2128238311 Bootstrap/Load: Check $_SERVER['SCRIPT_NAME'] exists before passing to strpos() in wp_fix_server_vars().
If `SCRIPT_NAME'` does not exist (which can happen in cron jobs), the following happens:

* PHP 8.1+:
    * `Warning: Undefined array key "SCRIPT_NAME"`
    * `Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated` 
* PHP 8.0: `Warning: Undefined array key "SCRIPT_NAME"`
* PHP 5.6-7.4: No warning or notice

This commit checks if the key exists before passing it to `strpos()`. This resolves the warning, notice, and future error.

d5f7417686 Bootstrap/Load: Add HTTP/3 as a valid HTTP protocol.
As of November 2021, the `HTTP/3` protocol is still officially an Internet Draft, but is already supported by 74% of running web browsers and, according to W3Techs, 23% of the top 10 million websites. It has been supported by Google Chrome (including Chrome for Android, and Microsoft Edge, which is based on it) since April 2020 and by Mozilla Firefox since May 2021. Safari 14 (on macOS Big Sur and iOS 14) has also implemented the protocol but support is hidden behind a feature flag.

Based on the wide support, this change adds `HTTP/3` as a valid HTTP protocol.

8b025acd61 Multisite: Log error/warnings/notices from ms-files.php.
Previously errors were not displayed or logged, but the original intention was only to prevent them from being displayed. Hiding them from logs makes problems like #53492 much harder to debug.

This makes the handling of errors in `ms-files` consistent with the REST API, `admin-ajax`, and XML-RPC.

926cd0afee Bootstrap/Load: Add Function for reliable timing data
Adds timer_float which can be used to get the time elapsed so far during the PHP script. Should make it easier to display the page generation time in the footer of admin.

WordPress should expose timing data as a float in the most accurate manner possible. timer_stop() has two problems: it uses an initial timestamp generated later than it needs to be and its formatted return value can not reliably be used as a number (some locales swap commas and periods, for example).

6a8a83ea09 App Passwords: Extract Basic Auth check into a reusable filterable function.
In [49752] a check was added to prevent creating new Application Passwords if Basic Auth credentials were detected to prevent conflicts. This check takes place in WP-Admin, though a conflict would only arise if Basic Auth was used on the website's front-end.

This commit extracts the Basic Auth check into a reusable function, `wp_is_site_protected_by_basic_auth()`, which can be adjusted using a filter of the same name. This way, a site that uses Basic Auth to protect WP-Admin can still use the Application Passwords feature.

In the future, instead of requiring the use of a filter, WordPress could make a loopback request and check for a `WWW-Authenticate` header to make this detection more robust out of the box.

5df8bf60aa REST API: Support a broader range of JSON media types.
Previously, we only supported `application/json` which prevented using subtypes like `application/activity+json`. This allows for the REST API to `json_decode` the body of requests using a JSON subtype `Content-Type`. Additionally, `wp_die()` now properly sends the error as JSON when a JSON subtype is specified in the `Accept` header.

d5ebe12f11 REST API: Introduce Application Passwords for API authentication.
In WordPress 4.4 the REST API was first introduced. A few releases later in WordPress 4.7, the Content API endpoints were added, paving the way for Gutenberg and countless in-site experiences. In the intervening years, numerous plugins have built on top of the REST API. Many developers shared a common frustration, the lack of external authentication to the REST API.

This commit introduces Application Passwords to allow users to connect to external applications to their WordPress website. Users can generate individual passwords for each application, allowing for easy revocation and activity monitoring. An authorization flow is introduced to make the connection flow simple for users and application developers.

Application Passwords uses Basic Authentication, and by default is only available over an SSL connection.

da19724be9 Bootstrap/Load: Remove the ability to alter the list of environment types in wp_get_environment_type().
The intention of `wp_get_environment_type()` is to provide a consistent means of identifying the environment type, not of identifying a specific environment.

Actual environments should fit within one of the existing types: `local`, `development`, `staging`, or `production`. That should cover the types that plugins and themes might be concerned about when toggling functionality.

f83c504b88 I18N: Remove the "Error:" prefix from error messages.
For a number of years, most of the WordPress error messages have been prefixed with "Error:". However, these messages appear in a context where it's already clear an error occurred. Whether it's an error, a warning, or any other classification, that's not so relevant for users. The content of the message is the relevant part. The "Error:" prefix doesn't add great value while it does add unnecessary complexity for the message readability.

Also, revises some of these messages to improve clarity and removes HTML from translatable strings.

d858656023 Bootstrap/Load: Make handling the /favicon.ico requests more flexible.
Previously, `wp_favicon_request()` was introduced in [13205] to avoid a performance hit of serving a full 404 page on every favicon request.

While working as intended, that implementation did not provide a way for theme or plugin authors to manage the behavior of favicon requests.

This changeset implements the following logic (only applied if WordPress is installed in the root directory):

* If there is a Site Icon set in Customizer, redirect `/favicon.ico` requests to that icon.
* Otherwise, use the WordPress logo as a default icon.
* If a physical `/favicon.ico` file exists, do nothing, let the server handle the request.

Handling `/favicon.ico` is now more consistent with handling `/robots.txt` requests.

