	  bound to the outer method.  [ruby-core:72482] [Bug #11873]

	* parse.y (parse_ident): revert r56198.

	* parse.y (warn_balanced): the state of symbol and numeric
	  literals is now EXPR_ENDARG, do not exclude it.

Tue Sep 27 22:59:42 2016  URABE Shyouhei  <shyouhei@ruby-lang.org>

	* NEWS: news about Warning.warn.

Tue Sep 27 18:10:18 2016  Jeremy Evans <code@jeremyevans.net>

	* error.c: This makes all warnings raised call Warning.warn, which
	  by default does the same thing it does currently
	  (rb_write_error_str).  You can override Warning.warn to change
	  the behavior. [ruby-core:75016] [Feature #12299]

Tue Sep 27 17:35:28 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	  punctuation.

Mon Sep 26 16:23:49 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* ext/stringio/stringio.c (strio_seek): Avoid signed integer overflow.
	  It's not harmful in practice here, but is still undefined behavior.

	* ext/stringio/stringio.c (strio_extend): Check that the new length does
	  not exceed LONG_MAX. This fixes the invalid write on the overflow.

	* test/stringio/test_stringio.rb (test_write_integer_overflow): Add a
	  test case for the above fix in strio_extend().

Mon Sep 26 15:43:34 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* eval_intern.h (TH_PUSH_TAG): Initialize struct rb_vm_tag::tag with
	  Qundef rather than 0 which is equal to Qfalse. Since Kernel#throw(obj)
	  searches a tag with rb_vm_tag::tag == obj, throw(false) can
	  accidentally find an unrelated tag which is not created by
	  Kernel#catch.  [ruby-core:77229] [Bug #12743]

	* test/ruby/test_exception.rb (test_throw_false): Add a test case for
	  this.

Mon Sep 26 14:36:12 2016  Naotoshi Seo  <sonots@gmail.com>

	* lib/tempfile.rb: provide default basename parameter for
	  Tempfile.create. [Feature #11965] Patch by Yuki Kurihara

	  byte optimizable strings, as well as rstrip_offset.

Mon Sep 26 12:00:12 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	* gems/bundled_gems: update to minitest-5.9.1.

Mon Sep 26 11:50:03 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* tool/rbinstall.rb (gem): Don't install gemspec if no files will be
	  installed for the gem. This happens when the extension library is not
	  compiled.

Mon Sep 26 11:06:47 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* string.c (enc_strlen, rb_enc_strlen_cr): Avoid signed integer
	  overflow. The result type of a pointer subtraction may have the same
	  size as long. This fixes String#size returning an negative value on
	  i686-linux environment:

	    str = "\x00" * ((1<<31)-2))
	    str.slice!(-3, 3)
	    str.force_encoding("UTF-32BE")
	    str << 1234
	    p str.size

Sun Sep 25 22:48:06 2016  namusyaka  <namusyaka@gmail.com>

	* lib/erb.rb (ERB::Compiler::TrimScanner#stag): The :stag accessor
	  has already been available because it is defined in parent
	  Scanner class.  [Fix GH-1445]

Sun Sep 25 19:21:26 2016  Kazuki Tsujimoto  <kazuki@callcc.net>

	* node.c (dump_array): remove duplicate header of NODE_ARRAY/
	  NODE_VALUES.

Sat Sep 24 22:26:20 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	  extra libraries to be installed.

	* tool/rbinstall.rb (ext-arch): install extra libraries.

	* ext/zlib/extconf.rb: install zlib if built.

Sat Sep 24 11:28:22 2016  Koichi ITO  <koic.ito@gmail.com>

	* fix typos, "a" before "Integer" to "an".  [Fix GH-1438]

Sat Sep 24 10:19:41 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	* test/misc/test_ruby_mode.rb (assert_indent): since write-region
	  in Emacs 25.1 no longer displays the "Wrote file" message, shows
	  the explicit message to check if successfully finished.
	  [ruby-core:77355] [Bug #12785]

	* test/misc/test_ruby_mode.rb (EXPR_SAVE): use a numeric prefix
	  argument of 0, not to make the previous version into a backup
	  file, instead of backup-inhibited.

