Found in the join file the fix for the bug found by Rafa.
Problem :
osgIntrospection::Value grp(new osg::Group);
osgIntrospection::ValueList vlcall;
vlcall.push_back(osgIntrospection::Value("toto"));
const osgIntrospection::MethodInfo *m =
grp->getType.getCompatibleMethod("setName", vlcall, true);
if (m)
{
m->invoke(grp, vlcall); // ** SEGFAULT here
}
Algorithm explanation :
The "invoke" method try to convert "grp", which reflect an
"osg::Group*", in a
"osgIntrospection::Value", which reflect a "osg::Node*".
This because
the "setName(const char *)" method found by
"grp->getType.getCompatibleMethod"
is an "osg::Object" type method.
When osgIntrospection do this conversion it try :
- to found a "osgIntrospection::Converter" to convert
from "osg::Group*" to "osg::Node*"
- to found a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
- to converte an Enum to int or unsigned int
- to convert the value in its "value string representation",
then converte this string in the destination value
Else it throw a "TypeConversionException".
Bug :
1)
When osgIntrospection try to found a chain of
"osgIntrospection::Converter"
It could do any downcast or (Type to SuperType) or upcast
(SuperType to Type).
This mean the the chain could be :
osg::Group to osg::Transform to osg::Camera to
osg::CullSettings to osg::CullStack to
osg::CollectOccludersVisitor to
osg::NodeVisitor to osg::Referenced to osg::Object
During the convertion with this chain, A METTRE failed and
the pointer in
"grp" is set NULL. But the "grp" is always a valid
"osgIntrospection::Value"
and so, osgIntrospection accept the conversion. Then it try
to use this pointer
to call the "setName" function. And Bing SEGFAULT.
2)
In "bool Reflection::accum_conv_path( ... )"
the convection path isn't accumulate in the recursive loop.
this cause multi request of a conversion path, and a
slowdown in the
conversion algorithm.
3)
Use of the last conversion way in a conversion from
pointer to pointer
this mean you can do this :
"osg::Node*" to " value string representation" to "osg::Material*"
What a bad thing !!!
Solution :
1)
Introduce the concept of dynamic_cast and static_cast.
now, to do a conversion, osgIntrospection does this :
- to found a "osgIntrospection::Converter" to convert
from "osg::Group*" to "osg::Node*"
- to found a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
only with static_cast, downcast (Type to SuperType)
- to found, if the source and the destination are two pointer,
a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
only with dynamic_cast, upcast (SuperType to Type)
- to convert an Enum to int or to unsigned int
- to convert the value in its "value string representation",
then convert this string in the destination value
Else it throw a "TypeConversionException".
Add the "enum CastType" to distinguish the static_cast or
dynamic_cast converter.
Add file OpenSceneGraph/include/osgIntrospection/CastType
2)
add a line to accumulate converter in converter Path.
3)
add a line to check if source and destination are pointer.

Stephan: "attached you'll find some modifications to the GraphicsWindow-class and
their platform-dependant implementations.
The problem:
setWindowRectangle and setWindowDecoration do not update the
traits-object, so, if you call setWindowRectangle on a
not-realized-window it will open with another size when realized later.
getWindowRectangle reports possible wrong sizes if setWindowRectangle
called before.
My solution:
split the implementation in two parts:
GraphicsWindow::setWindowRectangle will update its traits-object and
call afterwards the virtual method setWindowRectangleImplementation
(which is implemented by the derived platformspecific classess). For
setWindowDecoration I am useing a similar mechanism.
I hope you'll find the submission useful, the Win32 and X11 changes are
not tested but should work."
Changes to this made by Robert are call of resized in setWindowRectangle
instead of setting of Traits, and use of a bool return type.
changes I made:
+ put a warning in the console if a nonexistant screen is requested
+ add getters for the aglcontext and pixelformat -- I need access to
them in my own code.

