If a pattern list is empty, there's no way we can find its elements in the pattern cache, so let's avoid this expensive lookup. This can happen for ACLs or maps loaded from files that may optionally be empty for example. Doing so improves the request rate by roughly 10% for a single such match for only 8 threads. That's normal because the LRU cache pre-creates an entry that is about to be committed for the case the list lookup succeeds after a miss, so we bypass all this.
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)
