Lasse Collin 9595a3119b liblzma: Add optional autodetection of LZMA end marker.
Turns out that this is needed for .lzma files as the spec in
LZMA SDK says that end marker may be present even if the size
is stored in the header. Such files are rare but exist in the
real world. The code in liblzma is so old that the spec didn't
exist in LZMA SDK back then and I had understood that such
files weren't possible (the lzma tool in LZMA SDK didn't
create such files).

This modifies the internal API so that LZMA decoder can be told
if EOPM is allowed even when the uncompressed size is known.
It's allowed with .lzma and not with other uses.

Thanks to Karl Beldan for reporting the problem.

Lasse Collin 3a0c5378ab Docs: Add new example programs.
These have more comments than the old examples and

Lasse Collin 1bd2c2c553 Docs: Move xz_pipe_comp.c and xz_pipe_decomp.c to doc/examples_old.
It is good to keep these around to so that if someone has
copied the decompressor bug from xz_pipe_decomp.c he has
an example how to easily fix it.

Spot candidates by running these commands:

    -e 'while (/\b(then?|[iao]n|i[fst]|but|f?or|at|and|[dt]o)\s+\1\b/gims)' \
    -e '{$n=($` =~ tr/\n/\n/ + 1); ($v=$&)=~s/\n/\\n/g; print "$ARGV:$n:$v\n"}'

Thanks to Jim Meyering for the original patch.

Lasse Collin bab0f01ed9 Add two simple example programs.
Hopefully these help a bit when learning the basics
of liblzma API. I plan to write detailed examples about
both basic and advanced features with lots of comments,
but these two examples are good have right now.

The examples were written by Daniel Mealha Cabrita. Thanks.

Lasse Collin 982da7ed31 The .xz file format specification version 1.0.0 is now
officially released. The format has been technically the same
since 2008-11-19, but now that it is frozen, people can start
using it without a fear that the format will break.

Lasse Collin bceb3918db Put the file format specification into the public domain.
Same will be done to the actual code later.

Lasse Collin e114502b2b Oh well, big messy commit again. Some highlights:
- Updated to the latest, probably final file format version.
  - Command line tool reworked to not use threads anymore.
    Threading will probably go into liblzma anyway.
  - Memory usage limit is now about 30 % for uncompression
    and about 90 % for compression.
  - Progress indicator with --verbose
  - Simplified --help and full --long-help
  - Upgraded to the last LGPLv2.1+ getopt_long from gnulib.
  - Some bug fixes

that the existing code will change a lot.

Lasse Collin bc0b945ca3 Tiny non-technical edits to file-format.txt. 2008-01-16 16:33:37 +02:00
Lasse Collin 4e7e54c4c5 Introduced compatibility with systems that have pre-C99
or no inttypes.h. This is useful when the compiler has
good enough support for C99, but libc headers don't.

Changed liblzma API so that sys/types.h and inttypes.h
have to be #included before #including lzma.h. On systems
that don't have C99 inttypes.h, it's the problem of the
applications to provide the required types and macros
before #including lzma.h.

If lzma.h defined the missing types and macros, it could
conflict with third-party applications whose configure
has detected that the types are missing and defined them
in config.h already. An alternative would have been
introducing lzma_uint32 and similar types, but that would
just be an extra pain on modern systems.
