Changeset 53857 for trunk/src/wp-includes/rewrite.php

Message:

Rewrite rules: Prevent malformed date requests throwing notices.

Ensure that date queries contain each component before attempting to use them. This prevents http requests triggering notices if a portion of the date is missing. For example a request containing a day and year but no month, a request containing a month bu not year.

Fixes #52252.