	* test/misc/test_ruby_mode.rb (run_emacs): always save the buffer
	  if modified.

Fri Sep 23 23:57:40 2016  Shugo Maeda  <shugo@ruby-lang.org>

	* vm_method.c (make_method_entry_refined): fix wrong use of ||.

Fri Sep 23 21:38:58 2016  Akinori MUSHA  <knu@iDaemons.org>

	  `Lk` macro.

	* tool/mdoc2man.rb (Mdoc2Man#shift_arg): A new function to extract
	  a possibly quoted argument.

Fri Sep 23 20:36:05 2016  Shugo Maeda  <shugo@ruby-lang.org>

	* eval.c (rb_mod_refine): refine modules as well.
	  [ruby-core:76199] [Feature #12534]

Fri Sep 23 20:19:09 2016  Akinori MUSHA  <knu@iDaemons.org>

	* man/ruby.1: Update the paragraphs in "Rich Libraries" which
	  included a dead link.

Fri Sep 23 20:05:27 2016  Akinori MUSHA  <knu@iDaemons.org>

	* man/ruby.1, man/erb.1, man/irb.1, man/ri.1: Use the `Lk` macro
	  for hyperlinks, which has been available since mdocml 1.5.1
	  (released more than seven years ago).

Fri Sep 23 15:47:04 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	* lib/forwardable.rb (_delegator_method): allow private methods to
	  be delegated, with warnings.  [ruby-core:77341] [Bug #12782]

Fri Sep 23 12:15:29 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	* compile.c (iseq_peephole_optimize): enable tail call
	  optimization inside a conditional block.

Thu Sep 22 13:00:04 2016  Kazuhiro NISHIYAMA  <zn@mbf.nifty.com>

	* gc.c (gc_start_internal): [DOC] methods without arguments
	  like r56194. [Bug #12777]

Wed Sep 21 17:43:53 2016  NARUSE, Yui  <naruse@ruby-lang.org>

	* process.c (InitVM_process): Support CLOCK_MONOTONIC_RAW_APPROX,
	  CLOCK_UPTIME_RAW, and CLOCK_UPTIME_RAW_APPROX which are introduced
	  by macOS 10.12.

Wed Sep 21 13:47:33 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	* parse.y (brace_body, do_body): preserve cmdarg_stack so that
	  `do` after cmdarg in a block should be `do_block` and bound to
	  the outer method.  [ruby-core:72482] [Bug #11873]

	* parse.y: `do` after cmdarg in parentheses should be `do_block`
	  and bound to the outer method.  [ruby-core:72482] [Bug #11873]

Sat Sep 17 02:40:52 2016  Aaron Patterson <tenderlove@ruby-lang.org>

	  dumps. Full heap dumps should use JSON lines (http://jsonlines.org)

Fri Sep 16 22:10:31 2016  Naohisa Goto  <ngotogenome@gmail.com>

	* ext/openssl/ossl_ssl.c (ssl_npn_select_cb_common): Fix compile error

	  [Bug #12769] [ruby-dev:49809]

Fri Sep 16 21:28:25 2016  Naohisa Goto  <ngotogenome@gmail.com>

	* internal.h (MAYBE_UNUSED): The fallback definition is needed.
	  Fix compile error with some non-GCC compilers such as
	  Oracle Solaris Studio 12.3 on Solaris 10.
	  [Bug #12767] [ruby-dev:49807]

	* internal.h (WARN_UNUSED_RESULT): ditto.

Fri Sep 16 21:19:51 2016  Naohisa Goto  <ngotogenome@gmail.com>

	* hash.c (each_pair_i_fast): Fix compile error with old version of
	  fcc on Solaris 10. [Bug #12768] [ruby-dev:49808]

Fri Sep 16 19:46:05 2016  NAKAMURA Usaku  <usa@ruby-lang.org>

	* win32/Makefile.sub (config.h): fixed compile error with VC introduced
	  by previous commit.

