// does not specify stack size. Instead, it specifies the size of |
|
642 |
// initially committed space. The stack size is determined by |
|
643 |
// PE header in the executable. If the committed "stack_size" is larger |
|
644 |
// than default value in the PE header, the stack is rounded up to the |
|
645 |
// nearest multiple of 1MB. For example if the launcher has default |
|
646 |
// stack size of 320k, specifying any size less than 320k does not |
|
647 |
// affect the actual stack size at all, it only affects the initial |
|
648 |
// commitment. On the other hand, specifying 'stack_size' larger than |
|
649 |
// default value may cause significant increase in memory usage, because |
|
650 |
// not only the stack space will be rounded up to MB, but also the |
|
651 |
// entire space is committed upfront. |
|
652 |
// |
|
653 |
// Finally Windows XP added a new flag 'STACK_SIZE_PARAM_IS_A_RESERVATION' |
|
654 |
// for CreateThread() that can treat 'stack_size' as stack size. However we |
|
655 |
// are not supposed to call CreateThread() directly according to MSDN |
|
656 |
// document because JVM uses C runtime library. The good news is that the |
|
657 |
// flag appears to work with _beginthredex() as well. |

// An Event wraps a win32 "CreateEvent" kernel handle. |
5056 |
// |
|
5057 |
// We have a number of choices regarding "CreateEvent" win32 handle leakage: |
|
5058 |
// |
|
5059 |
// 1: When a thread dies return the Event to the EventFreeList, clear the ParkHandle |
|
5060 |
// field, and call CloseHandle() on the win32 event handle. Unpark() would |
|
5061 |
// need to be modified to tolerate finding a NULL (invalid) win32 event handle. |
|
5062 |
// In addition, an unpark() operation might fetch the handle field, but the |
|
5063 |
// event could recycle between the fetch and the SetEvent() operation. |
|
5064 |
// SetEvent() would either fail because the handle was invalid, or inadvertently work, |
|
5065 |
// as the win32 handle value had been recycled. In an ideal world calling SetEvent() |
|
5066 |
// on an stale but recycled handle would be harmless, but in practice this might |
|
5067 |
// confuse other non-Sun code, so it's not a viable approach. |
|
5068 |
// |
|
5069 |
// 2: Once a win32 event handle is associated with an Event, it remains associated |
|
5070 |
// with the Event. The event handle is never closed. This could be construed |
|
5071 |
// as handle leakage, but only up to the maximum # of threads that have been extant |
|
5072 |
// at any one time. This shouldn't be an issue, as windows platforms typically |
|
5073 |
// permit a process to have hundreds of thousands of open handles. |
|
5074 |
// |
|
5075 |
// 3: Same as (1), but periodically, at stop-the-world time, rundown the EventFreeList |
|
5076 |
// and release unused handles. |
|
5077 |
// |
|
5078 |
// 4: Add a CRITICAL_SECTION to the Event to protect LD+SetEvent from LD;ST(null);CloseHandle. |
|
5079 |
// It's not clear, however, that we wouldn't be trading one type of leak for another. |
|
5080 |
// |
|
5081 |
// 5. Use an RCU-like mechanism (Read-Copy Update). |
|
5082 |
// Or perhaps something similar to Maged Michael's "Hazard pointers". |
|
5083 |
// |
|
5084 |
// We use (2). |

// 1. Reconcile Doug's JSR166 j.u.c park-unpark with the objectmonitor implementation. |

// 2. Consider wrapping the WaitForSingleObject(Ex) calls in SEH try/finally blocks |
|
5089 |
// to recover from (or at least detect) the dreaded Windows 841176 bug. |
