Subject: [ruby-core:52364] [ruby-trunk - Bug #7870] Time.now == "" causes an infinite loop


Issue #7870 has been updated by drbrain (Eric Hodel).


Fog breaks due to this change (it is how I discovered it):

https://github.com/fog/fog/blob/master/lib/fog/core/attributes.rb#L53-L62

This compares a Time with the empty string leading to the infinite loop.

Fog provides an API for cloud services such as Amazon AWS, OpenStack, etc. It is fairly popular.

=begin
This is a regression from 1.9.

2.0.0 branch:

  $ ./ruby20 -v ../branches/ruby_2_0_0/test.rb
  ruby 2.0.0dev (2013-02-08) [x86_64-darwin12.2.1]
  ../branches/ruby_2_0_0/test.rb:1: warning: possibly useless use of == in void context
  ../branches/ruby_2_0_0/test.rb:1: stack level too deep (SystemStackError)

1.9:

  $ ruby19 -v test.rb 
  ruby 1.9.3p374 (2013-01-15 revision 38858) [x86_64-darwin12.2.1]
  test.rb:1: warning: possibly useless use of == in void context

This also reproduces in trunk.