Fri Sep 16 14:54:34 2016  URABE Shyouhei  <shyouhei@ruby-lang.org>

	* internal.h (WARN_UNUSED_RESULT): moved to configure.in, to
	  actually check its availability rather to check GCC's version.

	* configure.in (WARN_UNUSED_RESULT): moved to here.

	* configure.in (RUBY_FUNC_ATTRIBUTE): change function declaration
	  to return int rather than void, because it makes no sense for a
	  warn_unused_result attributed function to return void.

	  Funny thing however is that it also makes no sense for noreturn
	  attributed function to return int.  So there is a fundamental
	  conflict between them.  While I tested this, I confirmed both
	  GCC 6 and Clang 3.8 prefers int over void to correctly detect
	  necessary attributes under this setup.  Maybe subject to change
	  in future.

	* internal.h (UNINITIALIZED_VAR): renamed to MAYBE_UNUSED, then
	  moved to configure.in for the same reason we move
	  WARN_UNUSED_RESULT.

	* configure.in (MAYBE_UNUSED): moved to here.

	* internal.h (__has_attribute): deleted, because it has no use now.

	* string.c (rb_str_enumerate_lines): refactor macro rename.

	* string.c (rb_str_enumerate_bytes): ditto.

	* string.c (rb_str_enumerate_chars): ditto.

	* string.c (rb_str_enumerate_codepoints): ditto.

	* thread.c (do_select): ditto.

	* vm_backtrace.c (rb_debug_inspector_open): ditto.

	* vsnprintf.c (BSD_vfprintf): ditto.

Fri Sep 16 14:35:55 2016  URABE Shyouhei  <shyouhei@ruby-lang.org>

	* ChangeLog (add-log-time-format): Not exactly sure when but
	  recently (25.x maybe), emacs changed its API to take optional
	  two arguments.  We have to follow that.

Fri Sep 16 06:43:25 2016  Aaron Patterson <tenderlove@ruby-lang.org>

	* lib/uri/generic.rb (def check_password): don't include bad password
	  in URI exception output

	* test/uri/test_generic.rb (def test_set_component): test for behavior

	  str_shared_replace, rb_str_init, str_make_independent_expand,
	  rb_str_resize): Avoid overflow by casting the length to size_t. size_t
	  should be able to represent LONG_MAX+termlen.

	* string.c (rb_str_modify_expand): Check that the new length is in the
	  range of long before resizing. Also refactor to use RESIZE_CAPA_TERM
	  macro.

	* string.c (str_buf_cat): Fix so that it does not create a negative
	  length String. Also fix the condition for 'string sizes too big', the
	  total length can be up to LONG_MAX.

	* string.c (rb_str_plus): Check the resulting String length does not
	  exceed LONG_MAX.

	* string.c (rb_str_dump): Fix integer overflow. The dump result will be
	  longer then the original String.

Tue Sep 13 21:30:53 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* gc.c (heap_extend_pages, get_envparam_size, ruby_malloc_size_overflow,
	  gc_profile_dump_on): Use PRIuSIZE instead of PRIdSIZE as the passed
	  value is size_t, not ssize_t.

	* iseq.c (get_line_info, rb_iseq_disasm_insn): Ditto.

	* sprintf.c (rb_str_format): Ditto.

	* thread_win32.c (native_thread_create): Ditto.

	  it in more places.

Tue Sep 13 21:23:51 2016  Kazuhiro NISHIYAMA  <zn@mbf.nifty.com>

	* README.md: Drop support for BeOS now that Haiku is stable since
	  2.3.0.

	* README.ja.md: ditto.

	* test/ruby/test_gc.rb: add a test.

