Subject: ruby-dev summary 18458-18504

Hi all,

Sorry to post so late. This is a summary of ruby-dev ML
in these days.

---- ruby-dev #18458-18504 (2002-10-05 ... 2002-10-12) ----


  [ruby-dev:18471] How about String#clear?

YANAGAWA Kazuhisa proposed a method String#clear. The
method set the string empty, like Array#clear for Array.
It can be defined in Ruby as follows:

    class String
      def clear
        replace ""
      end
    end


  [ruby-dev:18465] warning for outer local variable assignment by block parameter

Tanaka Akira proposed warning for outer local variable assignment
by block parameter. 

(ex.)
  i = 0
  foo.each{|i|  ## <= warning
    .....


GOTO Kentaro doubted if it is not the rare conditions, but Matz
thinks that the frequency is not much for the risk, so it will
be implemented.


  [ruby-dev:18482] mem leak?

WATANABE Tetsuya pointed out that in 1.7.3(at 10/10 morning)
a script which uses large objects consumes huge memory and it
leads pageout.

Akira Tanaka suggested that GC should be triggered when
the amount of the allocated memory is more than two times
of the memory which used by live objects.

Nobuyoshi Nakada made a patch ([ruby-dev:18487]) and commited
it.
