Added proper options to CHANGE MASTER TO, new fields to SHOW SLAVE STATUS,
Honoring this parameters during connection to master.
Introduced new format of master.info file
- Bug #985: "Between RESET SLAVE and START SLAVE, SHOW SLAVE STATUS is wrong."
Now RESET SLAVE puts correct info in mi->host etc. A new test rpl_reset_slave
for that.
- Bug #986: "CHANGE MASTER & START SLAVE do not reset error columns in SHOW
SLAVE STATUS". Now these reset the errors.
I extended the task to cleaning error messages, making them look nicer,
and making the output of SHOW SLAVE STATUS (column Last_error) be as complete
as what's printed on the .err file;
previously we would have, for a failure of a replicated LOAD DATA INFILE:
- in the .err, 2 lines:
"duplicate entry 2708 for key 1"
"failed loading SQL_LOAD-5-2-2.info"
- and in SHOW SLAVE STATUS, only:
"failed loading SQL_LOAD-5-2-2.info".
Now SHOW SLAVE STATUS will contain the concatenation of the 2 messages.
and other replicate-*-table options in SHOW SLAVE STATUS.
Seems like it had not been done, so I push it now:
there's 4 new columns to SHOW SLAVE STATUS.
Added MAX_PASSWORD_LENGTH. This increased master-slave passwords to 32 bytes (Bug #766)
Fixed server crash on purge master logs or show master logs when binlog is off. (Bug #733)
- 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.
we now make a distinction between if the master is < 3.23.57, 3.23 && >=57, and 4.x
(before the 2 3.23 were one). This is because in 3.23.57 we have a way to distinguish between
a Start_log_event written at server startup and one written at FLUSH LOGS, so we
have a way to know if the slave must drop old temp tables or not.
Change: mi->old_format was bool, now it's enum (to handle 3 cases). However, functions
which had 'bool old_format' as an argument have their prototypes unchanged, because
the old old_format == 0 now corresponds to the enum value BINLOG_FORMAT_CURRENT which
is equal to 0, so boolean tests are left untouched. The only case were we use mi->old_format
as an enum instead of casting it implicitly to a bool, is in Start_log_event::exec_event,
where we want to distinguish between the 3 possible enum values.
Call pthread_mutex_destroy() on not used mutex.
Changed comments in .h and .c files from // -> /* */
Added detection of mutex on which one didn't call pthread_mutex_destroy()
Fixed bug in create_tmp_field() which causes a memory overrun in queries that uses "ORDER BY constant_expression"
Added optimisation for ORDER BY NULL
Fixed comparision of log-binary name to handle comparison when file name extension wraps from .999 to .1000
Don't replicate CREATE/DROP DATABASE if wild_xxx_table=database.% is used.
Improve mysql-test to be more robust.
Fix that GRANT doesn't delete SSL options
Change innobase_flush_log_at_trx_commit to uint.
Don't rotate logs if we read a rotate log entry from the master.
Changed option variables to my_bool (to avoid bugs in my_getopt())
Added new thread specific mutex LOCK_delete to be able to free LOCK_thread_count early.
Changed usage of LOCK_thread_count -> LOCK_status for statistics variables
More DBUG info for replication
Better error messages from replication
Fixed bug in replication code when connecting to 'localhost' (time was not released properly)
Block ALARM signal on Linux for signal handler thread (Fixes problem with running mysqld with --debug)
Removed warning when setting an AUTO_INCREMENT field to NULL
Fixed bugs in my last changeset that made MySQL hard to compile.
Added mutex around some data that could cause table cache corruptions when using OPTIMIZE TABLE / REPAIR TABLE or automatic repair of MyISAM tables.
Added mutex around some data in the slave start/stop code that could cause THD linked list corruptions
Extended my_chsize() to allow one to specify a filler character.
Extend vio_blocking to return the old state (This made some usage of this function much simpler)
Added testing for some functions that they caller have got the required mutexes before calling the function.
Use setrlimit() to ensure that we can write core file if one specifies --core-file.
Added --slave-compressed-protocol
Made 2 the minimum length for ft_min_word_len
Added variables foreign_key_checks & unique_checks.
Less logging from replication code (if not started with --log-warnings)
Changed that SHOW INNODB STATUS requre the SUPER privilege
More DBUG statements and a lot of new code comments
(All commit emails since 4.0.1 checked)
This had to be done now, before the 4.1 tree changes to much, to make it easy to propagate bug fixes to the 4.1 tree.
