Tested for 2, 63, 64, 65, 127, 128, 129, 255, 256, and 257 indexes.
Testing this part of the bugfix requires rebuilding of the server
with different options. This cannot be done with our test suite.
Therefore I added the necessary test files to the bug report.
If you repeat the tests, please note that the ps_* tests fail for
everything but 64 indexes. This is because of differences in the

The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
object and open a handler to the table object
Other noteworthy changes:
- In TABLE_SHARE the most common strings are now LEX_STRING's
- Better error message when table is not found
- Variable table_cache is now renamed 'table_open_cache'
- New variable 'table_definition_cache' that is the number of table defintions that will be cached
- strxnmov() calls are now fixed to avoid overflows
- strxnmov() will now always add one end \0 to result
- engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
- After creating a field object one must call field->init(table) before using it
- For a busy system this change will give you:
- Less memory usage for table object
- Faster opening of tables (if it's has been in use or is in table definition cache)
- Allow you to cache many table definitions objects
- Faster drop of table

instead of BLOB

Assert if new not handled cast type

sql/sql_acl.cc:

sql/sql_base.cc:
Main implementation of table definition cache
(The #ifdef's are there for the future when table definition cache will replace open table cache)
Now table definitions are cached indepndent of open tables, which will speed up things when a table is in use at once from several places
Views are not yet cached; For the moment we only cache if a table is a view or not.
Faster implementation of find_temorary_table()
Replace 'wait_for_refresh()' with the more general function 'wait_for_condition()'
Drop table is slightly faster as we can use the table definition cache to know the type of the table

table_cache_key and table_name are now LEX_STRING
'sDBUG print fixes

Replace some fn_format() with faster unpack_filename().
Safer strxnmov()
part_info is now in TABLE
Added Mikaels patch for partition and ALTER TABLE
Instead of using 'TABLE_SHARE->is_view' use 'table_flags() & HA_NO_COPY_ON_ALTER

sql/sql_view.cc:
safer strxnmov()
Create common TABLE_SHARE object for views to allow us to cache if table is a view
sql/structs.h:
Added SHOW_TABLE_DEFINITIONS
sql/table.cc:
Creation and destruct of TABLE_SHARE objects that are common for many TABLE objects
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
object and open a handler to the table object
open_table_def() is written in such a way that it should be trival to add parsing of the .frm files in new formats
sql/table.h:
TABLE objects for the same database table now share a common TABLE_SHARE object
In TABLE_SHARE the most common strings are now LEX_STRING's
sql/unireg.cc:
Changed arguments to rea_create_table() to have same order as other functions
Call field->init(table) for new created fields
sql/unireg.h:
Added OPEN_VIEW
strings/strxnmov.c:
Change strxnmov() to always add end \0
This makes usage of strxnmov() safer as most of MySQL code assumes that strxnmov() will create a null terminated string
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
object and open a handler to the table object
Other noteworthy changes:
- In TABLE_SHARE the most common strings are now LEX_STRING's
- Better error message when table is not found
- Variable table_cache is now renamed 'table_open_cache'
- New variable 'table_definition_cache' that is the number of table defintions that will be cached
- strxnmov() calls are now fixed to avoid overflows
- strxnmov() will now always add one end \0 to result
- engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
- After creating a field object one must call field->init(table) before using it
- For a busy system this change will give you:
- Less memory usage for table object
- Faster opening of tables (if it's has been in use or is in table definition cache)
- Allow you to cache many table definitions objects
- Faster drop of table
