Drop DMX DDX 

It turns out xdmx currently crashes when any client attempts to use GL
and it has been in such state for about 14 years. There was a patch to
fix the problem [1] 4 years ago, but it never got merged. The last
activity on any bugs referring to xdmx has been more than 4 years ago.

Given such situation, I find it unlikely that anyone is still using xdmx
and just having the code is a drain of resources.

.SH NAME
vdltodmx - dmx configuration file parser and printer
.SH SYNOPSIS
.B vdltodmx
.I infile
.I outfile
.SH DESCRIPTION
.I vdltodmx
reads the input file, which should be in VDL configuration file format.
After a successful parse, a file in Xdmx configuration file format is
written to the output file.
.P
The VDL file format is used with
.IR xmovie ,
which is available from
http://www.llnl.gov/icc/lc/img/xmovie/xmovie.html
.SH EXAMPLE
Given the following VDL-format file:
.RS
.nf

.SH BUGS
If the VDL file is not in the expected format, the program will probably
dump core.

xdmxconfig - a graphical configuration tool for Xdmx configuration files
.SH SYNOPSIS
.B xdmxconfig
[filename]
.SH DESCRIPTION
.I xdmxconfig
reads, edits, and writes configuration files for the Xdmx server. The
grammar for the configuration file is specified in the Xdmx(1) manual
page.
.PP
To start from scratch, create a "New Global" and specify the name and
overall dimensions for the configuration. Then use "New Display" to
enter more displays.
.PP
If there is more than one configuration, the configuration name button
will bring up a selection menu.
.PP
In the right-hand panel, the left mouse button will move the
highlighted display at "tool resolution"; the middle mouse button will
move the highlighted display by a single pixel (at "wall resolution");
and the right mouse button will bring up a menu allowing the highlighted
display to be edited or deleted. The arrow keys will also move the
highlighted display by a single pixel.
.SH BUGS
Currently, entries with the
.B wall
keyword are not editable, but will be preserved in the new output file.
The tool will quit when requested by the user, even if a configuration
file has not been written out (i.e., without warning). The menu
interaction should be improved (menu entries that don't currently work
should be greyed-out, for example). The Help button does not work.
.SH "SEE ALSO"
Xdmx(1), vdltodmx(1)

/* The code below is non-obvious, so here's an explanation...
*
* When creating the default GC, the server opens up the
* default font once for each screen, which in turn calls
* the RealizeFont function pointer once for each screen.
* During this process both dix's font refcnt and DMX's font
* refcnt are incremented once for each screen.
*
* Later, when shutting down the X server, dix shuts down
* each screen in reverse order. During this shutdown
* procedure, each screen's default GC is freed and then
* that screen is closed by calling the CloseScreen function
* pointer. screenInfo.numScreens is then decremented after
* closing each screen. This procedure means that the dix's
* font refcnt for the font used by the default GC's is
* decremented once for each screen # greater than 0.
* However, since dix's refcnt for the default font is not
* yet 0 for each screen greater than 0, no call to the
* UnrealizeFont function pointer is made for those screens.
* Then, when screen 0 is being closed, dix's font refcnt
* for the default GC's font is finally 0 and the font is
* unrealized. However, since screenInfo.numScreens has
* been decremented already down to 1, only one call to
* UnrealizeFont is made (for screen 0). Thus, even though
* RealizeFont was called once for each screen,
* UnrealizeFont is only called for screen 0.
*
* This is a bug in dix.
*
* To avoid the memory leak of pFontPriv for each server
* generation, we can also free pFontPriv if the refcnt is
* not yet 0 but the # of screens is 1 -- i.e., the case
* described in the dix bug above. This is only a temporary
* workaround until the bug in dix is solved.
*
* The other problem is that the font structure allocated by
* XLoadQueryFont() above is not freed for screens > 0.
* This problem cannot be worked around here since the back-
* end displays for screens > 0 have already been closed by
* the time this code is called from dix.
*
* When the bug in dix described above is fixed, then we can
* remove the "|| screenInfo.numScreens == 1" code below and
* the memory leaks will be eliminated.
*/

