When an abstract unix socket is bound by HAProxy (using "abns@" prefix), NUL bytes are appended at the end of its path until sun_path is filled (for a total of 108 characters). Here we add an alternative to pass only the non-NUL length of that path to connect/bind calls, such that the effective path of the socket's name is as humanly written. This may be useful to interconnect with existing softwares that implement abstract sockets with this logic instead of the default haproxy one. This is achieved by implementing the "abnsz" socket prefix (instead of "abns"), which stands for "zero-terminated ABNS". "abnsz" prefix may be used anywhere "abns" is. Internally, haproxy uses the custom socket family (AF_CUST_ABNS vs AF_CUST_ABNSZ) to differentiate default abns sockets from zero-terminated ones. Documentation was updated and regtest was added.

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.
