keyword ($Id$). ProgName with revision number was written in the 
  header line of each logfile for ease of tracking what version user
  is using in troubleshooting.  Logger is already stable enough.

I commit this on confirmation from Shyouhei.

  picks up when processing logger.rb by moving the require
  statement back before the comment block.  a patch from Hugh
  Sasse <hgs at dmu.ac.uk>.  [ruby-core:08422]

          dictating the way in which the logger should format the messages it
          displays.  Thanks to Nicholas Seckar (cf. [ruby-talk:153391]) and
          Daniel Berger.

        * lib/logger.rb (Logger): added VERSION constant.

        * lib/logger.rb: removed document for LogDevice. It is an
          implementation detail and is not a public interface.

        * test/logger/test_logger.rb: added tests.

          condition bug fixed.  [ruby-dev:26764]

        * test/logger/test_logger.rb: tests.


git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_8@9011 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_8@8777 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

        * lib/csv.rb (CSV.parse): [CAUTION] behavior changed.  in the past,
          CSV.parse accepts a filename to be read-opened (it was just a
          shortcut of CSV.open(filename, 'r')).  now CSV.parse accepts a
          string or a stream to be parsed e.g.
          CSV.parse("1,2\n3,r") #=> [['1', '2'], ['3', '4']]

        * lib/csv.rb: CSV::Row and CSV::Cell are deprecated.  these classes
          are removed in the future.  in the new csv.rb, row is represented
          as just an Array.  since CSV::Row was a subclass of Array, it won't
          hurt almost all programs except one which depended CSV::Row#match.
          and a cell is represented as just a String or nil(NULL).  this
          change will cause widespread destruction.

              CSV.open("foo.csv", "r") do |row|
                row.each do |cell|
                  if cell.is_null       # using Cell#is_null
                    p "(NULL)"
                  else
                    p cell.data         # using Cell#data
                  end
                end
              end

            must be just;

              CSV.open("foo.csv", "r") do |row|
                row.each do |cell|
                  if cell.nil?
                    p "(NULL)"
                  else
                    p cell
                  end
                end
              end

        * lib/csv.rb: [CAUTION] record separator(CR, LF, CR+LF) behavior
          change.  CSV.open, CSV.parse, and CSV,generate now do not force
          opened file binmode.  formerly it set binmode explicitly.

          with CSV.open, binmode of opened file depends the given mode
          parameter "r", "w", "rb", and "wb".  CSV.parse and CSV.generate open
          file with "r" and "w".

          setting mode properly is user's responsibility now.

        * lib/csv.rb: accepts String as a fs (field separator/column separator)
          and rs (record separator/row separator)

        * lib/csv.rb (CSV.read, CSV.readlines): added.  works as IO.read and
          IO.readlines in CSV format.

        * lib/csv.rb: added CSV.foreach(path, rs = nil, &block).  CSV.foreach
          now does not handle "| cmd" as a path different from IO.foreach.
          needed?

        * test/csv/test_csv.rb: updated.

        * test/ruby/test_float.rb: added test_strtod to test Float("0").

* numeric.c (flo_to_s): tweak output string based to preserve
  decimal point and to remove trailing zeros.  [ruby-talk:97891]

* string.c (rb_str_index_m): use unsigned comparison for T_FIXNUM
  search.  [ruby-talk:97342]

* hash.c (rb_hash_equal): returns true if two hashes have same set
  of key-value set.  [ruby-talk:97559]

* hash.c (rb_hash_eql): returns true if two hashes are equal and
  have same default values.

* string.c (rb_str_equal): always returns true or false, never
  returns nil. [ruby-dev:23404]

* io.c (rb_io_reopen): should use rb_io_check_io().
