Oodle Development History
This change log includes the Oodle development history.
Release 2.6.0 - Feb 27, 2018
- new : new compressor Leviathan !!
- new : new API Oodle_SetUsageWarnings ; usage warnings are on by default
- new : OodlePlugin_Printf_Verbose added; can be installed in Oodle Core via OodlePlugins_SetPrintf
- enhancement : Kraken & Mermaid optimal levels now get more compression (chunk adaptation & TLL parse)
- enhancement : Mermaid optimal levels now get more compression on some files (costing of entropy offsets)
- enhancement : Kraken & Mermaid generally achieve better space-speed with the >= 2.6.0 bit stream changes (smaller sizes and/or faster to decode)
- enhancement : Kraken, Mermaid & Selkie fast levels are now much faster to encode! (especially SuperFast and VeryFast)
- warning : DEPRECATION : Oodle compressors that predate Kraken are being gradually deprecated. (eg. LZH, LZNA, etc.) You should always be encoding with compressors from the new Kraken family (Kraken, Mermaid, Selkie, Leviathan, Hydra). Old decompressors will be supported for the forseeable future, so old data will still be loaded but the encoders will be removed in some future version. Attempts to encode with outdated compressors is now logged as an Oodle Usage Warning. This can be disabled with Oodle_SetUsageWarnings. The OodleLZ_Compressor enums for the old codecs are now hidden; you must define OODLE_ALLOW_DEPRECATED_COMPRESSORS before including oodle2.h to get them.
- change : WARNING Kraken & Mermaid data made by 2.6.0 by default cannot be loaded by Oodle 2.5 and earlier ; set m_OodleLZ_BackwardsCompatible_MajorVersion if you need that. Oodle can always load data made by previous versions, but the reverse is not necessarily true.
- change : OodleLZ_Small_Buffer_LZ_Fallback_Size default value changed to 0 so it never happens unless the client modifies this value to something larger.
- change : example_lz : added lz_test_12 showing in place decoding
- change : Hydra can select Leviathan. Hydra-compressed data cannot be loaded by Oodle 2.5 and earlier because they don't contain Leviathan. To use Hydra to make data compatible with previous versions, set m_OodleLZ_BackwardsCompatible_MajorVersion.
- change : OodleLZ_Compress API change , added scratch memory arguments so client can pass in pre-allocated memory to eliminate internal Oodle alloc calls. (non-optimal levels only in the new compressor family; optimal levels & old compressors will still do allocations even if scratch is provided)
- change : fix name of enums to match OodleX convention : OodleLog_VerboseLevel renamed to OodleXLog_VerboseLevel , OodleLog_StateFlags renamed to OodleXLog_StateFlags
- change : secret level 8 (OodleLZ_CompressionLevel_Optimal4) is now public ; no longer modifies compress options or changes space-speed tradeoff target
- change : OodleLZ_CompressionLevel_Optimal4 Mermaid & Kraken higher compression optimal parse
- change : Oodle for Switch is now built with SDK 3.4
- change : OodleHuffman_EncodeArrayU8 takes scratch memory argument to avoid internal allocation
- change : OodleXLZ_Decompress_ThreadPhased_Narrow_Async takes scratch memory argument to avoid internal allocation
- change : OodleLZ_Decompress API : default argument value of OodleLZ_FuzzSafe_No removed; recommend passing OodleLZ_FuzzSafe_Yes
- change : OodleXLZ_ReadAndDecompress_Stream_Async API : added decBufBase argument
- change : OodleLZ_CompressOptions_GetDefault at level 8 was returning a lower spaceSpeedTradeoffBytes ; don't do that anymore, the default is always 256 ; decode speed is mostly independent of compression level.
- obsolescence : EASTL is no longer used
- deprecation : old OodleLZ_CompressionLevel_RLE removed
- deprecation : OodleX OOZ functions removed (OodleXLZ_Compress_WriteOOZ_Async, etc)
- deprecation : OodleXLZ_Decompress_ThreadPhased_Wide_Async removed
- fix : Mermaid/Selkie : some of the non-optimal encode levels were not respecting the dictionarySize option to limit the match window
- fix : Kraken/Mermaid/Selkie didn't support CompressionLevel_None correctly. They now pass through data uncompressed at that level.
- fix : Kraken/Mermaid/Selkie decoders had some potential fuzz safety violations (long matches at end of buffer)
- fix : OodleHuffman_DecodeArrayU8 wasn't doing CPU detection; it was slower than it should be if you didn't call other Oodle functions
- fix : the OodleXLZ_Compress_WriteOOZ family of functions took seekChunkLen as both as a function argument and via the OodleLZ_CompressOptions , creating a potential for mismatch ; the function argument is now removed.
- fix : Mermaid encoder was not putting backwards compatible streams correctly for version 3 compatibility (was always making streams for version >= 2.4.0)
- fix : Mermaid/Selkie encoder could overrun compressed buffer beyond OodleLZ_GetCompressedBufferSizeNeeded on some blocks. In parallel encoding mode this could cause corrupted compressed streams.
- fix : OodleXLZ_Decompress_ThreadPhased_Narrow_Async had a race in its finalization that could cause a read from freed memory
- fix : OodleLZDecoder_DecodeSome was incorrectly returning false when compAvail was too small to parse the first header (typically < 16 bytes); now returns true with no progress
- fix : OodleLZ_Decompress could return -1 for failure; it should always return 0 for failure (OODLELZ_FAILED); check <= 0 in previous versions
Release 2.5.5 - August 22, 2017
- fix : A bug in the Kraken & Mermaid encoders was introduced in Oodle 2.5.0 ; any data encoded with Kraken or Mermaid from Oodle 2.5.0 - 2.5.4 should be checked for correct decompression and re-encoded if needed. Those versions may have made data which will fail to decode, or might claim to succeed decoding but produce bad bytes. The cause was that huff streams in the encoder could collide and overwrite each other without detection. This was most likely in whole-huff chunks at 128k boundaries, on trinary-aligned data (such as RGB BMP data). This was more likely with m_OodleLZ_BackwardsCompatible_MajorVersion <= 2 but could happen in other cases.
Release 2.5.4 - August 8, 2017

