socket: avoid arg parsing in rsock_s_recvfrom_nonblock

2015-11-16T23:25:03+00:00

* ext/socket/init.c (rsock_s_recvfrom_nonblock):
  avoid arg parsing with C API
  [ruby-core:71439] [Feature #11339]
* ext/socket/basicsocket.c (bsock_recv_nonblock):
  adjust for above change, make private
* ext/socket/socket.c (sock_recvfrom_nonblock): ditto
* ext/socket/udpsocket.c (udp_recvfrom_nonblock): ditto
* ext/socket/lib/socket.rb (BasicSocket#recv_nonblock):
  new wrapper for private method, move RDoc
  (Socket#recvfrom_nonblock): ditto
  (UDPSocket#recvfrom_nonblock): ditto

Note, not adding bm_recv_nonblock.rb to benchmark/ directory
since it is non-portable.  It is only in this commit message.

socket: allow exception-free nonblocking sendmsg/recvmsg

2015-06-15T19:38:49+00:00

As documented before, exceptions are expensive and IO::Wait*able are too
common in socket applications to be the exceptional case.  Datagram
sockets deserve the same API which stream sockets are allowed with
read_nonblock and write_nonblock.

Note: this does not offer a performance advantage under optimal
conditions when both ends are equally matched in speed, but it it
does make debug output cleaner by avoiding exceptions whenever
the receiver slows down.

* ext/socket/ancdata.c (bsock_sendmsg_internal, bsock_recvmsg_internal):
  support "exception: false" kwarg
* ext/socket/init.c (rsock_s_recvfrom_nonblock):
  ditto
* ext/socket/init.c (rsock_s_recvfrom_nonblock): use rsock_opt_false_p
* ext/socket/socket.c (sock_connect_nonblock): ditto
* ext/socket/rubysocket.h (rsock_opt_false_p): new function
* ext/socket/basicsocket.c (bsock_recv_nonblock): update rdoc
* ext/socket/udpsocket.c (udp_recvfrom_nonblock): ditto
* test/socket/test_nonblock.rb: new tests
