-	* ext/digest, test/digest/test_digest.rb: Merge from trunk:
-	  - Introduce versioning in Digest::Base API, and prefix C
-	    constants with RUBY_ and C type names with rb_ to avoid name
-	    clash in writing extensions.
-	  - Introduce Digest::Class and Digest::Instance for ease of
-	    implementing subclasses and add-ons.
-	  - Digest::Instance module requires and assumes that any instance
-	    be resettable and clonable.  An instance method #new() is
-	    added so digest instances work just like digest classes.
-	  - The constructor does no longer take an initial string to feed;
-	    digest() and hexdigest() now do, instead.  This allows digest
-	    classes to take their own hashing parameters.
-	  - Make some changes to digest() and hexdigest() class methods,
-	    which now take extra arguments, which are passed through to
-	    the constructor in an internal call.
-	  - Add #digest_length/size/length() and #block_length(),
-	  - Add the Digest::SHA2 class to wrap up SHA2 variants: SHA256,
-	    SHA384 and SHA512, hoping this module would make a decent
-	    example of a digest subclass written in Ruby.
-	  - Rip BubbleBabble support out of the base class and have a
-	    separate module named digest/bubblebabble.
-	  - Remove RD documents in favor of newly written and embedded
-	    RDoc documentation.
+	* vm_insnhelper.c (vm_call_method): a method entry refers the based
+	  class/module, so should search superclass from the origin i-class
+	  where the entry belongs to, to get rid of infinite loop when zsuper
+	  in a prepended class/module.  [ruby-core:54105] [Bug #8238]

-	* lib/net/http.rb: #use_ssl?, #use_ssl are moved from net/https.
+	* vm.c: support variable VM/Machine stack sizes.
+	  Specified by the following environment variables:
+	    - RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
+	      default: 128KB (32bit CPU) or 256KB (64bit CPU).
+	    - RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
+	      creation. default: 512KB or 1024KB.
+	    - RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
+	      default: 64KB or 128KB.
+	    - RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
+	      creation. default: 256KB or 256KB.
+	  This values are specified at launched timing. You can not change
+	  these values at running time.
+	  Environ variables are only *hints* because:
+	    - They are aligned to 4KB.
+	    - They have minimum values (depend on OSs).
+	    - Machine stack settings are ignored by some OSs.
+	  Default values especially fiber stack sizes are increased.
+	  This change affect Fiber's behavior:
+	    (1) You can run more complex program on a Fiber.
+	    (2) You can not make many (thousands) Fibers because of
+	        lack of address space (on 32bit CPU).
+	  If (2) bothers you,
+	    (a) Use 64bit CPU with big memory, or
+	    (b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
+	  You need to choose correct stack size carefully. These values
+	  are completely rely on systems (OS/compiler and so on).

-	* ext/openssl/ossl.c (ossl_get_errors): new method for debugging
-	  this library.
+	* method.h: remove `VM_METHOD_TYPE_CFUNC_FRAMELESS' method type.
+	  This method type is for optimized CFUNC such as Fixnum#+ and so on.
+	  This feature is half-baked and no way to use them.
+	  [Background]
+	  Now, VM has opt_plus instructions to optimize `+' methods for
+	  some Classes (such as Fixnum, Float (flonum)). We call this
+	  type of instructions as `specialized instructions'.
+	  This simple technique improve simple program dramatically.
+	  However, we can make specialized instructions for only several
+	  types (classes) and selectors (method names) because a large
+	  instruction will be slow. In other words, this technique has no
+	  extensibility.
+	  To overcome this problem, VM_METHOD_TYPE_CFUNC_FRAMELESS was
+	  introduced (r37198). This type is a variant of CFUNC, but called
+	  their functions directly without building a method frame.
+	  Any CFUNC method can be defined as frameless methods if a method
+	  is not needed to make method frame. Frameless methods are faster
+	  as specialized instructions (a bit slower, but no need to care).
+	  No problem described at
+	  http://charlie.bz/blog/why-do-singleton-methods-make-ruby-slow
+	  because this technique doesn't see class, but see method body
+	  itself. Alias is also no problem.
+	  [Problem]
+	  However, we can't set frameless method type for polymorphic methods
+	  such as Array#[]. Necessity for method frame depends on which
+	  parameter type. For example, Fixnum#+ needs method frame if
+	  coerce is needed. Current VM_METHOD_TYPE_CFUNC_FRAMELESS is not
+	  flexible and need more tuning to introduce it.
+	  Expected behavior of frameless method type may be:
+	    result = optimized_cfunc(params); /* call optimized cfunc */
+	    if (result == Qundef) { result = normal_cfunc(); }
+	  This is why I say this feature is half-baked.
+	  We need to learn primitive method in Smalltalk more.
+	  (I heard this name at RubyConf Taiwan this month. Thanks!)
+	  [Conclusion]
+	  I remove this feature and consider again.

+	* vm_trace.c (fill_id_and_klass): TracePoint#defined_class returns
+	  singleton class. `set_trace_func' passed attached class (which is
+	  attached/modified by singleton class) by 6th block parameter if it
+	  is singleton class. Previous behavior follows this spec.
+	  However, this method named `defined_class' should return singleton
+	  class directly because singleton methods are defined in singleton
+	  class. There are no compatible issue because TracePoint is introduced
+	  after 2.0.
+	  But compatibility with `set_trace_func' is broken. This means that
+	  you can not replace all `set_trace_func' code with TracePoint
+	  without consideration of this behavior.

-	* test/openssl/test_x509store.rb: add test for errors.

+Thu Dec  6 18:23:05 2012  Shugo Maeda  <shugo@ruby-lang.org>
+
+	* revised r37993 to avoid SEGV/ILL in tests.  In r37993, a method
+	  entry with VM_METHOD_TYPE_REFINED holds only the original method
+	  definition, so ci->me is set to a method entry allocated in the
+	  stack, and it causes SEGV/ILL.  In this commit, a method entry
+	  with VM_METHOD_TYPE_REFINED holds the whole original method entry.
+	  Furthermore, rb_thread_mark() is changed to mark cfp->klass to
+	  avoid GC for iclasses created by copy_refinement_iclass().
+
+	* vm_method.c (rb_method_entry_make): add a method entry with
+	  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
+	  the target module is a refinement.  When a method entry with
+	  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
+	  the same name is searched in refinements.  If such a method is
+	  found, the method is invoked.  Otherwise, the original method in
+	  the refined class (rb_method_definition_t::body.orig_me) is
+	  invoked.  This change is made to simplify the normal method lookup
+	  and to improve the performance of normal method calls.
+
+	* vm_method.c (EXPR1, search_method, rb_method_entry),
+	  vm_eval.c (rb_call0, rb_search_method_entry): do not use
+	  refinements for method lookup.
+
+	* vm_insnhelper.c (vm_call_method): search methods in refinements if
+	  ci->me is VM_METHOD_TYPE_REFINED.  If the method is called by
+	  super (i.e., ci->call == vm_call_super_method), skip the same
+	  method entry as the current method to avoid infinite call of the
+	  same method.
+
+	* class.c (include_modules_at): add a refined method entry for each
+	  method defined in a module included in a refinement.
+
+	* class.c (rb_prepend_module): set an empty table to
+	  RCLASS_M_TBL(klass) to add refined method entries, because
+	  refinements should have priority over prepended modules.
+
+	* proc.c (mnew): use rb_method_entry_with_refinements() to get
+	  a refined method.
+
+	* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
+	  copy_refinement_iclass().
+
+	* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.
+
+	* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip

+
+	* test/ruby/test_refinement.rb (test_redefine_refined_method): new

+	* vm_core.h, vm_insnhelper.c, vm_eval.c (OPT_CALL_CFUNC_WITHOUT_FRAME):

+	  This optimization makes all cfunc method calls `frameless', which
+	  is faster than ordinal cfunc method call.
+	  If `frame' is needed (for example, it calls another method with
+	  `rb_funcall()'), then build a frame. In other words, this
+	  optimization delays frame building.
+	  However, to delay the frame building, we need additional overheads:
+	    (1) Store the last call information.
+	    (2) Check the delayed frame building before the frame is needed.
+	    (3) Overhead to build a delayed frame.
+	  rb_thread_t::passed_ci is storage of delayed cfunc call information.
+	  (1) is lightweight because it is only 1 assignment to `passed_ci'.
+	  To achieve (2), we modify GET_THREAD() to check `passed_ci' every
+	  time. It causes 10% overhead on my environment.
+	  This optimization only works for cfunc methods which do not need
+	  their `frame'.
+	  After evaluation on my environment, this optimization does not
+	  effective every time. Because of this evaluation results, this
+	  optimization is disabled at default.

