Lasse Collin 465d1b0d65 Create sparse files by default when decompressing into
a regular file.

Sparse file creation can be disabled with --no-sparse.
I don't promise yet that the name of this option won't
change before 5.0.0. It's possible that the code, that
checks when it is safe to use sparse output on stdout,
is not good enough, and a more flexible command line
option is needed to configure sparse file handling.

Lasse Collin f1a28b96c9 Add missing consts to pointer casts. 2009-11-22 12:05:33 +02:00
Lasse Collin 0733f4c999 Make fastpos.h use tuklib_integer.h instead of bsr.h
when --enable-small has been specified.
2009-11-22 11:55:03 +02:00
Lasse Collin 7ac3985d89 Update tuklib_integer.h with bit scan functions.
Thanks to Joachim Henke for the original patch.
2009-11-22 11:52:30 +02:00
Lasse Collin d315ca4930 Add support for --info-memory and --robot to xz.
Currently --robot works only with --info-memory and
--version. --help and --long-help work too, but --robot
has no effect on them.

Thanks to Jonathan Nieder for the original patches.

Lasse Collin e330fb7e6b Fix wrong indentation caused by incorrect settings
in the text editor.
2009-11-15 12:54:45 +02:00
Lasse Collin 93e418562c Add lzma_physmem().
I had hoped to keep liblzma as purely a compression
library as possible (e.g. file I/O will go into
a different library), but it seems that applications
linking agaisnt liblzma need some way to determine
the memory usage limit, and knowing the amount of RAM
is one reasonable way to help making such decisions.

Thanks to Jonathan Nieder for the original patch.

Lasse Collin 2ddcae247c Some updates to xz man page. 2009-11-14 20:20:03 +02:00
Lasse Collin 19b2674f07 Fix description of --memory in --long-help. 2009-11-14 19:51:03 +02:00
Lasse Collin 418d64a32e Fix a design error in liblzma API.
Originally the idea was that using LZMA_FULL_FLUSH
with Stream encoder would read the filter chain
from the same array that was used to intialize the
Stream encoder. Since most apps wouldn't use
LZMA_FULL_FLUSH, most apps wouldn't need to keep
the filter chain available after initializing the
Stream encoder. However, due to my mistake, it
actually required keeping the array always available.

Since setting the new filter chain via the array
used at initialization time is not a nice way to do
it for a couple of reasons, this commit ditches it
and introduces lzma_filters_update(). This new function
replaces also the "persistent" flag used by LZMA2
(and to-be-designed Subblock filter), which was also
an ugly thing to do.

Thanks to Alexey Tourbin for reminding me about the problem
that Stream encoder used to require keeping the filter
chain allocated.
2009-11-14 18:59:19 +02:00
Lasse Collin f0bf7634b7 Fix wrong function name in the previous commit.
It was meant to be lzma_filters_copy(), not lzma_filters_dup().
2009-10-17 11:11:58 +03:00
Lasse Collin 6d118a0b9d Add lzma_filters_copy().
This will be needed internally by liblzma once I fix
a design mistake in the encoder API. This function may
be useful to applications too so it's good to export it.
2009-10-17 01:47:07 +03:00
Jonathan Nieder 78e92c1847 Escape dashes in xzmore.1
A minus sign is larger, easier to see in a printout, and more
likely to use the same glyph as ASCII hyphen-minus in a terminal
than a hyphen.  Since broken manual pagers do not find hyphens
when the user searches for a hyphen-minus, minus signs are also
easier to search for.  So use minus signs instead of hyphens to
render sample terminal output.
2009-10-16 20:39:24 +03:00
Lasse Collin 7b7fe902d9 Mention --check=none in --long-help. It was already in
the man page though.

Thanks to Jim Meyering for noticing this.
2009-10-16 20:35:39 +03:00
Lasse Collin ebfb2c5e1f Use a tuklib module for integer handling.
This replaces bswap.h and integer.h.

The tuklib module uses <byteswap.h> on GNU,
<sys/endian.h> on *BSDs and <sys/byteorder.h>
on Solaris, which may contain optimized code
like inline assembly.
2009-10-04 22:57:12 +03:00
Lasse Collin 29fd321033 Add support for --enable-assume-ram=SIZE. 2009-10-02 14:35:56 +03:00
Lasse Collin 3782b3fee4 Use unaligned access (if possible) on both endiannesses
in lz_encoder_hash.h.
2009-10-02 11:28:17 +03:00
Lasse Collin c5f68b5cc7 Make liblzma produce the same output on both endiannesses.
Seems that it is a problem in some cases if the same
version of XZ Utils produces different output on different
endiannesses, so this commit fixes that problem. The output
will still vary between different XZ Utils versions, but I
cannot avoid that for now.

