static or shared
|
|
jpayne@68
|
2010 liblzma should work fine in most cases. In contrast, building
|
|
jpayne@68
|
2011 the command line tools with CMake is still clearly incomplete
|
|
jpayne@68
|
2012 and experimental and should be used for testing only.
|
|
jpayne@68
|
2013
|
|
jpayne@68
|
2014
|
|
jpayne@68
|
2015 5.2.5 (2020-03-17)
|
|
jpayne@68
|
2016
|
|
jpayne@68
|
2017 * liblzma:
|
|
jpayne@68
|
2018
|
|
jpayne@68
|
2019 - Fixed several C99/C11 conformance bugs. Now the code is clean
|
|
jpayne@68
|
2020 under gcc/clang -fsanitize=undefined. Some of these changes
|
|
jpayne@68
|
2021 might have a negative effect on performance with old GCC
|
|
jpayne@68
|
2022 versions or compilers other than GCC and Clang. The configure
|
|
jpayne@68
|
2023 option --enable-unsafe-type-punning can be used to (mostly)
|
|
jpayne@68
|
2024 restore the old behavior but it shouldn't normally be used.
|
|
jpayne@68
|
2025
|
|
jpayne@68
|
2026 - Improved API documentation of lzma_properties_decode().
|
|
jpayne@68
|
2027
|
|
jpayne@68
|
2028 - Added a very minor encoder speed optimization.
|
|
jpayne@68
|
2029
|
|
jpayne@68
|
2030 * xz:
|
|
jpayne@68
|
2031
|
|
jpayne@68
|
2032 - Fixed a crash in "xz -dcfv not_an_xz_file". All four options
|
|
jpayne@68
|
2033 were required to trigger it. The crash occurred in the
|
|
jpayne@68
|
2034 progress indicator code when xz was in passthru mode where
|
|
jpayne@68
|
2035 xz works like "cat".
|
|
jpayne@68
|
2036
|
|
jpayne@68
|
2037 - Fixed an integer overflow with 32-bit off_t. It could happen
|
|
jpayne@68
|
2038 when decompressing a file that has a long run of zero bytes
|
|
jpayne@68
|
2039 which xz would try to write as a sparse file. Since the build
|
|
jpayne@68
|
2040 system enables large file support by default, off_t is
|
|
jpayne@68
|
2041 normally 64-bit even on 32-bit systems.
|
|
jpayne@68
|
2042
|
|
jpayne@68
|
2043 - Fixes for --flush-timeout:
|
|
jpayne@68
|
2044 * Fix semi-busy-waiting.
|
|
jpayne@68
|
2045 * Avoid unneeded flushes when no new input has arrived
|
|
jpayne@68
|
2046 since the previous flush was completed.
|
|
jpayne@68
|
2047
|
|
jpayne@68
|
2048 - Added a special case for 32-bit xz: If --memlimit-compress is
|
|
jpayne@68
|
2049 used to specify a limit that exceeds 4020 MiB, the limit will
|
|
jpayne@68
|
2050 be set to 4020 MiB. The values "0" and "max" aren't affected
|
|
jpayne@68
|
2051 by this and neither is decompression. This hack can be
|
|
jpayne@68
|
2052 helpful when a 32-bit xz has access to 4 GiB address space
|
|
jpayne@68
|
2053 but the specified memlimit exceeds 4 GiB. This can happen
|
|
jpayne@68
|
2054 e.g. with some scripts.
|
|
jpayne@68
|
2055
|
|
jpayne@68
|
2056 - Capsicum sandbox is now enabled by default where available

|
2057 (FreeBSD >= 10). The sandbox debug messages (xz -vv) were
|
|
jpayne@68
|
2058 removed since they seemed to be more annoying than useful.
|
|
jpayne@68
|
2059
|
|
jpayne@68
|
2060 - DOS build now requires DJGPP 2.05 instead of 2.04beta.
|
|
jpayne@68
|
2061 A workaround for a locale problem with DJGPP 2.05 was added.
|
|
jpayne@68
|
2062
|
|
jpayne@68
|
2063 * xzgrep and other scripts:
|
|
jpayne@68
|
2064
|
|
jpayne@68
|
2065 - Added a configure option --enable-path-for-scripts=PREFIX.
|
|
jpayne@68
|
2066 It is disabled by default except on Solaris where the default
|
|
jpayne@68
|
2067 is /usr/xpg4/bin. See INSTALL for details.
|
|
jpayne@68
|
2068
|
|
jpayne@68
|
2069 - Added a workaround for a POSIX shell detection problem on
|
|
jpayne@68
|
2070 Solaris.
|
|
jpayne@68
|
2071
|
|
jpayne@68
|
2072 * Build systems:
|
|
jpayne@68
|
2073
|
|
jpayne@68
|
2074 - Added preliminary build instructions for z/OS. See INSTALL
|
|
jpayne@68
|
2075 section 1.2.9.
|
|
jpayne@68
|
2076
|
|
jpayne@68
|
2077 - Experimental CMake support was added. It should work to build
|
|
jpayne@68
|
2078 static liblzma on a few operating systems. It may or may not
|
|
jpayne@68
|
2079 work to build shared liblzma. On some platforms it can build
|
|
jpayne@68
|
2080 xz and xzdec too but those are only for testing. See the
|
|
jpayne@68
|
2081 comment in the beginning of CMakeLists.txt for details.
|
|
jpayne@68
|
2082
|
|
jpayne@68
|
2083 - Visual Studio project files were updated.
|
|
jpayne@68
|
2084 WindowsTargetPlatformVersion was removed from VS2017 files
|
|
jpayne@68
|
2085 and set to "10.0" in the added VS2019 files. In the future
|
|
jpayne@68
|
2086 the VS project files will be removed when CMake support is
|
|
jpayne@68
|
2087 good enough.
