Process runtime information could be very useful in post_mortem, but we have to collect it just before calling run_poll_loop(). Like this we are sure, that we've successfully applied all configuration parameters and what we've collected are the latest runtime settings. The most appropraite place to collect such information is feed_post_mortem_late(). It's called in each thread, but puts thread info in the post_mortem only when it's in the last thread context. As it's called under mutex lock, other threads at this moment have to wait until feed_post_mortem_late() and another initialization functions from per_thread_init_list will finish. The number of threads could be large. So, to avoid spending a lot of time under the lock, let's exit immediately from feed_post_mortem_late(), if it wasn't called in the last thread.
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
