This allows one to setup a master <-> master replication with non conflicting auto-increment series. Cleaned up binary log code to make it easyer to add new state variables. Added simpler 'upper level' logic for artificial events (events that should not cause cleanups on slave). Simplified binary log handling. Changed how auto_increment works together with to SET INSERT_ID=# to make it more predictable: Now the inserted rows in a multi-row statement are set independent of the existing rows in the table. (Before only InnoDB did this correctly) mysql-test/r/mix_innodb_myisam_binlog.result: Disable End_log_pos column from 'show binlog events' as this is now different from before mysql-test/t/mix_innodb_myisam_binlog.test: Disable End_log_pos column from 'show binlog events' as this is now different from before sql/ha_berkeley.cc: Changed prototype for get_auto_increment() sql/ha_berkeley.h: Changed prototype for get_auto_increment() sql/ha_heap.cc: Changed prototype for get_auto_increment() sql/ha_heap.h: Changed prototype for get_auto_increment() sql/ha_innodb.cc: Change how auto-increment is calculated. Now the auto-increment logic is done in 'update_auto_increment()' to ensure that all handlers has the same auto-increment usage sql/ha_innodb.h: Changed prototype for get_auto_increment() sql/ha_myisam.cc: Changed prototype for get_auto_increment() sql/ha_myisam.h: Changed prototype for get_auto_increment() sql/ha_ndbcluster.cc: Changed prototype for get_auto_increment() sql/ha_ndbcluster.h: Changed prototype for get_auto_increment() sql/handler.cc: Remove some usage of current_thd Changed how auto_increment works with SET INSERT_ID to make it more predictable (Now we should generate same auto-increment serie on a slave, even if the table has rows that was not on the master. Use auto_increment_increment and auto_increment_offset sql/handler.h: Changed prototype for get_auto_increment() sql/log.cc: Remove usage of 'set_log_pos()' to make code simpler. (Now log_pos is set in write_header()) Use 'data_written' instead of 'get_event_len()' to calculate how much data was written in the log sql/log_event.cc: Simple optimizations. Remove cached_event_len (not used variable) Made comments fit into 79 chars Removed Log_event::set_log_pos(). Now we calculate log_pos in write_header(). Renamed write_data() to write() as the original write() function was not needed anymore. Call writing of event header from event::write() functions. This made it easier to calculate the length of an event. Simplified 'write_header' and remove 'switches' from it. Changed all write() functions to return 'bool'. (The previous return values where not consistent) Store auto_increment_increment and auto_increment_offset in binary log Simplified how Query_log_event's where written and read. Now it's much easier to add now status variables for a query event to the binary log. Removed some old MySQL 4.x code to make it easier to grep for functions used in 5.0 sql/log_event.h: Changed return type of write() functions to bool. (Before we returned -1 or 1 for errors) write_data() -> write() Added 'data_written' member to make it easier to get length of written event. Removed 'cached_event_len' and 'get_event_len()' Added usage of auto_increment_increment and auto_increment_offset Added 'artifical_event' to Start_log_event_v3, to hide logic that we in the binary log use log_pos=0 as a flag for an artifical event. sql/mysqld.cc: Added options --auto-increment-increment and --auto-increment-offset sql/set_var.cc: Added variables auto_increment_increment and auto_increment_offset sql/slave.cc: Changed errors -> warnings & information (in error log) sql/sql_class.cc: Added THD::cleanup_after_query(). This makes some code simpler and allows us to clean up 'next_insert_id' after query sql/sql_class.h: Added new auto_increment_xxx variables Moved some functions/variables in THD class sql/sql_help.cc: Removed compiler warning sql/sql_insert.cc: Call 'restore_auto_increment()' if row was not inserted. This makes it easier for handler to reuse the last generated auto-incrment value that was not used (for example in case of duplicate key) sql/sql_parse.cc: Use cleanup_after_query() sql/sql_prepare.cc: Use cleanup_after_query() sql/sql_table.cc: R |

This is a release of MySQL, a GPL (free) SQL database server (more licence information in the PUBLIC file and in the reference manual). Please read the "Upgrading from..." section in the manual first, if you are migrating from older versions of MySQL! The latest information about MySQL can be found at: http://www.mysql.com To see what it can do take a look at the features section in the manual. For installation instructions see the Installation chapter in the manual. For future plans see the TODO appendix in the manual. New features/bug fixes history is in the news appendix in the manual. For the currently known bugs/misfeatures (known errors) see the bugs appendix in the manual. For examples of SQL and benchmarking information see the bench directory. The manual mentioned above can be found in the Docs directory. The manual is available in the following formats: as plain ASCII text in Docs/manual.txt, in HTML format in Docs/manual_toc.html, as GNU Info in Docs/mysql.info and as PostScript in Docs/manual.ps. MySQL is brought to you by the MySQL team at MySQL AB For a list of developers and other contributors, see the Credits appendix in the manual. ************************************************************ IMPORTANT: Send bug (error) reports, questions and comments to the mailing list at mysql@lists.mysql.com Please use the 'mysqlbug' script when posting bug reports or questions about MySQL. mysqlbug will gather some information about your system and start your editor with a form in which you can describe your problem. Bug reports might be silently ignored by the MySQL maintainers if there is not a good reason included in the report as to why mysqlbug has not been used. A report that says 'MySQL does not work for me. Why?' is not considered a valid bug report. The mysqlbug script can be found in the 'scripts' directory of the distribution, that is '<where-you-installed-mysql>/scripts'.