-	* ext/tk/tkutil.c (cbsubst_get_all_subst_keys): fix SEGV
+	* iseq.c, vm_eval.c: set th->base_block properly.
+	  th->base_block is information for (a) parsing, (b) compiling
+	  and (c) setting up the frame to execute the program passed by
+	  `eval' method.  For example, (1) parser need to know up-level
+	  variables to detect it is variable or method without paren.
+	  Befor (a), (b) and (c), VM set th->base_block by passed bindng
+	  (or previous frame information).  After execute (a), (b) and (c),
+	  VM should clear th->base_block.  However, if (a), (b) or (c)
+	  raises an exception, then th->base_block is not cleared.
+	  Problem is that the uncleared value th->balo_block is used for
+	  irrelevant iseq compilation.  It causes SEGV or critical error.
+	  I tried to solve this problem: to clear them before exception,
+	  but finally I found out that it is difficult to do it (Ruby
+	  program can be run in many places).
+	  Because of this background, I set th->base_block before
+	  compiling iseq and restore it after compiling.
+	  Basically, th->base_block is dirty hack (similar to global
+	  variable) and this patch is also dirty.

+	    then also VM loop should be escaped.  `finish frame' has only
+	    one instruction `finish', which returns VM loop function.
+	    VM loop function executes `finish' instruction, then VM loop
+	    function returns itself.
+	    With such mechanism, `leave' instruction (which returns one
+	    frame from current scope) doesn't need to check that this `leave'
+	    should also return from VM loop function.
+	    Strictly, one branch can be removed from `leave' instruction.
+	  Consideration:
+	    However, pushing the `finish frame' needs costs because
+	    it needs several memory accesses.  The number of pushing
+	    `finish frame' is greater than I had assumed.  Of course,
+	    pushing `finish frame' consumes additional control frame.
+	    Moreover, recent processors has good branch prediction,
+	    with which we can ignore such trivial checking.
+	  After this commit:
+	    Finally, I decide to remove `finish frame' and `finish'
+	    instruction.  Some parts of VM depend on `finish frame',
+	    so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
+	    If this frame should escape from VM function loop, then
+	    the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
+	    `leave' instruction checks this flag every time.
+	    I measured performance on it.  However on my environments,
+	    it improves some benchmarks and slows some benchmarks down.
+	    Maybe it is because of C compiler optimization parameters.
+	    I'll re-visit here if this cause problems.

+	* vm_core.h: remove lfp (local frame pointer) and rename
+	  dfp (dynamic frame pointer) to ep (environment pointer).
+	  This change make VM `normal' (similar to other interpreters).
+	  Before this commit:
+	    Each frame has two env pointers lfp and dfp.  lfp points
+	    local environment which is method/class/toplevel frame.
+	    lfp[0] is block pointer.
+	    dfp is block local frame. dfp[0] points previous (parent)
+	    environment pointer.
+	    lfp == dfp when frame is method/class/toplevel.
+	    You can get lfp from dfp by traversing previous environment
+	    pointers.
+	  After this commit:
+	    Each frame has only `ep' to point respective environment.
+	    If there is parent environment, then ep[0] points parent
+	    environment (as dfp).  If there are no more environment,
+	    then ep[0] points block pointer (as lfp).  We call such ep
+	    as `LEP' (local EP).  We add some macros to get LEP and to
+	    detect LEP or not.
+	    In short, we replace dfp and lfp with ep and LEP.
+	  rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
+	  and member `ep' is added.
+	  rename rb_thread_t's member `local_lfp' and `local_svar' to

-	* lib/csv.rb (CSV.parse): [CAUTION] behavior changed.  in the past,
-	  CSV.parse accepts a filename to be read-opened (it was just a
-	  shortcut of CSV.open(filename, 'r')).  now CSV.parse accepts a
-	  string or a stream to be parsed e.g.
-	  CSV.parse("1,2\n3,r") #=> [['1', '2'], ['3', '4']]
+	* ext/openssl/ossl_ssl.c: Allow disabling client-side renegotiation.
+	* test/openssl/test_ssl.rb: Simple tests for this.
 
-	* lib/csv.rb: CSV::Row and CSV::Cell are deprecated.  these classes
-	  are removed in the future.  in the new csv.rb, row is represented
-	  as just an Array.  since CSV::Row was a subclass of Array, it won't
-	  hurt almost all programs except one which depended CSV::Row#match.
-	  and a cell is represented as just a String or nil(NULL).  this
-	  change will cause widespread destruction.
+	  Client-side renegotiation is still considered problematic, even
+	  when used in the context of secure renegotiation (RI, RFC 5746).
+	  The changes allow users to either completely disable client
+	  renegotiation on the server, or to specify a maximum number of
+	  handshakes allowed in total. The number of total handshakes is
+	  counted in a callback set as SSL_set_info_callback. If the
+	  maximum number of handshakes is exceeded an error will be raised
+	  We do not support renegotiation in the OpenSSL extension, therefore
+	  this feature can only be tested externally.
+	  The feature is opt-in, the default setting will be to allow
+	  unlimited client renegotiation, as was the case before.

-	* lib/csv.rb: accepts String as a fs (field separator/column separator)

+	  (2) remove rb_backtrace_each().  Use backtrace_each() instead.
+	  (3) change the type of lev parameter to size_t.
+	      a) lev == 0 means current frame (exception, etc use it).
+	      b) lev == 1 means upper frame (caller(0) use it).

+	  [ruby-trunk - Feature #6236]
+	* test/webrick/test_server.rb:  Test for new exception handling
+	  behavior.  Join the server thread instead of busy-waiting for it to
+	  shut down to remove race conditions.
 
-	* lib/rdoc/generators/html_generator.rb: Deal with :stopdoc: when
-	  choosing a default main page to display (ie. don't select a page
-	  if we don't have documentation for it).

-	* lib/rdoc/parsers/parse_c.rb (RDoc::C_Parser::do_aliases): Handle
-	  aliases in C files.

+	  option to prevent BEAST attack. See [Bug #5353].
+
+	  In OpenSSL, OP_DONT_INSERT_EMPTY_FRAGMENTS is used to prevent
+	  TLS-CBC-IV vulnerability described at
+	  http://www.openssl.org/~bodo/tls-cbc.txt
+	  It's known issue of TLSv1/SSLv3 but it attracts lots of attention
+	  these days as BEAST attack. (CVE-2011-3389)
+
+	  Until now ossl sets OP_ALL at SSLContext allocation and call
+	  SSL_CTX_set_options at connection.  SSL_CTX_set_options updates the
+	  value by using |= so bits set by OP_ALL cannot be unset afterwards.
+
+	  This commit changes to call SSL_CTX_set_options only 1 time for each
+	  SSLContext. It sets the specified value if SSLContext#options= are
+	  called and sets OP_ALL if not.
+
+	  To help users to unset bits in OP_ALL, this commit also adds several
+	  constant to SSL such as
+	  OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.  These constants were
+	  not exposed in Ruby because there's no way to unset bits in OP_ALL
+	  before.
+
+	  Following is an example to enable 0/n split for BEAST prevention.
+
+	    ctx.options = OP_ALL & ~OP_DONT_INSERT_EMPTY_FRAGMENTS
+
+	* test/openssl/test_ssl.rb: Test above option exists.

-	  NextStep since, on some installations, this value always resolves
-	  uselessly to zero.
+	* io.c (ioctl_req_t): Type of req argument of ioctl() depend on platform.
+	  Moreover almost all linux ioctl can't be represented by 32bit integer
+	  (i.e. MSB is 1). We need wrap ioctl argument type.
+	  [Bug #5429] [ruby-dev:44589]
+	* io.c (struct ioctl_arg): ditto.
+	* io.c (rb_ioctl): ditto.
+	* test/ruby/test_io.rb (test_ioctl_linux): add a testcase for ioctl
 
-	* dln.c: added error reporting to NextStep extension loader since the
-	  previous behavior of failing silently was not useful; now ensures
-	  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
-	  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
-	  on Rhapsody since this header lacks multiple-include protection,
-	  which resulted in "redefinition" compilation errors.

-	* main.c: also create hard reference to objc_msgSend() on NeXT
-	  platforms (in addition to Apple platforms).
+	* io.c (struct io_cntl_arg): remove io_p member.
+	* io.c (nogvl_fcntl, do_fcntl, rb_fcntl): separated from ioctl functions.
+	* io.c (nogvl_io_cntl): remove fcntl depended logic.

-	* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
-	  makefiles so that extensions can be built MAB (see configure's
-	  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
-	  (but not cpp_command() because MAB flags are incompatible with
-	  direct invocation of `cpp').
+Sat Nov 12 10:59:49 2011  KOSAKI Motohiro  <kosaki.motohiro@gmail.com>
 
-	* ext/curses/extconf.rb: now additionally checks for presence of these
-	  curses functions which are not present on NextStep or Openstep:
-	  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
-	  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
-	  wscrl(), wsetscrreg()
+	* io.c (setup_narg): fix off by one bug.
 
-	* ext/curses/curses.c: added appropriate #ifdef's for additional set of
-	  curses functions now checked by extconf.rb; fixed curses_bkgd() and
-	  window_bkgd() to correctly return boolean result rather than numeric
-	  result; fixed window_getbkgd() to correctly signal an error by
-	  returning nil rather than -1.
+Sat Nov 12 10:56:43 2011  KOSAKI Motohiro  <kosaki.motohiro@gmail.com>
 
-	* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
-	  pointers before invoking rb_tainted_str_new2() upon fields extracted
-	  from `struct passwd' and `struct group' since null pointers in some
-	  fields are common on NextStep/OpenStep (especially so for the
-	  `pw_comment' field) and rb_tainted_str_new2() throws an exception
-	  when it receives a null pointer.
+	* io.c (+setup_narg): factor out length calculation logic.
+	* io.c (rb_io_ctl): ditto.
 
