BROKEN: the failure rate on reg-tests/seamless-reload/abns_socket.vtc has significantly increased for no obvious reason. It fails 99% of the time vs 10% before. do_unbind_listener() is not logical and is not even idempotent. It must not touch the fd if already -1, which also means not touch the receiver. In addition, when performing a partial stop on a socket (not closing), we know the socket remains in the listening state yet it's marked as LI_ASSIGNED, which is confusing as it doesn't translate its real state. With this change, we make sure that FDs marked for close end up in ASSIGNED state and that those which are really bound and on which a listen() was made (i.e. not pause) remain in LISTEN state. This is what is closest to reality. Ideally this function should become a default proto->unbind() one but it may still keep a bit too much state logic to become generalized to other protocols (e.g. QUIC).
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)
