Subject: Upstream: updated list of ngx_event_connect_peer() return values.
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=523191ec89a11f3ffc81f6b6b710f46f86fa33d0;p=nginx.git

Upstream: updated list of ngx_event_connect_peer() return values.

ngx_http_upstream_get_keepalive_peer() may return NGX_DONE to
indicate that the cached keepalive connection is reused.
