Subject: Upstream keepalive: clearing of c->data in cached connections.
X-Git-Tag: release-1.17.7~13
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=953f53921505a884f3912f2d8db5217a71c0479a;p=nginx.git

Upstream keepalive: clearing of c->data in cached connections.

Previously, connections returned from keepalive cache had c->data
pointing to the keepalive cache item.  While this shouldn't be a problem
for correct code, as c->data is not expected to be used before it is set,
explicitly clearing it might help to avoid confusion.
