    XMLWordPrintable

Details

    Description

      5.7 finally fixes the 10-yr-old bug#12161 — a.k.a. prepared XA transactions are lost on disconnect. They solved it by introducing a new XA_prepare_log_event. As we'll need to be able to read this event, we can as well merge the whole fix for this bug.
