We used to require fd_remove() to remove an FD from a poller when we still had the FD cache and it was not possible to directly act on the pollers. Nowadays we don't need this anymore as the pollers will automatically unregister disabled FDs. The fd_remove() hack is particularly problematic because it additionally hides the FD from the known FD list and could make one think it's closed. It's used at two places: - with the async SSL engine - with the listeners (when unbinding from an fd for another process) Let's just use fd_stop_both() instead, which will propagate down the stack to do the right thing, without removing the FD from the array of known ones. Now when dumping FDs using "show fd" on a process which still knows some of the other workers' FDs, the FD will properly be listed with a listener state equal to "ZOM" for "zombie". This guarantees that the FD is still known and will properly be passed using _getsocks().
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)
