- -/*********************************************************************** - This function implements ICP for I_S.INNODB_CHANGED_PAGES by parsing a - condition and getting lower and upper bounds for start and end LSNs if the - condition corresponds to a certain pattern. - - In the most general form, we understand queries like - - SELECT * FROM INNODB_CHANGED_PAGES - WHERE START_LSN > num1 AND START_LSN < num2 - AND END_LSN > num3 AND END_LSN < num4; - - That's why the pattern syntax is: - - pattern: comp | and_comp; - comp: lsn < int_num | lsn <= int_num | int_num > lsn | int_num >= lsn; - lsn: start_lsn | end_lsn; - and_comp: expression AND expression | expression AND and_comp; - expression: comp | any_other_expression; - - The two bounds are handled differently: the lower bound is used to find the - correct starting _file_, the upper bound the last _block_ that needs reading. - - Lower bound conditions are handled in the following way: start_lsn >= X - specifies that the reading must start from the file that has the highest - starting LSN less than or equal to X. start_lsn > X is equivalent to - start_lsn >= X + 1. For end_lsn, end_lsn >= X is treated as - start_lsn >= X - 1 and end_lsn > X as start_lsn >= X. - - For the upper bound, suppose the condition is start_lsn < 100, this means we - have to read all blocks with start_lsn < 100. Which is equivalent to reading - all the blocks with end_lsn <= 99, or just end_lsn < 100. That's why it's - enough to find maximum lsn value, doesn't matter if this is start or end lsn - and compare it with "start_lsn" field. LSN <= 100 is treated as LSN < 101. - - Example: - - SELECT * FROM INNODB_CHANGED_PAGES - WHERE - start_lsn > 10 AND - end_lsn <= 1111 AND - 555 > end_lsn AND - page_id = 100; - - end_lsn will be set to 555, start_lsn will be set 11. - - Support for other functions (equal, NULL-safe equal, BETWEEN, IN, etc.) will - be added on demand. - -*/ -static -void -limit_lsn_range_from_condition( -/*===========================*/ - TABLE* table, /*!<in: table */ - Item* cond, /*!<in: condition */ - ib_uint64_t* start_lsn, /*!<in/out: minumum LSN */ - ib_uint64_t* end_lsn) /*!<in/out: maximum LSN */ -{ - enum Item_func::Functype func_type; - - if (cond->type() != Item::COND_ITEM && - cond->type() != Item::FUNC_ITEM) - return; - - func_type = ((Item_func*) cond)->functype(); - - switch (func_type) - { - case Item_func::COND_AND_FUNC: - { - List_iterator<Item> li(*((Item_cond*) cond) - ->argument_list()); - Item *item; - - while ((item= li++)) { - limit_lsn_range_from_condition(table, item, start_lsn, - end_lsn); - } - break; - } - case Item_func::LT_FUNC: - case Item_func::LE_FUNC: - case Item_func::GT_FUNC: - case Item_func::GE_FUNC: - { - Item *left; - Item *right; - Item_field *item_field; - ib_uint64_t tmp_result; - ibool is_end_lsn; - - /* a <= b equals to b >= a that's why we just exchange "left" - and "right" in the case of ">" or ">=" function.
