1) Use a tighter upper bound on the Huffman table size.
2) Remove unused argument len in ToUpperCase.
3) Remove unused no-op assignment in BrotliDecompress.
4) Fix include guard name.
This commit contains a batch of changes that were made to the Brotli
compression algorithm in the last month. Most important changes:
* Format change: don't push distances representing static dictionary words to the distance cache.
* Fix decoder invalid memory access bug caused by building a non-complete Huffman tree.
* Add a mode parameter to the encoder interface.
* Use different hashers for text and font mode.
* Add a heuristics to the hasher for skipping non-compressible data.
* Exhaustive search of static dictionary during backward reference search.
This commit contains a batch of changes that were made to the Brotli
compression algorithm in the last month. Most important changes:
* Fixes to the spec.
* Change of code length code order.
* Use a 2-level Huffman lookup table in the decoder.
* Faster uncompressed meta-block decoding.
* Optimized encoding of the Huffman code.
* Detection of UTF-8 input encoding.
* UTF-8 based literal cost modeling for improved
backward reference selection.
This change removes the redundant HCLEN, HLENINC and HLEN
fields from the encoding of the complex Huffman codes and
derives these from an invariant of the code length sequence.
Based on a patch by Robert Obryk.
This commit contains a batch of changes that were made to the Brotli
compression algorithm in the last month. Most important changes:
* Updated spec
* Changed Huffman code length alphabet to use run length codes more
efficiently, based on a suggestion by Robert Obryk
* Changed encoding of the number of Huffman code lengths (HLEN)
* Changed encoding of the number of Huffman trees (NTREES)
* Added support for uncompressed meta-blocks
This commit contains a batch of changes that were made to the Brotli
compression algorithm in the last three weeks. Most important changes:
* Added UTF8 context model for good text compression.
* Simplified context modeling by having only 4 context modes.
* Per-block context mode selection.
* Faster backward copying and bit reading functions.
* More efficient histogram coding.
* Streaming support for the decoder and encoder.
(1) Move all variable declarations to the beginning of the block.
(2) Remove 'z' printf modifiers.
(3) Fix 'comma at the end of enumeration list' warning.
