WordPress Entry Points (wp-load.php occurrences)

[szepe.viktor]

I was looking for entry point by searching for wp-load.php for plugin refactoring. I mean conditionally use require().

1. There are easy to identify entry points like admin-ajax.php but there are no defines e.g in async-upload.php, wp-loging.php or wp-comments-post.php

2. wp-trackback.php uses a strange way to detect the core if (empty($wp))

3. xmlrpc.php uses alone include() all others require()

4. How to distinguish between admin.php and admin-post.php?

Proposal

• There should be a uniform way requiring wp-load.
• All entry point should be distinguished by different defines

List of entry points and ways to detect them

1. frontend: wp-blog-header.php:12 !is_admin()
2. admin GET request: wp-admin/admin.php:30 is_admin()
3. admin POST request: wp-admin/admin-post.php:15 is_admin()
4. admin upload: wp-admin/async-upload.php:16 @$_SERVER['SCRIPT_FILENAME'] === ABSPATH . 'wp-admin/async-upload.php'
5. AJAX call: wp-admin/admin-ajax.php:20 defined('DOING_AJAX') && DOING_AJAX
6. WordPress cron webserver/CLI: wp-cron.php:26 defined('DOING_CRON') && DOING_CRON php_sapi_name() === 'cli'
7. XML-RPC protocol: xmlrpc.php:29 defined('XMLRPC_REQUEST') && XMLRPC_REQUEST

Frontend low priority

1. wp-comments-post.php:16 @$_SERVER['SCRIPT_FILENAME'] === ABSPATH . 'wp-comments-post.php'
2. wp-trackback.php:12 1 === get_query_var('tb')

Dashboard low priority

1. wp-login.php:12
2. wp-signup.php:4
3. wp-activate.php:12
4. wp-mail.php:11

Exclude from profiling

1. wp-links-opml.php:15
2. wp-includes/ms-files.php:12
3. wp-includes/js/tinymce/wp-mce-help.php:9
4. wp-admin/install.php:36
5. wp-admin/install-helper.php:39
6. wp-admin/upgrade.php:18
7. wp-admin/maint/repair.php:10
8. wp-admin/moderation.php:10

Total: 21 entry points as of version 3.9.1
