Sun Apr 10 17:47:42 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	* file.c (rb_realpath_internal): no argument conversions since
	  this internal function does not need to_path and encoding

	  RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO 0.3 -> 0.2
	  RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO 0.8 -> 0.65

	  These values are same as Ruby 2.0.0.

	  This change cause GC counts.
	  However, generational GC reduced each (minor) GC time and
	  increase memory locality. So that not so big impact on my
	  benchmarking results.
	  (surprisingly, this fix speed up programs on some cases)

	  You can change these values by environment variables
	  if you feel wrong.

Mon Apr  4 17:36:52 2016  Koichi Sasada  <ko1@atdot.net>

	* gc.c (get_envparam_double): take an upper_bound.

	  And also take an accept_zero flag which allow to accept zero
	  even if lower_bound is set.

	* gc.c (ruby_gc_set_params): fix parameters.

	  RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO set 0.9 as *lower_bound*, so that
	  it should be upper_bound.
	  Set RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO as lower bound.

	  Also set lower/upper bound of RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO to
	  RUBY_GC_HEAP_FREE_SLOTS_MIN/MAX_RATIO.

Mon Apr  4 16:41:32 2016  Koichi Sasada  <ko1@atdot.net>

	* vm.c (Init_VM): should pass tokens.

Sun Apr  3 09:34:29 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	  and module is required.

	* numeric.c (dbl2ival): do not round here.

	* numeric.c (flo_ceil): use dbl2ival.

	* numeric.c (flo_round): round explicitly.

Sat Apr  2 15:24:18 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

Fri Apr  1 20:58:33 2016  Martin Duerst  <duerst@it.aoyama.ac.jp>

	* enc/unicode/case-folding.rb, casefold.h: Data generation to implement
	  swapcase functionality for titlecase characters. Swapcase isn't defined
	  by Unicode, because the purpose/usage of swapcase is unclear anyway.
	  The implementation follows a proposal from Nobu, swapping the case of
	  each component of a titlecase character individually.
	  This means that the titlecase characters have to be decomposed.

	* enc/unicode.c: Code using the above data.

	* test/ruby/enc/test_case_mapping.rb: Tests for the above.

Fri Apr  1 14:55:28 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* configure.in (AC_CONFIG_FILES): $srcdir/.git can be a file pointing
	  the real git_dir, such as when the git working tree is a "linked
	  working tree" (a working tree created by git-worktree). So use
	  git-rev-parse --git-dir to check if $srcdir is the top-level of a git
	  repository, not just checking if the $srcdir/.git directory does exist
	  or not.  [ruby-core:74759] [Bug #12239]

	* tool/change_maker.rb: use tool/vcs.rb to detect VCS. This used to have
	  its own VCS detection code, while we have tool/vcs.rb.

	* tool/vcs.rb (detect): remove code duplication

Fri Apr  1 04:50:44 2016  Eric Wong  <e@80x24.org>

	* ext/openssl/ossl_ssl.c (ossl_sslctx_s_alloc):

Thu Mar 31 19:16:16 2016  Koichi Sasada  <ko1@atdot.net>

	* gc.c: need to set initial value of GC_HEAP_FREE_SLOTS_GOAL_RATIO.

Thu Mar 31 17:50:27 2016  Koichi Sasada  <ko1@atdot.net>

	* gc.c: change additional allocation policy.

	  Introduce new environment variable
	  RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO (goal_ratio) to calculate the
	  ratio of additional memory.

	  Before this change, we add pages with the following formula
	  (when free_slots < total_pages * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO):
	    next_pages = total_pages * RUBY_GC_HEAP_GROWTH_FACTOR

	  This addition can allocate too much.

	  With this change, we increase pages to satisfy the following formula:
	    next_free_slots = next_total_slots * goal_ratio
	  where
	    next_free_slots = free_slots + adding_slots
	    next_total_slots = total_slots + adding_slots.

