Problem:
=======
- During inplace algorithm, concurrent DML fails to write
the log operation into the temporary file. InnoDB fail to
mark the error for the online log.
- ddl_log_write() releases the global ddl lock prematurely before
release the log memory entry
Fix:
===
row_log_online_op(): Mark the error in online log when
InnoDB ran out of temporary space
fil_space_extend_must_retry(): Mark the os_has_said_disk_full
as true if os_file_set_size() fails
btr_cur_pessimistic_update(): Return error code when
btr_cur_pessimistic_insert() fails
ddl_log_write(): Release the global ddl lock after releasing the
log memory entry when error was encountered
btr_cur_optimistic_update(): Relax the assertion that
blob pointer can be null during rollback because InnoDB can
ran out of space while allocating the external page
row_undo_mod_upd_exist_sec(): Remove the assertion which says
that InnoDB should fail to build index entry when rollbacking
an incomplete transaction after crash recovery. This scenario
can happen when InnoDB ran out of space.
row_upd_changes_ord_field_binary_func(): Relax the assertion to
make that externally stored field can be null when InnoDB ran out
of space.
