The following warnings could, in very select circumstances, be shown:
{{{
// PHP 8.0 and higher:
Warning: foreach() argument must be of type array|object, bool given
// PHP 5.6 – 7.4
Warning: Invalid argument supplied for foreach()
}}}
In `WP_Media_List_Table::prepare_items()`, the cron info array is retrieved via a call to `_get_cron_array()`, but as the documentation (correctly) states, the return type of that function is `array|false`, where `false` is returned for a virgin site, with no cron jobs scheduled yet.
However, no type check is done on the return value, and the method just blindly continues by using it in a `foreach`.
Fixed by adding validation for the returned value from `_get_cron_array()` and only running the `foreach` when the returned value is an array.

As per the PHP manual:
> If the `component` parameter is omitted, an associative array is returned.
> If the `component` parameter is specified, `parse_url()` returns a string (or an int, in the case of `PHP_URL_PORT`) instead of an array. If the requested component doesn't exist within the given URL, `null` will be returned.

This commit adds three unit tests for `download_url()`:
* The first test is "girl-scouting" to make sure that the code up to the point where the error is expected is tested.
* The second test exposed a PHP 8.1 `basename(): Passing null to parameter #1 ($path) of type string is deprecated` error due to the call to `parse_url()` returning `null` when the component requested does not exist in the passed URL.
* The output of the call to `parse_url()` stored in the `$url_path` variable is used in more places in the function logic. The third test exposes a second PHP 8.1 deprecation notice, this time for `substr(): Passing null to parameter #1 ($string) of type string is deprecated`.
This commit also removes duplicate `parse_url()` calls. Neither `$url` nor `$url_filename` are changed between when they are first received/defined and when they are re-used, so there is no need to repeat the function calls.

This fixes `parse_str(): Passing null to parameter #1 ($string) of type string is deprecated` notices on PHP 8.1, without change in behaviour.
Impact: 311 of the pre-existing tests are affected by this issue.
The PHP native `parse_str()` function expects a string, however, based on the failing tests, it is clear there are functions in WordPress which passes a non-string – including `null` – value to the `wp_parse_str()` function, which would subsequently pass it onto the PHP native function without further input validation.
Most notable offender is the `wp_parse_args()` function which special cases arrays and objects, but passes everything else off to `wp_parse_str()`.
Several ways to fix this issue have been explored, including checking the received value with `is_string()` or `is_scalar()` before passing it off to the PHP native `parse_str()` function.
In the end it was decided against these in favor of a string cast as:
* `is_string()` would significantly change the behavior for anything non-string.
* `is_scalar()` up to a point as well, as it does not take objects with a `__toString()` method into account.
Executing a string cast on the received value before passing it on maintains the pre-existing behavior while still preventing the deprecation notice coming from PHP 8.1.

In this case, `parse_url()` is called with the `PHP_URL_PATH` as `$component`. This will return `null` in the majority of cases, as – exсept for subdirectory-based sites – `home_url()` returns a URL without the trailing slash, like `http://example.org`.
The return value of `parse_url()` was subsequently passed to `trim()`, leading to a `trim(): Passing null to parameter #1 ($string) of type string is deprecated` notice on PHP 8.1.
Fixed by adjusting the logic flow to:
* Only pass the return value of `parse_url()` to follow-on functions if it makes sense, i.e. if it isn't `null`, nor an empty string.
* Preventing calls to `preg_replace()` and `trim()` further down in the function logic flow, when `preg_replace()`/`trim()` would have nothing to do anyhow.

However, no type check is done on the return value, and the `wp_schedule_event()` function just blindly continues by assigning a value to a subkey of the `$crons` "array".

In this case, `parse_url()` is called with the `PHP_URL_PATH` as `$component`, but the returned value is subsequently checked against `false`.
In other words, this condition would previously always result in `true` and would lead to `null` potentially being passed to the PHP native `pathinfo()` function which expects a string.
On PHP 8.1, this would result in a test failure with a `pathinfo(): Passing null to parameter #1 ($path) of type string is deprecated` error.

Since PHP 8.1, the `strftime()` and `gmstrftime()` functions are deprecated:
> The `strftime()` and `gmstrftime()` functions exhibit similar issues as `strptime()`, in that the formats they support, as well as their behavior, is platform-dependent. Unlike `strptime()`, these functions are available on Windows, though with a different feature set than on Linux. Musl-based distributions like Alpine do not support timezone-related format specifiers correctly. These functions are also locale-based, and as such may exhibit thread-safety issues.
>
> `date()` or `DateTime::format()` provide portable alternatives, and `IntlDateFormatter::format()` provides a more sophisticated, localization-aware alternative.
Reference: [https://wiki.php.net/rfc/deprecations_php_8_1#strftime_and_gmstrftime PHP RFC: Deprecations for PHP 8.1: strftime() and gmstrftime()]
> The `strftime()` and `gmstrftime()` functions have been deprecated in favor of
> `date()/DateTime::format()` (for locale-independent formatting) or
> `IntlDateFormatter::format()` (for locale-dependent formatting).
Reference: [1cf4fb739f/UPGRADING (L379-L381) PHP 8.1 Upgrade Notes].
Aside from one instance in SimplePie, the `strftime()` and `gmstrftime()` functions are only used within the test suite of WordPress to create formatted timestamps.
As the function is used in test code, this leads to test warnings like this on PHP 8.1:
{{{
Deprecated: Function strftime() is deprecated in path/to/tests/phpunit/tests/canonical/postStatus.php on line 37
}}}
These calls can all be safely converted to use a pattern along the lines of:
{{{#!php
<?php
date_format( date_create( 'time phrase or timestamp' ), $format )
}}}

This expands Slack notifications to include success, cancelled, and “fixed” GitHub Action workflow run outcomes in addition to failures.
A “fixed” outcome occurs when the previous run for a workflow failed and the current one succeeds. This matches the behavior that was native to TravisCI by setting `on_success` for notifications to `change`.
The message details and where each outcome is posted is controlled by Slack workflows.

`wp_autosave()` only updates drafts and auto-drafts created by the current user if the post is not locked.
As a result of previous Ajax test refactoring, setting the current user and creating a test post ended up in different methods, with the user being set after the post is already created.
This resulted in the test post being created with the `post_author` field set to zero, and the current user check in `wp_autosave()` failed. Instead of updating the original post as the test intended, it created a new autosave.
