--- Comment #5 from Jeremy White jwhite@codeweavers.com 2010-03-14 18:02:29 --- With Wine 1.1.40 and iTunes 9, this occurs consistently now.
One clue: the main thread (0009) seems normal until after a WM_TIMER fires. Once that happens, 0009 seems to go into a fairly tight spin loop, where it sees a WM_TIMER message and then posts a com.apple.webKit.TimerFired (c06f) message over and over again.
My hunch: the WM_TIMER message is not being dequeued properly somehow.

--- Comment #7 from Jeremy White jwhite@codeweavers.com 2010-03-14 18:35:32 --- I've attached a hack that makes the store operate.
It's puzzling; the behavior I see is something like this: PeekMessage (a 60cf is in queue) GetMessage Message Hooks Fire Message Hooks do a PeekMessage(...WM_TIMER, WM_TIMER...) which succeeds and triggers a PostMessage of a new 60cf GetMessage finishes
rinse, repeat. So it's as though if there is a WM_TIMER in queue when a 60cf is being processed, we get into this world of hurt.

--- Comment #8 from Jeremy White jwhite@codeweavers.com 2010-03-15 10:23:04 --- The issue seems to stem from the fact that our dsound implementation includes a winmm timer that sends a WM_TIMER every 10 ms. Further, iTunes lolligags a bit between posting it's TimerFired message and doing a GetMessage(), which pretty much guarantees that a WM_TIMER will be in queue behind the TimerFired message, which triggers the bug.

--- Comment #9 from Jeremy White jwhite@codeweavers.com 2010-03-15 15:04:19 --- My mistake; it's not winmm or dsound. Something else is setting a timer that fires every 83 ms; that's the timer that's triggering.

--- Comment #10 from Jeremy White jwhite@codeweavers.com 2010-03-16 15:50:56 --- Maarten points out that if you look at r53273 of this file in WebKit: WebCore/platform/win/SharedTimerWin.cpp you can find a fairly clear map to a portion of the code. At the very least, you can find a clear path that explains some code around the Webkit...TimerFired message.
However, a lengthy analysis of that code doesn't reveal the problem (at least not to my admittedly flawed eyes).
It still seems as though there is some iTunes specific code in a set of Windows Hooks, and it is that code that is the culprit.
However, you have to make some fairly improbably assumptions about that code to make that make sense. The idea that the Windows hooks repost a given message if there is a WM_TIMER in the queue is pretty dicey, for starters (that should fail on Windows).
My ending hunch is that there is something going on with code paths based on timing information; that iTunes decides it has a particular sort of timers and that causes it to behave in a way it doesn't on Windows.
(And Maarten found that if he mucked with GetQueueStatus, he could also get a successful result; so that timing change also seems to help. See the SharedTimerWin.cpp code to speculate as to why that might be).

--- Comment #11 from Matt Hargett matt@use.net 2010-06-07 14:54:58 --- I'm still seeing this problem with wine-1.2-rc2. Let me know if there's any logs you'd like me to supply, or things you'd like me to test to help bring this to resolution before (or soon after) 1.2 releases.
Thanks!
