In order for the code behind the "commit ssl cert" logic to be usable outside of the CLI context, some new "ckch_store_update_" functions are created. They allow to perform all the operations on ckch_stores to be performed without needing an appctx. The first function being called is ckch_store_update_init which mainly takes the ckch_store lock and checks that there is an ongoing transaction with the proper path (which was already done in cli_parse_commit_cert). The main one is ckch_store_update_process which replicates the logic that could be found in the cli_io_handler_commit_cert function. We iterate over the ckch instances of an existing ckch store and duplicate them in the new ckch store which is still detached from the tree, before replacing the old store with the new one. This whole operation could take some time so we were yielding every 10 instances or when applet_putstr calls would fail. The actual ckch_store operations and the applet related calls are now decorrelated in order to stop having to have an appctx during the ckch store/instances processing. The ckch_store_update_process will now update a "msg" buffer and a "state" that allow to send processing messages to the caller as well as keep the state of the processing "state machine". When the ckch_store_update_process loop is over, ckch_store_update_cleanup can be called to release the lock and free some now useless structures. |

HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
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
