This commit prepares read_cfg() to call load_cfg_in_mem() helper in order to load configuration files in memory. Before, read_cfg() calls the parser for all files from cfg_cfgfiles list and cumulates parser's errors and memprintf's errors in for_each loop. memprintf's errors did not stop this loop and were accounted just after. Now, as we plan to load configuration files in memory, we stop the loop, if memprintf() fails, and we show appropraite error message with ha_alert. Then process terminates. So not all cumulated syntax-related errors will be shown before exit in this case and we has to stop, because we run out of memory. If we can't open the current file or we fail to allocate a memory to store some configuration line, the previous behaviour is kept, process emits appropriate alert message and exits. If parser returns some syntax-related error on the current file, the previous behaviour is kept as well. We cumulate such errors for all parsed files and we check them just after the loop. All syntax-related errors for all files is shown then as before in ha_alert messages line by line during the startup. Then process will exit with 1. As now cfg_cfgfiles list contains many pointers to some memory areas with configuration files content and this content could be big, it's better to free the list explicitly, when parsing was finished. So, let's change read_cfg() to return some integer value to its caller init(), and let's perform the free routine at a caller level, as cfg_cfgfiles list was initialized and initially filled at this level.
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
