4.4.4
=================
Fix a bug in Compute when comparing two strings of
different length using == (Bug #205)
Added a new algorithm for generating the neighbors
component for irregular cubic connections.
Update Refine for tetras to remove any degenerate
results. Only valid tetras are returned.
Fix a bug with hardware rendering where turning
on the transparency for all surfaces caused problems
with opaque surfaces within some GL codes.
Fix a bug in the quad interpolator where some results
could be returned as NAN.
Make it possible to change the way TMESH's are generated.
See docs for environment variable:
DX_HW_TMESH_ORIENT_SENSITIVE.
Correct a bug introduced with the Column Plot with
respect to using fixedfontsizes in Plot and Colorbar
(Bug #212)
Add the ability to have the executive pass more than
4095 characters to the UI or other DXLink apps. Useful
with JavaExplorer when passing something like a webpage
back in response to a pick.
Add the ability to set the Integer, Scalar and Vector
Interactor default caclulated output to the min, max
as well as the default midpoint.
Add the capability to be able to pass much larger
strings through the packet handlers. This will
accomodate sending full html pages through as responses
to clicks in Java Explorer.
Corrected a problem where some code would cause
problems when the compiler optimized aliasing (Bug #196)
Set the shared library flags to reflect the more
updated compilers on Linux (Bug #208)
Correct a Java Explorer server problem where a blank
line in dxserver.hosts would cause the server to die.
Fix a case for stricmp in Compute where the function
would return success when a was a prefix of b.
Added an option to Lookup to allow a different return
value if the item was not found.
Add a fix for hardware texture mapping where an error
would sometimes occur stating that the 'uv' component
didn't exist when it obviously did. This manifested
itself quite easily--just turn on AutoAxes with a
texture mapped field.
4.4.0

Fix for colors in the Colormap Editor when the OS's
depth is set to thousands of colors. (bug #134)
Fix for macros with space in their filename in the

Fix when using more than 31 labels on an AutoAxes. (bug #166)
Added a resize attribute to the ImageMagick format in order
to use the Lanczos Filter for reduction before saving an image.
Changed the default behavior of nested loops within dx. Now
the more time consuming but less crash prone TriangulateNestedLoops
is used instead of the faster simpler version. Can change with
the environment variable DX_SIMPLE_LOOPS
Fix for module builder crash (bug #162)
Fix for crash in exec when excluding a text based field
in select (bug #161)
Added some support for a Multithreaded exec (still a long

Typo in EditorWindow code
Disable debug info on GraphLayout code
Removed the "commercial" fonts from standard font popdown menus
Fixed a problem where adding an 'invalids' component did
not work correctly.
NULL terminate "Help on Syntax" string.
4.3
===============
Added the RTLD_GLOBAL to loading modules so that functions
between loadable modules are visible.
Fix a crash bug when a parameter value is set to "". It probably
happened only when the Display tool had a user-specified Where
param as would be the case with SuperviseWindow AND the user
did some operation like drag-n-drop, cut/copy/paste,
'Edit/Insert Program...'.
Added better handling of resize calls to an Image window
so that the update call isn't called continually with Window
managers that expose the image during resize.
Fix in the 2D quad interpolator where point is on edge.
Remove the new-line character on some new annotations to remove
the funny character at the end to be displayed.
Fixed up the JavaDX macros to include comments and put some of
them in the "" category so they do not show up in the UI.
Add a work around to fix a bug when the PageUp, PageDown, or End
keys were pressed and caused a crash. This is a bug in Motif < 2.3.
Fix the Tabbed windows so they have rounded corners even with
Hummingbird's Exceed without requiring Hummingbird to fix their
software.
Changed the tool selector to be a tree view type list and updated
all functionality to go along with that.
Implemented a preferences file that saves the state of the
tree view expansion from launch to launch. Also saves a list
of recent files that is now available in the File menu.
Fix for the random function in Compute for Windows version.
(Bug ID#66)
Fix the module builder to work and use CR/LF on DOS based
systems. (Bug ID#109)
Fix the activation of application wide commands unless the
Network object == the application's main network. (Bug ID#106)
Fix problem where a large stream going to the message window
on Windows would Quit the Exec (Bug ID#107)
Converted dxworker to bourne shell from csh. Now allows spaces
in filenames and exe names and better handles special characters
passed in to the exec with scriptcmd option.
