For the past 6 years, WordPress has operated as an oEmbed consumer, allowing users to easily embed content from other sites. By adding oEmbed provider support, this allows any oEmbed consumer to embed posts from WordPress sites.
In addition to creating an oEmbed provider, WordPress' oEmbed consumer code has been enhanced to work with any site that provides oEmbed data (as long as it matches some strict security rules), and provides a preview from within the post editor.
For security, embeds appear within a sandboxed iframe - the iframe content is a template that can be styled or replaced entirely by the theme on the provider site.

* Move all tests to a new 'multisite/isUploadSpaceAvailable.php'
* Store original `blog_upload_space` values before the class is loaded.
* Restore these values after each test tear down to avoid pollution.
Commit to testing `is_upload_space_available()` itself by always filtering the amount of space used through `pre_get_space_used`. This allows us to sanely test without worrying about the local environment. In the future, we may be able to remove some of these tests as `get_upload_space_available()` tests are built out and reliable.

In 4.3 the widget controls were fully initialized up front along with the sidebar controls. The sidebar control depended (unnecessarily) on the widget control to ensure that `wp.customize.Widgets.savedWidgetIds` was defined. So after [34563] there could be a situation where the widgets are added/removed from a sidebar before their controls are initialized (if the sidebar section is never expanded), resulting in an error attempting to get a property off of an undefined value. So this change does the right thing and defines `savedWidgetIds` up front.
Also changes the `savedWidgetIds` variable type from an array to an object, to match how it is used as a dictionary lookup.

The `WP_INSTALLING` constant is a flag that WordPress sets in a number of
places, telling the system that options should be fetched directly from the
database instead of from the cache, that WP should not ping wordpress.org for
updates, that the normal "not installed" checks should be bypassed, and so on.
A constant is generally necessary for this purpose, because the flag is
typically set before the WP bootstrap, meaning that WP functions are not yet
available. However, it is possible - notably, during `wpmu_create_blog()` -
for the "installing" flag to be set after WP has already loaded. In these
cases, `WP_INSTALLING` would be set for the remainder of the process, since
there's no way to change a constant once it's defined. This, in turn, polluted
later function calls that ought to have been outside the scope of site
creation, particularly the non-caching of option data. The problem was
particularly evident in the case of the automated tests, where `WP_INSTALLING`
was set the first time a site was created, and remained set for the rest of the
suite.
The new `wp_installing()` function allows developers to fetch the current
installation status (when called without any arguments) or to set the
installation status (when called with a boolean `true` or `false`). Use of
the `WP_INSTALLING` constant is still supported; `wp_installing()` will default
to `true` if the constant is defined during the bootstrap.

`wp_insert_term()` doesn't allow the creation of a term when the term `name`
is the same as another term in the same hierarchy level of the same taxonomy.
Previously, this duplicate check used `get_term_by( 'name' )`, which uses the
database collation to determine sameness. But common collations do not
distinguish between accented and non-accented versions of a character. As a
result, it was impossible to create a term 'Foo' if a sibling term with an
accented character existed.
We address this problem by using `get_terms()` to do the duplicate check. This
query returns all potentially matching terms. We then do a stricter check
for equivalence in PHP, before determining whether one of the matches is
indeed a duplicate.

After [33807], `Tests_Image_Intermediate_Size::test_get_intermediate_sizes_by_array_zero_width()`
was failing intermittently. This failure was due to the use of a random number
for the image height. When the height was sufficiently large - $height >= 202 -
to change the aspect ratio of the cropped image (based on WP's threshold of a
1px difference), the test passed. And when the height was exactly 200, the
medium image size was hit exactly. The failure occurred only with a height of
201, which is close enough to 200 so that WP determined that the aspect ratio
of the potential crop was close enough to match.

The call to `flock()` is an exclusive advisory lock, which in my testing only PHP respects (apache continues to read it).
Not all filesystems support locking (remote NFS mounts for example) so this offers minimal benefit to those platforms, but offers much better protection against file corruption on systems which do support it.
The call is blocking, so a second process will wait for the first to complete before writing if supported.

