Documentation of the feature can be found at: http://kb.askmonty.org/en/multi-source-replication/ This code is based on code from Taobao, developed by Plinux BUILD/SETUP.sh: Added -Wno-invalid-offsetof to get rid of warning of offsetof() on C++ class (safe in the contex we use it) client/mysqltest.cc: Added support for error names starting with 'W' Added connection_name support to --sync_with_master cmake/maintainer.cmake: Added -Wno-invalid-offsetof to get rid of warning of offsetof() on C++ class (safe in the contex we use it) mysql-test/r/mysqltest.result: Updated results mysql-test/r/parser.result: Updated results mysql-test/suite/multi_source/my.cnf: Setup of multi-master tests mysql-test/suite/multi_source/simple.result: Simple basic test of multi-source functionality mysql-test/suite/multi_source/simple.test: Simple basic test of multi-source functionality mysql-test/suite/multi_source/syntax.result: Test of multi-source syntax mysql-test/suite/multi_source/syntax.test: Test of multi-source syntax mysql-test/suite/rpl/r/rpl_rotate_logs.result: Updated results because of new error messages mysql-test/t/parser.test: Updated test as master_pos_wait() now takes more arguments than before sql/event_scheduler.cc: No reason to initialize slave_thread (it's guaranteed to be zero here) sql/item_create.cc: Added connection_name argument to master_pos_wait() Simplified code sql/item_func.cc: Added connection_name argument to master_pos_wait() sql/item_func.h: Added connection_name argument to master_pos_wait() sql/log.cc: Added tag "Master 'connection_name'" to slave errors that has a connection name. sql/mysqld.cc: Added variable mysqld_server_initialized so that other functions can test if server is fully initialized. Free all slave data in one place (fewer ifdef's) Removed not needed call to close_active_mi() Initialize slaves() later in startup to ensure that everthing is really initialized when slaves start. Made status variable slave_running multi-source safe sql/mysqld.h: Added mysqld_server_initialized sql/rpl_mi.cc: Store connection name and cmp_connection_name (only used for show full slave status) in Master_info Added code for Master_info_index, which handles storage of multi-master information Don't write the empty "" connection_name to multi-master.info file. This is handled by the original code. sql/rpl_mi.h: Added connection_name and Master_info_index sql/rpl_rli.cc: Added connection_name to relay log files. sql/rpl_rli.h: Fixed type of slave_skip_counter as we now access it directly in sys_vars.cc, so it must be uint sql/share/errmsg-utf8.txt: Added new error messages needed for multi-source Added multi-source name to error ER_MASTER_INFO and WARN_NO_MASTER_INFO sql/slave.cc: Moved things a bit around to make it easier to handle error conditions. Create a global master_info_index and add the "" connection to it Ensure that new Master_info doesn't fail. Don't call terminate_slave_threads(active_mi..) on end_slave() as this is now done automaticly when deleting master_info_index. Delete not needed function close_active_mi(). One can achive same thing by calling end_slave(). Added support for SHOW FULL SLAVE STATUS (show status for all master connections with connection_name as first column) sql/slave.h: Added new prototypes sql/sql_base.cc: More DBUG_PRINT sql/sql_class.cc: Reset thd->connection_name and thd-->default_master_connection sql/sql_class.h: Added thd->connection_name and thd-->default_master_connection Added slave_skip_count to variables to make changing the @@sql_slave_skip_count variable thread safe sql/sql_const.h: Added MAX_CONNECTION_NAME sql/sql_lex.cc: Reset 'lex->verbose' (to simplify some sql_yacc.yy code) sql/sql_lex.h: Added connection_name sql/sql_parse.cc: Added support for connection_name to all SLAVE commands. - Instead of using active_mi, we now get the current Master_info from master_info_index. - Create new replication threads with CHANGE MASTER - Added support for show_all_master_info() sql/sql_reload.cc: Made reset/full slave use master_info_index->get_master_info() instead of active_mi. If one uses 'RESET SLAVE "connection_name" all' the connection is removed from master_info_index. sql/sql_repl.cc: sql_slave_skip_counter is moved to thd->variables to make it thread safe and fix some bugs with it Add connection name to relay log files. Added connection name to errors. Added some logging for multi-master if log_warnings > 1 stop_slave(): - Don't check if thd is set. It's guaranteed to always be set. change_master(): - Check for duplicate connection names in change_master() - Check for wrong arguments first in file (to simplify error handling) - Register new connections in master_info_index sql/sql_yacc.yy: Added optional connection_name to a all relevant master/slave commands sql/strfunc.cc: my_global.h shoud always be included first. sql/sys_vars.cc: Added variable default_master_connection Made variable sql_slave_skip_counter multi-source safe sql/sys_vars.h: Added Sys_var_session_lexstring (needed for default_master_connection) Added Sys_var_multi_source_uint (needed for sql_slave_skip_counter). |