Corrected problem where Gamma was not being applied to images
saved via ImageMagick (Bug ID#67).
Added capabilities to affect the compression method and quality
in images saved with ImageMagick.
Fix a memory leak in the XHandler within the EditorWindow.
Fix a memory leak with respect to the rotation globes and cfg files.
Fix a memory leak with open file descriptors on systems with
HAVE_OPEN_DIR and HAVE_DIRENT_H. Free regular expression compiled
with regcomp.
Fixed the placement of the Throttle dialog of the Image window.
Fixed a problem with the Frame Control of the Sequencer popping
up directly over the Sequencer on the first pop-up.
Fix "Visualize Data..." in the prompter to pass unix path
separators instead of DOS on Windows machines.
User Interface performance improvements.
New option under the edit menu for automatic graph layout, which
rearranges the nodes in the graph of the current vpe page.
Pros n Cons:
- It ignores the current layout. That can be pretty disorienting.
- If the graph has connections going all over the place and doesn't
use transmitters,receivers then the output might not be any better
than the input.
- It works stupendously on many graphs especially those that don't really
need to be rearranged.
- What looks good and what looks bad is pretty subjective.
Undo now available in the editor window.
How's it work:
Every node or annotation move in the canvas is recorded and
can be undone via Ctrl+U (Ctrl+Z).
Cursor keys now affect module movement on the VPE. Helps people
who lay out nets really carefully. Now it's easy to make small
movements and you get to see the lines redrawn as the node moves.
How's it work:
Select a node(s) or annotation. Then use up, down, left, right
arrows to move the selected objects 1 pixel at a time.
There is some code for reading in Selector interactors out of .net
files that was cleaned up and corrected.
Fix a memory leak in configuration dialog boxes.
Bug ID#45
Implement OPTIONS processing on behalf of macros. Now possible
to add drop down options on Macros. Use semi-colons to separate
items of the list.
Fixed Bug ID#18
EditorWindow destructor was deleting cache-optimization menu
items twice, now only once.
Fixed Bug ID# 38, 61
Object deleted during the dropFinish callback. The new Motif
interprets Widget deletion as a need to cancel drag-n-drop which
triggers the dropFinish callback a 2nd time. Problem is object
already deleted. Now, object deletion is queued so object is
deleted from dropFinish callback.
Fixed Bug ID#10
Set Min Width, Height on the container so it can't be resized
to small.
Added isnan functionality for Windows in stat functions.
Added isnan and finite to the Compute module for those systems
that support it.
A fix for Streamline when checking for Invalid Data components.
A correction to check to see if "invalid" components are added
then recompute "dep" components.
Added Visual Studio loadable modules example.
Fix for invalid() to return error instead of crash in Compute.
A correction for netCDF where an invalid file would crash OpenDX
instead of returning an error.
DXTrimItems() has been added as a function to remove items from
the end of an array.
Incorporating some native Windows code to begin making a Windows
native executive.
Began adding WIN32 support and building with Visual Studio 6.0. Due to
some bugs in Visual Studio 7 (which are acknowledged by MS), we will
not be able to build with VS7 until fixed.
For libtool purposes and the new work on making a thread safe exec,
the yacc code must be parsed with bison. Thus we are adding the
generated *.c files in the cvs tree and in for distribution.
Now building with libtool to allow dynamic libraries to be built. This
required updates of some global variable initialization and renaming
some files to be unique in the libraries.
4.2.0
===============
Java Explorer's macros have been updated to reflect the removal of the
gif image format internally from OpenDX. They have also been renamed
to use the standard DX naming convention uc/lc. This will require any
user networks to be opened and saved with 4.2.0 before serving them
up with JavaDX.
Fix to update multiple DrawingArea windgets with the same size during
expose event.
On a multiple image display windows application, the key value computation
on hash() function on libdx/notify.c is too simple. Two different input
parameters will return same key value. The result is the system runs out
of memory. For example: "CACHED_OBJECT_X24,:0,#X205520899" and
"CACHED_OBJECT_X24,:0,#X184549379" generate same l value 73. Adding one
more factor "s" the sum of character string will reduce the probability
of same key value return.
Added the ability to use a web browser and the html documentation
as the DX help viewer. To enable, under UNIX set the environment
variable DX_WEB_BROWSER to your web browser. Under Windows and MacOS X
set this environment variable to anything and the system default
browser will launch. Due to bugs in Exceed XDK and MacOS X (Bug ID#2879972,
#1951588) their may be some annoyances using this feature.
