Bug #8625: IO#read(len, buf) shortens buf even if data is not read actually
https://bugs.ruby-lang.org/issues/8625#change-45150
* Author: Nobuhiro IMAI
* Status: Assigned
* Priority: Normal
* Assignee: Masaki Matsushita
* Category: core
* Target version:
* ruby -v: ruby 2.1.0dev (2013-07-11 trunk 41923) [x86_64-linux]
* Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN
----------------------------------------
=begin
By r34580, IO#read(len, buf) does not expand buf until data is read actually,
but it still shortens if the original buf size is greater than len.
Is this an intended behavior?
def m(s)
IO.pipe do |r, w|
t = Thread.new{r.read(2, s)}
Thread.pass until t.stop?
t.kill
t.value
end
end
(1..3).each do |len|
s = "x" * len
s # => "x", "xx", "xxx"
m(s)
s # => "x", "xx", "xx"
end
=end