the declaring file for a given type via the new member function
osgIntrospection::Type::getDeclaringFile. This information is useful
in order to know what header to include when auto-generating wrappers
for a given type.
During the C# wrapper generator development I've been keeping the
declaring file configuration state up-to-date manually with changes
to OSG, and it's proven to require substantial effort. So it would be
extremely valuable to get this change in before 2.0 to reduce maintenance
during the lifetime of the release. It'll also be equally useful to
others looking to create wrapper generators using osgIntrospection.
This is a fairly simple change and was tested with a fresh rebuild of the
entire suite of osgWrapper libraries, so it should be relatively low risk
(fingers crossed)."
that the terrain is always the Earth planet. I changed the constructor
method to accept the Equator radius and the Polar radius like
parameters. By default, it assumes the Earth radius for the
EllipsoidLocator. I added a setEllipsoidModel method, too.
Now, we are developing some libraries for a GIS applicacion, and our
libraries can visualize terrains of planets like Mars. I think that is
a interesting change."
I added _preDrawCallback member and neccessary access methods plus modified osgUtil RenderStage.cpp to invoke it before all drawInner calls are made. I tried to maintain symmetry with postDrawCallback but you know better where is a proper place for this call ;-)

window.
The win32 implementation is still in its original shape since I have no win32
implementation available.
I have chosen the enum approach for the first cut. That is benefitial since
the user does not need to track creation of mouse cursors for different
windows and displays in presence of multiple viewer windows.
The default set of available mouse shapes is the same set that was available
with glut. That set served many OpenGL applications well, so the hope is that
this is enough.
Even though, that implementation is still extensible:
I have digged out the way SDL defines new mouse cursors and added a still
documented out function prototype in the GraphicsWindow that can be used to
extend the current implemtation for arbitrary mouse shapes. That is not
implemented yet.
I hope that somebody with a win32 test system can catch up that implementation
on win32."
The major modification concern the LineProjector class in Projector.cpp. The intersection was previously done in window space, I've modified it to compute it in object space."
"Since we desperately needed a means for picking Lines
and Points I implemented (hopefully!) proper geometrical tests
for the PolytopeIntersector.
First of all I implemented a new "GenericPrimiteFunctor"
which is basically an extended copy TriangleFunctor which also
handles Points, Lines and Quads through suitable overloads of
operator(). I would have liked to call it "PrimitiveFunctor"
but that name was already used...
I used a template method to remove redundancy in the
drawElements method overloads. If you know of platforms where
this will not work I can change it to the style used
in TriangleFunctor.
In PolytopeIntersector.cpp I implemented a
"PolytopePrimitiveIntersector" which provides the needed
overloads for Points, Lines, Triangles and Quads to
the GenericPrimitiveFunctor. This is then used in the
intersect method of PolytopeIntersector.
Implementation summary:
- Points: Check distance to all planes
- Lines: Check distance of both ends against each plane.
If both are outside -> line is out
If both are in -> continue checking
One is in, one is out -> compute intersection point (candidate)
Then check all candidates against all other polytope
planes. The remaining candidates are the proper
intersection points of the line with the polytope.
- Triangles: Perform Line-Checks for all edges of the
triangle as above. If there is an proper intersection
-> done.
In the case where there are more than 2 polytope
plane to check against we have to check for the case
where the triangle encloses the polytope.
In that case the intersection lines of the polytope
planes are computed and checked against the triangle.
- Quads: handled as two triangles.
This is implementation is certainly not the fastest.
There are certainly ways and strategies to improve it.
I also enabled the code for PolytopeIntersector
in osgkeyboardmouse and added keybindings to
switch the type of intersector ('p') and the picking
coordinate system ('c') on the fly. Since the
PolytopeIntersector does not have a canonical
ordering for its intersections (as opposed to
the LineSegementIntersector) I chaged the
implementation to toggle all hit geometries.
I tested the functionality with osgkeyboardmouse
and several models and it seems to work for
polygonal models. Special nodes such as billboards
do not work.
The next thing on my todo-list is to implement
a an improved Intersection-Structure for the
PolytopeIntersector. We need to know
which primitives where hit (and where).

some discussions on the mailing list last week.
This is implemented through a new traits flag

setActiveTextureUnit methods of osg::State so they return false if the
texture unit is outside the range of allowable units for the driver.
Currently, the functions would return true even if the units are
invalid. This would cause the osg::State to become out of sync with
the actual driver state, which can cause some bugs in certain cases.
The change I made would verify that the unit passed to
setClientActiveTextureUnit is below GL_MAX_TEXTURE_COORDS, and the
unit passed to setActiveTextureUnit is below
max(GL_MAX_TEXTURE_COORDS,GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS). I
modeled this behavior from the OpenGL docs for these commands which
can be found here:

"By repurpose, I'm creating a new plugin that uses much of the .osg fileformat,
but with some changes. Specifically, I'm creating a ".osgfs" plugin, which
represents the scenegraph hierarchy as a filesystem of nested subdirectories and
individual files for each node, rather than nested braces with everything in a
single monolithic file. I intend to incorporate file alteration monitor events
to watch the filesystem for modifications and automatically reload.
The problem I'm running into is osgDB is too tightly coupled to the .osg format.
osgDB::Output::writeObject() contains literal .osg format-specific strings like
"{" to represent the Object hierarchy at too low a semantic level. I propose
using virtual methods; my plugin can then derive from osgDB::Output and
represent Object hiearchy differently.