|
|
jpayne@68
|
2088
|
|
jpayne@68
|
2089 - New #defines in config.h: HAVE___BUILTIN_ASSUME_ALIGNED,
|
|
jpayne@68
|
2090 HAVE___BUILTIN_BSWAPXX, and TUKLIB_USE_UNSAFE_TYPE_PUNNING.
|
|
jpayne@68
|
2091
|
|
jpayne@68
|
2092 - autogen.sh has a new optional dependency on po4a and a new
|
|
jpayne@68
|
2093 option --no-po4a to skip that step. This matters only if one
|
|
jpayne@68
|
2094 wants to remake the build files. po4a is used to update the
|
|
jpayne@68
|
2095 translated man pages but as long as the man pages haven't
|
|
jpayne@68
|
2096 been modified, there's nothing to update and one can use
|
|
jpayne@68
|
2097 --no-po4a to avoid the dependency on po4a.
|
|
jpayne@68
|
2098
|
|
jpayne@68
|
2099 * Translations:
|
|
jpayne@68
|
2100
|
|
jpayne@68
|
2101 - XZ Utils translations are now handled by the Translation
|
|
jpayne@68
|
2102 Project: https://translationproject.org/domain/xz.html
|
|
jpayne@68
|
2103
|
|
jpayne@68
|
2104 - All man pages are now included in German too.
|
|
jpayne@68
|
2105
|
|
jpayne@68
|
2106 - New xz translations: Brazilian Portuguese, Finnish,
|
|
jpayne@68
|
2107 Hungarian, Chinese (simplified), Chinese (traditional),
|
|
jpayne@68
|
2108 and Danish (partial translation)
|
|
jpayne@68
|
2109
|
|
jpayne@68
|
2110 - Updated xz translations: French, German, Italian, and Polish
|
|
jpayne@68
|
2111
|
|
jpayne@68
|
2112 - Unfortunately a few new xz translations weren't included due
|
|
jpayne@68
|
2113 to technical problems like too long lines in --help output or
|
|
jpayne@68
|
2114 misaligned column headings in tables. In the future, many of
|
|
jpayne@68
|
2115 these strings will be split and e.g. the table column
|
|
jpayne@68
|
2116 alignment will be handled in software. This should make the
|
|
jpayne@68
|
2117 strings easier to translate.
|
|
jpayne@68
|
2118
|
|
jpayne@68
|
2119
|
|
jpayne@68
|
2120 5.2.4 (2018-04-29)
|
|
jpayne@68
|
2121
|
|
jpayne@68
|
2122 * liblzma:
|
|
jpayne@68
|
2123
|
|
jpayne@68
|
2124 - Allow 0 as memory usage limit instead of returning
|
|
jpayne@68
|
2125 LZMA_PROG_ERROR. Now 0 is treated as if 1 byte was specified,
|
|
jpayne@68
|
2126 which effectively is the same as 0.
|
|
jpayne@68
|
2127
|
|
jpayne@68
|
2128 - Use "noexcept" keyword instead of "throw()" in the public
|
|
jpayne@68
|
2129 headers when a C++11 (or newer standard) compiler is used.
|
|
jpayne@68
|
2130
|
|
jpayne@68
|
2131 - Added a portability fix for recent Intel C Compilers.
|
|
jpayne@68
|
2132
|
|
jpayne@68
|
2133 - Microsoft Visual Studio build files have been moved under
|
|
jpayne@68
|
2134 windows/vs2013 and windows/vs2017.
|
|
jpayne@68
|
2135
|
|
jpayne@68
|
2136 * xz:
|
|
jpayne@68
|
2137
|
|
jpayne@68
|
2138 - Fix "xz --list --robot missing_or_bad_file.xz" which would
|
|
jpayne@68
|
2139 try to print an uninitialized string and thus produce garbage
|
|
jpayne@68
|
2140 output. Since the exit status is non-zero, most uses of such
|
|
jpayne@68
|
2141 a command won't try to interpret the garbage output.
|
|
jpayne@68
|
2142
|
|
jpayne@68
|
2143 - "xz --list foo.xz" could print "Internal error (bug)" in a
|
|
jpayne@68
|
2144 corner case where a specific memory usage limit had been set.
|
|
jpayne@68
|
2145
|
|
jpayne@68
|
2146
|
|
jpayne@68
|
2147 5.2.3 (2016-12-30)
|
|
jpayne@68
|
2148
|
|
jpayne@68
|
2149 * xz:
|
|
jpayne@68
|
2150
|
|
jpayne@68
|
2151 - Always close a file before trying to delete it to avoid
|
|
jpayne@68
|
2152 problems on some operating system and file system combinations.
|
|
jpayne@68
|
2153
|
|
jpayne@68
|
2154 - Fixed copying of file timestamps on Windows.
|
|
jpayne@68
|
2155
|
|
jpayne@68
|
2156 - Added experimental (disabled by default) sandbox support using
|
|
jpayne@68
|
2157 Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL.
|
|
jpayne@68
|
2158
|
|
jpayne@68
|
2159 * C99/C11 conformance fixes to liblzma. The issues affected at least
|
|
jpayne@68
|
2160 some builds using link-time optimizations.
|
|
jpayne@68
|
2161
|
|
jpayne@68
|
2162 * Fixed bugs in the rarely-used function lzma_index_dup().
|
|
jpayne@68
|
2163
|
|
jpayne@68
|
2164 * Use of external SHA-256 code is now disabled by default.
|
|
jpayne@68
|
2165 It can still be enabled by passing --enable-external-sha256
|
|
jpayne@68
|
2166 to configure. The reasons to disable it by default (see INSTALL
|
|
jpayne@68
|
2167 for more details):
|
|
jpayne@68
|
2168
|
|
jpayne@68
|
2169 - Some OS-specific SHA-256 implementations conflict with
|
|
jpayne@68
|
2170 OpenSSL and cause problems in programs that link against both
|
|
jpayne@68
|
2171 liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0
|
|
jpayne@68
|
2172 are affected.
|
|
jpayne@68
|
2173
|
|
jpayne@68
|
2174 - The internal SHA-256 is faster than the SHA-256 code in
|
|
jpayne@68
|
2175 some operating systems.
