c3540e2b 2015-08-10 18:01:29 [setup.py] use MSVC 10.0 when compiling for Windows Python 2.7 Python 2.7 for Windows is compiled using MS Visaul C++ 9.0 (Visual Studio 2008). However the latter does not support many modern C++ features which are required to compile the Brotli encoder. So we monkey-patch distutils to always look for MSVC version 10.0 instead of 9.0.

67d26e0d 2015-06-12 16:55:09 Merge pull request #119 from szabadka/master Deprecate greedy_block_split and enable_context_modeling brotli params.
618287b3 2015-06-12 16:50:49 Deprecate greedy_block_split and enable_context_modeling brotli params. These affected only quality 11, and now it does not make sense to disable block splitting or context modeling because most of the time is spent in zopfli anyway. Now all speed vs size compromises are controlled by the quality param.
981ca6e5 2015-06-12 16:47:56 Merge pull request #118 from szabadka/master Use a static hash table to look up dictionary words and transforms.
66098830 2015-06-12 16:45:17 Use a static hash table to look up dictionary words and transforms. This is used for quality 11, for qualities <= 9 we already have a simpler hash table. The static data size is 252 kB, and this removes the need to initialize a huge hash map at startup, which was the reason why transforms had to be disabled by default. In comparison, the static dictionary itself is 120 kB. This supports every transform, except the kOmitFirstN.
0fd2df4f 2015-06-12 16:37:17 Merge pull request #117 from szabadka/master Add "zopfli"-style backward reference search to brotli.
b3d3723f 2015-06-12 16:25:41 Add "zopfli"-style backward reference search to brotli. This commit adopts the backward reference search algorithm from the zopfli project (see https://github.com/google/zopfli) to brotli. This slower backward reference search is run only in quality 11 and it runs two iterations of entropy cost modeling and shortest path search. As a result, the original backward reference search function can be simplified a bit, since we can remove some heuristics that were replaced with the zopfli-style search.
94b33769 2015-06-12 16:16:04 Merge pull request #116 from szabadka/master Change the static dictionary hash table to take into account word frequency when there are hash collisions.

a0d0ecfe 2015-06-12 16:12:38 Merge pull request #115 from szabadka/master Bug fixes for the brotli encoder.
65f3fc55 2015-06-12 16:11:50 Bug fixes for the brotli encoder. * Fix an out-of-bounds access to depth_histo in the bit cost calculation function. * Change type of distance symbol to uint16_t in block splitter, because if all postfix bits are used, there can be 520 distance symbols. * Save the distance cache between meta-blocks at the correct place. This fixes a roundtrip failure that can occur when there is an uncompressed metablock between two compressed metablocks. * Fix a bug when setting lgwin to 24 in the encoder parameters It ended up making metablocks larger than 24 bits in size. * Fix out-of-bounds memory accesses in parallel encoder. CreateBackwardReferences can read up to 4 bytes past end of input if the end of input is before mask. * Add missing header for memcpy() in port.h
a13ea018 2015-06-12 15:45:41 Merge pull request #114 from szabadka/master Brotli custom LZ77 dictionary support.
b43df8f6 2015-06-12 15:43:54 Brotli custom LZ77 dictionary support. Adds functions to prepend such dictionary to the encoder and decoder, and twiddles their internal parameters to do as if that was a previous part of the input. This dictionary is just a prefilled LZ77 window, it is not related to the built in transformable brotli dictionary.
631184d4 2015-06-12 15:32:31 Merge pull request #113 from szabadka/master Speedups to brotli quality 11.
667f70ad 2015-06-12 15:29:06 Speedups to brotli quality 11. * Cluster at most 64 histograms at a time in the first round of clustering. * Use a faster histogram cost estimation function. * Don't compute the log2(total) multiple times in the block splitter.
af09ee73 2015-06-12 15:14:13 Merge pull request #112 from szabadka/master Speedups and fixes to the decoder.
641bc158 2015-06-12 15:12:23 Speedups and fixes to the decoder. * Read data by 4-byte runs. This resolves unaligned read (Bus error) on arm-android. * Get rid of malloc/free in BrotliBuildHuffmanTable. * Tweak order of instructions when reading Huffman codes.