-	* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup().
+Sat Nov 12 10:52:17 2011  KOSAKI Motohiro  <kosaki.motohiro@gmail.com>
 
-	* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
-	  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
-	  (char*) for older platforms such as NextStep and OpenStep.
+	* io.c (+ioctl_narg_len) new helper function.
+	* io.c (rb_io_ctl): don't use ioctl specific length check
+	  if caller is fcntl.
 
-	* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup(); include
-	  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
-	  argument of gethostbyaddr() and getservbyname() from (const char*) to

+
+Fri Aug 26 19:12:08 2011  Hiroshi Nakamura  <nahi@ruby-lang.org>
+
+	* variable.c: Make autoload thread-safe. See #921.
+
+	  What's the problem?
+	    autoload is thread unsafe. When we define a constant to be
+	    autoloaded, we expect the constant construction is invariant. But
+	    current autoload implementation allows other threads to access the
+	    constant while the first thread is loading a file.
+
+	  What's happening inside?
+	    The current implementation uses Qundef as a marker of autoload in
+	    Constant table. Once the first thread find Qundef as a value at
+	    constant lookup, it starts loading a defined feature. Generally a
+	    loaded file overrides the Qundef in Constant table by module/class
+	    declaration at very beginning lines of the file, so other threads
+	    can see the new Module/Class object before feature loading is
+	    finished. It breaks invariant construction.
+
+	  How to solve?
+	    To ensure invariant constant construction, we need to override
+	    Qundef with defined Object after the feature loading. For keeping
+	    Qundef in Constant table, I expanded autoload_data struct in
+	    Module to have a slot for keeping the defined object while feature
+	    loading. And changed Module's constant lookup/update logic a
+	    little so that the slot is only visible from the thread which
+	    invokes feature loading. (== the first thread which accessed the
+	    autoload constant)
+
+	  Evaluation?
+	    All test passes (bootstrap test, test-all and RubySpec) and added
+	    8 tests for threading behavior. Extra logics are executed only
+	    when Qundef is found, so no perf drop should happen except
+	    autoloading.
+
+	* variable.c (rb_autoload): Prepare new autoload_data struct.
+
+	* variable.c (rb_autoload_load): Load feature and update Constant
+	  table after feature loading is finished.
+
+	* variable.c (rb_const_get_0): When the fetched constant is under

+	  autoloading.
+
+	* variable.c (rb_const_defined_0): Ditto.
+
+	* variable.c (rb_const_set): When the specified constant is under
+	  autoloading, it sets the object only for the thread which starts
+	  autoloading. Otherwise, simply overrides Qundef with constant
+	  override warning.
+
+	* vm_insnhelper.c (vm_get_ev_const): Apply same change as

+	  This problem is caused by changing dfp (dynamic env pointer)
+	  from saved dfp.  Saved dfp is pointed env in VM stack.  However,
+	  the dfp can be moved because VM copies env from VM stack to
+	  the heap.  At this copying, dfp was also changed.  To solve this

-		  GNU LESSER GENERAL PUBLIC LICENSE
-		       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+      File::FNM_EXTGLOB option is given.
+
+* GC
+  * improvements:

+      with Copy-on-Write.
+    * introduced the non-recursive marking which avoids unexpected stack overflow.

+    * system() and exec() closes non-standard file descriptors
+      (The default of :close_others option is changed to true by default.)
+    * respond_to? against a protected method now returns false unless
+      the second argument is true.
+    * __callee__ has returned to the original behavior, and now
+      returns the called name but not the original name in an
+      aliased method.
+    * Kernel#inspect does not call #to_s anymore
+      (it used to call redefined #to_s).
+
+* LoadError
+  * added method:
+    * added LoadError#path method to return the file name that could not be
+      loaded.
+
+* Module
+  * added method:
+    * added Module#prepend which is similar to Module#include,
+      however a method in the prepended module overrides the
+      corresponding method in the prepending module.
+    * added Module.prepended and Module.prepend_features, similar
+      to included and append_features.
+    * added Module#refine, which extends a class or module locally.
+      [experimental]
+  * extended method:
+    * Module#define_method accepts a UnboundMethod from a Module.
+    * Module#const_get accepts a qualified constant string, e.g.
+      Object.const_get("Foo::Bar::Baz")
+
+* Mutex
+  * added method:
+    * added Mutex#owned? which returns the mutex is held by current
+      thread or not. [experimental]
+  * incompatible changes:
+    * Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize
+      and Mutex#sleep are no longer allowed to be used from trap handler
+      and raise a ThreadError in such case.
+    * Mutex#sleep may spurious wakeup. Check after wakeup.
+
+* NilClass
+  * added method:
+    * added nil.to_h which returns {}
+
+* ObjectSpace::WeakMap
+  * new low level class to hold weak references to objects.
+
+* Proc
+  * incompatible change:
+    * removed Proc#== and #eql? so two procs are == only when they are
+      the same object.
+
+* Process
+  * added method:
+    * added getsid for getting session id (unix only).
+
+* Range
+  * added method:
+    * added Range#size for lazy size evaluation.
+    * added Range#bsearch for binary search.
+
+* RubyVM (MRI specific)
+  * added RubyVM::InstructionSequence.of to get the instruction sequence
+    from a method or a block.
+  * added RubyVM::InstructionSequence#path, #absolute_path, #label,
+    #base_label and #first_lineno to retrieve information from where
+    the instruction sequence was defined.
+  * added Environment variables to specify stack usage:
+    * RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
+      default: 128KB (32bit CPU) or 256KB (64bit CPU).
+    * RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
+      creation. default: 512KB or 1024KB.
+    * RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
+      default: 64KB or 128KB.
+    * RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
+      creation. default: 256KB or 256KB.
+    These variables are checked only at launched time.
+  * added constant DEFAULT_PARAMS to get above default parameters.
+
+* Signal
+  * added method:
+    * added Signal.signame which returns signal name
+
+  * incompatible changes:
+    * Signal.trap raises ArgumentError when :SEGV, :BUS, :ILL, :FPE, :VTALRM
+      are specified.
+
+* String
+  * added method:
+    * added String#b returning a copied string whose encoding is ASCII-8BIT.
+  * change return value:
+    * String#lines now returns an array instead of an enumerator.
+    * String#chars now returns an array instead of an enumerator.
+    * String#codepoints now returns an array instead of an enumerator.
+    * String#bytes now returns an array instead of an enumerator.
+
+* Struct
+  * added method:
+    * added Struct#to_h returning values with keys corresponding to the
+      instance variable names.
+
+* Thread
+  * added method:
+    * added Thread#thread_variable_get for getting thread local variables
+      (these are different than Fiber local variables).
+    * added Thread#thread_variable_set for setting thread local variables.
+    * added Thread#thread_variables for getting a list of the thread local
+      variable keys.
+    * added Thread#thread_variable? for testing to see if a particular thread
+      variable has been set.
+    * added Thread.handle_interrupt as well as instance and singleton methods
+      pending_interrupt? for asynchronous handling of exceptions
+    * added Thread#backtrace_locations which returns similar information of
+      Kernel#caller_locations.
+  * new class Thread::Backtrace::Location to hold backtrace location
+    information. These are returned by Thread#backtrace_locations and
+    Kernel#caller_locations.
+  * incompatible changes:
+    * Thread#join and Thread#value now raises a ThreadError if target thread
+      is the current or main thread.
+
+* Time
+  * change return value:
+    * Time#to_s now returns US-ASCII encoding instead of BINARY.
+
+* TracePoint
+  * new class. This class is replacement of set_trace_func.
+    Easy to use and efficient implementation.
+
+* toplevel
+  * added method:
+    * added main.define_method which defines a global function.
+    * added main.using, which imports refinements into the current file or
+      eval string. [experimental]

