Boone Gorges 1f5147bf83 Comments: Improve caching for hierarchical queries.
Hierarchical comment queries work by first fetching the IDs of top-level
comments, and then filling the descendant tree one level at a time based on the
top-level results. When top-level comment IDs are found in the cache,
`WP_Comment_Query` does not generate the SQL used to fetch these comments. In
this case, the `fill_descendants()` query does not have enough information
to fill children. As a result, descendant comments were failing to be filled
in cases where the top-level comments were found in the cache.

This was a minor bug previously, because comment caches were not maintained
between pageloads. Since comment caches are now persistent [37613], the problem
becomes evident anywhere that a persistent object cache is in use.

The solution is to cache parent-child relationships, so that when top-level
comments are found in the cache, descendant comments should be found there as
well.

Fixes #36487.

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.
