The socket-specific accept() code in listener_accept() has nothing to do there. Let's move it to sock.c where it can be significantly cleaned up. It will now directly return an accepted connection and provide a status code instead of letting listener_accept() deal with various errno values. Note that this doesn't support the sockpair specific code. The function is now responsible for dealing with its own receiver's polling state and calling fd_cant_recv() when facing EAGAIN. One tiny change from the previous implementation is that the connection's sockaddr is now allocated before trying accept(), which saves a memcpy() of the resulting address for each accept at the expense of a cheap pool_alloc/pool_free on the final accept returning EAGAIN. This still apparently slightly improves accept performance in microbencharks.
The HAProxy documentation has been split into a number of different files for ease of use. 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)
