// An Event wraps a win32 "CreateEvent" kernel handle. |
|
4480 |
// |
|
4481 |
// We have a number of choices regarding "CreateEvent" win32 handle leakage: |
|
4482 |
// |
|
4483 |
// 1: When a thread dies return the Event to the EventFreeList, clear the ParkHandle |
|
4484 |
// field, and call CloseHandle() on the win32 event handle. Unpark() would |
|
4485 |
// need to be modified to tolerate finding a NULL (invalid) win32 event handle. |
|
4486 |
// In addition, an unpark() operation might fetch the handle field, but the |
|
4487 |
// event could recycle between the fetch and the SetEvent() operation. |
|
4488 |
// SetEvent() would either fail because the handle was invalid, or inadvertently work, |
|
4489 |
// as the win32 handle value had been recycled. In an ideal world calling SetEvent() |
|
4490 |
// on an stale but recycled handle would be harmless, but in practice this might |
|
4491 |
// confuse other non-Sun code, so it's not a viable approach. |
|
4492 |
// |
|
4493 |
// 2: Once a win32 event handle is associated with an Event, it remains associated |
|
4494 |
// with the Event. The event handle is never closed. This could be construed |
|
4495 |
// as handle leakage, but only up to the maximum # of threads that have been extant |
|
4496 |
// at any one time. This shouldn't be an issue, as windows platforms typically |
|
4497 |
// permit a process to have hundreds of thousands of open handles. |
|
4498 |
// |
|
4499 |
// 3: Same as (1), but periodically, at stop-the-world time, rundown the EventFreeList |
|
4500 |
// and release unused handles. |
|
4501 |
// |
|
4502 |
// 4: Add a CRITICAL_SECTION to the Event to protect LD+SetEvent from LD;ST(null);CloseHandle. |
|
4503 |
// It's not clear, however, that we wouldn't be trading one type of leak for another. |
|
4504 |
// |
|
4505 |
// 5. Use an RCU-like mechanism (Read-Copy Update). |
|
4506 |
// Or perhaps something similar to Maged Michael's "Hazard pointers". |
|

// |
