2012-07-17liblzma: Make the use of lzma_allocator const-correct.Lasse Collin1-4/+4
There is a tiny risk of causing breakage: If an application assigns lzma_stream.allocator to a non-const pointer, such code won't compile anymore. I don't know why anyone would do such a thing though, so in practice this shouldn't cause trouble. Thanks to Jan Kratochvil for the patch.
2011-05-17Add underscores to attributes (__attribute((__foo__))).Lasse Collin1-1/+1
2010-05-26Rename MIN() and MAX() to my_min() and my_max().Lasse Collin1-3/+4
This should avoid some minor portability issues.
2009-11-15Fix wrong indentation caused by incorrect settingsLasse Collin1-9/+9
in the text editor.
2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin1-12/+5
Some minor documentation cleanups were made at the same time.
2009-01-27Added initial support for preset dictionary for raw LZMA1Lasse Collin1-10/+25
and LZMA2. It is not supported by the .xz format or the xz command line tool yet.
2008-12-15The LZMA2 decoder fix introduced a bug to LZ decoder,Lasse Collin1-10/+23
which made LZ decoder return too early after dictionary reset. This fixes it.
2008-12-15Fix data corruption in LZMA2 decoder.Lasse Collin1-1/+16
2008-09-13LZ decoder cleanupLasse Collin1-3/+2
2008-09-13Renamed constants:Lasse Collin1-1/+1
- LZMA_VLI_VALUE_MAX -> LZMA_VLI_MAX - LZMA_VLI_VALUE_UNKNOWN -> LZMA_VLI_UNKNOWN - LZMA_HEADER_ERRRO -> LZMA_OPTIONS_ERROR
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin1-373/+174
broken. API has changed a lot and it will still change a little more here and there. The command line tool doesn't have all the required changes to reflect the API changes, so it's easy to get "internal error" or trigger assertions.
2008-06-18Update the code to mostly match the new simpler file formatLasse Collin1-3/+3
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.
2008-03-11Initialize the last byte of the dictionary to zero so thatLasse Collin1-0/+1
lz_get_byte(lz, 0) returns zero. This was broken by 1a3b21859818e4d8e89a1da99699233c1bfd197d.
2008-03-10Always initialize lz->temp_size in lz_decoder.c. temp_size didLasse Collin1-5/+6
get initialized as a side-effect after allocating a new decoder, but not when the decoder was reused.
2008-02-02Don't memzero() the history buffer when initializing LZLasse Collin1-4/+3
decoder. There's no danger of information leak here, so it isn't required. Doing memzero() takes a lot of time with large dictionaries, which could make it easier to construct DoS attack to consume too much CPU time.
