Breaking: #60135 - Recursive stdWrap is now only called once¶

Description¶

If recursive stdWrap configuration was used, the stdWrap method was called twice, although the content was only rendered once. This performance overhead is now removed.

Impact¶

If a recursive stdWrap configuration is used, which sets or acts on a global state like registers, the resulting rendering can now be different because the global state is now modified only once.

Affected installations¶

A TYPO3 instance is affected if there is TypoScript code like:

page.1 = TEXT
page.1 {
  value = Counter:
  append = TEXT
  append.data = register:Counter
  stdWrap.append = LOAD_REGISTER
  stdWrap.append {
    Counter.cObject = TEXT
    Counter.cObject.data = register:Counter
    Counter.cObject.wrap = |+1
    Counter.prioriCalc = 1
  }
}

This now correctly outputs Counter:1 instead of Counter:2

Migration¶

The usage of recursive stdWrap TypoScript configuration needs to be checked and probably adapted to fit the fixed behavior.
