The cmdline argument parsing was performed quite late, which prevents from retrieving elements that can be used to initialize the pools and certain sensitive areas. The goal is to improve this by parsing command line arguments right after the early init stage. This is possible because the cmdline parser already does very little beyond retrieving config elements that are used later. Doing so requires to move the parser code to a separate function and to externalize a few variables out of the function as they're used later in the boot process, in the original function. This patch creates init_args() but doesn't move it upfront yet, it's still executed just before init(), which essentially corresponds to what was done before (only the trash buffers, ACLs and Lua were initialized earlier and are not needed for this). The rest is not modified and as expected no change is observed. Note that the diff doesn't to justice to the change as it makes it look like the early init() code was moved to a new function after the function was renamed, while in fact it's clearly the parser itself which moved.
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)
