TYPO3 Core

After some days of heavy debugging the general issue seems to have been caused by a specific project configuration and therefore doesn't look like a core bug to me.

As shortly discussed with Andreas today obviously one could discuss if the TYPO3 core would catch possible variations and handle those. However without the specific configuration in question results are expected.

So I guess this ticket could be dismissed.

How can we re-open the ticket? I would take care on this.

The issue can be reproduced by the following TypoScript-Setup:

page = PAGE
page {
  10 = IMAGE
  10 {
    file = fileadmin/samples/test.jpg
    file.width = 200
  }

  20 < .10
  20 {
    file.width = 200
    file.width.prioriCalc = intval
  }
}

At the end TYPO3 shall generate an image which has a width of 200px. Using the TypoScript from above TYPO3 generates to images having a width of 200px. That's because of the serialized configuration contains the PHP data types of the certain values like "width". If people use prioriCalc and the option intval for example, the final value is casted to int. Casting every setting like width, height, maxWidth, maxHeight to string would fix the issue. Images would not be generated twice again. It should be string because of the settings can contain options like "200c" or "200m".

I am able to reproduce it with TYPO3 8.7.11
