Hi Harold
You made my day !!!! The selection ownership problem really went away.
I'm running the X version of XEmacs since half a day now and no
problems with selection and copy/paste between X and Windows.

[Andrew Braverman]

I just tried running this version and it crashes.  I get a normal looking
stuff at the beginning of the XWin.log file and then get one line telling
me:
	winClipboardWindowProc - WM_DRAWCLIPBOARD - Initializing - Returning.
Then I get 64K + lines (total size of log file is 65072 lines) of:
	winProcSetSelectionOwner - We changed ownership, aborting.

Does anyone have any ideas?

A couple of hours later it stopped working, now my XWin.log fills up
with

 winProcSetSelectionOwner - OpenClipboard () failed: 00000578
 winProcSetSelectionOwner - OpenClipboard () failed: 00000578

Great!  I was sort of afraid to test it really hard... I didn't want to 
find out for myself that it had major bugs.  :)  That is great to hear 
that it is holding up.

Re: Updated: XFree86-xserv-4.3.0-31

[Harold L Hunt II]

Andrew,

Yup, this happens when you are using -query and there are no entries in 
your .Xauthority file.  You can alleviate this by running it again after 
it crashes, since the previous entries are left in the file.  This is 
something that still has to be fixed or worked around and that is why 
these are 'test' releases.  Sorry for not describing this particular 
failure mode in the announcement.

Hmm... that is not something I had seen before.  Did an earlier entry in 
the XWin.log say anything about the clipboard manager shutting down? 
Want to bzip2 it and send XWin.log to me privately?

Hmm... I guess I didn't tell you guys that server resets were not 
supported, right?  :)

I already had a fix in my code base for this last night.  The problem is 
that the server functions vectors are only setup once, but I keep 
wrapping the function each time the server resets.  I added an if 
(serverGeneration == 1) to my local code last night, just after I posted 
the 4.3.0-31 release.  That should stop the multiple wrapping from 
happening, which is causing the crash.

RE: Updated: XFree86-xserv-4.3.0-31

[Andrew Braverman]

No problem.  I understood it was a test release and just went back to the
old.

FYI -

I am not, however, using the -query parameter in my XWin invocation.  I am
using ssh tunnels and therefore am not doing a query.  The invocation looks
like this:





XWin -once -emulate3buttons -clipboard -multiwindow -lesspointer -clipupdate
s 5 &

Even running it multiple times gets me the same result.  I will check it
again the next time you put it out.  I would love to use it.  It sounds like
it will solve a bunch of problems.

As usual, sincere thanks go out to the crew of a half dozen or so of you who
do most of the work on this project.  If it were not for you guys
(especially Harold), this project would not go anywhere.  There are many
other contributors who deserve thanks, but they would not have something to
contribute to without the core group of you guys.  One of these days, when I
have some "free" time, I need to try to look more deeply at the code and try
to help out some more.  Thanks again to all for a wonderful product.

Here is a dumb question: if the clipboard client is attached, how did 
you cause a server reset?  Is there a way to force the server to reset 
when there are clients still attached?  I need to be able to do this in 
order to test my fix... and it sounds like there is a way to do this, 
since I don't think it could happen automatically.

how about
if (ProcVector[X_SetSelectionOwner] != winSetSelectionOwner)
{
    oldSetSelectionOwner = ProcVector[X_SetSelectionOwner];
    ProcVector[X_SetSelectionOwner] = winSetSelectionOwner;
}

Sorry, I'm reading this mail from my home. So I already booted my
laptop and XWin.log got overwritten. If I see the error again I'll send it to you.....

good question. I've started a session and stopped the windowmanager. The
log showed signs of another server generation. I'll check tomorrow.

Maybe the clipboard client died before.

I've also noticed different behaviour (crash or segfault) depending on
which side (X11, Win32) has changed the clipboard last but had no time
to examine this further. I can test it tomorrow.

I'm quite sure there are similar functions to TerminateServer.

Yeah, it had been a couple of months.... I usually try to avoid upgrading it unless there is a new feature I want (if its not broke....)

I had to track down three missing dll files, but now the cut and paste upgrades are working great.

Thanks for your work yet again, Harold.

This was about the only thing on my "it would be nice if it was fixed" list.... For my uses of cygwin anyway.

You must have been going for a very long time before upgrading.  Yes, 
the cygipc package is a dependency of the X packages, but if you upgrade 
from an old version that did not require it, then it might not be 
automatically selected for installation.  The solution is to manually 
select the cygipc package.

I just upgraded my install, and now it reports a missing dll file (cygcygipc-2.dll).  Should the installer handle this automatically?
