-		    GNU GENERAL PUBLIC LICENSE
-		     Version 1, February 1989
+Ruby is copyrighted free software by Yukihiro Matsumoto <matz@netlab.jp>.
+You can redistribute it and/or modify it under either the terms of the
+2-clause BSDL (see the file BSDL), or the conditions below:
 
- Copyright (C) 1989 Free Software Foundation, Inc.
-                    675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
+  1. You may make and give away verbatim copies of the source form of the
+     software without restriction, provided that you duplicate all of the
+     original copyright notices and associated disclaimers.
 
-			    Preamble
+  2. You may modify your copy of the software in any way, provided that
+     you do at least ONE of the following:
 
-  The license agreements of most software companies try to keep users
-at the mercy of those companies.  By contrast, our General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  The
-General Public License applies to the Free Software Foundation's
-software and to any other program whose authors commit to using it.
-You can use it for your programs, too.
+       a) place your modifications in the Public Domain or otherwise
+          make them Freely Available, such as by posting said
+	  modifications to Usenet or an equivalent medium, or by allowing
+	  the author to include your modifications in the software.
 
-  When we speak of free software, we are referring to freedom, not
-price.  Specifically, the General Public License is designed to make
-sure that you have the freedom to give away or sell copies of free
-software, that you receive source code or can get it if you want it,
-that you can change the software or use pieces of it in new free
-programs; and that you know you can do these things.
+       b) use the modified software only within your corporation or
+          organization.
 
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
+       c) give non-standard binaries non-standard names, with
+          instructions on where to get the original software distribution.
 
-  For example, if you distribute copies of a such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must tell them their rights.
+       d) make other distribution arrangements with the author.
 
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
+  3. You may distribute the software in object code or binary form,
+     provided that you do at least ONE of the following:
 
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
+       a) distribute the binaries and library files of the software,
+	  together with instructions (in the manual page or equivalent)
+	  on where to get the original distribution.
 
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+       b) accompany the distribution with the machine-readable source of
+	  the software.
 
-  0. This License Agreement applies to any program or other work which
-contains a notice placed by the copyright holder saying it may be
-distributed under the terms of this General Public License.  The
-"Program", below, refers to any such program or work, and a "work based
-on the Program" means either the Program or any work containing the
-Program or a portion of it, either verbatim or with modifications.  Each
-licensee is addressed as "you".
+       c) give non-standard binaries non-standard names, with
+          instructions on where to get the original software distribution.
 
-  1. You may copy and distribute verbatim copies of the Program's 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
-General Public License and to the absence of any warranty; and give any
-other recipients of the Program a copy of this General Public License
-along with the Program.  You may charge a fee for the physical act of
-transferring a copy.
+       d) make other distribution arrangements with the author.
 
-  2. You may modify your copy or copies of the Program or any portion of
-it, and copy and distribute such modifications under the terms of Paragraph
-1 above, provided that you also do the following:
+  4. You may modify and include the part of the software into any other
+     software (possibly commercial).  But some files in the distribution
+     are not written by the author, so that they are not under these terms.
 
-    a) cause the modified files to carry prominent notices stating that
-    you changed the files and the date of any change; and
+     For the list of those files and their copying conditions, see the
+     file LEGAL.
 
-    b) cause the whole of any work that you distribute or publish, that
-    in whole or in part contains the Program or any part thereof, either
-    with or without modifications, to be licensed at no charge to all
-    third parties under the terms of this General Public License (except
-    that you may choose to grant warranty protection to some or all
-    third parties, at your option).
+  5. The scripts and library files supplied as input to or produced as 
+     output from the software do not automatically fall under the
+     copyright of the software, but belong to whomever generated them, 
+     and may be sold commercially, and may be aggregated with this
+     software.
 
-    c) If the modified program normally reads commands interactively when
-    run, you must cause it, when started running for such interactive use
-    in the simplest and most usual way, to print or display an
-    announcement including an appropriate copyright notice and a notice
-    that there is no warranty (or else, saying that you provide a
-    warranty) and that users may redistribute the program under these
-    conditions, and telling the user how to view a copy of this General
-    Public License.
-
-    d) 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.
-
-Mere aggregation of another independent work with the Program (or its
-derivative) on a volume of a storage or distribution medium does not bring
-the other work under the scope of these terms.
-
-  3. You may copy and distribute the Program (or a portion or derivative of
-it, under Paragraph 2) in object code or executable form under the terms of
-Paragraphs 1 and 2 above provided that you also do one of the following:
-
-    a) accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of
-    Paragraphs 1 and 2 above; or,
-
-    b) accompany it with a written offer, valid for at least three
-    years, to give any third party free (except for a nominal charge
-    for the cost of distribution) a complete machine-readable copy of the
-    corresponding source code, to be distributed under the terms of
-    Paragraphs 1 and 2 above; or,
-
-    c) accompany it with the information you received as to where the
-    corresponding source code may be obtained.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form alone.)
-
-Source code for a work means the preferred form of the work for making
-modifications to it.  For an executable file, complete source code means
-all the source code for all modules it contains; but, as a special
-exception, it need not include source code for modules which are standard
-libraries that accompany the operating system on which the executable
-file runs, or for standard header files or definitions files that
-accompany that operating system.
-
-  4. You may not copy, modify, sublicense, distribute or transfer the
-Program except as expressly provided under this General Public License.
-Any attempt otherwise to copy, modify, sublicense, distribute or transfer
-the Program is void, and will automatically terminate your rights to use
-the Program under this License.  However, parties who have received
-copies, or rights to use copies, from you under this General Public
-License will not have their licenses terminated so long as such parties
-remain in full compliance.
-
-  5. By copying, distributing or modifying the Program (or any work based
-on the Program) you indicate your acceptance of this license to do so,
-and all its terms and conditions.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the original
-licensor to copy, distribute or modify the Program subject to these
-terms and conditions.  You may not impose any further restrictions on the
-recipients' exercise of the rights granted herein.
-
-  7. The Free Software Foundation may publish revised and/or new versions
-of the 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 Program
-specifies a version number of the 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 Program does not specify a version number of
-the license, you may choose any version ever published by the Free Software
-Foundation.
-
-  8. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, 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
-
-  9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  10. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to humanity, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these
-terms.
-
-  To do so, attach the following notices to the program.  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 program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 1, or (at your option)
-    any later version.
-
-    This program 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

+	  You need to choose correct stack size carefully. These values

-	* io.c (io_puts): avoid generating "\n" each time.  use RS_default
- 	  instead.
+	* 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.
+	  This feature goes to next minor (2.1?).
+	  Nobody may use this feature and there is no compatibility issue.

-Tue Apr 14 11:34:50 1998  Yukihiro Matsumoto  <matz@netlab.co.jp>
+	* 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.

+
+	* 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

+	  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

+Mon Nov 12 19:14:50 2012  Akinori MUSHA  <knu@iDaemons.org>
+
+	* configure.in (isinf, isnan): isinf() and isnan() are macros on
+	  DragonFly which cannot be found by AC_REPLACE_FUNCS().  This

+
+Mon Nov 12 15:59:38 2012  Shugo Maeda  <shugo@ruby-lang.org>

+
+Fri Nov  9 16:08:46 2012  Sokolov Yura funny-falcon  <funny.falcon@gmail.com>
+
+	* array.c: speedup Array#unshift by using space in shared array.
+	  [Feature #6638]
+	  - when array owns its shared array (ARY_SHARED_NUM == 1), and there
+	    is enough space then try unshift values directly into shared
+	    array.
+	  - when resulting array is big (~>64 items) then make it shared with
+	    enough room for future #unshifts, and then insert into shared
+	    array.
+
+	* array.c (rb_ary_splice): use shared array in rb_ary_slice.
+	  [Feature #6638]
+	  - use ary_ensure_room_for_push when rb_ary_slice used to add at the
+	    end of array, cause rb_ary_concat use rb_ary_slice.
+
+	* array.c (ary_ensure_room_for_push): make array really suitable for
+	  queue.  [Feature #6638]
+	  when array is shared (which happens after Array#shift), and
+	  ARY_SHARED_NUM == 1 (which is very often when array used as queue),
+	  then make rb_ary_push push directly into shared array.
+
+	* array.c (rb_ary_modify): steal shared array's container when
+	  ARY_SHARED_NUM == 1.  [Feature #6638]
+	  - Do not allocate new memory in rb_ary_modify when ARY_SHARED_NUM == 1
+	    and length almost same.
+	  - Store ARY_CAPA instead of RARRAY_LEN in ary_make_shared, to make
+	    it useful.
+	  - Fix rb_ary_sort_bang accordantly.

+
+Fri Nov  9 12:58:13 2012  NARUSE, Yui  <naruse@ruby-lang.org>
+
+	* string.c (rb_str_crypt): crypt(3) may return NULL.

+Fri Nov  9 12:07:06 2012  Akinori MUSHA  <knu@iDaemons.org>
+
+	* include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c
+	  (alloca): Make alloca() globally available by moving the
+	  ultimate ifdef's to ruby/ruby.h.  Gcc hides its builtin alloca()
+	  when compiling with -ansi, and linking thus fails on platforms
+	  that lack their own alloca() implementation in libc, which
+	  include OpenBSD and some ports of NetBSD.  We use alloca()
+	  everywhere including from within third party C extensions, so
+	  alloca() must be made globally available. [Bug #7307]
+
+	* addr2line.c (alloca): Replace the alloca() part with the
+	  ultimate ifdef's. [Bug #7307]

+
+Tue Oct 23 12:57:29 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_core.h, vm_insnhelper.c, vm_eval.c (OPT_CALL_CFUNC_WITHOUT_FRAME):
+	  add a new optimization and its macro `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.
+
+	* vm_insnhelper.c, vm.c: add VM_PROFILE* macros to measure behaviour
+	  of VM internals. I will extend this feature.
+
+	* vm_method.c, method.h: change parameters of the `invoker' function.
+	  Receive `func' pointer as the first parameter.

+
+Wed Oct 17 08:32:46 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* compile.c (compile_dstr_fragments): use `putobject' instead of
+	  `putstring' for all of strings used by NODE_DSTR because
+	  ruby users can not grab this string.
+	  For example, the string object of "baz" in "foo#{bar}baz"
+	  is located by `putobject' (users can not touch "baz" object
+	  directly). This change reduces GC pressure.
+	  This improvement is suggested by Aaron Patterson.

+Wed Oct 17 01:53:47 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (vm_getivar, vm_setivar): support index inline cache
+	  with rb_call_info_t to speedup `attr' getter and setter.
+	  Cached index is stored in rb_call_info_t::aux::index.
+	  `index' == 0 means not cached. `index' > 0 means cached and cached
+	  index is `index - 1'.
+
+	* insns.def ((get|set)instancevariable): use new wrapper functions
+	  vm_(get|set)instancevariable() defined in vm_insnhelper.c.
+
+	* vm_core.h (rb_call_info_t::aux): introduce new union data because

+
+Tue Oct 16 21:59:01 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* benchmark/driver.rb: some refactoring.
+	  (1) Remove `average differential'.
+	      In this benchmark driver, We should not care about `average'.
+	      We use fastest score because this score should not include
+	      any disturbances (affections of background process, etc).
+	      If you care about timing affect, I recommend `median'
+	      score with more than 5 examinations rather than simple
+	      `average' score (`average' score was affected by error scores).
+	  (2) Show log file name.
+	  (3) Change default directory from './' to driver's directory.

