A regression was introduced by 13a9232ebc63fdf357ffcf4fa7a1a5e77a1eac2b when I added support for Additional section of the SRV responses.. Basically, when a server is managed through SRV records additional section and it's disabled (because its associated Additional record has disappeared), it never leaves its MAINT state and so never comes back to production. This patch updates the "snr_update_srv_status()" function to clear the MAINT status when the server now has an IP address and also ensure this function is called when parsing Additional records (and associating them to new servers). This can cause severe outage for people using HAProxy + consul (or any other service registry) through DNS service discovery). This should fix issue #793. This should be backported to 2.2.
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)
