tasklet_wakeup_on() and its derivates (tasklet_wakeup_after() and tasklet_wakeup()) do not support passing a wakeup cause like task_wakeup(). This is essentially due to an API limitation cause by the fact that for a very long time the only reason for waking up was to process pending I/O. But with the growing complexity of mux tasks, it is becoming important to be able to skip certain heavy processing when not strictly needed. One possibility is to permit the caller of tasklet_wakeup() to pass flags like task_wakeup(). Instead of going with a complex naming scheme, let's simply make the flags optional and be zero when not specified. This means that tasklet_wakeup_on() now takes either 2 or 3 args, and that the third one is the optional flags to be passed to the callee. Eligible flags are essentially the non-persistent ones (TASK_F_UEVT* and TASK_WOKEN_*) which are cleared when the tasklet is executed. This way the handler will find them in its <state> argument and will be able to distinguish various causes for the call.
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
