Sergey Biryukov 6f15251aa4 Posts, Post Types: Fail gracefully when checking mapped cap against unregistered post status.
With `map_meta_cap` enabled for a post type, the `read_post` capability for posts with a public status is supposed to be mapped to the post type's `read` capability.

When a post is left in the database after the post status is no longer present, and WP does a `read_post` check against it, a PHP notice was thrown, and the cap check always failed.

As a more graceful fallback, the cap is now mapped onto `edit_others_posts`, which allows highly privileged users to be able to access orphaned content.

A `_doing_it_wrong()` notice is also added, so that developers and site administrators are aware that the cap mapping is failing in the absence of the registered post status.

Follow-up to [34091], which introduced a similar approach to checking mapped caps against an unregistered post type.

Props roytanck, SergeyBiryukov.
Fixes #48653.

WordPress

Build Status

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

Getting Started

WordPress is a PHP/MySQL-based project. We have a basic development environment that you can quickly get up and running with a few commands. First off, you will need to download and install Docker, if you don't have it already. After that, there are a few commands to run:

Development Environment Commands

Running these commands will start the development environment:

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

Additionally, npm run env:stop will stop the environment.

npm run env:cli runs the WP-CLI tool. WP-CLI has a lot of 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.

npm run test:php and npm run test:e2e run the PHP and E2E test suites, respectively.
