Detailed Description

Try and determine the index root pages by checking if the next/prev pointers are both FIL_NULL. We need to ensure that skip deleted pages.

Check if the .ibd file row format is the same as the table's.

Parameters

ibd_table_flags

- determined from space and page.

Returns

DB_SUCCESS or error code.

Return values

the	space id of the tablespace being iterated over

Implements PageCallback.

dberr_t FetchIndexRootPages::operator() ( os_offset_t  offset, buf_block_t *  block  )

virtual

Called for each block as it is read from the file.

Parameters

offset	- physical offset in the file
block	- block to convert, it is not from the buffer pool.

Return values

DB_SUCCESS

or error code.

Called for each block as it is read from the file. Check index pages to determine the exact row format. We can't get that from the tablespace header flags alone.

Parameters

offset	- physical offset in the file
block	- block to convert, it is not from the buffer pool.

Return values

DB_SUCCESS

or error code.

Implements PageCallback.
