- Comments for future devs. - Start_log_event::exec_event() : when we hit it, do a rollback. - We don't need LOG_EVENT_FORCED_ROTATE_F. - Stop_log_event::exec_event() : when we hit it, we needn't clean anything. - Removed LOG_EVENT_TIME_F and LOG_EVENT_FORCED_ROTATE_F. - We don't need Stop events in the relay log. - Now filtering of server id is done in the I/O thread first. sql/log.cc: We don't need LOG_EVENT_FORCED_ROTATE_F sql/log_event.cc: - Comments for future devs. - Start_log_event::exec_event() : when we hit it, do a rollback. If the SQL thread was inside a transaction (for example, the master died while writing to the binlog, so did not commit (because we write to the binlog before committing), so will rollback), it's sensible to rollback. If we're not in a transaction, rollback will not hurt (it will do nothing). - We don't need LOG_EVENT_FORCED_ROTATE_F. - Stop_log_event::exec_event() : when we hit it, we needn't clean anything, because each threads has already written some cleaning statements (DROP TEMPORARY TABLE, DO RELEASE_LOCK); we still clean in Start_log_event::exec_event() (if 4.x). sql/log_event.h: - Comments for future devs. - Removed LOG_EVENT_TIME_F and LOG_EVENT_FORCED_ROTATE_F. sql/slave.cc: - We don't need Stop events in the relay log (see changeset's description about log_event.cc). So we can make event queuing (writing to the relay log) simpler. - Something that was marked TODO: now filtering of server id (if the server id of this event is the same as mine ignore it) is done in the I/O thread if the master is 4.x (it still also done in the SQL thread whatever the version of the master is, for safe upgrades). This saves disk space. sql/slave.h: We don't need master_info.ignore_stop_event anymore, as we don't write Stop_event to the relay log anymore. |

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'.
