* probes.d: add DTrace probe declarations. [ruby-core:27448] * array.c (empty_ary_alloc, ary_new): added array create DTrace probe. * compile.c (rb_insns_name): allowing DTrace probes to access instruction sequence name. * Makefile.in: translate probes.d file to appropriate header file. * common.mk: declare dependencies on the DTrace header. * configure.in: add a test for existence of DTrace. * eval.c (setup_exception): add a probe for when an exception is raised. * gc.c: Add DTrace probes for mark begin and end, and sweep begin and end. * hash.c (empty_hash_alloc): Add a probe for hash allocation. * insns.def: Add probes for function entry and return. * internal.h: function declaration for compile.c change. * load.c (rb_f_load): add probes for `load` entry and exit, require entry and exit, and wrapping search_required for load path search. * object.c (rb_obj_alloc): added a probe for general object creation. * parse.y (yycompile0): added a probe around parse and compile phase. * string.c (empty_str_alloc, str_new): DTrace probes for string allocation. * test/dtrace/*: tests for DTrace probes. * vm.c (vm_invoke_proc): add probes for function return on exception raise, hash create, and instruction sequence execution. * vm_core.h: add probe declarations for function entry and exit. * vm_dump.c: add probes header file. * vm_eval.c (vm_call0_cfunc, vm_call0_cfunc_with_frame): add probe on function entry and return. * vm_exec.c: expose instruction number to instruction name function. * vm_insnshelper.c: add function entry and exit probes for cfunc methods. * vm_insnhelper.h: vm usage information is always collected, so uncomment the functions. 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 workaround enforces the fact that they exist on DragonFly. 12 15:59:38 2012 Shugo Maeda <shugo@ruby-lang.org> * vm_core.h (rb_call_info_t::refinements), compile.c (new_callinfo), vm_insnhelper.c (vm_search_method): revert r37616 because it's too slow. [ruby-dev:46477] * test/ruby/test_refinement.rb (test_inline_method_cache): skip the test until the bug is fixed efficiently. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37631 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

/*
* A Hash is a dictionary-like collection of unique keys and their values.
* Also called associative arrays, they are similar to Arrays, but where an
* Array uses integers as its index, a Hash allows you to use any object
* type.
*
* Hashes enumerate their values in the order that the corresponding keys
* were inserted.
*
* A Hash can be easily created by using its implicit form:
*
* grades = { "Jane Doe" => 10, "Jim Doe" => 6 }
*
* Hashes allow an alternate syntax form when your keys are always symbols.
* Instead of
*
* options = { :font_size => 10, :font_family => "Arial" }
*
* You could write it as:
*
* options = { font_size: 10, font_family: "Arial" }
*
* Each named key is a symbol you can access in hash:
*
* options[:font_size] # => 10
*
* A Hash can also be created through its ::new method:
*
* grades = Hash.new
* grades["Dorothy Doe"] = 9
*
* Hashes have a <em>default value</em> that is returned when accessing
* keys that do not exist in the hash. If no default is set +nil+ is used.
* You can set the default value by sending it as an argument to Hash.new:
*
* grades = Hash.new(0)
*
* Or by using the #default= method:
*
* grades = {"Timmy Doe" => 8}
* grades.default = 0
*
* Accessing a value in a Hash requires using its key:
*
* puts grades["Jane Doe"] # => 0
*
* === Common Uses
*
* Hashes are an easy way to represent data structures, such as
*
* books = {}
* books[:matz] = "The Ruby Language"
* books[:black] = "The Well-Grounded Rubyist"
*
* Hashes are also commonly used as a way to have named parameters in
* functions. Note that no brackets are used below. If a hash is the last
* argument on a method call, no braces are needed, thus creating a really
* clean interface:
*
* Person.create(name: "John Doe", age: 27)
*
* def self.create(params)
* @name = params[:name]
* @age = params[:age]
* end
*
* === Hash Keys
*
* Two objects refer to the same hash key when their <code>hash</code> value
* is identical and the two objects are <code>eql?</code> to each other.
*
* A user-defined class may be used as a hash key if the <code>hash</code>
* and <code>eql?</code> methods are overridden to provide meaningful
* behavior. By default, separate instances refer to separate hash keys.
*
* A typical implementation of <code>hash</code> is based on the
* object's data while <code>eql?</code> is usually aliased to the overridden
* <code>==</code> method:
*
* class Book
* attr_reader :author, :title
*
* def initialize(author, title)
* @author = author
* @title = title
* end
*
* def ==(other)
* self.class === other and
* other.author == @author and
* other.title == @title
* end
*
* alias eql? ==
*
* def hash
* @author.hash ^ @title.hash # XOR
* end
* end
*
* book1 = Book.new 'matz', 'Ruby in a Nutshell'
* book2 = Book.new 'matz', 'Ruby in a Nutshell'
*
* reviews = {}
*
* reviews[book1] = 'Great reference!'
* reviews[book2] = 'Nice and compact!'
*
* reviews.length #=> 1
*