New functions and hooks:

* Introduce `is_favicon()` conditional tag to complement `is_robots()`.
* Introduce `do_favicon` action to complement `do_robots` and use it in template loader.
* Introduce `do_favicon()` function, hooked to the above action by default, to complement `do_robots()`.
* Introduce `do_faviconico` action to complement `do_robotstxt`, for plugins to override the default behavior.
* Mark `wp_favicon_request()` as deprecated in favor of `do_favicon()`.

Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.

3a77265148 Bootstrap/Load: Introduce a recovery mode for fixing fatal errors.
Using the new fatal handler introduced in [44962], an email is sent to the admin when a fatal error occurs. This email includes a secret link to enter recovery mode. When clicked, the link will be validated and on success a cookie will be placed on the client, enabling recovery mode for that user. This functionality is executed early before plugins and themes are loaded, in order to be unaffected by potential fatal errors these might be causing.

When in recovery mode, broken plugins and themes will be paused for that client, so that they are able to access the admin backend despite of these errors. They are notified about the broken extensions and the errors caused, and can then decide whether they would like to temporarily deactivate the extension or fix the problem and resume the extension.

A link in the admin bar allows the client to exit recovery mode.

1e4088fc98 Bootstrap/Load: Introduce fatal error recovery mechanism allowing users to still log in to their admin dashboard.
This changeset introduces a `WP_Shutdown_Handler` class that detects fatal errors and which extension (plugin or theme) causes them. Such an error is then recorded, and an error message is displayed. Subsequently, in certain protected areas, for example the admin, the broken extension will be paused, ensuring that the website is still usable in the respective area. The major benefit is that this mechanism allows site owners to still log in to their website, to fix the problem by either disabling the extension or solving the bug and then resuming the extension.

Extensions are only paused in certain designated areas. The frontend for example stays unaffected, as it is impossible to know what pausing the extension would cause to be missing, so it might be preferrable to clearly see that the website is temporarily not accessible instead.

The fatal error recovery is especially important in scope of encouraging the switch to a maintained PHP version, as not necessarily every WordPress extension is compatible with all PHP versions. If problems occur now, non-technical site owners that do not have immediate access to the codebase are not locked out of their site and can at least temporarily solve the problem quickly.

Websites that have custom requirements in that regard can implement their own shutdown handler by adding a `shutdown-handler.php` drop-in that returns the handler instance to use, which must be based on a class that inherits `WP_Shutdown_Handler`. That handler will then be used in place of the default one.

Websites that would like to modify specifically the error template displayed in the frontend can add a `php-error.php` drop-in that works similarly to the existing `db-error.php` drop-in.

4b6b8a55fe Load: Disable PHP errors for JSON requests
Because WP REST API requests aren't identified until `parse_request`, it's impractical to reference the `REST_REQUEST` constant in `wp_debug_mode()`. Instead, it's more helpful to assume that a request wanting a JSON response probably doesn't want PHP errors breaking the response.

56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.

This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script. 
- Auto-fixable coding standards issues will now cause Travis failures.

Fixes #44600.

176a289050 Multisite: Introduce metadata for sites.
A new global multisite table `wp_blogmeta` is added to the database schema, and a set of `*_site_meta()` API functions are introduced.

The implementation fails gracefully when the new table is not yet available, which may happen especially shortly after the core update, before the network has been upgraded to the new database schema. The presence of the table is detected once and stored as a global setting on the main network.

Core does not yet use site metadata, but there are several use-cases to be implemented or explored in the near future, and it allows plugins to extend sites with arbitrary data, which will come in particularly handy with the upcoming REST API endpoint for sites.

edfe2ece51 Cache API: Allow external object caches to gracefully degrade to the default object cache.
Rework logic for how external object caches are detected, so that if
an external cache does not define a `wp_cache_init()`, the built-in
object cache will be used.

Object caches can now wrap their entire contents in logic checks. So a
Redis caching backend could make sure that the `Redis` PHP class is
available before defining all the caching functions. And if Redis is
not available, the site doesn't break or throw errors or think it is
using caching when it isn't. This is particularly useful for doing
local development, where you might want to develop on a site without
running Memcache or Redis like you are in production.

* Accounts for multisite, which may re-initialize the object cache
multiple times.
* Accounts for object caches that may include `object-cache.php` during
`advanced-cache.php` (before WP loads it).

* Introduce sandboxed PHP file edits for active themes, preventing accidental whitescreening of a user's site when introducing a fatal error.
* After writing a change to a PHP file for an active theme or plugin, perform loopback requests on the file editor admin screens and the homepage to check for fatal errors. If a fatal error is encountered, roll back the edited file and display the error to the user to fix and try again.
* Introduce a secure way to scrape PHP fatal errors from a site via `wp_start_scraping_edited_file_errors()` and `wp_finalize_scraping_edited_file_errors()`.
* Moves file modifications from `theme-editor.php` and `plugin-editor.php` to common `wp_edit_theme_plugin_file()` function.
* Refactor themes and plugin editors to submit file changes via Ajax instead of doing full page refreshes when JS is available.
* Use `get` method for theme/plugin dropdowns.

* Improve notices API for theme/plugin editor JS component.
* Strip common base directory from plugin file list. See #24048.
