Batching a WP-CLI loop so it does not exhaust memory

NoteFebruary 28, 20172 min read

A command iterating every post accumulates objects in the query cache and the object cache, so a loop that works over 10,000 rows fails over 200,000 — and…

A persistent object cache changes what transients mean

NoteFebruary 22, 20171 min read

Without a drop-in, a transient is two rows in wp_options. With one, transients are stored in the object cache and never touch the database — which is faster…

rest_prepare_post to reshape a response

NoteFebruary 17, 20171 min read

Removing a field from a core endpoint, or renaming one, has no registration API — the filter on the prepared response is the only hook, and it runs…

Gutenberg is a plugin this year, and only a plugin

NoteJanuary 17, 20171 min read

The editor is under active development as a feature plugin, which means it can be installed, it changes weekly, and nothing about a site depends on it unless…

rest_api_init fires late, and registering early anyway

NoteDecember 21, 20162 min read

rest_api_init only fires on a REST request, which is efficient and means anything registered there does not exist during a normal page load — including the route definitions…

4.7 shipped the content endpoints. What moving off the feature plugin involves, why authentication is still the unsolved half, and the read API every site now exposes.

wp_remote_get returns an array or a WP_Error, never both

NoteDecember 19, 20162 min read

The HTTP API returns a response array on success and a WP_Error on failure, and the two share no shape at all — so any code that reaches…

WP_Error is not an exception and will not stop anything

NoteDecember 8, 20161 min read

WP_Error is a return value. Creating one has no effect on control flow, so a function that builds one and does not return it has done nothing at…

The shutdown hook runs after the response is sent

NoteNovember 18, 20161 min read

shutdown is the last action WordPress fires, and by then the output has already gone to the client — so it is the right place for bookkeeping and…

A transient with an expiry of zero never expires

NoteNovember 8, 20161 min read

Passing 0 as the expiry reads like “expire immediately” and means the opposite: no expiry is stored, so the transient lives until something deletes it. A variable that…
