WordPress 3.2 introduced several enhancements to the `copy_dir()` function:
* No more re-installing Akismet upon upgrade.
* Respect custom `WP_CONTENT_DIR` for bundled plugins/theme installation.
* Respect custom `WP_CONTENT_DIR`/`WP_LANG_DIR` for language files when upgrading.
* Add an exclusion list to `copy_dir()` as well as `WP_Filesystem_Base::wp_lang_dir()`.
* Standardize `WP_Filesystem` path method returns.
However, the version of `copy_dir()` that runs during the upgrade process is the one from the older install, not the newer, which means that these enhancements would only be available after upgrading to WordPress 3.2 first, e.g. in a subsequent upgrade to WordPress 3.3.
In order to make these enhancements immediately available in WordPress 3.2, specifically to take advantage of skip lists and avoid re-installing Akismet if it was previously deleted, a temporary copy of the function was utilized, with the intention to remove it in WordPress 3.3 or a later release.
With further enhancements made to the Upgrade API to support partial and no-content builds, this temporary copy is no longer relevant and can be safely removed.

Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.
There are a number of ways to mitigate this:
* If it is an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in.
* For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.
Trac ticket #56034 is open to investigate and handle the third and fourth type of situations, however it has become clear this will need more time and will not be ready in time for WP 6.1.
To reduce “noise” in the meantime, both in the error logs of WP users moving onto PHP 8.2, in the test run logs of WP itself, in test runs of plugins and themes, as well as to prevent duplicate tickets from being opened for the same issue, this commit adds the `#[AllowDynamicProperties]` attribute to all “parent” classes in WP.
The logic used for this commit is as follows:
* If a class already has the attribute: no action needed.
* If a class does not `extend`: add the attribute.
* If a class does `extend`:
- If it extends `stdClass`: no action needed (as `stdClass` supports dynamic properties).
- If it extends a PHP native class: add the attribute.
- If it extends a class from one of WP's external dependencies: add the attribute.
* In all other cases: no action — the attribute should not be needed as child classes inherit from the parent.
Whether or not a class contains magic methods has not been taken into account, as a review of the currently existing magic methods has shown that those are generally not sturdy enough and often even set dynamic properties (which they should not). See the [https://www.youtube.com/watch?v=vDZWepDQQVE live stream from August 16, 2022] for more details.
This commit only affects classes in the `src` directory of WordPress core.
* Tests should not get this attribute, but should be fixed to not use dynamic properties instead. Patches for this are already being committed under ticket #56033.
* While a number bundled themes (2014, 2019, 2020, 2021) contain classes, they are not a part of this commit and may be updated separately.

The existing filter `image_editor_output_format` receives an additional parameter `$size_name` which is populated whenever it controls the output format for a specific registered image size to create. Otherwise, it remains empty. In order to achieve this, a low level change has been added in bringing a new `$size_name` class property to the `WP_Image_Editor` base class, which is introduced in a backward compatible way that will not cause conflicts with custom implementations.
This parameter is then used in new logic inside the `wp_default_image_output_mapping()` callback function for the filter, controlling whether `image/jpeg` should map to `image/webp` output or not. By default, this is enabled for all WordPress core image sizes by default, and this list can be modified using a new `wp_image_sizes_with_additional_mime_type_support` filter, e.g. to remove core sizes or add custom sizes.
The customization per image size may be further enhanced by providing a more declarative API via a new parameter on the `add_image_size()` function.

In [53164] the `clipboard.js` library was updated to from version 2.0.8 to 2.0.10, and in doing so caused a TypeError JavaScript error to be thrown when the copy button for debug information was used.
With the update, the `clipboard.js` library introduced an enhancement to its `.copy()` API, which now removes the fake DOM element used for copying content, which Site Health previously had to remove manually.
As this fake DOM element is now removed automatically, the copy function within the debug information screen can rely on the library performing the removal, instead of WordPress needing to do so manually.