After [34561], `wp_list_comments()` no longer passed all of a post's comments
to `Walker_Comments`. As a result, calls to `get_comment_link()` occurring
inside the comment loop had insufficient context to determine the proper
'cpage' value to use when generating comment permalinks. This, in turn, caused
comment permalinks to behave erratically.
The current changeset addresses the problem as follows:
* `get_comment_link()` now accepts a 'cpage' parameter. When present, 'cpage' will be used to build the comment permalink - no automatic calculation will take place.
* When called within the main loop, `wp_list_comments()` calculates the proper 'cpage' value for comments in the loop, and passes it down to `get_comment_link()`.
* `cpage` and `comment-page-x` query vars are generally required in comment permalinks (see #34068), but an exception is made when 'default_comment_page=oldest': the bare post permalink will always be the same as `cpage=1`, so `cpage` is excluded in this case.

[34561] "fixed" the problem of newest-first comments showing fewer than
'per_page' comments on the post permalink when the total number of comments
was not divisible by 'per_page'. See #29462. But this fix caused numerous
other problems. First, comment pages reported by `get_page_of_comment()`
(which expects comment pages to be filled oldest-first) were no longer correct.
Second, and more seriously, the new logic caused comments to be shifted
between pages, making their permalinks non-permanent.
The current changeset reverts the changed behavior. In order to preserve the
performance improvements introduced in [34561], an additional query must be
performed when 'default_comments_page=newest' and 'cpage=0' (ie, you're viewing
the post permalink). A nice side effect of this revert is that we no longer
need the hacks required to determine proper comment pagination, introduced in
[34561].

Add 2 methods to `WP_List_Table`, `->get_orderby()` and `->get_order()`. Override the methods in `WP_Posts_List_Table`.
`WP_Posts_List_Table` calls `wp_edit_posts_query()` in `->prepare_items()` which is a wrapper for `wp()`. As such, we can obtain `orderby` and `order` via `get_query_var()`, instead of the URL.

[34718] introduced a 'db_version' check to term meta functions, to ensure that
they don't run when the term meta schema is not yet in place. This call to
`get_option()` causes a database hit during Multisite tests, due to the
presence of the `WP_INSTALLING` constant. See #31130. The extra database
queries are causing cache tests to fail.
In similar cases, we have `markTestSkipped()` when `is_multisite()`. Because
the term meta API is so extensive - term meta caches can be primed anywhere a
`WP_Query` loop is fired up - we implement a more generous workaround in this
case. To prevent `get_option( 'db_version' )` from hitting the database during
multisite unit tests, we use a 'pre_option_' filter.
Heaven help us.

The tests included in [34669] contained a couple of problems:
* Comments were not always created in the expected order, due to the incorrect use of 'comment_date_gmt'.
* 'asc'/'desc' and 'older'/'newer' were confused.
* 'default_comments_page=newest' ('last') didn't properly account for the cpage=1 offset.

Previously there were two persistent "View Post" links on an edit screen: next to the permalink and in the toolbar. This would then become three links after a post was published or updated, as a link is also included in the admin notice. This is a lot of redundancy and visual noise for a flow that is not your primary action upon starting to edit a post. The "View Post" link next to the sample permalink was particularly bad because it is styled like a button, but unlike a button, does not keep you on the current screen.
Because the permalink is now linked, there is no highlighted slug that you can click to edit, but rather just the "Edit" button.

When passing a value of 'slug' to `wp_insert_term()` that contains non-ASCII
characters, WordPress converts accented characters to non-accented versions.
(See `sanitize_title()` and `remove_accents()`.) The same conversion happens
when fetching when fetching a term using a slug. In this way, it's possible to
create a term and fetch it using the same accented string, even though the slug
is actually stored with non-accented characters.

