This patch removes the SLAVESIDE_DISABLED token from the event status clause
and adds the ability to mark an event as status = SLAVESIDE_DISABLED by using
the syntax DISABLE ON SLAVE instead.
The patch also adds tests to rpl_events to check the new syntax.
This patch changes test to remove Windows-specific limitations and potential
rounding errors in the calculation of a UDF.
Also corrects a minor merge conflict.
Adding an event that can be used to denote that an incident occured
on the master. The event can be used to denote a gap in the replication
stream, but can also be used to denote other incidents.
In addition, the injector interface is extended with functions to
generate an incident event. The function will also rotate the binary
log after generating an incident event to get a fresh binary log.
This patch corrects errors that occurred in a local manual merge as a result
of updating the local repository and includes changes necessary to correct
problems found during the recalculation of next execution of events in RBR.
Fix is to rewrite the MBR::overlaps() function, to compute the dimension of both
arguments, and the dimension of the intersection; test that all three dimensions are the
same (e.g., all are Polygons).
Add tests for all MBR* functions for various combinations of shapes, lines and points.
field does not work
Fix to prevent MyISAM from reading data from NULL BLOB.
Fix to make record comparison independent of values of unused bits in
record.
Updating binlog positions in tests.
BUG#26429: SHOW CREATE EVENT is incorrect for an event that
STARTS NOW()
BUG#26431: Impossible to re-create an event from backup if its
STARTS clause is in the past
WL#3698: Events: execution in local time zone
The problem was that local times specified by the user in AT, STARTS
and ENDS of CREATE EVENT/ALTER EVENT statement were converted to UTC,
and the original time zone was forgotten. This way, event scheduler
couldn't honor Daylight Saving Time shifts, and times shown to the
user were also in UTC. Additionally, CREATE EVENT didn't allow times
in the past, thus preventing straightforward event restoration from
old backups.
This patch reworks event scheduler time computations, performing them
in the time zone associated with the event. Also it allows times to
be in the past.
The patch adds time_zone column to mysql.event table.
NOTE: The patch is almost final, but the bug#9953 should be pushed
first.
This changeset adds replication of events and user-defined functions.
There are several bug reports involved in this change:
BUG#16421, BUG#17857, BUG#20384:
This patch modifies the mysql.events table to permit the addition of
another enum value for the status column. The column now has values
of ('DISABLED','SLAVESIDE_DISABLED','ENABLED'). A status of
SLAVESIDE_DISABLED is set on the slave during replication of events.
This enables users to determine which events werereplicated from the
master and to later enable them if they promote the slave to a master.
The CREATE, ALTER, and DROP statements are binlogged.
A new test was added for replication of events (rpl_events).
BUG#17671:
This patch modifies the code to permit logging of user-defined functions.
Note: this is the CREATE FUNCTION ... SONAME variety. A more friendly error
message to be displayed should a replicated user-defined function not be
found in the loadable library or if the library is missing from the
slave.The CREATE andDROP statements are binlogged. A new test was added
for replication of user-defined functions (rpl_udf).
The patch also adds a new column to the mysql.event table named
'originator' that is used to store the server_id of the server that
the event originated on. This enables users to promote a slave to a
master and later return the promoted slave to a slave and disable the
replicated events.
Cache".
WL#1569 "Prepared Statements: implement support of Query Cache".
Prepared SELECTs did not look up in the query cache, and their results
were not stored in the query cache. This made them slower than
non-prepared SELECTs in some cases.
The fix is to re-use the expanded query (the prepared query where
"?" placeholders are replaced by their values, at execution time)
for searching/storing in the query cache.
It works fine for statements prepared via mysql_stmt_prepare(), which
are the most commonly used and were the scope of this bugfix and WL.
It works less fine for statements prepared via the SQL command
PREPARE...FROM, which are still not using the query cache if they
have at least one parameter (because then the expanded query contains
names of user variables, and user variables don't work with the
query cache, even in non-prepared queries).
Note that results from prepared SELECTs, which are in the binary
protocol, and results from normal SELECTs, which are in the text
protocol, ignore each other in the query cache, because a result in the
binary protocol should never be served to a SELECT expecting the text
protocol and vice-versa.
Note, after this patch, bug 25843 starts applying to query cache
("changing default database between PREPARE and EXECUTE of statement
breaks binlog"), we need to fix it.
1. Fixes within the testscripts (affects rpl_ddl.test and rpl_ndb_ddl.test)
- slave connection is only an observer (-> AUTOCOMMIT = 0)
This removes the problem with the hanging test around DROP DATABASE (NDB). The hanging test around DROP DATABASE is a difference to InnoDB/MyISAm behaviour but fare
away of a clear bug. IMHO this behaviour does not violate the SQL standard and should be therefore simply accepted.
- removal of wrong comments
- CREATE/DROP TEMPORARY TABLE must not cause implicit commit of the current transaction.
NDB behaves here correct and InnoDB/Falcon wrong.
- Add a missing connection slave
- Reenable the test rpl_ndb_ddl.
2. Disable rpl_ddl.test because of Bug#26418.
3. Reenable rpl_ndb_ddl.test
4. Improvements (affect rpl_ddl.test and rpl_ndb_ddl.test)
- Better + extended comments which should prevent that somebody accidently destroys the logics of the test
- Replace SELECT's printing comments by "--echo" (decreases the number of auxiliary SQL commands)
- Remove the need for include/rpl_stmt_seq2.inc (was mostly redundant to rpl_stmt_seq.inc)
- Remove extra/rpl_tests/rpl_ndb_ddl.test (corrected extra/rpl_tests/rpl_ddl.test is sufficient)
- Shift assignment of values to $show_binlog, $manipulate (variables useful for debugging) into the toplevel scripts
- The temporary tables get now their storage engine from the variable $temp_engine_type. (more deterministic testing conditions)
- Add additional protocol line if the connection is switched (was partially missing)
- Add two DML commands for comparison purposes
If we compare two items A and B, with B being (a constant) of a
larger type, then A gets promoted to B's type for comparison if
it's a constant, function, or CAST() column, but B gets demoted
to A's type if A is a (not explicitly CAST()) column. This is
counter-intuitive and not mandated by the standard.
Disabling optimisation where it would be lossy so field value
will properly get promoted and compared as binary string (rather
than as integers).