This commit bloatens the code on big endian systems by 1 KiB,
which should be OK since liblzma is bloated already. ;-)

Lasse Collin 0deb1bb60a Make sure that TUKLIB_DOSLIKE doesn't get defined on Cygwin.
Thanks to Charles Wilson.
2009-09-21 19:50:09 +03:00
Lasse Collin e599bba421 Various changes.
Separate a few reusable components from XZ Utils specific
code. The reusable code is now in "tuklib" modules. A few
more could be separated still, e.g. bswap.h.

Fix some bugs in lzmainfo.

Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol
for help.

Add OpenVMS support into physmem. Add a few #ifdefs to ease
building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the
original patch.

Lasse Collin 221be761f4 Use $(LN_EXEEXT) in symlinks to executables.
This fixes "make install" on operating systems using
a suffix for executables.

Cygwin is treated specially. The symlink names won't have
.exe suffix even though the executables themselves have.
Thanks to Charles Wilson.

Lasse Collin 18a4233a53 Fix a couple of warnings. 2009-09-11 09:25:09 +03:00
Lasse Collin 429910b2ba Add OS/2-specific code to physmem.h.
Also move DJGPP-specific code near the code meant
for other DOS-like systems.
2009-09-05 18:39:21 +03:00
Lasse Collin 60ccb80c9c Use sysctl() != -1 instead of !sysctl() to check if
the function call succeeded.

NetBSD 4.0 returns positive values on success, but
NetBSD Current and FreeBSD return zero. OpenBSD's
man page doesn't tell what sysctl() returns on
success. All these BSDs return -1 on error.

Thanks to Robert Elz and Thomas Klausner.

Lasse Collin 319a0fd7d7 Refactored option parsing. 2009-09-01 20:40:01 +03:00
Lasse Collin 25adaaa56e Fix options parsing bug in xz.
xz used to reject "xz --lzma2=pb=2," while
"xz --lzma2=pb=2,," worked. Now both work.
2009-09-01 20:23:30 +03:00
Lasse Collin 655457b9ad Revert 43f44160b1
and use a fix that works on all systems using
GNU assembler.

Maybe the assembler code is used e.g. on Solaris x86
but let's worry about it if this doesn't work on it.
2009-08-31 21:59:25 +03:00
Lasse Collin 94c66b3297 Use even more hackish way to support thousand separators.
Seems that in addition on Windows and DOS, also OpenBSD
lacks support for %'d style printf() format strings.
So far that is the only modern POSIX-like system I know
with this problem, but after this hack, the thousand
separator shouldn't be a problem on any system.

Maybe testing if a format string like %'d produces
reasonable output is invoking undefined behavior on some
systems, but so far all the problematic systems I've tried
just print the raw format string (e.g. %'d prints 'd).

Maybe Autoconf test would have been better, but this
hack works also for cross-compilation, and avoids
recompilation in case the system libc starts to support
the thousand separator.
2009-08-29 14:43:52 +03:00
Lasse Collin 27414daadf Fix sysctl() usage.
This fixes build on *BSDs and Darwin.

Lasse Collin 3e2ba8b585 Updates to liblzma API headers.
Added lzma_nothrow for every function. It adds
throw() when the header is used in C++ code.

Some lzma_attrs were added or removed.

Lots of comments were improved.

Lasse Collin 5aa4678b23 Fix xz Makefile.am for the man page.
install-exec-hook -> install-data-hook
2009-08-13 12:56:47 +03:00
Lasse Collin e51b4e49e8 Add lzmainfo for backward compatibility with LZMA Utils.
lzmainfo now links against static liblzma. In contrast
to other command line tools in XZ Utils, linking lzmainfo
against static liblzma by default is dumb. This will be
fixed once I have fixed some related issues in configure.ac.
2009-08-13 12:55:45 +03:00
Lasse Collin a4165d0584 Sync some error messages from xz to xzdec.
Make xz error message translation usable outside
xz (at least in upcoming lzmainfo).

Lasse Collin 180bdf58ea Fix first line of xz man page. 2009-08-13 09:37:01 +03:00
Lasse Collin e1ce2291e7 Added a rough version of the xz man page. 2009-08-10 11:22:31 +03:00
Jonathan Nieder e71903fc61 “xzdiff a.xz b.xz” always fails
Attempts to compare two compressed files result in no output and
exit status 2.

