Subject: Upstream: clearing of u->peer.connection on close.
X-Git-Tag: release-1.1.5~18
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=28b001f897e3d3dfdffe1cca811657dd36961605;p=nginx.git

Upstream: clearing of u->peer.connection on close.

This fixes crashes observed with some 3rd party balancer modules.  Standard
balancer modules (round-robin and ip hash) explicitly set pc->connection
(aka u->peer.connection) to NULL and aren't affected.
