| 70 | * Display-only blocks whose registration PHP can be deferred until the block |
| 71 | * actually appears on a front-end page. |
| 72 | * |
| 73 | * Every block listed here has been verified to be "pure": the callback it hooks |
| 74 | * to `init` does nothing but call Blocks::jetpack_register_block() (plus trivial |
| 75 | * connection/module guards). It registers exactly one block type named |
| 76 | * `jetpack/<dir>` (matching its directory), and any front-end hooks it adds (asset |
| 77 | * enqueues, wp_footer, filters, …) live inside its render callback, so they only |
| 78 | * run when the block is rendered. |
| 79 | * |
| 80 | * On plain front-end requests these blocks are NOT loaded on `init`. Instead they |
| 81 | * are registered just-in-time the first time the block (or a block whose subtree |
| 82 | * contains it) is encountered while rendering, via self::lazy_register_deferred_block() |
| 83 | * on `pre_render_block`. On admin/REST/cron/CLI/XML-RPC (block-editor) requests they |
| 84 | * keep loading eagerly so the editor, the block-types REST endpoint and server-side |
| 85 | * rendering are unaffected. |
| 86 | * |
| 87 | * A block must NOT be added here if: |
| 88 | * - its `init` callback registers any other hook, post meta, REST route, |
| 89 | * shortcode, block pattern or hooked-block; |
| 90 | * - it registers more than one block type, or a block name that differs from its |
| 91 | * directory name (e.g. videopress registers `jetpack/videopress-block`); or |
| 92 | * - it uses `plan_check` (its availability is computed from the init-time |
| 93 | * `jetpack_register_gutenberg_extensions` hook, which lazy registration bypasses, |
| 94 | * so the front-end availability nudge/render could read a stale value); or |
| 95 | * - a front-end path reads its entry from get_cached_availability() before the |
| 96 | * block renders. Deferred blocks appear unavailable there until the lazy |
| 97 | * registration callback runs; or |
| 98 | * - its block file can be `require`d by another runtime code path after `init` |
| 99 | * (e.g. slideshow is included by modules/shortcodes/slideshow.php). The lazy |
| 100 | * loader registers a block by running the `init` callback its include adds; if |
| 101 | * the file was already included elsewhere, the include is a no-op and the |
| 102 | * callback would never run, so the block would silently fail to register; or |
| 103 | * - another runtime code path calls a function defined in its block file |
| 104 | * (e.g. button defines Button\render_email(), called by subscriptions and |
| 105 | * memberships for WooCommerce e-mail rendering). Deferring the file would leave |
| 106 | * that function undefined when the dependent path runs; or |
| 107 | * - it registers a `render_email_callback`. That callback is read off the |
| 108 | * registered block type by the WooCommerce e-mail editor — an out-of-band |
| 109 | * renderer that does not go through `pre_render_block`/`do_blocks` — so the block |
| 110 | * must already be registered when an e-mail containing it is rendered, which can |
| 111 | * happen on a front-end request (e.g. a transactional e-mail sent during checkout). |
| 112 | * |
| 113 | * When in doubt, leave it out: omitted blocks simply keep their current eager |
| 114 | * behavior. |