+	* vm_insnhelper.c (VM_CALLEE_SETUP_ARG): fix wrong condition.
+
+Tue Oct 16 06:29:18 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (vm_call_method): disable CI_SET_FASTPATH() if
+	  this method call needs splat argument because cached functions
+	  (vm_call_attrset, vm_call_ivar, vm_call_cfunc_fast_(unary|binary))
+	  do not check an arity.
+
+	* bootstraptest/test_method.rb: add a test to check an above issue.
+
+Tue Oct 16 06:15:44 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* method.h: introduce new method type VM_METHOD_TYPE_CFUNC_FAST.
+	  This method is similar to VM_METHOD_TYPE_CFUNC methods, but
+	  called cfunc without building new frame (does not push new control
+	  frame). If error is occurred in cfunc, the backtrace only shows
+	  caller frame and upper.
+	  This kind of methods can be added by rb_define_method_fast().
+	  This feature is similar to specialized instructions (opt_plus, etc),
+	  but more flexible (but a bit slower).
+
+	* class.c (rb_define_method_fast): added.
+	  Maybe it will be renamed soon.
+
+	* vm_insnhelper.c (vm_call_method): support method type
+	  VM_METHOD_TYPE_CFUNC_FAST.
+
+	* proc.c (rb_method_entry_arity): catch up new method type.
+
+	* vm_method.c (rb_add_method_cfunc_fast): added.
+
+Tue Oct 16 02:32:29 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.h (CI_SET_FASTPATH): add new parameter `enabled'.
+	  If `enable' is 0 then CI_SET_FASTPATH() doesn't work.
+	  And add new configuration option OPT_CALL_FASTPATH. If this macro
+	  was defined by 0, then CI_SET_FASTPATH() doesn't work any more.
+
+	* vm_insnhelper.c (vm_call_method): Pass `0' for `enabled' parameter
+	  of CI_SET_FASTPATH if this method is protected.
+
+Tue Oct 16 02:17:35 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_core.h (VM_CALL_*): rename VM_CALL_*_BIT
+	  to VM_CALL_* (remove `_BIT' suffix).
+	  Add comments on each macros.
+	  Remove unused macro VM_CALL_TAILRECURSION_BIT.
+
+	* compile.c, iseq.c, insns.def, vm_insnhelper.c: ditto.
+
+Mon Oct 15 22:14:44 2012  Nobuyoshi Nakada  <nobu@ruby-lang.org>
+
+	* test/ruby/envutil.rb (Test::Unit::Assertions#file_assertion):
+	  rewrite file assertions.
+
+Mon Oct 15 09:41:17 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (VM_CALLEE_SETUP_ARG): skip CI_SET_FASTPATH() if
+	  it was called from vm_yield_setup_args().
+
+Mon Oct 15 05:20:13 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.h CI_SET_FASTPATH: introduce new macro
+	  `CI_SET_FASTPATH(ci, func)'. This macro set `ci->call' as `func'.
+	  `func' (ci->call) is called at the last of `send'
+	  (and `invokesuper') instruction.
+	  `CI_SET_FASTPATH' does not set `ci->call' when the method
+	  (stored in `ci->me') is `protected'.
+
+	* vm_insnhelper.c (vm_call_method): use `CI_SET_FASTPATH'.
+	  After several checking (visibility, argc checking), the result of
+	  checking can be reused until re-definition of this method
+	  with inline method cache.
+
+	  Note that this optimization is now experimental.
+	  If you find any problem about it, please tell us.
+
+Mon Oct 15 04:51:55 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c: refactoring.
+	  - move all `call' related functions to the last of file.
+	  - make functions for respective method types in vm_call_method().
+	    (all functions have same function parameters)
+
+	* vm_core.h: add `opt_pc' field in `rb_call_info_t'
+	  as temporal variable.
+
+	* vm_eval.c (vm_call0_body): catch up above changes.
+
+Mon Oct 15 03:51:46 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* benchmark/bm_vm1_attr_ivar(_set).rb: added (for method dispatch speed).
+
+	* benchmark/bm_vm1_float_simple.rb: added (for flonum/float).
+
+Mon Oct 15 02:51:16 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_eval.c (vm_call0_body): add new function.
+	  `vm_call0()' makes call_info struct and calls `vm_call0_body()'
+	  with this struct. In near future, `vm_call0()' will be removed
+	  because all of `vm_call0()' users setup call_info struct by itself.
+
+Mon Oct 15 01:38:06 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* insns.def (send, invokesuper, invokeblock, opt_*), vm_core.h:
+	  use only a `ci' (rb_call_info_t) parameter instead of using
+	  parameters such as `op_id', 'op_argc', `blockiseq' and flag.
+	  These information are stored in rb_call_info_t at the compile
+	  time.
+	  This technique simplifies parameter passing at related
+	  function calls (~10% speedups for simple method invocation at
+	  my machine).
+	  `rb_call_info_t' also has new function pointer variable `call'.
+	  This `call' variable enables to customize method (block)
+	  invocation process for each place. However, it always call
+	  `vm_call_general()' at this changes.
+	  `rb_call_info_t' also has temporary variables for method
+	  (block) invocation.
+
+	* vm_core.h, compile.c, insns.def: introduce VM_CALL_ARGS_SKIP_SETUP
+	  VM_CALL macro.  This flag indicates that this call can skip
+	  caller_setup (block arg and splat arg).
+
+	* compile.c: catch up above changes.
+
+	* iseq.c: catch up above changes (especially for TS_CALLINFO).
+
+	* tool/instruction.rb: catch up above changes.
+
+	* vm_insnhelper.c, vm_insnhelper.h: ditto. Macros and functions
+	  parameters are changed.
+
+	* vm_eval.c (vm_call0): ditto (it will be rewritten soon).

+Sun Oct 14 12:30:44 2012  Nobuyoshi Nakada  <nobu@ruby-lang.org>

+
+	  (1) add rb_hook_list_t data structure which includes
+	      hooks, events (flag) and `need_clean' flag.
+	      If the last flag is true, then clean the hooks list.
+	      In other words, deleted hooks are contained by `hooks'.
+	      Cleanup process should run before traversing the list.
+	  (2) Change check mechanism
+	      See EXEC_EVENT_HOOK() in vm_core.h.
+	  (3) Add `raw' hooks APIs
+	      Normal hooks are guarded from exception by rb_protect().
+	      However, this protection is overhead for too simple
+	      functions which never cause exceptions.  `raw' hooks
+	      are executed without protection and faster.
+	      Now, we only provide registration APIs.  All `raw'
+	      hooks are kicked under protection (same as normal hooks).

+
+	* 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.

+
+	* vm_core.h: remove VM_FRAME_MAGIC_FINISH (finish frame type).
+	  Before this commit:
+	    `finish frame' was place holder which indicates that VM loop
+	    needs to return function.
+	    If a C method calls a Ruby methods (a method written by Ruby),
+	    then VM loop will be (re-)invoked.  When the Ruby method returns,
+	    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.
+
+	* insns.def (leave, finish): remove finish instruction.

+	* vm.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c:

+
+	* 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
+	  `root_lep' and `root_svar'.
+	  (VM_EP_PREV_EP(ep)): get previous environment pointer.  This macro

+
+Sat May 26 13:40:29 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c (RubyVM::FrameInfo): add a class to access each frame
+	  information.  You don't need to parse strings from caller().
+	  FrameInfo has the following methods:
+	    FrameInfo#name: method name, class name, etc with decorations.
+	    FrameInfo#basename: name without decorations.
+	    FrameInfo#line_no: line number.
+	    FrameInfo#filename: file name.
+	    FrameInfo#filepath: full filepath.
+	    FrameInfo#iseq: iseq if it is iseq frame (defined by ruby script)
+	    FrameInfo#to_s: return caller() method style string.
+	  RubyVM::FrameInfo.caller(n, lev) returns array of FrameInfo objects.
+	  The name "RubyVM::FrameInfo.caller" is long and ambiguous (it is
+	  confusing with Kernel::caller() method), we need to change the name
+	  before Ruby 2.0 release. Good names or comments are welcome.
+
+	* test/ruby/test_backtrace.rb: add a test for above change.
+
+Sat May 26 12:18:09 2012  Koichi Sasada  <ko1@atdot.net>

+
+	* vm.c (rb_backtrace_to_str_ary): fix to use backtrace_object().
+	  This change improve performance of caller(lev, n).
+
+	* benchmark/bm_vm3_backtrace.rb: added to check above improvement.
+	  FYI: measurement on my laptop, 1.9.3p229 needs 5.125 sec,
+	  and current trunk only needs 0.299sec.

+Sat May 26 09:54:53 2012  Martin Bosslet  <Martin.Bosslet@googlemail.com>
+
+	* ext/openssl/ossl_ssl.c: Allow disabling client-side renegotiation.
+	* test/openssl/test_ssl.rb: Simple tests for this.
+
+	  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.
+
+Fri May 25 23:38:58 2012  Martin Bosslet  <Martin.Bosslet@googlemail.com>
+
+	* test/openssl/test_ssl.rb: Clarify the intention of errors to be
+	  expected. Two errors are possible when connection is refused due
+	  to a protocol version that was explicitly disallowed,
+	  OpenSSL::SSL::SSLError or Errno::ECONNRESET, depending on the
+	  OpenSSL version in use.
+
+Fri May 25 22:19:40 2012  Martin Bosslet  <Martin.Bosslet@googlemail.com>
+
+	* ext/openssl/ossl_ssl.c: Revert r35583

+
+Fri May 25 19:51:36 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_eval.c (rb_f_caller): caller() method accepts second optional
+	  argument `n' which specify how many frames should return.
+	  For example, `caller(0, 1)' returns only one frame information
+	  which calls caller() method.  If there are less than n frame
+	  information, then all frame information are returned.  If n is 0,
+	  then always return [].
+	  This fix is part of [ruby-dev:42345] [Ruby 1.9-Feature#3917].
+	  However, performance and features are not enough.
+	  RDoc is also not available.
+
+	* test/ruby/test_backtrace.rb: add a test for above.
+
+Fri May 25 17:05:07 2012  Koichi Sasada  <ko1@atdot.net>
+

+
+Fri May 25 10:52:52 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c: refactoring backtrace related functions.
+	  (1) unify similar functions (rb_backtrace_each() and
+	      backtrace_object()).  backtrace_each() is a unified function.
+	      variation:
+	      a) backtrace_object(): create backtrace object.
+	      b) vm_backtrace_str_ary(): create bt as an array of string.
+	      c) vm_backtrace_print(): print backtrace to specified file.
+	      d) rb_backtrace_print_as_bugreport(): print backtrace on
+	                                            bugreport style.
+	  (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).
+
+	* vm_core.h, vm_dump.c, vm_eval.c: ditto.
+
+	* vm.c (backtrace_object(), vm_backtrace_str_ary()): fix to return a
+	  correct size of caller(lev) array.
+	  Let n be a "caller(0).size" then ln as caller(lev).size should be
+	  (n - lev).  However, the previous implementation returns a wrong
+	  size array (ln > n - lev).  [ruby-dev:45673]
+
+	* test/ruby/test_backtrace.rb: add tests for backtrace.
+
+Fri May 25 08:51:39 2012  Eric Hodel  <drbrain@segment7.net>

+	  for last commit.
+
+	* error.c, eval_error.c: change for above.
+
+Thu May 24 14:30:13 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c: add RubyVM::Backtrace object (btobj).
+	  Backtrace information contains an array consists of location
+	  information for each frames by string.
+	  RubyVM::Backtrace object is lightweight backtrace information,
+	  which contains complete information to generate traditional style
+	  backtrace (an array of strings) with faster generation.
+	  If someone accesses to backtrace information via
+	  Exception#backtrace, then convert a RubyVM::Backtrace object to
+	  traditional style backtrace.
+	  This change causes incompatibility on marshal dumped binary
+	  of Exception.  If you have any trouble on it, please tell us
+	  before Ruby 2.0 release.
+	  Note that RubyVM::Backtrace object should not expose Ruby level.
+
+	* error.c, eval.c, vm_eval.c: ditto.
+
+	* internal.h: ditto.
+
+	* eval_error.c: fix to skip "set_backtrace" method invocation in
+	  creating an exception object if it call a normal set_backtrace
+	  method (defined by core).
+
+	* test/ruby/test_settracefunc.rb: fix for above change.
+
+	* vm_method.c (rb_method_defined_by): added.  This function
+	  checks that the given object responds with the given method
+	  by the given cfunc.
+
+	* benchmark/bm_vm2_raise1.rb, benchmark/bm_vm2_raise2.rb:
+	  add to measure exception creation speed. raise1 create
+	  exception objects from shallow stack frame.  raise2 create
+	  exception objects from deep stack frame.

