Now when tasklets are woken up via tasklet_wakeup(), tasklet_wakeup_on() or tasklet_wakeup_after(), either the optional wakeup flags will be used, or TASK_WOKEN_OTHER will be used. This allows tasklet handlers waking up for any given cause to notice whether or not they were also woken for another reason. For example, a mux handler could skip heavy parts when seeing that TASK_WOKEN_OTHER is absent, proving that no standard tasklet_wakeup() was done, for example in response to a subscribe(). The benefit of the TASK_WOKEN_* flags is that they're purged during the wakeup, and that they're easy to check for using TASK_WOKEN_ANY. TASK_F_UEVT1 and TASK_F_UEVT2 are also usable for private use (e.g. wakeup from a stream to a connection inside a mux). Probably that in the future, code dealing with subscribe events should start to place TASK_WOKEN_IO like is done for upper layers. |

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.