Instead of going to standard output, ‘diff’ output is being
captured in the xz_status variable along with the exit status from
the decompression commands.  Later, when this variable is examined
for nonzero status codes, numerals from dates in the ‘diff’ output
make it appear as though decompression failed.

So let the ‘diff’ output leak to standard output with another file
descriptor.  (This trick is used in all similar contexts elsewhere
in xzdiff and in the analogous context in gzip’s zdiff script.)
2009-08-09 22:55:19 +03:00
Jonathan Nieder 1d314b81aa xzless: Support compressed standard input
It can be somewhat confusing that

	less < some_file.txt

works fine, whereas

	xzless < some_file.txt.xz

does not.  Since version 429, ‘less’ allows a filter specified in
the LESSOPEN environment variable to preprocess its input even if
it comes from standard input, if $LESSOPEN begins with ‘|-’.  So
set $LESSOPEN to take advantage of this feature.

Check less’s version at runtime so xzless can continue to work
with older versions.

Jonathan Nieder dbbd8fb870 xzdiff: add missing ;; to case statement 2009-07-30 12:23:45 +03:00

2009-07-23 19:10:55 +03:00
Lasse Collin 8f8ec942d6 Avoid internal error with --format=xz --lzma1. 2009-07-20 15:43:32 +03:00
Lasse Collin ef4cf1851d Added missing author notice to xzless.in. 2009-07-19 11:09:31 +03:00
Lasse Collin 64e498c89d Added public domain notice into a few files. 2009-07-18 11:26:39 +03:00
Lasse Collin a35755c5de Allow extra commas in filter-specific options on xz command line.
This may slightly ease writing scripts that construct
filter-specific option strings dynamically.
2009-07-14 21:10:36 +03:00
Lasse Collin 98f3cac1ad Accept --lzma2=preset=6e where "e" is equivalent to --extreme
when no custom chain is in use.
2009-07-14 18:04:31 +03:00
Lasse Collin cd69a5a6c1 BCJ filters: Reject invalid start offsets with LZMA_OPTIONS_ERROR.
This is a quick and slightly dirty fix to make the code
conform to the latest file format specification. Without
this patch, it's possible to make corrupt files by
specifying start offset that is not a multiple of the
filter's alignment. Custom start offset is almost never
used, so this was only a minor bug.

The xz command line tool doesn't validate the start offset,
so one will get a bit unclear error message if trying to use
an invalid start offset.
2009-07-10 11:39:38 +03:00
Lasse Collin eed9953732 Look for full command names instead of substrings
like "un", "cat", and "lz" when determining if
xz is run as unxz, xzcat, lzma, unlzma, or lzcat.

This is to ensure that if xz is renamed (e.g. via
--program-transform-name), it doesn't so easily
work in wrong mode.
2009-07-10 11:33:21 +03:00
Lasse Collin 3bdb53792c Remove --force from xzdec.
It was ignored for compatibility with xz, but now that
--decompress --stdout --force copies unrecognized files
as is to stdout, simply ignoring --force in xzdec would
be wrong. xzdec will not support copying unrecognized
data as is to stdout, so it cannot support --force.
2009-07-08 22:50:16 +03:00
Lasse Collin 5f16ef4abf Use sed instead of $(SED) so that we don't need to
use AC_PROG_SED. We don't do anything fancy with sed,
so this should work OK. libtool 2.2 sets SED but 1.5
doesn't, so $(SED) happened to work when using libtool 2.2.
2009-07-06 10:36:04 +03:00
Lasse Collin 96e4b257e1 Major update to the xzgrep and other scripts based on
the latest versions found from gzip CVS repository.

configure will try to find a POSIX shell to be used by
the scripts. This should ease portability on systems
which have pre-POSIX /bin/sh.

xzgrep and xzdiff support .xz, .lzma, .gz, and .bz2 files.
xzmore and xzless support only .xz and .lzma files.

The name of the xz executable used in these scripts is
now correct even if --program-transform-name has been used.
2009-07-05 22:25:17 +03:00
Lasse Collin 25cc7a6e8c Use @PACKAGE_HOMEPAGE@ in liblzma.pc.in. 2009-07-05 19:26:53 +03:00
Lasse Collin 18c10c30d2 Make "xz --decompress --stdout --force" copy unrecognized
files as is to standard output.

