2a5a088b | 2023-08-21 06:35:47 | more tuning for BROTLI_EXPERIMENTAL + clean-on-oom PiperOrigin-RevId: 558771745 | |
|
3ebb2d30 | 2023-08-18 02:55:01 | Move serialized dictionary feature behind the flag. BROTLI_SHARED_DICTIONARY_SERIALIZED enum value is a part of API, but it should not be used (will cause failures). Changing how serialized dictionaries work won't be considered as an API change, until this feature is enabled. Enabling this feature in the future will be considered as a "compatible" change.

35e69fc7 | 2018-02-26 09:04:36 | New feature: "Large Window Brotli" (#640) * New feature: "Large Window Brotli" By setting special encoder/decoder flag it is now possible to extend LZ-window up to 30 bits; though produced stream will not be RFC7932 compliant. Added new dictionary generator - "DSH". It combines speed of "Sieve" and quality of "DM". Plus utilities to prepare train corpora (remove unique strings). Improved compression ratio: now two sub-blocks could be stitched: the last copy command could be extended to span the next sub-block. Fixed compression ineffectiveness caused by floating numbers rounding and wrong cost heuristic. Other C changes: - combined / moved `context.h` to `common` - moved transforms to `common` - unified some aspects of code formatting - added an abstraction for encoder (static) dictionary - moved default allocator/deallocator functions to `common` brotli CLI: - window size is auto-adjusted if not specified explicitly Java: - added "eager" decoding both to JNI wrapper and pure decoder - huge speed-up of `DictionaryData` initialization * Add dictionaryless compressed dictionary * Fix `sources.lst` * Fix `sources.lst` and add a note that `libtool` is also required. * Update setup.py * Fix `EagerStreamTest` * Fix BUILD file * Add missing `libdivsufsort` dependency * Fix "unused parameter" warning. | |
