This is some prerequisite work for implementing PAT_REF events. In this commit we define the PAT_REF event_hdl family (which gets family slot id #2), with the following supported events: - EVENT_HDL_SUB_PAT_REF_ADD: element was added to the current version of the pattern ref - EVENT_HDL_SUB_PAT_REF_DEL: element was deleted from the current version of the pattern ref - EVENT_HDL_SUB_PAT_REF_SET: element was modified in the current version of the pattern ref - EVENT_HDL_SUB_PAT_REF_COMMIT: pending element(s) was/were commited in the current version of the pattern ref - EVENT_HDL_SUB_PAT_REF_CLEAR: all elements were cleared from the current version of the pattern ref The goal is to be able to track a pat_ref struct in order to be notified when it is updated. For performance reasons, events from this family won't provide any additional info, and will only be published in the pat_ref subscription list. Indeed, pat_ref may be updated at a relatively high frequency (or worse, batch work), so we cannot afford doing expensive treatment for each update. |

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.
