In function hlua_hook, a yieldk is performed when function is yieldable. But the following code in that function seems to assume that the yield never returns, which is not the case! Moreover, Lua documentation says that in this situation the yieldk call must immediately be followed by a return. This patch adds a return statement after the yieldk call. It also adds some comments and removes a needless lua_sethook call. It could be backported to all stable versions, but it is not mandatory, because even if it is undefined behavior this bug doesn't seem to negatively affect lua 5.3/5.4 stacks.
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)
