Implements automatic selection of QMux MUX if "h3" ALPN has been negotiated on top of TCP/SSL. The first part of this change is to define "alpn" member of mux_proto_list. This is necessary so that conn_get_best_mux_entry() can select it when "h3" has been chosen. As a side-effect, this also automatically sets a default ALPN to "h3" for bind lines with "proto qmux". The most important change is to adapt the SSL layer. On handshake completion, the eligible MUX is retrieved via conn_select_mux_fe/be() functions. If xprt_qmux is required by it, MUX init is delayed and QMux handshake is started first. This last change is necessary as connection flags CO_FL_QMUX_RECV/SEND are only set if "proto qmux" is explicitely set. In case xprt_qmux is activated via pure ALPN negotiation, these flags are also set on xprt_qmux_init(). This is mandatory to ensure emission/reception of QMux transport parameters will be performed as expected. |

HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
Please refer to the following files depending on what you're looking for:
- INSTALL for instructions on how to build and install HAProxy
- BRANCHES to understand the project's life cycle and what version to use
- LICENSE for the project's license
- CONTRIBUTING for the process to follow to submit contributions
The more detailed documentation is located into the doc/ directory:
- doc/intro.txt for a quick introduction on HAProxy
- doc/configuration.txt for the configuration's reference manual
- doc/lua.txt for the Lua's reference manual
- doc/SPOE.txt for how to use the SPOE engine
- doc/network-namespaces.txt for how to use network namespaces under Linux
- doc/management.txt for the management guide
- doc/regression-testing.txt for how to use the regression testing suite
- doc/peers.txt for the peers protocol reference
- doc/coding-style.txt for how to adopt HAProxy's coding style
