* re-enable Js build/test
* improve decoder performance
* rewrite dictionary data in Java/Js to a shorter uncompressed form
* improve dictionary generation tool
- 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
Add an option to avoid building shared libraries (for building with EMCC)
Drive-by:
* maven: ramp up java level to minimal required
* travis: replace deprecated clang-5.0 with clang-7
* maven: fallback to jdk10 to void javadoc bug
* Verbose CLI + start pulling "Shared-Brotli"
* vesbose CLI output; fix#666
* pull `SHIFT` transforms; currently this is semantically dead code;
later it will be used by "Shared-Brotli"
* Inverse bazel workspace tree.
Now each subproject directly depends on root (c) project.
This helps to mitigate Bazel bug bazelbuild/bazel#2391; short summary:
Bazel does not work if referenced subproject `WORKSPACE` uses any
repositories that embedding project does not.
Bright side: building C project is much faster;
no need to download closure, go and JDK...
Update
* make the zopflification aware of `NDIRECT`, `NPOSTFIX`
(better compression in `font` mode)
* add small and simple decoder tool
* fix typo
* Java: wrapper: make decoder channel more async-friendly
Ramp up version to 1.0.3 / 1.0.3
* 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.
Common:
* wrap dictionary data into `BrotliDictionary` structure
* replace public constant with getter `BrotliGetDictionary`
* reformat dictionary data
Decoder:
* adopt common changes
* clarify acceptable instance usage patterns
* hold reference to dictionary in state
Encoder:
* adopt common changes
* eliminate PIC spots in `CreateBackwardReferences`
* add per-chunk ratio guards for q0 and q1
* precompute relative distances to avoid repeated calculations
* prostpone hasher allocation/initialization
* refactor Hashers to be class-like structure
* further improvements for 1MiB+ inputs
* added new hasher type; made hashers more configurable
Java:
* Pull byte->int magic to `IntReader` from `BitReader`
* doxygenize and update API documentation
* fix spelling
* add "fuzz" corpus for java decoder to improve coverage
* use upper-case-snake names for dictionary constant definitions
* use `LDFLAGS` in conventional `Makefile`