1. Overview
The client-to-server DMX extension to the X protocol (DMX) provides
normal client applications with the ability to determine information
about the characteristics of the Xdmx server and the back-end X
servers that DMX is using.
The name for this extension is "DMX".
2. Syntactic conventions
This document uses the same syntactic conventions requests and data
types as [X11R6.4].
3. Data types
No new data types are defined by this extension. All data types
referenced in this document are defined in [X11R6.4].
4. Requests
DMXQueryVersion
==>
majorVersion: CARD32
minorVersion: CARD32
patchVersion: CARD32
The protocol this extension actually supports is indicated by
majorVersion and minorVersion (patchVersion indicates the
patchlevel and is for informational purposes only).
Any incompatible changes to the protocol should be indicated by
incrementing majorVersion.
Small, upward-compatible changes should be indicated by incrementing
minorVersion.
Servers that support the protocol defined in this document will
return a majorVersion of 1 and a minorVersion of 1.
DMXGetScreenCount
==>
screenCount: CARD32
This request returns the number of back-end screens that the Xdmx
server controls. A back-end screen may be managed as a regular X
screen in the Xdmx server or may be joined with other back-end
screens using Xinerama. (The information returned by this request
does not change while Xdmx is running and may be cached on the
client side.)
DMXGetScreenInformation
physicalScreen: CARD32
==>
displayName: STRING8
width: CARD16
height: CARD16
xoffset: INT16
yoffset: INT16
logicalScreen: CARD32
xorigin: INT16
yorigin: INT16
Errors: Value
This request returns information about individual back-end screens.
The physicalScreen value is between 0 and screenCount-1, inclusive
(values outside this range will result in a Value error). The
displayname is the name used to open the display, either from the
Xdmx command-line or from the configuration file. The width,
height, xoffset, and yoffset values comprise a geometry
specification (see X(7x)) for the location of the DMX window on the
back-end screen. This request will always return non-negative
(i.e., normalized) values for xoffset and yoffset. The
logicalScreen value is the value of the screen that that Xdmx server
exports to clients. When Xinerama is in use, this value is
typically 0 for all values of physicalScreen. If Xinerama is in
use, the xorigin and yorigin values specify where the physical
screen is positioned in the global Xinerama coordinate system.
Otherwise, these values are set to 0. (The information returned by
this request does not change while Xdmx is running and may be cached
on the client side.)
DMXGetWindowInformation
window: CARD32
==>
screenCount: CARD32
screens: LISTofCARD32
windows: LISTofCARD32
pos: LISTofRECTANGLE
vis: LISTofRECTANGLE
Errors: Window, Alloc
This request computed the return values incorrectly for version 1.0
of this protocol. Version 1.1 of this protocol conforms to this
description.
Given a window ID on the Xdmx server, this request returns data
about how the window is represented on the back-end X servers. For
each back-end X server that displays a portion of the window, the
following information is returned:
1) the number of the physical screen containing that portion
(which can be used with the DMXGetScreenInformation request
to obtain more information about the screen),
2) the window ID on the back-end X server of the window
containing that portion,
3) the position and dimensions of the window on the back-end, in
screen coordinates, and
4) the visible area of the window on the back-end, in
window-relative coordinates (all zeros for windows that are
not visible)
Note that DMX allows multiple back-end windows to overlap in their
view of the DMX logical window. Further, a logical window does not
have to be completely covered by back-end windows -- there may be
gaps.
As an example, consider a 500x500 window that spans the top two
1024x768 back-end displays (A and B) of a 2048x1536 DMX display
composed of 4 1024x768 back-end displays arranged in a cube:
A B
C D
In this case, the DMXGetWindowInformation call would return the
following information for the 500x500 window:
display A: 500x500 window at 1024-250,0 (relative to back end)
with 250x500 visible at 0,0 (relative to window origin)
display B: 500x500 window at -250,0 (relative to back end)
with 250x500 visible at 250,0 (relative to window origin)
display C: 500x500 window at 1024-250,-768 with 0x0 visible at 0,0
display D: 500x500 window at -250,-768 with 0x0 visible at 0,0
Note that if the specified window has not yet been mapped when
DMXGetWindowInformation is called, then a subsequent XMapWindow call
might be buffered in xlib while requests directly to the back-end X
servers are processed. This race condition can be solved by calling
DMXSync before talking directly to the back-end X servers.
DMXGetInputCount
==>
inputCount: CARD32
This request was first supported in version 1.1 of this protocol.
This request returns the number of input devices connected to the
Xdmx server. This number is the same as that returned by
XListInputDevices, but is available even when the XInput extension
is not supported.
DMXGetInputInformation
deviceId: CARD32
==>
inputType: CARD32
physicalScreen: CARD32
physicalId: CARD32
isCore: BOOL
sendsCore: BOOL
name: STRING8
Errors: Value
This request was first supported in version 1.1 of this protocol.
This request returns information about the specified input device
that cannot be obtained from the XListInputDeivices call. The
deviceId is the same as that used by the XListInputDevices call, and
must be in the range 0 to inputCount-1, inclusive (values outside
this range will result in a Value error).
The value of inputType will always be value, and will be one of the
following values:
0 for local (and dummy) devices,
1 for console devices, and
2 for back-end devices.
For local devices, all other fields returned, except isCore and
sendsCore, are invalid.
For console devices, the physicalScreen and physicalID will be
invalid, and the name will return the name of the X server on which
the console window is displayed.
For back-end devices, the physicalScreen will identify the back-end
display and can be used as an argument to DMXGetScreenInformation to
obtain more information; the physicalId will be the XInput device id
on the back-end X server; and the name will be invalid (since it
does not provide any additional information that cannot be obtained
with DMXGetScreenInformation).
If isCore is True, then this device is active as a true core input
device and will send core events. If sendsCore is True, then this
device queried an XInput extension device, but sends core events
instead of extension events. Note that this behavior is different
from that of XFree86, where XInput extension devices may send both
extension events and core events.
DMXForceWindowCreation
window: CARD32
==>
Errors: Window
This request was first supported in version 1.2 of this protocol.
When using the lazy window creation optimization, windows are not
created on the back-end X servers until they are required. This
request forces the immediate creation of the window requested.
DMXReconfigureScreen
screen: CARD32
x: INT16
y: INT16
==>
status: CARD32
Errors: Value
This request was first supported in version 1.3 of this protocol.
This request reconfigures the screen position to coordinates (x,y)
when using the Xinerama extension. Otherwise, it is a NOP. Illegal
values for screen will result in a BadValue error. Other non-fatal
errors will be returned in status.
DMXSync
==>
This request was first supported in version 1.5 of this protocol.
This request flushes all pending protocol requests between the Xdmx
server and each back-end X server. It is used by a client that
talks directly to back-end X servers
To ensure proper synchronization semantics, this request has a
reply, but the reply does not carry any information.
