The ZOMBIE state on listener is a real mess. Listeners passing through this state have lost their consistency with the proxy AND with the fdtab. Plus this state is not used for all foreign listeners, only for those belonging to a proxy that entirely runs on another process, otherwise it stays in INIT state, which makes the usefulness extremely questionable. But the real issue is that it's impossible to untangle the receivers from the proxy state as long as we have this because of deinit()... So what we do here is to start by making unbind_listener() support being called more than once. This will permit to call it again to really close the FD and finish the operations if it's called with an FD that's in a fake state (such as INIT but with a valid fd).
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)
