[McIDAS #MWQ-801749]: McIDAS-X 2009 and Solaris 11 Express



Hi Robert,

Sorry for the incredibly long delay on getting back to your problem on a MCGUI
race condition upon startup:

> I have confirmed that McIDAS-X 2009 build with either gcc or Sun Studio 
> results
> in a race condition with McGUI where the GUI keeps loading and nearly locks up
> the X-display.

Since you reported that the SSEC GUI does not exhibit the continual resizing 
that
"nearly locks up the X-display", I would like you to try the following change:

-- edit the copy of upcguiprocs.tcl that is installed in the ~mcidas/bin 
directory
   change the following code sequence in the 'reparentXwin' procedure (approx. 
line 
   14008)

   Change:

    # Wait until the window exists.  Total wait time is <= 30 seconds.
    set i 0
    while { $i < 30000 } {
        set windowid [ucPeek $ucloc]
        if $windowid {
            raise .
            update
            break
        }
        incr i
        after 100
    }


   To:

    # Wait until the window exists.  Total wait time is 30 seconds.
    set i 0
    while { $i < 30000 } {
        set windowid [ucPeek $ucloc]
        if $windowid {
            after 100
            raise .
            update idletasks
            break
        }
        incr i
        after 100
    }

Let's hold off on worrying about the SSEC GUI until we get the MCGUI startup 
working
correctly under your version of Solaris.

Comment:

- the continual resizing is most likely timing-related.  If the slight 
alteration
  I suggest above does not work, please make the following additional change in
  procedure 'reparentXwin':

  Change:

    # Reparent the McIDAS Xwindow
    xwindow $win $windowid
    grid configure $win -sticky "news"

  To:

    # Reparent the McIDAS Xwindow
    after 1000
    xwindow $win $windowid
    grid configure $win -sticky "news"

Comparing the startup logic in the SSEC GUI and my MCGUI shows that the
biggest difference is the SSEC GUI's waiting for 2 full seconds before trying
to reparent the 'mcimage' window by Tk.  My initial stab at the problem is
to wait for 0.1 seconds.  If that doesn't work for you, the next suggestion
is to wait for 1 second.
Cheers,

Tom
