ea86bfe2fa Testing - Removing direct DCAF loading #147
DCAF require VISUALIZATION for correct work.
  In some scenario DRAWEXE can generate a dublicates of the
  internal static singletons. This means each dynamic library
  will have their own instance of the static singleton.
Update all direct library loading to use the DCAF plugin
  mechanism. This will ensure that the DCAF plugin is loaded
  only once and that the correct instance is used.
Originally issue is reproduced only Linux with dlopen with "RTLD_LAZY".
Can be resolved additionally adding "RTLD_LAZY | RTLD_GLOBAL" for dlopen

7bd071edb1 0026106: BRepMesh - revision of data model
Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.

The workflow of updated component can be divided on six parts:
* Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
* Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;
* Heal discrete model: source TopoDS_Shape can contain problems, such as open-wire or self-intersections, introduced during design, exchange or modification of model. In addition, some problems like self-intersections can be introduced by roughly discretized edges. This stage is responsible for analysis of discrete model in order to detect and repair faced problems or refuse model’s part for further processing in case if problem cannot be solved;
* Preprocess discrete model: defines actions specific for implemented approach to be performed before meshing of faces. By default, iterates over model faces and checks consistency of existing triangulations. Cleans topological faces and its adjacent edges from polygonal data in case of inconsistency or marks face of discrete model as not required for computation;
* Discretize faces: represents core part performing mesh generation for particular face based on 2D discrete data related to processing face. Caches polygonal data associated with face’s edges in data model for further processing and stores generated mesh to TopoDS_Face;
* Postprocess discrete model: defines actions specific for implemented approach to be performed after meshing of faces. By default, stores polygonal data obtained on previous stage to TopoDS_Edge objects of source model.

Component is now spread over IMeshData, IMeshTools, BRepMeshData and BRepMesh units.

<!break>

1. Extend "tricheck" DRAW-command in order to find degenerated triangles.

2. Class BRepMesh_FastDiscret::Parameters has been declared as deprecated.

3. NURBS range splitter: do not split intervals without necessity. Intervals are split only in case if it is impossible to compute normals directly on intervals.

4. Default value of IMeshTools_Parameters::MinSize has been changed. New value is equal to 0.1*Deflection.

5. Correction of test scripts:

1) perf mesh bug27119: requested deflection is increased from 1e-6 to 1e-5 to keep reasonable performance (but still reproducing original issue)
2) bugs mesh bug26692_1, 2: make snapshot of triangulation instead of wireframe (irrelevant)

- Exception on VOID bounding box is avoided.
- Arguments are handled in case-insensitive way.
- Options -s, -perfmeter, and ability to set result as first argument are removed as redundant.
- Help is moved to command definition.

Separate command OCC29311 is added (in QADraw) to do the same as option -perfmeter did; tests are updated.

4f7d41eac3 0029604: Uniform mechanism providing History of shape's modifications for OCCT algorithms in DRAW
Implementation of the mechanism for unification of the history commands for all OCCT algorithms.
The following Draw commands should be used to track the history of shapes modifications of any operation:
- modified - to find the shapes modified from the given shape in the given history.
- generated - to find the shapes generated from the given shape in the given history.
- isdeleted - to check if the given shape has been deleted during operation.

The mechanism allows fast & easy enabling of the DRAW history support for the algorithms supporting the history on the API level (i.e. the algorithm should have the methods Modified(), Generated() and IsDeleted()).
To enable the draw history support it is necessary to store the history of the algorithm into the session. For instance:

TopTools_ListOfShape Objects = ...; // Objects
TopTools_ListOfShape Tools = ...; // Tools

BRepAlgoAPI_Cut aCut(Objects, Tools); // Boolean cut operation

BRepTest_Objects::SetHistory(Objects, aCut); // Store the history for the Objects (overwrites the history in the session)
BRepTest_Objects::AddHistory(Tools, aCut);   // Add the history for the Tools

To get the stored history in draw the command "savehistory" should be used. It saves the history kept in session into a Drawable object with the given name:

# perform cut
bcut r s1 s2

# save history of cut
savehistory cut_history

explode s1 f
modified m cut_history s1_1

The Draw History commands of the following algorithms have been removed:
- Boolean Operations;
- Defeaturing;
- Unify same domain;
- Sweep;
- Thrusections;

All these algorithms have been switched to support the new Draw history mechanism.

The Fillet and Blend algorithms have been also enabled to support history commands.

33ba856502 0028786: Refactoring of the Warning/Error reporting system of Boolean Operations Algorithm
0. Basic tools for defining classes representing alerts (errors, warnings etc.) and collecting them during execution of algorithms are added in Message package.

