In [38625], the functionality to search for attachments by filename was added
via the `posts_clauses` filter and the `_filter_query_attachment_filenames()`
function. This moves `_filter_query_attachment_filenames()` from
`wp-admin/includes/post.php` to `wp-includes/post.php` so that it can be
applied in the same manner in the REST API media endpoint.

Featured image support means that attachments can now be imported. Media can be sideloaded from within theme or plugin directories. Like other posts, attachments are auto-drafts until customizer changes are published, and are not duplicated when they already exist in the customized state. Attachment IDs can be used for any number of purposes, much like post IDs. Twenty Seventeen now includes 3 images used as featured images to best showcase the multi-section homepage setup.
As featured image IDs are stored in post meta, it also made sense to add support for page templates. Twenty Seventeen does not include any such templates, but the functionality can be quite important for displaying themes to their best effect.

WordPress has supported custom page templates for over 12 years, allowing developers to create various layouts for specific pages.
While this feature is very helpful, it has always been limited to the 'page' post type and not was not available to other post types.
By opening up the page template functionality to all post types, we continue to improve the template hierarchy's flexibility.
In addition to the `Template Name` file header, the post types supported by a template can be specified using `Template Post Type: post, foo, bar`.
When at least one template exists for a post type, the 'Post Attributes' meta box will be displayed in the back end, without the need to add post type support for `'page-attributes'`. 'Post Attributes' can be customized per post type using the `'attributes'` label when registering a post type.

Fixes bug where an invalid Last-Modified value would be returned in feed requests for sites that had 0 items to return. Comment or post feeds will now return the current timestamp as the Last-Modified header value. Example: a request for the comments feed for a site without any comments.
Replaced use of the local static variable `$cache_lastcommentmodified` to store the modified date in `get_lastcommentmodified()` with the Object Cache API. The `get_lastcommentmodified()` function returns early if there is a cached value and returns `false` if there where no comments found. Introduced `_clear_modified_cache_on_transition_comment_status()` to flush the `lastcommentmodified` cache key when a comment enters or leaves approval status.

REST API endpoints for your WordPress content. These endpoints provide machine-readable external access to your WordPress site with a clear, standards-driven interface, allowing new and innovative apps for interacting with your site. These endpoints support all of the following:
- Posts: Read and write access to all post data, for all types of post-based data, including pages and media.
- Comments: Read and write access to all comment data. This includes pingbacks and trackbacks.
- Terms: Read and write access to all term data.
- Users: Read and write access to all user data. This includes public access to some data for post authors.
- Meta: Read and write access to metadata for posts, comments, terms, and users, on an opt-in basis from plugins.
- Settings: Read and write access to settings, on an opt-in basis from plugins and core. This enables API management of key site content values that are technically stored in options, such as site title and byline.
Love your REST API, WordPress! The infrastructure says, "Let's do lunch!" but the content API endpoints say, "You're paying!"

Previously, changing the post thumbnail of a published post in the edit screen
would immediately apply the change, rather than waiting for the post to be
saved before applying the update. This could lead to someone unintentionally
editing the post thumbnail on a published post, and made it impossible to
preview changes to post thumbnails on published posts before saving the change.
This introduces a new Ajax handler, `wp_ajax_get_post_thumbnail_html()` to
retrieve the HTML for the post thumbnail meta box without updating the post
meta value for `_thumbnail_id`. It also allows post thumbnail changes to be
previewed by passing the `_thumbnail_id` as a query variable to the preview
screen and adding a new filter, `_wp_preview_post_thumbnail_filter()`, which
gets applied to `get_post_metadata` during the post preview process.

* `wp_get_attachment_caption` - Filters the value of `wp_get_attachment_caption()`.
* `the_post_thumbnail_caption` - Filters the display of the post thumbnail caption.
`the_post_thumbnail_caption()` is automatically filtered by `wptexturize()`,

When determining a unique post slug, trashed posts are taken into account. Previously, new posts would add suffixes to their slugs (e.g. `about-2`) when a post in the trash had the desired slug (e.g. `about`).
To avoid this behavior, when a post is trashed its slug (i.e. `post_name`) is now suffixed with `-%trashed%`. The post's pre-trash slug is stored as post meta, and if the post is restored from trash, its desired slug is reapplied.
For existing trashed posts which don't have the `-%trashed%` suffix, the suffix is added when a post with its desired slug is created.

