Ruby does not 'ensure' when I 'retry' in 'rescue'

Question

Consider this begin-rescue-ensure block:

attempts=0
begin
  make_service_call()
rescue Exception
  retry unless attempts>2
  exit -1
ensure
  attemps += 1         


        

Answer 1

The ensure section is executed when leaving the begin statement (by any means) but when you retry, you're just moving around inside the statement so the ensure section will not be executed.

Try this version of your example to get a better idea of what's going on:

attempts = 0
begin
  make_service_call()
rescue Exception
  attempts += 1
  retry unless attempts > 2
  exit -1
ensure
  puts "ensure! #{attempts}"
end
