Merge InnoDB-4.0.14: SAVEPOINT now implemented; InnoDB now accepts also column prefix keys; crashing bug in ON UPDATE CASCADE fixed; page checksum formula fixed
Add syntax SAVEPOINT id and ROLLBACK TO SAVEPOINT id. This is compatible with DB2 and Oracle but not with SQL Server. Savepoints do not do anything yet, this is just parsing.
now by default, FLUSH, OPTIMIZE, ANALYZE, REPAIR commands are written to the
binlog, unless the new NO_WRITE_TO_BINLOG keyword was used :
OPTIMIZE NO_WRITE_TO_BINLOG table t;
Previously these commands were never written to the binlog, but there are
2 reasons to change this :
- the RENAME TABLE in MERGE table bug (#175) on slave
- the possible "differently optimised queries may lead to different
updates on the master and slave" bug, until we have automatic ORDER BY.
FLUSH LOGS/SLAVE/MASTER/TABLES WITH READ LOCK are never written to the binlog.
New test for the new logging behaviour.
Other small change : reload_acl_and_cache() and reset_slave() don't send their errors themselves,
this is more usual.
Very nasty bug.
It was caused by double free()-ing memory of join->select and
join->quick.
I was able to pinpoint it only after using Valgrind.
Plus better fix for bug with TMP_TABLE_PARAM.
Plus new constructor for SELECT_LEX.
this implementation have limitation: prohibited subselect in ORDER BY dependence of most outer query (will be solved after removing passing first select_lex as fake select for global mysql_select())
Expanded the mysql.proc table, reworked the find/create/drop functions
completely, added new functions for FUNCTIONs (lotta functions here :),
got rid of some unnecessary use of Item_strings while at it. Extended
the parser correspondingly, and fiddled around a bit to make SP FUNCTIONs
coexist with UDFs.
Can now CREATE and DROP FUNCTIONs. Invoking yet to come...
Added:
PURGE [MASTER] LOGS BEFORE date/date_expression
expire-logs-days option
With this option old files are deleted when
- mysqld is started
- log is rotated
- someone does FLUSH LOGS
Portability fixes
Added new client function: mysql_get_server_version()
New server help code (From Victor Vagin)
Fixed wrong usage of binary()
Disabled RTREE usage for now.
