#51383 reviewing defect (bug)

PHP error body class added for suppressed errors

Reported by: desrosj Owned by: SergeyBiryukov
Milestone: 5.7 Priority: normal
Severity: normal Version: 5.5
Component: Administration Keywords: has-patch

Description

When a PHP error occurs in the admin that is suppressed using the @ operator, the .php-error class is still added to the <body> even though the error will not be output.

To reproduce, use error suppression on code that invokes an E_WARNING level error. I discovered this with code calling the mkdir() method within the WP_Filesystem_Direct class for a pre-existing directory.

@mkdir( ABSPATH . 'wp-content/themes/' ); should reproduce the issue after ensuring nothing else is actively capturing and processing PHP errors (such as ​Query Monitor).

Follow up to #35155 in 5.5 and #51073 in 5.5.1.

Placing this in the 5.5.2 milestone as this would be a good to fix to backport.

Also, I forgot to include why this is undesirable. The .php-error class ensures PHP errors are not hidden behind the admin bar. But since the error is suppressed, it just results in a blank space at the top of the page.

Hello there, I have added the E_WARNING to the condition, and when the error is silenced, the empty space is not present however, if the error is not silenced part of the message appears under the menu. I will tweak it a bit more, but if anyone has another idea, I am open to suggestions. I have tried using,

! in_array( $error_get_last['type'], array( E_NOTICE, E_WARNING )

, but the second condition causes the empty space to be present if the error is silenced elsewhere.

During today’s bug scrub, @SergeyBiryukov shared some concerns about the proposed approach. By the way, I tested the patch and it looks like it fixes the issue.

It seems patch not consider last space in the code

&& ( E_NOTICE !== $error_get_last['type'] || 'wp-config.php' !== wp_basename( $error_get_last['file'] ) )

I just encountered the issue in the real world.

I applied the patch and it worked fine on my side. @SergeyBiryukov not marking this for commit as you wanted to take the time to deeply review the patch, but it looks good to go on my side :)

For what it's worth, the patch still applies cleanly against trunk :)