Wed Jul 13 15:59:59 2016  NAKAMURA Usaku  <usa@ruby-lang.org>

	* math.c (_USE_MATH_DEFINES): it must be set before including internal.h
	  because internal.h includes ruby.h, ruby.h includes win32.h, and
	  win32.h includes system's math.h.
	  this change is to get rid of a compiler warning (redefinition of

	* string.c (rb_str_change_terminator_length): New function to change
	  termlen and resize heap for the terminator. This is split from
	  rb_str_fill_terminator (str_fill_term) because filling terminator
	  and changing terminator length are different things. [Bug #12536]

	* internal.h: declaration for rb_str_change_terminator_length.

	* string.c (str_fill_term): Simplify only to zero-fill the terminator.
	  For non-shared strings, it assumes that (capa + termlen) bytes of
	  heap is allocated. This partially reverts r55557.

	* encoding.c (rb_enc_associate_index): rb_str_change_terminator_length
	  is used, and it should be called whenever the termlen is changed.

	* string.c (str_capacity): New static function to return capacity
	  of a string with the given termlen, because the termlen may
	  sometimes be different from TERM_LEN(str) especially during
	  changing termlen or filling terminator with specific termlen.

	* string.c (rb_str_capacity): Use str_capacity.

	* insns.def (opt_plus): use `- 1` instead of `& (~1)` to allow
	  compilers to use x86 LEA instruction (3 operand).
	  Even if 3 operand LEA's latency is 3 cycle after SandyBridge,
	  it reduces code size and can be faster because of super scalar.

	* insns.def (opt_plus): calculate and use rb_int2big.
	  On positive Fixnum overflow, `recv - 1 + obj` doesn't carry
	  because recv's msb and obj's msb are 0, and resulted msb is 1.
	  Therefore simply rshift and cast as signed long works fine.
	  On negative Fixnum overflow, it will carry because both arguments'
	  msb are 1, and resulted msb is also 1.
	  In this case it needs to restore carried sign bit after rshift.

Sun Jun 19 21:25:43 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* ext/openssl/ossl_ocsp.c: Add OCSP::SingleResponse that represents an
	  OCSP SingleResponse structure. Also add two new methods #responses
	  and #find_response to OCSP::BasicResponse. A BasicResponse has one or
	  more SingleResponse. We have OCSP::BasicResponse#status that returns
	  them as an array of arrays, each containing the content of a
	  SingleResponse, but this is not useful. When validating an OCSP
	  response, we need to look into the each SingleResponse and check their
	  validity but it is not simple. For example, when validating for a
	  certificate 'cert', the code would be like:

	    # certid_target is an OpenSSL::OCSP::CertificateId for cert
	    basic = res.basic
	    result = basic.status.any? do |ary|
	      ary[0].cmp(certid_target) &&
	        ary[4] <= Time.now && (!ary[5] || Time.now <= ary[5])
	    end

	  Adding OCSP::SingleResponse at the same time allows exposing
	  OCSP_check_validity(). With this, the code above can be rewritten as:

	    basic = res.basic
	    single = basic.find_response(certid_target)
	    result = single.check_validity

	* test/openssl/test_ocsp.rb: Test this.

Sun Jun 19 18:40:19 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* ext/openssl/ossl_ocsp.c (ossl_ocspbres_add_status): Allow specifying
	  the times (thisUpdate, nextUpdate and revocationTime) with Time
	  objects. Currently they accepts only relative seconds from the current
	  time. This is inconvenience, especially for revocationTime. When
	  Integer is passed, they are still treated as relative times. Since the
	  type check is currently done with rb_Integer(), this is a slightly
	  incompatible change. Hope no one passes a relative time as String or
	  Time object...
	  Also, allow passing nil as nextUpdate. It is optional.

	* ext/openssl/ruby_missing.h: Define RB_INTEGER_TYPE_P() if not defined.
	  openssl gem will be released before Ruby 2.4.0.

