Defined in:
lib/makara/config_parser.rb

Overview

ConnectionUrlResolver is borrowed from Rails 4-2 since its location and implementation vary slightly among Rails versions, but the behavior is the same. Thus, borrowing the class should be the most future-safe way to parse a database url.

Expands a connection string into a hash.
