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
Indeed now that stored procedures CALL is not binlogged, but instead the invoked substatements are,
the restrictions applied by log-bin-trust-routine-creators=0 are superfluous for procedures.
They still need to apply to functions where function calls are written to the binlog (for example as "DO myfunc(3)").
We rename the variable to log-bin-trust-function-creators but allow the old name until some future version (and issue a warning if old name is used).
Option to set environment variable MTR_BUILD_THREAD to a small
number, from what mysql-test-run calculate port numbers that
will not conflict with other runs with different thread num
Added flag to Field::store(longlong) to specify if value is unsigned.
This fixes bug #12750: Incorrect storage of 9999999999999999999 in DECIMAL(19, 0)
Fixed warning from valgrind in CREATE ... SELECT
Fixed double free of mysql.options if reconnect failed
- Fixed problem, only detect comment if the # is on start of line AND starting line of the current command.
- Wrote tests for most of the mysqltest commands, added stricter checking of correct syntax.
Added a sleep for 5 seconds when shuting down,
work around for strange problem with server restarts
