### Introduction
|
||||||
|
|
||||||
|
Brotli is a generic-purpose lossless compression algorithm that compresses data
|
||||||
|
using a combination of a modern variant of the LZ77 algorithm, Huffman coding
|
||||||
|
and 2nd order context modeling, with a compression ratio comparable to the best
|
||||||
|
currently available general-purpose compression methods. It is similar in speed
|
||||||
|
with deflate but offers more dense compression.
|
||||||
|
|
||||||
|
The specification of the Brotli Compressed Data Format is defined in [RFC 7932](https://www.ietf.org/rfc/rfc7932.txt).

/* Lookup table to map the previous two bytes to a context id.
|
||||||
|
|
||||||
|
There are four different context modeling modes defined here:
|
||||||
|
CONTEXT_LSB6: context id is the least significant 6 bits of the last byte,
|
||||||
|
CONTEXT_MSB6: context id is the most significant 6 bits of the last byte,
|
||||||
|
CONTEXT_UTF8: second-order context model tuned for UTF8-encoded text,
|
||||||
|
CONTEXT_SIGNED: second-order context model tuned for signed integers.
|
||||||
|
|
||||||
|
The context id for the UTF8 context model is calculated as follows. If p1
|
||||||
|
and p2 are the previous two bytes, we calculate the context as
|
||||||
|
|
||||||
|
context = kContextLookup[p1] | kContextLookup[p2 + 256].
|
||||||
|
|
||||||
|
If the previous two bytes are ASCII characters (i.e. < 128), this will be
|
||||||
|
equivalent to
|
||||||
|
|
||||||
|
context = 4 * context1(p1) + context2(p2),
|
||||||
|
|
||||||
|
where context1 is based on the previous byte in the following way:
|
||||||
|
|
||||||
|
0 : non-ASCII control
|
||||||
|
1 : \t, \n, \r
|
||||||
|
2 : space
|
||||||
|
3 : other punctuation
|
||||||
|
4 : " '
|
||||||
|
5 : %
|
||||||
|
6 : ( < [ {
|
||||||
|
7 : ) > ] }
|
||||||
|
8 : , ; :
|
||||||
|
9 : .
|
||||||
|
10 : =
|
||||||
|
11 : number
|
||||||
|
12 : upper-case vowel
|
||||||
|
13 : upper-case consonant
|
||||||
|
14 : lower-case vowel
|
||||||
|
15 : lower-case consonant
|
||||||
|
|
||||||
|
and context2 is based on the second last byte:
|
||||||
|
|
||||||
|
0 : control, space
|
||||||
|
1 : punctuation
|
||||||
|
2 : upper-case letter, number
|
||||||
|
3 : lower-case letter
|
||||||
|
|
||||||
|
If the last byte is ASCII, and the second last byte is not (in a valid UTF8
|
||||||
|
stream it will be a continuation byte, value between 128 and 191), the
|
||||||
|
context is the same as if the second last byte was an ASCII control or space.
|
||||||
|
|
||||||
|
If the last byte is a UTF8 lead byte (value >= 192), then the next byte will
|
||||||
|
be a continuation byte and the context id is 2 or 3 depending on the LSB of
|
||||||
|
the last byte and to a lesser extent on the second last byte if it is ASCII.
|
||||||
|
|
||||||
|
If the last byte is a UTF8 continuation byte, the second last byte can be:
|
||||||
|
- continuation byte: the next byte is probably ASCII or lead byte (assuming
|
||||||
|
4-byte UTF8 characters are rare) and the context id is 0 or 1.
|
||||||
|
- lead byte (192 - 207): next byte is ASCII or lead byte, context is 0 or 1
|
||||||
|
- lead byte (208 - 255): next byte is continuation byte, context is 2 or 3
|
||||||
|
|
||||||
|
The possible value combinations of the previous two bytes, the range of
|
||||||
|
context ids and the type of the next byte is summarized in the table below:
|
||||||
|
|
||||||
|
|--------\-----------------------------------------------------------------|
|
||||||
|
| \ Last byte |
|
||||||
|
| Second \---------------------------------------------------------------|
|
||||||
|
| last byte \ ASCII | cont. byte | lead byte |
|
||||||
|
| \ (0-127) | (128-191) | (192-) |
|
||||||
|
|=============|===================|=====================|==================|
|
||||||
|
| ASCII | next: ASCII/lead | not valid | next: cont. |
|
||||||
|
| (0-127) | context: 4 - 63 | | context: 2 - 3 |
|
||||||
|
|-------------|-------------------|---------------------|------------------|
|
||||||
|
| cont. byte | next: ASCII/lead | next: ASCII/lead | next: cont. |
|
||||||
|
| (128-191) | context: 4 - 63 | context: 0 - 1 | context: 2 - 3 |
|
||||||
|
|-------------|-------------------|---------------------|------------------|
|
||||||
|
| lead byte | not valid | next: ASCII/lead | not valid |
|
||||||
|
| (192-207) | | context: 0 - 1 | |
|
||||||
|
|-------------|-------------------|---------------------|------------------|
|
||||||
|
| lead byte | not valid | next: cont. | not valid |
|
||||||
|
| (208-) | | context: 2 - 3 | |
|
||||||
|
|-------------|-------------------|---------------------|------------------|
|
||||||
|
|
||||||
|
The context id for the signed context mode is calculated as:
|
||||||
|
|
||||||
|
context = (kContextLookup[512 + p1] << 3) | kContextLookup[512 + p2].
|
||||||
|
|
||||||
|
For any context modeling modes, the context ids can be calculated by |-ing
|
||||||
|
together two lookups from one table using context model dependent offsets:
|
||||||
|
|
||||||
|
context = kContextLookup[offset1 + p1] | kContextLookup[offset2 + p2].
|
||||||
|
|
||||||
|
where offset1 and offset2 are dependent on the context mode.

/* Macros for compiler / platform specific features and build options.

|
Build options are:
|
||||||
|
* BROTLI_BUILD_32_BIT disables 64-bit optimizations
|
||||||
|
* BROTLI_BUILD_64_BIT forces to use 64-bit optimizations
|
||||||
|
* BROTLI_BUILD_BIG_ENDIAN forces to use big-endian optimizations
|
||||||
|
* BROTLI_BUILD_ENDIAN_NEUTRAL disables endian-aware optimizations
|
||||||
|
* BROTLI_BUILD_LITTLE_ENDIAN forces to use little-endian optimizations
|
||||||
|
* BROTLI_BUILD_MODERN_COMPILER forces to use modern compilers built-ins,
|
||||||
|
features and attributes
|
||||||
|
* BROTLI_BUILD_PORTABLE disables dangerous optimizations, like unaligned
|
||||||
|
read and overlapping memcpy; this reduces decompression speed by 5%
|
||||||
|
* BROTLI_DEBUG dumps file name and line number when decoder detects stream
|
||||||
|
or memory error
|
||||||
|
* BROTLI_ENABLE_LOG enables asserts and dumps various state information
