Subject: ruby-dev summary #17208-17251

Hello,

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


---- ruby-dev #17208-17251 (2002-05-23 ... 2002-05-31) ----


[ruby-dev:17208] Etc

  Kazuhiro NISHIYAMA pointed out that Etc.passwd is not
  multithread(MT)-safe and ignores safe level.

  Since there is no MT-safe and portable way to access
  password database, it has not been solved yet.


[ruby-dev:17220] safe-level

  Hidetoshi NAGAI asked whether Proc object should be closed
  under modification of $SAFE. It is true in current ruby, and
  he want to make this behavior specified.


[ruby-dev:17221] Re: StringIO

  Wakou Aoyama proposed a method IO#size. It seems to be useful
  for StringIO and TempFile. 
  But some subclasses of IO (ex. Socket) cannot know their size
  correctly, so StringIO#size and TempFile#size, not IO#size,
  will be implemented.
  

[ruby-dev:17228] Re: ((1.2)..(3.4)).to_a

  Take_tk pointed out that (1.2)..(3.4) is something odd.

     p( ((1.2)..(3.4)).to_a ) #=> [1, 2, 3]

     But 1 is not included in 1.2 .. 3.4

  The fundamental problem is that Range class has some
  functions of Interval. #to_a method is natural for Range
  (ordered discrete set), but not uniquely for Interval
  (continuous set). Therefore, for Range objects of some
  classes (ex. Time or Float), definitions of #to_a method
  (or #each method) do not seem to be unique.
  The issue is still open.
