XWin causes Windows apps to hang(?)

XWin causes Windows apps to hang(?)

[Øyvind Harboe]

[-- Attachment #1: Type: text/plain, Size: 286 bytes --]

This was with -42.

- I copied a URL from an email message in Evolution
- When I paste into a Windows app, that Windows app is stuck. This
happened w/iexplorer and explorer.exe.

It appears as if the Windows app is stuck indefinitely waiting for the
"pastable" from XWin.

I am seeing this too.  I tried pasting into several different
applications, in all cases it caused the app to hang and I had to kill
it using the task manager.  Cut and paste between normal Windows apps,
or pasting from Windows to XWin, is fine.

XWin.exe --version did not produce any output, however the Cygwin
setup program shows I am running XFree86-xserv-4.3.0-44 and
XFree86-xwinclip-4.3.0-2.  I had manually started xwinclip.exe after
the built-in clipboard support seemingly crashed.

It looks as though by running XWin.exe --version I overwrote the log
file, but when this problem happens again I will provide a log.  (It
might be that next time will also be with a separate xwinclip.exe
after the builtin clipboard support crashed.)

Here is the XWin.log for an X session that does this.  The server is
running happily but it will crash any Windows app I try to paste into
from the X selection.  I wonder if it might be the line

winProcSetSelectionOwner - OpenClipboard () failed: 00000000

The log follows.

Re: XWin causes Windows apps to hang(?)

[Harold L Hunt II]

Ed,

Yes, the OpenClipboard failure is probably causing your crash.  Try 
editing your startxwin.bat and removing the -clipboard parameter being 
passed to XWin.exe.  There is likely a bug in XWin.exe's clipboard 
support that will need to be fixed.

If I do that then I can run a separate xwinclip.exe.  If xwinclip gets
into a wedged state then it can be killed and restarted.

Let me know if you would like me to do something to help reproduce or

winProcSetSelectionOwner - OpenClipboard () failed: 00000000

0 is ERROR_SUCCESS which means "The operation completed successfully"
I guess the clipboard was opened successfully but returned a wrong
error condition. After bailing out we leave the clipboard in an open
state and other programs can not access it anymore.

I guess this is worth a try:

from winclipboardwrappers.c:461

  /* Access the Windows clipboard */
  if (!OpenClipboard (g_hwndClipboard))
    {
      DWORD errorcode = GetLastError();
      ErrorF ("winProcSetSelectionOwner - OpenClipboard () failed: %08x\n",
            (int) errorcode);
      if (errorcode != ERROR_SUCCESS)
        goto winProcSetSelectionOwner_Done;
    }

This was a deadend too. The call to EmptyClipboard now returned an error
stating the clipboard was not open.

This was a deadend too. I had XWin running with this change and it
produced logmessages (from memory):

OpenClipboard () failed: 0000000
EmptyClipboard () failed: $NUMBER (Clipboard not open error)
