From c461bdc3c5243d4b0ea1f47b78fa67eac0d355db Mon Sep 17 00:00:00 2001 From: nagachika Date: Wed, 28 Mar 2018 13:54:58 +0000 Subject: merge revision(s) 60584,62954,62955,62956,62957,62958,62959,63008: webrick: support Proc objects as body responses * lib/webrick/httpresponse.rb (send_body): call send_body_proc (send_body_proc): new method (class ChunkedWrapper): new class * test/webrick/test_httpresponse.rb (test_send_body_proc): new test (test_send_body_proc_chunked): ditto [Feature #855] webrick/httpresponse: IO.copy_stream for regular files Remove the redundant _send_file method since its functionality is unnecessary with IO.copy_stream. IO.copy_stream also allows the use of sendfile under some OSes to speed up copies to non-TLS sockets. Testing with "curl >/dev/null" and "ruby -run -e httpd" to read a 1G file over Linux loopback reveals a reduction from around ~0.770 to ~0.490 seconds on the client side. * lib/webrick/httpresponse.rb (send_body_io): use IO.copy_stream (_send_file): remove [Feature #14237] webrick: use IO.copy_stream for single range response This is also compatible with range responses generated by Rack::File (tested with rack 2.0.3). * lib/webrick/httpresponse.rb (send_body_io): use Content-Range * lib/webrick/httpservlet/filehandler.rb (make_partial_content): use File object for the single range case * test/webrick/test_filehandler.rb (get_res_body): use send_body to test result test/webrick/test_filehandler.rb: stricter multipart range test We need to ensure we generate compatibile output in the face of future changes * test/webrick/test_filehandler.rb (test_make_partial_content): check response body webrick: quiet warning for multi-part ranges Content-Length is ignored by WEBrick::HTTPResponse even if we calculate it, so instead we chunk responses to HTTP/1.1 clients and terminate HTTP/1.0 connections. * lib/webrick/httpservlet/filehandler.rb (make_partial_content): quiet warning webrick/httpresponse: make ChunkedWrapper copy_stream-compatible The .write method needs to return the number of bytes written to avoid confusing IO.copy_stream. * lib/webrick/httpresponse.rb (ChunkedWrapper#write): return bytes written (ChunkedWrapper#<<): return self webrick: use IO.copy_stream for multipart response Use the new Proc response body feature to generate a multipart range response dynamically. We use a flat array to minimize object overhead as much as possible; as many ranges may fit into an HTTP request header. * lib/webrick/httpservlet/filehandler.rb (multipart_body): new method (make_partial_content): use multipart_body get rid of test error/failure on Windows introduced at r62955 * lib/webrick/httpresponse.rb (send_body_io): use seek if NotImplementedError is raised in IO.copy_stream with offset. * lib/webrick/httpservlet/filehandler.rb (multipart_body): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_2_4@63012 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- lib/webrick/httpresponse.rb | 68 ++++++++++++++++++++++++++++++++------------- 1 file changed, 49 insertions(+), 19 deletions(-) (limited to 'lib/webrick/httpresponse.rb') diff --git a/lib/webrick/httpresponse.rb b/lib/webrick/httpresponse.rb index 2551ead8ed..d1dd1ba141 100644 --- a/lib/webrick/httpresponse.rb +++ b/lib/webrick/httpresponse.rb @@ -310,6 +310,8 @@ module WEBrick def send_body(socket) # :nodoc: if @body.respond_to? :readpartial then send_body_io(socket) + elsif @body.respond_to?(:call) then + send_body_proc(socket) else send_body_string(socket) end @@ -424,9 +426,20 @@ module WEBrick end socket.write("0#{CRLF}#{CRLF}") else - size = @header['content-length'].to_i - _send_file(socket, @body, 0, size) - @sent_size = size + if %r{\Abytes (\d+)-(\d+)/\d+\z} =~ @header['content-range'] + offset = $1.to_i + size = $2.to_i - offset + 1 + else + offset = nil + size = @header['content-length'] + size = size.to_i if size + end + begin + @sent_size = IO.copy_stream(@body, socket, size, offset) + rescue NotImplementedError + @body.seek(offset, IO::SEEK_SET) + @sent_size = IO.copy_stream(@body, socket, size) + end end ensure @body.close @@ -455,24 +468,41 @@ module WEBrick end end - def _send_file(output, input, offset, size) - while offset > 0 - sz = @buffer_size < size ? @buffer_size : size - buf = input.read(sz) - offset -= buf.bytesize + def send_body_proc(socket) + if @request_method == "HEAD" + # do nothing + elsif chunked? + @body.call(ChunkedWrapper.new(socket, self)) + _write_data(socket, "0#{CRLF}#{CRLF}") + else + size = @header['content-length'].to_i + @body.call(socket) + @sent_size = size + end + end + + class ChunkedWrapper + def initialize(socket, resp) + @socket = socket + @resp = resp end - if size == 0 - while buf = input.read(@buffer_size) - output.write(buf) - end - else - while size > 0 - sz = @buffer_size < size ? @buffer_size : size - buf = input.read(sz) - output.write(buf) - size -= buf.bytesize - end + def write(buf) + return 0 if buf.empty? + socket = @socket + @resp.instance_eval { + size = buf.bytesize + data = "#{size.to_s(16)}#{CRLF}#{buf}#{CRLF}" + _write_data(socket, data) + data.clear + @sent_size += size + size + } + end + + def <<(*buf) + write(buf) + self end end -- cgit v1.2.3