[34583] modified comment queries so that all post fields are no longer loaded
by default. Instead, they are loaded only when requested on individual comment
objects. This changeset improves that flow:
* `WP_Comment` magic methods `__isset()` and `__get()` should only load the post when a post field is being requested.
* The new `update_comment_post_cache` argument for `WP_Comment_Query` allows developers to specify that, when comments are queried, all of the posts matching those comments should be loaded into cache with a single DB hit. This parameter defaults to false, since typical comment queries are linked to a single post.

The Menu Customizer feature includes a performance technique whereby the controls for nav menu items are only embedded into the DOM once the containing menu section is expanded. This commit implements the same DOM deferral for widgets but goes a step further than just embedding the controls once the widget area's Customizer section is expanded: it also defers the embedding of the widget control's form until the widget is expanded, at which point the `widget-added` event also fires to allow any additional widget initialization to be done. The deferred DOM embedding can speed up initial load time by 10x or more. This DOM deferral also yields a reduction in overall memory usage in the browser process.
Includes changes to `wp_widget_control()` to facilitate separating out the widget form from the surrounding accordion container; also includes unit tests for this previously-untested function. Also included are initial QUnit tests (finally) for widgets in the Customizer.

Previously, the 'page_comments' toggle allowed users to disable comment
pagination. This toggle was only superficial, however. Even with
'page_comments' turned on, `comments_template()` loaded all of a post's
comments into memory, and passed them to `wp_list_comments()` and
`Walker_Comment`, the latter of which produced markup for only the
current page of comments. In other words, it was possible to enable
'page_comments', thereby showing only a subset of a post's comments on a given
page, but all comments continued to be loaded in the background. This technique
scaled poorly. Posts with hundreds or thousands of comments would load slowly,
or not at all, even when the 'comments_per_page' setting was set to a
reasonable number.
Recent changesets have addressed this problem through more efficient tree-
walking, better descendant caching, and more selective queries for top-level
post comments. The current changeset completes the project by addressing the
root issue: that loading a post causes all of its comments to be loaded too.
Here's the breakdown:
* Comment pagination is now forced. Setting 'page_comments' to false leads to evil things when you have many comments. If you want to avoid pagination, set 'comments_per_page' to something high.
* The 'page_comments' setting has been expunged from options-discussion.php, and from places in the codebase where it was referenced. For plugins relying on 'page_comments', we now force the value to `true` with a `pre_option` filter.
* `comments_template()` now queries for an appropriately small number of comments. Usually, this means the `comments_per_page` value.
* To preserve the current (odd) behavior for comment pagination links, some unholy hacks have been inserted into `comments_template()`. The ugliness is insulated in this function for backward compatibility and to minimize collateral damage. A side-effect is that, for certain settings of 'default_comments_page', up to 2x the value of `comments_per_page` might be fetched at a time.
* In support of these changes, a `$format` parameter has been added to `WP_Comment::get_children()`. This param allows you to request a flattened array of comment children, suitable for feeding into `Walker_Comment`.
* `WP_Query` loops are now informed about total available comment counts and comment pages by the `WP_Comment_Query` (`found_comments`, `max_num_pages`), instead of by `Walker_Comment`.
Aside from radical performance improvements in the case of a post with many
comments, this changeset fixes a bug that caused the first page of comments to
be partial (`found_comments` % `comments_per_page`), rather than the last, as
you'd expect.

Shortlinks had their day in the popular usage sun before all these services moved to their own shorteners and running your own custom one became a lot easier. Shortlinks are still useful in some contexts, such as analytics or when links need to be shared verbally or copied down by hand.
If any filters are hooked onto `pre_get_shortlink` or `get_shortlink` and produce a non-empty value (with an exception described below), the button will magically reappear. This allows any custom shortlinks to keep the button without hiccups.
If you're in need of the default shortlinks, the fastest way to reenable them is `add_filter( 'pre_get_shortlink', '__return_false' )`. Note that it must return false in order to continue on to the rest of `wp_get_shortlink()`.
