Implementation of MDEV-5491: CREATE OR REPLACE TABLE
Using CREATE OR REPLACE TABLE is be identical to
DROP TABLE IF EXISTS table_name;
CREATE TABLE ...;
Except that:
* CREATE OR REPLACE is be atomic (now one can create the same table between drop and create).
* Temporary tables will not shadow the table name for the DROP as the CREATE TABLE tells us already if we are using a temporary table or not.
* If the table was locked with LOCK TABLES, the new table will be locked with the same lock after it's created.
Implementation details:
- We don't anymore open the to-be-created table during CREATE TABLE, which the original code did.
- There is no need to open a table we are planning to create. It's enough to check if the table exists or not.
- Removed some of duplicated code for CREATE IF NOT EXISTS.
- Give an error when using CREATE OR REPLACE with IF NOT EXISTS (conflicting options).
- As a side effect of the code changes, we don't anymore have to internally re-prepare prepared statements with CREATE TABLE if the table exists.
- Made one code path for all testing if log table are in use.
- Better error message if one tries to create/drop/alter a log table in use
- Added back disabled rpl_row_create_table test as it now seams to work and includes a lot of interesting tests.
- Added HA_LEX_CREATE_REPLACE to mark if we are using CREATE OR REPLACE
- Aligned CREATE OR REPLACE parsing code in sql_yacc.yy for TABLE and VIEW
- Changed interface for drop_temporary_table() to make it more reusable
- Changed Locked_tables_list::init_locked_tables() to work on the table object instead of the table list object. Before this it used a mix of both, which was not good.
- Locked_tables_list::unlock_locked_tables(THD *thd) now requires a valid thd argument. Old usage of calling this with 0 i changed to instead call Locked_tables_list::reset()
- Added functions Locked_tables_list:restore_lock() and Locked_tables_list::add_back_last_deleted_lock() to be able to easily add back a locked table to the lock list.
- Added restart_trans_for_tables() to be able to restart a transaction.
- DROP_ACL is required if one uses CREATE TABLE OR REPLACE.
- Added drop of normal and temporary tables in create_table_imp() if CREATE OR REPLACE was used.
- Added reacquiring of table locks in mysql_create_table() and mysql_create_like_table()

Create logs
mysql-test/t/create_or_replace.test:
Basic testing of CREATE OR REPLACE TABLE
mysql-test/t/partition_exchange.test:
Error number changed as we are now using same code for all log table change issues
mysql-test/t/ps_ddl.test:
Fewer reprepares with new code
sql/handler.h:
Moved things around a bit in a structure to get better alignment.
Added HA_LEX_CREATE_REPLACE to mark if we are using CREATE OR REPLACE
Added 3 elements to end of HA_CREATE_INFO to be able to store state to add backs locks in case of LOCK TABLES.
sql/log.cc:
Reimplemented check_if_log_table():
- Simpler and faster usage
- Can give error messages
This gives us one code path for allmost all error messages if log tables are in use
sql/log.h:
New interface for check_if_log_table()
sql/slave.cc:
More logging
sql/sql_alter.cc:
New interface for check_if_log_table()
sql/sql_base.cc:
More documentation
Changed interface for drop_temporary_table() to make it more reusable
Changed Locked_tables_list::init_locked_tables() to work on the table object instead of the table list object. Before this it used a mix of both, which was not good.
Locked_tables_list::unlock_locked_tables(THD *thd) now requires a valid thd argument. Old usage of calling this with 0 i changed to instead call Locked_tables_list::reset()
Added functions Locked_tables_list:restore_lock() and Locked_tables_list::add_back_last_deleted_lock() to be able to easily add back a locked table to the lock list.
Check for command number instead of open_strategy of CREATE TABLE was used.
Added restart_trans_for_tables() to be able to restart a transaction. This was needed in "create or replace ... select" between the drop table and the select.
sql/sql_base.h:
Added and updated function prototypes
sql/sql_class.h:
Added new prototypes to Locked_tables_list class
Added extra argument to select_create to avoid double call to eof() or send_error()
- I needed this in some edge case where the table was not created against expections.
sql/sql_db.cc:
New interface for check_if_log_table()
sql/sql_insert.cc:
Remember position to lock information so that we can reaquire table lock for LOCK TABLES + CREATE OR REPLACE TABLE SELECT. Later add back the lock by calling restore_lock().
Removed one not needed indentation level in create_table_from_items()
Ensure we don't call send_eof() or abort_result_set() twice.
sql/sql_lex.h:
Removed variable that I temporarly added in an earlier changeset
sql/sql_parse.cc:
Removed old test code (marked with QQ)
Ensure that we have open_strategy set as TABLE_LIST::OPEN_STUB in CREATE TABLE
Removed some IF NOT EXISTS code as this is now handled in create_table_table_impl().
Set OPTION_KEEP_LOGS later. This code had to be moved as the test for IF EXISTS has changed place.
DROP_ACL is required if one uses CREATE TABLE OR REPLACE.
sql/sql_partition_admin.cc:
New interface for check_if_log_table()
sql/sql_rename.cc:
New interface for check_if_log_table()
sql/sql_table.cc:
New interface for check_if_log_table()
Moved some code in mysql_rm_table() under a common test.
- Safe as temporary tables doesn't have statistics.
- !is_temporary_table(table) test was moved out from drop_temporary_table() and merged with upper level code.
- Added drop of normal and temporary tables in create_table_imp() if CREATE OR REPLACE was used.
- Added reacquiring of table locks in mysql_create_table() and mysql_create_like_table()
- In mysql_create_like_table(), restore table->open_strategy() if it was changed.
- Re-test if table was a view after opening it.
sql/sql_table.h:
New prototype for mysql_create_table_no_lock()
sql/sql_yacc.yy:
Added syntax for CREATE OR REPLACE TABLE
Reuse new code for CREATE OR REPLACE VIEW
sql/table.h:
Added name for enum type
sql/table_cache.cc:
More DBUG
