Bug #2359
closed
test_threads.rb:test_list
Description
=begin
In test/ruby/test_threads.rb:
test_list errors or hangs on Sparc64 Solaris.
I think the problem is that when using native threads, loop{} starves the other threads. I can "fix" running the internal eval'd code by changing the loop{} to be loop{puts 'fubar'}. But that only works if it sends to the terminal (the io causes the thread to let go). Since it's being captured by assert_in_out_err() that doesn't really work.
A work around is to change loop{} to loop{Thread.pass} but I don't know if this still tests what it is supposed to test.

I forgot to add that this test works in Linux 32 and 64.

Hi,
Sorry for late reply. I had trouble setting up Sparc Solaris.
I managed to prepare it, but I found the test worked for me.

I guess there may be some race condition, but we can't debug
unreproducible issue. So the priority is set to Low.
Contribution (debugging the issue and writing a patch) is
wanted.
