Bernhard Reiter 020fde0d1d Block Hooks: `apply_block_hooks_to_content` in Patterns, Templates.
In the Patterns registry, use `apply_block_hooks_to_content` (introduced in [58291])  instead of the `WP_Block_Patterns_Registry` class's private `get_content` method. (The latter is removed as part of this changeset.)

In a similar vein, use `apply_block_hooks_to_content` in the `_build_block_template_result_from_file` and `_build_block_template_result_from_post` functions, respectively.

For that to work, `apply_block_hooks_to_content` is amended to inject the `theme` attribute into Template Part blocks, even if no hooked blocks are present.

This kind of centralization is required as a preparation for #61902.

Props bernhard-reiter, jonsurrell.

noisysocks ef2b22c001 Editor: Add plugin template registration API and improve theme overrides for plugin-registered templates
This commit introduces a new API to allow plugins to easily register block
templates with `wp_register_block_template()` and the
`WP_Block_Templates_Registry` class, addressing the complexity of hooking into
multiple filters. It also ensures plugin-registered templates overridden by
themes fall back to the plugin-provided title and description when the theme
doesn't define them.

Bernhard Reiter 4cecd0e731 Block Hooks: Don't erase post content if it isn't changed by client.
The `inject_ignored_hooked_blocks_metadata_attributes` filter that is attached to both the `rest_pre_insert_wp_template` and `rest_pre_insert_wp_template_part` hooks receives a `stdClass` object from the Templates REST API controller that contains all fields that the client would like to modify when making a `POST` request (plus the `id` to identify the relevant template or template part, respectively).

There are cases when the `post_content` field is not set, e.g. when the client would like to rename an existing template (in which case it would only set the `title` field).

Prior to this changeset, the filter would erroneously apply the Block Hooks algorithm to the non-existent `post_content` field regardless, which would result in it being set to the empty string `''`. As a consequence, renaming a template would have the unwanted side effect of wiping its contents.

This changeset fixes the issue by returning early from the filter if the `post_content` field is not set.

Bernhard Reiter 73b9a4956f Block Hooks: Allow child insertion into Template Part block.
The Block Hooks mechanism was previously extended to allow insertion of a block as a Navigation block's first or last child. This was implemented by storing the `ignoredHookedBlocks` array in the corresponding `wp_navigation` post's post meta (instead of a metadata attribute on the anchor block).

This changeset extends that mechanism to Template Part blocks, by storing said metadata in the corresponding `wp_template_part` post's post meta, thus allowing extenders to use Block Hooks to insert a block as a Template Part block's first or last child, respectively.

Replaces `trigger_error()` with `wp_trigger_error()`.

The usage of `wp_trigger_error()` avoids generating `E_USER` family errors unless `WP_DEBUG` is on. In doing so, users should not see these messages in normal production.

Notes:
* Removes `E_USER_NOTICE` when passed as an argumnent, as it's the default error level.
* An empty string is passed for the function name when its name is already in the error message or does not add value to the error message.
* Externally maintained libraries are not included.

Bernhard Reiter b62b7a599e Block Hooks: Move ignoredHookedBlocks metadata injection logic.
As of [57790], the Templates endpoint uses the `rest_pre_insert_*` filter to inject the `ignoredHookedBlocks` metadata attribute into anchor blocks, prior to persisting a template or template part to the database. The same principle was implemented for the Navigation endpoint (where additionally, first and last child blocks added at the top level are store in the `wp_navigation` post object's post meta). The required logic was added to the Navigation block's code, i.e. inside the Gutenberg code repository, and then synchronized to Core.

In order to harmonize the code between the two endpoints, this changeset introduces a new `update_ignored_hooked_blocks_postmeta` function, which is based on the Navigation block's `block_core_navigation_update_ignore_hooked_blocks_meta`, alongside a few helper functions, and hooks it to the `rest_pre_insert_wp_navigation` filter hook. (The Navigation block has been prepared in [58275] to add an additional conditional to check for the new `update_ignored_hooked_blocks_postmeta` filter so there won't be any collisions.)

