marko a687ccdf74 branches/zip: Minor improvements. ... buf_LRU_block_remove_hashed_page(): Return the new state of the block. Only call buf_LRU_block_free_hashed_page() if buf_LRU_block_remove_hashed_page() did not return BUF_BLOCK_ZIP_FREE, that is, the control block was not freed. buf_LRU_insert_zip_clean(): New function, for inserting a compressed-only block into buf_pool->zip_clean in the LRU order. buf_LRU_block_remove_hashed_page(), buf_LRU_free_block(): Add the flag "zip" for controlling if the compressed page of an uncompressed page should be removed. For now, assume zip==TRUE. buf_LRU_get_free_block(): Replace the test for UT_LIST_GET_LEN(buf_pool->free) with a test for the return value of buf_LRU_get_free_only(). Do not free zip.data, as it must already have been freed. buf_flush_insert_into_flush_list(), buf_flush_insert_sorted_into_flush_list(): Remove compressed-only blocks from the buf_pool->zip_clean list. buf_flush_remove(): Restore compressed-only blocks to the buf_pool->zip_clean list. buf_page_init_for_read(): Uncompress compressed-only blocks when possible. Currently, there cannot be any compressed-only blocks in the buffer pool; they would be inserted by buf_LRU_free_block(bpage, zip=FALSE).		2006-12-15 15:05:18 +00:00
