#include "H5SLprivate.h" /* Skip lists */
-/****************************************************************************
- *
- * We maintain doubly linked lists of instances of H5C_cache_entry_t for a
- * variety of reasons -- protected list, LRU list, and the clean and dirty
- * LRU lists at present. The following macros support linking and unlinking
- * of instances of H5C_cache_entry_t by both their regular and auxilary next
- * and previous pointers.
- *
- * The size and length fields are also maintained.
- *
- * Note that the relevant pair of prev and next pointers are presumed to be
- * NULL on entry in the insertion macros.
- *
- * Finally, observe that the sanity checking macros evaluate to the empty
- * string when H5C_DO_SANITY_CHECKS is FALSE. They also contain calls
- * to the HGOTO_ERROR macro, which may not be appropriate in all cases.
- * If so, we will need versions of the insertion and deletion macros which
- * do not reference the sanity checking macros.
- * JRM - 5/5/04
- *
- * Changes:
- *
- * - Removed the line:
- *
- * ( ( (Size) == (entry_ptr)->size ) && ( (len) != 1 ) ) ||
- *
- * from the H5C__DLL_PRE_REMOVE_SC macro. With the addition of the
- * epoch markers used in the age out based cache size reduction algorithm,
- * this invarient need not hold, as the epoch markers are of size 0.
- *
- * One could argue that I should have given the epoch markers a positive
- * size, but this would break the index_size = LRU_list_size + pl_size
- * + pel_size invarient.
- *
- * Alternatively, I could pass the current decr_mode in to the macro,
- * and just skip the check whenever epoch markers may be in use.
- *
- * However, any size errors should be caught when the cache is flushed
- * and destroyed. Until we are tracking such an error, this should be
- * good enough.
- * JRM - 12/9/04
- *
- *
- * - In the H5C__DLL_PRE_INSERT_SC macro, replaced the lines:
- *
- * ( ( (len) == 1 ) &&
- * ( ( (head_ptr) != (tail_ptr) ) || ( (Size) <= 0 ) ||
- * ( (head_ptr) == NULL ) || ( (head_ptr)->size != (Size) )
- * )
- * ) ||
- *
- * with:
- *
- * ( ( (len) == 1 ) &&
- * ( ( (head_ptr) != (tail_ptr) ) ||
- * ( (head_ptr) == NULL ) || ( (head_ptr)->size != (Size) )
- * )
- * ) ||
- *
- * Epoch markers have size 0, so we can now have a non-empty list with
- * zero size. Hence the "( (Size) <= 0 )" clause cause false failures
- * in the sanity check. Since "Size" is typically a size_t, it can't
- * take on negative values, and thus the revised clause "( (Size) < 0 )"
- * caused compiler warnings.
- * JRM - 12/22/04
- *
- * - In the H5C__DLL_SC macro, replaced the lines:
- *
- * ( ( (len) == 1 ) &&
- * ( ( (head_ptr) != (tail_ptr) ) || ( (cache_ptr)->size <= 0 ) ||
- * ( (head_ptr) == NULL ) || ( (head_ptr)->size != (Size) )
- * )
- * ) ||
- *
- * with
- *
- * ( ( (len) == 1 ) &&
- * ( ( (head_ptr) != (tail_ptr) ) ||
- * ( (head_ptr) == NULL ) || ( (head_ptr)->size != (Size) )
- * )
- * ) ||

- * take on negative values, and thus the revised clause "( (Size) < 0 )"
- * caused compiler warnings.
- * JRM - 1/10/05
- *
- * - Added the H5C__DLL_UPDATE_FOR_SIZE_CHANGE macro and the associated
- * sanity checking macros. These macro are used to update the size of
- * a DLL when one of its entries changes size.
- *
- * JRM - 9/8/05

- **************************************************************************/

- *
- * Macro: H5C__INSERT_ENTRY_IN_SLIST
- *
- * Purpose: Insert the specified instance of H5C_cache_entry_t into
- * the skip list in the specified instance of H5C_t. Update
- * the associated length and size fields.
- *
- * Return: N/A
- *
- * Programmer: John Mainzer, 5/10/04
- *
- * Modifications:
- *
- * JRM -- 7/21/04
- * Updated function to set the in_tree flag when inserting
- * an entry into the tree. Also modified the function to
- * update the tree size and len fields instead of the similar
- * index fields.
- *
- * All of this is part of the modifications to support the
- * hash table.
- *
- * JRM -- 7/27/04
- * Converted the function H5C_insert_entry_in_tree() into
- * the macro H5C__INSERT_ENTRY_IN_TREE in the hopes of
- * wringing a little more speed out of the cache.
- *
- * Note that we don't bother to check if the entry is already
- * in the tree -- if it is, H5SL_insert() will fail.
- *
- * QAK -- 11/27/04
- * Switched over to using skip list routines.
- *
- * JRM -- 6/27/06
- * Added fail_val parameter.
- *
- * JRM -- 8/25/06
- * Added the H5C_DO_SANITY_CHECKS version of the macro.
- *
- * This version maintains the slist_len_increase and
- * slist_size_increase fields that are used in sanity
- * checks in the flush routines.
- *
- * All this is needed as the fractal heap needs to be
- * able to dirty, resize and/or rename entries during the
- * flush.