This is a simple change to permit databases other than those named
"*.osga" to be used. It is hardcoded in read() at present.
It is non-critical and does not affect existing program functionality.

ArchiveExtensionList;
a list of extensions: ArchiveExtensionList _archiveExtList;
and an "add" method: addArchiveExtension(const std::string ext)
This is initialised by adding "osga" in Registry() and used in
Registry::read() where the list is searched for the extension used.

Removed the osgTerrain::ArrayLayer as its no longer required thanks to the above change
which makes the osgTerrain::HeightFieldLayer more flexible.
Updated wrappers
Lost the functionality to find the real type pointed by a pointer.
Ex: a osg::Node pointer point on a osg::Group, if I look for information
on the pointer type, the introspection say it is a "osg::Node*".
But if I want information on the pointed type,
the introspection must return the "osg::Group".
This bug come from the osgIntrospection::Value::Ptr_instance_box::ptype() function.
In the original version, this function use the member "Instance_base *inst_"
like this :
typeof(*static_cast<Instance<T> *>(inst_)->_data)
But in the new version, this function use the template argument "T":
typeof(typename remove_pointer<T>::type)
This is a good meta-programming use, but here we need a dynamic request.
Moreover the "typeof" macro define in "Reflection" header accept only a type in parameter with the new version.
fix:
Add the macro "typeofvalue" in "Reflection" header which accept a value or a type in parameter.
Restore original code in osgIntrospection::Value::Ptr_instance_box::ptype() function.

Vivek's email to osg-submissions:
"I'm happy to release the osgdragger nodekit to the OSG community. I
implemented the nodekit for my company, Fugro-Jason Inc., and they
have kindly agreed to open source it.
The nodekit contains a few draggers but it should be easy to build new
draggers on top of it. The design of the nodekit is based on a
SIGGRAPH 2002 course - "Design and Implementation of Direct
Manipulation in 3D". You can find the course notes at
http://www.pauliface.com/Sigg02/index.html. Reading pages 20 - 29 of
the course notes should give you a fair understanding of how the
nodekit works.
The source code also contains an example of how to use the draggers."
To set up extension aliases using a config file, an app calls:
osgDB::Registry::instance()->readPluginAliasConfigurationFile(), passing in the file name as the parameter. (Of course this should be done before loading any files whose names depend on the mapping.) osgDB will search for the file using OSG_FILE_PATH.
The file should contain a line for each mapping, with the "map" extension first, followed by a space or tab, then the plugin identifier. For example, a file containing this line:
flt OpenFlight
would map the ".flt" extension to the OpenFlight plugin."

on the screen, it looks more aesthetically pleasing to have a larger
gap between lines than is given by default. I added a new parameter,
lineSpacing, in the Text class to allow the line spacing to be adjustable
by the application. The default value is 0 meaning there is no extra
spacing given. The value should be given as a percentage of the character
height. A good value for longer paragraphs is 0.25 (25%) or more."

* Setup proper pixel format for ATI boards (removal of WGL_SWAP_METHOD_ARB specification from the requested pixel format since unsupported by the ATI driver)
* Fix to create sample OpenGL window on the proper display device. This is the temporary window used to choose the desired pixel format. In the previous version, this window was always created on the primary display device, even though it had potentially different pixel formats compared to the target display device containing the window to be created.
* Implementation of WindowingSystemInterface::setScreenResolution() method
* Implementation of WindowingSystemInterface::setScreenRefreshRate() method
* Implementation of GraphicsWindow::requestWarpPointer() method
* Implementation of GraphicsWindow::useCursor() method and associated trait support. This can be used in two ways; first, when the graphics trait requested indicates that no cursor should be present, a new cursor-less window class is used to create the window. When a cursor-enabled window creation is requested, another window class is used. After creation of a window, it is also possible to toggle the cursor state by using the GraphicsWindow::useCursor method.
* The way the mouse behaves is now compatible with the behaviour seen on X11; i.e. when pressing a mouse button, the window where the pointer is located will capture the mouse input and release it only after the button has been released. This results in all mouse movement events being dispatched to the window where the button was pressed initially until it is released. This improves the interaction with graphics windows.
* Preparation work has been done to support the ability of moving a window from one screen to another screen and recreating its rendering context when this happens. This has been tested with a mix of NVIDIA and ATI cards and works properly. For the moment being, this feature is commented out due to changes in the core OSG libraries that have been done but need to be submitted later this week for approval by Robert.
Upcoming features
* Support for moving windows from one screen to another screen seamlessly
* Ability to set the window (i.e. the application itself creates the rendering window and passes it to the GraphicsWindowWin32 class)
* Other miscellaneous items"