This feature is needed to be more compatible with gzip's
behavior. This was more complicated to implement than it
sounds, because the way liblzma is able to return errors with
files of only a few bytes in size. xz now has its own file
type detection code and no longer uses lzma_auto_decoder().
2009-07-04 00:40:44 +03:00
Lasse Collin 0a289c01ac Define PACKAGE_HOMEPAGE in configure.ac and use it in
xz and xzdec.

Use also PACKAGE_NAME instead of hardcoding "XZ Utils".
2009-07-02 14:30:38 +03:00
Lasse Collin f42ee98166 Build system fixes
Don't use libtool convenience libraries to avoid recently
discovered long-standing subtle but somewhat severe bugs
in libtool (at least 1.5.22 and 2.2.6 are affected). It
was found when porting XZ Utils to Windows
<http://lists.gnu.org/archive/html/libtool/2009-06/msg00070.html>
but the problem is significant also e.g. on GNU/Linux.

Unless --disable-shared is passed to configure, static
library built from a set of convenience libraries will
contain PIC objects. That is, while libtool builds non-PIC
objects too, only PIC objects will be used from the
convenience libraries. On 32-bit x86 (tested on mobile XP2400+),
using PIC instead of non-PIC makes the decompressor 10 % slower
with the default CFLAGS.

So while xz was linked against static liblzma by default,
it got the slower PIC objects unless --disable-shared was
used. I tend develop and benchmark with --disable-shared
due to faster build time, so I hadn't noticed the problem
in benchmarks earlier.

This commit also adds support for building Windows resources
into liblzma and executables.
2009-06-30 17:09:57 +03:00

Lasse Collin 4dd21d23f2 Remove the --info option, which was an alias for --list. 2009-05-22 14:21:20 +03:00
Lasse Collin 8836139b63 If xz is run as lzma, unlzma, or lzcat, simply imply
--format=lzma. This means that xz emulating lzma
doesn't decompress .xz files, while before this
commit it did. The new way is slightly simpler in
code and especially in upcoming documentation.
2009-05-22 12:27:43 +03:00
Lasse Collin b0063023f8 Make the default memory usage limit 40 % of RAM for both
compressing and decompressing. This should be OK now that
xz automatically scales down the compression settings if
they would exceed the memory usage limit (earlier, the limit
for compression was increased to 90 % because low limit broke
scripts that used "xz -9" on systems with low RAM).

Support spcifying the memory usage limit as a percentage
of RAM (e.g. --memory=50%).

Support --threads=0 to reset the thread limit to the default
value (number of available CPU cores). Use UINT32_MAX instead
of SIZE_MAX as the maximum in args.c. hardware.c was already
expecting uint32_t value.

Cleaned up the output of --help and --long-help.

Lasse Collin 071b825b23 Support special value "max" where xz and xzdec accept an integer.
Don't round the memory usage limit in xzdec --help to avoid
an integer overflow and to not give wrong impression that
the limit is high enough when it may not actually be.
2009-05-21 17:22:01 +03:00
ABCD 03ca67fd37 Install lzdiff, lzgrep, and lzmore as symlinks
This adds lzdiff, lzgrep, and lzmore to the list of symlinks to install.
It also installs symlinks for the manual pages and removes the new
symlinks on uninstall.
2009-05-21 16:25:36 +03:00
Lasse Collin a6f43e6412 Use a GCC-specific #pragma instead of GCC-specific
-Wno-uninitialized to silence a bogus warning.

Lasse Collin 21c6b94373 Fixed a crash in liblzma.
liblzma tries to avoid useless free()/malloc() pairs in
initialization when multiple files are handled using the
same lzma_stream. This didn't work with filter chains
due to comparison of wrong pointers in lzma_next_coder_init(),
making liblzma think that no memory reallocation is needed
even when it actually is.

Easy way to trigger this bug is to decompress two files with
a single xz command. The first file should have e.g. x86+LZMA2
as the filter chain, and the second file just LZMA2.
2009-04-28 23:08:32 +03:00
Lasse Collin e518d167aa Fix uint32_t -> size_t in ARM and ARM-Thumb filters.
On 64-bit system it would have gone into infinite
loop if a single input buffer was over 4 GiB (unlikely).
2009-04-15 14:13:38 +03:00
Lasse Collin 2f0bc9cd40 Quick & dirty update to support xz in diff/grep/more scripts. 2009-04-13 14:49:48 +03:00
Lasse Collin 02ddf09bc3 Put the interesting parts of XZ Utils into the public domain.
Some minor documentation cleanups were made at the same time.
2009-04-13 11:27:40 +03:00
Lasse Collin e79c42d854 Fix off-by-one in LZ decoder.
Fortunately, this bug had no security risk other than accepting
some corrupt files as valid.
2009-04-10 11:17:02 +03:00
Lasse Collin 390e69887f Fix wrong macro names in lc_cpucores.m4 and cpucores.h.
Thanks to Bert Wesarg.
2009-03-18 16:51:41 +02:00
Lasse Collin fd6a380f4e Add a rough explanation of --extreme to output of --help. 2009-02-22 19:07:54 +02:00
Lasse Collin 68bf7ac298 Fixes to progress message handling in xz:
- Don't use Windows-specific code on Windows. The old code
    required at least Windows 2000. Now it should work on
    Windows 98 and later, and maybe on Windows 95 too.

