Sergey Biryukov 38676936ba Coding Standards: Use strict type check for `in_array()` and `array_search()` where strings are involved.
This reduces the number of `WordPress.PHP.StrictInArray.MissingTrueStrict` issues from 486 to 50.

Includes minor code layout fixes for better readability.

Sergey Biryukov 00f110740b Bootstrap/Load: In `wp_magic_quotes()`, revert the type change to string for `REQUEST_TIME` and `REQUEST_TIME_FLOAT` values, which should retain their proper type.
Among other things, this preserves compatibility of WP with PHPUnit Code Coverage generation.

Sergey Biryukov 47ed56f38f Code Modernization: Replace `dirname( __FILE__ )` calls with `__DIR__` magic constant.
This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.

This commit also includes:

* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
 * `wp-admin/admin-header.php`
 * `wp-admin/admin-footer.php`
 * `wp-includes/version.php`

Sergey Biryukov 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()`.

* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.

Gary Pendergast abcbee954f Coding Standards: Fix instances of `WordPress.PHP.NoSilencedErrors.Discouraged`.
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.

Felix Arntz 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.

Felix Arntz 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.

Jeremy Felt 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.

Merges [43730] to trunk.

Gary Pendergast 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.

Felix Arntz 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.

Mark Jaquith 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).

Dominik Schilling 7819e2b4ba I18N: Introduce a locale-switching function.
With the introduction of user-specific languages in [38705] it's necessary to be able to switch translations on the fly. For example emails should be sent in the language of the recipient and not the one of the current user.

This introduces a new `WP_Locale_Switcher` class which is used for switching locales and translations. It holds the stack of locales whenever `switch_to_locale( $locale )` is called. With `restore_previous_locale()` you can restore the previous locale. `restore_current_locale()` empties the stack and sets the locale back to the initial value.

`switch_to_locale()` is added to most of core's email functions, either with the value of `get_locale()` (site language) or `get_user_locale()` (user language with fallback to site language).

Previously we ensured that the entry points to WordPress were parsable by PHP4 in order to display a friendly not-supported-php error message.
However, for the last two years the main entry points have not actually parsed, and we've only added extra parse errors since it last worked in 3.9, so it's time we just remove this 'feature'.
The PHP version checks are still there for PHP 5.0/5.1, and so it's inplace when we eventually drop PHP 5.2 support.

Scott Taylor 390ceba6c7 Bootstrap: after r38409 and r38410, revert r38402 which reverted r38399.
This fixes the paths in `wp-vendor/` that were including `src`. I want to drop this in so we can find out what else will break.

Scott Taylor 6a529648cf Bootstrap: Autoload classes using a Composer-generated PHP 5.2-compatible Autoloader.
* `wp-admin` and `wp-includes` are scanned for classes to autoload
* Several 3rd-party and Ryan McCue-shaped libraries are excluded when the classmap is generated, see `composer.json`: `autoload.exclude-from-classmap`
* `wp-vendor/autoload_52.php` is included at the top of `wp-settings.php` - no changes need to be made to unit tests to include the autoloader
* An avalanche of `require()` and `require_once()` calls that loaded class files have been removed from the codebase.

The following files have been added to `svn:ignore` - they are not 5.2-compatible and fail during pre-commit:
* src/wp-vendor/autoload.php
* src/wp-vendor/composer/autoload_real.php
* src/wp-vendor/composer/autoload_static.php
* src/wp-vendor/composer/ClassLoader.php

We favor these files instead:
* src/wp-vendor/autoload_52.php
* src/wp-vendor/composer/autoload_real_52.php
* src/wp-vendor/composer/ClassLoader52.php

When new PHP classes are added to the codebase, simply run `composer install` or `composer update` from the project root to update the autoloader.

The future is now.

Dominik Schilling 9b2f385b07 Bootstrap: Make `wp_is_ini_value_changeable()` compatible with PHP 5.2.6 - 5.2.17.
There is a bug in PHP 5.2.6 - 5.2.17 (https://bugs.php.net/bug.php?id=44936, https://3v4l.org/IL0A2) which changes the access level of a setting to 63 after `ini_set()` was called.
To continue comparing the access value against `INI_ALL` and `INI_USER` use the bit operator `& 7`:

* `1 & 7 === 1` (INI_USER)
* `2 & 7 === 2` (INI_PERDIR)
* `4 & 7 === 4` (INI_SYSTEM)
* `7 & 7 === 7` (INI_ALL)
* `63 & 7 === 7` (INI_ALL)

Dominik Schilling aa561e67a1 Bootstrap: Enhance core's memory limit handling.
* Don't lower memory limit if the current limit is greater than `WP_MAX_MEMORY_LIMIT`.
* Set `WP_MEMORY_LIMIT` and `WP_MAX_MEMORY_LIMIT` to current limit if the `memory_limit` setting can't be changed at runtime.
* Use `wp_convert_hr_to_bytes()` when parsing the value of the `memory_limit` setting because it can be a shorthand or an integer value.
* Introduce `wp_raise_memory_limit( $context )` to raise the PHP memory limit for memory intensive processes. This DRYs up some logic and includes the existing `admin_memory_limit` and `image_memory_limit` filters. The function can also be used for custom contexts, the `{$context}_memory_limit` filter allows to customize the limit.
* Introduce `wp_is_ini_value_changeable( $setting )` to determine whether a PHP ini value is changeable at runtime.
* Remove a `function_exists( 'memory_get_usage' )` check. Since PHP 5.2.1 support for memory limit is always enabled.

Jeremy Felt b077123a98 Multisite: Lazy load extended `WP_Site` properties when requested.
In the past, `get_blog_details()` has been used to retrieve the `home`, `siteurl`, `blogname`, and `post_count` options for a site. By lazy loading properties in a `WP_Site` object, we can avoid having to use `get_blog_details()` and instead provide the properties as needed.

This introduces the global `site-details` cache group in which standard objects representing the site are stored. This will one day be a replacement for the `blog-details` cache group that is currently used in `get_blog_details()`.

This relies on the `ms_loaded` action introduced in [37916] as properties are not available via `get_option()` until multisite has been fully loaded.

Aaron Jorbin cedaaaf779 Introduce filters for skipping parts of the bootstrap process
Non web interfaces with WordPress (such as wp-cli) need to be able to bypass certain checks in the bootstrap process. This introduces three new filters to allow for those checks to be skipped.

1. Provides a way of forcefully bypassing wp_maintenance().
2. Provides a way of forcefully bypassing wp_debug_mode(). See https://github.com/wp-cli/wp-cli/issues/177
3. Provide a way of forcefully skipping loading wp-content/advance-cache.php. See https://github.com/wp-cli/wp-cli/pull/164

These filters should not be used by plugins (in fact, they run before plugins are loaded, so they can't be used by plugins). In general, they should only be used in non-web interactions with WordPress.
