Removing the :growth parameter and making :interval an integer or (not AND) lambda

retry_upto.md

Time intervals between attempts

For fixed intervals, an :interval parameter can be passed indicating the time in seconds. The following example will sleep two seconds between attempts:

retry_upto(5, :interval => 2)

For customized intervals, the :interval parameter can be a lambda, which will be applied to the number of each attempt. For instance, the following code will sleep 3 seconds after the first attempt, 6 after the second, 9 after the third...

retry_upto(5, :interval => lambda{ |attempt| attempt * 3 })

Sounds fine, it allows increasing and decreasing series, as well as random ones.

Btw in the example it will sleep 3, 6, 9... (not 2, 6, 9).

Ops, good catch! :) Glad to know you like it!