|
|
jpayne@68
|
2176
|
|
jpayne@68
|
2177 * Changed CPU core count detection to use sched_getaffinity() on
|
|
jpayne@68
|
2178 GNU/Linux and GNU/kFreeBSD.
|
|
jpayne@68
|
2179
|
|
jpayne@68
|
2180 * Fixes to the build-system and xz to make xz buildable even when
|
|
jpayne@68
|
2181 encoders, decoders, or threading have been disabled from libilzma
|
|
jpayne@68
|
2182 using configure options. These fixes added two new #defines to
|
|
jpayne@68
|
2183 config.h: HAVE_ENCODERS and HAVE_DECODERS.
|
|
jpayne@68
|
2184
|
|
jpayne@68
|
2185
|
|
jpayne@68
|
2186 5.2.2 (2015-09-29)
|
|
jpayne@68
|
2187
|
|
jpayne@68
|
2188 * Fixed bugs in QNX-specific code.
|
|
jpayne@68
|
2189
|
|
jpayne@68
|
2190 * Omitted the use of pipe2() even if it is available to avoid
|
|
jpayne@68
|
2191 portability issues with some old Linux and glibc combinations.
|
|
jpayne@68
|
2192
|
|
jpayne@68
|
2193 * Updated German translation.
|
|
jpayne@68
|
2194
|
|
jpayne@68
|
2195 * Added project files to build static and shared liblzma (not the
|
|
jpayne@68
|
2196 whole XZ Utils) with Visual Studio 2013 update 2 or later.
|
|
jpayne@68
|
2197
|
|
jpayne@68
|
2198 * Documented that threaded decompression hasn't been implemented
|
|
jpayne@68
|
2199 yet. A 5.2.0 NEWS entry describing multi-threading support had
|
|
jpayne@68
|
2200 incorrectly said "decompression" when it should have said
|
|
jpayne@68
|
2201 "compression".
|
|
jpayne@68
|
2202
|
|
jpayne@68
|
2203
|
|
jpayne@68
|
2204 5.2.1 (2015-02-26)
|
|
jpayne@68
|
2205
|
|
jpayne@68
|
2206 * Fixed a compression-ratio regression in fast mode of LZMA1 and
|
|
jpayne@68
|
2207 LZMA2. The bug is present in 5.1.4beta and 5.2.0 releases.
|
|
jpayne@68
|
2208
|
|
jpayne@68
|
2209 * Fixed a portability problem in xz that affected at least OpenBSD.
|
|
jpayne@68
|
2210
|
|
jpayne@68
|
2211 * Fixed xzdiff to be compatible with FreeBSD's mktemp which differs
|
|
jpayne@68
|
2212 from most other mktemp implementations.
|
|
jpayne@68
|
2213
|
|
jpayne@68
|
2214 * Changed CPU core count detection to use cpuset_getaffinity() on
|
|
jpayne@68
|
2215 FreeBSD.
|
|
jpayne@68
|
2216
|
|
jpayne@68
|
2217
|
|
jpayne@68
|
2218 5.2.0 (2014-12-21)
|
|
jpayne@68
|
2219
|
|
jpayne@68
|
2220 Since 5.1.4beta:
|
|
jpayne@68
|
2221
|
|
jpayne@68
|
2222 * All fixes from 5.0.8
|
|
jpayne@68
|
2223
|
|
jpayne@68
|
2224 * liblzma: Fixed lzma_stream_encoder_mt_memusage() when a preset
|
|
jpayne@68
|
2225 was used.
|
|
jpayne@68
|
2226
|
|
jpayne@68
|
2227 * xzdiff: If mktemp isn't installed, mkdir will be used as
|
|
jpayne@68
|
2228 a fallback to create a temporary directory. Installing mktemp
|
|
jpayne@68
|
2229 is still recommended.
|
|
jpayne@68
|
2230
|
|
jpayne@68
|
2231 * Updated French, German, Italian, Polish, and Vietnamese
|
|
jpayne@68
|
2232 translations.
|
|
jpayne@68
|
2233
|

jpayne@68
|
2234 Summary of fixes and new features added in the 5.1.x development
|
|
jpayne@68
|
2235 releases:
|
|
jpayne@68
|
2236
|
|
jpayne@68
|
2237 * liblzma:
|
|
jpayne@68
|
2238
|
|
jpayne@68
|
2239 - Added support for multi-threaded compression. See the
|
|
jpayne@68
|
2240 lzma_mt structure, lzma_stream_encoder_mt(), and
|
|
jpayne@68
|
2241 lzma_stream_encoder_mt_memusage() in <lzma/container.h>,
|
|
jpayne@68
|
2242 lzma_get_progress() in <lzma/base.h>, and lzma_cputhreads()
|
|
jpayne@68
|
2243 in <lzma/hardware.h> for details.
|
|
jpayne@68
|
2244
|
|
jpayne@68
|
2245 - Made the uses of lzma_allocator const correct.
|
|
jpayne@68
|
2246
|
|
jpayne@68
|
2247 - Added lzma_block_uncomp_encode() to create uncompressed
|
|
jpayne@68
|
2248 .xz Blocks using LZMA2 uncompressed chunks.
|
|
jpayne@68
|
2249
|
|
jpayne@68
|
2250 - Added support for LZMA_IGNORE_CHECK.
|
|
jpayne@68
|
2251
|
|
jpayne@68
|
2252 - A few speed optimizations were made.
|
|
jpayne@68
|
2253
|
|
jpayne@68
|
2254 - Added support for symbol versioning. It is enabled by default
|
|
jpayne@68
|
2255 on GNU/Linux, other GNU-based systems, and FreeBSD.
|
|
jpayne@68
|
2256
|
|
jpayne@68
|
2257 - liblzma (not the whole XZ Utils) should now be buildable
|
|
jpayne@68
|
2258 with MSVC 2013 update 2 or later using windows/config.h.
