rb_readwrite_syserr_fail

2015-12-23T14:58:47+00:00

* io.c (rb_readwrite_syserr_fail): works with the given errno than
  thread local errno.

prefer rb_syserr_fail

2015-12-23T08:57:48+00:00

* file.c, io.c, util.c: prefer rb_syserr_fail with saved errno
  over setting errno then call rb_sys_fail, not to be clobbered
  potentially and to reduce thread local errno accesses.

* ext/socket/ancdata.c: Check buffer full and ignore MSG_TRUNC flag.

2015-11-19T13:49:58+00:00

  buffer fullness is more robust to detect the message is too big for
  the buffer.
  AIX 7.1 recvmsg doesn't set MSG_TRUNC for rflags when MSG_PEEK is
  given.

* ext/socket/ancdata.c (bsock_recvmsg_internal): stretch the buffer size

2015-11-18T17:53:20+00:00

  only when vmaxdatlen is nil.

* ext/socket/ancdata.c (bsock_recvmsg_internal): stretch the buffer size

2015-11-18T01:37:34+00:00

  when EMSGSIZE occurs on non HAVE_STRUCT_MSGHDR_MSG_CONTROL platforms
  (such as, Windows).  fixes a test error revealed by r52625.

socket: fix typo for default size

2015-11-18T01:18:30+00:00

* ext/socket/ancdata.c (bsock_recvmsg_internal): use 4096 as
  default size to match pre-r52610, which also maps to a common
  page size.

Oops; absolutely no idea why I made this typo...
