'setenv', 'presetenv', 'unsetenv', 'resetenv' keywords in configuration could modify the process runtime environment. In case of master-worker mode this creates a problem, as the configuration is read only once before the forking a worker and then the master process does the reexec without reading any config files, just to free the memory. So, during the reload a new worker process will be created, but it will inherited the previous unchanged environment from the master in wait mode, thus it won't benefit the changes in configuration, related to '*env' keywords. This may cause unexpected behavior or some parser errors in master-worker mode. So, let's add a helper to backup all process env variables just before it will read its configuration. And let's also add helpers to clean up the current runtime environment and to restore it to its initial state (as it was before parsing the config). |

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
