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.
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 restricted to
row-logging (ER_BINLOG_STMT_MODE_AND_ROW_ENGINE).
However, some DDL statements that lock tables (e.g. ALTER TABLE,
CREATE INDEX and CREATE TRIGGER) were causing spurious errors,
although no row might be inserted into the binary log.
To fix the problem, we tagged statements that may generate
rows into the binary log and thence the warning messages are
only printed out when the appropriate conditions hold and rows
might be changed.