  - Use less precision when showing estimated remaining time.

  - Fix some small design issues.
2009-02-22 18:52:49 +02:00
Lasse Collin 47c2e21f82 Added files missing from the previous commit. 2009-02-18 13:00:10 +02:00
Lasse Collin 489a3dbaa0 Added lzma_easy_buffer_encode(). Splitted easy.c into small
pieces to avoid unneeded dependencies making statically
linked applications bigger than needed.
2009-02-17 10:43:00 +02:00
Lasse Collin 7494816ab0 Make physmem.h work on old Windows versions.
Thanks to Hongbo Ni for the original patch.
2009-02-15 15:48:45 +02:00
Lasse Collin 11ae4ae35f Fix microsecond vs. nanosecond confusion in my_time(). 2009-02-14 20:44:52 +02:00
Lasse Collin 3084d662d2 Cleanups to the code that detects the amount of RAM and
the number of CPU cores. Added support for using sysinfo()
on Linux systems whose libc lacks appropriate sysconf()
support (at least dietlibc). The Autoconf macros were
split into separate files, and CPU core count detection
was moved from hardware.c to cpucores.h. The core count
isn't used for anything real for now, so a problematic
part in process.c was commented out.
2009-02-14 00:45:29 +02:00
Lasse Collin fdbc0cfa71 Changed how the version number is specified in various places.
Now configure.ac will get the version number directly from
src/liblzma/api/lzma/version.h. The intent is to reduce the
number of places where the version number is duplicated. In
future, support for displaying Git commit ID may be added too.
2009-02-13 18:00:03 +02:00
Lasse Collin 1d924e584b Fix handling of integrity check type in the xz command line tool. 2009-02-13 17:30:30 +02:00
Lasse Collin 96c46df7de Improve support for DOS-like systems.
Here DOS-like means DOS, Windows, and OS/2.
2009-02-13 17:29:02 +02:00
Lasse Collin a3bbbe05d3 Let the user specify custom CFLAGS on the make command
line. Previously custom CFLAGS worked only when they were
passed to configure.
2009-02-09 14:54:31 +02:00
Lasse Collin 53f7598998 Fix aliasing issue in physmem.h. 2009-02-08 21:35:11 +02:00
Lasse Collin 0e27028d74 Add a separate internal function to initialize the CRC32
table, which is used also by LZ encoder. This was needed
because calling lzma_crc32() and ignoring the result is
a no-op due to lzma_attr_pure.
2009-02-08 18:24:50 +02:00
Lasse Collin ae1ad9af54 Make "xz --force" to write to terminal as the error
message suggests.
2009-02-08 18:17:05 +02:00
Lasse Collin 79e25eded4 Support both slash and backslash as path component
separator on Windows when parsing argv[0].
2009-02-08 10:37:50 +02:00
Lasse Collin 880c330938 Make it easy to choose if command line tools should be
linked statically or dynamically against liblzma. The
default is still to use static liblzma, but it can now
be changed by passing --enable-dynamic to configure.
Thanks to Mike Frysinger for the original patch.

