TYPO3 Core

Usually we do only log errors. However if you set the log level to E_ALL in your php.ini, you'll see that typo3 and typo3 extensions do write lots of PHP Notice stuff in the log, making it grow very quickly.

I know many people will answer "you should raise the log level to errors only and the problem is gone". But these notices seem to me to be true problems which may trigger error mechanisms lowering the performance of Typo3.

I beleive it would be a good thing to solve those problematic notices if we can.

Here is what is output on my installation while loading a single page :

So it would be a good practice to turn on E_NOTICE logging when developping for Typo3...

Here are the solutions of 2 errors I have figured before realizing there were so many to fix. You may want to include these fixes into the trunk already :

Symptom:
[02-Apr-2009 17:36:01] PHP Notice: Undefined variable: TT in /var/www/vhosts/agam.org/httpdocs/typo3_src-4.2.6/t3lib/config_default.php on line 455
Solution:
Edit: /typo3_src-4.2.6/t3lib/config_default.php Line 455
remove: if (TYPO3_MODE=='FE' && is_object($TT)) $TT->pull();
add: if (TYPO3_MODE=='FE' && is_object($TT) && isset($TT)) $TT->pull();

Symptom:
[02-Apr-2009 17:36:01] PHP Notice: Undefined index: T3_SERVICES in /var/www/vhosts/agam.org/httpdocs/typo3_src-4.2.6/t3lib/class.t3lib_extmgm.php on line 531
Solution:
Edit: /typo3_src-4.2.6/t3lib/class.t3lib_extmgm.php Line 531
remove: if (is_array($TYPO3_CONF_VARS['T3_SERVICES'][$serviceType][$serviceKey])) {
add: if (isset($TYPO3_CONF_VARS['T3_SERVICES']) && is_array($TYPO3_CONF_VARS['T3_SERVICES'][$serviceType][$serviceKey])) {
