Marko Mäkelä 112df06996 MDEV-15529 IMPORT TABLESPACE unnecessarily uses the doublewrite buffer ... fil_space_t::atomic_write_supported: Always set this flag for TEMPORARY TABLESPACE and during IMPORT TABLESPACE. The page writes during these operations are by definition not crash-safe because they are not written to the redo log. fil_space_t::use_doublewrite(): Determine if doublewrite should be used. buf_dblwr_update(): Add assertions, and let the caller check whether doublewrite buffering is desired. buf_flush_write_block_low(): Disable the doublewrite buffer for the temporary tablespace and for IMPORT TABLESPACE. fil_space_set_imported(), fil_node_open_file(), fil_space_create(): Initialize or revise the space->atomic_write_supported flag. buf_page_io_complete(), buf_flush_write_complete(): Add the parameter dblwr, to indicate whether doublewrite was used for writes. buf_dblwr_sync_datafiles(): Remove an unnecessary flush of persistent tablespaces when flushing temporary tablespaces. (Move the call to buf_dblwr_flush_buffered_writes().)		2018-03-10 11:54:34 +02:00