+  These methods no longer return an Enumerator, although passing a
+  block is still supported for backwards compatibility.
+
+  Code like str.lines.with_index(1) { |line, lineno| ... } no longer
+  works because str.lines returns an array.  Replace lines with
+  each_line in such cases.
+
+* IO#lines
+* IO#chars
+* IO#codepoints
+* IO#bytes
+* ARGF#lines
+* ARGF#chars
+* ARGF#bytes
+* StringIO#lines
+* StringIO#chars
+* StringIO#codepoints
+* StringIO#bytes
+* Zlib::GzipReader#lines
+* Zlib::GzipReader#bytes
+
+  These methods are deprecated in favor of each_line, each_byte,
+  each_char and each_codepoint.
+
+* Proc#==
+* Proc#eql?
+
+  These methods were removed. Two procs are == only when they are
+  the same object.
+
+* Fixnum
+* Bignum
+* Float
+
+  Fixnums, Bignums and Floats are frozen.
+
+* Signal.trap
+
+  See above.
+
+* Merge Onigmo.
+  https://github.com/k-takata/Onigmo
+
+* The :close_others option is true by default for system() and exec().
+  Also, the close-on-exec flag is set by default for all new file descriptors.
+  This means file descriptors doesn't inherit to spawned process unless
+  explicitly requested such as system(..., fd=>fd).
+
+* Kernel#respond_to? against a protected method now returns false
+  unless the second argument is true.
+
+* Kernel#respond_to_missing?
+* Kernel#initialize_clone
+* Kernel#initialize_dup
+
+  These methods are now private.
+
+* Thread#join, Thread#value
+
+  See above.
+
+* Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep
+
+  See above.
+
+=== Stdlib updates (outstanding ones only)
+
+* cgi
+  * Add HTML5 tag maker.
+  * CGI#header has been renamed to CGI#http_header and
+    aliased to CGI#header.
+  * When HTML5 tagmaker called, overwrite CGI#header,
+    CGI#header function is to create a <header> element.
+
+* CSV
+  * Removed CSV::dump and CSV::load to protect users from dangerous
+    serialization vulnerability
+
+* iconv
+  * Iconv has been removed. Use String#encode instead.
+
+* io/console
+  * new methods:
+    * added IO#cooked which sets the terminal to cooked mode within the given block.
+    * added IO#cooked! which sets the terminal to cooked.
+  * extended method:
+    * IO#raw, IO#raw!, and IO#getch accept keyword arguments, :min and :time.
+
+* io/wait
+  * new features:
+    * added IO#wait_writable method.
+    * added IO#wait_readable method as alias of IO#wait.
+
+* json
+  * updated to 1.7.7.
+
+* net/http
+  * new features:
+    * Proxies are now automatically detected from the http_proxy environment
+      variable.  See Net::HTTP::new for details.
+    * gzip and deflate compression are now requested for all requests by
+      default.  See Net::HTTP for details.
+    * SSL sessions are now reused across connections for a single instance.
+      This speeds up connection by using a previously negotiated session.
+    * Requests may be created from a URI which sets the request_uri and host
+      header of the request (but does not change the host connected to).
+    * Responses contain the URI requested which allows easier implementation of
+      redirect following.
+  * new methods:
+    * Net::HTTP#local_host
+    * Net::HTTP#local_host=
+    * Net::HTTP#local_port
+    * Net::HTTP#local_port=
+  * extended method:
+    * Net::HTTP#connect uses local_host and local_port if specified.
+
+* net/imap
+  * new methods:
+    * Net::IMAP.default_port
+    * Net::IMAP.default_imap_port
+    * Net::IMAP.default_tls_port
+    * Net::IMAP.default_ssl_port
+    * Net::IMAP.default_imaps_port
+
+* objspace
+  * new method:
+    * ObjectSpace.reachable_objects_from(obj)
+
+* openssl
+  * Consistently raise an error when trying to encode nil values. All instances
+    of OpenSSL::ASN1::Primitive now raise TypeError when calling to_der on an
+    instance whose value is nil. All instances of OpenSSL::ASN1::Constructive
+    raise NoMethodError in the same case. Constructing such values is still
+    permitted.
+  * TLS 1.1 & 1.2 support by setting OpenSSL::SSL::SSLContext#ssl_version to
+    :TLSv1_2, :TLSv1_2_server, :TLSv1_2_client or :TLSv1_1, :TLSv1_1_server
+    :TLSv1_1_client. The version being effectively used can be queried
+    with OpenSSL::SSL#ssl_version. Furthermore, it is also possible to
+    blacklist the new TLS versions with OpenSSL::SSL:OP_NO_TLSv1_1 and
+    OpenSSL::SSL::OP_NO_TLSv1_2.
+  * Added OpenSSL::SSL::SSLContext#renegotiation_cb. A user-defined callback
+    may be set which gets called whenever a new handshake is negotiated. This
+    also allows to programmatically decline (client) renegotiation attempts.
+  * Support for "0/n" splitting of records as BEAST mitigation via
+    OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.
+  * The default options for OpenSSL::SSL::SSLContext have changed to
+    OpenSSL::SSL::OP_ALL & ~OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS
+    instead of OpenSSL::SSL::OP_ALL only. This enables the countermeasure for
+    the BEAST attack by default.
+  * OpenSSL requires passwords for decrypting PEM-encoded files to be at least
+    four characters long. This led to awkward situations where an export with
+    a password with fewer than four characters was possible, but accessing the
+    file afterwards failed. OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and
+    OpenSSL::PKey::EC therefore now enforce the same check when exporting a
+    private key to PEM with a password - it has to be at least four characters
+    long.
+  * SSL/TLS support for the Next Protocol Negotiation extension. Supported
+    with OpenSSL 1.0.1 and higher.
+  * OpenSSL::OPENSSL_FIPS allows client applications to detect whether OpenSSL
+    is FIPS-enabled. OpenSSL.fips_mode= allows turning on and off FIPS mode
+    manually in order to adapt to situations where FIPS mode would be an
+    explicit requirement.
+  * Authenticated Encryption with Associated Data (AEAD) is supported via
+    Cipher#auth_data= and Cipher#auth_tag/Cipher#auth_tag=.
+    Currently (OpenSSL 1.0.1c), only GCM mode is supported.
+
+* ostruct
+  * new methods:
+    * OpenStruct#[], []=
+    * OpenStruct#each_pair
+    * OpenStruct#eql?
+    * OpenStruct#hash
+    * OpenStruct#to_h converts the struct to a hash.
+  * extended method:
+    * OpenStruct.new also accepts an OpenStruct / Struct.
+
+* pathname
+  * extended method:
+    * Pathname#find returns an enumerator if no block is given.
+
+* rake
+  * rake has been updated to version 0.9.5.
+
+    This version is backwards-compatible with previous rake versions and
+    contains many bug fixes.
+
+    See
+    http://rake.rubyforge.org/doc/release_notes/rake-0_9_5_rdoc.html for a list
+    of changes in rake 0.9.3, 0.9.4 and 0.9.5.
+
+* RDoc
+  * RDoc has been updated to version 4.0
+
+    This version is largely backwards-compatible with previous rdoc versions.
+    The most notable change is an update to the ri data format (ri data must
+    be regenerated for gems shared across rdoc versions).  Further API changes
+    are internal and won't affect most users.
+
+    Notable changes include:
+
+    * Page support for ri.  Try `ri ruby:` for a list of pages in ruby or
+      `ri ruby:syntax/literals` for the syntax documentation for literals.
+
+      This also works for gems such as `ri rspec:README` for the rspec gem's
+      README file.
+    * Markdown support.  See ri RDoc::Markdown for details.
+
+    See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a full list
+    of changes in rdoc 4.0.
+
+* resolv
+  * new methods:
+    * Resolv::DNS#timeouts=
+    * Resolv::DNS::Config#timeouts=
+
+* rexml
+  * REXML::Document#write supports Hash arguments.
+  * REXML::Document#write supports new :encoding option. It changes
+    XML document encoding. Without :encoding option, encoding in
+    XML declaration is used for XML document encoding.
+
+* RubyGems
+  * Updated to 2.0.14.
+
+    See http://rubygems.rubyforge.org/rubygems-update/History_txt.html#label-2.0.14+%2F+2013-11-12
+    for release notes.
+
+  * Updated to 2.0.10.  This fixes CVE_2013-4363:
+
+    http://rubygems.rubyforge.org/rubygems-update/CVE-2013-4363_txt.html
+
+  * Updated to 2.0.8.  This fixes CVE-2013-4287:
+
+    http://rubygems.rubyforge.org/rubygems-update/CVE-2013-4287_txt.html
+
+  * Updated to 2.0.0
+
+    RubyGems 2.0.0 features the following improvements:
+
+    * Improved support for default gems shipping with ruby 2.0.0+
+    * A gem can have arbitrary metadata through Gem::Specification#metadata
+    * `gem search` now defaults to --remote and is anchored like gem list.
+    * Added --document to replace --rdoc and --ri.  Use --no-document to
+      disable documentation, --document=rdoc to only generate rdoc.
+    * Only ri-format documentation is generated by default.
+    * `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
+      documentation.
+
+    For an expanded list of updates and bug fixes see:
+    https://github.com/rubygems/rubygems/blob/master/History.txt
+
+* shellwords
+  * Shellwords#shellescape now stringifies the given object using to_s.
+  * Shellwords#shelljoin accepts non-string objects in the given
+    array, each of which is stringified using to_s.
 
-  * New option for FileUtils.cp_r(): :remove_destination
+* stringio
+  * deprecated methods:
+    * StringIO#lines, #bytes, #chars and #codepoints are deprecated.
 
-* thread
+* syslog
+  * Added Syslog::Logger which provides a Logger API atop Syslog.
+  * Syslog::Priority, Syslog::Level, Syslog::Option and Syslog::Macros
+    are introduced for easy detection of available constants on a
+    running system.
 
-  * Replaced with much faster mutex implementation in C.
-    The former implementation is available with a
-    configure option `--disable-fastthread'.
+* tmpdir
+  * incompatible changes:
+    * Dir.mktmpdir uses FileUtils.remove_entry instead of
+      FileUtils.remove_entry_secure.  This means that applications should not
+      change the permission of the created temporary directory to make
+      accessible from other users.
 