|
|
jpayne@68
|
2259
|
|
jpayne@68
|
2260 * xz:
|
|
jpayne@68
|
2261
|
|
jpayne@68
|
2262 - Fixed a race condition in the signal handling. It was
|
|
jpayne@68
|
2263 possible that e.g. the first SIGINT didn't make xz exit
|
|
jpayne@68
|
2264 if reading or writing blocked and one had bad luck. The fix
|
|
jpayne@68
|
2265 is non-trivial, so as of writing it is unknown if it will be
|
|
jpayne@68
|
2266 backported to the v5.0 branch.
|
|
jpayne@68
|
2267
|
|
jpayne@68
|
2268 - Multi-threaded compression can be enabled with the
|
|
jpayne@68
|
2269 --threads (-T) option.
|
|
jpayne@68
|
2270 [Fixed: This originally said "decompression".]
|
|
jpayne@68
|
2271
|
|
jpayne@68
|
2272 - New command line options in xz: --single-stream,
|
|
jpayne@68
|
2273 --block-size=SIZE, --block-list=SIZES,
|
|
jpayne@68
|
2274 --flush-timeout=TIMEOUT, and --ignore-check.
|
|
jpayne@68
|
2275
|
|
jpayne@68
|
2276 - xz -lvv now shows the minimum xz version that is required to
|
|
jpayne@68
|
2277 decompress the file. Currently it is 5.0.0 for all supported
|
|
jpayne@68
|
2278 .xz files except files with empty LZMA2 streams require 5.0.2.
|
|
jpayne@68
|
2279
|
|
jpayne@68
|
2280 * xzdiff and xzgrep now support .lzo files if lzop is installed.
|
|
jpayne@68
|
2281 The .tzo suffix is also recognized as a shorthand for .tar.lzo.
|
|
jpayne@68
|
2282
|
|
jpayne@68
|
2283
|
|
jpayne@68
|
2284 5.1.4beta (2014-09-14)
|
|
jpayne@68
|
2285
|
|
jpayne@68
|
2286 * All fixes from 5.0.6
|
|
jpayne@68
|
2287
|
|
jpayne@68
|
2288 * liblzma: Fixed the use of presets in threaded encoder
|
|
jpayne@68
|
2289 initialization.
|
|
jpayne@68
|
2290
|
|
jpayne@68
|
2291 * xz --block-list and --block-size can now be used together
|
|
jpayne@68
|
2292 in single-threaded mode. Previously the combination only
|
|
jpayne@68
|
2293 worked in multi-threaded mode.
|
|
jpayne@68
|
2294
|
|
jpayne@68
|
2295 * Added support for LZMA_IGNORE_CHECK to liblzma and made it
|
|
jpayne@68
|
2296 available in xz as --ignore-check.
|
|
jpayne@68
|
2297
|
|
jpayne@68
|
2298 * liblzma speed optimizations:
|
|
jpayne@68
|
2299
|
|
jpayne@68
|
2300 - Initialization of a new LZMA1 or LZMA2 encoder has been
|
|
jpayne@68
|
2301 optimized. (The speed of reinitializing an already-allocated
|
|
jpayne@68
|
2302 encoder isn't affected.) This helps when compressing many
|
|
jpayne@68
|
2303 small buffers with lzma_stream_buffer_encode() and other
|
|
jpayne@68
|
2304 similar situations where an already-allocated encoder state
|
|
jpayne@68
|
2305 isn't reused. This speed-up is visible in xz too if one
|
|
jpayne@68
|
2306 compresses many small files one at a time instead running xz
|
|
jpayne@68
|
2307 once and giving all files as command-line arguments.
|
|
jpayne@68
|
2308

jpayne@68
|
2309 - Buffer comparisons are now much faster when unaligned access
|
|
jpayne@68
|
2310 is allowed (configured with --enable-unaligned-access). This
|
|
jpayne@68
|
2311 speeds up encoding significantly. There is arch-specific code
|
|
jpayne@68
|
2312 for 32-bit and 64-bit x86 (32-bit needs SSE2 for the best
|
|
jpayne@68
|
2313 results and there's no run-time CPU detection for now).
|
|
jpayne@68
|
2314 For other archs there is only generic code which probably
|
|
jpayne@68
|
2315 isn't as optimal as arch-specific solutions could be.
|
|
jpayne@68
|
2316
|
|
jpayne@68
|
2317 - A few speed optimizations were made to the SHA-256 code.
|
|
jpayne@68
|
2318 (Note that the builtin SHA-256 code isn't used on all
|
|
jpayne@68
|
2319 operating systems.)
|
|
jpayne@68
|
2320
|
|
jpayne@68
|
2321 * liblzma can now be built with MSVC 2013 update 2 or later
|
|
jpayne@68
|
2322 using windows/config.h.
|
|
jpayne@68
|
2323
|
|
jpayne@68
|
2324 * Vietnamese translation was added.

2327 5.1.3alpha (2013-10-26)
|
|
jpayne@68
|
2328
|
|
jpayne@68
|
2329 * All fixes from 5.0.5
|
|
jpayne@68
|
2330
|
|
jpayne@68
|
2331 * liblzma:
|
|
jpayne@68
|
2332
|
|
jpayne@68
|
2333 - Fixed a deadlock in the threaded encoder.
|
|
jpayne@68
|
2334
|
|
jpayne@68
|
2335 - Made the uses of lzma_allocator const correct.
|
|
jpayne@68
|
2336
|
|
jpayne@68
|
2337 - Added lzma_block_uncomp_encode() to create uncompressed
|
|
jpayne@68
|
2338 .xz Blocks using LZMA2 uncompressed chunks.
|
|
jpayne@68
|
2339
|
|
jpayne@68
|
2340 - Added support for native threads on Windows and the ability
|
|
jpayne@68
|
2341 to detect the number of CPU cores.