Added a new keymapping scheme -- a new set of accelerators. This new
set of accelerators follows the Windows, MacOS, KDE styles. This is
enabled during compilation as a configure flag.
Update to allow the user to specify their own object colors (via
the "colors" component) to light and modulate a hardware rendered textured
object, instead of accepting the hard-coded solid white. "opacities" can
now be defined and used as well.
Activated linear interpolation and mipmaping texture filters.
For OpenGL (hardware) rendering mode, adds the following field
attributes that affect culling and lighting:
attribute "cull face" string ["off"|"front"|"back"|"front and back"]
attribute "light model" string ["one side"|"two side"]
and the following field attributes that affect texturing (when the
"texture" attribute and "uv" component are also correctly provided of course):
attribute "texture wrap s" string ["clamp"|"repeat"]
attribute "texture wrap t" string ["clamp"|"repeat"]
attribute "texture min filter" string \
["nearest"|"linear"|"nearest_mipmap_nearest"|"nearest_mipmap_linear"|
"linear_mipmap_nearest"|"linear_mipmap_linear"]
attribute "texture mag filter" string ["nearest"|"linear"]
attribute "texture function" string ["decal"|"replace"|"modulate"|"blend"]
Note that "light model = two side" is particularly useful when
lighting polygonal models with no normals where the auto-computed normal
may bear no resemblence to the "outside" of a rendered object (without it,
only software rendering in DX is worthwhile). The rest are useful when 3D
polygonal models that require specific culling and texturing state for
correct display are integrated into DX visualizations.
--Note that the default OpenGL state when these attributes are not
specified is the same as it was before.
--Also, now that texture maps are registered via gluBuild2DMipmaps in
the OpenGL back-end, the restrictions on supplied texture maps being powers
of two and larger than >= 64x64 is no longer the case in general, so the
checks have been removed. Back-end specific checks can be added later if
other back-ends are still used.
Fix for expanding CDB boxes on LessTif systems.
Much needed updates to some of the html documentation. It now includes
a client side search engine provided using JavaScript.
Support OpenGL 1.3's GL_CLAMP_TO_EDGE texture wrap mode in the OpenGL back
end; support via extension for OpenGL 1.2.
To activate, set the "texture wrap s" and/or "texture wrap t"
attributes on the field to be textured to "clamp to border" (instead
of "clamp", "repeat", or "clamp to edge").
Updates to allow compiling with SGI n64 ABI
Corrected a problem with lex/parsing of programs from the UI after
and error occurs when trying to open a network. A consecutive open
now works correctly and does not give false error messages.
Added TypeAhead functionality to the tools list of the VPE. With Motif
2, this functionality was minimally there, but my additions extend it.
To use it, place the mouse over the Tool List and begin typing the name
of the module you wish to use. Other keys other than alpha that affect
this are: Up, Down arrows do the expected. Space bar deselects the tools.
Add translucent texturing with alpha blending support to the OpenGL
hardware rendering back-end.
Intuitively, translucent textures are represented as image fields with
opacities components -- either float opacities, or ubyte opacities and
a float opacity map. (FWIW the ImageMagick ReadImage mods I made back
in Sept '01 read translucent images to this field format)
As with opacities objects, translucent textured objects aren't meshed,
are tossed into the translucent SORTLIST, sorted by depth, and rendered
with the DrawTransparent back-end callback.
Various related changes such as:
- Suppress Z buffer write for fully-tranparent alpha values
- Display list texture activation ops in DrawTransparent, as is done
in DrawOpaque
Also, it fixes texturing support in general for texture composite field
objects which have ubyte[3] or float[3] direct colors (didn't work
previously).
A fix for the Ellipses page selector. Now when you click on the Ellipses
if it's popped up, it will pop back down (like other Motif menus). It
also now initially opens up with a height of 12 lines instead of 1 line
(which was very annoying).
Removed Xm errors when Grid Dialog box displayed.
Added a Mode menu to the Option menu in the Image Window. This allows
direct access to the image manipulation routines without having to
remember the shortcut keys or open the View Control dialog. It also
adds some increased functionality internally to the code by removing
the dependency on X based accelerators in the Picture widget.
