- [BUGFIX] Ensure that Largest Observed does not decrease in ACKs we send. ACK frames placed in packets in buffered queues (optimization introduced in 1.17.15) can be preceded by an ACK frame generated later. In this case, the older ACK frame should not be sent out, as Chromium- based servers flags decrease in the ACK frame's Largest Observed value as an error. |

LiteSpeed QUIC (LSQUIC) Client Library README
Description
LiteSpeed QUIC (LSQUIC) Client Library is an open-source implementation of QUIC functionality for clients. It is released in the hope to speed the adoption of QUIC. Most of the code in this distribution is used in our own products: LiteSpeed Web Server and ADC. We think it is free of major problems. Nevertheless, do not hesitate to report bugs back to us. Even better, send us fixes and improvements!
Currently supported QUIC versions are Q035, Q039, Q043, and Q044. Support for newer versions will be added soon after they are released. The version(s) specified by IETF QUIC WG are being developed on one or more branches. When deemed stable, the IETF QUIC support will be added to the master branch.
Documentation
The documentation for this module is admittedly sparse. The API is
documented in include/lsquic.h. If you have doxygen, you can run
doxygen dox.cfg
or make docs
. The example program is
test/http_client.c: a bare-bones, but working, QUIC client. Have a look
in EXAMPLES.txt to see how it can be used.
Requirements
To build LSQUIC, you need CMake, zlib, and BoringSSL. The example program uses libevent to provide the event loop.
Building BoringSSL
BoringSSL is not packaged; you have to build it yourself. The process is
straightforward. You will need go
installed.
- Clone BoringSSL by issuing the following command:
git clone https://boringssl.googlesource.com/boringssl
cd boringssl
- Check out stable branch:
git checkout chromium-stable
- Compile the library
cmake . && make
Remember where BoringSSL sources are:
BORINGSSL=$PWD
If you want to turn on optimizations, do
cmake -DCMAKE_BUILD_TYPE=Release . && make
Building LSQUIC Client Library
LSQUIC's http_client
and the tests link BoringSSL libraries statically.
Following previous section, you can build LSQUIC as follows:
- Get the source code
git clone https://github.com/litespeedtech/lsquic-client.git
cd lsquic-client
- Compile the library
# $BORINGSSL is the top-level BoringSSL directory from the previous step
cmake -DBORINGSSL_DIR=$BORINGSSL .
make
- Run tests
make test
Building with Docker
The library and http_client example can be built with Docker.
docker build -t lsquic-client .
Then you can use the http_client example from the command line.
docker run -it --rm lsquic-client http_client -H www.google.com -s 74.125.22.106:443 -p /
Platforms
The client library has been tested on the following platforms:
- Linux
- i386
- x86_64
- ARM (Raspberry Pi 3)
- FreeBSD
- i386
- Windows
- x86_64
- MacOS
- x86_64
Have fun,
LiteSpeed QUIC Team.
