Add typecasts to ulong because ulint is __int64 in Win 64-bits
Better error message to the .err log if we have to crash the server because the buffer pool is exhausted by the lock table or the adaptive hash index
Protect the reading of the latest foreign key error explantion buffer with a mutex; in theory, a race condition could cause SHOW INNODB STATUS print garbage characters after the error info; remove the sprintf of the latest UNIQUE KEY error, since the buffer really was always empty
Remove unused function btr_cur_update_sec_rec_in_place; besides, it was faulty, because even if strings are alphabetically identified, they can have different lengths
Fix bug: in a FOREIGN KEY, ON UPDATE CASCADE was not triggered if the update changed a string to another value identical in alphabetical ordering, e.g., abc -> aBc
Change some inline functions to normal functions, so that they can be called in ha_innodb.cc; this removes the the remaining linking problems reported by Paul DuBois
Multiple charset support for InnoDB; note that if you create tables and the default charset-collation is not latin1_swedish_ci, then you cannot use those tables if you downgrade to 4.0 again
Added more DBUG statements
Ensure that we are comparing end space with BINARY strings
Use 'any_db' instead of '' to mean any database. (For HANDLER command)
Only strip ' ' when comparing CHAR, not other space-like characters (like \t)
Allow always DROPping of a table which is only referenced by FOREIGN KEY constraints from the same table
Many files:
Do not let REPLACE to perform internally an UPDATE if the table is referenced by a FOREIGN KEY: the manual says that REPLACE must resolve a duplicate key error semantically with DELETE(s) + INSERT, and not by an UPDATE; the internal update caused foreign key checks and cascaded operations to behave in a semantically wrong way
Fix bug #2167: generate foreign key id's locally for each table, in the form databasename/tablename_ibfk_number; if the user gives the constraint name explicitly remember it; these changes should ensure that foreign key id's in a slave are the same as in the master, and DROP FOREIGN KEY does not break replication
sync0sync.c:
UNIV_SYNC_DEBUG caused assertion in the creation of the doublewrite buffer, if we do not allow thousands of latches per thread
DROP DATABASE now assumes RAID directories are in hex. (Bug #2627)
Don't increment 'select_full_range' and similar statistics for EXPLAIN queries. (Bug #2506)
Test in configure if pthread_key_delete() exists (to fix compile problem on SCO) (Bug #2461)
Change print format of FOREIGN KEY constraints spanning multiple databases to <backquote>databasename<backquote>.<backquote>tablename<backquote>; but when parsing them we must also accept <backquote>databasename.tablename<backquote>, because that was the output format in < 4.0.18
Change print format of FOREIGN KEY constraints spanning multiple databases to: .; but we when parsing them we must also accept , because that was the output format in < 4.0.18
Remove redundant code; parse both the database name and the table name in a FOREIGN KEY constraint with quotes in mind
row0mysql.c, ha_innodb.cc, sql_table.cc:
Return error message Cannot delete or update a parent row... if we try to drop a table which is referenced by a FOREIGN KEY constraint, and the user has not set foreign_key_checks=0
Fix bug #2483 with InnoDB, UNIQUE secondary index, and NULL values in that unique index; with the IS NULL predicate, InnoDB returned only the first matching row, though there can be many
