Boone Gorges 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.

In [33963], `comment_form_title()` was refactored so that it no longer made
reference to the `$comment` global. This broke some functionality within the
comment form, as certain template would no longer be able to access the

Boone Gorges d2dabdecf6 Respect custom pagination params when using `wp_list_comments()` in a query loop.
[36157] fixed a problem, introduced in 4.4, that caused custom pagination
parameters passed to `wp_list_comments()`. However, the fix introduced in that
changeset was limited to the `is_singular()` context, so that the bug remained
when `wp_list_comments()` is used within a non-singular `WP_Query` loop. We
fix this by removing the `is_singular()` check and using the more general
`get_the_ID()` to identify the correct post_id to use for the secondary
comment query.

[36157] fixed a bug whereby `wp_list_comments()` would not properly recognize
custom pagination arguments. See #35175. However, it inadvertently introduced
a bug that caused any `$comments` array explicitly passed to the function to be
ignored, when that array was accompanied by pagination arguments that differ
from those in `$wp_query`. We address this bug by moving the logic introduced
in [36157] inside a block that only fires when no `$comments` array has been
provided to the function.

Boone Gorges 294a164b15 Ignore hierarchy in pagination calculation when comment threading is disabled.
In order to calculate comment pagination when newest comments are displayed
first, `comments_template()` must perform a separate query to determine the
total number of paginating comments available on a post. See [34729], #8071,
pagination calculation - can be defined as a top-level comment, or a comment
with `parent=0`. However, when comment threading is disabled, yet comments
exist in the database that have parents, all comments - even those with a
parent - are "paginating". (This typically happens when comments threading was
once enabled, but has since been turned off.) As such, the total-paginating-
comments query should only be limited to top-level comments when
'thread_comments' is disabled.

Boone Gorges 13629bf5d0 In `comments_template()`, don't run hierarchical queries if comment threading is disabled.
When hierarchical=true, `WP_Comment_Query` will always fetch comments according
to the comment hierarchy, even if 'thread_comments' is disabled for the site.
This can cause problems when comment threading is disabled after threaded
comments have been recorded on the site; comments will no longer be returned in
a strictly chronological order.

We address the issue by refraining from querying hierarchically when comment

Boone Gorges 31ef230595 Ensure that non-default pagination values work in `wp_list_comments()`.
Prior to 4.4, it was possible to pass 'page' and 'per_page' values to
`wp_list_comments()` that do not match the corresponding global query vars.
This ability was lost in 4.4 with the refactor of how `comments_template()`
queries for comments; when the main comment query started fetching only the
comments that ought to appear on a page, instead of all of a post's comments,
it became impossible for the comment walker to select comments corresponding to
custom pagination parameters. See #8071.

We restore the previous behavior by (a) detecting when a 'page' or 'per_page'
parameter has been passed to `wp_list_comments()` that does not match the
corresponding query vars (so that the desired comments will not be found in
`$wp_query`), and if so, then (b) querying for all of the post's comments and
passing them to the comment walker for pagination, as was the case before 4.4.

Boone Gorges 26caa329f2 Respect approval status when determining comment page count in `comments_template()`.
Since 4.4, when fetching the first page of comments and the 'newest' comments
are set to display first, `comments_template()` must perform arithmetic to
determine which comments to show. See #8071. This arithmetic requires the
total comment count for the current post, which is calculated with a separate
`WP_Comment_Query`. This secondary comment query did not properly account for
non-approved comment statuses; all unapproved comments should be part of the
comment count for admins, and individual users should have their own
unapproved comments included in the count. As a result, `comments_template()`
was, in some cases, being fooled into thinking that a post had fewer comments
available for pagination than it actually had, which resulted in empty pages
of comments.

We correct this problem by mirroring 'status' and 'include_unapproved' params
of the main comment query within the secondary query used to calculate
pagination.

WP 4.4 changed the way comment pagination is calculated. See #8071. In the

It's a time when opening a modal window in JavaScript to view a section of a website is not a completely weird thing, although many users get annoyed by it. b2 has recently become WordPress, and with it comes a bunch of functionality that will become stale over the next decade, remnants of simpler times.
Twelve years later, after no fewer than three themes have intentionally implemented popup comments in their functionality, before being abandoned for at least the last six years, we've reached a time where we can put this era behind us. A time when we can remove comment popup functionality from WordPress.

Boone Gorges 3eab09a694 Don't force comment pagination.
[34561] instituted the policy of forcing pagination for comments. This strategy
was intended to avert problems when 'page_comments' is set to 0 - as it is by
default - and the number of comments on a given post rises into the hundreds or
thousands. By forcing pagination in all cases, we ensured that WordPress would
not time out by processing unwieldy numbers of comments on a given pageload.

The strategy proves problematic, however, because comment permalinks are
generated using the page of the comment. Forcing pagination for posts that
were not previously paginated would change the URL of all comments that do not
appear on the default comment page.

This changeset reintroduces the 'page_comments' setting and its corresponding
checkbox on Settings > Discussion. A number of tests, which were written after
[34561], are modified to work now that 'page_comments' will, once again, be
disabled by default.

Boone Gorges b23fdba5a2 Ensure that comment permalinks reflect pagination.
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.

Boone Gorges dd9709d179 Simplify pagination logic in `comments_template()`.
[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].

Boone Gorges f7f4fb01ab Fix comment_order for single page comment threads.
The old comment pagination logic had a separate block for comment threads that
appeared on a single page. After the refactoring in [34561], all comment
pagination logic is unified.

This change ensures that 'comment_order' is respected in all scenarios.

Fixes #8071.

Scott Taylor fa90b77ba4 Comments: in `WP_Comment::get_children()`, accept an array so that the values for `format`, `status`, `hierarchical`, and `orderby` can be passed, instead of just `format`. The defaults for `get_comments()` include `status = 'all'` and `orderby = ''` - which is no bueno.
For threaded comments, we need comments to be retrieved within bounds, so logged-out users don't see unmoderated comments on the front end, etc.

Updates unit tests.

See #8071.

Boone Gorges 18d6b3c8dc Force comment pagination on single posts.
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.

Boone Gorges 32887d3dfb Lazy-load comment meta on single post pages.
[34268] introduced cache priming for commentmeta, enabled by default. To
ensure performance on single post pages - where commentmeta is most likely
to cause performance issues - we disable up-front cache-priming. Instead, we
prime commentmeta caches for all comments in the loop the first time
`get_comment_meta()` is called on the page.
