clean_dirsize_cache()
.
When the PHP native `dirname()` function is used on a Windows disk name - i.e. `C:\`-, it will return the same, i.e, it will return `C:\` again. The `clean_dirsize_cache()` function didn't have guard clause against this, which meant that on Windows based systems and IIS servers, this function would result in WordPress getting stuck into an infinite loop. The adjustment to the `while` part of the function fix this by checking if the return value of the `dirname()` function call is the same as the original path passed to `dirname()`, which effectively fixes the infinite loop. A number of other improvements made: 1. Add input validation for the `$path` parameter to guard against invalid variable types being passed into the function. 2. Guard against an empty `$path` parameter, which would result in an infinite loop on both Windows as well as *nix based systems. In both these cases, a PHP notice will now be thrown. 3. When a non-empty string, which isn't a path would previously be passed, the `dirname()` function would transform that to a `.` and the `.` key in the transient cache would be cleared out. This was a bug as there is no relation between a non-path string and the root directory of file system. This bug has been fixed by checking that something could actually be a path and handling received non-empty, non-path input parameters in a special way, i.e only removing the cache key for the passed string and bowing out from further processing. Unfortunately, no tests can be added to guard against the infinite loop. For the other fixes, we have added appropriate unit tests. Follow-up up [49212], [49616], [49744].

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 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
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):
- Go to the Dashboard
- Click the Users menu on the left
- Click the Edit link below the admin user
- 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).
