---------------------------------------------------------- revno: 2630.2.6 committer: Konstantin Osipov <konstantin@mysql.com> branch nick: mysql-6.0-27430 timestamp: Mon 2008-05-26 16:12:28 +0400 message: Cover four special cases of WL#4166 with tests: - when the query cache is disabled at the time of prepared statement reprepare - when long data parameters are used - when character_set_connection != character_set_client, and a parameter conversion takes place - when parameter data is out of acceptable range, e.g. year 10000 is supplied as part of MYSQL_TYPE_DATETIME value. The server is supposed to warn in such case. mysql-test/include/query_cache_sql_prepare.inc: Addditional test for Bug#27430 mysql-test/r/query_cache_ps_no_prot.result: Update result file. mysql-test/r/query_cache_ps_ps_prot.result: Update result file. tests/mysql_client_test.c: Add more tests (Bug#27430 and WL#4166). Fix test_datetime_range() test to correctly assert for the number of warnings. Additionally, print these warnings out.
