c94c6f80 2018-10-02 07:28:37 tools/brotli: improve window size autodetect (#710) Window size is defined as: `(1 << BROTLI_PARAM_LGWIN) - 16` in `c/include/brotli/encode.h` Therefore we should probably take these 16 bytes into account. Done basic manual testing: $ python3 -c 'print ("A"*2046)' > t $ bazel run -- //:brotli -w 0 -f -o $(realpath t).br $(realpath ./t) $ python3 research/brotlidump.py t.br |& fgrep WSIZE 0000 c1 1000001 WSIZE windowsize=(1<<12)-16=4080 New version properly detects window size of `4080`, while previous one used `2032`: $ python3 research/brotlidump.py t.br |& fgrep WSIZE 0000 b1 0110001 WSIZE windowsize=(1<<11)-16=2032
68db5c02 2018-04-13 11:44:34 Update (#660) * Update * improve q=1 compression on small files * fix "left shift before promotion" * fix osx Travis builds

631fe194 2018-03-20 17:37:41 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
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.
