literal coder as part of the main LZMA encoder or
decoder structure.
Make the LZMA decoder to rely on the current internal API
to free the allocated memory in case an error occurs.
specification. Simplify things by removing most of the
support for known uncompressed size in most places.
There are some miscellaneous changes here and there too.
The API of liblzma has got many changes and still some
more will be done soon. While most of the code has been
updated, some things are not fixed (the command line tool
will choke with invalid filter chain, if nothing else).
Subblock filter is somewhat broken for now. It will be
updated once the encoded format of the Subblock filter
has been decided.
misunderstanding of the code. There's no tiny fix for this
problem, so I also cleaned up the code in general.
This reduces the speed of the encoder 2-5 % in the fastest
compression mode ("lzma -1"). High compression modes should
have no noticeable performance difference.
This commit breaks things (especially LZMA_SYNC_FLUSH) but I
will fix them once the new format and LZMA2 has been roughly
implemented. Plain LZMA won't support LZMA_SYNC_FLUSH at all
and won't be supported in the new .lzma format. This may
change still but this is what it looks like now.
Support for known uncompressed size (that is, LZMA or LZMA2
without EOPM) is likely to go away. This means there will
be API changes.
pass -std=gnu99 instead of -std=c99 to GCC now, but -pedantic
should still give warnings about GNU extensions like before
except with some special keywords like asm().
size. The "fix" breaks LZMA_SYNC_FLUSH at end of stream
with known uncompressed size, but since it currently seems
likely that support for encoding with known uncompressed
size will go away anyway, I'm not fixing this problem now.
once we have a stable release (won't be very soon). The
version number is no longer related to version of LZMA SDK.
Made some small Automake-related changes to toplevel
Makefile.am and configure.ac.
word literal instead of char for better consistency.
There are still some names with _char instead of _literal
in lzma_optimum, these may be changed later.
Renamed length coder variables.
This commit doesn't change the program logic.
lzma_encoder_init.c. While we don't call
fill_distances_prices() and fill_align_prices() in
lzma_lzma_encoder_init(), we still need to initialize
these two variables so that the fill functions get
called in lzma_encoder_getoptimum.c in the beginning
of a stream.
