The various trace sources always have the same pattern:
- trace events
- trace source
- trace decoding function
Dropping these when USE_TRACE=0 definitely makes sense. There are two
modes of definition here:
- those designed after mux_h2 which interleave #define and the entry
definition in the event. These ones cannot be removed without a
significant code move to split the #define and usage apart. Instead
here we mark the struct __maybe_unused, so that the compiler will
just not implement it.
- those designed like stream.c where defines are separated. Here we
can simply enclose the events definition inside the USE_TRACE guard
For most of these the static declaration of the trace function was moved
after the events so that the #if defined(USE_TRACE) could be placed between
the two. Nothing else was changed.
This saves another 51 kB of object code when USE_TRACE=0.

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
- doc/internals for developer-specific documentation (not all up to date)
