HEAP: Copies the key count to a backup variable and sets the key count to zero.
That way, no HEAP function will ever try to touch any index.
Re-enabling is done by copying back the backup variable.
To avoid memory leak at table close, disable deletes all index trees.
Re-enabling must be done with empty indexes and data anyway. Otherwise,
the indexes would need to be repaired, wich HEAP is not capable of.
MyISAM: Only the key_map is cleared and set.
Re-enabling must be done with empty indexes and data. Otherwise, repair needs
to be done which will enable all keys persistently.
The former implementation disabled only non-unique keys and maked this persistent.
The new implementation additionally can disable all keys, but only without
making this persistent. Re-enabling all keys can be done without repair,
if data file and indexes are empty.

sql/sql_yacc.yy:
Hand-merged
This is to enable table handlers to implement online create/drop index.
It consists of some parts:
- New default handler methods in handler.h
- Split of mysql_alter_table. It decides if only one kind of
alteration is to be done (e.g. only create indexes or only drop
indexes etc.) It then calls the specialized new handler method if
the handler implements it. Otherwise it calls real_alter_table.
- The parser sets flags for each alter operation detected in a
command. These are used by mysql_alter_table for the decision.
- mysql_prepare_table is pulled out of mysql_create_table. This is
also used by mysql_create_index to prepare the key structure array
for the handler. It is also used by mysql_create_index and
mysql_drop_index to prepare a call to mysql_create_frm.
- mysql_create_frm is pulled out of rea_create_table for use by
mysql_create_index and mysql_drop_index after the index is
created/dropped.
Thanks to Antony who supplied most of the changes.
sql/handler.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
New virtual handler methods with default implementation and return flags.
sql/mysql_priv.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
New function prototypes. mysql_prepare_table is pulled out of
mysql_create_table. It prepares a table structure, which is used by
mysql_create_table, mysql_create_index and mysql_drop_index.
real_alter_table is pulled out of mysql_alter_table. The latter only
looks if the requested operation can be done by specialized functions
or else calls real_alter_table, which does the real thing.
mysql_add_column and mysql_drop_colunm are for future use. They simply
call real_alter_table. mysql_create_frm is pulled out of
rea_create_table. It is called also from mysql_create_index and
mysql_drop_index after successful create/drop index.
mysql_alter_table prototype is extended by the new alter_flags argument.
sql/sql_base.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_create_index and mysql_drop_index moved to sql_table.cc.

sql/sql_table.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_prepare_table is pulled out of mysql_create_table.
mysql_create_index and mysql_drop_index are changed so that they use
the new handler functions if the handler implements them.
mysql_add_column and mysql_drop_column are for future use. They simply
call real_alter_table. mysql_alter_table only decides which function
to use for the requested operation. real_alter_table implements most
of what mysql_alter_table did before.
sql/sql_yacc.yy:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
Set the alter_flags where appropriate.

when we open the HEAP table for the first time since server restart,
in hp_open(), we set a flag to propagate this info to the handler level
which then writes a DELETE FROM this_heap_table to the binlog.
It is not a perfect solution for the bug, because between the server start and
the first open of the table, the slave still had old data in his table so
a SELECT on the slave may show wrong content. But if there is a --init-file
to populate the HEAP table on master as startup, then this is a safe fix
(I'll put a note about init-file in the HEAP section of the manual).
heap/hp_info.c:
new info variable implicit_emptied
heap/hp_open.c:
If this is the first open of the HEAP table, it means it is empty,
so we mark it.
include/heap.h:
new variables implicit_emptied
(we need one in HEAPINFO for the hp_info() call).
sql/ha_heap.cc:
report info to upper level
sql/handler.h:
new info 'implicit_emptied' in the handler level; only HEAP uses it.
sql/sql_base.cc:
When a HEAP table is opened for the first time, write a DELETE FROM to the binlog,
for replication and mysqlbinlog|mysql.
Monty: I added the
entry->file->implicit_emptied= 0;
when we open the HEAP table for the first time since server restart,
in hp_open(), we set a flag to propagate this info to the handler level
which then writes a DELETE FROM this_heap_table to the binlog.
It is not a perfect solution for the bug, because between the server start and
the first open of the table, the slave still had old data in his table so
a SELECT on the slave may show wrong content. But if there is a --init-file
to populate the HEAP table on master as startup, then this is a safe fix
(I'll put a note about init-file in the HEAP section of the manual).
Added support for lower_case_table_names=2, which is to be used on case insensitive file systems.
This tells MySQL to preserve the used case of filenames and database names to make it esier to move files between cases sensitive can case insensitive file systems (like Windows and Linux)