1. Refactoring of the Error/Warning reporting system of the algorithms in Boolean Component.
   To dump the description of the Error/Warning status of the algorithm the DumpErrors/DumpWarnings method should be called.
   Also, the methods GerErrorMsg(int Error) and GetWarningMsg(int Warning) have been implemented to get the description for the given Error/Warning.
   All Error/Warning statuses are now listed in the enumeration ErrorStatusEnum/WarningStatusEnum of the algorithm.
   It is also possible to get the shapes for which the warning has been set by using the method GetWarningShapes().

2. The new class BOPAlgo_Options has been created to unify the options of the BOPAlgo_* and BRepAlgoAPI* algorithms.

3. The new checks across the algorithms have been added to detect and report errors and warnings.

4. Test cases
  boolean bopcut_complex B9 E1 E5 E8
  boolean bopfuse_complex B4 B5 C9 D1 D4 D5 D6 D7
have been rewritten to use Cells Builder algorithm instead of Boolean Operations algorithm, because latter always returns error "Unsupported Boolean operation" for these cases.

5. New chapter has been added in the user guide for Boolean Operations - Error / Warning reporting system.

0d0481c787 0026738: Make Boolean operations safely treating arguments when running with fuzzy option
When fuzzy option is in force prevent increasing tolerance of input shapes. Instead pass increased by fuzzy value the tolerances of sub-shapes everywhere where it is needed by intersection algorithms.

The following changes in API have been made:

- The methods SetFuzzyValue and FuzzyValue have been moved from the classes BOPAlgo_ArgumentAnalyzer, BOPAlgo_Builder, and BOPAlgo_PaveFiller to the base class BOPAlgo_Algo.
- The public method BOPDS_DS::VerticesOnIn has been renamed to SubShapesOnIn, and the new output parameter theCommonPB has been added.
- In BOPTools_AlgoTools, a new argument "theFuzzyValue" has been added in the methods ComputeVV and AreFacesSameDomain.
- In IntTools_Context, a new argument "theFuzzyValue" has been added in the methods ComputeVE and ComputeVF.
- The methods SetFuzzyValue and FuzzyValue have been added in the classes IntTools_EdgeEdge, IntTools_FaceFace.
- In the class IntTools_EdgeFace, the methods SetTolE, SetTolF, TolE, TolF have been removed, and the methods SetFuzzyValue, FuzzyValue have been added.
- The new argument "theTol" has been added in the method IntTools_WLineTool::DecompositionOfWLine.

Some improvements in algorithms have been made during fighting with regressions:

- Correct initialization of pave blocks for degenerated edges.
- In BOPAlgo_PaveFiller::MakeBlocks(), filter out paves on intersection curve that were put on the curve accidentally due to wide range of E-F intersection vertex.
- In the method IntTools_Tools::ComputeTolerance the margin added to the computed tolerance has been increased up to 0.001%.
- The method BOPAlgo_PaveFiller::PutPaveOnCurve has been corrected in order to use the original vertex tolerance instead of the value increased during putting it on other curves.
- The new method BOPDS_PaveBlock::RemoveExtPave has been added.
- The vertex tolerance computation in BOPTools_AlgoTools::CorrectCurveOnSurface has been improved, taking into account intersection segments between p-curves (to avoid regression on "bugs modalg_6 bug22794").
- Improve IsExistingPaveBlock to make more stable catching of coincidence of common block with section curve (against regression "bugs modalg_4 bug697_2" on Linux).

Test case for the bug has been added.

The following test cases have been updated as improvements:
boolean gdml_private ZH2 ZI7 ZJ7
boolean volumemaker C4

The test case bugs/modalg_4/pro19653 has been corrected to make it stable. See comment inside the script for details.

The test case bugs/modalg_6/bug25880 has been corrected to suppress wrong bfuse commands.

The test bugs/modalg_6/bug26954_3 has been corrected to compare the result with more precise reference value.

The "faulty" TODO in boolean/volumemaker/A8 has been made actual for Linux as well.

e2e0498b17 0027431: [Regression to 6.9.1] Huge tolerance obtained during intersection of cylinder and sphere
The root of the problem is incorrect processing of cases when intersection line goes through the apex(es) of sphere. The fix improves this situation. The algorithm is taken from DecomposeResult(...) function (see IntPatch_ImpPrmIntersection.cxx file). Before the fix, faltering steps were done to solve this problem. As result, it worked in some particular cases. Now, its possibilities have been extended significantly.

Following changes have been made in the fix:

1. Class IntPatch_ALineToWLine has been rewritten cardinally. It touches as interfaces of existing methods as adding/removing some methods/fields. Correction touches both cases: going through seam of Cone/Sphere and through pole(s) of sphere. Old interface did not allow making some actions with analytical line (ALine), e.g. splitting it on several Walking-lines (WLine).

2. Restriction-line support has been removed from Implicit-Implicit intersection result (see IntPatch_Intersection::GeomGeomPerfom(...) method). It connects with the fact that the intersection algorithm itself returns precise intersection line in analytical cases (in compare with parametric intersector). Therefore, we do not need in additional (restriction) line.

