watson1978 92ea637c62 Improve Time#<=> performance
* time.c (wcmp): use internal cmp() function for comparing internal Fixnum value
    in Time objects. On 64-bit machine, Time object might have Fixnum object
    internally by default and cmp() can compare the Fixnum objects directly.

    Time#<=> will be faster around 60% on 64-bit machine.

* time.c (cmp): add optimized path for comparing internal Bignum value by using
    rb_big_cmp() API. On 32-bit machine, Time object might have Bignum object
    internally by default.

    Time#<=> will be faster around 50% on 32-bit machine.

    [ruby-dev:50034] [Bug #13354] [Fix GH-1546]

### Before
             user     system      total        real
Fixnum   1.410000   0.000000   1.410000 (  1.407848)
Bignum   1.550000   0.000000   1.550000 (  1.549145)

### After
             user     system      total        real
Fixnum   0.880000   0.000000   0.880000 (  0.886662)
Bignum   1.050000   0.000000   1.050000 (  1.047994)

### Test code
require 'benchmark'

Benchmark.bmbm do |x|

  x.report "Fixnum" do
    t1 = Time.now
    t2 = Time.now
    10000000.times do
      t1 <=> t2
    end
  end

  x.report "Bignum" do
    t1 = Time.at(2 ** 64)
    t2 = Time.at(2 ** 64 + 1)
    10000000.times do
      t1 <=> t2
    end
  end

end

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.

Features of Ruby

  • Simple Syntax
  • Normal Object-oriented Features (e.g. class, method calls)
  • Advanced Object-oriented Features (e.g. Mix-in, Singleton-method)
  • Operator Overloading
  • Exception Handling
  • Iterators and Closures
  • Garbage Collection
  • Dynamic Loading of Object Files (on some architectures)
  • Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, Mac OS X, Haiku, etc.) cf. https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatforms

How to get Ruby

For a complete list of ways to install Ruby, including using third-party tools like rvm, see:

https://www.ruby-lang.org/en/downloads/

The Ruby distribution files can be found on the following FTP site:

ftp://ftp.ruby-lang.org/pub/ruby/

The trunk of the Ruby source tree can be checked out with the following command:

$ svn co https://svn.ruby-lang.org/repos/ruby/trunk/ ruby

Or if you are using git then use the following command:

$ git clone git://github.com/ruby/ruby.git

There are some other branches under development. Try the following command to see the list of branches:

$ svn ls https://svn.ruby-lang.org/repos/ruby/branches/

Or if you are using git then use the following command:

$ git ls-remote git://github.com/ruby/ruby.git

How to compile and install

This is what you need to do to compile and install Ruby:

  1. If you want to use Microsoft Visual C++ to compile ruby, read win32/README.win32 instead of this document.

  2. If ./configure does not exist or is older than configure.in, run autoconf to (re)generate configure.

  3. Run ./configure, which will generate config.h and Makefile.

    Some C compiler flags may be added by default depending on your environment. Specify optflags=.. and warnflags=.. as necessary to override them.

  4. Edit defines.h if you need. Usually this step will not be needed.

  5. Remove comment mark(#) before the module names from ext/Setup (or add module names if not present), if you want to link modules statically.

    If you don't want to compile non static extension modules (probably on architectures which do not allow dynamic loading), remove comment mark from the line "#option nodynamic" in ext/Setup.

    Usually this step will not be needed.

  6. Run make.

    • On Mac, set RUBY_CODESIGN environment variable with a signing identity. It uses the identity to sign ruby binary. See also codesign(1).
  7. Optionally, run 'make check' to check whether the compiled Ruby interpreter works well. If you see the message "check succeeded", your ruby works as it should (hopefully).

  8. Run 'make install'

    This command will create the following directories and install files into them.

    • ${DESTDIR}${prefix}/bin
    • ${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}
    • ${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}
    • ${DESTDIR}${prefix}/lib
    • ${DESTDIR}${prefix}/lib/ruby
    • ${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}
    • ${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}
    • ${DESTDIR}${prefix}/lib/ruby/site_ruby
    • ${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}
    • ${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}
    • ${DESTDIR}${prefix}/lib/ruby/vendor_ruby
    • ${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}
    • ${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}
    • ${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}
    • ${DESTDIR}${prefix}/share/man/man1
    • ${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system

    If Ruby's API version is 'x.y.z', the ${MAJOR} is 'x', the ${MINOR} is 'y', and the ${TEENY} is 'z'.

    NOTE: teeny of the API version may be different from one of Ruby's program version

    You may have to be a super user to install ruby.

If you fail to compile ruby, please send the detailed error report with the error log and machine/OS type, to help others.

Some extension libraries may not get compiled because of lack of necessary external libraries and/or headers, then you will need to run 'make distclean-ext' to remove old configuration after installing them in such case.
