This was reported as Issue #381. buf_page_set_old(): Assert that blocks may only be set old if buf_pool->LRU_old is initialized and buf_pool->LRU_old_len is nonzero. Assert that buf_pool->LRU_old points to the block at the old/new boundary. buf_LRU_old_adjust_len(): Invoke buf_page_set_old() after adjusting buf_pool->LRU_old and buf_pool->LRU_old_len, in order not to violate the added assertions. buf_LRU_old_init(): Replace buf_page_set_old() with a direct assignment to bpage->old, because these loops that initialize all the blocks would temporarily violate the assertions about buf_pool->LRU_old. buf_LRU_remove_block(): When setting buf_pool->LRU_old = NULL, also clear all bpage->old flags and set buf_pool->LRU_old_len = 0. buf_LRU_add_block_to_end_low(), buf_LRU_add_block_low(): Move the buf_page_set_old() call later in order not to violate the debug assertions. If buf_pool->LRU_old is NULL, set old=FALSE. buf_LRU_free_block(): Replace the UNIV_LRU_DEBUG assertion with a dummy buf_page_set_old() call that performs more thorough checks. buf_LRU_validate(): Do not tolerate garbage in buf_pool->LRU_old_len even if buf_pool->LRU_old is NULL. Check that bpage->old is monotonic. buf_relocate(): Make the UNIV_LRU_DEBUG checks stricter. buf0buf.h: Revise the documentation of buf_page_t::old and buf_pool_t::LRU_old_len. |
