ruby--ruby/ruby.h
matz 2f8d3bdc21 * array.c (rb_ary_modify): should copy the internal buffer if the 
modifying buffer is shared.

* array.c (ary_make_shared): make an internal buffer of an array
  to be shared.

* array.c (rb_ary_shift): avoid sliding an internal buffer by
  using shared buffer.

* array.c (rb_ary_subseq): avoid copying the buffer.

* parse.y (gettable): should freeze __LINE__ string.

* io.c (rb_io_puts): old behavoir restored.  rationale: a) if you
  want to call to_s for arrays, you can just call print a, "\n".
  b) to_s wastes memory if array (and sum of its contents) is
  huge.  c) now any object that has to_ary is treated as an array,
  using rb_check_convert_type().

* hash.c (rb_hash_initialize): now accepts a block to calculate
  the default value. [new]

* hash.c (rb_hash_aref): call "default" method to get the value
  corrensponding to the non existing key.

* hash.c (rb_hash_default): get the default value based on the
  block given to 'new'.  Now it takes an optinal "key" argument.
  "default" became the method to get the value for non existing
  key.  Users may override "default" method to change the hash
  behavior.

* hash.c (rb_hash_set_default): clear the flag if a block is given
  to 'new'

* object.c (Init_Object): undef Data.allocate, left Data.new.

* ext/curses/curses.c (window_scrollok): use RTEST().

* ext/curses/curses.c (window_idlok): ditto.

* ext/curses/curses.c (window_keypad): ditto.

* ext/curses/curses.c (window_idlok): idlok() may return void on
  some platforms; so don't use return value.

* ext/curses/curses.c (window_scrollok): ditto for consistency.

* ext/curses/curses.c: replace FIX2INT() by typechecking NUM2INT().

* parse.y (str_extend): should not process immature #$x and
  #@x interpolation, e.g #@#@ etc.

* enum.c (enum_sort_by): sort_by does not have to be stable always.

* enum.c (enum_sort_by): call qsort directly to gain performance.

* util.c (ruby_qsort): ruby_qsort(qs6) is now native thread safe.

* error.c (rb_sys_fail): it must be a bug if it's called when
  errno == 0.

* regex.c (WC2MBC1ST): should not pass through > 0x80 number in UTF-8.
