* configure.in: check function attirbute const and pure,

2016-05-08T17:44:51+00:00

  and define CONSTFUNC and PUREFUNC if available.
  Note that I don't add those options as default because
  it still shows many false-positive (it seems not to consider
  longjmp).

* vm_eval.c (stack_check): get rb_thread_t* as an argument
  to avoid duplicate call of GET_THREAD().

io.h: remove old macros

2016-01-11T00:01:12+00:00

* include/ruby/io.h (RB_IO_BUFFER_INIT, RB_IO_FPTR_NEW): remove
  old macros only for internal use and obsolete since 2.2.

socket: memoize common socket families in fptr->mode

2015-07-02T01:58:14+00:00

This provides a minor speedup by avoiding an extra syscall

	require 'socket'
	require 'benchmark'
	nr = 100000
	msg = 'hello world'
	buf = ''
	size = msg.bytesize
	puts(Benchmark.measure do
	  UNIXSocket.pair(:SEQPACKET) do |a, b|
	    nr.times do
	      a.sendmsg_nonblock(msg, 0, exception: false)
	      b.recv(size, 0, buf)
	    end
	  end
	end)

             user     system      total        real
before:  0.330000   0.340000   0.670000 (  0.678235)
 after:  0.290000   0.240000   0.530000 (  0.534527)

* ext/socket/rubysocket.h: flags for common socket families
  (rsock_getfamily): update signature
* include/ruby/io.h: comment socket FMODE flags
* ext/socket/init.c (rsock_getfamily): memoize family
* ext/socket/basicsocket.c: adjust rsock_getfamily calls
* ext/socket/ancdata.c: ditto

* include/ruby/io.h (FMODE_WSPLIT): Removed. The write() system call

2014-11-18T09:10:59+00:00

  is not required to split.  It was useful to avoid whole process
  blocking in Ruby 1.8 but not useful since write() is invoked without
  GVL.
  (FMODE_WSPLIT_INITIALIZED): Ditto.

* io.c (wsplit_p): Removed.
  (io_writable_length): Removed.
  (rb_fcntl): Don't update the removed flags.

io.c: move RFile initialization

2014-10-10T02:34:24+00:00

* io.c (rb_io_make_open_file): move from include/ruby/io.h, and
  hide too detailed implementations.

ruby/io.h: deprecate old macros

2014-10-10T02:27:41+00:00

* include/ruby/io.h (rb_io_mode_flags, rb_io_modenum_flags):
  deprecate old macros for compatibility for ruby 1.8 and older.

2014-07-24T07:03:38+00:00

  be used for platform-specific optimization. PACKED_STRUCT_UNALIGNED
  should be used. [ruby-core:63988] [Bug #10088]

rb_io_buffer_t: fix packing on gcc

2014-07-21T16:56:13+00:00

* include/ruby/io.h (rb_io_buffer_t): fix packing on gcc
  r46892 caused packing to be a no-op on gcc (4.7.2-5, Debian)

ruby/io.h: fix rb_io_buffer_t

2014-07-21T07:04:21+00:00

* include/ruby/io.h (rb_io_buffer_t): fix usage of PACKED_STRUCT().
  it must surround the whole declaration on VC.

rb_io_buffer_t: pack structure

2014-07-20T04:19:06+00:00

* include/ruby/io.h (rb_io_buffer_t): pack structure
  Reduces rb_io_t from 200 to 192 bytes, allowing rb_io_t to
  occupy one less cache line.
  [Feature #10050]

n.b. this leaves a 4-byte hole after the `cbuf' field which may
be used for future expansion.
