Minor progress on Windows clipboard deadlock

Minor progress on Windows clipboard deadlock

[Øyvind Harboe]

I believe I've made a tiny step towards finding out when this happens.


Before the deadlock happens copying from windows and pasting in e.g.
Evolution no longer works.

I.e. the paste behaves as if the clipboard is empty.

At this point XWin is doomed.

If you subsequently copy from e.g. Evolution and paste in any Windows
app, that Windows app is deadlocked.

Øyvind,

I think I fixed at least part of your problem with the clipboard support 
when compiling from CVS.  It turned out that my OsVendorReset function 
was not being called in the CVS version because -DDDXOSRESET was not 
being defined where the files in Xserver/dix/ could see it, thus no call 
was made to OsVendorReset since it is wrapped with #ifdef DDXOSRESET.

I'm not sure if you were using Xdmcp or if you were using -mutliwindow 
with ssh.  If you were using Xdmcp, then this may fix your problem; if 
you are only using ssh, then it is unlikely to help.

The deadlock occurs for me on one monitor.  One thing I notice just
before it usually happens is that I usually select something in an
xterm but before I paste that first crash into a Windows app, that
xterm will get more input and the selection disappears, as usually
happens.  Might that have something to do with it?  Sorry I can't
contribute more at the moment but I'm really busy with work.

BTW running Win2K and xserv 44.

I occasionally have the windows app hang when pasting from X to Windows and
I use XP with a single monitor.

Yes, I am using XP and two monitors, and I was pasting from the X
server displayed on one monitor to an app displayed in the other.  I
think.

I have not tested that the deadlock does not occur when not using two
monitors.

-multiwindow + ssh.

I'm still on the lookout for when this happens, but I haven't run with -48 
for very long.

I would say that there is inconclusive evidence that this this deadlock does not
occur under W2K with a single monitor, but only on a XP machine w/multiple monitors.
