They were initially made to deal with both the cache and the update list
but there's no cache anymore and keeping them for the update list adds a
lot of obfuscation that is really not desired. Let's get rid of them now.
Their purpose was simply to get a pointer to fdtab[fd].update.{,next,prev}
in order to perform atomic tests and modifications. The offset passed in
argument to the functions (fd_add_to_fd_list() and fd_rm_from_fd_list())
was the offset of the ->update field in fdtab, and as it's not used anymore
it was removed. This also removes a number of casts, though those used by
the atomic ops have to remain since only scalars are supported.
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)
