Thanks to Vivian Meazza for debugging this. The output deque for
FGDigitalFilter was not being kept long enough for the
doubleExponential filter. Reads from output[1] could cause a crash.
From Till:
i started the project at the end of february with a simple idea: move all
3d-model loading to the DatabasePager-thread. my first attempts looked
promising, though they were a little too optimistic (or naive?). the patch
has evolved a lot since.
currently it does the following things:
1. revive SGModelLib, move functions for xml-model-loading there
2. replace all calls to sgLoad3dModel with calls to either
SGModelLib::loadModel() or SGModelLib::loadPagedModel()
almost all models will be loaded by the DatabasePager. the few exceptions are:
your own plane, shared models in scenery, random objects, AIBallistic models.
3. simplify mode-loading functions (avoid passing around fg_root)
4. avoid supurious MatrixTransform nodes in loaded models
5. fix some memory leaks
Introduce a convenience member function in wxRadarBg for creating an
SGPropertyNode and initializing it in one step. Use this in
agRadar. This eliminates buggy behavior when the necessary radar
properties aren't defined.
version
* Delete ai list objects in ~ATC/AIMgr.cxx:AIMgr::~AIMgr()
* Delete colors in GUI/new_gui.cxx: NewGui::~NewGui.cxx
* Delete memory allocated to the class member "route" in
Instrumentation/gps.cxx
* Delete all globals (except a few "unsafe" ones that still cause segfaults
and need further examination.
* Use an SGShared pointer for navaid memory allocation, so that pointers to
individual navaid objects can be included safely in multiple navaid lists
the next airport or airport with METAR station, but about any type of
airport
- as a side effect this change makes it also 30 to 50% faster :-)
In the long run this linear search shall be replaced with a spatial
algorithm (like octree), which will be a much bigger performance gain.
Turn OPENSCENEGRAPH_MAJOR_VERSION, OPENSCENEGRAPH_MINOR_VERSION and
OPENSCENEGRAPH_PATCH_VERSION into a single number for comparisons in the
preprocessor.
together -- there's only *one* instrument node now
- don't take "random" tacan, but <tacan-source> from the instrumentation
config (or /instrumentation/tacan[0] by default)
- don't take "random" display-controls from /instrumentation/tacan[0]
- default name is now "radar" (formerly "wxradar")
- re-enable od_gauge ("owner drawn" render-to-texture instruments)
- implement radar in c++ (unlimited number of clouds/ai/mp/... objects,
better performance)
a second tacan may not be likely)
- remove some dead code
- simplify <name>/<number> handling
- let a listener watch over input props and search for new channel/frequency
- allow to set channel number as one number (rather than as single digits),
as some aircraft may prefer this (the ch53 does so); this is to be set
in /instrumentation/tacan[n]/frequencies/selected-channel[0]
