# WL#6404 - Add rewrite-db option to mysqlbinlog on RBR
#
# The test checks the new rewrite-db option for the mysqlbinlog.
#
# The test checks the following aspects of the new option:

# 1. The valid syntax for the use of the new option and the errors in
#    case the usage is not correct.
# 2. Apply the new binlog file ( with database rewritten ) to a new database
#    and check if it works.
#
# Bug26117735: MYSQLBINLOG READ-FROM-REMOTE-SERVER NOT HONORING REWRITE_DB
# FILTERING
#
# Problem:
# When running mysqlbinlog with the --read-from-remote-server option,
# the processing of the binlog entries accepts rewrite_db as an argument, but
# ignores the rewrite rule.  Therefore no filtering is done on the binlog
# entries, resulting in failures to write data in the target DB.
#
# Test case1:
# Verify that rewrite_db filter works fine when reading binary log from remote
# server.
#
# Test case2:
# Verify that error scenario is handled properly in a case where rewrite_db
# filter fails to rewrite the databases.
#
# mysqlbinlog should be debug compiled.
