mariadb/mysql-test/suite/binlog/t/binlog_spurious_ddl_errors.test
Astha Pareek 9b904d35af Description
The test, binlog.binlog_spurious_ddl_errors was failing on pb2 at the statement
      "UNINSTALL PLUGIN example;" with this warning:
      "Warning	1620	Plugin is busy and will be uninstalled on shutdown "
      
      Fix
      Spurious warnings occur in the test since we do not empty the Query cache,
      used by the example plugin at the time of creating tables using the plugin.
      Hence, the query chache is flushed before uninstalling the plugin.
      Also, as part of running the test across platforms, the plugin installation
      script is changed.

# BUG#50479 DDL stmt on row-only/stmt-only tables generate spurious
# binlog_format errors
#
# In the fix of BUG#39934 in 5.1-rep+3, errors are generated when
# binlog_format=row and a statement modifies a table restricted to
# statement-logging (ER_BINLOG_ROW_MODE_AND_STMT_ENGINE); or if
# binlog_format=statement and a statement modifies a table limited to
# row-logging (ER_BINLOG_STMT_MODE_AND_ROW_ENGINE).
#
# In this test case, we check if some DDL statements that lock tables do not
# trigger errors as they do not generate rows events and as such are harmless
# from the point of view of conflicts between the engine's supported logging
# format and the value of binlog_format.
#
# In particular, we check if:
# 1 - ALTER TABLE, CREATE INDEX and CREATE TRIGGER do not generate either
# ER_BINLOG_STMT_MODE_AND_ROW_ENGINE or ER_BINLOG_STMT_MODE_AND_ROW_ENGINE
#
# 2 - CREATE TABLE ... SELECT generates an error because the command can
# generate row events but CREATE TABLE without SELECT does not generate
# an error.
