// Page Heap Global Flags
|
|
//
|
|
// These flags are kept in a global variable that can be set from
|
|
// debugger. During heap creation these flags are stored in a per heap
|
|
// structure and control the behavior of that particular heap.
|
|
//
|
|
// PAGE_HEAP_ENABLE_PAGE_HEAP
|
|
//
|
|
// This flag is set by default. It means that page heap allocations
|
|
// should be used always. The flag is useful if we want to use page
|
|
// heap only for certain heaps and stick with normal heaps for the
|
|
// others. It can be changed on the fly (after heap creation) to direct
|
|
// allocations in one heap or another.
|
|
//
|
|
// PAGE_HEAP_CATCH_BACKWARD_OVERRUNS
|
|
//
|
|
// Places the N/A page at the beginning of the block.
|
|
//
|
|
// PAGE_HEAP_UNALIGNED_ALLOCATIONS
|
|
//
|
|
// For historical reasons (related to RPC) by default page heap
|
|
// aligns allocations at 8 byte boundaries. With this flag set
|
|
// this does not happen and we can catch instantly off by one
|
|
// errors for unaligned allocations.
|
|
//
|
|
// PAGE_HEAP_SMART_MEMORY_USAGE
|
|
//
|
|
// This flag reduces the committed memory consumption in half
|
|
// by using decommitted ranges (reserved virtual space) instead
|
|
// of N/A committed pages. This flag is disabled by catch backward
|
|
// overruns.
|
|
//
|
|
// PAGE_HEAP_USE_SIZE_RANGE
|
|
//
|
|
// Use page heap for allocations in the size range specified by:
|
|
// RtlpDphSizeRangeStart..RtlpDphSizeRangeEnd.
|
|
//
|
|
// PAGE_HEAP_USE_DLL_RANGE
|
|
//
|
|
// Use page heap for allocations in the address range specified by:
|
|
// RtlpDphDllRangeStart..RtlpDphDllRangeEnd. If the stack trace
|
|
// of the allocation contains one address in this range then
|
|
// allocation will be made from page heap.
|
|
//
|
|
// PAGE_HEAP_USE_RANDOM_DECISION
|
|
//
|
|
// Use page heap if we randomly decide so.
|
|
//
|
|
// PAGE_HEAP_USE_DLL_NAMES
|
|
//
|
|
// Use page heap if allocation call was generated from on of the
|
|
// target dlls.
|
|
//
|
|
// PAGE_HEAP_USE_FAULT_INJECTION
|
|
//
|
|
// Fault inject heap allocation calls based on a simple
|
|
// probabilistic model (see FaultProbability and FaultTimeOut).
|
|
//
|
|
// PAGE_HEAP_PROTECT_META_DATA
|
|
//
|
|
// Keep page heap metadata read only if we are not executing inside
|
|
// the page heap code.
|
|
//
|
|
// PAGE_CHECK_NO_SERIALIZE_ACCESS
|
|
//
|
|
// Additional checks for multi-threaded access for no_serialize
|
|
// heaps. This flag can trigger false positives in MPheap. It needs
|
|
// to be used only on processes that do not use MPheap-like heaps.
|
|
//
|
|
// PAGE_HEAP_USE_READONLY
|
|
//
|
|
// The page following (or preceding) the user allocation is marked
|
|
// RO instead of NA. This is useful when testing RPC servers which
|
|
// by design during unmarshalling might go off by a few bytes when
|
|
// probing parameters. This is so for performance reasons.
