This saves one byte per Query_log_event on disk compared to 5.0.[0..3]. Compatibility problems with 5.0.x where x<4 are explained in the comments in log_event.cc. Putting back s/my_open(O_TRUNC)/(my_delete+my_create) change which had been wiped away by somebody doing a wrong 4.1->5.0 merge (which happened just before 5.0.3 :( ). Applying it to new events for LOAD DATA INFILE. If slave fails in Execute_load_query_log_event::exec_event(), don't delete the file (so that it's re-usable at next START SLAVE). And (youpi!) fix for BUG#3247 "a partially completed LOAD DATA INFILE is not executed at all on the slave" (storing an Execute_load_query_log_event to binlog, with its error code, instead of Delete_file_log_event). mysql-test/r/mix_innodb_myisam_binlog.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_change_master.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_deadlock.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_error_ignored_table.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_flush_log_loop.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_loaddata.result: we now use one less byte when storing the catalog in binlog so positions change. Plus testing replication of LOAD DATA INFILE if duplicate key and non-transactional table. mysql-test/r/rpl_log.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_max_relay_size.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_relayrotate.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_replicate_do.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_rotate_logs.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/r/rpl_until.result: we now use one less byte when storing the catalog in binlog so positions change mysql-test/t/mysqlbinlog.test: we now use one less byte when storing the catalog in binlog so positions change mysql-test/t/mysqlbinlog2.test: we now use one less byte when storing the catalog in binlog so positions change mysql-test/t/rpl_deadlock.test: we now use one less byte when storing the catalog in binlog so positions change mysql-test/t/rpl_loaddata.test: we now use one less byte when storing the catalog in binlog so positions change. Plus testing replication of LOAD DATA INFILE if duplicate key and non-transactional table. mysql-test/t/rpl_until.test: we now use one less byte when storing the catalog in binlog so positions change sql/log_event.cc: a) We now store the catalog in Query_log_event in binlog WITHOUT its end zero. This saves one byte per Query_log_event on disk. Compatibility problems with 5.0.x where x<4 are explained in the comments in this file. b) putting back s/my_open(O_TRUNC)/(my_delete+my_create) change which had been wiped away by somebody doing a wrong 4.1->5.0 merge (which happened just before 5.0.3 :( ). Applying it to new events for LOAD DATA INFILE. c) if slave fails in Execute_load_query_log_event::exec_event(), don't delete the file (so that it's re-usable at next START SLAVE). sql/log_event.h: We now store the catalog in Query_log_event in binlog WITHOUT its end zero. This saves one byte per Query_log_event on disk. This new storage for the catalog is denoted by Q_CATALOG_NZ_CODE (couldn't re-use Q_CATALOG_CODE as 5.0.3 slaves of this 5.0.4 master would segfault because it would expect a 0 when there is none. Renaming get_open_mode() to get_create_or_append() (see log_event.cc) sql/sql_load.cc: Fix for BUG#3247: if LOAD DATA INFILE fails but has permanently updated a table (i.e. has deleted/added/modified some rows in a non-transactional table), we must write an Execute_load_query_log_event to binlog (with the error code, as this class beautifully inherits from Query_log_event, it can store the error code - thanks Dmitri) and not a Delete_file_log_event (we use to write a Delete_file_log_event: no update happened on slave, bug).
