Merge "Make libbrotli vendor_ramdisk_available for snapuserd." am: 489ec4cb53 am: 08d1f3bb18 am: 6fe0692037 Original change: https://android-review.googlesource.com/c/platform/external/brotli/+/1500596 Change-Id: Ib9d4196cee3e418f90baa462456d5cfc7b5d2c7c
Please consider updating brotli to version 1.0.9 (latest).
Version 1.0.9 contains a fix to “integer overflow” problem. This happens when “one-shot” decoding API is used (or input chunk for streaming API is not limited), input size (chunk size) is larger than 2GiB, and input contains uncompressed blocks. After the overflow happens, memcpy
is invoked with a gigantic num
value, that will likely cause the crash.
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.

You can download and install brotli using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git cd vcpkg ./bootstrap-vcpkg.sh ./vcpkg integrate install vcpkg install brotli
The brotli port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
configure-cmake is an autotools-style configure script for CMake-based projects (not supported on Windows).
The basic commands to build, test and install brotli are:
$ mkdir out && cd out $ ../configure-cmake $ make $ make test $ make install
By default, debug binaries are built. To generate “release” Makefile
specify --disable-debug
option to configure-cmake
.
See Bazel
The basic commands to build and install brotli are:
$ mkdir out && cd out $ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=./installed .. $ cmake --build . --config Release --target install
You can use other CMake configuration.
See Premake5
To install the latest release of the Python module, run the following:
$ pip install brotli
To install the tip-of-the-tree version, run:
$ pip install --upgrade git+https://github.com/google/brotli
See the Python readme for more details on installing from source, development, and testing.