+
+	* win32/win32.c (finish_overlapped_socket, overlapped_socket_io):

+	  of net/ftp.

+
+	  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.

+
+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

+
+	* 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 GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, 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 or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+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 give any other recipients of the Program a copy of this License
+along with the Program.
+
+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 Program or any portion
+of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+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 Program, 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 Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) 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; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, 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 executable.  However, as a
+special exception, the source code 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.
+
+If distribution of executable or 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 counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program 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.
+
+  5. 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 Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program 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 to
+this License.
+
+  7. 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 Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program 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 Program.
+
+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.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program 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.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the 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 Program
+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 Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, 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
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), 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 Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  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 program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program 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 General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+    A C-program for MT19937, with initialization improved 2002/2/10.
+    Coded by Takuji Nishimura and Makoto Matsumoto.
+    This is a faster version by taking Shawn Cokus's optimization,
+    Matthe Bellew's simplification, Isaku Wada's real version.
+
+    Before using, initialize the state by using init_genrand(seed) 
+    or init_by_array(init_key, key_length).

+= NEWS for Ruby 2.0.0
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 1.9.3 release
+
+=== C API updates
+* NUM2SHORT() and NUM2USHORT() added. They are similar to NUM2INT, but short.

+=== Library updates (outstanding ones only)
+
+* builtin classes
+
+  * Array
+    * added method:
+      * added Array#bsearch for binary search.
+    * incompatible changes:
+      * random parameter of Array#shuffle! and Array#sample now
+        will be called with one argument, maximum value.
+      * when given Range arguments, Array#values_at now returns nil for each
+        value that is out-of-range.
+
+  * Enumerable
+    * added method:
+      * added Enumerable#lazy method for lazy enumeration.
+
+  * Enumerator
+    * added method:
+      * added Enumerator#size for lazy size evaluation.
+    * extended method:
+      * Enumerator.new accept an argument for lazy size evaluation.
+
+  * ENV
+    * aliased method:
+      * ENV.to_h is a new alias for ENV.to_hash
+
+  * Fiber
+    * incompatible changes:
+      * Fiber#resume cannot resume a fiber which invokes "Fiber#transfer".
+
+  * File
+    * extended method:
+      * File.fnmatch? now expands braces in the pattern if
+        File::FNM_EXTGLOB option is given.
+
+  * GC
+    * improvements:
+      * introduced the bitmap marking which suppresses to copy a memory page
+        with Copy-on-Write.
+      * introduced the non-recursive marking which avoids unexpected stack overflow.
+
+  * GC::Profiler
+    * added method:
+      * added GC::Profiler.raw_data which returns raw profile data for GC.
+
+  * Hash
+    * added method:
+      * added Hash#to_h as explicit conversion method, like Array#to_a.
+    * extended method:
+      * Hash#default_proc= can be passed nil to clear the default proc.
+
+  * IO
+    * deprecated methods:
+      * IO#lines, #bytes, #chars and #codepoints are deprecated.
+
+  * Kernel
+    * added method:
+      * added Kernel#Hash conversion method like Array() or Float().
+      * added Kernel#__dir__ which returns a current dirname.
+      * added Kernel#caller_locations which returns an array of
+        frame information objects.
+    * extended method:
+      * Kernel#warn accepts multiple args in like puts.
+      * Kernel#caller accepts second optional argument `n' which specify
+        required caller size.
+      * Kernel#to_enum and enum_for accept a block for lazy size evaluation.
+    * incompatible changes:
+      * 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#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 {}
+
+  * 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 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#backtrace_locations which returns similar information of
+        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 returned encoding defaults to US-ASCII but automatically
+        transcodes to Encoding.default_internal if it is set.
+
+  * 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]
+
+* 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.
+
+* iconv
+  * Iconv has been removed. Use String#encode instead.
+
+* io/wait
+  * new features:
+    * added IO#wait_writable method.
+    * added IO#wait_readable method as alias of IO#wait.
+
+* 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.
+
+    See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a 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 2.0.0.preview2
+
+    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.
+
+* stringio
+  * deprecated methods:
+    * StringIO#lines, #bytes, #chars and #codepoints are deprecated.
+
+* 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.
+
+* 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.
+
+* yaml
+  * Syck has been removed.  YAML now completely depends on libyaml being
+    installed.
+
+* 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.
+
+=== Language changes
+
+  * Added %i and %I for symbol list creation (similar to %w and %W).
+
+  * Default source encoding is changed to UTF-8. (was US-ASCII)
+
+=== Compatibility issues (excluding feature bug fixes)
+
+  * Array#values_at
+
+    See above.
+
+  * String#lines
+  * String#chars
+  * String#codepoints
+  * String#bytes
+
+    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#codepoints
+  * 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.
+
+  * 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.
+
+  * Dir.mktmpdir in lib/tmpdir.rb
+
+    See above.
+
+  * OpenStruct new methods can conflict with custom attributes named
+    "each_pair", "eql?", "hash" or "to_h".
+
+  * Thread#join, Thread#value
+
+    See above.
+
+  * Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep
+
+    See above.

+= What's Ruby
 
 Ruby is the interpreted scripting language for quick and
 easy object-oriented programming.  It has many features to
 process text files and to do system management tasks (as in
 Perl).  It is simple, straight-forward, and extensible.

+The Ruby distribution files can be found in the following FTP site:
 
-This is what you need to do to compile and install Ruby:
+ftp://ftp.ruby-lang.org/pub/ruby/
 
-  1. Run ./configure, which will generate config.h and Makefile.
+The trunk of the Ruby source tree can be checked out with the
+following command:
 
-  2. Edit defines.h if you need.  Probably this step will not need.
+  $ svn co http://svn.ruby-lang.org/repos/ruby/trunk/ ruby
 
-  3. Remove comment mark(#) before the module names from ext/Setup (or
-     add module names if not present), if you want to link modules
-     statically.
+Or if you are using git then use following command:
 
-     If you don't want to compile non static extension modules
-     (probably on architectures which does not allow dynamic loading),
-     remove comment mark from the line "#option nodynamic" in
-     ext/Setup.
+  $ git clone git://github.com/ruby/ruby.git
 
-  4. Run make.
+There are some other branches under development.  Try the following
+command and see the list of branches:
 
-  5. Optionally, run 'make test' to check whether the compiled Ruby
-     interpreter works well.  If you see the message "test succeeded",
-     your ruby works as it should (hopefully).
+  $ svn ls http://svn.ruby-lang.org/repos/ruby/branches/
 
-  6. Run 'make install'
+Or if you are using git then use following command:
 
-     You may have to be a super user to install ruby.
+  $ git ls-remote git://github.com/ruby/ruby.git

 In C, variables have types and data do not have types.  In contrast,
-Ruby variables do not have static type and data themselves have
-types.  So, data need to be converted across the languages.
-
-Data in Ruby represented C type `VALUE'.  Each VALUE data have its
-data-type.
-
-To retrieve an C data from the VALUE, you need to:
-
- (1) Identify VALUE's data type
- (2) Convert VALUE into C data
-
-Converting to wrong data type may cause serious promblems.
-
-
-1.1 Data-types
-
-Ruby interpreter has data-types as below:
-
-	T_NIL		nil
-	T_OBJECT	ordinaly object
-	T_CLASS		class
-	T_MODULE	module
-	T_FLOAT		floating point number
-	T_STRING	string
-	T_REGEXP	regular expression
-	T_ARRAY		array
-	T_FIXNUM	Fixnum(31bit integer)
-	T_HASH		assosiative array
-	T_STRUCT	(Ruby) structure
-	T_BIGNUM	multi precision integer
-	T_TRUE		true
-	T_FALSE		false
-	T_DATA		data
-
-Otherwise, there are several other types used internally:
-
-	T_ICLASS
-	T_MATCH
-	T_VARMAP
-	T_SCOPE
-	T_NODE
+Ruby variables do not have a static type, and data themselves have
+types, so data will need to be converted between the languages.
+
+Data in Ruby are represented by the C type `VALUE'.  Each VALUE data
+has its data-type.
+
+To retrieve C data from a VALUE, you need to:
+
+1. Identify the VALUE's data type
+2. Convert the VALUE into C data
+
+Converting to the wrong data type may cause serious problems.
+
+== Data-Types
+
+The Ruby interpreter has the following data types:
+
+T_NIL       :: nil
+T_OBJECT    :: ordinary object
+T_CLASS     :: class
+T_MODULE    :: module
+T_FLOAT     :: floating point number
+T_STRING    :: string
+T_REGEXP    :: regular expression
+T_ARRAY     :: array
+T_HASH      :: associative array
+T_STRUCT    :: (Ruby) structure
+T_BIGNUM    :: multi precision integer
+T_FIXNUM    :: Fixnum(31bit or 63bit integer)
+T_COMPLEX   :: complex number
+T_RATIONAL  :: rational number
+T_FILE      :: IO
+T_TRUE      :: true
+T_FALSE     :: false
+T_DATA      :: data
+T_SYMBOL    :: symbol
+
+In addition, there are several other types used internally:
+
+T_ICLASS    :: included module
+T_MATCH     :: MatchData object
+T_UNDEF     :: undefined
+T_NODE      :: syntax tree node
+T_ZOMBIE    :: object awaiting finalization
 
 Most of the types are represented by C structures.

-1.3 Convert VALUE into C data
+== Convert VALUE into C Data
+
+The data for type T_NIL, T_FALSE, T_TRUE are nil, false, true
+respectively.  They are singletons for the data type.
+The equivalent C constants are: Qnil, Qfalse, Qtrue.
+Note that Qfalse is false in C also (i.e. 0), but not Qnil.
+
+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
+argument, to change the value of var in place.
+
+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
+for T_ARRAY etc. The VALUE of the type which has the corresponding
+structure can be cast to retrieve the pointer to the struct.  The
+casting macro will be of the form RXXXX for each data type; for
+instance, RARRAY(obj).  See "ruby.h".
+
+There are some accessing macros for structure members, for example
+`RSTRING_LEN(str)' to get the size of the Ruby String object.  The
+allocated region can be accessed by `RSTRING_PTR(str)'.  For arrays,
+use `RARRAY_LEN(ary)' and `RARRAY_PTR(ary)' respectively.
+
+Notice: Do not change the value of the structure directly, unless you
+are responsible for the result.  This ends up being the cause of
+interesting bugs.
+
+== Convert C Data into VALUE
+
+To convert C data to Ruby values:
+
+FIXNUM ::
+
+  left shift 1 bit, and turn on LSB.
+
+Other pointer values::
+
+  cast to VALUE.
+
+You can determine whether a VALUE is pointer or not by checking its LSB.
+
+Notice Ruby does not allow arbitrary pointer values to be a VALUE.  They
+should be pointers to the structures which Ruby knows about.  The known
+structures are defined in <ruby.h>.

+= Extending Ruby with C
+
+== Adding New Features to Ruby
+
+You can add new features (classes, methods, etc.) to the Ruby
+interpreter.  Ruby provides APIs for defining the following things:
+
+* Classes, Modules
+* Methods, Singleton Methods
+* Constants
+
+=== Class and Module Definition
+
+To define a class or module, use the functions below:
+
+  VALUE rb_define_class(const char *name, VALUE super)
+  VALUE rb_define_module(const char *name)
+
+These functions return the newly created class or module.  You may
+want to save this reference into a variable to use later.
+
+To define nested classes or modules, use the functions below:
+
+  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
+  VALUE rb_define_module_under(VALUE outer, const char *name)
+
+=== Method and Singleton Method Definition
+
+To define methods or singleton methods, use these functions:
+
+  void rb_define_method(VALUE klass, const char *name,
 		        VALUE (*func)(), int argc)
 
-  void rb_define_singleton_method(VALUE object, char *name, 
-			         VALUE (*func)(), int argc)
+  void rb_define_singleton_method(VALUE object, const char *name,
+			          VALUE (*func)(), int argc)
 
+The `argc' represents the number of the arguments to the C function,
+which must be less than 17.  But I doubt you'll need that many.

