Curious error from Rake

Ruby
1

Hi,

Ruby 1.8.6

I accidentally made a rake task a prerequisite of itself like so:

task :foo => [:foo] do
puts “hello”
end

And I got this output:

stopping only thread
note: use sleep to stop forever

No complaints really. Just thought it was an odd error, and I got zero
hits when I searched the ruby-talk archives. Anyone have an
explanation?

Regards,

Dan

Maybe an infinite loop causing a stack overflow?

2#878lilith:~/mess/current$ ruby -e ‘Thread.stop’
-e:1:in `stop’: stopping only thread (ThreadError)
note: use sleep to stop forever from -e:1

rake.rb:
def invoke
@lock.synchronize do
…
end
end

In short, you dead-locked the Rack mutex.
