Added DRAW command dsetsignal, resetting OSD signal handler with either armed or disabled FPE handler, according to an option.
If called without arguments, it sets FPE handler only if environment variable OSD_FPE is defined (with value different from 0).
On start, DRAW calls dsetsignal to set FPE signal if CSF_FPE is defined.
Test bugs fclasses bug6143 uses dsetsignal to set FPE handler unconditionally before the test command, and resets it to default at the end.
A number of changes in the code have been done in order to fix floating point exceptions that became generated after enabling signals:
- Global functions Sinh() and Cosh() defined in Standard_Real.hxx are improved to raise Standard_NumericError exception if argument is too big (greater than 710.47586), instead of relying on system treatment of floating point overflow. These functions are used instead of sinh and cosh in ElCLib.cxx.
- Maximal value of parameter on hyperbola is restricted by 23 (corresponding to ~1e10 in 3d) in order to avoid FP overflow in Extrema_GenExtCS.cxx, ShapeFix_EdgeProjAux.cxx.
- Interface of the root curve adaptor class Adaptor3d_Curve has been updated to add new virtual methods BasisCurve and OffsetValue. They complement the adaptor for the case of offset curves. These methods are used in Extrema_GenExtCS.cxx to restrict domain search in the case of offset of hyperbola, in order to get rid of floating point overflow. All classes inheriting Adaptor3d_Curve have been changed to implement the new virtual methods.
- Protection against division by zero has been implemented in ApproxInt_KnotTools.cxx, BRepClass3d_SClassifier.cxx, BRepGProp_Face.cxx, BRepMesh_FastDiscretFace.cxx, Geom2dGcc_Circ2d2TanOnIter.cxx, Geom2dInt_Geom2dCurveTool.cxx, IntPolyh_MaillageAffinage.cxx.
- Protection against calling of math functions of infinite arguments has been added in BRepCheck_Edge.cxx, BRepLib.cxx, CSLib_NormalPolyDef.cxx, Extrema_FuncExtPC.gxx, Extrema_GExtPC.gxx, Extrema_GLocateExtPC.gxx, Intf_InterferencePolygonPolyhedron.gxx, ShapeAnalysis_Surface.cxx, ShapeAnalysis_TransferParametersProj.cxx, ShapeAnalysis_Wire.cxx, math_FunctionSetRoot.cxx.
- Proper initialization of local variables is done in BOPAlgo_PaveFiller_6.cxx, XSDRAWSTLVRML.cxx.
- Inconsistent usage of Standard_Boolean* to access integer data in HLR (caused by #27772) is corrected
Some test cases have been updated to actual state.
The matter was that during checking wires of a shape for small area, non-outer wires were checked with constructing a new face with BRepBuilderAPI_MakeFace. If a face has location an edge from original face has no pcurve on the constructed face, which leads to exception in BRepGProp::SurfaceProperties. The fix constructs new face using EmptyCopy.
The method ShapeAnalysis_Wire::CheckSmallArea() has been changed so as to check area of the outer wire without hole-wires. API of this method has been changed, as the second argument theIsOuterWire is not needed any more.
The test cases have been updated, below are explanations of changes:
test de iges_2 G7
The fixed version leaves a wire in a face, but the master version considered it small and removed. The master version works wrong. It is because the face built with this wire has negative area, but the code in CheckSmallArea function does not get absolute value before comparing area with the tolerance. The left wire leads to splitting of the face on two, checkshape error in the face, and statshape faulty due to increased number of faces in the second pass.
test de iges_2 G2
The fixed version leaves a wire that is removed in the master version. The cause is the same as in G7 test case. However, here the problematic wire has very big tolerance. So, when the fixed version left it in the shape, the overall maximal tolerance became much greater than in reference data.
test de step_3 E6
In fixed version a really bad small wire is removed from the face, while in master version it is left and produces an error in checkshape report. So, it is an improvement.
Code has been updated to remove no-op casts and implicit casts to Standard_Boolean.
Places of inproper use of Standard_Boolean instead of Standard_Integer
have been corrected:
- Bnd_Box, Bnd_Box2d
Bit flags are now defined as private enum
- HLRAlgo_BiPoint, HLRAlgo_EdgesBlock, HLRBRep_EdgeData, HLRBRep_FaceData
Bit flags are now defined as enum
- HLRAlgo_EdgeStatus, HLRBRep_BiPnt2D, HLRBRep_BiPoint
Bit flags are now defined as bool fields
- HLRAlgo_PolyData
Bit flags are now defined as Standard_Integer
- OSD_DirectoryIterator, OSD_FileIterator
Boolean flag is now defined as Standard_Boolean
- ShapeAnalysis_Surface::SurfaceNewton()
now returns Standard_Integer (values 0, 1 or 3)
- ChFi2d_FilletAlgo
now uses TColStd_SequenceOfBoolean instead of TColStd_SequenceOfInteger
for storing boolean flags
Method IFSelect_Dispatch::PacketsCount() has been dropped from interface.
