git-svn-id: https://lz4.googlecode.com/svn/trunk@95 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
- New function : LZ4_decompress_safe_partial(), to decompress just enough data within a compressed block, saving CPU cycles
- New source files : lz4_decoder.h, lz4_encoder.h, lz4hc_encoder.h
- Improved speed of LZ4_decompress_fast()
- Improved speed for compression of small blocks < 64KB
- Improved speed for HC compression
git-svn-id: https://lz4.googlecode.com/svn/trunk@94 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
Added : LZ4c command-line utility, supporting the new streaming format
Added : xxhash library
Removed : lz4demo is now replaced by lz4.c
Removed : a few level 4 warnings (issue 64)
Updated : makefiles
git-svn-id: https://lz4.googlecode.com/svn/trunk@92 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
- Improved decoding speed, even more for 64-bits, and "safe" version
- Slight speed increase for LZ4-HC
- Pushed a useless parameter down the list in lz4.c

Fuzzer : more tests cases
lz4demo : detect write errors. Thanks to Dima Tisnek
bench.c : compatibility with Solaris 64. Thanks to Thorbjørn Willoch
LZ4_compressBound() : now both in inline function and macro format. Thanks to Jacob Gorm Hansen
git-svn-id: https://lz4.googlecode.com/svn/trunk@84 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
Corrected issue 40 : Detect early ending of compressed stream. Thanks Adrian Grand.
Corrected issue 41 : minor comment editing on lz4.h
git-svn-id: https://lz4.googlecode.com/svn/trunk@82 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
- Added : a fuzzer tool
Thanks to Andrew Mahone, for contribution on both points
git-svn-id: https://lz4.googlecode.com/svn/trunk@79 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
Removed : functions with explicit *ctx management (LZ4_compressCtx & LZ4_compress64kCtx). Functions are still present in the .c
Changed : LZ4_compressBound() now a macro
git-svn-id: https://lz4.googlecode.com/svn/trunk@71 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
Fixed : LZ4_uncompress_unknownOutputSize(), now protected against a malicious attack type, where a crafted input deliberately attempts to make it read outside of input buffer. Thanks Steinar H. Gunderson for report.
git-svn-id: https://lz4.googlecode.com/svn/trunk@58 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
Added : new tuning parameter : LZ4_COMPRESSMIN. Thanks to Maciej Adamczyk for suggestion.
changed : macro for bswap16, in order to help GCC intrinsic detection. Thank to Erik Andersen for suggestion.
git-svn-id: https://lz4.googlecode.com/svn/trunk@57 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
Corrected : ARM compilation under Visual Studio : now generates cautious code, like GCC, to ensure compatibility with strict-align CPUs. Thanks to Joe WoodBury.
Minor : bench.c : Hash verification changed to MurmurHash3A
Minor : bench.c : selectable block size
git-svn-id: https://lz4.googlecode.com/svn/trunk@56 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
corrected : bench.c now correctly detects file size on a wider ranger of compilers; thanks to Erik Andersen
minor : removed warnings on undefined (-Wundef on gcc), thanks David Sterba for suggestion
git-svn-id: https://lz4.googlecode.com/svn/trunk@55 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
LZ4Demo : correction : produces compatible streams on both big-endian and little-endian systems
git-svn-id: https://lz4.googlecode.com/svn/trunk@52 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
Decoding functions are now also immune to out-of-buffer read errors (note : they were already protected against malicious out-of-buffer write attacks)
