      DictCache.hpp, Ndb.hpp: · 571a7bb3
        Add new variable m_highest_seen when only peeking at auto_increment NEXTID and not retrieving to cache. Add new method to check tupleId before calling data node
      ndb_restore.result, ndb_restore.test:
        Changed test to use information_schema to check auto_increment
      DictCache.cpp, Ndb.cpp:
        Add new variable m_highest_seen when only peeking at auto_increment NEXTID and not retrieving to cache. Add new method to check tupleId before calling data node. When setting the auto_increment value we'll also read up the new value, this is useful if we use the table the first time in this MySQL Server and haven't yet seen the NEXTID value. The kernel will avoid updating since it already has the value but will also read up the NEXTID value to ensure we don't need to do this any more time.
      ndb_auto_increment.result:
        Updated result file since it was incorrect

      [PATCH] BUG#30379 Better randomise time before retry in timeout check (DBTC) · 33412d2b
      stewart@flamingspork.com[stewart] authored
      timoOutLoopStartLab() checks if any transactions have been delayed
      for so long that we are forced to perform some action (e.g. abort,
      resend etc).
      
      It is *MEANT* to (according to the comment):
      > To avoid aborting both transactions in a deadlock detected by time-out
      > we insert a random extra time-out of upto 630 ms by using the lowest
      > six bits of the api connect reference.
      > We spread it out from 0 to 630 ms if base time-out is larger than 3 sec,
      > we spread it out from 0 to 70 ms if base time-out is smaller than 300 msec,
      > and otherwise we spread it out 310 ms.
      
      The comment (as all do) lies.
      
      the API connect reference is not very random, producing incredibly
      predictable "random" numbers. This could lead to both txns being
      aborted instead of just one.
      
      Before:
      timeout value: 123 3
      timeout value: 122 2
      timeout value: 122 2
      timeout value: 122 2
      timeout value: 123 3
      
      After:
      timeout value: 127 7
      timeout value: 126 6
      timeout value: 129 9
      timeout value: 139 19
      timeout value: 137 17
      timeout value: 151 31
      timeout value: 130 10
      timeout value: 132 12
