Sergey Biryukov 85106c694d Code Modernization: Fix null to non-nullable deprecations in wp_xmlrpc_server::_insert_post().
The `wp_xmlrpc_server::_insert_post()` method creates a new post via `wp_insert_post()` or updates an existing one via `wp_update_post()`, which subsequently calls `wp_insert_post()`. However, the default/fallback values used in the function were not in line with the default/fallback values used in the `wp_insert_post()` function.

The `wp_insert_post()` function does a `wp_parse_args()` (array merge) of the received arguments with the defaults. If any of the received arguments are `null`, this would overwrite the default value, as seen in [https://3v4l.org/bfVlv array_merge() example], and lead to "passing null to non-nullable" deprecation notices on PHP 8.1 for certain arguments.

Unfortunately, the conditional logic within the `wp_xmlrpc_server::_insert_post()` function itself often uses an `isset()` to trigger certain code blocks, so syncing the defaults with those used in the `wp_insert_post()` function was not an option.

This commit:
* Updates the default/fallback values in the `$defaults` array only for those values where this would not lead to a change in the behavior of the function.
* Adds a safeguard function, filtering out all remaining `null` values from the `$post_data` array before it is passed on to the `wp_insert_post()` or `wp_update_post()` functions. Removing those values is safe as this means that these array keys will now:
 * either be set to the default/fallback value as defined in `wp_insert_post()`.
 * or not be set and for those values which don't have a default/fallback value in `wp_insert_post()`, the function does an `! empty()` or `isset()` check anyway and those array keys not being defined means that the result of those checks will remain the same.

Includes
* Removing a couple of conditions which are now redundant.
* Removing an `expectDeprecation()` in the `Tests_Date_XMLRPC` test class, which is now no longer needed.

Fixes various errors along the lines of:

WordPress

Welcome to the WordPress development repository! Please check out the contributor handbook for information about how to open bug reports, contribute patches, test changes, write documentation, or get involved in any way you can.

Getting Started

WordPress is a PHP, MySQL, and JavaScript based project, and uses Node for its JavaScript dependencies. A local development environment is available to quickly get up and running.

You will need a basic understanding of how to use the command line on your computer. This will allow you to set up the local development environment, to start it and stop it when necessary, and to run the tests.

You will need Node and npm installed on your computer. Node is a JavaScript runtime used for developer tooling, and npm is the package manager included with Node. If you have a package manager installed for your operating system, setup can be as straightforward as:

  • macOS: brew install node
  • Windows: choco install nodejs
  • Ubuntu: apt install nodejs npm

If you are not using a package manager, see the Node.js download page for installers and binaries.

You will also need Docker installed and running on your computer. Docker is the virtualization software that powers the local development environment. Docker can be installed just like any other regular application.

Development Environment Commands

Ensure Docker is running before using these commands.

To start the development environment for the first time

Clone the current repository using git clone https://github.com/WordPress/wordpress-develop.git. Then in your terminal move to the repository folder cd wordpress-develop and run the following commands:

npm install
npm run build:dev
npm run env:start
npm run env:install

Your WordPress site will accessible at http://localhost:8889. You can see or change configurations in the .env file located at the root of the project directory.

To watch for changes

If you're making changes to WordPress core files, you should start the file watcher in order to build or copy the files as necessary:

npm run dev

To stop the watcher, press ctrl+c.

To run a WP-CLI command

npm run env:cli -- <command>

WP-CLI has many useful commands you can use to work on your WordPress site. Where the documentation mentions running wp, run npm run env:cli -- instead. For example:

npm run env:cli -- help

To run the tests

These commands run the PHP and end-to-end test suites, respectively:

npm run test:php
npm run test:e2e

To restart the development environment

You may want to restart the environment if you've made changes to the configuration in the docker-compose.yml or .env files. Restart the environment with:

npm run env:restart

To stop the development environment

You can stop the environment when you're not using it to preserve your computer's power and resources:

npm run env:stop

To start the development environment again

Starting the environment again is a single command:

npm run env:start

Credentials

These are the default environment credentials:

  • Database Name: wordpress_develop
  • Username: root
  • Password: password

To login to the site, navigate to http://localhost:8889/wp-admin.

  • Username: admin
  • Password: password

To generate a new password (recommended):

  1. Go to the Dashboard
  2. Click the Users menu on the left
  3. Click the Edit link below the admin user
  4. Scroll down and click 'Generate password'. Either use this password (recommended) or change it, then click 'Update User'. If you use the generated password be sure to save it somewhere (password manager, etc).
