In issue #777, cppcheck wrongly assumes a useless null pointer check in the expression below while it's obvious that in a 3G/1G split on 32-bit, len can become positive if p is NULL: p = memchr(ctx.value.ptr, ' ', ctx.value.len); len = p - ctx.value.ptr; if (!p || len <= 0) return 0; In addition, on 64 bits you never know given that len is a 32-bit signed int thus the sign of the result in case of a null p will always be the opposite of the 32th bit of ctx.value.ptr. Admittedly the test is ugly. Tim proposed this fix consisting in checking for p == ctx.value.ptr instead when checking for first character only, which Ilya confirmed is enough to shut cppcheck up. No backport is needed. |

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)
