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 eb12ec04 2018-06-20T15:14:10 Update (#688) * add rolling-composite-hasher for large-window mode * make API methods explicitly public
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.
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 3e58ea5f 2017-10-13T14:50:51 Update (#617) * remove `const` on `BrotliDictionary` members * extend `ZofliNode` distance range to 128MiB * add missing `port.h` include to `quality.h` * fix typo in encoder API-doc * regenerate `decode.min.js`
Tomáš Popela a0c7dafe 2017-10-10T11:24:13 Fix permissions of various files in project (#613) Move from 755 to 644.
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.
