a8f5813b | 2022-11-17 13:03:09 | Update Documentation: - add note that brotli is a "stream" format, not an archive-like - regenerate .1 with Pandoc Build: - drop legacy "BROTLI_BUILD_PORTABLE" option - drop "BROTLI_SANITIZED" definition Code: - c: comb includes - c/enc: extract encoder state into separate header - c/enc: drop designated q10 codepath - c/enc: dealing better with flushing of empty stream - fix MSVC compilation API: - py: use library version instead of one in version.h - c: add plugable API to report consumed input / produced output - c/java: support "lean" prepared dictionaries (without copy of source) | |

630b5084 | 2021-07-29 22:29:43 | Update (#914) * slimmer stack frames in encoder * fix MSAN problem in hasher_composite (not dangerous, only in large_window mode) * fix JNI decoder wrapper - power-of-two payloads fail to decode sometimes * reformat polyfil.js and decode_test.js | |
|
5692e422 | 2021-01-18 10:56:39 | Update (#852) * Update * comments and clarifications in block_splitter * power-of-2 aligned allocations for Hasher * refresh decode.js from Java sources * disable JS build | |
|
78e7bbc3 | 2019-05-03 11:51:11 | Update (#753) * fix executable mode of decode.js * explain clang-analyser about non-nullability * fix "dead assignment" * rename proguard.cfg -> proguard.pgcfg | |

4b2b2d4f | 2019-04-12 13:57:42 | Update (#749) Update: * Bazel: fix MSVC configuration * C: common: extended documentation and helpers around distance codes * C: common: enable BROTLI_DCHECK in "debug" builds * C: common: fix implicit trailing zero in `kPrefixSuffix` * C: dec: fix possible bit reader discharge for "large-window" mode * C: dec: simplify distance decoding via lookup table * C: dec: reuse decoder state members memory via union with lookup table * C: dec: add decoder state diagram * C: enc: clarify access to static dictionary * C: enc: improve static dictionary hash * C: enc: add "stream offset" parameter for parallel encoding * C: enc: reorganize hasher; now Q2-Q3 require exactly 256KiB to avoid global TCMalloc lock * C: enc: fix rare access to uninitialized data in ring-buffer * C: enc: reorganize logging / checks in `write_bits.h` * Java: dec: add "large-window" support * Java: dec: improve speed * Java: dec: debug and 32-bit mode are now activated via system properties * Java: dec: demystify some state variables (use better names) * Dictionary generator: add single input mode * Java: dec: modernize tests * Bazel: js: pick working commit for closure rules | |

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. | |