default Registry Options object, but it would be useful to be able to
request loading with a different Options object. The attached files
allow you to do that (based off the OSG 1.2 source).
For example, I'm implementing a loader that requires context information
when it pages in subgraphs, which becomes significantly complicated when
multiple scenegraphs are requesting subgraph loads with different
contexts (the loader needs to know which context to use, and the
Registry Options needs to be carefully managed so the context settings
don't clobber each other, especially in multithreaded situations). Being
able to pass an Options instance along with the Node request resolves
this problem."

if continuous updating is set to false.
The problem was being caused by the camera update call never being made
if continuous updating was not set to true. This fix adds a flag that
is set when dirtyOverlayTexture() is called and checked in the update
visitor section of the traversal to determine if the camera should be
updated.
I tested the fix by making some changes to the osgAnimate example
program so it has continuous updating off and calls dirtyOverlayTexture
for each frame. The overlay texture now displays properly."
"
the main problem is the wrapper generation:
The PropertyInfo class use MethodInfo class to access to the value.
When the property are define with the I_Property* macro,
the MethodInfo use by the property to have access to the value
are instancied in the I_Property* macro, but there
are already instantied by the I_Method* macro before
secondary problem:
- the function used by the property could no be customized
in the genwrapper.conf file
- an array property can't insert a value
- the std::map reflector (and indexedProperty in general) haven't remove method
- about the help in wrapper ... why not ...
solution :
To use the function define by the I_Method, I add a MethodInfo variable in the I_Method0 macro
old macro :
#define I_Method0(ret, fn) (\
params.clear(),\
addMethod(new osgIntrospection::TypedMethodIn
fo0<reflected_type, ret >(qualifyName(#fn), &reflected_type::fn, params)))
new macro :
#define I_Method0(ret, fn, signature, briefHelp, detailedHelp) \
params.clear(); \
osgIntrospection::MethodInfo* signature = addMethod(new osgIntrospection::TypedMethodInfo0<reflected_type, ret >(qualifyName(#fn), &reflected_type::fn, params, briefHelp, detailedHelp)); sink(signature)
the osgIntrospection::MethodInfo* signature is used by the I_Property macro to define the MethodInfo that it use
so for I_Property macro :
old macro :
#define I_PropertyWithReturnType(t, n, r) \
cap=addProperty(new osgIntrospection::PropertyInfo(osgIntrospection::Reflection::getType(typeid(reflected_type)), osgIntrospection::Reflection::getType(typeid(t)), #n, \
I_Method0(t, get##n), \
I_Method1(r, set##n, IN, t, value)))
new macro:
#define I_SimpleProperty(t, n, get, set) \
get, \
set))
The genwrapper has been modified in this way.
The method signature is define by the prototype of the method
For example, the "const char* libraryName();" have "__C5_char_P1__libraryName" for signature
solution for secondary problem:
The genwrapper accept new tokens in the configuration to custumize the property.
The new PropertyInserter and the CustomPropertyInsertAttribute class has been defined
The PropertyRemover has been added to the StdMapReflector
The _briefHelp and _detailedHelp variable has been added in PropertyInfo, MethodInfo and ContructorInfo class
modification:
I have modify the genwrapper files
Configuration.cpp Configuration.h add some tokens to custumize the property
Doxyfile.template add the comment in the output xml