ShapeFix_Solid::Status() has been fixed to decode requested status
instead of returning integer value.
TopOpeBRepBuild_Builder1 now defines map storing Standard_Boolean values
instead of Standard_Integer.
Persistence for Standard_Boolean type has been corrected
to keep backward compatibility:
- BinMDataStd, BinTools, FSD_BinaryFile
Broken Draw Harness commands vdisplaymode and verasemode have been removed.
BRepMesh_FastDiscretFace::initDataStructure() - workaround old gcc limitations
BRepMesh_IncrementalMesh::clear() - avoid ambiguity
Method DownCast() is made template, to be available only when argument is actually a pointer or handle to a base class.
For compatibility with existing code, method DownCast() that can be used for the same type, derived, or unrelated class (i.e. where there is no actual down casting) is still available, its use shall cause "deprecated" compiler warning.
OCCT code is updated to remove meaningless DownCast()s; a few places where DownCast() was used with argument of unrelated type are corrected.
DRAW command QAHandleCast is removed (it was useful only during redesign of handles).
Add checks to avoid exceptions.
Remove check for small 3D curve, now pcurve will be built for all small edges, which have not been removed by FixSmall.
Context usage extended in method ShapeFix_Wire::FixSelfIntersection() to avoid modification of original shape by shape healing.
Added check for subshape modification in XSAlgo/XSAlgo_AlgoContainer::MergeTransferInfo().
Test cases are updated to the new behaviour.
Test case for issue CR24658
Added missing Standard_EXPORT for public methods; declaration of unimplemented method removed.
Restoring some changes made for #26788 but omitted in its commit.
OpenGl_View::ReadDepths() - drop obsolete and broken method; V3d_View::ToPixMap() should be used instead
Added set of methods CopyVertex in BRepTools_ReShape. Usage of this non-modifying methods added in ShapeFix_Wire, ShapeFix_Edge.
Test case for issue 26656.
Test cases updated to the new behavior.

Corrected test case
A new script adm/upgrade.tcl defines a Tcl procedure occt_upgrade, to be used for upgrading code of OCCT and applications for changes introduced by OCCT 7.0.
Batch script upgrade.bat is provided for convenience.
File upgrade.dat contains data (lists of classes) required for some upgrade steps.
Details on upgrade procedure are put in dox/dev_guides/upgrade/upgrade.md.
OCCT code corrected to improve compatibility with code based on previous versions of OCCT:
- Added conversion operator of handle to bool, for use in conditional expressions.
- Forward declaration of argument class restored in macro DEFINE_STANDARD_HANDLE.
- Includes of used classes added in some headers to avoid problem of missing includes in dependent code
- Type cast operators to base curve and surface added in GC and GCE2d classes to reduce porting issues.
Added test for local reference to handle initialized by temporary handle to derived class.
WOK and CDL User Guides removed.
Attached invalid shape is represented by solid containing one face twice.
Protection from such case was added in ShapeFix_Shell class.
Creation of COMPSOLID was modified for case when shells composing COMPSOLID have the same shared faces in order to prevent hanging.
Small modification.Protection to avoid exception
Test-case for issue #26408
Test commands for checking performance and functionality of OCCT handles and RTTI added.
New test case added for that: test perf fclasses handle.
Implementation of opencascade::handle improved to enable compile-time error if two handles of incompatible types are compared.
Comparison of handle to NULL is not possible any more; method IsNull() should be used instead.
Method LDOM_MemManager::Doc() is removed to avoid cyclic dependency of headers; constructor of LDOM_Document(LDOM_MemManager&) is used directly instead.
Inclusion of headers corrected for compilation after previous patch.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
Missing headers added; includes of headers "Handle_...hxx" removed.
Misuses of macro Handle() and its use in typedefs corrected.
Alias classes Profile and Option are removed from IFSelect; ones defined in MoniTool are used directly.
Removed header files defining only Handle classes (except Image_PixMap_Handle.hxx)
Classes SelectMgr_BaseFrustum and now inherit Standard_Transient and can be manipulated by Handle (not NCollection_Handle)
Fixed reference-type local variable pointing to temporary object
Use of handle in conditional expressions and comparisons to NULL are replaced by call to method IsNull()
Forward declaration of TCollection instances as classes are replaced by inclusion of corresponding header.
Cyclic dependencies between declaration of collection class and its item are resolved by forward declaring a class in collection header.
A tool to remove tails from the wires of a shape was created.
