Re: [platform-swt-dev] UI freezes after upgrading to 3.5.x
|
Hi Silenio,
Thanks for the tip, I'll try rolling
my own SWT 3.5 and see where that takes me.

It is hard to guess without a testcase. The only change between 3.4.x and
3.5.x in the wake/ayncExec area that comes to mind is a change in org.eclipse.swt.widgets.Display.foregroundIdleProc()
to fix this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=256469
You could get SWT from CVS and hack the code. Either start with 3.4.x and
add the change (see if the problem starts happening) or start with 3.5.x
and remove the change (see if the problem goes away).
Please open a bug report if you find a simple testcase that reproduces
the problem.
3.5.x code
int /*long*/
foregroundIdleProc (int
/*long*/
code, int
/*long*/
wParam, int
/*long*/
lParam) {
if
(code >= 0) {
if
(runMessages && getMessageCount () != 0) {
if
(runMessagesInIdle) {
if
(runMessagesInMessageProc) {
OS.PostMessage
(hwndMessage, SWT_RUNASYNC, 0, 0);
} else
{
runAsyncMessages
(false);
}
}
MSG msg = new
MSG();
int
flags = OS.PM_NOREMOVE | OS.PM_NOYIELD | OS.PM_QS_INPUT | OS.PM_QS_POSTMESSAGE;
if
(!OS.PeekMessage (msg, 0, 0, 0, flags)) wakeThread ();
}
}
return
OS.CallNextHookEx (idleHook, (int)/*64*/code,
wParam, lParam);
}
3.4.x code
int /*long*/
foregroundIdleProc (int
/*long*/
code, int
/*long*/
wParam, int
/*long*/
lParam) {
if
(code >= 0) {
if
(runMessages && getMessageCount () != 0) {
if
(runMessagesInIdle) {
if
(runMessagesInMessageProc) {
OS.PostMessage
(hwndMessage, SWT_RUNASYNC, 0, 0);
} else
{
runAsyncMessages
(false);
}
}
wakeThread ();
}
}
return
OS.CallNextHookEx (idleHook, (int)/*64*/code,
wParam, lParam);
}

Hi,
We have a thread-happy UI that functions nicely in 3.4.x.
Since upgrading, after about 10 seconds of running the UI will freeze,
and only update when the mouse cursor is moved over the window (or triggering
any other Windows WM_ message). Breaking into the main (UI) thread shows
it stuck inside OS.WaitMessage(). The rest of the application has carried
along regardless, except for Display.syncExec calls which are blocked.
Display.asyncExec calls seemed to get queued and processed when the app
wakens.
This only happens on Win32 (x86 and x64) and not on Mac OS X or Linux,
which function fine.
Does this sound familiar?
I'm trying to build a test case/narrow down the problem, but it's elusive.
(Apologies if this isn't the right newsgroup for this message, feel free
to punt me onto another).
