Backport #2559: IO#write raises Errno::EINVAL instead of expected Errno::EPIPE

• Status: Closed
• Assignee: shyouhei (Shyouhei Urabe)

=begin
Test case:

require 'thread'

a, b = IO.pipe
Thread.new do
a.read(1)
a.close
end

sleep 0.1 # wait for thread to begin
b.write("x" * (1024 * 16)) # should be larger than pipe/socket buffer size

b.write on 1.8.7-p174 raises Errno::EPIPE, as expected.
1.8.7-p248 raises Errno::EINVAL.

It looks like this bug was introduced in revision 25918. Unapplying that revision fixes the problem.

This affects a FreeBSD user on 1.8.7-p248. Can somebody please backport
this to the 1.8.7 branch?

Thanks
