============================================================
Breaking: #60135 - Recursive stdWrap is now only called once
============================================================
See :issue:`60135`
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.
