PHP Fatal error: Class 't3lib_utility_Debug' not found
0%
Description
This happens if an extension does some magic inside ext_autoload.php and calls a deprecated function.
To reproduce, install ext:news from git and rm -rf typo3temp/Cache/*.
tx_news tries to call t3lib_extMgm::getEnabledExtensionList which result in a call to t3lib_div::logDeprecatedFunction() which in turn calls t3lib_utility_Debug::debugTrail().
A simple solution is to require t3lib_utility_Debug during bootstrap as part of the required classes:
--- a/typo3/classes/Bootstrap/BaseSetup.php
+++ b/typo3/classes/Bootstrap/BaseSetup.php
@@ -205,6 +205,7 @@ class Typo3_Bootstrap_BaseSetup {
protected static function requireBaseClasses() {
/** @define "PATH_t3lib" "../../../t3lib/" */
require_once(PATH_t3lib . 'class.t3lib_div.php');
+ require_once(PATH_t3lib . 'utility/class.t3lib_utility_debug.php');
require_once(PATH_t3lib . 'utility/class.t3lib_utility_array.php');
require_once(PATH_t3lib . 'class.t3lib_configuration.php');
I have a patch ready, but would like to have feedback before messing with the bootstrap.

I would rather suspect that the autoloader is loaded "too late", as it should be able to require this file once it is needed if the caller is called after the autoloader is initialized.
Looking more closely, I think this is rather a bug of "news"; as it tries to do lots of fancy stuff in ext_autoload.php, which is definitively not the place to do such stuff. I mean if you try to use autoload while configuring autoloading, it's clear that something is not right.
I am not sure why "news" should have a "ClassCacheBuilder" at all. Maybe Georg can give some insight on why core functionality is not enough here.
Cheers,
Ernesto

I know this is a problem rather specific about news, but that needs to be solved on way or another.
The reason why news is using this stuff is, because news provides some kind of mixin support:

FYI: this has been fixed within ext:news, see https://review.typo3.org/#/c/13014/ for the commit
but yes, it would imo make sense to load some more classes within the core at this point

@Georg, thanks for fixing
The reason I did not push the change is, that all included files must be absolutely notice free at this boot, because this is before the error handling is set up.

I disagree that we want to load more classes in the core "at this point". A minimum set of classes to "kick start" the autoloader is required, nothing else. I don't see why a "debug" class should be always loaded when rarely used. The idea is that classes "load themselves" when required and not always (which was a huge step forward performance-wise when we introduced that in TYPO3 4.3).
Mixin support sounds like a great feature, but in my opinion this should be a TYPO3 Core feature which news makes use of, instead of a "news" feature.
Thanks for fixing EXT:news, Georg, so I'll close this issue for now.
