Hi all,

I use X11R5 on a SPARC, and I would like to get a recent version of the server.
In particular, one with the NumLock patch applied. I can't build it myself
right now, because I have insufficient hard disk space, hence the question.
Is there a location where I could ftp it anonymously? Or would someone be
willing to mail me a floppy?
Thanks in advance!

Subject: Major memory leak in asciiTextWidget (X11R4)
Organization: Sterling Software @NASA-Ames Research Center
Date: Tue, 15 Sep 92 23:36:37 GMT

We have a very large and complex program that was initially
developed under X11R3 and then extensively modified under
early X11R4.  We are now trying again to add some upgrades, and
extend the program so it will run under both X11R4 & X11R5. Unfortunately,
some of the changes we put in for X11R5 leak like hell when run
under X11R4.
 
One of the changes made was to replace all of the asciiStringWidgetClass
args to XtCreateWidget with asciiTextWidgetClass, and then modify the
associated args and code accordingly.

A copy of a purify report follows. I'm hoping that
someone out there will recognize the symptoms because the program
is much too big to post.
 
The question(s)that I have for you xperts is this:

1. is AsciiTextWidgetClass a lost cause in this regard? or-
2. Are we missing patches to X11R4 that addressed this problem
   ( we had to blow away the X11R4 sources long ago because
   of disk space problems. )    - or
3. Am I in error in using XtSetValues to change the text in the 
   viewable portion of an AsciiText Widget?

be specified in the XtAddEventHandler call, becuase of the C language structure.
Then my question is, how are argument passed to the event handler ?
Is it necessary that in the event handler definition the formal paremeters be
widget, clientData, and event, (in this precise order) ?.

I think WRS is right.  It is not present in our (pre-Tahoe) 4.3.  It is
part of the POSIX session junk.

> Q: does anybody have the source code for setsid ?
> Q: is it available at ftp.uu.net:/systems/unix/bsd-sources/lib

Maybe.  BSD may have gone far enough towards POSIX compatability to
provide it.  In BSD terms, it is something like using TIOCNOTTY on a
file descriptor to /dev/tty and calling setpgrp(0,getpid()), but is
more complicated because POSIX gratuitously (and unnecesarily)
introduced a new concept, that of a session, that BSD doesn't have.

For porting to BSD, though, you can probably get away with something
like this:

#include <sys/file.h>
#include <sys/ioctl.h>

setsid()
{
 int i;

 i = open("/dev/tty",O_RDWR,0);
 if (i >= 0)
  { ioctl(i,TIOCNOTTY,0);
    close(i);
  }
 setpgrp(0,getpid());
}

This really has little or nothing to do with X; it's a UNIX-derivative
incompatibility issue.  As such, I'm crossposting to, and pointing
followups to, comp.unix.programmer.

Now I'm confused.  What's a "R4 server", and how would it differ
from, say, a "R3 server" or "R5 server" ?  I've recently spent
many decahours with manuals and dirty experiments achieving the
enlightened understanding that my server speaks only the X Protocol,
Major version = 11, Minor version = 0 (plus the shape extension and
XDMCP) and that all this R# icing is layered above that on the client
side library only.

(Not only that, /* name drop */ Oliver Jones told me that the
 lower levels of X were very stable and not to worry about R4->R5.)

What am I missing ?

(X11R3, I think).  I will need the X11 include files as a start.  I have
looked through my /usr/openwin/include/X11 directory and have not found
anything yet.  If I had used the VAX MIT/C bindings on the VMS side,
would I fare any better?  I am not familiar with any other examples of
Xwindow calls from FORTRAN outside of the VAX examples I have.

        Besides a suggestion to re-write completly in C, does anyone

I've seen this answered in pieces; this is an attempt to pull it all
together and make sense of it.

First: it's a bug in the xterm app-defaults file.  App-defaults files
should *always* be as loose as possible - no application name/class,
all classes instead of instance names whenever possible, * instead of .
whenever possible, etc.  Your sort of problem is why.

Ideally, you should go into the app-defaults file and remove the
"XTerm" that's causing the problem.  If you can't do that, you need to
add a leading "xterm" or "XTerm" to your resource line.  (Either one
should work, since the rest of your resource uses names instead of the
classes the app-defaults file uses, so yours will be preferred.)  You
may be able to make your own copy of the annoying app-defaults file and
play games with environment variables to make the lookup at run-time
find your copy; I don't know....

I would like to obtain source code for a version of "olvwm" (OpenLook Virtual

former system administrator of ours obtained a version of "olvwm" several
months ago, but he has since left the company and we've lost the source code.

The version we currently have works fine for OpenLook 2.0 libraries, but we
are upgrading to Xnews/OpenWindows 3.0.  With OpenWindows 3.0, we don't get
all of the correct window "decorations" such as resize corners, title bars,
etc.

I really liked using "olvwm" since I could have a separate root window for
each current "hot topic" I was working on.  I would consider another virtual
window manager if there is a public domain version available.

Any assistance would be appreciated.

You might try two things:
(1) draw the small arc into a pixmap, and use XCopyPlane
    to XOR it into your window.
(2) make up a font containing the "frames" of your animation
    as individual characters.  Then use XDrawText to output them.

2 is a lot of programming and font-hacking work, but it will

I'm afraid you are wrong about that.  For typing, right-handed people can
type as fast or faster with their left hand than their right.  An experiment
has be performed that tested this.  I can't remember the reference off the
top of my head, but I can look it up if anyone is interested.

It makes a lot more sense to use your dominant hand for the mouse and
your non-dominant hand for typing.  Right-handed people should use their
right hand for the mouse.

Thanx for any replies!