+the arguments.

-�᥽�åɤ��������ؿ��Ϥ⤦��Ĥ���ޤ����ҤȤĤ�private��

+where argc is the actual number of arguments, argv is the C array of
+the arguments, and obj is the receiver.
 
-  void rb_define_private_method(VALUE class, char *name, 
-			        VALUE (*func)(), int argc)
+If argc is -2, the arguments are passed in a Ruby array. The function
+will be called like:
+
+  VALUE func(VALUE obj, VALUE args)
+
+where obj is the receiver, and args is the Ruby array containing
+actual arguments.
+
+There are some more functions to define methods. One takes an ID
+as the name of method to be defined. See also ID or Symbol below.
+
+  void rb_define_method_id(VALUE klass, ID name,
+                           VALUE (*func)(ANYARGS), int argc)
+
+There are two functions to define private/protected methods:
 
-private�᥽�åɤȤϴؿ������Ǥ����ƤӽФ����Ȥν���ʤ��᥽��
-�ɤǤ���
+  void rb_define_private_method(VALUE klass, const char *name,

-�⤢���ΤǤ�����򤢤����Math�⥸�塼���sqrt()�ʤɤ�����
-���ޤ������Υ᥽�åɤ�
+At last, rb_define_module_function defines a module functions,
+which are private AND singleton methods of the module.
+For example, sqrt is the module function defined in Math module.
+It can be called in the following way:
 
   Math.sqrt(4)
 
-�Ȥ��������Ǥ�
+or
 
   include Math
   sqrt(4)
 
-�Ȥ��������Ǥ�Ȥ��ޤ����⥸�塼��ؿ����������ؿ��ϰʲ���
-�̤�Ǥ���
+To define module functions, use:
 
-  void rb_define_module_function(VALUE module, char *name, 
+  void rb_define_module_function(VALUE module, const char *name,
 				 VALUE (*func)(), int argc)
 
-�ؿ�Ū�᥽�å�(Kernel�⥸�塼���privaet method)��������뤿
-��δؿ��ϰʲ����̤�Ǥ���
+In addition, function-like methods, which are private methods defined
+in the Kernel module, can be defined using:
+
+  void rb_define_global_function(const char *name, VALUE (*func)(), int argc)
+
+To define an alias for the method,
+
+  void rb_define_alias(VALUE module, const char* new, const char* old);
+
+To define a reader/writer for an attribute,
+
+  void rb_define_attr(VALUE klass, const char *name, int read, int write)
 
-  void rb_define_global_function(char *name, VALUE (*func)(), int argc)
+To define and undefine the `allocate' class method,
 
+  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
+  void rb_undef_alloc_func(VALUE klass);
 
-2.1.3 Constant definition
+func has to take the klass as the argument and return a newly
+allocated instance.  This instance should be as empty as possible,
+without any expensive (including external) resources.

+=== Evaluate Ruby Programs in a String
 
-2.2.1 Ruby�Υץ�������eval����
+The easiest way to use Ruby's functionality from a C program is to
+evaluate the string as Ruby program.  This function will do the job:
 
-C����Ruby�ε�ǽ��ƤӽФ���äȤ��ñ����ˡ�Ȥ��ơ�ʸ�����
-Ϳ����줿Ruby�Υץ�������ɾ������ؿ�������ޤ���
+  VALUE rb_eval_string(const char *str)
 
-  VALUE rb_eval_string(char *str)
+Evaluation is done under the current context, thus current local variables
+of the innermost method (which is defined by Ruby) can be accessed.
 
-����ɾ���ϸ��ߤδĶ��ǹԤ��ޤ����Ĥޤꡤ���ߤΥ��������ѿ�
-�ʤɤ�����Ѥ��ޤ���
+Note that the evaluation can raise an exception. There is a safer
+function:
 
-2.2.2 ID or Symbol
+  VALUE rb_eval_string_protect(const char *str, int *state)
 
-C����ʸ������ͳ������Ruby�Υ᥽�åɤ�ƤӽФ����Ȥ�Ǥ���
-�����������ˡ�Ruby���󥿥ץ꥿��ǥ᥽�åɤ��ѿ�̾����ꤹ��
-���˻Ȥ��Ƥ���ID�ˤĤ����������Ƥ����ޤ��礦��
+It returns nil when an error occur. Moreover, *state is zero if str was
+successfully evaluated, or nonzero otherwise.
 
-ID�Ȥ��ѿ�̾���᥽�å�̾��ɽ�������Ǥ���Ruby����Ǥ�
+=== ID or Symbol
 
- :���̻�
+You can invoke methods directly, without parsing the string.  First I
+need to explain about ID.  ID is the integer number to represent
+Ruby's identifiers such as variable names.  The Ruby data type
+corresponding to ID is Symbol.  It can be accessed from Ruby in the
+form:
 
-�ǥ��������Ǥ��ޤ���C���餳�����������뤿��ˤϴؿ�
+  :Identifier
 
-  rb_intern(char *name)
+or
 
-��Ȥ��ޤ����ޤ���ʸ���α黻�ҤϤ���ʸ�������ɤ����Τޤޥ���
-�ܥ�ˤʤäƤ��ޤ���
+  :"any kind of string"
 
-2.2.3 Invoke Ruby method from C
+You can get the ID value from a string within C code by using
 
-C����ʸ������ͳ������Ruby�Υ᥽�åɤ�ƤӽФ�����ˤϰʲ�
-�δؿ���Ȥ��ޤ���
+  rb_intern(const char *name)
+  rb_intern_str(VALUE name)
+
+You can retrieve ID from Ruby object (Symbol or String) given as an
+argument by using
+
+  rb_to_id(VALUE symbol)
+  rb_check_id(volatile VALUE *name)
+  rb_check_id_cstr(const char *name, long len, rb_encoding *enc)
+
+These functions try to convert the argument to a String if it was not
+a Symbol nor a String.  The second function stores the converted
+result into *name, and returns 0 if the string is not a known symbol.
+After this function returned a non-zero value, *name is always a
+Symbol or a String, otherwise it is a String if the result is 0.
+The third function takes NUL-terminated C string, not Ruby VALUE.
+
+You can convert C ID to Ruby Symbol by using
+
+  VALUE ID2SYM(ID id)
+
+and to convert Ruby Symbol object to ID, use
+
+  ID SYM2ID(VALUE symbol)
+
+=== Invoke Ruby Method from C
+
+To invoke methods directly, you can use the function below
 
   VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
 
-���δؿ��ϥ��֥�������recv��mid�ǻ��ꤵ���᥽�åɤ�Ƥӽ�

-(2) create MANIFEST file
+You need to write C code for your extension library.  If your library
+has only one source file, choosing ``LIBRARY.c'' as a file name is
+preferred.  On the other hand, in case your library has multiple source
+files, avoid choosing ``LIBRARY.c'' for a file name.  It may conflict
+with an intermediate file ``LIBRARY.o'' on some platforms.
+Note that some functions in mkmf library described below generate
+a file ``conftest.c'' for checking with compilation.  You shouldn't
+choose ``conftest.c'' as a name of a source file.
 
-  % cd ext/dbm
-  % touch MANIFEST
+Ruby will execute the initializing function named ``Init_LIBRARY'' in

+      /* DBM instance method close(): no args */
+      rb_define_method(cDBM, "close", fdbm_close, 0);
+      /* DBM instance method []: 1 argument */
+      rb_define_method(cDBM, "[]", fdbm_fetch, 1);
+
+      /* ... */
+
+      /* ID for a instance variable to store DBM data */
+      id_dbm = rb_intern("dbm");
+  }
+
+The dbm extension wraps the dbm struct in the C environment using
+Data_Make_Struct.
+
+  struct dbmdata {
+      int  di_size;
+      DBM *di_dbm;
+  };
+
+  obj = Data_Make_Struct(klass, struct dbmdata, 0, free_dbm, dbmp);
+
+This code wraps the dbmdata structure into a Ruby object.  We avoid
+wrapping DBM* directly, because we want to cache size information.
+
+To retrieve the dbmdata structure from a Ruby object, we define the
+following macro:
+
+  #define GetDBM(obj, dbmp) {\
+      Data_Get_Struct(obj, struct dbmdata, dbmp);\
+      if (dbmp->di_dbm == 0) closed_dbm();\
+  }
 
-(3) design the library
+This sort of complicated macro does the retrieving and close checking for
+the DBM.

+There are three kinds of way to receive method arguments.  First,
+methods with a fixed number of arguments receive arguments like this:
+
+  static VALUE
+  fdbm_delete(VALUE obj, VALUE keystr)
+  {
+        /* ... */
+  }
+
+The first argument of the C function is the self, the rest are the
+arguments to the method.
+
+Second, methods with an arbitrary number of arguments receive
+arguments like this:
+
+  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 */
+      }
+      /* ... */
+  }
+
+The first argument is the number of method arguments, the second
+argument is the C array of the method arguments, and the third
+argument is the receiver of the method.
+
+You can use the function rb_scan_args() to check and retrieve the
+arguments.  The third argument is a string that specifies how to
+capture method arguments and assign them to the following VALUE
+references.
+
+
+The following is an example of a method that takes arguments by Ruby's
+array:
+
+  static VALUE
+  thread_initialize(VALUE thread, VALUE args)
+  {
+      /* ... */
+  }
+
+The first argument is the receiver, the second one is the Ruby array
+which contains the arguments to the method.
+
+*Notice*: GC should know about global variables which refer to Ruby's objects,
+but are not exported to the Ruby world.  You need to protect them by
 
   void rb_global_variable(VALUE *var)

+
+== Types
+
+VALUE ::
+
+  The type for the Ruby object.  Actual structures are defined in ruby.h,
+  such as struct RString, etc.  To refer the values in structures, use
+  casting macros like RSTRING(obj).
+
+== Variables and Constants
+
+Qnil::
+  nil object
+
+Qtrue::
+  true object (default true value)
+
+Qfalse::
+  false object
+
+== C Pointer Wrapping
+
+Data_Wrap_Struct(VALUE klass, void (*mark)(), void (*free)(), void *sval) ::
+
+  Wrap a C pointer into a Ruby object.  If object has references to other
+  Ruby objects, they should be marked by using the mark function during
+  the GC process.  Otherwise, mark should be 0.  When this object is no
+  longer referred by anywhere, the pointer will be discarded by free
+  function.
+
+Data_Make_Struct(klass, type, mark, free, sval) ::
+
+  This macro allocates memory using malloc(), assigns it to the variable
+  sval, and returns the DATA encapsulating the pointer to memory region.
+
+Data_Get_Struct(data, type, sval) ::
+
+  This macro retrieves the pointer value from DATA, and assigns it to
+  the variable sval.
+
+== Checking Data Types
+
+TYPE(value) ::
+
+  Internal type (T_NIL, T_FIXNUM, etc.)
+
+FIXNUM_P(value) ::
+
+  Is +value+ a Fixnum?
+
+NIL_P(value) ::
+
+  Is +value+ nil?
+
+void Check_Type(VALUE value, int type) ::
+
+  Ensures +value+ is of the given internal +type+ or raises a TypeError
+
+SaveStringValue(value) ::
+
+  Checks that +value+ is a String and is not tainted
+
+== Data Type Conversion
+
+FIX2INT(value), INT2FIX(i) ::
+
+  Fixnum <-> integer
+
+FIX2LONG(value), LONG2FIX(l) ::
+
+  Fixnum <-> long
+
+NUM2INT(value), INT2NUM(i) ::
+
+  Numeric <-> integer
+
+NUM2UINT(value), UINT2NUM(ui) ::
+
+  Numeric <-> unsigned integer
+
+NUM2LONG(value), LONG2NUM(l) ::
+
+  Numeric <-> long
+
+NUM2ULONG(value), ULONG2NUM(ul) ::
+
+  Numeric <-> unsigned long
+
+NUM2LL(value), LL2NUM(ll) ::
+
+  Numeric <-> long long
+
+NUM2ULL(value), ULL2NUM(ull) ::
+
+  Numeric <-> unsigned long long
+
+NUM2OFFT(value), OFFT2NUM(off) ::
+
+  Numeric <-> off_t
+
+NUM2SIZET(value), SIZET2NUM(size) ::
+
+  Numeric <-> size_t
+
+NUM2SSIZET(value), SSIZET2NUM(ssize) ::
+
+  Numeric <-> ssize_t
+
+NUM2DBL(value) ::
+
+  Numeric -> double
+
+rb_float_new(f) ::
+
+  double -> Float
+
+StringValue(value) ::
+
+  Object with #to_str -> String
+
+StringValuePtr(value) ::
+
+  Object with #to_str -> pointer to String data
+
+StringValueCStr(value) ::
+
+  Object with #to_str -> pointer to String data without NULL bytes
+
+rb_str_new2(s) ::
+
+  char * -> String
+
+== Defining Class and Module
+
+VALUE rb_define_class(const char *name, VALUE super) ::
+
+  Defines a new Ruby class as a subclass of super.
+
+VALUE rb_define_class_under(VALUE module, const char *name, VALUE super) ::
+
+  Creates a new Ruby class as a subclass of super, under the module's
+  namespace.
+
+VALUE rb_define_module(const char *name) ::
+
+  Defines a new Ruby module.
+
+VALUE rb_define_module_under(VALUE module, const char *name) ::
+
+  Defines a new Ruby module under the module's namespace.
+
+void rb_include_module(VALUE klass, VALUE module) ::
+
+  Includes module into class.  If class already includes it, just ignored.
+
+void rb_extend_object(VALUE object, VALUE module) ::
+
+  Extend the object with the module's attributes.
+
+== Defining Global Variables
+
+void rb_define_variable(const char *name, VALUE *var) ::
+
+  Defines a global variable which is shared between C and Ruby.  If name
+  contains a character which is not allowed to be part of the symbol,
+  it can't be seen from Ruby programs.
+