The tool is based on mechanism 'ShapeFix',
is located in types 'ShapeFix_Wire' and 'ShapeAnalysis_Wire',
is enabled through method 'ShapeFix_Wire::FixTailMode' and
is initialized by methods 'ShapeFix_Wire::SetMaxTailAngle' and 'ShapeFix_Wire::SetMaxTailWidth' and
is called through method 'ShapeFix_Wire::FixTails'.
The status of any performing of the last method is accessible through method 'ShapeFix_Wire::StatusFixTails'.
The tail angle is checked only at the tail start.
Mechanism 'ShapeFix' was modified:
- the tool is disabled by default;
- algorithm 'Fix notched edges' is disabled then the tool is enabled;
- the tool and the last algorithm work in turns then the tool works on the request.
'Draw' command 'fixshape' was extended by options '-maxtaila' and '-maxtailw' to test the tool.
'Draw' tests to test the tool were created.
Algorithm 'fixshape' was changed in type 'ShapeProcess_OperLibrary' to
- use new parameters named 'FixTailMode', 'MaxTailAngle' (in degrees) and 'MaxTailWidth' from the algorithm context;
- apply the tool after the shape will be fully fixed if the tool was enabled.
Place holders for the new parameters were created in the resource file of mechsnism 'STEPControl_Reader'.
Test cases for issue CR26261
1. B-spline cache was moved into separated classes: BSplCLib_Cache for 2D and 3D curves and BSplSLib_Cache for surfaces.
2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.
3. Algorithms were changed to use adaptors for B-spline calculations instead of curves or surfaces.
4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)
5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.
6. Test cases were modified according to the modern behavior.
7. Changes in BOPAlgo_WireSplitter, BOPTools_AlgoTools, BRepLib_CheckCurveOnSurface and ShapeAnalysis_Wire to use adaptors instead of geometric entities
8. Allow Geom2dAdaptor and GeomAdaptor in case of offset curve to use corresponding adaptor for basis curve
Modification of test-cases according to the new behavior.
The analysis of small area in the method ShapeAnalysis_Wire::CheckSmallArea is performed the following way:
- On the fisrt step algorithm produces a rough estimation of part of surface area.
- In a case if obtained estimation is less than tolerance then evaluate real area and comapre this value with tolerance.
- New flag has been added to XSTEPResource/IGES. In a case if flag is true the faces with small 3d area is removed from ShapeFix context.
Test-case for issue #25923 and update test-cases in de group according to the new behavior.
Recalculate of tolerance before edge cutting
Test case for issue CR25013
add try to increase tolerance before splitting in singularity during PCurve adding.
Correction of test cases for issue CR25013
The number of points to divide the edge curve on a segments to compute a
boundary box does not provide a good tolerance. So a resultant boundary
box has an incorrect bounds. As a result the intersection near to a
tangent of curve does not detected.
Test case for issue CR25823
The reason of FAIL status of FixGaps3d is that the trying to convert
curves to BSplines on valid edges (both adjacent points saticfy a
precision) leads to skipping of the convertation and gives wrong status.
Check of the gap on adjacent points before try ro convert curves was added.
Test-case for issue #24881
Check whether p-curve being projected can be approximated by straight line is made before full-scale projection, to improve performance.
If straight, pcurve is created as Line only if this will lead to the same range parameterization as 3d curve, otherwise BSpline of degree 1 is created.
Re-approximation of line pcurves by bsplines removed from ShapeFix_Edge.
Test case updating to new behavior.
Added "static" keyword to the fixPeriodictyTroubles() function.
Update of test-cases according new behavior
1. Using of the "Closed" flag was unified:
a) this flag is applicable for TopoDS_Wire and TopoDS_Shell only, because these entities may hedge an area in 2D space or a volume in 3D space correspondingly;
b) other types of TopoDS shapes are passing over this flag;
c) changing of this flag should be controlled by high-level algorithms (not BRep_Builder).
2. Implemented verification of the closedness of edges. An edge is closed if and only if its first and last vertices are the same.
3. Test cases were changed according to new behavior.
Messages are registered in ShapeExtend_MsgRegistrator added to ShapeCutom and ShapeUpgrade packages

0025520: To provide info on what has been done by Shape Process and Shape Fix
Update SHAPE.fr
Fix some messages (minor change)
Added check and fix of tolerances of all vertices after performing all fixes.
It is necessary to avoid situation when point of vertex belonging a few faces was changed for current face
but edges containing this vertex belonging before fixed face are not taking into account.
Mode FixVertexTolMode to manage check tolerance of vertices was added in ShapeFix_Shape
class. (default value is equal to -1)
Method to change FixVertexTolMode mode FixVertexTolMode() was added in ShapeFix_Shape class
Test case for CR25455
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
