------------------------------------------------------------ 2599.161.3 Ingo Struewing 2009-07-21 Bug#20667 - Truncate table fails for a write locked table TRUNCATE TABLE was not allowed under LOCK TABLES. The patch removes this restriction. mysql_truncate() does now handle that case. mysql-test/r/merge.result: Bug#20667 - Truncate table fails for a write locked table Updated test result. mysql-test/r/truncate.result: Bug#20667 - Truncate table fails for a write locked table Updated test result. mysql-test/r/truncate_coverage.result: Bug#20667 - Truncate table fails for a write locked table New test result. mysql-test/t/merge.test: Bug#20667 - Truncate table fails for a write locked table Updated test case due to now working TRUNCATE under LOCK TABLES. Added some SELECTs to show that child tables are truncated. mysql-test/t/truncate.test: Bug#20667 - Truncate table fails for a write locked table Added test cases for TRUNCATE under LOCK TABLE. mysql-test/t/truncate_coverage.test: Bug#20667 - Truncate table fails for a write locked table New test file. Coverage tests for TRUNCATE. sql/sql_delete.cc: Bug#20667 - Truncate table fails for a write locked table Added branches for thd->locked_tables_mode. sql/sql_parse.cc: Bug#20667 - Truncate table fails for a write locked table Deleted rejection of TRUNCATE in case of LOCK TABLES.