-* webrick
+* yaml
+  * Syck has been removed.  YAML now completely depends on libyaml being
+    installed.
+  * libyaml is now bundled with ruby, for cases where the library is not
+    installed locally.
 
-  * New method: WEBrick::Cookie.parse_set_cookies()
+* zlib
+  * Added streaming support for Zlib::Inflate and Zlib::Deflate.  This allows
+    processing of a stream without the use of large amounts of memory.
+  * Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED.
+  * Zlib streams are now processed without the GVL.  This allows gzip, zlib and
+    deflate streams to be processed in parallel.
+  * deprecated methods:
+    * Zlib::GzipReader#lines and #bytes are deprecated.
 
-=== Compatibility issues (excluding feature bug fixes)
+=== Stdlib compatibility issues (excluding feature bug fixes)
 
-* builtin classes
+* OpenStruct new methods can conflict with custom attributes named
+  "each_pair", "eql?", "hash" or "to_h".
 
-  * String#intern now raises SecurityError when $SAFE level is greater
-    than zero.
+* Dir.mktmpdir in lib/tmpdir.rb
 
-* fileutils
+  See above.
 
-  * A minor implementation change breaks Rake <=0.7.1.
-    Updating Rake to 0.7.2 fixes the problem.
+=== C API updates
 
-* digest
+* NUM2SHORT() and NUM2USHORT() added. They are similar to NUM2INT, but short.
 
-  * The constructor does no longer take an initial
-    string to feed; digest() and hexdigest() now do,
-    instead.  The following examples show how to
-    migrate:
+* rb_newobj_of() and NEWOBJ_OF() added. They create a new object of a given class.
 
-      # Before
-      md = Digest::MD5.new("string")
-      # After (works with any version)
-      md = Digest::MD5.new.update("string")
-        
-      # Before
-      hd = Digest::MD5.new("string").hexdigest
-      # After (works with any version)
-      hd = Digest::MD5.hexdigest("string")

+
+The T_FIXNUM data is a 31bit or 63bit length fixed integer.
+This size is depend on the size of long: if long is 32bit then
+T_FIXNUM is 31bit, if long is 64bit then T_FIXNUM is 63bit.
+T_FIXNUM can be converted to a C integer by using the
+FIX2INT() macro or FIX2LONG().  Though you have to check that the
+data is really FIXNUM before using them, they are faster.  FIX2LONG()
+never raises exceptions, but FIX2INT() raises RangeError if the
+result is bigger or smaller than the size of int.
+There are also NUM2INT() and NUM2LONG() which converts any Ruby
+numbers into C integers.  These macros includes a type check,
+so an exception will be raised if the conversion failed.  NUM2DBL()
+can be used to retrieve the double float value in the same way.
+
+You can use the macros
 StringValue() and StringValuePtr() to get a char* from a VALUE.
 StringValue(var) replaces var's value with the result of "var.to_str()".
 StringValuePtr(var) does same replacement and returns char*
-representation of var.  These macros will skip the replacement if var is
-a String.  Notice that the macros take only the lvalue as their
+representation of var.  These macros will skip the replacement if var
+is a String.  Notice that the macros take only the lvalue as their
 argument, to change the value of var in place.
 
-In version 1.6 or earlier, STR2CSTR() was used to do the same thing
-but now it is deprecated in version 1.7, because STR2CSTR() has a risk
-of a dangling pointer problem in the to_str() impliclit conversion.
+You can also use the macro named StringValueCStr(). This is just
+like StringValuePtr(), but always add nul character at the end of
+the result. If the result contains nul character, this macro causes
+the ArgumentError exception.
+StringValuePtr() doesn't guarantee the existence of a nul at the end
+of the result, and the result may contain nul.
 
 Other data types have corresponding C structures, e.g. struct RArray

-** Hooks for the Interpreter Events
+== Invoking Ruby method
 
- void rb_add_event_hook(rb_event_hook_func_t func, rb_event_t events)
+VALUE rb_funcall(VALUE recv, ID mid, int narg, ...) ::
 
-Adds a hook function for the specified interpreter events.
-events should be Or'ed value of:
-
-	RUBY_EVENT_LINE
-	RUBY_EVENT_CLASS
-	RUBY_EVENT_END
-	RUBY_EVENT_CALL
-	RUBY_EVENT_RETURN
-	RUBY_EVENT_C_CALL
-	RUBY_EVENT_C_RETURN
-	RUBY_EVENT_RAISE
-	RUBY_EVENT_ALL
+  Invokes a method.  To retrieve mid from a method name, use rb_intern().
 
-The definition of rb_event_hook_func_t is below:
+VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv) ::
 
- typedef void (*rb_event_hook_func_t)(rb_event_t event, NODE *node,
- 				      VALUE self, ID id, VALUE klass)
+  Invokes a method, passing arguments by an array of values.
 
- int rb_remove_event_hook(rb_event_hook_func_t func)
+VALUE rb_eval_string(const char *str) ::
 
-Removes the specified hook function.
+  Compiles and executes the string as a Ruby program.
+
+ID rb_intern(const char *name) ::
+
+  Returns ID corresponding to the name.
+
+char *rb_id2name(ID id) ::
+
+  Returns the name corresponding ID.
+
+char *rb_class2name(VALUE klass) ::
+
+  Returns the name of the class.
+
+int rb_respond_to(VALUE object, ID id) ::
+
+  Returns true if the object responds to the message specified by id.
+
+== Instance Variables
+
+VALUE rb_iv_get(VALUE obj, const char *name) ::
+
+  Retrieve the value of the instance variable.  If the name is not
+  prefixed by `@', that variable shall be inaccessible from Ruby.
+
+VALUE rb_iv_set(VALUE obj, const char *name, VALUE val) ::
+
+  Sets the value of the instance variable.
+
+== Control Structure
+
+VALUE rb_block_call(VALUE recv, ID mid, int argc, VALUE * argv, VALUE (*func) (ANYARGS), VALUE data2) ::
+
+  Calls a method on the recv, with the method name specified by the
+  symbol mid, with argc arguments in argv, supplying func as the
+  block. When func is called as the block, it will receive the value
+  from yield as the first argument, and data2 as the second argument.
+  When yielded with multiple values (in C, rb_yield_values(),
+  rb_yield_values2() and rb_yield_splat()), data2 is packed as an Array,
+  whereas yielded values can be gotten via argc/argv of the third/fourth
+  arguments.
+
+[OBSOLETE] VALUE rb_iterate(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2) ::
+
+  Calls the function func1, supplying func2 as the block.  func1 will be
+  called with the argument arg1.  func2 receives the value from yield as
+  the first argument, arg2 as the second argument.
+
+  When rb_iterate is used in 1.9, func1 has to call some Ruby-level method.
+  This function is obsolete since 1.9; use rb_block_call instead.
+
+VALUE rb_yield(VALUE val) ::
 
-Appendix C. Functions Available in extconf.rb
+  Evaluates the block with value val.
 
-These functions are available in extconf.rb:
+VALUE rb_rescue(VALUE (*func1)(), VALUE arg1, VALUE (*func2)(), VALUE arg2) ::
 
- have_macro(macro, headers)
+  Calls the function func1, with arg1 as the argument.  If an exception
+  occurs during func1, it calls func2 with arg2 as the argument.  The
+  return value of rb_rescue() is the return value from func1 if no
+  exception occurs, from func2 otherwise.
 
-Checks whether macro is defined with header.  Returns true if the macro
-is defined.
+VALUE rb_ensure(VALUE (*func1)(), VALUE arg1, VALUE (*func2)(), VALUE arg2) ::
 
- have_library(lib, func)
+  Calls the function func1 with arg1 as the argument, then calls func2
+  with arg2 if execution terminated.  The return value from
+  rb_ensure() is that of func1 when no exception occured.
 
-Checks whether the library exists, containing the specified function.
-Returns true if the library exists.
+VALUE rb_protect(VALUE (*func) (VALUE), VALUE arg, int *state) ::
 
- find_library(lib, func, path...)
+  Calls the function func with arg as the argument.  If no exception
+  occured during func, it returns the result of func and *state is zero.
+  Otherwise, it returns Qnil and sets *state to nonzero.  If state is
+  NULL, it is not set in both cases.
+  You have to clear the error info with rb_set_errinfo(Qnil) when
+  ignoring the caught exception.
 
-Checks whether a library which contains the specified function exists in
-path.  Returns true if the library exists.
+void rb_jump_tag(int state) ::
 
- have_func(func, header)
+  Continues the exception caught by rb_protect() and rb_eval_string_protect().
+  state must be the returned value from those functions.  This function
+  never return to the caller.
 
-Checks whether func exists with header.  Returns true if the function
-exists.  To check functions in an additional library, you need to
-check that library first using have_library().
+void rb_iter_break() ::
 
- have_var(var, header)
+  Exits from the current innermost block.  This function never return to
+  the caller.
 
