use the Alter_inplace_info::ALTER_COLUMN_OPTION flag if
field/column flags were altered.
change ha_example to use check_if_supported_inplace_alter() instead
of obsolete check_if_incompatible_data()

message:
Bug#17647863: MYSQL DOES NOT COMPILE ON OSX 10.9 GM
Rename test() macro to MY_TEST() to avoid conflict with libc++.
Cleanups:
* remove unused HA_EXTRA_EXPORT (can be added later if needed, e.g. for Aria)
* clarify the meaning of HA_CAN_EXPORT
* make all engines that support EXPORT to announce it
* reduce code duplication
Syntax. Server support. Test cases.
InnoDB bugfixes:
* don't mess around with system sprintf's, always use my_error() for errors.
* don't use InnoDB internal error codes where OS error codes are expected.
* don't say "file not found", when it was.
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()

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

More DBUG
support ha_innodb.so as a dynamic plugin.
* remove obsolete *,innodb_plugin.rdiff files
* s/--plugin-load=/--plugin-load-add=/
* MYSQL_PLUGIN_IMPORT glob_hostname[]
* use my_error instead of push_warning_printf(ER_DEFAULT)
* don't use tdc_size and tc_size in a module
update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10)
* copy new tests over
* disable some tests for (old) InnoDB
* delete XtraDB tests that no longer apply
small compatibility changes:
* s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/
* revert unnecessary InnoDB changes to make it a bit closer to the upstream
fix XtraDB to compile on Windows (both as a static and a dynamic plugin)
disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5)
storage/innobase/handler/ha_innodb.cc:
revert few unnecessary changes to make it a bit closer to the original InnoDB
storage/innobase/include/univ.i:
correct the version to match what it was merged from
extend table names discovery (ha_discover_table_names() and Discovered_table_list) to return
or optionally filter out temporary tables ("#sql..."). SHOW commands and I_S tables
typically want temp table filtered out, while DROP DATABASE wants to see them too.
additonally, remove the supression for the warning "Invalid (old?) table or database name"
from mtr, and add it to .test files as needed (we need to test that this warning
does *not* happen in drop.test)
- The crash was caused because the optimizer called handler->multi_range_read_info()
on a derived temporary table. That table has been created, but not opened yet.
Because of that, handler::table was NULL, which caused crash.
Fixed by changing DS-MRR methods to use handler::table_share instead.
handler::table_share is set in handler ctor, so this should be safe.
remove unused HA_CAN_EXPORT
(with the merge of "FLUSH TABLE <table_list> FOR EXPORT",
this functionality should be added back, but differently -
no table flag, handler::extra() returns an error instead)
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
Backport the fix olav.sandstaa@sun.com-20101102184747-qfuntqwj021imy9r:
"Fix for Bug#52660 Perf. regr. using ICP for MyISAM on range queries on an index containing TEXT"
(together with further fixes in that code) into MyISAM and Aria.
1. DROP DATABASE should use ha_discover_table_names(), not look at .frm files.
2. filename_to_tablename() also encodes temp file names #sql- -> #mysql50##sql
3. no special treatment for #sql- files, no TABLE_LIST::internal_tmp_table
4. discover also table file names, that start from #
Partitioning didn't store the name of default storage engine for partitions
in the frm file - it only store the typecode. Typecodes aren't stable, and
might vary depending on the order in which storage engines are loaded (can
be changed even from my.cnf without recompilation).
As a temporary workaround for 5.5, we hard-code Aria's typecode, to make sure it
never changes.
