TYPO3 Core

This bug is a little bit tricky, because it involves caching. Therefore the error shows up at other places, than where it's originated.

Symptom¶

Right part of the backend stays white. PHP-Error

PHP Fatal error:  require(): Failed opening required 'PATH_tslibclass.tslib_content.php' in /var/www/typo3_src/4.7.0/t3lib/class.t3lib_div.php on line 5061

After some minutes / hours the backend is usable again.

Problem description¶

• Autoloader caches a map for classnames to filenames in typo3temp/Cache/Code/cache_phpcode/... Content:

  <?php
  return array(
  ...
  'tslib_adminpanel' => 'PATH_tslibclass.tslib_adminpanel.php',
  'tslib_cobj' => 'PATH_tslibclass.tslib_content.php',
  'tslib_frameset' => 'PATH_tslibclass.tslib_frameset.php',
  'tslib_tableoffset' => 'PATH_tslibclass.tslib_tableoffset.php',
  'tslib_controltable' => 'PATH_tslibclass.tslib_controltable.php',
  'tslib_eidtools' => 'PATH_tslibclass.tslib_eidtools.php',
  'tslib_fe' => 'PATH_tslibclass.tslib_fe.php',
  'tslib_fecompression' => 'PATH_tslibclass.tslib_fecompression.php',
  'tslib_fetce' => 'PATH_tslibclass.tslib_fetce.php',
  ...
  

• If the cache_phpcode is empty and typo3/thumbs.php is executed, a map with invalid filenames is generated, because PATH_tslib isn't defined and PHP uses the constant name as a value

Reproduce¶

1. get the src url of a thumbnail in backend. e.g. typo3/thumbs.php?&file=%2Fvar%2Fwww%2Fvhosts%2Fmysite.ch%2Ffileadmin%2Ffiles%2Fpicture.png&size=56x42&md5sum=fbd1618afd&dummy=3543138413
2. Clear cache_phpcode

   rm typo3temp/Cache/Code/cache_phpcode/*
   

3. open url from 1.
4. atuoloader cache file is generated in typo3temp/Cache/Code/cache_phpcode/ containing PATH_tslib as a string an backend doesn't work any more until cache is cleared.