-Checks whether var exists with header.  Returns true if the variable
-exists.  To check variables in an additional library, you need to
-check that library first using have_library().
+void rb_iter_break_value(VALUE value) ::
 
- have_header(header)
+  Exits from the current innermost block with the value.  The block will
+  return the given argument value.  This function never return to the
+  caller.
 
-Checks whether header exists.  Returns true if the header file exists.
+== Exceptions and Errors
 
- find_header(header, path...)
+void rb_warn(const char *fmt, ...) ::
 
-Checks whether header exists in path.  Returns true if the header file
-exists.
+  Prints a warning message according to a printf-like format.
 
- have_struct_member(type, member, header)
+void rb_warning(const char *fmt, ...) ::
 
-Checks whether type has member with header.  Returns true if the type
-is defined and has the member.
+  Prints a warning message according to a printf-like format, if
+  $VERBOSE is true.
+
+void rb_raise(rb_eRuntimeError, const char *fmt, ...) ::
+
+  Raises RuntimeError.  The fmt is a format string just like printf().
+
+void rb_raise(VALUE exception, const char *fmt, ...) ::
+
+  Raises a class exception.  The fmt is a format string just like printf().
+
+void rb_fatal(const char *fmt, ...) ::
+
+  Raises a fatal error, terminates the interpreter.  No exception handling
+  will be done for fatal errors, but ensure blocks will be executed.
+
+void rb_bug(const char *fmt, ...) ::
+
+  Terminates the interpreter immediately.  This function should be
+  called under the situation caused by the bug in the interpreter.  No
+  exception handling nor ensure execution will be done.
+
+Note: In the format string, %i is used for Object#to_s (or Object#inspect if
+'+' flag is set) output (and related argument must be a VALUE).  For integers
+in format strings, use %d.
+
+== Initialize and Start the Interpreter
+
+The embedding API functions are below (not needed for extension libraries):
+
+void ruby_init() ::
+
+  Initializes the interpreter.
+
+void ruby_options(int argc, char **argv) ::
+
+  Process command line arguments for the interpreter.
+
+void ruby_run() ::
+
+  Starts execution of the interpreter.
+
+void ruby_script(char *name) ::
+
+  Specifies the name of the script ($0).
+
+== Hooks for the Interpreter Events
+
+  void rb_add_event_hook(rb_event_hook_func_t func, rb_event_flag_t events,
+                         VALUE data)
+
+Adds a hook function for the specified interpreter events.
+events should be OR'ed value of:
+
+  RUBY_EVENT_LINE
+  RUBY_EVENT_CLASS
+  RUBY_EVENT_END
+  RUBY_EVENT_CALL
+  RUBY_EVENT_RETURN
+  RUBY_EVENT_C_CALL
+  RUBY_EVENT_C_RETURN
+  RUBY_EVENT_RAISE
+  RUBY_EVENT_ALL
+
+The definition of rb_event_hook_func_t is below:
+
+  typedef void (*rb_event_hook_func_t)(rb_event_t event, VALUE data,
+                                       VALUE self, ID id, VALUE klass)
+
+The third argument `data' to rb_add_event_hook() is passed to the hook
+function as the second argument, which was the pointer to the current
+NODE in 1.8.  See RB_EVENT_HOOKS_HAVE_CALLBACK_DATA below.
+
+  int rb_remove_event_hook(rb_event_hook_func_t func)
+
+Removes the specified hook function.
 
- have_type(type, header, opt)
+== Macros for Compatibility
 
-Checks whether type is defined with header.  Returns true if the type
-is defined.
+Some macros to check API compatibilities are available by default.
 
- check_sizeof(type, header)
+NORETURN_STYLE_NEW ::
 
-Checks the size of type in char with header.  Returns the size if the
-type is defined, otherwise nil.
+  Means that NORETURN macro is functional style instead of prefix.
 
- create_makefile(target)
+HAVE_RB_DEFINE_ALLOC_FUNC ::
 
-Generates the Makefile for the extension library.  If you don't invoke
-this method, the compilation will not be done.
+  Means that function rb_define_alloc_func() is provided, that means the
+  allocation framework is used.  This is same as the result of
+  have_func("rb_define_alloc_func", "ruby.h").
 
- find_executable(bin, path)
+HAVE_RB_REG_NEW_STR ::
 
-Finds command in path, which is File::PATH_SEPARATOR-separated list of
-directories.  If path is nil or omitted, environment varialbe PATH
-will be used.  Returns the path name of the command if it is found,
-otherwise nil.
+  Means that function rb_reg_new_str() is provided, that creates Regexp
+  object from String object.  This is same as the result of
+  have_func("rb_reg_new_str", "ruby.h").
 
- with_config(withval[, default=nil])
+HAVE_RB_IO_T ::
 
-Parses the command line options and returns the value specified by
---with-<withval>.
+  Means that type rb_io_t is provided.
 
- enable_config(config, *defaults)
- disable_config(config, *defaults)
+USE_SYMBOL_AS_METHOD_NAME ::
 
-Parses the command line options for boolean.  Returns true if
---enable-<config> is given, or false if --disable-<config> is given.
-Otherwise, yields defaults to the given block and returns the result
-if it is called with a block, or returns defaults.
+  Means that Symbols will be returned as method names, e.g.,
+  Module#methods, #singleton_methods and so on.
 
- dir_config(target[, default_dir])
- dir_config(target[, default_include, default_lib])
+HAVE_RUBY_*_H ::
 
-Parses the command line options and adds the directories specified by
---with-<target>-dir, --with-<target>-include, and/or --with-<target>-lib
-to $CFLAGS and/or $LDFLAGS.  --with-<target>-dir=/path is equivalent to
---with-<target>-include=/path/include --with-<target>-lib=/path/lib.
-Returns an array of the added directories ([include_dir, lib_dir]).
+  Defined in ruby.h and means corresponding header is available.  For
+  instance, when HAVE_RUBY_ST_H is defined you should use ruby/st.h not
+  mere st.h.
 
- pkg_config(pkg)
+RB_EVENT_HOOKS_HAVE_CALLBACK_DATA ::
 
-Obtains the information for pkg by pkg-config command.  The actual
-command name can be overriden by --with-pkg-config command line
-option.
+  Means that rb_add_event_hook() takes the third argument `data', to be
+  passed to the given event hook function.

+に置き換えるマクロ，StringValuePtr(var) は同様に var を
+String に置き換えてから var のバイト列表現に対する char* を
+返すマクロです．var の内容を直接置き換える処理が入るので，
+var は lvalue である必要があります．
+また，StringValuePtr() に類似した StringValueCStr() というマ
+クロもあります．StringValueCStr(var) は var を String に置き
+換えてから var の文字列表現に対する char* を返します．返され
+る文字列の末尾には nul 文字が付加されます．なお，途中に nul
+文字が含まれる場合は ArgumentError が発生します．
+一方，StringValuePtr() では，末尾に nul 文字がある保証はなく，
+途中に nul 文字が含まれている可能性もあります．

+= Rubyの機能を使う
+
+原理的にRubyで書けることはCでも書けます．RubyそのものがCで記
+述されているんですから，当然といえば当然なんですけど．ここで
+はRubyの拡張に使うことが多いだろうと予測される機能を中心に紹
+介します．
+
+== Rubyに機能を追加する
+
+Rubyで提供されている関数を使えばRubyインタプリタに新しい機能
+を追加することができます．Rubyでは以下の機能を追加する関数が
+提供されています．
+
+* クラス，モジュール
+* メソッド，特異メソッドなど
+* 定数
+
+では順に紹介します．
+
+=== クラス/モジュール定義
+
+クラスやモジュールを定義するためには，以下の関数を使います．
 
   VALUE rb_define_class(const char *name, VALUE super)
   VALUE rb_define_module(const char *name)
 
-�����δؿ��Ͽ�����������줿���饹��⥸�塼����֤��ޤ���
-�᥽�åɤ����������ˤ������ͤ�ɬ�פʤΤǡ��ۤȤ�ɤξ��
-������ͤ��ѿ��˳�Ǽ���Ƥ���ɬ�פ�����Ǥ��礦��
+これらの関数は新しく定義されたクラスやモジュールを返します．
+メソッドや定数の定義にこれらの値が必要なので，ほとんどの場合
+は戻り値を変数に格納しておく必要があるでしょう．
 
-���饹��⥸�塼���¾�Υ��饹�������˥ͥ��Ȥ�������������
-�ϰʲ��δؿ���Ȥ��ޤ���
+クラスやモジュールを他のクラスの内部にネストして定義する時に
+は以下の関数を使います．
 
   VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
   VALUE rb_define_module_under(VALUE outer, const char *name)
 
-2.1.2 �᥽�å�/�ðۥ᥽�å����
+=== メソッド/特異メソッド定義
 
-�᥽�åɤ��ðۥ᥽�åɤ��������ˤϰʲ��δؿ���Ȥ��ޤ���
+メソッドや特異メソッドを定義するには以下の関数を使います．
 
-  void rb_define_method(VALUE klass, const char *name, 
-		        VALUE (*func)(), int argc)
+  void rb_define_method(VALUE klass, const char *name,
+                        VALUE (*func)(), int argc)
 