Fixed a few minor bugs in configure.ac.
2009-02-07 21:17:07 +02:00
Lasse Collin bd7ca1dad5 Assume 32 MiB of RAM on unsupported operating systems like
the comment in hardware.c already said.
2009-02-07 17:07:52 +02:00
Lasse Collin bfd91198e4 Support LZMA_API_STATIC in assembler files to
avoid __declspec(dllexport) equivalent.
2009-02-07 15:55:47 +02:00
Lasse Collin 3306cf3883 Introduced LZMA_API_STATIC macro, which the applications
need to #define when linking against static liblzma on
platforms like Windows. Most developers don't need to
care about LZMA_API_STATIC at all.
2009-02-07 11:11:50 +02:00
Lasse Collin 75905a9afc Various code cleanups the the xz command line tool.
It now builds with MinGW.
2009-02-05 09:12:57 +02:00
Lasse Collin d0c0b9e94e Another utime() fix. 2009-02-03 12:15:17 +02:00
Lasse Collin ccf92a29e8 Fix wrong filename argument for utime() and utimes().
This doesn't affect most systems, since most systems
have better functions available.
2009-02-03 10:41:11 +02:00
Lasse Collin 99c1c2abfa Updated the x86 assembler code:
- Use call/ret pair to get instruction pointer for PIC.
  - Use PIC only if PIC or __PIC__ is #defined.
  - The code should work on MinGW and Darwin in addition
    to GNU/Linux and Solaris.
2009-02-02 21:19:01 +02:00
Lasse Collin 22a0c6dd94 Modify LZMA_API macro so that it works on Windows with
other compilers than MinGW. This may hurt readability
of the API headers slightly, but I don't know any
better way to do this.
2009-02-02 20:14:03 +02:00
Lasse Collin 8dd7b6052e Fix a bug in lzma_block_buffer_decode(), although this
function should be rewritten anyway.
2009-02-01 22:40:35 +02:00
Lasse Collin 55fd41431e Added initial version of raw buffer-to-buffer coding
functions, and cleaned up filter.h API header a little.
May be very buggy, not tested yet.
2009-02-01 22:39:07 +02:00
Lasse Collin 3e54ecee5c Fix missing newlines in xzdec.c. 2009-02-01 00:11:20 +02:00
Lasse Collin d64ca34f1b Use __cdecl also for function pointers in liblzma API when
on Windows.
2009-02-01 00:10:07 +02:00
Lasse Collin 6a2eb54092 Add LZMA_API to liblzma API headers. It's useful at least
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h
has to be #included separately where needed.
2009-01-31 11:01:48 +02:00
Lasse Collin d9993fcb4d Use _WIN32 instead of WIN32 in xzdec.c to test if compiling on Windows. 2009-01-31 10:13:09 +02:00
Lasse Collin 2dbdc5befb Fix two lines in lzma.h on which the # wasn't at the
beginning of the line.
2009-01-31 10:02:52 +02:00
Lasse Collin 4ab7601091 Add support for using liblzma headers in MSVC, which has no
stdint.h or inttypes.h.
2009-01-31 09:55:05 +02:00
Lasse Collin b2172cf823 Fix # -> ## in a macro in lzma.h. 2009-01-31 08:49:54 +02:00
Lasse Collin f54bcf6f80 Remove dangling crc64_init.c. 2009-01-30 00:29:58 +02:00
Lasse Collin 3241317093 Fix uninitialized variables in alone_decoder.c. This bug was
triggered by the previous commit, since these variables were
not used by anything before support for a preset dictionary.
2009-01-28 08:43:26 +02:00
Lasse Collin f76e39cf93 Added initial support for preset dictionary for raw LZMA1
and LZMA2. It is not supported by the .xz format or the xz
command line tool yet.
2009-01-27 18:36:05 +02:00
Lasse Collin 449b8c832b Regenerate the CRC tables without trailing blanks. 2009-01-26 20:09:17 +02:00
Jim Meyering 850f740042 remove trailing blanks from all but .xz files 2009-01-26 20:01:51 +02:00
Lasse Collin 667481f1aa Add lzma_block_buffer_decode(). 2009-01-26 14:34:10 +02:00
Lasse Collin 5fb34d8324 Add more sanity checks to lzma_stream_buffer_decode(). 2009-01-26 14:33:28 +02:00
Lasse Collin c129748675 Avoid hardcoded constant in easy.c. 2009-01-26 14:33:13 +02:00
Lasse Collin 1859d22d75 Tiny bit better sanity check in block_util.c 2009-01-26 13:06:49 +02:00
Lasse Collin 2c5fe958e4 Fix a dumb bug in Block decoder, which made it return
LZMA_DATA_ERROR with valid data. The bug was added in
e114502b2b.
2009-01-25 01:35:56 +02:00
Lasse Collin c81f13ff29 Added lzma_stream_buffer_decode() and made minor cleanups. 2009-01-23 22:27:50 +02:00
Lasse Collin 0b3318661c Fix a comment. 2009-01-22 12:53:33 +02:00
Lasse Collin 9ec80355a7 Add some single-call buffer-to-buffer coding functions. 2009-01-20 16:37:27 +02:00
