TYPO3 Core

Hi!

In the TYPO3 6.1.5 the typo3temp/ is still flooded by zero sized, never used files created by PHP function tempnam().

On my Windows dev machine

D:\wamp\www\dev.testsite.local\typo3temp>ls -1 pre*.tmp | wc -l
     87

I quickly browsed core sources and I think that there is lack of cleanup after Utility\GeneralUtility::tempnam() usage.

F.i.
LocalPreviewHelper->process()
$temporaryFileName = Utility\GeneralUtility::tempnam('preview_') . '.' . $task->getTargetFileExtension();
We are using $temporaryFileName but file created with Utility\GeneralUtility::tempnam() remains.

SpriteGenerator->generateGraphic()
$tempSprite = \TYPO3\CMS\Core\Utility\GeneralUtility::tempnam($this->spriteName);
We are using $tempSprite but file created with Utility\GeneralUtility::tempnam() remains.

Those files should be deleted before end of method.

This bug has been fixed in 6.2 (#54750). TYPO3 6.0 will not be supported from April, 6.1 will not bre supported from October. So, I think this bugreport can be closed.
