LiteSpeed QUIC (LSQUIC) Library README
LiteSpeed QUIC (LSQUIC) Library is an open-source implementation of QUIC and HTTP/3 functionality for servers and clients. Most of the code in this distribution is used in our own products: LiteSpeed Web Server, LiteSpeed ADC, and OpenLiteSpeed.
Currently supported QUIC versions are v1, Internet-Draft versions 29, and 27; and the older "Google" QUIC versions Q043, Q046, an Q050.
Documentation is available at https://lsquic.readthedocs.io/en/latest/.
In addition, see example programs for API usage and EXAMPLES.txt for some compilation and run-time options.
To build LSQUIC, you need CMake, zlib, and BoringSSL. The example program uses libevent to provide the event loop.
BoringSSL is not packaged; you have to build it yourself. The process is
straightforward. You will need
- Clone BoringSSL by issuing the following command:
git clone https://boringssl.googlesource.com/boringssl cd boringssl
You may need to install pre-requisites like zlib and libevent.
- Use specific BoringSSL version
git checkout a2278d4d2cabe73f6663e3299ea7808edfa306b9
- Compile the library
cmake . && make
Remember where BoringSSL sources are:
If you want to turn on optimizations, do
cmake -DCMAKE_BUILD_TYPE=Release . && make
If you want to build as a library, (necessary to build lsquic itself as as shared library) do:
cmake -DBUILD_SHARED_LIBS=1 . && make
Building LSQUIC Library
http_server, and the tests link BoringSSL
libraries statically. Following previous section, you can build LSQUIC
- Get the source code
git clone https://github.com/litespeedtech/lsquic.git cd lsquic git submodule init git submodule update
- Compile the library
# $BORINGSSL is the top-level BoringSSL directory from the previous step cmake -DBORINGSSL_DIR=$BORINGSSL . make
As a dynamic library:
cmake -DLSQUIC_SHARED_LIB=1 -DBORINGSSL_DIR=$BORINGSSL . make
- Run tests
Building with Docker
The library and the example client and server can be built with Docker.
Initialize Git submodules:
cd lsquic git submodule init git submodule update
Build the Docker image:
docker build -t lsquic .
Then you can use the examples from the command line. For example:
sudo docker run -it --rm lsquic http_client -s www.google.com -p / -o version=h3-29 sudo docker run -p 12345:12345/udp -v /path/to/certs:/mnt/certs -it --rm lsquic http_server -c www.example.com,/mnt/certs/chain,/mnt/certs/key
The library has been tested on the following platforms:
- ARM (Raspberry Pi 3)
Do not hesitate to report bugs back to us. Even better, send us fixes and improvements!