-  void rb_define_singleton_method(VALUE object, const char *name, 
-			          VALUE (*func)(), int argc)
+  void rb_define_singleton_method(VALUE object, const char *name,
+                                  VALUE (*func)(), int argc)
+
+
+念のため説明すると「特異メソッド」とは，その特定のオブジェク
+トに対してだけ有効なメソッドです．RubyではよくSmalltalkにお
+けるクラスメソッドとして，クラスに対する特異メソッドが使われ
+ます．
 
+これらの関数の argcという引数はCの関数へ渡される引数の数(と
+形式)を決めます．argcが0以上の時は関数に引き渡す引数の数を意
+味します．16個以上の引数は使えません(が，要りませんよね，そ
+んなに)．実際の関数には先頭の引数としてselfが与えられますの
+で，指定した数より1多い引数を持つことになります．

+argcが負の時は引数の数ではなく，形式を指定したことになります．
+argcが-1の時は引数を配列に入れて渡されます．argcが-2の時は引
+数はRubyの配列として渡されます．

+もし引数がシンボルでも文字列でもなければ、to_strメソッドで文

+Ruby 1.1からは任意のディレクトリでダイナミックライブラリを作
+ることができるようになりました．Rubyに静的にリンクする場合に
+はRubyを展開したディレクトリの下，extディレクトリの中に拡張
+ライブラリ用のディレクトリを作る必要があります．名前は適当に
+選んで構いません．
+
+== 設計する
+
+まあ，当然なんですけど，どういう機能を実現するかどうかまず設
+計する必要があります．どんなクラスをつくるか，そのクラスには
+どんなメソッドがあるか，クラスが提供する定数などについて設計
+します．
+
+== Cコードを書く
+
+拡張ライブラリ本体となるC言語のソースを書きます．C言語のソー
+スがひとつの時には「ライブラリ名.c」を選ぶと良いでしょう．C
+言語のソースが複数の場合には逆に「ライブラリ名.c」というファ
+イル名は避ける必要があります．オブジェクトファイルとモジュー
+ル生成時に中間的に生成される「ライブラリ名.o」というファイル
+とが衝突するからです．また，後述する mkmf ライブラリのいくつ
+かの関数がコンパイルを要するテストのために「conftest.c」とい
+うファイル名を使用することに注意してください．ソースファイル
+名として「conftest.c」を使用してはなりません．
+
+Rubyは拡張ライブラリをロードする時に「Init_ライブラリ名」と
+いう関数を自動的に実行します．dbmライブラリの場合「Init_dbm」
+です．この関数の中でクラス，モジュール，メソッド，定数などの
+定義を行います．dbm.cから一部引用します．
+
+  void
+  Init_dbm(void)
+  {
+      /* DBMクラスを定義する */
+      cDBM = rb_define_class("DBM", rb_cObject);
+      /* DBMはEnumerableモジュールをインクルードする */
+      rb_include_module(cDBM, rb_mEnumerable);
+  
+      /* DBMクラスのクラスメソッドopen(): 引数はCの配列で受ける */
+      rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
+  
+      /* DBMクラスのメソッドclose(): 引数はなし */
+      rb_define_method(cDBM, "close", fdbm_close, 0);
+      /* DBMクラスのメソッド[]: 引数は1個 */
+      rb_define_method(cDBM, "[]", fdbm_fetch, 1);
+
+      /* ... */
+  
+      /* DBMデータを格納するインスタンス変数名のためのID */
+      id_dbm = rb_intern("dbm");
+  }
+
+DBMライブラリはdbmのデータと対応するオブジェクトになるはずで
+すから，Cの世界のdbmをRubyの世界に取り込む必要があります．
+
+dbm.cではData_Make_Structを以下のように使っています．
+
+  struct dbmdata {
+      int  di_size;
+      DBM *di_dbm;
+  };
+  
+  
+  obj = Data_Make_Struct(klass, struct dbmdata, 0, free_dbm, dbmp);
+
+ここではdbmstruct構造体へのポインタをDataにカプセル化してい
+ます．DBM*を直接カプセル化しないのはclose()した時の処理を考
+えてのことです．
+
+Dataオブジェクトからdbmstruct構造体のポインタを取り出すため
+に以下のマクロを使っています．
+
+  #define GetDBM(obj, dbmp) {\
+      Data_Get_Struct(obj, struct dbmdata, dbmp);\
+      if (dbmp->di_dbm == 0) closed_dbm();\
+  }
+
+ちょっと複雑なマクロですが，要するにdbmdata構造体のポインタ
+の取り出しと，closeされているかどうかのチェックをまとめてい
+るだけです．
+
+DBMクラスにはたくさんメソッドがありますが，分類すると3種類の
+引数の受け方があります．ひとつは引数の数が固定のもので，例と
+してはdeleteメソッドがあります．deleteメソッドを実装している
+fdbm_delete()はこのようになっています．
+
+  static VALUE
+  fdbm_delete(VALUE obj, VALUE keystr)
+  {
+      /* ... */
+  }
+
+引数の数が固定のタイプは第1引数がself，第2引数以降がメソッド
+の引数となります．
+
+引数の数が不定のものはCの配列で受けるものとRubyの配列で受け
+るものとがあります．dbmライブラリの中で，Cの配列で受けるもの
+はDBMのクラスメソッドであるopen()です．これを実装している関
+数fdbm_s_open()はこうなっています．
+
+  static VALUE
+  fdbm_s_open(int argc, VALUE *argv, VALUE klass)
+  {
+      /* ... */
+
+      if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
+  	mode = 0666;		/* default value */
+      }
+
+      /* ... */
+  }
+
+このタイプの関数は第1引数が与えられた引数の数，第2引数が与え
+られた引数の入っている配列になります．selfは第3引数として与
+えられます．
+
+この配列で与えられた引数を解析するための関数がopen()でも使わ
+れているrb_scan_args()です．第3引数に指定したフォーマットに従
+い，第4変数以降に指定したVALUEへの参照に値を代入してくれま
+す．
+
+
+引数をRubyの配列として受け取るメソッドの例には
+Thread#initializeがあります．実装はこうです．
+
+  static VALUE
+  thread_initialize(VALUE thread, VALUE args)
+  {
+      /* ... */
+  }

-- fork_and_kill_other_threads.
-- signal list (Signal::trap, Signal::list).
-- move NameError under StandardError.
-- Integer#to_s(base)
-- Hash::new{default}
-- hash etc. should handle self referenceing array/hash
-- Array#select(n1,n2...) works like Array#indexes(n1,n2...)

-* method to retrieve non-number trailer for to_i/to_f.
-* Stream or Port, abstract superclass of IO ?
-* String#{pred,prev}, String#downto
-* optional stepsize argument for succ()
-* Ruby module -- Ruby::Version, Ruby::Interpreter
-* introduce Boolean class; super of TrueClass, FalseClass
-* synchronized method - synchronized{...}, synchronized :foo, :bar
-* Array#&, Array#| to allow duplication. ???
-* way to specify immortal (fork endurance) thread;
-* or raise ForkException to every thread but fork caller.
-* new user-defined marshal scheme. _dump(dumper), _load(restorer)
-* library to load per-user profile seeking .ruby_profile or ruby.ini file.
-* warning framework (warn, warning for Ruby level)
-* marshal should not depend on sprintf (works bad with locale).
-* ternary arg pow: a.pow(b,c) == a**b%c
-* new caller(), e.g. call_stack; needs better name.
-* pointer share mechanism similar to one in String for Array.
-* require "1.6" etc. by /usr/lib/ruby/1.6/1.6.rb ;-)

+ *  In find-minimum mode (this is a good choice for typical use case),

+ *

+ *     ary.bsearch {|x| x >= 100 } #=> nil
+ *
+ *  In find-any mode (this behaves like libc's bsearch(3)), the block
+ *  must return a number, and there must be two indices i and j
+ *  (0 <= i <= j <= ary.size) so that:
+ *
+ *  - the block returns a positive number for ary[k] if 0 <= k < i,
+ *  - the block returns zero for ary[k] if i <= k < j, and
+ *  - the block returns a negative number for ary[k] if
+ *    j <= k < ary.size.
+ *
+ *  Under this condition, this method returns any element whose index