	  If you want to prepare many free slots, increase this ratio.

	  If this variable is 0, then simply multiply
	  RUBY_GC_HEAP_GROWTH_FACTOR.

	* gc.c (get_envparam_double): enable to accept 0.

Thu Mar 31 17:48:25 2016  Koichi Sasada  <ko1@atdot.net>

	* gc.c (gc_marks_finish): fix syntax error.

Thu Mar 31 16:49:36 2016  Koichi Sasada  <ko1@atdot.net>

	* gc.c: simplify allocate/free detecting logic at the end of marking.

	  Before this change, heap_pages_min_slots are calculated at the
	  beginning sweeping phase. And this value is used at the end of
	  *next* marking phase.

	  To simplify it, we use this value at the end of this marking phase.
	  It means that we don't need to store this value as global state.

	  Also heap_pages_max_slots is calculated at the begging of sweeping
	  phase and used at the end of sweeping phase.
	  To simplify this logic, we introduced new global value
	  heap_pages_freeable_pages it means extra pages count we can free.
	  gc_sweep_step() checks this value and moves empty pages to tomb_heap
	  not more than this value.

	  Because of this fix, heap_pages_swept_slots is no longer needed.

	* gc.c (rb_objspace_t::heap_pages): restruct the objspace global
	  status.

	  remove the following fields
	    * swept_slots (and heap_pages_swept_slots)
	    * min_free_slots (and heap_pages_min_free_slots)
	    * max_free_slots (and heap_pages_max_free_slots)
	  And add the following filed.
	    * freeable_pages (and heap_pages_freeable_pages)

	* gc.c (heap_pages_free_unused_pages): unlink tomb heap pages
	  because tomb heap should have only freeable pages.

	* gc.c (heap_extend_pages): add parameters for future extension.

Thu Mar 31 16:43:02 2016  Koichi Sasada  <ko1@atdot.net>

	* gc.c: add GC parameters to configure the following values:
	  * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO:
	    allocate additional pages when free slots is lower than
	    the value (total_slots * (this ratio)).
	  * RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO:
	    allow to free pages when free slots is greater than
	    the value (total_slots * (this ratio)).

	  Before this change, these values are hard coded.

	* gc.c (ruby_gc_params_t): ditto.

	* gc.c (ruby_gc_set_params): ditto.

	* test/rinda/test_rinda.rb (test_make_socket_ipv4_multicast):

Fri Mar  4 19:19:42 2016  Koichi Sasada  <ko1@atdot.net>

	* gc.c: use 2 bits with unsigned int for rb_objspace::flags::mode
	  because it always returns 0 to 2 (non-negative value).

Fri Mar  4 18:42:08 2016  Koichi Sasada  <ko1@atdot.net>

	* gc.c: rename "enum gc_stat" to "enum gc_mode"
	  because there is a same name (no related) function gc_stat().

	  Also gc_stat_* are renamed to gc_mode_*,
	  gc_stat_transition() to gc_mode_transition(),
	  rb_objspace::flags::stat is renamed to rb_objspace::flags::mode.

	  Change rb_objspace::flags::mode from 2 bits to 3 bits because VC++
	  returns negative enum value with 2 bits.

	* gc.c (gc_mode): add a macro to access rb_objspace::flags::mode
	  with verification code (verification is enabled only on
	  RGENGC_CHECK_MODE > 0).

	* lib/forwardable.rb: Convert given accessors to String.

	  r53381 changed to accept only Symbol or String for accessors, but
	  there are several rubygems that pass classes (e.g. Array,
	  Hash, ...) as accessors. Prior r53381, it was accepted because Class#to_s
	  returns its class name. After r53381 given accessors are checked
	  with define_method, but it accepts only Symbol or String, otherwise
	  raises TypeError.

	      def_delegator Foo, :some_method

	  This change is to revert unexpected incompatibility. But this behavior
	  may change in the future.