Mapped the following accelerators from the VPE to configuration dialogs
- save program accelerator
- all the execute menu accelerators
- add and remove input tabs
Added the functionality to allow the accelerators to be mapped onto
subpanels that can be popped up from the Image Window. The accelerators
now work in:
- View Control (always has, but is now handled the same as the others)
- Auto Axes (can now click apply and then use accelerators--handy)
- Rendering Options (very nice to click hardware then execute once)
- Throttle (to be consistent)
All the accelerators such as Save, Print, Close all work in the sub-
panels giving a more consistent feel to the ImageWindow.
Fix Selection color on Selector List Interactor so the selected
value is visible.
Fix Background on Selector Option Menu so the menu is green in the
developer mode.
Fix the Control-Click on Close of a user style Control Panel to
work as described.
Fix the attribute copying logic for Band since Isosurface creates a
separate field for each isosurface, Band creates only one.
Added DX_SOCKET_BUFSIZE environment variable allowing the user to
specify the size of the send and recieve buffers for the socket
connection between the UI and the exec. This provides a fix until time
permits to write the significant logic change to make the UI interlace
reading data from the exec and writing data to the exec. This value
is clamped to the max allowed by the system. This can fix a problem
where the executive and UI hang involving a deadlock situation in the
socket communication. The value assigned to it is passed as the parameter
to setsockopt for SOL_SNDBUF and SOL_RCVBUF. I think the default is
32767. A typcial value may be 262144.
Fixes to to prevent hanging processes if the UI disconnects from the
server while the server is running.
A fix where some Packet logic could core dump.
Added MacOS X memory routines for the Executive. Added MacOS X arch
dependent info needed.
Added configuration flags to make it possible to build loadable modules
with Windows.
Fix bug where field with ubyte colors (refing a float[3] colormap), which
is constructed by ReadImage and storable with Export, won't load with
Import. Patch allows general UBYTE components to ref other components in
Import.
Changes to the way invalid components are handled so that two thresholds
are used: one for storage in an Array (20% of total values, as before)
and another for building the InvalidComponentHandle for transient
processing (currently 1024); small size for storage and faster access
performance. SORTED lists are always converted to HASHes or DEP_ARRAYs
now for processing (as they were when originally created), not left as
SORTED_LISTs.
Fixed bug in computing conncetion-dependent normals for 2-D positions.
Of course, the real question is whay are we computing them at all?
They'll be {0.0 0.0 1.0}.
Permit invocation of script functionality from the command-line via:
dx -script script_macros.scr -scriptcmd "MyMacro(value1,value2)"
or
dx -scriptcmd 'data = Import("junk"); Print(data);'
without requiring the user to use shell scripting tricks or build temp
script files.
Add ImageMagick support to ReadImage.
- Works with ImageMagick 5 (tested with 5.3.7)
- Reads images from PNGs, GIFs, MPEGs, Postscript files, etc. --
whatever support your ImageMagick library was built with
- Creates opacities/opacity map components for images which have
opacities or a transparency map (e.g. GIFs, PNGs, ...); use Render
- Supports both delayed and direct color images, with delayed->direct
option and float/byte option
- Smart chomping of supported ImageMagick extensions
- Supports DX convention for reading multi-frame multi-file sequences;
e.g. name="t.gif", where images are t.0.gif, t.1.gif, t.2.gif, etc.
- For multi-frame single-file images (e.g. animated GIFs, stacked
TIFF/PNGs, etc.), only loading the first image is supported
(ImageMagick is missing basic sub-image support; see the source
comments for details).
Ugly but overdue changes so that ImageMagick can write files directly
without dx writing an intermediate miff file.
Added support for polylines to the opacity renderer.
Fix error where Sample would core dump on Sampling lines.
Within Isosurface, was trying to interpolate all components that are dep on
positions. In some cases, invalid positions components are positions-dependent;
made it skip them.
Fix to make dxexec release processor when in wait loop. This fixes the
99% CPU usage on NT.
Fix to allow clicking off Connect to Already running server in the Options
dialog box.
4.1.3
===============
Fixes to several problems that quickly arose with 4.1.2
---------------------------------------------------
- Dependencies of source files on built sources caused build to stop.
It would continue correctly after restarting, but by making the objects
dependent instead we made it work in one pass.
- References in _regstream.c. Missing references/deletes in _regstream.c
and steamline.c caused objects to be really deleted before their time.
Problem appeared in ThunderStreamlines example. Did this ever work?
- Not enough memory allocated for buffer in parse.c.