+Rubyの拡張ライブラリの作り方を説明します．
+
+= 基礎知識
+
+Cの変数には型があり，データには型がありません．ですから，た
+とえばポインタをintの変数に代入すると，その値は整数として取
+り扱われます．逆にRubyの変数には型がなく，データに型がありま
+す．この違いのため，CとRubyは相互に変換しなければ，お互いの
+データをアクセスできません．
+
+RubyのデータはVALUEというCの型で表現されます．VALUE型のデー
+タはそのデータタイプを自分で知っています．このデータタイプと
+いうのはデータ(オブジェクト)の実際の構造を意味していて，Ruby
+のクラスとはまた違ったものです．
+
+VALUEからCにとって意味のあるデータを取り出すためには
+
+1. VALUEのデータタイプを知る
+2. VALUEをCのデータに変換する
+
+の両方が必要です．(1)を忘れると間違ったデータの変換が行われ
+て，最悪プログラムがcore dumpします．
+
+== データタイプ
+
+Rubyにはユーザが使う可能性のある以下のタイプがあります．
+
+T_NIL      :: nil
+T_OBJECT   :: 通常のオブジェクト
+T_CLASS    :: クラス
+T_MODULE   :: モジュール
+T_FLOAT    :: 浮動小数点数
+T_STRING   :: 文字列
+T_REGEXP   :: 正規表現
+T_ARRAY    :: 配列
+T_HASH     :: 連想配列
+T_STRUCT   :: (Rubyの)構造体
+T_BIGNUM   :: 多倍長整数
+T_FIXNUM   :: Fixnum(31bitまたは63bit長整数)
+T_COMPLEX  :: 複素数
+T_RATIONAL :: 有理数
+T_FILE     :: 入出力
+T_TRUE     :: 真
+T_FALSE    :: 偽
+T_DATA     :: データ
+T_SYMBOL   :: シンボル
+
+その他に内部で利用されている以下のタイプがあります．
+
+  T_ICLASS
+  T_MATCH
+  T_UNDEF
+  T_NODE
+  T_ZOMBIE
+
+ほとんどのタイプはCの構造体で実装されています．
+
+== VALUEのデータタイプをチェックする
+
+ruby.hではTYPE()というマクロが定義されていて，VALUEのデータ
+タイプを知ることが出来ます．TYPE()マクロは上で紹介したT_XXXX
+の形式の定数を返します．VALUEのデータタイプに応じて処理する
+場合には，TYPE()の値で分岐することになります．
+
+  switch (TYPE(obj)) {
+    case T_FIXNUM:
+      /* FIXNUMの処理 */
+      break;
+    case T_STRING:
+      /* 文字列の処理 */
+      break;
+    case T_ARRAY:
+      /* 配列の処理 */
+      break;
+    default:
+      /* 例外を発生させる */
+      rb_raise(rb_eTypeError, "not valid value");
+      break;
+  }
+
+それとデータタイプをチェックして，正しくなければ例外を発生す
+る関数が用意されています．
+
+  void Check_Type(VALUE value, int type)
+
+この関数はvalueがtypeで無ければ，例外を発生させます．引数と
+して与えられたVALUEのデータタイプが正しいかどうかチェックす
+るためには，この関数を使います．
+
+FIXNUMとNILに関してはより高速な判別マクロが用意されています．
+
+  FIXNUM_P(obj)
+  NIL_P(obj)
+
+== VALUEをCのデータに変換する
+
+データタイプがT_NIL，T_FALSE，T_TRUEである時，データはそれぞ
+れnil，false，trueです．このデータタイプのオブジェクトはひと
+つずつしか存在しません．
+
+データタイプがT_FIXNUMの時，これは31bitまたは63bitのサイズを
+持つ整数です．longのサイズが32bitのプラットフォームであれば
+31bitに，longのサイズが64bitのプラットフォームであれば63bit
+になります. FIXNUM を C の整数に変換するためにはマクロ
+「FIX2INT()」または「FIX2LONG()」を使います．これらのマクロ
+を使用する際には事前にデータタイプがFIXNUMであることを確認す
+る必要がありますが，比較的高速に変換を行うことができます．ま
+た，「FIX2LONG()」は例外を発生しませんが，「FIX2INT()」は変
+換結果がintのサイズに収まらない場合には例外を発生します．
+それから，FIXNUMに限らずRubyのデータを整数に変換する
+「NUM2INT()」および「NUM2LONG()」というマクロがあります．こ
+れらのマクロはマクロはデータタイプのチェック無しで使えます
+(整数に変換できない場合には例外が発生する)．同様にチェック無
+で使える変換マクロはdoubleを取り出す「NUM2DBL()」があります．
+
+char* を取り出す場合， StringValue() と StringValuePtr()
+を使います．
+StringValue(var) は var が String
+であれば何もせず，そうでなければ var を var.to_str() の結果
+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．
+
+それ以外のデータタイプは対応するCの構造体があります．対応す
+る構造体のあるVALUEはそのままキャスト(型変換)すれば構造体の
+ポインタに変換できます．
+
+構造体は「struct RXxxxx」という名前でruby.hで定義されていま
+す．例えば文字列は「struct RString」です．実際に使う可能性が
+あるのは文字列と配列くらいだと思います．
+
+ruby.hでは構造体へキャストするマクロも「RXXXXX()」(全部大文
+字にしたもの)という名前で提供されています(例: RSTRING())．
+
+構造体からデータを取り出すマクロが提供されています．文字列
+strの長さを得るためには「RSTRING_LEN(str)」とし，文字列strを
+char*として得るためには「RSTRING_PTR(str)」とします．配列の
+場合には，それぞれ「RARRAY_LEN(ary)」，「RARRAY_PTR(ary)」と
+なります．
+
+Rubyの構造体を直接アクセスする時に気をつけなければならないこ
+とは，配列や文字列の構造体の中身は参照するだけで，直接変更し
+ないことです．直接変更した場合，オブジェクトの内容の整合性が
+とれなくなって，思わぬバグの原因になります．
+
+== CのデータをVALUEに変換する
+
+VALUEの実際の構造は
+
+FIXNUMの場合 ::
+
+  1bit左シフトして，LSBを立てる．
+
+その他のポインタの場合 ::
+
+  そのままVALUEにキャストする．
+
+となっています．よって，LSBをチェックすればVALUEがFIXNUMかど
+うかわかるわけです(ポインタのLSBが立っていないことを仮定して
+いる)．
+
+ですから，FIXNUM以外のRubyのオブジェクトの構造体は単にVALUE
+にキャストするだけでVALUEに変換出来ます．ただし，任意の構造
+体がVALUEにキャスト出来るわけではありません．キャストするの
+はRubyの知っている構造体(ruby.hで定義されているstruct RXxxx
+のもの)だけです．
+
+FIXNUMに関しては変換マクロを経由する必要があります．Cの整数
+からVALUEに変換するマクロは以下のものがあります．必要に応じ
+て使い分けてください．
+
+INT2FIX() :: もとの整数が31bitまたは63bit以内に収まる自信
+      	     がある時
+INT2NUM() :: 任意の整数からVALUEへ
+
+INT2NUM()は整数がFIXNUMの範囲に収まらない場合，Bignumに変換
+してくれます(が，少し遅い)．
+
+== Rubyのデータを操作する
+
+先程も述べた通り，Rubyの構造体をアクセスする時に内容の更新を
+行うことは勧められません．で，Rubyのデータを操作する時には
+Rubyが用意している関数を用いてください．
+
+ここではもっとも使われるであろう文字列と配列の生成/操作を行
+い関数をあげます(全部ではないです)．
+
+=== 文字列に対する関数
+
+rb_str_new(const char *ptr, long len) ::
+
+  新しいRubyの文字列を生成する．
+
+rb_str_new2(const char *ptr)
+rb_str_new_cstr(const char *ptr)
+
+  Cの文字列からRubyの文字列を生成する．この関数の機能は
+  rb_str_new(ptr, strlen(ptr))と同等である．
+
+rb_tainted_str_new(const char *ptr, long len)
+
+  汚染マークが付加された新しいRubyの文字列を生成する．外部
+  からのデータに基づく文字列には汚染マークが付加されるべき
+  である．
+
+rb_tainted_str_new2(const char *ptr)
+rb_tainted_str_new_cstr(const char *ptr)
+
+  Cの文字列から汚染マークが付加されたRubyの文字列を生成する．
+
+rb_sprintf(const char *format, ...)
+rb_vsprintf(const char *format, va_list ap)
+
+  Cの文字列formatと続く引数をprintf(3)のフォーマットにしたがって
+  整形し，Rubyの文字列を生成する．
+
+rb_str_cat(VALUE str, const char *ptr, long len)
+
+  Rubyの文字列strにlenバイトの文字列ptrを追加する．
+
+rb_str_cat2(VALUE str, const char* ptr)
+
+  Rubyの文字列strにCの文字列ptrを追加する．この関数の機能は
+  rb_str_cat(str, ptr, strlen(ptr))と同等である．
+
+rb_str_catf(VALUE str, const char* format, ...)
+rb_str_vcatf(VALUE str, const char* format, va_list ap)
+
+  Cの文字列formatと続く引数をprintf(3)のフォーマットにしたがって
+  整形し，Rubyの文字列strに追加する．この関数の機能は，それぞれ
+  rb_str_cat2(str, rb_sprintf(format, ...)) や
+  rb_str_cat2(str, rb_vsprintf(format, ap)) と同等である．
+
+rb_enc_str_new(const char *ptr, long len, rb_encoding *enc)
+
+  指定されたエンコーディングでRubyの文字列を生成する.
+
+rb_usascii_str_new(const char *ptr, long len)
+rb_usascii_str_new_cstr(const char *ptr)
+
+  エンコーディングがUS-ASCIIのRubyの文字列を生成する.
+
+rb_str_resize(VALUE str, long len)
+
+  Rubyの文字列のサイズをlenバイトに変更する．strの長さは前
+  以てセットされていなければならない．lenが元の長さよりも短
+  い時は，lenバイトを越えた部分の内容は捨てられる．lenが元
+  の長さよりも長い時は，元の長さを越えた部分の内容は保存さ
+  れないでゴミになるだろう．この関数の呼び出しによって
+  RSTRING_PTR(str)が変更されるかもしれないことに注意．
+
+rb_str_set_len(VALUE str, long len)
+
+  Rubyの文字列のサイズをlenバイトにセットする．strが変更可
+  能でなければ例外が発生する．RSTRING_LEN(str)とは無関係に，
+  lenバイトまでの内容は保存される．lenはstrの容量を越えてい
+  てはならない．
+
+
+== 配列に対する関数
+
+rb_ary_new()
+
+  要素が0の配列を生成する．
+
+rb_ary_new2(long len)
+
+  要素が0の配列を生成する．len要素分の領域をあらかじめ割り
+  当てておく．
+
+rb_ary_new3(long n, ...)
+
+  引数で指定したn要素を含む配列を生成する．
+
+rb_ary_new4(long n, VALUE *elts)
+
+  配列で与えたn要素の配列を生成する．
+
+rb_ary_to_ary(VALUE obj)
+
+  オブジェクトを配列に変換する.
+  Object#to_aryと同等である.
+
+他にも配列を操作する関数が多数ある. これらは
+引数aryに配列を渡さなければならない. さもないと
+コアを吐く.
+
+rb_ary_aref(argc, VALUE *argv, VALUE ary)
+
+  Array#[]と同等.
+
+rb_ary_entry(VALUE ary, long offset)
+
+  ary[offset]
+
+rb_ary_subseq(VALUE ary, long beg, long len)
+
+  ary[beg, len]
+
+rb_ary_push(VALUE ary, VALUE val)
+rb_ary_pop(VALUE ary)
+rb_ary_shift(VALUE ary)
+rb_ary_unshift(VALUE ary, VALUE val)
+
+rb_ary_cat(VALUE ary, const VALUE *ptr, long len)
+
+  配列aryにptrからlen個のオブジェクトを追加する．
+
+= 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)
+
+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．
+
+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)
+
+=== メソッド/特異メソッド定義
+
+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_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．
+
+メソッドを定義する関数はまだいくつかあります. ひとつはメソッド
+名としてIDを取ります. IDについては2.2.2を参照.
+
+  void rb_define_method_id(VALUE klass, ID name,
+                           VALUE (*func)(ANYARGS), int argc)
+
+private/protectedなメソッドを定義するふたつの関数があります.
+
+  void rb_define_private_method(VALUE klass, const char *name,
+				VALUE (*func)(), int argc)
+  void rb_define_protected_method(VALUE klass, const char *name,
+			          VALUE (*func)(), int argc)
+
+privateメソッドとは関数形式でしか呼び出すことの出来ないメソッ
+ドです．
+
+最後に， rb_define_module関数はモジュール関数を定義します．
+モジュール関数とはモジュールの特異メソッドであり，同時に
+privateメソッドでもあるものです．例をあげるとMathモジュール
+のsqrt()などがあげられます．このメソッドは
+
+  Math.sqrt(4)
+
+という形式でも
+
+  include Math
+  sqrt(4)
+
+という形式でも使えます．モジュール関数を定義する関数は以下の
+通りです．
+
+  void rb_define_module_function(VALUE module, const char *name,
+		                 VALUE (*func)(), int argc)
+
+関数的メソッド(Kernelモジュールのprivate method)を定義するた
+めの関数は以下の通りです．
