Till now the local pool caches were implemented only when lockless pools were in use. This was mainly due to the difficulties to disentangle the code parts. However the locked pools would further benefit from the local cache, and having this would reduce the variants in the code. This patch does just this. It adds a new debug macro DEBUG_NO_LOCAL_POOLS to forcefully disable local pool caches, and makes sure that the high level functions are now strictly the same between locked and lockless (pool_alloc(), pool_alloc_dirty(), pool_free(), pool_get_first()). The pool index calculation was moved inside the CONFIG_HAP_LOCAL_POOLS guards. This allowed to move them out of the giant #ifdef and to significantly reduce the code duplication. A quick perf test shows that with locked pools the performance increases by roughly 10% on 8 threads and gets closer to the lockless one.
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)