- Needed to pass in class_srcdir value to invokation of class script
in libdx/local.mk
- Include net2c in distribution
- Correctly free search_for in Browser.C. Proper behavior dependent on
compile-time definitions.
- Not enoucgh memory allocated for type-in string in GARApplication.C.
Caused segfaults in prompter.
4.1.2
===============
Distributed-memory extension to OpenDX
---------------------------------------------------
dxmpi checked in as a new part within OpenDX. No significant documentation
has been written.
dxmpi works by starting an instance of the DX executive on each MPI
host, with one (rank 0) designated the master. The master communicates
with the UI or directly in script language (though rather than by typing
directly in, a separate program is used to connect the keyboard to dxexec).
Absent any use of OpenDX-MPI extensions, the master performs as a
completely normal OpenDX exec.
The MPI extensions to OpenDX fit two forms: modules that appear to run on
the master but which use MPI internally to run in parallel, and macros that
are run in parallel on the slaves at the behest of a "RunOnSlaves" module
that runs on the master. I've put in an API allowing modules to register
and call remote procedures and to pass DX objects around to support the
first type. For the second, there's a set of new modules that provide
tools for data distribution from the master to the slaves, leaving the
distributed data as named objects in the slaves' cache, where they can be
retrieved by name by macros run on the slaves by RunOnSlaves.
As an example of the first type, a parallel regular-grid importer
(DRegularImporter) that works like this. As inputs, it receives
the name of an ad-hoc data description file that describes the layout of
data found in a separate file. It registers a remote procedure with the
slaves, and then invokes that procedure on the slaves, passing them the
data description and a destination object name. Each slave, knowing how
many slaves there are and its own rank among them, is able to determine
what portion of the data its responsible for (essentially, partitioning the
data as a part of importing it, and including a "ghost zone" of overlap
with neighboring partitions). Each imports its part, saves it in the
cache under the destination object name (the same on all slaves), and
returns the bounding box and min max of its partition to the master. The
master (still in the guts of the DReguarImport module) gathers this info
together into an output Group object where member i is the box and minmax
of partition i residing on slave i.
Now suppose you want to isosurface and render that data. You create a
macro on the slaves that accesses the data by the name under which
DRegularImporter left it and an isovalue (again by name, from the cache).
The macro then sends the data through Isosurface and Color and whatever,
then passes that result to the SlaveDone module, which indicates to the
master that the execution of the macro is complete and returns the object.
On the master, a scalar interactor feeds the input of Broadcast(value,
name) that broadcasts the interactor's value to the slaves under the
associated name. The dummy output of Broadcast and the output of
DRegularImporter are passed to "control" inputs to RunOnSlaves(macro name,
control ...) that just serve to ensure correct module sequencing.
RunOnSlaves causes the slaves to run the named macro, waits for their
results, and gathers it all together in a group where member i contains the
result of slave i. This could then be passed directly into Image for
rendering.
There are a couple other cool pieces to this, most notably a distributed
parallel renderer and a new streamline module that runs on distributed
vector fields. There are a lot of holes to fix; for example, errors in
slave macros very often cause system hangs. There is no integration of the
notion of slave macros into the UI. Lots of things.
Added command-line arg to configure for compatibility with ddx. Either
way the resulting code works exactly as before, but if --enable-ddx is set
the libraries will work with ddx.
Implement compatibility with ddx, which requires code in the main loop
to check for input from MPI. ddx.c is a stub file, so whether or not
--enable-ddx, the dxexec built in the source tree works as before.
---------------------------------------------------
Added mechanisms to directly connect OpenDX to other processes.
Includes a new module, SocketConnection, that supports sending objects
from an external process to OpenDX across a socket (and back, as a
future enhancement). The idea is that the process makes a call to
see if an OpenDX instance has opened a port. If it has, it can send data
to OpenDX by creating an object using the data model calls in the DXlite
library, buffer it, and write it to the socket. On the OpenDX side,
SocketConnection creates a port and an associated fd, then adds an input
handler to watch for input on the fd. When input arrives, its read off the
socket and converted to a DX object via _dxfImportBin_Buffer, and
DXReadyToRun is called to indicate that new data is available. When the
module runs, the received object is the module result. This allows the
external process to send arbitrary objects to OpenDX across a socket.
Added a new subclass of Array to further assist with direct connection.