+
+  void rb_define_global_function(const char *name, VALUE (*func)(), int argc)
+
+
+メソッドの別名を定義するための関数は以下の通りです．
+
+  void rb_define_alias(VALUE module, const char* new, const char* old);
+
+属性の取得・設定メソッドを定義するには
+
+  void rb_define_attr(VALUE klass, const char *name, int read, int write)
+
+クラスメソッドallocateを定義したり削除したりするための関数は
+以下の通りです．
+
+  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
+  void rb_undef_alloc_func(VALUE klass);
+
+funcはクラスを引数として受け取って，新しく割り当てられたイン
+スタンスを返さなくてはなりません．このインスタンスは，外部リ
+ソースなどを含まない，できるだけ「空」のままにしておいたほう
+がよいでしょう．
+
+=== 定数定義
+
+拡張ライブラリが必要な定数はあらかじめ定義しておいた方が良い
+でしょう．定数を定義する関数は二つあります．
+
+  void rb_define_const(VALUE klass, const char *name, VALUE val)
+  void rb_define_global_const(const char *name, VALUE val)
+
+前者は特定のクラス/モジュールに属する定数を定義するもの，後
+者はグローバルな定数を定義するものです．
+
+== Rubyの機能をCから呼び出す
+
+既に『1.5 Rubyのデータを操作する』で一部紹介したような関数を
+使えば，Rubyの機能を実現している関数を直接呼び出すことが出来
+ます．
+
+# このような関数の一覧表はいまのところありません．ソースを見
+# るしかないですね．
+
+それ以外にもRubyの機能を呼び出す方法はいくつかあります．
+
+=== Rubyのプログラムをevalする
+
+CからRubyの機能を呼び出すもっとも簡単な方法として，文字列で
+与えられたRubyのプログラムを評価する以下の関数があります．
+
+  VALUE rb_eval_string(const char *str)
+
+この評価は現在の環境で行われます．つまり，現在のローカル変数
+などを受け継ぎます．
+
+評価は例外を発生するかもしれないことに注意しましょう. より安全
+な関数もあります.
+
+  VALUE rb_eval_string_protect(const char *str, int *state)
+
+この関数はエラーが発生するとnilを返します．そして，成功時には
+*stateはゼロに，さもなくば非ゼロになります．
+
+=== IDまたはシンボル
+
+Cから文字列を経由せずにRubyのメソッドを呼び出すこともできま
+す．その前に，Rubyインタプリタ内でメソッドや変数名を指定する
+時に使われているIDについて説明しておきましょう．
+
+IDとは変数名，メソッド名を表す整数です．Rubyの中では
+
+ :識別子
+
+または
+
+ :"任意の文字列"
+
+でアクセスできます．Cからこの整数を得るためには関数
+
+  rb_intern(const char *name)
+  rb_intern_str(VALUE name)
+
+を使います．Rubyから引数として与えられたシンボル(または文字
+列)をIDに変換するには以下の関数を使います．
+
+  rb_to_id(VALUE symbol)
+  rb_check_id(volatile VALUE *name)
+  rb_check_id_cstr(const char *name, long len, rb_encoding *enc)
+
+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
+字列に変換しようとします．第二の関数はその変換結果を*nameに保
+存し,その名前が既知のシンボルでない場合は0を返します．この関
+数が0以外を返した場合は*nameは常にシンボルか文字列であり、0を
+返した場合は常に文字列です．第三の関数はRubyの文字列ではなく
+NUL終端されたCの文字列を使います．
+
+=== CからRubyのメソッドを呼び出す
+
+Cから文字列を経由せずにRubyのメソッドを呼び出すためには以下
+の関数を使います．
+
+  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
+
+この関数はオブジェクトrecvのmidで指定されるメソッドを呼び出
+します．その他に引数の指定の仕方が違う以下の関数もあります．
+
+  VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv)
+  VALUE rb_apply(VALUE recv, ID mid, VALUE args)
+
+applyには引数としてRubyの配列を与えます．
+
+=== 変数/定数を参照/更新する
+
+Cから関数を使って参照・更新できるのは，定数，インスタンス変
+数です．大域変数は一部のものはCの大域変数としてアクセスでき
+ます．ローカル変数を参照する方法は公開していません．
+
+オブジェクトのインスタンス変数を参照・更新する関数は以下の通
+りです．
+
+  VALUE rb_ivar_get(VALUE obj, ID id)
+  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
+
+idはrb_intern()で得られるものを使ってください．
+
+定数を参照するには以下の関数を使ってください．
+
+  VALUE rb_const_get(VALUE obj, ID id)
+
+定数を新しく定義するためには『2.1.3 定数定義』で紹介さ
+れている関数を使ってください．
+
+= RubyとCとの情報共有
+
+C言語とRubyの間で情報を共有する方法について解説します．
+
+== Cから参照できるRubyの定数
+
+以下のRubyの定数はCのレベルから参照できます．
+
+  Qtrue
+  Qfalse
+
+真偽値．QfalseはC言語でも偽とみなされます(つまり0)．
+
+  Qnil
+
+C言語から見た「nil」．
+
+== CとRubyで共有される大域変数
+
+CとRubyで大域変数を使って情報を共有できます．共有できる大域
+変数にはいくつかの種類があります．そのなかでもっとも良く使わ
+れると思われるのはrb_define_variable()です．
+
+  void rb_define_variable(const char *name, VALUE *var)
+
+この関数はRubyとCとで共有する大域変数を定義します．変数名が
+`$'で始まらない時には自動的に追加されます．この変数の値を変
+更すると自動的にRubyの対応する変数の値も変わります．
+
+またRuby側からは更新できない変数もあります．このread onlyの
+変数は以下の関数で定義します．
+
+  void rb_define_readonly_variable(const char *name, VALUE *var)
+
+これら変数の他にhookをつけた大域変数を定義できます．hook付き
+の大域変数は以下の関数を用いて定義します．hook付き大域変数の
+値の参照や設定はhookで行う必要があります．
+
+  void rb_define_hooked_variable(const char *name, VALUE *var,
+				 VALUE (*getter)(), void (*setter)())
+
+この関数はCの関数によってhookのつけられた大域変数を定義しま
+す．変数が参照された時には関数getterが，変数に値がセットされ
+た時には関数setterが呼ばれる．hookを指定しない場合はgetterや
+setterに0を指定します．
+# getterもsetterも0ならばrb_define_variable()と同じになる．
+
+getterとsetterの仕様は次の通りです．
+
+  VALUE (*getter)(ID id, VALUE *var);
+  void (*setter)(VALUE val, ID id, VALUE *var);
+
+
+それから，対応するCの変数を持たないRubyの大域変数を定義する
+こともできます. その変数の値はフック関数のみによって取得・設定
+されます.
+
+  void rb_define_virtual_variable(const char *name,
+				  VALUE (*getter)(), void (*setter)())
+
+この関数によって定義されたRubyの大域変数が参照された時には
+getterが，変数に値がセットされた時にはsetterが呼ばれます．
+
+getterとsetterの仕様は以下の通りです．
+
+  (*getter)(ID id);
+  (*setter)(VALUE val, ID id);
+
+== CのデータをRubyオブジェクトにする
+
+Cの世界で定義されたデータ(構造体)をRubyのオブジェクトとして
+取り扱いたい場合がありえます．このような場合には，Dataという
+RubyオブジェクトにCの構造体(へのポインタ)をくるむことでRuby
+オブジェクトとして取り扱えるようになります．
+
+Dataオブジェクトを生成して構造体をRubyオブジェクトにカプセル
+化するためには，以下のマクロを使います．
+
+  Data_Wrap_Struct(klass, mark, free, sval)
+
+このマクロの戻り値は生成されたDataオブジェクトです．
+
+klassはこのDataオブジェクトのクラスです．ptrはカプセル化する
+Cの構造体へのポインタです．markはこの構造体がRubyのオブジェ
+クトへの参照がある時に使う関数です．そのような参照を含まない
+時には0を指定します．
+
+# そのような参照は勧められません．
+
+freeはこの構造体がもう不要になった時に呼ばれる関数です．この
+関数がガーベージコレクタから呼ばれます．これが-1の場合は，単
+純に開放されます．
+
+markおよびfree関数はGC実行中に呼び出されます.
+なお, GC実行中はRubyオブジェクトのアロケーションは禁止されま
+す. よって, markおよびfree関数でRubyオブジェクトのアロケーシ
+ョンは行わないでください.
+
+Cの構造体の割当とDataオブジェクトの生成を同時に行うマクロと
+して以下のものが提供されています．
+
+  Data_Make_Struct(klass, type, mark, free, sval)
+
+このマクロの戻り値は生成されたDataオブジェクトです．
+
+klass, mark, freeはData_Wrap_Structと同じ働きをします．type
+は割り当てるC構造体の型です．割り当てられた構造体は変数sval
+に代入されます．この変数の型は (type*) である必要があります．
+
+Dataオブジェクトからポインタを取り出すのは以下のマクロを用い
+ます．
+
+  Data_Get_Struct(obj, type, sval)
+
+Cの構造体へのポインタは変数svalに代入されます．
+
+これらのDataの使い方はちょっと分かりにくいので，後で説明する
+例題を参照してください．
+
+= 例題 - dbmパッケージを作る
+
+ここまでの説明でとりあえず拡張ライブラリは作れるはずです．
+Rubyのextディレクトリにすでに含まれているdbmライブラリを例に
+して段階的に説明します．
+
+== ディレクトリを作る
+
+  % mkdir ext/dbm
+
+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Enumerate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)
+  {
+      /* ... */
+  }
+
+第1引数はself，第2引数はRubyの配列です．
+
+*注意事項*
+
+Rubyと共有はしないがRubyのオブジェクトを格納する可能性のある
+Cの大域変数は以下の関数を使ってRubyインタプリタに変数の存在
+を教えてあげてください．でないとGCでトラブルを起こします．
+
+  void rb_global_variable(VALUE *var)
+
+== extconf.rbを用意する
+
+Makefileを作る場合の雛型になるextconf.rbというファイルを作り
+ます．extconf.rbはライブラリのコンパイルに必要な条件のチェッ
+クなどを行うことが目的です．まず，
+
+  require 'mkmf'
+
+をextconf.rbの先頭に置きます．extconf.rbの中では以下のRuby関
+数を使うことが出来ます．
+
+  have_library(lib, func): ライブラリの存在チェック
+  have_func(func, header): 関数の存在チェック
+  have_header(header): ヘッダファイルの存在チェック
+  create_makefile(target[, target_prefix]): Makefileの生成
+
+以下の変数を使うことができます．
+
+  $CFLAGS: コンパイル時に追加的に指定するフラグ(-Oなど)
+  $CPPFLAGS: プリプロセッサに追加的に指定するフラグ(-Iや-Dなど)
+  $LDFLAGS: リンク時に追加的に指定するフラグ(-Lなど)
+  $objs: リンクされるオブジェクトファイル名のリスト
+
+オブジェクトファイルのリストは，通常はソースファイルを検索し
+て自動的に生成されますが，makeの途中でソースを生成するような
+場合は明示的に指定する必要があります．
+
+ライブラリをコンパイルする条件が揃わず，そのライブラリをコン
+パイルしない時にはcreate_makefileを呼ばなければMakefileは生
+成されず，コンパイルも行われません．
+
+== dependを用意する
+
+もし，ディレクトリにdependというファイルが存在すれば，
+Makefileが依存関係をチェックしてくれます．
+
+  % gcc -MM *.c > depend
+
+などで作ることが出来ます．あって損は無いでしょう．
+
+== Makefileを生成する
+
+Makefileを実際に生成するためには
+
+  ruby extconf.rb
+
+とします．extconf.rbに require 'mkmf' の行がない場合にはエラー
+になりますので，引数を追加して
+
+  ruby -r mkmf extconf.rb
+
+としてください．
+
+site_ruby ディレクトリでなく，
+vendor_ruby ディレクトリにインストールする場合には
+以下のように --vendor オプションを加えてください．
+
+  ruby extconf.rb --vendor
+
+ディレクトリをext以下に用意した場合にはRuby全体のmakeの時に
+自動的にMakefileが生成されますので，このステップは不要です．
+
+== makeする
+
+動的リンクライブラリを生成する場合にはその場でmakeしてくださ
+い．必要であれば make install でインストールされます．
+
+ext以下にディレクトリを用意した場合は，Rubyのディレクトリで
+makeを実行するとMakefileを生成からmake，必要によってはそのモ
+ジュールのRubyへのリンクまで自動的に実行してくれます．
+extconf.rbを書き換えるなどしてMakefileの再生成が必要な時はま
+たRubyディレクトリでmakeしてください．
+
+拡張ライブラリはmake installでRubyライブラリのディレクトリの
+下にコピーされます．もし拡張ライブラリと協調して使うRubyで記
+述されたプログラムがあり，Rubyライブラリに置きたい場合には，
+拡張ライブラリ用のディレクトリの下に lib というディレクトリ
+を作り，そこに 拡張子 .rb のファイルを置いておけば同時にイン
+ストールされます．
+
+== デバッグ
+
+まあ，デバッグしないと動かないでしょうね．ext/Setupにディレ
+クトリ名を書くと静的にリンクするのでデバッガが使えるようにな
+ります．その分コンパイルが遅くなりますけど．
+
+== できあがり
+
+後はこっそり使うなり，広く公開するなり，売るなり，ご自由にお
+使いください．Rubyの作者は拡張ライブラリに関して一切の権利を
+主張しません．

