Subject: [PATCH 11/13] MEDIUM: config: only warn if stats are attached to
|
|
multi-process bind directives
|
|
|
|
Some users want to have a stats frontend with one line per process, but while
|
|
100% valid and safe, the config parser emits a warning. Relax this check to
|
|
ensure that the warning is only emitted if at least one of the listeners is
|
|
bound to multiple processes, or if the directive is placed in a backend called
|
|
from multiple processes (since in this case we don't know if it's safe).
|
|
(cherry picked from commit eb791e03b5c5abfddb24a439fa6434788db026b7)
