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.

e79c42d854 Fix off-by-one in LZ decoder. 
Fortunately, this bug had no security risk other than accepting
some corrupt files as valid.

390e69887f Fix wrong macro names in lc_cpucores.m4 and cpucores.h. 
Thanks to Bert Wesarg.

fd6a380f4e Add a rough explanation of --extreme to output of --help. 2009-02-22 19:07:54 +02:00

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.

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.

7494816ab0 Make physmem.h work on old Windows versions. 
Thanks to Hongbo Ni for the original patch.

11ae4ae35f Fix microsecond vs. nanosecond confusion in my_time(). 2009-02-14 20:44:52 +02:00

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.

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.

1d924e584b Fix handling of integrity check type in the xz command line tool. 2009-02-13 17:30:30 +02:00

96c46df7de Improve support for DOS-like systems. 
Here DOS-like means DOS, Windows, and OS/2.

a3bbbe05d3 Let the user specify custom CFLAGS on the make command 
line. Previously custom CFLAGS worked only when they were
passed to configure.

53f7598998 Fix aliasing issue in physmem.h. 2009-02-08 21:35:11 +02:00

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.

ae1ad9af54 Make "xz --force" to write to terminal as the error 
message suggests.

79e25eded4 Support both slash and backslash as path component 
separator on Windows when parsing argv[0].

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.

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

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.

75905a9afc Various code cleanups the the xz command line tool. 
It now builds with MinGW.

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

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.

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.

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.

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.

d9993fcb4d Use _WIN32 instead of WIN32 in xzdec.c to test if compiling on Windows. 2009-01-31 10:13:09 +02:00

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

b2172cf823 Fix # -> ## in a macro in lzma.h. 2009-01-31 08:49:54 +02:00

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.

2c5fe958e4 Fix a dumb bug in Block decoder, which made it return 
LZMA_DATA_ERROR with valid data. The bug was added in
e114502b2b.
