- Implement heap free operation using already implemented busy/free/available/unused lists support and other base routines. - Implement missing place to free list and remove from busy list routines. - Implement find busy block routine (using AVL tree). - Fix a bug in RtlpDphCoalesceNodeIntoAvailable() which resulted in unwanted attempt to merge the only node with itself (which failed anyway). - Fix a bug in RtlpDphCoalesceNodeIntoAvailable() which incorrectly removed a node from available list (which is implemented as a standard NT double-linked list, compared to unused and free lists which are implemented as single-linked custom lists and busy list which is an AVL tree). Result of that bug was an infinite loop at the next attempt to traverse the list of available nodes. - In RtlpDphCoalesceFreeIntoAvailable() break when FreeAllocations becomes less than LeaveOnFreeList (before it would break 1 size too early). - Fix list traversal in RtlpDphSearchAvailableMemoryListForBestFit(). If it couldn't find a node, it would return the last node in the list instead of NULL. - In RtlpDphFindAvailableMemory(), a new smaller size should be 4 times smaller, not just 2. - Add a #if0-ed section in RtlpDphRemoveFromAvailableList which checks if a request to remove node not in the list performed. Used only for debugging. - Add a trace dprint to every type of list insert/removal operation for easier tracking. - Add break on NULL ptr freeing support. - RtlpDphSetProtectionAfterUse() is stubbed and protection is set directly in RtlpDphHeapFree(). To be moved into this function. svn path=/trunk/; revision=50860 |
