Subject: SPDY: drop the "delayed" flag when finalizing connection.
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=7f54528ca07e49abd83d8c86c8125202dcf2798c;p=nginx.git

SPDY: drop the "delayed" flag when finalizing connection.

This flag in SPDY fake write events serves the same purposes as the "ready"
flag in real events, and it must be dropped if request needs to be handled.
Otherwise, it can prevent the request from finalization if ngx_http_writer()
was set, which results in a connection leak.