|
|
jpayne@68
|
2342
|
|
jpayne@68
|
2343 * xz:
|
|
jpayne@68
|
2344
|
|
jpayne@68
|
2345 - Fixed a race condition in the signal handling. It was
|
|
jpayne@68
|
2346 possible that e.g. the first SIGINT didn't make xz exit
|
|
jpayne@68
|
2347 if reading or writing blocked and one had bad luck. The fix
|
|
jpayne@68
|
2348 is non-trivial, so as of writing it is unknown if it will be
|
|
jpayne@68
|
2349 backported to the v5.0 branch.
|
|
jpayne@68
|
2350
|
|
jpayne@68
|
2351 - Made the progress indicator work correctly in threaded mode.
|
|
jpayne@68
|
2352
|
|
jpayne@68
|
2353 - Threaded encoder now works together with --block-list=SIZES.
|
|
jpayne@68
|
2354
|
|
jpayne@68
|
2355 - Added preliminary support for --flush-timeout=TIMEOUT.
|
|
jpayne@68
|
2356 It can be useful for (somewhat) real-time streaming. For
|
|
jpayne@68
|
2357 now the decompression side has to be done with something
|
|
jpayne@68
|
2358 else than the xz tool due to how xz does buffering, but this
|
|
jpayne@68
|
2359 should be fixed.
|
|
jpayne@68
|
2360
|
|
jpayne@68
|
2361
|
|
jpayne@68
|
2362 5.1.2alpha (2012-07-04)
|
|
jpayne@68
|
2363
|
|
jpayne@68
|
2364 * All fixes from 5.0.3 and 5.0.4
|
|
jpayne@68
|
2365
|
|
jpayne@68
|
2366 * liblzma:
|
|
jpayne@68
|
2367
|
|
jpayne@68
|
2368 - Fixed a deadlock and an invalid free() in the threaded encoder.
|
|
jpayne@68
|
2369
|
|
jpayne@68
|
2370 - Added support for symbol versioning. It is enabled by default
|
|
jpayne@68
|
2371 on GNU/Linux, other GNU-based systems, and FreeBSD.
|
|
jpayne@68
|
2372
|
|
jpayne@68
|
2373 - Use SHA-256 implementation from the operating system if one is
|
|
jpayne@68
|
2374 available in libc, libmd, or libutil. liblzma won't use e.g.
|
|
jpayne@68
|
2375 OpenSSL or libgcrypt to avoid introducing new dependencies.
|
|
jpayne@68
|
2376
|
|
jpayne@68
|
2377 - Fixed liblzma.pc for static linking.
|
|
jpayne@68
|
2378
|
|
jpayne@68
|
2379 - Fixed a few portability bugs.
|
|
jpayne@68
|
2380
|
|
jpayne@68
|
2381 * xz --decompress --single-stream now fixes the input position after
|
|
jpayne@68
|
2382 successful decompression. Now the following works:
|
|
jpayne@68
|
2383
|
|
jpayne@68
|
2384 echo foo | xz > foo.xz
|
|
jpayne@68
|
2385 echo bar | xz >> foo.xz
|
|
jpayne@68
|
2386 ( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz
|
|
jpayne@68
|
2387
|
|
jpayne@68
|
2388 Note that it doesn't work if the input is not seekable
|
|
jpayne@68
|
2389 or if there is Stream Padding between the concatenated
|
|
jpayne@68
|
2390 .xz Streams.
|
|
jpayne@68
|
2391
|
|
jpayne@68
|
2392 * xz -lvv now shows the minimum xz version that is required to
|
|
jpayne@68
|
2393 decompress the file. Currently it is 5.0.0 for all supported .xz
|
|
jpayne@68
|
2394 files except files with empty LZMA2 streams require 5.0.2.
|
|
jpayne@68
|
2395
|
|
jpayne@68
|
2396 * Added an *incomplete* implementation of --block-list=SIZES to xz.
|
|
jpayne@68
|
2397 It only works correctly in single-threaded mode and when
|
|
jpayne@68
|
2398 --block-size isn't used at the same time. --block-list allows
|
|
jpayne@68
|
2399 specifying the sizes of Blocks which can be useful e.g. when
|
|
jpayne@68
|
2400 creating files for random-access reading.
|
|
jpayne@68
|
2401
|
|
jpayne@68
|
2402
|
|
jpayne@68
|
2403 5.1.1alpha (2011-04-12)
|
|
jpayne@68
|
2404
|
|
jpayne@68
|
2405 * All fixes from 5.0.2
|
|
jpayne@68
|
2406
|
|
jpayne@68
|
2407 * liblzma fixes that will also be included in 5.0.3:
|
|
jpayne@68
|
2408
|
|
jpayne@68
|
2409 - A memory leak was fixed.
|
|
jpayne@68
|
2410
|
|
jpayne@68
|
2411 - lzma_stream_buffer_encode() no longer creates an empty .xz
|
|
jpayne@68
|
2412 Block if encoding an empty buffer. Such an empty Block with
|
|
jpayne@68
|
2413 LZMA2 data would trigger a bug in 5.0.1 and older (see the
|
|
jpayne@68
|
2414 first bullet point in 5.0.2 notes). When releasing 5.0.2,
|
|
jpayne@68
|
2415 I thought that no encoder creates this kind of files but
|
|
jpayne@68
|
2416 I was wrong.
|
|
jpayne@68
|
2417
|
|
jpayne@68
|
2418 - Validate function arguments better in a few functions. Most
|
|
jpayne@68
|
2419 importantly, specifying an unsupported integrity check to
|
|
jpayne@68
|
2420 lzma_stream_buffer_encode() no longer creates a corrupt .xz
|
|
jpayne@68
|
2421 file. Probably no application tries to do that, so this
|
|
jpayne@68
|
2422 shouldn't be a big problem in practice.
|
|
jpayne@68
|
2423
|
|
jpayne@68
|
2424 - Document that lzma_block_buffer_encode(),
|
|
jpayne@68
|
2425 lzma_easy_buffer_encode(), lzma_stream_encoder(), and
|
|
jpayne@68
|
2426 lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
|
|
jpayne@68
|
2427
|
|
jpayne@68
|
2428 - The return values of the _memusage() functions are now
|
|
jpayne@68
|
2429 documented better.
