* Fix freeze applying to cloned objectsCaleb Thompson2013-04-151-0/+7
| | | | | | | | | | | | | | | | Previously, freezing a cloned ActiveRecord object froze the original too. By cloning `@attributes` before freezing, we prevent cloned objects (which in Ruby share state of ivars) from being effected by `#freeze`. Resolves issue #4936, which has further information on this issue, as well as steps to reproduce. * Add a test case for `#freeze` not causing `cloned.frozen?` to be true. * Clone @attributes before freezing in `ActiveRecord::Core`, then reassign the cloned, frozen hash to the frozen model's `@attributes` ivar. /cc @steveklabnik

| | | | RUNNING_UNIT_TESTS file for details, but essentially you can now configure things in test/config.yml. You can also run tests directly via the command line, e.g. ruby path/to/test.rb (no rake needed, uses default db connection from test/config.yml). This will help us fix the CI by enabling us to isolate the different Rails versions to different databases.
