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.

Thanks to Jonathan Nieder.

Lasse Collin 3a0c5378ab Docs: Add new example programs. 
These have more comments than the old examples and
human-readable error messages. More tutorial-like examples
are needed but these are a start.

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.

Lasse Collin 3e321a3acd Remove doubled words from documentation and comments. 
Spot candidates by running these commands:
  git ls-files |xargs perl -0777 -n \
    -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.
 2009-01-28 17:16:38 +02:00
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

a lot simpler than the previous versions, but it also means
that the existing code will change a lot.
