Bug #5954

closed

IO.read_nonblock on IO.pipe generates Errno::EBADF (MinGW)

Added by luislavena (Luis Lavena) over 10 years ago. Updated almost 9 years ago.

Status:
Rejected
Priority:
Normal
Target version:
ruby -v:
1.9.3-p0 i386-mingw32 and 2.0.0dev
Backport:
[ruby-core:42295]

Description

=begin
Originally posted in [ruby-core:42103]:

The following example seems not to work under Windows:

r, w = IO.pipe

w.write "awesome" * 10

puts r.read_nonblock(8)

r.close
w.close

C:\Users\Luis>ruby -v t.rb
ruby 1.9.3p0 (2011-10-30) [i386-mingw32]
t.rb:5:in read_nonblock': Bad file descriptor (Errno::EBADF) from t.rb:5:in '

What is not clear is that using StringIO works:

require "stringio"

b = StringIO.new

b.write "awesome" * 10
b.rewind

puts b.read_nonblock(8)

b.close

C:\Users\Luis>ruby -v t2.rb
ruby 1.9.3p0 (2011-10-30) [i386-mingw32]
awesomea

Perhaps pipes are not open properly? Is this supported under Windows?