Eventually, this will allow to deprecate `block_core_navigation_update_ignore_hooked_blocks_meta` (and some related functions), and remove the relevant code from the Navigation block. It also paves the way for some other future changes, such as inserting a hooked block as a Template Part block's first or last child (#60854).

Bernhard Reiter 031dbe0b4d Block Hooks API: Insert metadata at the same time as hooked blocks.
The Block Hooks UI relies on the `ignoredHookedBlocks` metadata when determining whether to show the toggle in the Site Editor. The problem is that for uncustomized templates we don't add this metadata.

Currently the visitor functions have a default callback of `insert_hooked_blocks` and we only add the metadata when we're writing to the database via an available filter in the template controller.

This changeset creates a new callback which both inserts the hooked blocks and adds the `ignoredHookedBlocks` metadata to the anchor block, and uses this new callback explicitly in the visitor functions that are run upon reading from the database.

We continue to set the `ignoredHookedBlocks` metadata when writing to the database, i.e. this operation happens twice. Although not ideal, this is necessary to cover the following scenarios:

* When the user adds an anchor block within the editor, we still need to add the `ignoredHookedBlocks` meta to it to prevent hooked blocks hooking on to it unexpectedly on the frontend. This is required to keep parity between the frontend and editor.
* When a user writes template data to the database directly through the API (instead of the editor), we need to again ensure we're not inserting hooked blocks unexpectedly.

It is worth noting that with this change, the first hooked block to insert relative to its anchor block will be accepted. Any additional blocks of the same type (e.g. a second `core/loginout` block) trying to hook onto the same anchor block will be ignored, irrespective of the position.

Bernhard Reiter 725f302121 Block Hooks: Pass correct context to filters.
The `$context` argument passed to filters such as `hooked_block_types`, `hooked_block`, and `hooked_block_{$hooked_block_type}` allows them to conditionally insert a hooked block. If the anchor block is contained in a template or template part, `$context` will be set to a `WP_Block_Template` object reflecting that template or part.

The aforementioned filters are applied when hooked block insertion is run upon reading a template (or part) from the DB (and before sending the template/part content with hooked blocks inserted over the REST API to the client), but also upon writing to the DB, as that's when the `ignoredHookedBlocks` metadata attribute is set.

Prior to this changeset, the `$context` passed to Block Hooks related filters in the latter case reflected the template/part that was already stored in the database (if any), which is a bug; instead, it needs to reflect the template/part that will result from the incoming `POST` network request that will trigger a database update.

Those incoming changes are encapsulated in the `$changes` argument passed to the `reset_pre_insert_template` and  `reset_pre_insert_template_part` filters, respectively, and thus to the `inject_ignored_hooked_blocks_metadata_attributes` function that is hooked to them. `$changes` is of type `stdClass` and only contains the fields that need to be updated. That means that in order to create a `WP_Block_Template` object, a two-step process is needed:

- Emulate what the updated `wp_template` or `wp_template_part` post object in the database will look like by merging `$changes` on top of the existing `$post` object fetched from the DB, or from the theme's block template (part) file, if any.
- Create a `WP_Block_Template` from the resulting object.

To achieve the latter, a new helper method (`_build_block_template_object_from_post_object`) is extracted from the existing `_build_block_template_result_from_post` function. (The latter cannot be used directly as it includes a few database calls that will fail if no post object for the template has existed yet in the database.)

While somewhat complicated to implement, the overall change allows for better separation of concerns and isolation of entities. This is visible e.g. in the fact that `inject_ignored_hooked_blocks_metadata_attributes` no longer requires a `$request` argument, which is reflected by unit tests no longer needing to create a `$request` object to pass to it, thus decoupling the function from the templates endpoint controller.

Unit tests for `inject_ignored_hooked_blocks_metadata_attributes` have been moved to a new, separate file. Test coverage has been added such that now, all three relevant scenarios are covered:

- The template doesn't exist in the DB, nor is there a block theme template file for it.
- The template doesn't exist in the DB, but there is a block theme template file for it.
- The template already exists in the DB.

Those scenarios also correspond to the logical branching inside `WP_REST_Templates_Controller::prepare_item_for_database`, which is where `inject_ignored_hooked_blocks_metadata_attributes` gets its data from.