- fix : remove alloca use in rrHuffman that could cause crash on threads with small stack size on Linux
Release 2.5.2 - May 25, 2017
- fix : Kraken decoder had a bug that caused it to incorrectly return failure on valid compressed chunks (due to the header corruption check not counting the scratch space needed with correct accounting of the thread phasing header) - NOTE this change means OodleLZDecoder_MemorySizeNeeded is slightly larger now
- fix : fix handle leak in OodleXLZ_Compress_WriteOOZFile_AsyncAndWait when file open failed

- enhancement : Mermaid & Selkie encoding improved (faster and better ratio) on buffers <= 64k bytes long

- change : Xbox One build is made with March 2017 XDK , still VC 2012 (but VC 2015 compatible)

- obsolescence : libdivsufsort is no longer used
Release 2.5.0 - April 20, 2017
- new : OodleHuffman_EncodeArrayU8 and OodleHuffman_DecodeArrayU8 reintroduced as public APIs. (not compatible with old public Huffman API)

Release 2.4.3 - February 14, 2017
- fix : Mermaid & Selkie encoders could cause an access violation reading past the end of the raw buffer if the length was just over 64k mod 128k
- fix : Some compressors failed to decode files that were (128k+1)mod 256k bytes long due to bug in fuzz safety checks
- fix : Selkie encoder was incorrectly choosing offset compression in some cases, causing slower decodes

- fix : rename OodleLog_Printf macro to OodleXLog_Printf to match OodleX lib naming convention
- fix : LZB16 decoder crashed on 32-bit ARM Android. LZB16 was also used as the fallback for tiny buffers in Kraken/Mermaid/Selkie/Hydra.

- new : OodleX_ReleaseThreadTLS function to release OodleX TLS resources in the rare usage that you churn through a huge number of thread creates and destroys
- change : Clean up the behavior of OodleLZ_GetCompressedStepForRawStep when it is not given the entire compressed data; now returns -1 for error and 0 for not enough data.
- fix : Fix race in the OodleThinSemaphore used in the example code via OodleX_Semaphore_Post; this was only used by example_lz_threadphased , so should not affect any production code
- fix : Out of memory default handler would just infinite busy-loop on fgetc on non-Windows platforms
