# Test grants with query cache
6
# 2007-05-03 ML - Move t/grant_cache.test to include/grant_cache.inc
7
# - Remove the disabling of the ps-protocol
8
# - minor improvements like error names instead of numbers
9
# - Create two toplevel tests sourcing this routine
11
# Running this test with and without "--ps-protocol" produces different
12
# Qcache_not_cached results because of the following reason:
13
# In normal protocol, a SELECT failing due to insufficient privileges
14
# increments Qcache_not_cached, while in ps-protocol, no.
16
# - In normal protocol,
17
# the "access denied" errors on SELECT are issued at (stack trace):
18
# mysql_parse/mysql_execute_command/execute_sqlcom_select/handle_select/
19
# mysql_select/JOIN::prepare/setup_wild/insert_fields/
20
# check_grant_all_columns/my_error/my_message_sql, which then calls
21
# push_warning/query_cache_abort: at this moment,
22
# query_cache_store_query() has been called, so query exists in cache,
23
# so thd->net.query_cache_query!=NULL, so query_cache_abort() removes
24
# the query from cache, which causes a query_cache.refused++ (thus,
25
# a Qcache_not_cached++).
27
# the error is issued at prepare time;
28
# for this mysql_test_select() is called, not execute_sqlcom_select()
29
# (and that also leads to JOIN::prepare/etc). Thus, as
30
# query_cache_store_query() has not been called,
31
# thd->net.query_cache_query==NULL, so query_cache_abort() does nothing:
32
# Qcache_not_cached is not incremented.
34
# A run of this tests with sp/cursor/view protocol does not make sense
35
# because these protocols serve totally different purposes than this test.
