Jonny Harris 4a9f5fe3be Taxonomy: Only store term_ids and object_ids in WP_Term_Query query caches.
The query cache currently implemented in `WP_Term_Query` caches the final output of the query, depending on what fields are requested. This is wasteful, as if a user requests `fields` => `all`, then an unlimited array of `WP_Term` objects could be stored in the object cache. Instead of storing the whole WP_Term object, this change only the term_id is stored. To get an array the full WP_Term objects, the `_prime_term_caches` function is called with an array of ids. In instances where a persistent object cache is not in use, then this will result in another SQL query to be run. After `_prime_term_caches` is called if this term is requested again in the same page load, then it will already be loaded into memory.  If a user runs `WP_Term_Query` with the fields param set to `all_with_object_id`, an array of objects containing both the term_id and object_ids are stored in cache. 

This change also improves the logic to load term meta caches. This change ensures that term meta is always primed for all terms loaded in the term query.

The short version:

1. Create a clean MySQL database and user.  DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory.  All files in that directory will be included by default.  Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run.  This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs.  Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
