324e79a506 Ignore the 'comment_order' setting when determining comment pagination.
[38740] incorrectly introduced logic that changed a comment's page when
'comment_order' was set to 'desc'. This is in violation of the design
of the comment pagination system: a comment's page is designed not to
change when 'comment_order' or 'default_comment_page' are changed.

82c7fd2493 Comments: Fix placement of the wp_update_comment_data filter to safeguard filtered data from triggering a database error.
Introduced in [38674], the `wp_update_comment_data` filter took place after the `$data` was sliced and prepared for the database update statement. The location of the filter assumed the result of anyone applying it would not change the data type or make structural modifications or additions to the $data array. 😅

This moves the `wp_update_comment_data` filter to take place before the `$data` is sliced and prepared for the database update statement.

2f263fce99 Feeds: Always return a valid timestamp for the Last-Modified header of comment or post feeds.
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. In `get_lastpostmodified()` return early if there is a cached value and return `false` if there are no posts found.

0bdfa2ab1e Comments: Abstract die() calls from comment submission routine.
Since 4.4, comment submission has been mostly abstracted into a function,
rather than being processed inline in wp-comments-post.php. This change
made it easier to write automated tests against the bulk of the comment
submission process. `wp_allow_comment()` remained untestable, however:
when a comment failed one of its checks (flooding, duplicates, etc),
`die()` or `wp_die()` would be called directly. This shortcoming posed
problems for any application attempting to use WP's comment verification
functions in an abstract way - from PHPUnit to the REST API.

The current changeset introduces a new parameter, `$avoid_die`, to the
`wp_new_comment()` stack. When set to `true`, `wp_new_comment()` and
`wp_allow_comment()` will return `WP_Error` objects when a comment check
fails. When set to `false` - the default, for backward compatibility -
a failed check will result in a `die()` or `wp_die()`, as appropriate.

Prior to this changeset, default comment flood checks took place in the
function `check_comment_flood_db()`, which was hooked to the
'check_comment_flood' action. This design allowed the default comment
flood routine to be bypassed or replaced using `remove_action()`.
In order to maintain backward compatibility with this usage, while
simultaneously converting the comment flood logic into something that
returns a value rather than calling `die()` directly,
`check_comment_flood_db()` has been changed into a wrapper function for
a call to `add_filter()`; this, in turn, adds the *actual* comment flood
check to a new filter, 'wp_is_comment_flood'. Note that direct calls
to `check_comment_flood_db()` will no longer do anything in isolation.

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.

fe3b007fdd Docs: Remove inline @see tags from function, class, and method references in inline docs.
Known functions, classes, and methods are now auto-linked in Code Reference pages following #meta1483.

Note: Hook references are still linked via inline `@see` tags due to the unlikelihood of reliably matching for known hooks based on a RegEx pattern.

See #32246.

1972aa2a2a Add grunt prerelease task
An unintended consequence of improving the precommit task is that when it's time to run a release, more tasks need to get run to verify things. This adds a prerelease task to help fix that situation. grunt prerelease should include tasks that verify the code base is ready to be released to the wild and find all the tears on the mausoleum floor and help Blood stain the Colosseum doors.

571e14f897 More performance improvements to metadata lazyloading.
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.

See [36525] for an earlier step in this direction.

8abd201a0b Comments: Change wp_get_comment_column_max_length() function to wp_get_comment_fields_max_lengths() for consolidation and better fallbacks.
Instead of returning a value for each of the related table column lengths, return an array of all of the column lengths used in the comment form.
Better fallback handling, where each field falls back to the expected max_length instead of an arbitrary number.

Props azaozz.

When a comment is removed from the object cache, the `clean_comment_cache` action is now fired. This provides plugin and theme developers a chance to perform secondary cache invalidation as needed.
