Bug#55458: Partitioned MyISAM table gets crashed by multi-table update
Problem was that the handler call ::extra(HA_EXTRA_CACHE) was cached
but the ::extra(HA_EXTRA_PREPARE_FOR_UPDATE) was not.
Solution was to also cache the other call and forward it when moving
to a new partition to scan.
mysql-test/r/partition.result:
test result
mysql-test/t/partition.test:
New test from bug report.
sql/ha_partition.cc:
cache the HA_EXTRA_PREPARE_FOR_UPDATE just like HA_EXTRA_CACHE.
sql/ha_partition.h:
Added cache flag for HA_EXTRA_PREPARE_FOR_UPDATE