+  状況の時呼ぶ．インタープリタはコアダンプし直ちに終了する．
+  例外処理は一切行なわれない．
+
+== Rubyの初期化・実行

+  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
+
+rb_event_hook_func_tの定義は以下の通りです:
+
+  typedef void (*rb_event_hook_func_t)(rb_event_t event, VALUE data,
+                                       VALUE self, ID id, VALUE klass)
+
+rb_add_event_hook() の第3引数 data は，フック関数の第2引数と
+して渡されます．これは1.8では現在のNODEへのポインタでした．以
+下の RB_EVENT_HOOKS_HAVE_CALLBACK_DATA も参照してください．
+
+  int rb_remove_event_hook(rb_event_hook_func_t func)
+
+指定されたフック関数を削除します．

+  を意味する．たとえば，HAVE_RUBY_ST_H が定義されている場合は
+  単なる st.h ではなく ruby/st.h を使用する．
+
+RB_EVENT_HOOKS_HAVE_CALLBACK_DATA ::
+
+  rb_add_event_hook() がフック関数に渡す data を第3引数として
+  受け取ることを意味する．

+= Rubyとは
+
+Rubyはシンプルかつ強力なオブジェクト指向スクリプト言語です．
+Rubyは最初から純粋なオブジェクト指向言語として設計されていま
+すから，オブジェクト指向プログラミングを手軽に行う事が出来ま
+す．もちろん通常の手続き型のプログラミングも可能です．
+
+Rubyはテキスト処理関係の能力などに優れ，Perlと同じくらい強力
+です．さらにシンプルな文法と，例外処理やイテレータなどの機構
+によって，より分かりやすいプログラミングが出来ます．
+
+
+== Rubyの特長
+
+*   シンプルな文法
+*   普通のオブジェクト指向機能(クラス，メソッドコールなど)
+*   特殊なオブジェクト指向機能(Mixin, 特異メソッドなど)
+*   演算子オーバーロード
+*   例外処理機能
+*   イテレータとクロージャ
+*   ガーベージコレクタ
+*   ダイナミックローディング (アーキテクチャによる)
+*   移植性が高い．多くのUnix-like/POSIX互換プラットフォーム上で
+    動くだけでなく，Windows， Mac OS X，BeOSなどの上でも動く
+    cf. http://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatformsJa
+
+== 入手法
+
+=== FTPで
+
+以下の場所においてあります．
+
+ftp://ftp.ruby-lang.org/pub/ruby/
+
+=== Subversionで
+
+開発先端のソースコードは次のコマンドで取得できます．
+
+  $ svn co http://svn.ruby-lang.org/repos/ruby/trunk/ ruby
+
+他に開発中のブランチの一覧は次のコマンドで見られます．
+
+  $ svn ls http://svn.ruby-lang.org/repos/ruby/branches/
+
+=== Gitで
+
+SubversionのミラーをGitHubに公開しています．
+以下のコマンドでリポジトリを取得できます．
+
+  $ git clone git://github.com/ruby/ruby.git
+
+== ホームページ
+
+RubyのホームページのURLは
+
+http://www.ruby-lang.org/
+
+です．
+
+
+== メーリングリスト
+
+Rubyのメーリングリストがあります。参加希望の方は
+
+mailto:ruby-list-ctl@ruby-lang.org
+
+まで本文に
+
+   subscribe YourFirstName YourFamilyName
+
+と書いて送って下さい。
+
+Ruby開発者向けメーリングリストもあります。こちらではrubyのバ
+グ、将来の仕様拡張など実装上の問題について議論されています。
+参加希望の方は
+
+mailto:ruby-dev-ctl@ruby-lang.org
+
+までruby-listと同様の方法でメールしてください。
+
+Ruby拡張モジュールについて話し合うruby-extメーリングリストと
+数学関係の話題について話し合うruby-mathメーリングリストと
+英語で話し合うruby-talkメーリングリストもあります。参加方法
+はどれも同じです。
+
+
+== コンパイル・インストール
+
+以下の手順で行ってください．
+
+1.   もし +configure+ ファイルが見つからない、もしくは
+     +configure.in+ より古いようなら、 +autoconf+ を実行して
+     新しく +configure+ を生成する
+
+2.   +configure+ を実行して +Makefile+ などを生成する
+
+     環境によってはデフォルトのCコンパイラ用オプションが付き
+     ます． +configure+ オプションで <tt>optflags=..</tt> <tt>warnflags=..</tt> 等
+     で上書きできます．
+
+3.   (必要ならば)+defines.h+ を編集する
+
+     多分，必要無いと思います．
+
+4.   (必要ならば)+ext/Setup+ に静的にリンクする拡張モジュールを
+     指定する
+
+     +ext/Setup+ に記述したモジュールは静的にリンクされます．
+
+     ダイナミックローディングをサポートしていないアーキテク
+     チャでは +Setup+ の1行目の「<tt>option nodynamic</tt>」という行のコ
+     メントを外す必要があります．また，このアーキテクチャで
+     拡張モジュールを利用するためには，あらかじめ静的にリン
+     クしておく必要があります．
+
+5.   +make+ を実行してコンパイルする
+
+6.   <tt>make check</tt>でテストを行う．
+
+     「<tt>check succeeded</tt>」と表示されれば成功です．ただしテスト
+     に成功しても完璧だと保証されている訳ではありません．
+
+7.   <tt>make install</tt>
+
+     以下のディレクトリを作って，そこにファイルをインストー
+     ルします．
+
+     * <tt>${DESTDIR}${prefix}/bin</tt>
+     * <tt>${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
+     * <tt>${DESTDIR}${prefix}/lib</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/share/man/man1</tt>
+     * <tt>${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system</tt>
+
+     RubyのAPIバージョンが'_x.y.z_'であれば，<tt>${MAJOR}</tt>は
+     '_x_'で，<tt>${MINOR}</tt>は'_y_'，<tt>${TEENY}</tt>は'_z_'です．
+
+     <b>注意</b>: APIバージョンの +teeny+ は，Rubyプログラムのバージョ
+     ンとは異なることがあります．
+
+     +root+ で作業する必要があるかもしれません．
+
+もし，コンパイル時にエラーが発生した場合にはエラーのログとマ
+シン，OSの種類を含むできるだけ詳しいレポートを作者に送ってく
+ださると他の方のためにもなります．
+
+
+== 移植
+
+UNIXであれば +configure+ がほとんどの差異を吸収してくれるはずで
+すが，思わぬ見落としがあった場合(あるに違いない)，作者にその
+ことをレポートすれば，解決できるかも知れません．
+
+アーキテクチャにもっとも依存するのはGC部です．RubyのGCは対象
+のアーキテクチャが<tt>setjmp()</tt>または<tt>getcontext()</tt>によって全てのレ
+ジスタを +jmp_buf+ や +ucontext_t+ に格納することと， +jmp_buf+ や
++ucontext_t+ とスタックが32bitアラインメントされていることを仮定
+しています．特に前者が成立しない場合の対応は非常に困難でしょう．
+後者の解決は比較的簡単で， +gc.c+ でスタックをマークしている
+部分にアラインメントのバイト数だけずらしてマークするコードを
+追加するだけで済みます．<tt>defined(\_\_mc68000\_\_)</tt>で括られてい
+る部分を参考にしてください．
+
+レジスタウィンドウを持つCPUでは，レジスタウィンドウをスタッ
+クにフラッシュするアセンブラコードを追加する必要があるかも知
+れません．
+
+
+== 配布条件
+
++COPYING.ja+ ファイルを参照してください。
+
+
+== 著者
+
+コメント，バグレポートその他は mailto:matz@ruby-lang.jp まで．

+ *  - the block returns false for any element whose index is less than
+ *    i, and
+ *  - the block returns true for any element whose index is greater

+ *     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

+ *  that satisfies the block), this method returns nil.