A SharedArray is very similar to a generic Array, but allows the array
contents to be shared with the external process directly. When a
SharedArray is created, DXNewSharedArray is given a shared memory segment
ID and the address of the data, which must lie in that segment. Unlike
generic Arrays, which copy data using the DXAddArrayData call, SharedArrays
use it directly. DX keeps track of how many SharedArrays reference each
segment, and maintains an attachment to that segment as long as there are
references to it. When the external process creates an object containing
a SharedArray, the buffering process transmits the segment id and offset
within the segment to OpenDX. When its unbuffered, a new OpenDX-side
SharedArray is created, the segment is attached (if necessary - it may have
been seen before), and the SharedArray stores the address of the data in
OpenDX' memory space. Thus the external-side SharedArray (which itself
shares data with the external process) and the OpenDX side SharedArray
actually share memory.
Support for SMP linux boxes:
Since this is not well tested it is an optional make- --with-smp-linux
on the configure command line. The memory available to OpenDX in SMP mode
is limited to the max size of a shared-memory segment. This may be set
low and must be changed in /proc/sys/kernel/shmmax. Created inter-process
locking from IPC semaphores, and its not confidence-inspiring.
Fixed a bug in the handling of the deletion of task groups in task.c.
RSH enhancements:
- configure now picks up system rsh and bsh or is setable by the user.
- The default command "rsh" has been left in place, but
a user-specified remote shell command can be specified via the
$DXRSH environment variable. Example: setenv DXRSH /usr/bin/ssh
- FQDNs (full host paths) are used under the hood when available
when creating the remote "invoke dxexec" script and connecting
back to the master exec,
- Users can now enter host names of the form "user@machine" in
the Execute Group Assignment... dialog, and
- setting the $DXRSH_NOENV in the local environment prevents the
remote "invoke dxexec" script from being written with a full
carbon copy of the local environment (only $DISPLAY is set).
- dumped pcreateve on SGI in favor of vfork/fork and exec for
kicking off rsh.
Correctly avoiding a memory leak with hardware rendering due to a mysterious
reference.
Add the capability to change the logo and splash screen by adding a
hook into the Xpm libraries. Now users can customize if they so desire.
New Regrid option of Radius 0 that basically performs a snap to grid
functionality. This option will make regrid apply data to the nearest
grid position and average it if there are multiple (not weighted).
Initial support for MacOS X. It appears that there are quite a few bugs
in 10.0.2 still so it may have to wait a little longer. Also, somebody
needs to work on the memory routines for OS X.
Further corrections for the Windows code versions. Updated several
places where the DOS path may get munged. Updated JavaDX to be able to
pass in DOS pathnames to start the server.
An addition made to edfparse to allow the creation of a local reference
to an external file within the native file format. This local reference
can then be used repeatedly within the other objects without having to
reread the external file.
(Example:
object "localobj" file "externalfile.dx",1
object "f1" field
component "positions" "localobj"
object "f2" field
component "positions" "localobj"
)
A correction to the edfparse to accept data description in the native
file format with object names as references instead of numbers.
A correction to isosurface to pass attributes through not remove them.
Fix to make CDBs open at correct opening width when scrollbar is needed.
Modifications to avoid glx functions not implemented by wiregl.
Some memory leak patches to general import, task, and redce.
Now installing the built dx.mdf file so that the BSpline
module is now visible in the VPE.
Add functionality to SuperviseWindow to use a camera to set the
window size.
If DXMDF env variable is set to NULL then an error occured. Check
it first before trying to open it.
Fixed SMP OpenDX to use parent process and fork in a better
order. Didn't change the default behavior.
A fix in the List module that could go past array bounds.
A fix for DXcallm that allows Rubbersheet to be used again.
A small memory leak fixed from not closing a message file.
Fix in the Tube module that could cause a possible core dump.
Provided a fix in dxworker so the exec could launch on Solaris 2.8.
Cleaned up the warnings in src/exec/libdx, src/exec/dpexec,
and src/exec/dxmods -- this included adding header files and
removing many of the extern prototypes making APIs more
usable.
Added the functionality to build C++ modules from the module
builder.
Fixed a possible memory leak in the Post module.
Added Randall Hopper's lock fixes to decrease execution
time on single processor machines by 20%.
Added Randall Hopper's module path fix that can decrease
execution time on cached networks significantly.
Dropped support for ImageMagick 5.1.1 and added support for ImageMagick > 5.2.
ImageMagick < 5.0 support still exists.
