Thanks to the commit 5714aff4a6bf "DEBUG: pool: store the memprof bin on alloc() and update it on free()", the amount of memory allocations and memory "frees" is shown now on the same line, corresponded to the caller name. This is very convenient to debug memory leaks (haproxy should run with -dMcaller option). The implicit drawback of this solution is that we count twice same free_calls and same free_tot (bytes) values in cli_io_handler_show_profiling(), when we've calculed tot_free_calls and tot_free_bytes, by adding them to the these totalizators for p_alloc, malloc and calloc allocator types. See the details about why this happens in a such way in __pool_free() implementation and also in the commit message for 5714aff4a6bf. This double addition of free counters falses 'Delta_calls' and 'Delta_bytes', sometimes we even noticed that they show negative values. Same problem was with the calculation of average allocated buffer size for lines, where we show simultaneously the number of allocated and freed bytes.
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)
