New prototype for get_auto_increment() (but new arguments not yet used), to be able
to reserve a finite interval of auto_increment values from cooperating engines.
A hint on how many values to reserve is found in handler::estimation_rows_to_insert,
filled by ha_start_bulk_insert(), new wrapper around start_bulk_insert().
NOTE: this patch changes nothing, for all engines. But it makes the API ready for those
engines which will want to do reservation.
More csets will come to complete WL#3146.
duplicate fields removed, st_mysql_storage_engine added to support
run-time handlerton initialization (no compiler warnings), handler API
is now tied to MySQL version, handlerton->plugin mapping added
(slot-based), dummy default_hton removed, plugin-type-specific
initialization generalized, built-in plugins are now initialized too,
--default-storage-engine no longer needs a list of storage engines
in handle_options().
mysql-test-run.pl bugfixes
The problem was that the optimize code was not closing both the reader and writer streams before attempting
to rename the file. This will not work on Windows where all file handles have to be closed before the
file can be renamed, moved, or deleted. The fix was to move the close calls before the rename.
We return the error code from my_rename in case of failure but we attempt to reopen the writers and readers
even in the case of failure so that the table can still be usable.
