Description

Introduced with fec6eb782c01aa018813, there is an incompatibility with the mysql2 database adapter. One main feature of mysql2, besides being actively maintained, is that it is eagerly casting database values to matching ruby types.

In this case in app/models/wiki_page.rb:134 CP tries to convert a value retrieved from the database into a date. This works fine for most adapters. But in mysql2 this value is already a Time. Ergo passing it to Time.parse results in an error. Consequently, the rescue block is triggered and nil is assigned.

This misbehavior results in failing tests in test/unit/wiki_page_test.rb and test/functional/wiki_controller_test.rb.
