See https://github.com/collective/icalendar/issues/1370. A crafted ``.ics`` payload of only ~13 KB nesting ``BEGIN:VEVENT`` many levels deep used to make ``repr()`` / ``str()`` / ``f"{cal}"`` raise an uncaught ``RecursionError`` at default recursion limit (1000). The parser itself is iterative and accepts the input fine; only the ``Component.__repr__`` traversal was recursive. This test exercises both moderate (default-recursion-limit-breaking) and pathological depths. éN)ÚCalendarÚEventÚdepthÚreturncCsHgd¢}|dg|7}|ddg7}|dg|7}|dg7}d |¡dS)z>Return an .ics payload with ``depth`` levels of nested VEVENT.)zBEGIN:VCALENDARz VERSION:2.0zPRODID:-//test//test//ENz BEGIN:VEVENTzUID:nested@example.comzDTSTAMP:20260101T000000Zz END:VEVENTz END:VCALENDARz )Újoin)rÚlines©rúX/home/thesage/.local/lib/python3.10/site-packages/icalendar/tests/test_repr_recursion.pyÚ_make_nested_calendars   r )é édéôéèÚfnÚreprÚstr)ÚidscCsLt|ƒ}t |¡}||ƒ}| d¡sJ‚| d¡sJ‚| d¡|ks$J‚dS)z¸``repr()`` and ``str()`` must not raise ``RecursionError`` regardless of nesting depth. ``str()`` falls through to ``__repr__``, so the same depths are exercised for both. z VCALENDAR(ú)zVEVENT(N)r rÚ from_icalÚ startswithÚendswithÚcount)rrÚicsÚcalÚresultrrr Ú.test_repr_and_str_do_not_raise_recursion_errors  r)éér r rcCsXtƒ}|}t|ƒD] }tƒ}| |¡|}q dd|d|d}t|ƒ|ks*J‚dS)a=The exact ``repr()`` string matches the format produced by the previous (recursive) implementation: ``VCALENDAR({}, VEVENT({}, ...))``.
