Subject: MEDIUM: config: authorize frontend and listen without bind.
X-Git-Tag: v1.5-dev13~236
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c6678e21bb88a65e9b05de2f7f4920db1a514ba8;p=thirdparty%2Fhaproxy.git

MEDIUM: config: authorize frontend and listen without bind.

This allows to easily add/remove "bind" entries to a frontend without
being forced to remove it when the last entry is temporarily removed.
While "disabled" may sometimes work in a frontend, it becomes trickier
on "listen" sections which can also hold servers and be referenced by
other frontends.

Note that a "listen" section with no "bind" is equivalent to a "backend"
section.

Configs without any listeners are still reported as invalid and refuse
to load.
