CREATE DATABASE statement used the current database instead of the
database created when checking conditions for replication.
CREATE/DROP/ALTER DATABASE statements are now replicated based on
the manipulated database.
insertion of new records partially failed. It would get logged because of the
logic to log a partially-failed 'INSERT ... SELECT' (which can't be rolled back
in non-transactional tables), but 'CREATE TABLE ... SELECT' is always rolled
back on failure, even for non-transactional tables. (Bug #6682)
(Original fix reimplemented after review by Serg and Guilhem.)
Added auto-correct of field length for enum/set tables for ALTER TABLE
This is becasue of a bug in previous MySQL 4.1 versions where the length for enum/set was set incorrectly after ALTER TABLE
- add_field_to_list() now uses <List>String
instead of TYPELIB to be able to distinguish
literals 'aaa' and hex literals 0xaabbcc.
- move some code from add_field_to_list() where
we don't know column charset yet, to
mysql_prepare_table(), where we do.
When we are writing a transaction to the binlog, we log BEGIN/COMMIT with zero error code.
Example: all statements of trans succeeded, connection lost and so implicit rollback:
we don't want ER_NET* errors to be logged in the BEGIN/ROLLBACK events, while statement
events have 0. If there was really a serious error code, it's already in the statement events.
Added push_back(void *, MEM_ROOT *) to make some list-handling code easier that needs to be allocated in a different mem-root
(Before one had to change thd->mem_root ; push_back(); restore mem_root.
The idea of the fix is that the administrative statements
OPTIMIZE TABLE, REPAIR TABLE and ANALYZE TABLE should not
generate binlog errors if there is no errors on the master.
FOUND is not a reserved keyword anymore
Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted
Added 'simple_select' method to be able to quickly determinate if a select_result is a normal SELECT
Note that the 5.0 tree is not yet up to date: Sanja will have to fix multi-update-locks for this merge to be complete
Added a try to a normal repair() if repair_by_sort() failed.
This was not done with ENABLE KEYS and OPTIMIZE TABLE.
Fixed error code handling in mysql_alter_table().

to auto_increment in 4.1".
Now we are enforcing NO_AUTO_VALUE_ON_ZERO mode during ALTER TABLE only
if we are converting one auto_increment column to another auto_increment
column (this also includes most common case when we don't do anything
with such column).
Also now when we convert some column to TIMESTAMP NOT NULL column with
ALTER TABLE we convert NULL values to current timestamp, (as we do this
in INSERT). One can still get old behavior by setting system TIMESTAMP
variable to 0.
More tests.
Better error messages.
Fixed bug when checking if we updated all needed columns for INSERT.
Give an error if we encounter a wrong float value during parsing.
Don't print DEFAULT for columns without a default value in SHOW CREATE/SHOW FIELDS.
Fixed UPDATE IGNORE when using STRICT mode.
column types TIMESTAMP is NOT NULL by default, so in order to have
TIMESTAMP column holding NULL valaues you have to specify NULL as
one of its attributes (this needed for backward compatibility).
Main changes:
Replaced TABLE::timestamp_default_now/on_update_now members with
TABLE::timestamp_auto_set_type flag which is used everywhere
for determining if we should auto-set value of TIMESTAMP field
during this operation or not. We are also use Field_timestamp::set_time()
instead of handler::update_timestamp() in handlers.
