WL#3071 Maria checkpoint - cleanups, simplifications - moving the construction of the "dirty pages table" into the pagecache where it belongs (because it's the pagecache which knows dirty pages). TODO: do the same soon for the "transactions table". - fix for a small bug in the pagecache (decrementation of "changed_blocks") include/pagecache.h: prototype mysys/mf_pagecache.c: m_string.h moves up for LEX_STRING to be known for pagecache.h. In pagecache_delete_page(), we must decrement "blocks_changed" even if we just delete the page without flushing it. A new function pagecache_collect_changed_blocks_with_LSN() (used by the Checkpoint module), which stores information about the changed blocks (a.k.a. "the dirty pages table") into a LEX_STRING. This function is not tested now, it will be when there is a Checkpoint. storage/maria/ma_checkpoint.c: refining the checkpoint code: factoring functions, moving the construction of the "dirty pages table" into mf_pagecache.c (I'll do the same with the construction of the "transactions table" once Serg tells me what's the best way to do it). storage/maria/ma_least_recently_dirtied.c: Simplifying the thread which does background flushing of least-recently-dirtied pages: - in first version that thread will not flush, just do checkpoints - in 2nd version, flushing should re-use existing page cache functions like flush_pagecache_blocks(). unittest/mysys/test_file.h: m_string.h moves up for LEX_STRING to be known in pagecache.h 2006-12-18 17:24:02 +01:00			`#include <m_string.h>`
