freq-ctr struct is used by the shm_stats_file API, and more precisely, it is used in the shm_stats_file_object struct for counters. shm_stats_file_object struct requires to be plateform-independent, thus we switch to using explicit size types (AKA fixed width integer types) for freq-ctr, in the attempt to make freq-ctr size and memory mapping consistent from one platform to another. We cannot simply use fixed-width integer because some of them are involved in atomic operations, and forcing a given width could cause build issues on some platforms where atomic ops are not implemented for large integers. Instead we leverage the FIXED_SIZE macro to keep handling the integers as before, but forcing them to be stored using expected number of bytes (unused bytes will simply be ignored). No change of behavior should be expected.
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
- 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)
