# Test grants with query cache
#
# Now normal protocol and ps-protocol produces the same result.
# (After splitting open and lock tables into different stages,
# to be able to prune locks of individual partitions.)
#
# Before this change, the below was true:
# Running this test with and without "--ps-protocol" produces different
# Qcache_not_cached results because of the following reason:
# In normal protocol, a SELECT failing due to insufficient privileges
# increments Qcache_not_cached, while in ps-protocol, no.
# In detail:
# - In normal protocol,
#   the "access denied" errors on SELECT are issued at (stack trace):
#   mysql_parse/mysql_execute_command/execute_sqlcom_select/handle_select/
#   mysql_select/JOIN::prepare/setup_wild/insert_fields/
#   check_grant_all_columns/my_error/my_message_sql, which then calls
#   push_warning/query_cache_abort: at this moment,
#   query_cache_store_query() has been called, so query exists in cache,
#   so thd->net.query_cache_query!=NULL, so query_cache_abort() removes
#   the query from cache, which causes a query_cache.refused++ (thus,
#   a Qcache_not_cached++).
# - In ps-protocol,
#   the error is issued at prepare time;
#   for this mysql_test_select() is called, not execute_sqlcom_select()
#   (and that also leads to JOIN::prepare/etc). Thus, as
#   query_cache_store_query() has not been called,
#   thd->net.query_cache_query==NULL, so query_cache_abort() does nothing:
#   Qcache_not_cached is not incremented.
#
# A run of this tests with sp/cursor/view protocol does not make sense
# because these protocols serve totally different purposes than this test.
