+Upstream: fixed $upstream_response_time for filter_finalize + error_page.
+
+ngx_http_upstream_finalize_request() is always called twice when an
+output filter module calls ngx_http_filter_finalize_request() *and*
+a custom error page is configured by the error_page directive. This
+is because
+
+1. ngx_http_filter_finalize_request() triggers
+        calling ngx_http_terminate_request
+        => calling ngx_http_upstream_cleanup
+        => calling ngx_http_upstream_finalize_request
+
+2. ngx_http_internal_redirect() returns NGX_DONE
+        ==> ngx_http_special_response_handler() returns NGX_DONE
+        ==> ngx_http_filter_finalize_request() returns NGX_ERROR
+        ==> ngx_http_send_header() returns NGX_ERROR
+        ==> ngx_http_upstream_send_response() calls
+            ngx_http_upstream_finalize_request() again in the same
+            ngx_http_upstream_send_response() call as 1).
+
+This might result in corrupted $upstream_response_time values (close
+to the absolute timestamp value) when u->state->response_sec happens
+to be non-zero.
+
+This patch ensures that the $upstream_response_time value is only
+calculated upon the first ngx_http_upstream_finalize_request()
+invocation.

+The ngx_http_geoip_city_float_variable and
+ngx_http_geoip_city_int_variable functions did not always initialize
+all variable fields like "not_found", which could lead to empty values
+for those corresponding nginx variales randomly.

+description:
+Upstream: SSL handshake timeouts.
+
+Timeout may not be set on an upstream connection when we call
+ngx_ssl_handshake() in ngx_http_upstream_ssl_init_connection(),
+so make sure to arm it if it's not set.
+
+Based on a patch by Yichun Zhang.