|
|
jpayne@68
|
2430
|
|
jpayne@68
|
2431 * Support for multithreaded compression was added using the simplest
|
|
jpayne@68
|
2432 method, which splits the input data into blocks and compresses
|
|
jpayne@68
|
2433 them independently. Other methods will be added in the future.
|
|
jpayne@68
|
2434 The current method has room for improvement, e.g. it is possible
|
|
jpayne@68
|
2435 to reduce the memory usage.
|
|
jpayne@68
|
2436
|
|
jpayne@68
|
2437 * Added the options --single-stream and --block-size=SIZE to xz.
|
|
jpayne@68
|
2438
|
|
jpayne@68
|
2439 * xzdiff and xzgrep now support .lzo files if lzop is installed.
|
|
jpayne@68
|
2440 The .tzo suffix is also recognized as a shorthand for .tar.lzo.
|
|
jpayne@68
|
2441
|
|
jpayne@68
|
2442 * Support for short 8.3 filenames under DOS was added to xz. It is
|
|
jpayne@68
|
2443 experimental and may change before it gets into a stable release.
|
|
jpayne@68
|
2444
|
|
jpayne@68
|
2445
|
|
jpayne@68
|
2446 5.0.8 (2014-12-21)
|
|
jpayne@68
|
2447
|
|
jpayne@68
|
2448 * Fixed an old bug in xzgrep that affected OpenBSD and probably
|
|
jpayne@68
|
2449 a few other operating systems too.
|
|
jpayne@68
|
2450
|
|
jpayne@68
|
2451 * Updated French and German translations.
|
|
jpayne@68
|
2452
|
|
jpayne@68
|
2453 * Added support for detecting the amount of RAM on AmigaOS/AROS.
|
|
jpayne@68
|
2454
|
|
jpayne@68
|
2455 * Minor build system updates.
|
|
jpayne@68
|
2456

|
jpayne@68
|
2457
|
|
jpayne@68
|
2458 5.0.7 (2014-09-20)
|
|
jpayne@68
|
2459
|
|
jpayne@68
|
2460 * Fix regressions introduced in 5.0.6:
|
|
jpayne@68
|
2461
|
|
jpayne@68
|
2462 - Fix building with non-GNU make.
|
|
jpayne@68
|
2463
|
|
jpayne@68
|
2464 - Fix invalid Libs.private value in liblzma.pc which broke
|
|
jpayne@68
|
2465 static linking against liblzma if the linker flags were
|
|
jpayne@68
|
2466 taken from pkg-config.
|
|
jpayne@68
|
2467
|
|
jpayne@68
|
2468
|
|
jpayne@68
|
2469 5.0.6 (2014-09-14)
|
|
jpayne@68
|
2470
|
|
jpayne@68
|
2471 * xzgrep now exits with status 0 if at least one file matched.
|
|
jpayne@68
|
2472
|
|
jpayne@68
|
2473 * A few minor portability and build system fixes
|
|
jpayne@68
|
2474
|
|
jpayne@68
|
2475
|
|
jpayne@68
|
2476 5.0.5 (2013-06-30)
|
|
jpayne@68
|
2477
|
|
jpayne@68
|
2478 * lzmadec and liblzma's lzma_alone_decoder(): Support decompressing
|
|
jpayne@68
|
2479 .lzma files that have less common settings in the headers
|
|
jpayne@68
|
2480 (dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed
|
|
jpayne@68
|
2481 size greater than 256 GiB). The limitations existed to avoid false
|
|
jpayne@68
|
2482 positives when detecting .lzma files. The lc + lp <= 4 limitation
|
|
jpayne@68
|
2483 still remains since liblzma's LZMA decoder has that limitation.
|
|
jpayne@68
|
2484
|
|
jpayne@68
|
2485 NOTE: xz's .lzma support or liblzma's lzma_auto_decoder() are NOT
|
|
jpayne@68
|
2486 affected by this change. They still consider uncommon .lzma headers
|
|
jpayne@68
|
2487 as not being in the .lzma format. Changing this would give way too
|
|
jpayne@68
|
2488 many false positives.
|
|
jpayne@68
|
2489
|
|
jpayne@68
|
2490 * xz:
|
|
jpayne@68
|
2491
|
|
jpayne@68
|
2492 - Interaction of preset and custom filter chain options was
|
|
jpayne@68
|
2493 made less illogical. This affects only certain less typical
|
|
jpayne@68
|
2494 uses cases so few people are expected to notice this change.
|
|
jpayne@68
|
2495
|
|
jpayne@68
|
2496 Now when a custom filter chain option (e.g. --lzma2) is
|
|
jpayne@68
|
2497 specified, all preset options (-0 ... -9, -e) earlier are on
|
|
jpayne@68
|
2498 the command line are completely forgotten. Similarly, when
|
|
jpayne@68
|
2499 a preset option is specified, all custom filter chain options
|
|
jpayne@68
|
2500 earlier on the command line are completely forgotten.
|
|
jpayne@68
|
2501
|
|
jpayne@68
|
2502 Example 1: "xz -9 --lzma2=preset=5 -e" is equivalent to "xz -e"
|
|
jpayne@68
|
2503 which is equivalent to "xz -6e". Earlier -e didn't put xz back
|
|
jpayne@68
|
2504 into preset mode and thus the example command was equivalent
|
|
jpayne@68
|
2505 to "xz --lzma2=preset=5".
|
|
jpayne@68
|
2506
|
|
jpayne@68
|
2507 Example 2: "xz -9e --lzma2=preset=5 -7" is equivalent to
|
|
jpayne@68
|
2508 "xz -7". Earlier a custom filter chain option didn't make
|
|
jpayne@68
|
2509 xz forget the -e option so the example was equivalent to
|
|
jpayne@68
|
2510 "xz -7e".
|
|
jpayne@68
|
2511
|
|
jpayne@68
|
2512 - Fixes and improvements to error handling.
|
|
jpayne@68
|
2513
|
|
jpayne@68
|
2514 - Various fixes to the man page.
