Changeset 42773 for trunk/src/wp-admin/includes/file.php

Timestamp:

Message:

Filesystem API: Allow download_url() to return the response code and body on error as an additional WP_Error object data.

The error response body size is limited to 1 KB by default to avoid taking up too much memory. The size can be increased using download_url_error_max_body_size filter.

Props soulseekah, campusboy1987, mihdan, SergeyBiryukov.
Fixes #43329.
