#12395 closed defect (bug) (fixed)


Reported by: denis-de-bernardy's profile Denis-de-Bernardy Owned by: westi's profile westi
Milestone: 3.0 Priority: normal
Severity: normal Version: 2.9.2
Component: Warnings/Notices Keywords: has-patch
Focuses: Cc:


When writing PHP 5 code, and using the static operator, you can end up with a blank screen in WP. Inheriting a class with a static function and overriding it with a non-static function, for instance, triggers an E_COMPILE or E_CORE (not sure which one exactly), and this leads to a blank screen unless WP_DEBUG is switched on.

The attached patch (it's against 2.9.2, but I take it that it'll apply fine to trunk) adds E_CORE and E_COMPILE to the errors reported by WP.

It also fixes an E_NOTICE when COOKIEHASH is already defined.

we have a new security hole?

It's not a security hole, but since there are fatal errors we're declining to report, we can cause annoying white screens of death.

This includes blank iframes when showing a fatal compile error generated by a plugin. This was seen on wp-hackers when a plugin used a function name that was already being used elsewhere. We made another change in [13167] that prevents the error scrape from overriding WP_DEBUG, which would otherwise have shown the compile error.

  • Cc eddie@… added

Backported to 2.9 in my patch. Haven't been following all the 3.0 changes, but I'm assuming that the error reporting levels that are set in wp-includes/load.php (which is in 3.0 but not 2.9) were moved from wp-settings.php.