+ *  Arrays are ordered, integer-indexed collections of any object.
+ *
+ *  Array indexing starts at 0, as in C or Java.  A negative index is assumed
+ *  to be relative to the end of the array---that is, an index of -1 indicates
+ *  the last element of the array, -2 is the next to last element in the
+ *  array, and so on.
+ *
+ *  == Creating Arrays
+ *
+ *  A new array can be created by using the literal constructor
+ *  <code>[]</code>.  Arrays can contain different types of objects.  For
+ *  example, the array below contains an Integer, a String and a Float:
+ *
+ *     ary = [1, "two", 3.0] #=> [1, "two", 3.0]
+ *
+ *  An array can also be created by explicitly calling Array.new with zero, one
+ *  (the initial size of the Array) or two arguments (the initial size and a
+ *  default object).
+ *
+ *     ary = Array.new    #=> []
+ *     Array.new(3)       #=> [nil, nil, nil]
+ *     Array.new(3, true) #=> [true, true, true]
+ *
+ *  Note that the second argument populates the array with references to the
+ *  same object.  Therefore, it is only recommended in cases when you need to
+ *  instantiate arrays with natively immutable objects such as Symbols,
+ *  numbers, true or false.
+ *
+ *  To create an array with separate objects a block can be passed instead.
+ *  This method is safe to use with mutable objects such as hashes, strings or
+ *  other arrays:
+ *
+ *     Array.new(4) { Hash.new } #=> [{}, {}, {}, {}]
+ *
+ *  This is also a quick way to build up multi-dimensional arrays:
+ *
+ *     empty_table = Array.new(3) { Array.new(3) }
+ *     #=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
+ *
+ *  An array can also be created by using the Array() method, provided by
+ *  Kernel, which tries to call #to_ary, then #to_a on its argument.
+ *
+ *	Array({:a => "a", :b => "b"}) #=> [[:a, "a"], [:b, "b"]]
+ *
+ *  == Example Usage
+ *
+ *  In addition to the methods it mixes in through the Enumerable module, the
+ *  Array class has proprietary methods for accessing, searching and otherwise
+ *  manipulating arrays.
+ *
+ *  Some of the more common ones are illustrated below.
+ *
+ *  == Accessing Elements
+ *
+ *  Elements in an array can be retrieved using the Array#[] method.  It can
+ *  take a single integer argument (a numeric index), a pair of arguments
+ *  (start and length) or a range.
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr[2]    #=> 3
+ *     arr[100]  #=> nil
+ *     arr[-3]   #=> 4
+ *     arr[2, 3] #=> [3, 4, 5]
+ *     arr[1..4] #=> [2, 3, 4, 5]
+ *
+ *  Another way to access a particular array element is by using the #at method
+ *
+ *     arr.at(0) #=> 1
+ *
+ *  The #slice method works in an identical manner to Array#[].
+ *
+ *  To raise an error for indices outside of the array bounds or else to
+ *  provide a default value when that happens, you can use #fetch.
+ *
+ *     arr = ['a', 'b', 'c', 'd', 'e', 'f']
+ *     arr.fetch(100) #=> IndexError: index 100 outside of array bounds: -6...6
+ *     arr.fetch(100, "oops") #=> "oops"
+ *
+ *  The special methods #first and #last will return the first and last
+ *  elements of an array, respectively.
+ *
+ *     arr.first #=> 1
+ *     arr.last  #=> 6
+ *
+ *  To return the first +n+ elements of an array, use #take
+ *
+ *     arr.take(3) #=> [1, 2, 3]
+ *
+ *  #drop does the opposite of #take, by returning the elements after +n+
+ *  elements have been dropped:
+ *
+ *     arr.drop(3) #=> [4, 5, 6]
+ *
+ *  == Obtaining Information about an Array
+ *
+ *  Arrays keep track of their own length at all times.  To query an array
+ *  about the number of elements it contains, use #length, #count or #size.
+ *
+ *    browsers = ['Chrome', 'Firefox', 'Safari', 'Opera', 'IE']
+ *    browsers.length #=> 5
+ *    browsers.count #=> 5
+ *
+ *  To check whether an array contains any elements at all
+ *
+ *    browsers.empty? #=> false
+ *
+ *  To check whether a particular item is included in the array
+ *
+ *    browsers.include?('Konqueror') #=> false
+ *
+ *  == Adding Items to Arrays
+ *
+ *  Items can be added to the end of an array by using either #push or #<<
+ *
+ *    arr = [1, 2, 3, 4]
+ *    arr.push(5) #=> [1, 2, 3, 4, 5]
+ *    arr << 6    #=> [1, 2, 3, 4, 5, 6]
+ *
+ *  #unshift will add a new item to the beginning of an array.
+ *
+ *     arr.unshift(0) #=> [0, 1, 2, 3, 4, 5, 6]
+ *
+ *  With #insert you can add a new element to an array at any position.
+ *
+ *     arr.insert(3, 'apple')  #=> [0, 1, 2, 'apple', 3, 4, 5, 6]
+ *
+ *  Using the #insert method, you can also insert multiple values at once:
+ *
+ *     arr.insert(3, 'orange', 'pear', 'grapefruit')
+ *     #=> [0, 1, 2, "orange", "pear", "grapefruit", "apple", 3, 4, 5, 6]
+ *
+ *  == Removing Items from an Array
+ *
+ *  The method #pop removes the last element in an array and returns it:
+ *
+ *     arr =  [1, 2, 3, 4, 5, 6]
+ *     arr.pop #=> 6
+ *     arr #=> [1, 2, 3, 4, 5]
+ *
+ *  To retrieve and at the same time remove the first item, use #shift:
+ *
+ *     arr.shift #=> 1
+ *     arr #=> [2, 3, 4, 5]
+ *
+ *  To delete an element at a particular index:
+ *
+ *     arr.delete_at(2) #=> 4
+ *     arr #=> [2, 3, 5]
+ *
+ *  To delete a particular element anywhere in an array, use #delete:
+ *
+ *     arr = [1, 2, 2, 3]
+ *     arr.delete(2) #=> [1, 3]
+ *
+ *  A useful method if you need to remove +nil+ values from an array is
+ *  #compact:
+ *
+ *     arr = ['foo', 0, nil, 'bar', 7, 'baz', nil]
+ *     arr.compact  #=> ['foo', 0, 'bar', 7, 'baz']
+ *     arr          #=> ['foo', 0, nil, 'bar', 7, 'baz', nil]
+ *     arr.compact! #=> ['foo', 0, 'bar', 7, 'baz']
+ *     arr          #=> ['foo', 0, 'bar', 7, 'baz']
+ *
+ *  Another common need is to remove duplicate elements from an array.
+ *
+ *  It has the non-destructive #uniq, and destructive method #uniq!
+ *
+ *     arr = [2, 5, 6, 556, 6, 6, 8, 9, 0, 123, 556]
+ *     arr.uniq #=> [2, 5, 6, 556, 8, 9, 0, 123]
+ *
+ *  == Iterating over Arrays
+ *
+ *  Like all classes that include the Enumerable module, Array has an each
+ *  method, which defines what elements should be iterated over and how.  In
+ *  case of Array's #each, all elements in the Array instance are yielded to
+ *  the supplied block in sequence.
+ *
+ *  Note that this operation leaves the array unchanged.
+ *
+ *     arr = [1, 2, 3, 4, 5]
+ *     arr.each { |a| print a -= 10, " " }
+ *     # prints: -9 -8 -7 -6 -5
+ *     #=> [1, 2, 3, 4, 5]
+ *
+ *  Another sometimes useful iterator is #reverse_each which will iterate over
+ *  the elements in the array in reverse order.
+ *
+ *     words = %w[rats live on no evil star]
+ *     str = ""
+ *     words.reverse_each { |word| str += "#{word.reverse} " }
+ *     str #=> "rats live on no evil star "
+ *
+ *  The #map method can be used to create a new array based on the original
+ *  array, but with the values modified by the supplied block:
+ *
+ *     arr.map { |a| 2*a }   #=> [2, 4, 6, 8, 10]
+ *     arr                   #=> [1, 2, 3, 4, 5]
+ *     arr.map! { |a| a**2 } #=> [1, 4, 9, 16, 25]
+ *     arr                   #=> [1, 4, 9, 16, 25]
+ *
+ *  == Selecting Items from an Array
+ *
+ *  Elements can be selected from an array according to criteria defined in a
+ *  block.  The selection can happen in a destructive or a non-destructive
+ *  manner.  While the destructive operations will modify the array they were
+ *  called on, the non-destructive methods usually return a new array with the
+ *  selected elements, but leave the original array unchanged.
+ *
+ *  === Non-destructive Selection
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr.select { |a| a > 3 }     #=> [4, 5, 6]
+ *     arr.reject { |a| a < 3 }     #=> [3, 4, 5, 6]
+ *     arr.drop_while { |a| a < 4 } #=> [4, 5, 6]
+ *     arr                          #=> [1, 2, 3, 4, 5, 6]
+ *
+ *  === Destructive Selection
+ *
+ *  #select! and #reject! are the corresponding destructive methods to #select
+ *  and #reject
+ *
+ *  Similar to #select vs. #reject, #delete_if and #keep_if have the exact
+ *  opposite result when supplied with the same block:
+ *
+ *     arr.delete_if { |a| a < 4 } #=> [4, 5, 6]
+ *     arr                         #=> [4, 5, 6]
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr.keep_if { |a| a < 4 } #=> [1, 2, 3]
+ *     arr                       #=> [1, 2, 3]
+ *

+Hello there, Izchak Miller was my father.  When I was younger I spent 
+many a night, hunched over the keyboard with a cup of tea, playing 
+nethack with him and my brother.  my dad was a philosopher with a strong 
+weakness for fantasy/sci fi.  I remember when he started to get involved 
+with the Nethack team- my brother's Dungeons and Dragons monster book 
+found a regular place beside my dad's desk. it's nice to see him living 
+on in the game he loved so much :-).  
+                                                                  Tamar Miller
