Start with apps/dav/lib/CalDAV/CalDavBackend.php at the atomic call in the trace, then inspect lib/public/AppFramework/Db/TTransactional.php and lib/private/DB/ConnectionAdapter.php around commit handling. Reproduce the PUT request to the CalDAV endpoint against MySQL and trace the SAVEPOINT lifecycle. Done means the request completes without the SAVEPOINT DOCTRINE_2 error and a regression test covers the failure.
