This new option, when set, will cause the callers of pool_alloc() and pool_free() to be recorded into an extra area in the pool that is expected to be helpful for later inspection (e.g. in core dumps). For example it may help figure that an object was released to a pool with some sub-fields not yet released or that a use-after-free happened after releasing it, with an immediate indication about the exact line of code that released it (possibly an error path). This only works with the per-thread cache, and even objects refilled from the shared pool directly into the thread-local cache will have a NULL there. That's not an issue since these objects have not yet been freed. It's worth noting that pool_alloc_nocache() continues not to set any caller pointer (e.g. when the cache is empty) because that would require a possibly undesirable API change. The extra cost is minimal (one pointer per object) and this completes well with DEBUG_POOL_INTEGRITY. |

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)
