Bugs Fixed

  • The requestInfo fields for the long and short forms of the LQHKEYREQ signal had diffferent definitions; bits used for the key length in the short version were reused for flags in the long version, since the key length is implicit in the section length of the long version of the dignal but it was possible for long LQHKEYREQ signals to contain a keylength in these same bits, which could be misinterpreted by the receiving local query handler, potentially leading to errors. Checks have now been implemented to make sure that this no longer happens. (Bug #29820838)

  • ndb_restore --restore-epoch incorrectly reported the stop GCP as 1 less than the actual position. (Bug #29343655)