+ *  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) #=> [0, 0, 0]
+ *
+ *  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]]
+ *
+ *  == 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 }     #=> [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]
+ *

+     * ilink32
+
+(3) If you want to build from CVS source, following commands are required.
+     * bison ((<URL:http://gnuwin32.sourceforge.net/packages/bison.htm>))
+     * sed   ((<URL:http://gnuwin32.sourceforge.net/packages/sed.htm>))
+
+(4) We strongly recommend to build ruby on C++Builder, to link following files.
+     * usebormm.lib
+     * memmgr.lib
+
+    RTL's internal memory manager cannot handle large memory block properly,
+    so we should use borlndmm.dll instead.
+     10000.times { "" << "." * 529671; GC.start } # crash
+
+== How to compile and install
+
+(1) Execute bcc32\configure.bat on your build directory.
+     ex. c:\src\ruby> bcc32\configure.bat
+    You can specify the target platform as an argument.
+    For example, run `((%configure i686-bccwin32%))'
+    You can also specify the install directory.
+    For example, run `((%configure --prefix=<install_directory>%))'
+    Default of the install directory is /usr .
+    The default ((|<PLATFORM>|)) is `(({i386-bccwin32}))'.
+     
+(2) Change ((|RUBY_INSTALL_NAME|)) and ((|RUBY_SO_NAME|)) in (({Makefile}))
+    if you want to change the name of the executable files. 
+    And add ((|RUBYW_INSTALL_NAME|)) to change the name of the
+    executable without console window if also you want.
+
+(3) Run `((%make%))'
+
+(4) Run `((%make test%))'
+
+(5) Run `((%make install%))'
+
+(6) Requires dynamic RTL (cc3250.dll on C++Builder5) and borlndmm.dll (If built with
+    usebormm.lib) to use installed binary. These files are ordinary in bcc32's bin
+    directory.
+
+== Icons
+
+Any icon files(*.ico) in the build directory, directories specified with
+((|icondirs|)) make variable and (({win32})) directory under the ruby
+source directory will be included in DLL or executable files, according
+to their base names.
+    $(RUBY_INSTALL_NAME).ico or ruby.ico   --> $(RUBY_INSTALL_NAME).exe
+    $(RUBYW_INSTALL_NAME).ico or rubyw.ico --> $(RUBYW_INSTALL_NAME).exe
+    the others                             --> $(RUBY_SO_NAME).dll
+
+Although no icons are distributed with the ruby source or in the official 
+site, you can use anything you like. For example, followings are written 
+in Japanese, but you can download at least.
+
+* ((<URL:http://member.nifty.ne.jp/ueivu/rubyico.html>)) or
+  ((<zipped icons|URL:http://member.nifty.ne.jp/ueivu/Ruby_ico.zip>))
+* ((<URL:http://homepage1.nifty.com/a_nakata/ruby/>)) or
+  ((<icon itself|URL:http://homepage1.nifty.com/a_nakata/ruby/RubyIcon.ico>))
+
+== Build examples
+
+* Build on the ruby source directory.
+
+  ex.)
+    ruby source directory:  C:\ruby
+    build directory:        C:\ruby
+    install directory:      C:\usr\local
+
+    C:
+    cd \ruby
+    bcc32\configure --prefix=/usr/local
+    make
+    make test
+    make install
+
+* Build on the relative directory from the ruby source directory and CPU type 
+  i386.
+
+  ex.)
+    ruby source directory:  C:\ruby
+    build directory:        C:\ruby\bccwin32
+    install directory:      C:\usr\local
+    CPU                     i386
+    
+    C:
+    cd \ruby
+    mkdir bccwin32
+    cd bccwin32
+    ..\bcc32\configure --prefix=/usr/local
+    make
+    make test
+    make install
+
+* Build on the different drive.
+
+  ex.)
+    ruby source directory:  C:\src\ruby
+    build directory:        D:\build\ruby
+    install directory:      C:\usr\local
+
+    D:
+    cd D:\build\ruby
+    C:\src\ruby\bcc32\configure --prefix=C:/usr/local
+    make
+    make test
+    make install
+
+== Bugs
+
+You can ((*NOT*)) use a path name contains any white space characters as
+the ruby source directory, this restriction comes from the behavior of
+(({!INCLUDE})) directives of (({MAKE})).
+((- you may call it a bug. -))

+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

+ *  Document-class: Continuation
+ *
+ *  Continuation objects are generated by Kernel#callcc,
+ *  after having +require+d <i>continuation</i>. They hold
+ *  a return address and execution context, allowing a nonlocal return
+ *  to the end of the <code>callcc</code> block from anywhere within a
+ *  program. Continuations are somewhat analogous to a structured
+ *  version of C's <code>setjmp/longjmp</code> (although they contain
+ *  more state, so you might consider them closer to threads).
+ *
+ *  For instance:
+ *
+ *     require "continuation"
+ *     arr = [ "Freddie", "Herbie", "Ron", "Max", "Ringo" ]
+ *     callcc{|cc| $cc = cc}
+ *     puts(message = arr.shift)
+ *     $cc.call unless message =~ /Max/
+ *
+ *  <em>produces:</em>
+ *
+ *     Freddie
+ *     Herbie
+ *     Ron
+ *     Max
+ *
+ *  This (somewhat contrived) example allows the inner loop to abandon
+ *  processing early:
+ *
+ *     require "continuation"
+ *     callcc {|cont|
+ *       for i in 0..4
+ *         print "\n#{i}: "
+ *         for j in i*5...(i+1)*5
+ *           cont.call() if j == 17
+ *           printf "%3d", j
+ *         end
+ *       end
+ *     }

+ *  Document-class: Fiber
+ *
+ *  Fibers are primitives for implementing light weight cooperative
+ *  concurrency in Ruby. Basically they are a means of creating code blocks
+ *  that can be paused and resumed, much like threads. The main difference
+ *  is that they are never preempted and that the scheduling must be done by
+ *  the programmer and not the VM.
+ *
+ *  As opposed to other stackless light weight concurrency models, each fiber
+ *  comes with a small 4KB stack. This enables the fiber to be paused from deeply
+ *  nested function calls within the fiber block.
+ *
+ *  When a fiber is created it will not run automatically. Rather it must be
+ *  be explicitly asked to run using the <code>Fiber#resume</code> method.
+ *  The code running inside the fiber can give up control by calling
+ *  <code>Fiber.yield</code> in which case it yields control back to caller
+ *  (the caller of the <code>Fiber#resume</code>).
+ *
+ *  Upon yielding or termination the Fiber returns the value of the last
+ *  executed expression
+ *
+ *  For instance:
+ *
+ *    fiber = Fiber.new do
+ *      Fiber.yield 1
+ *      2
+ *    end
+ *
+ *    puts fiber.resume
+ *    puts fiber.resume
+ *    puts fiber.resume
+ *
+ *  <em>produces</em>
+ *
+ *    1
+ *    2
+ *    FiberError: dead fiber called
+ *
+ *  The <code>Fiber#resume</code> method accepts an arbitrary number of
+ *  parameters, if it is the first call to <code>resume</code> then they
+ *  will be passed as block arguments. Otherwise they will be the return
+ *  value of the call to <code>Fiber.yield</code>
+ *
+ *  Example:
+ *
+ *    fiber = Fiber.new do |first|
+ *      second = Fiber.yield first + 2
+ *    end
+ *
+ *    puts fiber.resume 10
+ *    puts fiber.resume 14
+ *    puts fiber.resume 18
+ *
+ *  <em>produces</em>
+ *
+ *    12

+
+	* lib/webrick/httpauth/digestauth.rb (_authenticate):
+	  Literal texts in HTTP ABNF is case-insensitive (RFC2616 2.1),
+	  and a sample implementation in RFC2617 also ignores the case
+	  of algorithms. So now this ignores those cases.
+	  [ruby-dev:43965] [Feature #4936]
+
+	* lib/webrick/httpauth/digestauth.rb (initialize):
+	  Because of above, opera_hack is useless and removed.
+
+Tue Jul  5 01:30:01 2011  Yusuke Endoh  <mame@tsg.ne.jp>
+
+	* thread_pthread.c (native_sleep): cut the waiting time up to
+	  100,000,000 because Solaris cond_timedwait() return EINVAL if an
+	  argument is greater than current_time + 100,000,000.  This is
+	  considered as a kind of spurious wakeup.  The caller to native_sleep
+	  should care about spurious wakeup.

+
+Mon Jul  4 07:14:12 2011  NARUSE, Yui  <naruse@ruby-lang.org>

+
+Mon Jul  4 06:37:22 2011  Koichi Sasada  <ko1@atdot.net>
+
+	* include/ruby/intern.h, thread_pthread.c (rb_reserved_fd_p,
+	  RB_RESERVED_FD_P): added.  This C API is to limit to access
+	  fds which are used by RubyVM internal.  In this version of
+	  CRuby, return 1 if fd is communication pipe.
+	  If your application needs to close all file descriptors to
+	  present resource leak, skip internal fds using this C API.
+	  We also define a macro RB_RESERVED_FD_P(fd).  So you can write
+	    #ifndef RB_RESERVED_FD_P
+	    #define RB_RESERVED_FD_P(fd) 0
+	    #endif
+	  for Ruby 1.9.2 or previous version to write compatible extensions.

+
+Sun Jul  3 06:10:26 2011  KOSAKI Motohiro  <kosaki.motohiro@gmail.com>
+
+	* thread_pthread.c (get_stack): pthread_attr_getstack() doesn't
+	  return stack start address, but stack base address. Thus,
+	  we need to add stack size for getting stack start address.
+	  And, we don't have to decrease guard size twice.
+	* thread_pthread.c (thread_start_func_1): don't use inaccurate
+	  stack start guess if native_thread_init_stack() can be used.

+	* lib/benchmark (Benchmark#bmbm): bmbm should be consistent with bm

+	  consistent for #bm and #bmbm.
+	  But with times over 100s, the output contains no space between the
+	  label and the first time (user).
+	  Now both ensure there is always a space, even if that means 3 spaces
+	  with times under 10s (because it is formatted as %10.6f)

+	* test/benchmark: let labels be a constant

+	  silently ignoring lesser significant digits.  Required buffer
+	  length can be computable so you might at first think of
+	  allocating enough memory space on the fly using alloca().  That
+	  is a wrong idea because when using alloca there is always risk
+	  of integer overflow.  A function that accepts outer-process
+	  resources like this should not blindly trust its inputs.  In
+	  this particular case we just want to generate milliseconds
+	  resolution by strtod() so the string in question needs no more
+	  length than what we originally have.  Ignoring lesser
+	  significant digits should suffice I believe.

+	* test/net/imap/test_imap.rb: "localhost" not guaranteed to
+	  resolve to "127.0.0.1".  On my machine it is "::1" instead.
+	  The problem is, you have to connect to the imaps server via
+	  the canonical name written in a server certificate, and that
+	  of the server.cert is "localhost".  So you have to listen to
+	  the address of what "localhost" resolves to.  I think this
+	  situation cannot be resolved in a handy manner because the
+	  test "test_imaps_post_connection_check" is actually
+	  expecting to connect to a server via an address other than
+	  the CN.  On my machine several assertions won't pass because
+	  the test cannot connect to the server.
