- Added better error messages when trying to open a table that can't be discovered or unpacked. The most likely cause of this is that it does not have any frm data, probably since it has been created from NdbApi or is a NDB system table.
- Separated functionality that was in ha_create_table_from_engine into two functions. One that checks if the table exists and another one that tries to create the table from the engine.
Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable
1.) Added a new option to mysql_lock_tables() for ignoring FLUSH TABLES.
Used the new option in create_table_from_items().
It is necessary to prevent the SELECT table from being reopend.
It would get new storage assigned for its fields, while the
SELECT part of the command would still use the old (freed) storage.
2.) Protected the CREATE TABLE and CREATE TABLE ... SELECT commands
against a global read lock. This prevents a deadlock in
CREATE TABLE ... SELECT in conjunction with FLUSH TABLES WITH READ LOCK
and avoids the creation of new tables during a global read lock.
3.) Replaced set_protect_against_global_read_lock() and
unset_protect_against_global_read_lock() by
wait_if_global_read_lock() and start_waiting_global_read_lock()
in the INSERT DELAYED handling.
Count null_bits separately from field offsets and adjust them in case of primary key parts.
(Previously a CREATE TABLE with a lot of null fields that was part of a primary key caused MySQL to wrongly count the number of bytes needed to store null bits)
This is a more complete bug fix for #6236
if we fall back to mysql_alter_table() (for InnoDB), don't do binlogging in mysql_alter_table(), as mysql_admin_table()
is not supposed to do any binlogging (it is done by the caller).
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.
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.
