Eugene Kliuchnikov 68f1b90a 2021-08-18T19:15:07 Update (#918) Prepare to use copybara worklow.
Eugene Kliuchnikov 7f740f13 2020-05-15T11:06:21 Update (#807) - fix formatting - fix type conversion - fix no-op arithmetic with null-pointer - improve performance of hash_longest_match64 - go: detect read after close - java decoder: support compound dictionary - remove executable flag on non-scripts
Eugene Kliuchnikov 631fe194 2018-03-20T17:37:41 Update (#651) * fix `bazel` build (ignore switch case fall-through) * add `NPOSTFIX` / `NDIRECT` encoder parameters * fix source file lists (add `params.h`) * fix bug in `durchschlag` * print clarifying messages wheb CLI argument parsing fails
Eugene Kliuchnikov 35e69fc7 2018-02-26T09:04:36 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.