Comment and term meta lazyloading for `WP_Query` loops, introduced in 4.4,
depended on filter callback methods belonging to `WP_Query` objects. This meant
storing `WP_Query` objects in the `$wp_filter` global (via `add_filter()`),
requiring that PHP retain the objects in memory, even when the local variables
would typically be expunged during normal garbage collection. In cases where a
large number of `WP_Query` objects were instantiated on a single pageload,
and/or where the contents of the `WP_Query` objects were quite large, serious
performance issues could result.
We skirt this problem by moving metadata lazyloading out of `WP_Query`. The
new `WP_Metadata_Lazyloader` class acts as a lazyload queue. Query instances
register items whose metadata should be lazyloaded - such as post terms, or
comments - and a `WP_Metadata_Lazyloader` method will intercept comment and
term meta requests to perform the cache priming. Since `WP_Metadata_Lazyloader`
instances are far smaller than `WP_Query` (containing only object IDs), and
clean up after themselves far better than the previous `WP_Query` methods (bp
only running their callbacks a single time for a given set of queued objects),
the resource use is decreased dramatically.

When a custom post type item is not viewable on the front end, we don't want to show links to View it (on the front end) all over the admin. We also want to hide the Preview link, et al. We also want our admin messages to not contain said links.
Custom post types with `public_queryable` set to `false` are not viewable on the front end.
`'page'` is viewable on the front end, but `'page'` is a `_builtin` type, and `public_queryable` is set to `false` when it is registered - see `WP::parse_request()` for when `public_queryable` gets used.
This is confusing, but also somewhat straightforward: to determine if a post type is viewable on the front end, we can check one way for `_builtin => true` and another way for `_builtin => false`:
`$post_type->publicly_queryable || ( $post_type->_builtin && $post_type->public )`
If a post type is `publicly_queryable`, it's viewable. If that value is `false`, it is viewable if it's a `_builtin` type that is also `public`.

On certain permalink structures, a numeric post slug will result in a post
permalink that conflicts with a date archive URL. For example, with permastruct
`/%year%/%monthnum%/%postname%/`, a post published in May 2015 with slug
`'15'` will result in a URL (`/2015/05/15/`) that conflicts with the archive
for May 15, 2015.
To avoid this problem, `wp_unique_post_slug()` rejects a requested slug when it
would generate a conflict of this type. Thus, in our example, `'15'` would

`wp_get_attachment_url()`, via `wp_upload_dir()`, uses 'siteurl' to generate
attachment URLs. When a site is SSL-optional on the front end - ie, 'siteurl'
is non-HTTPS, but SSL is available - a number of situations can arise where
non-HTTPS attachment URLs cause browser mixed-content warnings:
a) SSL is forced in the admin and `wp_get_attachment_url()` is used to generate the `<img>` tag for an inserted image. In these cases, the post content will contain non-HTTPS. Viewing/editing this post in the Dashboard will result in non-HTTPS images being served in an SSL environment.
b) `wp_get_attachment_url()` is used in a theme to generate an `<img>` `src` attribute on a public page. When viewing that page over SSL, the images will have HTTP URLs.
This changeset switches attachment URLs to HTTPS when it's determined that the
host supports SSL. This happens when 'siteurl' is non-SSL, but the current page
request *is* over SSL, and the host of the current request matches the host of
the URL being generated.

In some cases, the values of `$old_status` and `$new_status` may be the same thing before and after a post status is "transitioned". An example of this would be the scenario where a published post is being updated: the status before and after the update both equal 'publish'.
Further, the documentation clarifies that if the intent is to only execute code when initially transitioningto a post status from something else, the 'transition_post_status' hook should be used instead of one of the dynamic hooks to avoid confusion.

Per our inline documentation standards, no further use of the `@uses` tag is recommended as used and used-by relationships can be derived through other means. This removes most uses of the tag in core documentation, with remaining tags to be converted to `@global` or `@see` as they apply.
Fixes#30191.

* Check `! empty( $postarr['file'] )` before calling `update_attached_file()`
* Add a unit test: `test_update_attachment_fields()`
* Run the same logic for empty `guid` for attachments that always ran in `wp_insert_post()`, as per #18310. This fixes a unit test that would have broken when this ticket was marked closed.
* Updated the unit test in `Tests_Media::test_wp_prepare_attachment_for_js()` to account for `url` no longer being empty

* `edit_post_{$field}` pairs with `edit_{$field}`
* `pre_post_{$field}` pairs with `pre_{$field}`
* `post_{$field}` pairs with `{$field}`
As the above pairs' docs are unnecessarily duplicative, the second sets of docs have been removed. Also, the "duplicates" are purposely not marked as such in this case as the hook names differ. Also remove `@deprecated` tags mistakenly left in in [28041].

Both of these icons can be colored to match the color scheme, including hover states.
Both are accepted for register_post_type()'s menu_icon argument, and also add_menu_page()'s $icon_url argument.
To use a Dashicon, pass the name of the helper class, e.g. 'dashicons-piechart'.
To use an SVG, pass a valid data URI string starting with 'data:image/svg+xml;base64,'.

Hierarchical rewrite rules operate via the 'pagename' query variable which is
passed to get_page_by_path(). However, the current rewrite rules use the 'name'
query variable for hierarchical types without a custom query_var.
