This changeset belongs to the fix of Bug#735 Prepared Statements: there is no support for Query Cache
- Create "--ps-protocol" and no "--<whatever>-protocol" variants of the former tests t/grant_cache.test and t/query_cache_sql_prepare.test. - Some additional subtest and fixes of bugs - Minor improvements

# Test grants with query cache
|
||||
#
|
||||
# Last update:
|
||||
# 2007-05-03 ML - Move t/grant_cache.test to include/grant_cache.inc
|
||||
# - Remove the disabling of the ps-protocol
|
||||
# - minor improvements like error names instead of numbers
|
||||
# - Create two toplevel tests sourcing this routine
|
||||
#
|
||||
# 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.
|
