This adds a sliding estimate of the pools' usage. The goal is to be able to use this to start to more aggressively free memory instead of keeping lots of unused objects in pools. The average is calculated as a sliding average over the last 1024 consecutive measures of ->used during calls to pool_free(), and is bumped up for 1/4 of its history from ->allocated when allocation from the pool fails and results in a call to malloc(). The result is a floating value between ->used and ->allocated, that tries to react fast to under-estimates that result in expensive malloc() but still maintains itself well in case of stable usage, and progressively goes down if usage shrinks over time. This new metric is reported as "needed_avg" in "show pools". Sadly due to yet another include dependency hell, we couldn't reuse the functions from freq_ctr.h so they were temporarily duplicated into memory.h. |

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)