Added support for compiling with Microsoft compilers. Updated much
of the Windows environment setups.
Added more support for the AIX xl series of compilers.
Correction for 2D Map when point is on edge it is detected.
More cleanup to JavaDX. DX_JAVA_CLASSPATH is now the variable that
stores all classpath info. Removed the multiple ones of Netscape and
WRL.
Added support in configure to work with ImageMagick's Magick-config,
thus reducing the amount of checks that are required when configuring.
4.1.0
===============
With this revision, a lot of the Gnu AutoConf stuff was cleaned up to
help improve building the package from the source code.
Many updates to the AutoConf build routines for JavaDX. JavaDX should
now build readily on all systems.
Added new configuration options to disable building some libraries and
JavaDX. Added options to direct where java files reside if they can't be
found: --disable-buildlibdx --disable-installhtml --without-javadx
(remove compilation alltogether)
--with-jni-path=/PathToDirectoryContaining-jni.h:/PathToDirectoryContaining-jni_md.h
--with-cosmojar-path=/PathToCosmoJarFile/cosmoFileName.jar
--with-java40jar-path=/PathToJava40JarFile/java40.jar
The internal copyright mechanisms all get updated from the configure
scripts this makes tracking versions from the user interface easier.
Some general source code clean-up was done, there will be much more to
come in the next set of revisions.
OpenDX-generated makefiles are now largely platform independent as
created. To the extent that they have platform dependencies, these are
(or should be) determined by dx configure and written into arch.mak.
This allows the module builder to generate makefiles compatible with
OpenDX, such that runtime loadables work on a number of platforms and
dxui now writes compatible makefiles for building and installing JX
applets.
Problems with Interactors not working properly on some systems is fixed.
Linux binaries can now use loadable modules.
dx script is now stored in two locations during installation in case the
installation is moved and /usr/bin/dx is forgotten to be collected.
name change of dx.workerscript to dxworker
defaulting of the environment variable of DXMACROS, DXDATA, and DXROOT
if they are not set.
added -whereami option to dx to detect location of dx install
LD_LIBRARY_PATH is not overwritten on Solaris but just added to now.
mdf2c is now constructed with appropriate open source paths.
Help files links and install should now be correct after installation.
Added support for 15 bit and 32 bit color displays.
Added outboard.c to source tree to be included with outboard modules.
Added support for including libraries from ImageMagick build into
libDX.a. If the libraries are shared, then they are not added and must
be linked at a later time.
Forced Linux versions to run as single processor only not SMP until
shared memory is correctly addressed.
Fixed a memory leak where if DXMACROS was set, it would tromp on memory.
This is now fixed and relieves many core dumps in the exec.
Removal of some hard coded geometries on dialog boxes to make dialogs
work better with Lesstif. So far no reports of any problems with Motif.
Added support for using ImageMagick. If ImageMagick is available during
compilation, then many more image export formats will be available by
choosing the ImageMagick formats.
Correction to AutoRegrid module. "infinity" used as the radius caused a
core dump. This did not show up with all compilers.
Fix in Colorbar to make positions "dep positions". Fixes compliance with
some other tools.
Fix in the Enumerate module for properly creating counts.
A few minor fixes with the import routines for HDF and netCDF.
Corrected typos in module SimplifySurface.
Correction in Stack module for series data.
libDX is now being built correctly so modules can be linked to it with
proper functionality.
Added functionality for dx to use its default memory rules on linux. Fix
for possible negative memory request.
Correction to quads for possible loop when point coincides with vertex.
Correction when a point is on the line containing an edge. Need to check
sign.
Fixes to allow FreeBSD to compile correctly.
A correction the Grid Dialog box. Some testing may still be in order.
A error with postscript printing the networks was corrected.
Correction in the Browser for a pointer to an array.
Clean up a lot of the Motif function calls prototype mismatches.
4.0.6
=============
First initial stable release.
4.0.3
=============
Added code to makefiles and c files to create libDX, libDXlite, libcallm
Fixed missing splat in WorkspaceW.c
Removed apparently unnecessary code referring to
_XmDestroyParentCallback
Changed configure to look for old versions of Lesstif and set
OLD_LESSTIF, rather than any version of Lesstif and set USING_LESSTIF
HP_UX -> HP-UX
More general test for cygwin
install change - mkdir dx/bin rather than use INSTALL
configure test for sys/select and use in PacketIF.C
