* src/osgViewer, src/osgViewer/GraphicsWindowWin32.cpp: From Cory
|
||||
Riddell based on suggestion from Robert Osfield, "I've been
|
||||
running with your suggested changes for a few days now and it
|
||||
has been working perfectly. I'm still not entirely clear why
|
||||
adding a
|
||||
slave/subgraph causes the problem."

* src/OpenThreads/win32,
|
||||
src/OpenThreads/win32/Win32ConditionPrivateData.h: From David
|
||||
Fries, "Here is a fix for a deadlock seen under Windows using
|
||||
OpenThreads
|
||||
Barrier operations. The error is with atomic operations in the
|
||||
win32 condition implementation. The attached sample program will
|
||||
reliably trigger with as few as three threads and a dual core
|
||||
system,
|
||||
though sometimes it will take 65,000 iterations.
|
||||
|
||||
2.8.1 was the base for these changes
|
||||
|
||||
Win32ConditionPrivateData.h
|
||||
Win32ConditionPrivateData::wait does two operations to decrement
|
||||
waiters_ then read, when InterlockedDecrement decrements and
|
||||
returns
|
||||
the value in one operation. The two operations allows another
|
||||
thread
|
||||
to also decrement with both getting 0 for an answer.
|
||||
|
||||
Win32ConditionPrivateData::broadcast is using waiters_ directly
|
||||
instead of using the w value read earlier, if it was safe to use
|
||||
waiters_ directly there would be no need for InterlockedGet or w.
|
||||
|
||||
overview of deadlock in barrier with three threads
|
||||
one thread in broadcast, 2 threads in wait,
|
||||
release semaphore 2, waits on waiters_done_
|
||||
both threads wake, decrement waiters_, get 0 for w,
|
||||
<logic error here>
|
||||
one calls set waiters_done_,
|
||||
broadcast thread comes out of waiters_done_,
|
||||
other thread calls waiters_done_, (which leaves waiters_done_ in
|
||||
the
|
||||
signaled state)
|
||||
<sets the trap>
|
||||
broadcast thread returns releases mutex, other threads get
|
||||
mutex and also return,
|
||||
next barrier, first two threads enter wait, one goes to
|
||||
broadcast, release
|
||||
semaphore 2, skips waiters_done_ as it had been released last
|
||||
time
|
||||
returns, processes, enters the barrier for the next barrier
|
||||
operation
|
||||
and waits,
|
||||
three threads are now in wait, two have the previous barrier
|
||||
phase,
|
||||
one the current phase, there's one count left in the semaphore
|
||||
which a
|
||||
thread gets, returns, enters the barrier as a waiter, sleeps, and
|
||||
the
|
||||
deadlock is completed"

||||
