X-Git-Tag: 2.0.23~178
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6b114c5c37582ee85dcb3cf674a0a1736b6cc05b;p=thirdparty%2Fapache%2Fhttpd.git

Replace ap_send_fd invocation with bucket brigade calls.  Send an eos down
the chain and let the brigade close the file descriptor when the network
i/o is done.
