[ruby-core:44874] [ruby-trunk - Bug #6401][Open] Windows bug with File.pos

From: "jmthomas (Jason Thomas)" <redmine@...>

Issue #6401 has been reported by jmthomas (Jason Thomas).

----------------------------------------
Bug #6401: Windows bug with File.pos
https://bugs.ruby-lang.org/issues/6401

Author: jmthomas (Jason Thomas)
Status: Open
Priority: Normal

Category: 
Target version: 1.9.3
ruby -v: ruby 1.9.3p194 (2012-04-20) [i386-mingw32]


On Windows since Ruby 1.9.3p125 there have been issues with File.pos and File.readline. Ruby 1.9.3p0 does not have this issue. I have created the following test:

  def test_pos_with_readline
    t = make_tempfile
    random = Random.new(1234)
    open(t.path, "w") do |f|
      500.times do
        f.puts "X"*random.rand(80)
      end
    end
    i = 0
    lines = open(t.path,'r').read.split("\n")
    open(t.path, "r") do |f|
      lines.length.times do
        f.pos
        assert_equal lines[i], f.readline.chomp
        i += 1
      end
    end
  end

If you comment out the f.pos line this test case will pass. I originally submitted issue #6179 but the fixes applied there made things better but did not complete solve the problem. I apologize for the test case but it requires many lines with newlines to reproduce.