|
|
jpayne@68
|
2515
|
|
jpayne@68
|
2516 * xzless: Fixed to work with "less" versions 448 and later.
|
|
jpayne@68
|
2517
|
|
jpayne@68
|
2518 * xzgrep: Made -h an alias for --no-filename.
|
|
jpayne@68
|
2519
|
|
jpayne@68
|
2520 * Include the previously missing debug/translation.bash which can
|
|
jpayne@68
|
2521 be useful for translators.
|
|
jpayne@68
|
2522
|
|
jpayne@68
|
2523 * Include a build script for Mac OS X. This has been in the Git
|
|
jpayne@68
|
2524 repository since 2010 but due to a mistake in Makefile.am the
|
|
jpayne@68
|
2525 script hasn't been included in a release tarball before.
|
|
jpayne@68
|
2526
|
|
jpayne@68
|
2527
|
|
jpayne@68
|
2528 5.0.4 (2012-06-22)
|
|
jpayne@68
|
2529
|
|
jpayne@68
|
2530 * liblzma:
|
|
jpayne@68
|
2531
|
|
jpayne@68
|
2532 - Fix lzma_index_init(). It could crash if memory allocation
|
|
jpayne@68
|
2533 failed.
|
|
jpayne@68
|
2534
|
|
jpayne@68
|
2535 - Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ
|
|
jpayne@68
|
2536 filter is used and the application only provides exactly as
|
|
jpayne@68
|
2537 much output space as is the uncompressed size of the file.
|
|
jpayne@68
|
2538
|
|
jpayne@68
|
2539 - Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't
|
|
jpayne@68
|
2540 check if the last call to lzma_code() really returned
|
|
jpayne@68
|
2541 LZMA_STREAM_END, which made the program think that truncated
|
|
jpayne@68
|
2542 files are valid.
|
|
jpayne@68
|
2543
|
|
jpayne@68
|
2544 - New example programs in doc/examples (old programs are now in
|
|
jpayne@68
|
2545 doc/examples_old). These have more comments and more detailed
|
|
jpayne@68
|
2546 error handling.
|
|
jpayne@68
|
2547
|
|
jpayne@68
|
2548 * Fix "xz -lvv foo.xz". It could crash on some corrupted files.
|
|
jpayne@68
|
2549
|
|
jpayne@68
|
2550 * Fix output of "xz --robot -lv" and "xz --robot -lvv" which
|
|
jpayne@68
|
2551 incorrectly printed the filename also in the "foo (x/x)" format.
|
|
jpayne@68
|
2552
|
|
jpayne@68
|
2553 * Fix exit status of "xzdiff foo.xz bar.xz".
|
|
jpayne@68
|
2554
|
|
jpayne@68
|
2555 * Fix exit status of "xzgrep foo binary_file".
|
|
jpayne@68
|
2556
|
|
jpayne@68
|
2557 * Fix portability to EBCDIC systems.
|
|
jpayne@68
|
2558
|
|
jpayne@68
|
2559 * Fix a configure issue on AIX with the XL C compiler. See INSTALL

2560 for details.
|
|
jpayne@68
|
2561
|
|
jpayne@68
|
2562 * Update French, German, Italian, and Polish translations.

2565 5.0.3 (2011-05-21)
|
|
jpayne@68
|
2566
|
|
jpayne@68
|
2567 * liblzma fixes:
|
|
jpayne@68
|
2568
|
|
jpayne@68
|
2569 - A memory leak was fixed.
|
|
jpayne@68
|
2570
|
|
jpayne@68
|
2571 - lzma_stream_buffer_encode() no longer creates an empty .xz
|
|
jpayne@68
|
2572 Block if encoding an empty buffer. Such an empty Block with
|
|
jpayne@68
|
2573 LZMA2 data would trigger a bug in 5.0.1 and older (see the
|
|
jpayne@68
|
2574 first bullet point in 5.0.2 notes). When releasing 5.0.2,
|
|
jpayne@68
|
2575 I thought that no encoder creates this kind of files but
|
|
jpayne@68
|
2576 I was wrong.
|
|
jpayne@68
|
2577
|
|
jpayne@68
|
2578 - Validate function arguments better in a few functions. Most
|
|
jpayne@68
|
2579 importantly, specifying an unsupported integrity check to
|
|
jpayne@68
|
2580 lzma_stream_buffer_encode() no longer creates a corrupt .xz
|
|
jpayne@68
|
2581 file. Probably no application tries to do that, so this
|
|
jpayne@68
|
2582 shouldn't be a big problem in practice.
|
|
jpayne@68
|
2583
|
|
jpayne@68
|
2584 - Document that lzma_block_buffer_encode(),
|
|
jpayne@68
|
2585 lzma_easy_buffer_encode(), lzma_stream_encoder(), and
|
|
jpayne@68
|
2586 lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
|
|
jpayne@68
|
2587
|
|
jpayne@68
|
2588 - The return values of the _memusage() functions are now
|
|
jpayne@68
|
2589 documented better.
|
|
jpayne@68
|
2590
|
|
jpayne@68
|
2591 * Fix command name detection in xzgrep. xzegrep and xzfgrep now
|
|
jpayne@68
|
2592 correctly use egrep and fgrep instead of grep.
|
|
jpayne@68
|
2593
|
|
jpayne@68
|
2594 * French translation was added.
|
|
jpayne@68
|
2595
|
|
jpayne@68
|
2596
|
|
jpayne@68
|
2597 5.0.2 (2011-04-01)
|
|
jpayne@68
|
2598
|
|
jpayne@68
|
2599 * LZMA2 decompressor now correctly accepts LZMA2 streams with no
|
|
jpayne@68
|
2600 uncompressed data. Previously it considered them corrupt. The
|
|
jpayne@68
|
2601 bug can affect applications that use raw LZMA2 streams. It is
|
|
jpayne@68
|
2602 very unlikely to affect .xz files because no compressor creates
|
|
jpayne@68
|
2603 .xz files with empty LZMA2 streams. (Empty .xz files are a
|
|
jpayne@68
|
2604 different thing than empty LZMA2 streams.)
