resolvers_deinit() function is called on error, during post-parsing stage, or on deinit, when HAProxy is stopped. It releases all entities: resolvers, resolutions and SRV requests. There is no reason to defer the resolutions release by moving them in the death_row list because this function is terminal. And it is in fact a bug. Resolutions must not be released at the end of the function because resolvers were already freed. However some resolutions may still be attached to a reolver. Thus, when we try to remove it from the resolver's tree, in resolv_reset_resolution(), this resolver was already released. So now, resolution are immediately released. It means there is no more reason to track this function. calls to enter_resolver_code()/leave_resolver_code() have been removed. This patch should fix the issue #1680 and may be related to #1485. It must be backported as far as 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)
