In previous log backend implementation, we created a pseudo log target for each declared log server, and we made the log target's address point to the actual server address to save some time and prevent unecessary copies. But this was done without knowing that when FQDN is involved (more broadly when dns/resolution is involved), the "port" part of server addr should not be relied upon, and we should explicitly use ->svc_port for that purpose. With that in mind and thanks to the previous commit, some changes were required: we allocate a dedicated addr within the log target when target is in DGRAM mode. The addr is first initialized with known values and it is then updated automatically by _srv_set_inetaddr() during runtime. (the change is atomic so readers don't need to worry about it) addr from server "log target" (INET/DGRAM mode) is made of the combination of server's address (lacking the port part) and server's svc_port.
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)
