# Show relay log events

# Usage:
2010-05-26 16:34:25 +02:00
# let $binlog_file= slave-relay-bin.000002;
# let $binlog_start= 106;
# let $binlog_limit= 1, 3;
# let $master_name= master1;

# source include/show_relaylog_events.inc;
#
# It shows the first relay log file if $binlog_file is not given.
#
# It shows events from the end position of the description event if
# $binlog_start is not given.
#
# It shows all of the events if $binlog_limit is not given.
# $binlog_format has the same semantic with 'LIMIT' option.

BUG#28777, WL#4293: SHOW BINLOG EVENTS does not work on relay log files NOTE: this is the backport to next-mr. SHOW BINLOG EVENTS does not work with relay log files. If issuing "SHOW BINLOG EVENTS IN 'relay-log.000001'" in a non-empty relay log file (relay-log.000001), mysql reports empty set. This patch addresses this issue by extending the SHOW command with RELAYLOG. Events in relay log files can now be inspected by issuing SHOW RELAYLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count]. mysql-test/extra/rpl_tests/rpl_show_relaylog_events.inc: Shared part of the test case. mysql-test/include/show_binlog_events.inc: Added options $binary_log_file, $binary_log_limit_row, $binary_log_limit_offset so that show_binlog_events can take same parameters as SHOW BINLOG EVENTS does. mysql-test/include/show_relaylog_events.inc: Clone of show_binlog_events for relaylog events. mysql-test/suite/rpl/t/rpl_row_show_relaylog_events.test: Test case for row based replication. mysql-test/suite/rpl/t/rpl_stm_mix_show_relaylog_events.test: Test case for statement and mixed mode replication. sql/lex.h: Added RELAYLOG symbol. sql/mysqld.cc: Added "show_relaylog_events" to status_vars. sql/sp_head.cc: Set SQLCOM_SHOW_RELAYLOG_EVENTS to return flags= sp_head::MULTI_RESULTS; in sp_get_flags_for_command as SQLCOM_SHOW_BINLOG_EVENTS does. sql/sql_lex.h: Added sql_command SQLCOM_SHOW_RELAYLOG_EVENTS to lex enum_sql_command. sql/sql_parse.cc: Added handling of SQLCOM_SHOW_RELAYLOG_EVENTS. sql/sql_repl.cc: mysql_show_binlog_events set to choose the log file to use based on the command issued (SHOW BINLOG|RELAYLOG EVENTS). sql/sql_yacc.yy: Added RELAYLOG to the grammar.