This changeset adds a new `page_cache` check which determines whether the site uses a full page cache, and in addition assesses the server response time. If no page cache is present and the server response time is slow, the check will suggest use of a page cache.
A few filters are included for customization of the check:
* `site_status_good_response_time_threshold` filters the number of milliseconds below which the server response time is considered good. The default value is based on the `server-response-time` Lighthouse audit and can be altered using this filter.
* `site_status_page_cache_supported_cache_headers` filters the map of supported cache headers and their callback to determine whether it was a cache hit. The default list includes commonly used cache headers, and it is filterable to support e.g. additional cache headers used by specific vendors.

A few filters are included for customization of the check, aimed primarily at hosting providers to provide more specific information in regards to their environment:
* `site_status_persistent_object_cache_url` filters the URL to learn more about object caching, so that e.g. a hosting-specific object caching support resource could be linked.
* `site_status_persistent_object_cache_notes` filters the notes added to the check description, so that more fine tuned information on object caching based on the environment can be provided.
* `site_status_should_suggest_persistent_object_cache` is a short-circuit filter which allows using entirely custom logic to determine whether a persistent object cache would make sense for the site.
* `site_status_persistent_object_cache_thresholds` filters the thresholds in the default logic to determine whether a persistent object cache would make sense for the site, which is based on the amount of data in the database.

The Site Health Status screen groups issues into the categories `good`, `recommended`, and `critical` when displaying them to the end user.
Initially, this screen would show `0 critical issues` while the checks were being performed, and then hide the group if no issues were discovered after all checks had completed, this not being an ideal user experience, as it is a better experience to show areas that have content, instead of hiding them after the fact.
This change makes the groups hidden by default, and also changes the logic to see if a group should be displayed when an item is added to the list (as opposed to the previous approach which only did this check once every single test had completed).

MySQL 8.0.17 deprecated the display width attribute for integer data types:
> As of MySQL 8.0.17, the `ZEROFILL` attribute is deprecated for numeric data types, as is the display width attribute for integer data types. You should expect support for `ZEROFILL` and display widths for integer data types to be removed in a future version of MySQL. Consider using an alternative means of producing the effect of these attributes. For example, applications can use the `LPAD()` function to zero-pad numbers up to the desired width, or they can store the formatted numbers in `CHAR` columns.
In practice, this means that display width is removed for integer types when creating a table:
* `BIGINT(20)` → `BIGINT`
* `INT(11)` → `INT`
* `MEDIUMINT(9)` → `MEDIUMINT`
* `SMALLINT(6)` → `SMALLINT`
* `TINYINT(4)` → `TINYINT`
Note: This only applies specifically to MySQL 8.0.17 or later. In MariaDB, display width for integer types is still available and expected.
This commit ensures that `dbDelta()`, which relies on the `DESCRIBE` SQL command to get the existing table structure and field types, when running on MySQL 8.0.17 or later, does not unnecessarily attempt to convert `BIGINT` fields back to `BIGINT(20)`, `INT` back to `INT(11)`, etc. When comparing the field type in the query with the existing field type, if display width is the only difference, it can be safely ignored to match MySQL behavior.
The change is covered by existing `dbDelta()` unit tests:
* A test for not altering `wp_get_db_schema()` queries on an existing install using MySQL 8.0.17+ now passes.
* More than twenty tests which previously failed on PHP 8.0.x + MariaDB due to incorrect expectations, caused by MariaDB version reporting not being consistent between PHP versions, now pass.

This only worked most of the time due to many FTP servers being permissive and allowing to execute `NLST` on files, which cannot be guaranteed and appears to not be the case in newer versions of Pure-FTPd (1.0.48 or later).
With a recent change in [53860], both methods were updated for compatibility with RFC 959:
* Both methods check if the path is a directory that can be changed into (and therefore exists).
* `WP_Filesystem_FTPext` uses `ftp_rawlist()` (FTP `LIST` command) to check for file existence.
* `WP_Filesystem_ftpsockets` uses file size to check for file existence.

WordPress FTP file checking was previously based upon `ftp_nlist()`. This function can be problematic at scale with a directory containing a large number of files. The same issue occurred using it with ftpsockets.
This changeset rewrites the FTP `exists()` functions to utilize a more efficient and stable check.
