Changeset 38446 for trunk/tests/phpunit/tests/comment/query.php

Message:

Comments: Don't do direct SQL query when fetching decendants.

The SQL query was built using the clauses compiled when querying for
top-level comments. But in cases where the top-level comment query
results are already in the cache, the SQL clauses are not built, and
so are unavailable for fill_descendants(). Instead, we call
get_comments(), using modified versions of the parameters passed
to the main WP_Comment_Query class.

Props Akeif, Rarst for testing.
Fixes #37696.
