Hi all,

This is a summary of ruby-dev ML in these days.

[ruby-dev:18978] st_foreach()

  Takaaki Tateishi posted a patch which optimizes st_foreach(),
  ruby's internal hash table iterator.  His patch:

    http://kt-www.jaist.ac.jp/~ttate/ftp/ruby/ruby-1.7.x.st.c.3.diff.gz

  This patch gives 2-4% reduction in execution time.

  Matz basically agreed with this patch, but also pointed out that we
  need better names for them.

[ruby-dev:18987] WinCE patch

  Takaaki Uematsu posted a patch which makes ruby "Windows CE machine
  ready".  This patch has been already applied to current CVS repository.

[ruby-dev:19002] Why to_ary is defined in URI?

  See this code:

    % ruby -ruri -e 'puts URI.parse("http://www.ruby-lang.org/")'
    http
    nil
    www.ruby-lang.org
    80
    /
    nil
    nil

  Kernel#puts converts an argument to the array with calling to_ary
  (if the method is defined).  With this issue, TANAKA Akira asked
  two questions:

    * Why URI#to_ary is defined?
    * Why Kernel#puts calls to_ary?

  Matz's answer (on Kernel#puts):

    * Because it is useful.

      Examples by this summary's author:

	# example 1:  output list of lines
	puts ARGF.map {|line| .... }

	# example 2:  list load pathes
	~ % ruby -e 'puts $:'

[ruby-dev:19009] ipaddr.rb

  UMEMOTO Hajime released a new library ipaddr.rb, which handles
  IP addresses (v4 and v6).  Check it out from ruby CVS repository.
  You can also get it via CVSWeb:

    http://www.ruby-lang.org/cgi-bin/cvsweb.cgi/rough/lib/ipaddr.rb?cvsroot=src&rev=1.1

[ruby-dev:19011] open-uri - very easy net access library

  TANAKA Akira released a new library open-uri.rb.
  Check it out from RAA:

    http://www.ruby-lang.org/en/raa-list.rhtml?id=758

  NOTE: This library requires ruby 1.7.

[ruby-dev:19004] Re: deprecated method
[ruby-dev:19025] Re: Different caller(0) in trace_func when NameError from toplevel between 1.6 and 1.7

  (Continued from [ruby-core:00575])

  See this code:

    % ruby -e '2.times { Object.new.type }'
    -e:1: warning: Object#type is deprecated; use Object#class
    -e:1: warning: Object#type is deprecated; use Object#class

  It is too verbose that the same warning is displaies many times.
  Nobuyuki Nakada once posted a patch which suppress this warning,
  but the patch breaks current behaviors.  A new framework is required
  now.  Matz has noted that the new framework must implement following
  functions:

    * multiple warning level
    * only one warning per one appearance
    * warning hook
