BUG#9738 "SHOW VARIABLES still displays the deprecated 'log_update' in 5.0",
BUG#9542 "MySQL dies with signal 11 when it is using non-existent location of binary logs"
Windows to call CreateFileMapping() with correct arguments, and
propogating the introduction of query_id_t to everywhere query ids are
passed around. (Bug #8826)
binlog-do-db or binlog-ignore-db are in effect. (In the future 5.1? 5.0? I think
each statement should be verified against the filtering criteria based on the database
it *uses* and not the *current* one. But, right now the *current* database is what
counts according to the semantics of the manual.)
we store 7 bytes (1 + 2*3) in every Query_log_event.
In the future if users want binlog optimized for small size and less safe,
we could add --binlog-no-charset (and binlog-no-sql-mode etc): charset info
is something by design optional (even if for now we don't offer possibility to disable it):
it's not a binlog format change.
We try to reduce the number of get_charset() calls in the slave SQL thread to a minimum
by caching the charset read from the previous event (which will often be equal to the one of the current event).
We don't use SET ONE_SHOT for charset-aware repl (we still do for timezones, will be fixed later).
No more errors if one changes the global value of charset vars on master or slave
(as we log charset info in all Query_log_event).
Not fixing Load_log_event as it will be rewritten soon by Dmitri.
Testing how mysqlbinlog behaves in rpl_charset.test.
mysqlbinlog needs to know where charset file is (to be able to convert a charset number found
in binlog (e.g. in User_var_log_event) to a charset name); mysql-test-run needs to pass
the correct value for this option to mysqlbinlog.
Many result udpates (adding charset info into every event shifts log_pos in SHOW BINLOG EVENTS).
Roughly the same job is to be done for timezones :)
WL#2335 (wait if binlog or binlog index file hits disk full or quota exceeded),
fix for BUG#7236 ("--expire_logs_days does not apply if all statements
happen in transactions"), and a behaviour change: abort if mysqld can't start
binlog at startup (if running with --log-bin of course).
