socket: allow explicit buffer for recv and recv_nonblock
This reduces GC overhead and makes the API more consistent with IO#read and IO#read_nonblock. * ext/socket/basicsocket.c (bsock_recv): document outbuf * ext/socket/unixsocket.c (unix_recvfrom): ditto * ext/socket/init.c (rsock_strbuf, recvfrom_locktmp): new functions (rsock_s_recvfrom): support destination buffer as 3rd arg (rsock_s_recvfrom_nonblock): ditto * string.c (rb_str_locktmp_ensure): export for internal ext * test/socket/test_nonblock.rb: test recv_nonblock * test/socket/test_unix.rb: test recv [ruby-core:69543] [Feature #11242] Benchmark results: user system total real alloc 0.130000 0.280000 0.410000 ( 0.420656) extbuf 0.100000 0.220000 0.320000 ( 0.318708) -------------------8<-------------------- require 'socket' require 'benchmark' nr = 100000 msg = ' ' * 16384 size = msg.bytesize buf = ' ' * size UNIXSocket.pair(:DGRAM) do |a, b| Benchmark.bmbm do |x| x.report('alloc') do nr.times do b.send(msg, 0) a.recv(size, 0) end end x.report('extbuf') do nr.times do b.send(msg, 0) a.recv(size, 0, buf) end end end end git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50912 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
