Willy Tarreau bfc7b7acd8 MAJOR: checks: add support for a new "drain" administrative mode ... This patch adds support for a new "drain" mode. So now we have 3 admin modes for a server : - READY - DRAIN - MAINT The drain mode disables load balancing but leaves the server up. It can coexist with maint, except that maint has precedence. It is also inherited from tracked servers, so just like maint, it's represented with 2 bits. New functions were designed to set/clear each flag and to propagate the changes to tracking servers when relevant, and to log the changes. Existing functions srv_set_adm_maint() and srv_set_adm_ready() were replaced to make use of the new functions. Currently the drain mode is not yet used, however the whole logic was tested with all combinations of set/clear of both flags in various orders to catch all corner cases.		2014-05-23 14:29:11 +02:00