	* ext/openssl/ossl_ssl.c (ossl_sslctx_s_alloc): Enable the automatic
	  curve selection for ECDH by calling SSL_CTX_set_ecdh_auto(). With
	  this a TLS server automatically selects a curve which both the client
	  and the server support to use in ECDH. This changes the default
	  behavior but users can still disable ECDH by excluding 'ECDH' cipher
	  suites from the cipher list (with SSLContext#ciphers=). This commit
	  also deprecate #tmp_ecdh_callback=. It was added in Ruby 2.3.0. It
	  wraps SSL_CTX_set_tmp_ecdh_callback() which will be removed in OpenSSL
	  1.1.0. Its callback receives two values 'is_export' and 'keylength'
	  but both are completely useless for determining a curve to use in
	  ECDH. The automatic curve selection was introduced to replace this.

	  (ossl_sslctx_setup): Deprecate SSLContext#tmp_ecdh_callback=. Emit a
	  warning if this is in use.

	  (ossl_sslctx_set_ecdh_curves): Add SSLContext#ecdh_curves=. Wrap
	  SSL_CTX_set1_curves_list(). If it is not available, this falls back

	  for data file availability; refactoring.

Sat May 28 14:00:10 2016  Kazuki Yamaguchi  <k@rhe.jp>

	* ext/openssl/lib/openssl/ssl.rb (SSLSocket): Move the implementation of
	  SSLSocket#initialize to C. Initialize the SSL (OpenSSL object) in it.
	  Currently this is delayed until ossl_ssl_setup(), which is called from
	  SSLSocket#accept or #connect. Say we call SSLSocket#hostname= with an
	  illegal value. We expect an exception to be raised in #hostname= but
	  actually we get it in the later SSLSocket#connect. Because the SSL is
	  not ready at #hostname=, the actual call of SSL_set_tlsext_host_name()
	  is also delayed.
	  This also fixes: [ruby-dev:49376] [Bug #11724]

	* ext/openssl/ossl_ssl.c (ossl_ssl_initialize): Added. Almost the same
	  as the Ruby version but this instantiate the SSL object at the same
	  time.

	  (ossl_ssl_setup): Adjust to the changes. Just set the underlying IO to
	  the SSL.

	  (ssl_started): Added. Make use of SSL_get_fd(). This returns -1 if not
	  yet set by SSL_set_fd().

	  (ossl_ssl_data_get_struct): Removed. Now GetSSL() checks that the SSL
	  exists.

	  (ossl_ssl_set_session): Don't call ossl_ssl_setup() here as now the
	  SSL is already instantiated in #initialize.

	  (ossl_ssl_shutdown, ossl_start_ssl, ossl_ssl_read_internal,
	   ossl_ssl_write_internal, ossl_ssl_stop, ossl_ssl_get_cert,

	   ossl_ssl_get_verify_result, ossl_ssl_get_client_ca_list,
	   ossl_ssl_npn_protocol, ossl_ssl_alpn_protocol, ossl_ssl_tmp_key): Use
	  GetSSL() instead of ossl_ssl_data_get_struct(). Use ssl_started().

	  (Init_ossl_ssl): Add method declarations of SSLSocket#{initialize,
	  hostname=}.

	* ext/openssl/ossl_ssl.h (GetSSL): Check that the SSL is not NULL. It
	  should not be NULL because we now set it in #initialize.

	* ext/openssl/ossl_ssl_session.c (ossl_ssl_session_initialize): No need
	  to check if the SSL is NULL.

Sat May 28 10:47:40 2016  SHIBATA Hiroshi  <hsbt@ruby-lang.org>

Fri May 27 01:00:36 2016  NARUSE, Yui  <naruse@ruby-lang.org>

	* symbol.c (is_identchar): use ISDIGIT instead of rb_enc_isalnum.
	  Though rb_enc_isalnum is encoding aware function, its argument here
	  is *m, which is a single byte. Therefore ISDIGIT is faster.

	* symbol.c (is_special_global_name): ditto.

	* vm_insnhelper.c (vm_getivar): specify inline instead of static inline.
	  vm_getivar is called by vm_call_ivar and vm_getinstancevariable.
	  At least with GCC 4.8 and 5.3 on Linux, they are inlining it into

	  By `inline`, they correctly inline it and gains performance.

	  and C99. Old GCC's inline means C99's extern inline.

