16 /* -

17 ** A complete page cache is an instance of this structure. Every -

18 ** entry in the cache holds a single page of the database file. The -

19 ** btree layer only operates on the cached copy of the database pages. -

20 ** -

21 ** A page cache entry is "clean" if it exactly matches what is currently -

22 ** on disk. A page is "dirty" if it has been modified and needs to be -

23 ** persisted to disk. -

24 ** -

25 ** pDirty, pDirtyTail, pSynced: -

26 ** All dirty pages are linked into the doubly linked list using -

27 ** PgHdr.pDirtyNext and pDirtyPrev. The list is maintained in LRU order -

28 ** such that p was added to the list more recently than p->pDirtyNext. -

29 ** PCache.pDirty points to the first (newest) element in the list and -

30 ** pDirtyTail to the last (oldest). -

31 ** -

32 ** The PCache.pSynced variable is used to optimize searching for a dirty -

33 ** page to eject from the cache mid-transaction. It is better to eject -

34 ** a page that does not require a journal sync than one that does. -

35 ** Therefore, pSynced is maintained so that it *almost* always points -

36 ** to either the oldest page in the pDirty/pDirtyTail list that has a -

37 ** clear PGHDR_NEED_SYNC flag or to a page that is older than this one -

38 ** (so that the right page to eject can be found by following pDirtyPrev -

39 ** pointers). -
