Evgenii Kliuchnikov a8f5813b 2022-11-17T13:03:09 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)
Eugene Kliuchnikov 4b2b2d4f 2019-04-12T13:57:42 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
Eugene Kliuchnikov f5ed35d0 2018-05-03T11:16:21 Update (#664) * Update * fix ifdef style * get back to fine-compiler-version-based-macros (use Hedley) * fix q=0 histogram collection for very long copy/insert commands
Eugene Kliuchnikov 0f3c84e7 2018-03-27T22:29:22 Update (#656) * proper fix for the "fall through" warning" * automatic NDIRECT/NPOSTFIX tuning (better compression) * fix unaligned access for `aarch64`-cross-`armhf` build * fix `aarch64` detection (10% decoder speedup) * expose `large_window` CLI option * make default window size 16MiB * ramp up version to 1.0.4
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.
Eugene Kliuchnikov da254cff 2017-12-12T14:33:12 Update (#630) * merge {dec|enc}/port.h into common/platform.h * fix one-shot q=10 1-byte input compression * fix some unprefixed definitions * make hashers host-endianness-independent * extract enc/params.h from enc/quality.h * fix API documentation / typos * improve `BrotliEncoderMaxCompressedSize`
Eugene Kliuchnikov d63e8f75 2017-08-04T10:02:56 Update API, and more (#581) Update API, and more: * remove "custom dictionary" support * c/encoder: fix #580: big-endian build * Java: reduce jar size * Java: speedup decoding * Java: add 32-bit CPU support * Java: make source code JS transpiler-ready
Eugene Kliuchnikov 6ece1d87 2017-04-23T14:07:08 Move files & update paths (#541) * Move files & update paths * Rename build to scripts. * Fix paths * Fix script.