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.

Wed Mar  9 09:19:55 2016  Rei Odaira  <Rei.Odaira@gmail.com>

	* test/io/wait/test_io_wait.rb (test_wait_readwrite_timeout):
	  select(2) in AIX returns "readable" for the write-side fd
	  of a pipe, so it is not possible to use a pipe to test
	  the read-write timeout of IO#wait on AIX.

Wed Mar  9 03:35:22 2016  Charles Oliver Nutter  <headius@headius.com>

	* win32/win32.c (rb_w32_write_console): stop the VT100 emulation if the

Tue Mar  8 08:13:01 2016  Rei Odaira  <Rei.Odaira@gmail.com>

	* test/net/imap/test_imap.rb (test_idle_timeout): Because of the
	  timeout specified in "imap.idle(0.2)", there is no guarantee that
	  the server thread has done all the work before the client thread
	  performs the assertions. It depends on the thread scheduling.
	  Add checks to avoid false positives (on AIX, particularly).

Tue Mar  8 00:42:22 2016  NAKAMURA Usaku  <usa@ruby-lang.org>

	* ruby.c (warn_cr_in_shebang): meaningless check on DOSISH platforms.

Mon Mar  7 01:38:41 2016  Rei Odaira  <Rei.Odaira@gmail.com>

	* test/ruby/test_process.rb (test_execopts_gid): Skip a test
	  that is known to fail on AIX. AIX allows setgid to
	  a supplementary group, but Ruby does not allow the "-e"
	  option when setgid'ed, so the test does not work as intended.

Sun Mar  6 22:43:41 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

	* io.c (rb_obj_display): [DOC] fix output of Array, as Array#to_s

Sat Mar  5 09:50:58 2016  Rei Odaira  <Rei.Odaira@gmail.com>

	* test/socket/test_addrinfo.rb (test_ipv6_address_predicates):
	  IN6_IS_ADDR_V4COMPAT and IN6_IS_ADDR_V4MAPPED are broken
	  on AIX, so skip related tests.

Sat Mar  5 09:17:54 2016  Rei Odaira  <Rei.Odaira@gmail.com>

	* test/rinda/test_rinda.rb (test_make_socket_ipv4_multicast):
	  The fifth argument to getsockopt(2) should be modified to
	  indicate the actual size of the value on return,
	  but not in AIX. This is a know bug. Skip related tests.
	* test/rinda/test_rinda.rb (test_ring_server_ipv4_multicast):
	  ditto.
	* test/rinda/test_rinda.rb (test_make_socket_unicast): ditto.
	* test/socket/test_basicsocket.rb (test_getsockopt): ditto.
	* test/socket/test_sockopt.rb (test_bool): ditto.

Sat Mar  5 07:36:27 2016  Rei Odaira  <Rei.Odaira@gmail.com>

	* test/-ext-/float/test_nextafter.rb: In AIX,
	  nextafter(+0.0,-0.0)=+0.0, and nextafter(-0.0,+0.0)=-0.0,
	  but they should return -0.0 and +0.0, respectively. This is
	  a known bug in nextafter(3) on AIX, so skip related tests.

Sat Mar  5 07:14:10 2016  Rei Odaira  <Rei.Odaira@gmail.com>

	* test/zlib/test_zlib.rb (test_adler32_combine, test_crc32_combine):
	  Skip two tests on AIX because zconf.h in zlib does not correctly
	  recognize _LARGE_FILES in AIX. The problem was already reported
	  to zlib, and skip these tests until it is fixed.

Sat Mar  5 03:07:40 2016  Rei Odaira  <Rei.Odaira@gmail.com>

	* thread_pthread.c (getstack): __pi_stacksize returned by
	  pthread_getthrds_np() is wrong on AIX. Use
	  __pi_stackend - __pi_stackaddr instead.

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).

	* gc.c (gc_mode_set): same macro for setter.

Tue Jan 12 19:52:19 2016  sorah (Shota Fukumori)  <her@sorah.jp>

	* 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.
