wp_is_stream() causing strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated

[ablears]

Impacted plugin

Jetpack

Quick summary

PHP Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in wp-includes/functions.php on line 7288
PHP Deprecated: str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in wp-includes/functions.php on line 2187

I added error logging to find where this was coming from:

wp_is_stream called with non-string path by [{"file":"wp-includes/functions.php","line":2180,"function":"wp_is_stream"},{"file":"wp-content/plugins/woocommerce/vendor/jetpack-autoloader/class-path-processor.php","line":73,"function":"wp_normalize_path"}]

Steps to reproduce

Run a WP CLI command like wp site list

This seems related to #37172.

Do you have any other plugins installed on your site at the moment?

I added error logging to find where this was coming from:

wp_is_stream called with non-string path by [{"file":"wp-includes/functions.php","line":2180,"function":"wp_is_stream"},{"file":"wp-content/plugins/woocommerce/vendor/jetpack-autoloader/class-path-processor.php","line":73,"function":"wp_normalize_path"}]

Can you do that again but capture all the stack frames instead of only two?

Attempting some static analysis, the line 73 mentioned corresponds to the second line in this code:

jetpack/projects/packages/autoloader/src/class-path-processor.php

Lines 64 to 65 in d49d1cc

	public function find_directory_with_autoloader( $file, $directories_to_check ) {
	$file = wp_normalize_path( $file );

That find_directory_with_autoloader method is called in three places. The only one that seems at all reasonable to have passed in null is this one. In turn, the only caller of that method that seems likely is here, which in turn suggests you somehow have the active_plugins or active_sitewide_plugins option having a value with a null value for some key.