"I've made some changes to osg which I think make it easier to control
the render order of CameraNode's. Instead of using the built-in orders
(PRE_RENDER, POST_RENDER, NESTED_RENDER), you can specify an integer
order. Values less than zero are pre rendered in order. Values greater
than zero are post rendered in order. And a value of 0 is equivalent
to NESTED_RENDER.
The changes should be fully backward compatible. Also, I changed the
RenderStageList type from a vector to a list because I needed to be
able to insert values anywhere in the list.
The reason I made these changes was because I wanted to be able to set
the render order of a CameraNode at runtime without having to reorder
it in the scenegraph."
and later in the final submission message (relating to what has been finally been merged) :

think it can be simplified quite a bit. The old code includes
<cmath> for pre-10.2 and anything using something other than g++ 4

out cmath and uses isnan(). std::isnan and cmath work for the
current version, so I just made it include cmath if __APPLE__ is
defined and removed the ifdef between versions of OS X for isnan
related things.
This way the code is all the same, and it's not fragile to someone
including <cmath> prior to including osg/Math."

I also forward declared the GDALRasterBand class in the DataSet header."
setFactorAndUnitMultipliersUsingBestGuessForDriver() static methods to
osg::PolygonOffset to help implement workarounds for lack of portablity of
settings between different hardware.
make it consistent with the constructor and prevent the
BlendFuncSeparate path being called. This patch fixed the artifact
with the osgpointsprite demo on ATI cards reported by Mike Weiblen."
"There was a typo in "int setNotifyOffset()", appear to be a getter =>
"int getNotifyOffset()".
Then I have added a switch to create GDALTermProgress only when the
current notify level + local offset permit message display. In fact, if
the offset is set to 0 and the notify level is at the default, DataSet
is quiet but for the GDALTermProgress. That is quite disturbing since
you think the progress is related to the complete processing but it is
actually only related to the GDAL Warp."
"Attached is some fixes for Image::readImageFromCurrentTexture. It was
failing when used with a new Image object (some of the fields were
not set before they were used, and some were set to the wrong values).
A new optional parameter was added to give the desired data type, which
defaults to GL_UNSIGNED_BYTE, so programs should only need a recompile
to work properly."
"attached you'll find some modifications to Producer, osgGA and
osgProducer to enable Mac OS X support for
+ scrollwheels,
+ mightymouse-srollballs
+ new tracking-pads with scroll feature
+ tablet-support (pressure, proximity and pointertype) (Wacom only tested)
I think there was a bug in the windows-implementation of scroll-wheel
support (wrong order of ScrollingMotion-enum, casting problem) which is
fixed now.
The scrollwheel-code is a bit klunky across platforms, some devices on
OS X can report an absolute delta in pixel-coordinates not only the
direction, so for now there is scrollingMotion (which describes the
direction) and scrolldeltax and scrolldeltay. I decided to leave the
scrollingmotion-stuff to not break old code relying on this."
that users can assign to it without it being overriden. If none is
assigned externally it now uses a StateSet associated wit the Font assigned
to the Text.
dded GeospatialExtents bounding box class which used doubles
in place of the original usage of osg::BoundingBox.
Added path for computing interpolation elevation data being read from GDAL.
when the binding mode changes, thereby avoiding uncessary calls to dirtyDisplayList.
Note, from Robert Osfield, moved bodies of set*Binding() into Geometry.cpp to avoid
clutter in the header.
that removeChild(Node*), removeChild(uint) and equivilant Geode methods are
now inline methods, not designed to be overriden, and seperated out the
multiple remove method to be called removeChildren(uint, uint) which is
now the only virtual method. There removeChildren is now the method to
override in subclasses.
This reorganisation requires some call code to be rename removeChild usage
to removeChildren.
osg::DisplaySettings class. OsgCameraGroup will now read the setting
from the DisplaySettings instead of hardcoding the value. I added the
following commandline option to be able to set the multisample value:
--samples <num>
One thing to note, OsgCameraGroup would previously check if the
computer is an SGI and set multisample to 4. I retained this check in
DisplaySettings to be backwards compatible."
keyboard and mouse events.
Added osgGA::EventQueue class to support a thread safe event queue and adaption
of keyboard and mouse events.
Removed osgProducer::EventAdapter as GUIEventAdapter replaces it.
Adapted osgProducer and examples to work with the new changes to osgGA.
an invalid bounding sphere if it hasn't seen a cull traversal yet. It
depends on _firstTimeToSetEyePoint, which is initially true, then false
after a cull. There might be a better way? If so, let me know.
This change does resolve the issue I had encountered with auto scale to
screen and incorrect culling."
