* add RUBY_TYPED_FREE_IMMEDIATELY to data types which only use

2013-10-29T11:16:54+00:00

  safe functions during garbage collection such as xfree().
  On default, T_DATA objects are freed at same points as fianlizers.
  This approach protects issues such as reported by [ruby-dev:35578].
  However, freeing T_DATA objects immediately helps heap usage.
  Most of T_DATA (in other words, most of dfree functions) are safe.
  However, we turned off RUBY_TYPED_FREE_IMMEDIATELY by default
  for safety.

io.c: make IO#reopen("pathname") atomic

2013-10-20T06:41:24+00:00

* io.c (rb_io_reopen): create a new, temporary FD via rb_sysopen and
  call rb_cloexec_dup2 on it to atomically replace the file fptr->fd
  points to.  This leaves no possible window where fptr->fd is invalid
  to userspace (even for any threads running w/o GVL).  based on the
  patch by Eric Wong  at [ruby-core:57943].
  [Bug #9036]

io.c: use rb_funcallv

2013-10-08T15:34:40+00:00

* io.c (rb_io_write): use rb_funcallv() instead of rb_funcall() to get
  rid of unnecessary alloca.

2013-10-06T18:43:50+00:00

* io.c (copy_stream_body): move src_io and dst_io back to top level
  and use instead of stp->src and stp->dst.

io.c: suppress false uninitialized-variable warning

2013-10-06T13:52:44+00:00

* io.c (io_ascii8bit_binmode): split from rb_io_ascii8bit_binmode() to
  call with rb_io_t* directly.

* io.c (copy_stream_body): move src_io and dst_io into each blocks
  where those are only used.

io.c: wait child process after close_read

2013-10-02T07:26:54+00:00

* io.c (rb_io_close_read): duplex IO should wait its child process
  even after close_read.

  to get rid of race condition.  [ruby-list:49598]

io.c: keep fptr read-closed

2013-10-02T05:19:00+00:00

* io.c (rb_io_close_read): keep fptr in write_io to be discarded, to
  fix freed pointer access when it is in use by other threads, and get
  rid of potential memory/fd leak.