Bernhard Reiter 8648d06284 Block Hooks: Use new Templates Controller filter instead of action.
This changeset adds a new `rest_pre_insert_{$this->post_type}` filter in the `WP_REST_Templates_Controller`, where it is applied to the return value of the `prepare_item_for_database` method. (This is consistent with the `WP_REST_Post_Controller`, where that filter has existed before.)

The new filter is then used to inject hooked blocks into the template (or template part) content received via the endpoint, prior to persisting it to the database.

This supersedes the previous mechanism, which was using the `rest_after_insert_{$this->post_type}` ''action'', from which it performed an additional `wp_update_post` call to update the template (part) content with the hooked blocks injected. The new technique eschews that additional call and the resulting extra revision it created, as well as a problem with regard to duplicated escaping and sanitization, which had caused some special characters to be garbled.

Decouple hooked blocks insertion from setting the `metadata.ignoredHookedBlocks` attribute on anchor blocks, and perform the latter step upon saving a template or template part to the database. This ensures that anchor blocks that have been newly added to a template (or part) on the client side will also get `ignoredHookedBlocks` metadata set correctly, thus preserving editor/front-end parity.

Bernhard Reiter 382c01d848 Block Hooks: Expose serialized template content to filter.
The recently introduced Block Hooks API exposes a filter (`hooked_block_types`) which is given a `$context` argument, among others. If the filter is called on a block that's part of a template or template part, `$context` is set to the corresponding `WP_Block_Template` object.

However, that object's `$content` property is currently ''not'' exposed to the filter. This changeset amends that shortcoming.

This is useful for callbacks that might want to detect the presence of a serialized block instance (or potentially in the future utilize the HTML API) to restrict where the block is injected (before the template is rendered).

Addressing this also achieves parity with the structure of `$context` when it represents a pattern (where pattern serialized content is present).

Bernhard Reiter 8a7d30c7f8 Patterns: Don't inject `theme` attribute on frontend.
Having the patterns registry inject the `theme` attribute into all Template Part blocks inside every pattern was found to negatively impact performance. It turns out that it's only required for the editor (i.e. in the REST API) but not on the frontend; there, it's instead possible to fall back to the currently active theme.

The latter change was made to the Pattern and Template Part blocks in https://github.com/WordPress/gutenberg/pull/55217, which was sync'ed to Core in [56849]. Consequently, this changeset removes `theme` attribute insertion from the frontend.

spacedmonkey 6e774df98c REST API: Fix issue with Template and Template Part Revision/Autosave REST API controllers.
The Template and Template Part REST API controllers have unique characteristics compared to other post type REST API controllers. They do not rely on integer IDs to reference objects; instead, they use a combination of the theme name and slug of the template, like 'twentytwentyfour//home.' Consequently, when the post types template and template part were introduced in [52062], it led to the registration of REST API endpoints for autosaves and revisions with invalid URL structures.

In this commit, we introduce new functionality to enable custom autosave and revisions endpoints to be registered at the post type level. Similar to the 'rest_controller_class' parameter, developers can now define 'revisions_rest_controller' and 'autosave_rest_controller.' This empowers developers to create custom controllers for these functionalities. Additionally, we introduce a 'late_route_registration' parameter, which proves helpful when dealing with custom URL patterns and regex pattern matching issues.
This commit registers new classes for template and template part autosave and revisions controllers, differentiating them from standard controllers in the following ways:
* The response shape now matches that of the template controller.
* Permission checks align with the template controller.
* A custom URL pattern is introduced to support slug-based identification of templates.

Furthermore, we've updated the utility function '_build_block_template_result_from_post' to support passing revision post objects. This enhancement ensures compatibility with the custom revisions controller.

Bernhard Reiter fc229aa436 Blocks: Call `get_hooked_blocks` only once per template/part/pattern.
Prior to this changeset, `get_hooked_blocks` was called four times ''for every parsed block'' in each template, template part, and pattern. With this changeset applied, `get_hooked_blocks` is called only once per template, template part, or pattern.

Additionally, `get_hooked_blocks` is called only once when returning the list of all registered patterns. (The latter modification brings the implementation closer to its state prior to Block Hooks.)

