There are some delicate chicken-and-egg situations in the initialization code, because the init() function currently does way too much (it goes as far as parsing the config) and due to this it must be started very late. But it's also in charge of initializing a number of variables that are needed in early boot (e.g. hostname/pid for error reporting, or entropy for random generators). This patch carefully extracts all the early code that depends on absolutely nothing, and places it immediately after the STG_LOCK init stage. The only possible failures at this stage are only allocation errors and they continue to provoke an immediate exit(). Some environment variables, hostname, date, pid etc are retrieved at this stage. The program's arguments are also copied there since they're needed to be kept intact for the master process.
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)