|
|
jpayne@68
|
2605
|
|
jpayne@68
|
2606 * "xz --suffix=.foo filename.foo" now refuses to compress the
|
|
jpayne@68
|
2607 file due to it already having the suffix .foo. It was already
|
|
jpayne@68
|
2608 documented on the man page, but the code lacked the test.
|
|
jpayne@68
|
2609
|
|
jpayne@68
|
2610 * "xzgrep -l foo bar.xz" works now.
|
|
jpayne@68
|
2611
|
|
jpayne@68
|
2612 * Polish translation was added.
|
|
jpayne@68
|
2613
|
|
jpayne@68
|
2614
|
|
jpayne@68
|
2615 5.0.1 (2011-01-29)
|
|
jpayne@68
|
2616
|
|
jpayne@68
|
2617 * xz --force now (de)compresses files that have setuid, setgid,
|
|
jpayne@68
|
2618 or sticky bit set and files that have multiple hard links.
|
|
jpayne@68
|
2619 The man page had it documented this way already, but the code
|
|
jpayne@68
|
2620 had a bug.
|
|
jpayne@68
|
2621
|
|
jpayne@68
|
2622 * gzip and bzip2 support in xzdiff was fixed.
|
|
jpayne@68
|
2623
|
|
jpayne@68
|
2624 * Portability fixes
|
|
jpayne@68
|
2625
|
|
jpayne@68
|
2626 * Minor fix to Czech translation
|
|
jpayne@68
|
2627
|
|
jpayne@68
|
2628
|
|
jpayne@68
|
2629 5.0.0 (2010-10-23)
|
|
jpayne@68
|
2630
|
|
jpayne@68
|
2631 Only the most important changes compared to 4.999.9beta are listed
|
|
jpayne@68
|
2632 here. One change is especially important:
|
|
jpayne@68
|
2633
|
|
jpayne@68
|
2634 * The memory usage limit is now disabled by default. Some scripts
|
|
jpayne@68
|
2635 written before this change may have used --memory=max on xz command
|
|
jpayne@68
|
2636 line or in XZ_OPT. THESE USES OF --memory=max SHOULD BE REMOVED
|
|
jpayne@68
|
2637 NOW, because they interfere with user's ability to set the memory
|
|
jpayne@68
|
2638 usage limit himself. If user-specified limit causes problems to
|
|
jpayne@68
|
2639 your script, blame the user.
|
|
jpayne@68
|
2640
|
|
jpayne@68
|
2641 Other significant changes:
|
|
jpayne@68
|
2642
|
|
jpayne@68
|
2643 * Added support for XZ_DEFAULTS environment variable. This variable
|
|
jpayne@68
|
2644 allows users to set default options for xz, e.g. default memory
|
|
jpayne@68
|
2645 usage limit or default compression level. Scripts that use xz
|
|
jpayne@68
|
2646 must never set or unset XZ_DEFAULTS. Scripts should use XZ_OPT
|
|
jpayne@68
|
2647 instead if they need a way to pass options to xz via an
|
|
jpayne@68
|
2648 environment variable.
|
|
jpayne@68
|
2649
|
|
jpayne@68
|
2650 * The compression settings associated with the preset levels
|
|
jpayne@68
|
2651 -0 ... -9 have been changed. --extreme was changed a little too.
|
|
jpayne@68
|
2652 It is now less likely to make compression worse, but with some
|
|
jpayne@68
|
2653 files the new --extreme may compress slightly worse than the old
|
|
jpayne@68
|
2654 --extreme.
|
|
jpayne@68
|
2655
|
|
jpayne@68
|
2656 * If a preset level (-0 ... -9) is specified after a custom filter
|
|
jpayne@68
|
2657 chain options have been used (e.g. --lzma2), the custom filter
|
|
jpayne@68
|
2658 chain will be forgotten. Earlier the preset options were
|
|
jpayne@68
|
2659 completely ignored after custom filter chain options had been
|
|
jpayne@68
|
2660 seen.
|
|
jpayne@68
|
2661
|
|
jpayne@68
|
2662 * xz will create sparse files when decompressing if the uncompressed
|
|
jpayne@68
|
2663 data contains long sequences of binary zeros. This is done even
|
|
jpayne@68
|
2664 when writing to standard output that is connected to a regular
|
|
jpayne@68
|
2665 file and certain additional conditions are met to make it safe.
|
|
jpayne@68
|
2666
|
|
jpayne@68
|
2667 * Support for "xz --list" was added. Combine with --verbose or
|
|
jpayne@68
|
2668 --verbose --verbose (-vv) for detailed output.
|
|
jpayne@68
|
2669
|
|
jpayne@68
|
2670 * I had hoped that liblzma API would have been stable after
|
|
jpayne@68
|
2671 4.999.9beta, but there have been a couple of changes in the
|
|
jpayne@68
|
2672 advanced features, which don't affect most applications:
|
|
jpayne@68
|
2673
|
|
jpayne@68
|
2674 - Index handling code was revised. If you were using the old
|
|
jpayne@68
|
2675 API, you will get a compiler error (so it's easy to notice).
|
|
jpayne@68
|
2676
|
|
jpayne@68
|
2677 - A subtle but important change was made to the Block handling
|
|
jpayne@68
|
2678 API. lzma_block.version has to be initialized even for
|
|
jpayne@68
|
2679 lzma_block_header_decode(). Code that doesn't do it will work
|
|
jpayne@68
|
2680 for now, but might break in the future, which makes this API
|
|
jpayne@68
|
2681 change easy to miss.
|
|
jpayne@68
|
2682
|
|
jpayne@68
|
2683 * The major soname has been bumped to 5.0.0. liblzma API and ABI
|
|
jpayne@68
|
2684 are now stable, so the need to recompile programs linking against
|
|
jpayne@68
|
2685 liblzma shouldn't arise soon.
|
|
jpayne@68
|
2686