Finally, when there are no registered hooked blocks or `hooked_block_types` filters, parsing, hooked block insertion, and re-serializing is skipped altogether.

Bernhard Reiter 6bf6244dc7 Blocks: Implement automatic block insertion into Block Hooks.
Block Hooks allow a third-party block to specify a position relative to a given block into which it will then be automatically inserted (e.g. a "Like" button block can ask to be inserted after the Post Content block, or an eCommerce shopping cart block can ask to be inserted after the Navigation block).

The underlying idea is to provide an extensibility mechanism for Block Themes, in analogy to WordPress' [https://developer.wordpress.org/plugins/hooks/ Hooks] concept that has allowed extending Classic Themes through filters and actions.

The two core tenets for Block Hooks are:

1. Insertion into the frontend should happen right after a plugin containing a hooked block is activated (i.e. the user isn't required to insert the block manually in the editor first); similarly, disabling the plugin should remove the hooked block from the frontend.
2. The user has the ultimate power to customize that automatic insertion: The hooked block is also visible in the editor, and the user's decision to persist, dismiss (i.e. remove), customize, or move it will be respected (and reflected on the frontend).

To account for both tenets, the **tradeoff** was made to limit automatic block insertion to unmodified templates (and template parts, respectively). The reason for this is that the simplest way of storing the information whether a block has been persisted to (or dismissed from) a given template (or part) is right in the template markup.

To accommodate for that tradeoff, [https://github.com/WordPress/gutenberg/pull/52969 UI controls (toggles)] are being added to increase visibility of hooked blocks, and to allow for their later insertion into templates (or parts) that already have been modified by the user.

For hooked blocks to appear both in the frontend and in the editor (see tenet number 2), they need to be inserted into both the frontend markup and the REST API (templates and patterns endpoints) equally. As a consequence, this means that automatic insertion couldn't (only) be implemented at block ''render'' stage, as for the editor, the ''serialized'' (but ''unrendered'') markup needs to be modified.

Furthermore, hooked blocks also have to be inserted into block patterns. Since practically no filters exist for the patterns registry, this has to be done in the registry's `get_registered` and `get_all_registered` methods.

Bernhard Reiter f6307ff5fc Blocks: Change `traverse_and_serialize_block(s)`'s callback signature.
During work on #59399, it was discovered that ''sibling'' block insertion wasn't likely going to work the way it was planned, which required devising an alternative solution. This new solution requires some changes to `traverse_and_serialize_block(s)`:

- Change the signature of the existing callback such that:
  - the return value is a string that will be prepended to the result of the inner block traversal and serialization;
  - the function arguments are: a ''reference'' to the current block (so it can be modified inline, which is important e.g. for `theme` attribute insertion), the parent block, and the previous block (instead of the block index and chunk index).
- Add a second callback argument to `traverse_and_serialize_block(s)`, which is called ''after'' the block is traversed and serialized.
  - Its function arguments are a reference to the current block, the parent block, and the next block.

spacedmonkey 8fdddd7b6d Themes: Improve performance of get_block_theme_folders function
This commit enhances the performance of the get_block_theme_folders function by introducing a new method called get_block_template_folders within the WP_Theme class. Previously, this function suffered from poor performance due to repeated file lookups using file_exists. The new method implements basic caching, storing the result in the theme's cache, similar to how block themes are cached in the block_theme property (see [55236]).

Additionally, this change improves error handling by checking if a theme exists before attempting to look up the file. It also enhances test coverage.

Bernhard Reiter 172397e6e5 Themes: Inject `theme` attribute during serialization.
Rather than using `_inject_theme_attribute_in_block_template_content` to inject the `theme` attribute into all Template Part blocks found in a given file-based Block Template, introduce a new function called `_inject_theme_attribute_in_template_part_block`, and use that as second argument to `serialize_blocks()` (introduced in [56557]) in order to inject said attribute during tree traversal for serialization.

This allows for a more modular approach that will eventually be extended to implement automatic insertion of hooked blocks.

Note that we're guarding `_build_block_template_result_from_file()` (i.e. the callsite of `_inject_theme_attribute_in_template_part_block` and previously of `_inject_theme_attribute_in_block_template_content`) against regressions through additional unit test coverage added in [56562].
