Each ca-file entry of the tree will now hold a list of the ckch instances that use it so that we can iterate over them when updating the ca-file via a cli command. Since the link between the SSL contexts and the CA file tree entries is only built during the ssl_sock_prepare_ctx function, which are called after all the ckch instances are created, we need to add a little post processing after each ssl_sock_prepare_ctx that builds the link between the corresponding ckch instance and CA file tree entries. In order to manage the ca-file and ca-verify-file options, any ckch instance can be linked to multiple CA file tree entries and any CA file entry can link multiple ckch instances. This is done thanks to a dedicated list of ckch_inst references stored in the CA file tree entries over which we can iterate (during an update for instance). We avoid having one of those instances go stale by keeping a list of references to those references in the instances. When deleting a ckch_inst, we can then remove all the ckch_inst_link instances that reference it, and when deleting a cafile_entry, we iterate over the list of ckch_inst reference and clear the corresponding entry in their own list of ckch_inst_link references.
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)