3. New class IntPatch_SpecialPoints has been added. This class contains methods to add some special points (such as apex of cone, pole of sphere, point on surface boundary etc.) in intersection line (IntPatch_PointLine). It is based on the static functions, which already exist in IntPatch_ImpPrmIntersection.cxx file (these functions have been moved to the new class).

4. Method IntPatch_WLineTool::ExtendTwoWlinesToEachOther(...) has been renamed to IntPatch_WLineTool::ExtendTwoWLines(...). It is connected with changing main idea of the method. Now it allows extending WLine to the surface boundary or to the singular point (if it is possible): cone apex, sphere pole etc. Interface of this method has been corrected, too. At that, old functionality (extending to each other) has been kept. For implementation of this algorithm, new enumeration "IntPatchWT_WLsConnectionType" has been created.

5. Method IntPatch_PointLine::CurvatureRadiusOfIntersLine(...) has been added. See IntPatch_PointLine.hxx for detail information. It allows correct step computing depended on the local curvature of the intersection line. This method uses geometrical properties of intersected surfaces to compute local curvature. Therefore, it can be applied in wide range of cases even if the intersection curve is not represented in explicit form (e.g. in case of param-param-intersection).

6. Method IntSurf::SetPeriod(...) has been created.

7. Additional check has been added in Draft_Modification::Perform() method for better choice of correct fragment of intersection line for processing DRAFT operation.

8. New overload method IntPatch_Point::SetValue() has been added.

9. Some refactoring of the code has been made.

Creation of test case for issue #27431.

---------------------------------------------------------------------------------------------
Some test cases have been adjusted according to their new behavior.

   tests\bugs\modalg_4\bug62
It is really IMPROVEMENT (but fortuitous).

   tests\bugs\modalg_5\bug25838
The behavior of this test has been reverted to the state before fixing the issue #27341. Main problem has not been fixed in #27341. It was fortuitous improvement.

    tests\bugs\moddata_2\bug565
Quality of intersection curve was not checked. And the curve is bad on both MASTER and FIX. Input data are really wrong: plane-like-cone. However, on the MASTER, four intersection curves (the quality is insignificant) are expected. On the fix, not empty intersection result is expected simply.

   tests\boolean\volumemaker\A8
Differences in images and CPU is expected. Difference in images is expected to be fixed in the issue #26020. Now, we should apply this behavior.
Much CPU time is spent by IntTools_FaceFace::ComputeTolReached3d(...) and GeomInt_IntSS::BuildPCurves(...) methods calling. These methods are not touched by the algorithm. It is the result of change of intersection curve(s) form. However, the new Curve(s) seems to be valid and can be applied. As result, new behavior can be applied, too.

   tests\boolean\volumemaker\F8
   tests\boolean\volumemaker\F9
   tests\boolean\volumemaker\G5
   tests\boolean\volumemaker\G6
CPU difference is expected. Much CPU time is spent by IntPatch_PointLine::CurvatureRadiusOfIntersLine(...) method calling. This method is really new (it does not exist on the MASTER) and is really useful. Therefore, we should apply new behavior.

   tests\boolean\volumemaker\G1
CPU difference is expected. Much CPU time is spent by IntTools_WLineTool::DecompositionOfWLine(...) and IntTools_FaceFace::ComputeTolReached3d(...) methods calling. These methods are not touched by the algorithm. It is the result of change of intersection curve(s) form. However, the new Curve(s) seems to be valid and can be applied. As result, new behavior can be applied, too.

   tests\bugs\modalg_6\bug26619
Differences in images is expected. The test keeps its BAD status on the FIX. But the result on the fix is nearer to expected than on the MASTER. Issue #27014 is still actual. As before, it is not clear, why the number of entities is different. The number of section curves has not been changed. Interfered entities are the same as on the MASTER.

   tests\bugs\modalg_5\bug25319_1(2)
The reason is described in the issue #27896.

93e38faa3b 0027179: The algorithm of sharing edges in Boolean operation should be improved
1. New sharing algorithm has been implemented. If intermediate point of some edge is included in the tube with center taken in another edge and radius equaled to maximal vertex-tolerance of both edges then these two edges are considered to be shared. This know-how touches edges only, which have common blocks with interfered faces. If they do not have any common-blocks the algorithm will work as before.

2. Interface of BOPAlgo_PaveFiller::IsExistingPaveBlock(...) method has been changed.

Creation of test case for issues #27128 and #27179

a09c8f3aa5 0027190: IntPatch_ImpPrmIntersection algorithm does not split intersection curve by the seam-edge of the quadric
1. Processing when IntPatch_WLine/IntPatch_RLine goes through the seam edge has been improved in DecomposeResult(...) function (see IntPatch_ImpPrmIntersection.cxx).
2. Incorrect initialization of last point of IntPatch_WLine/IntPatch_RLine has been eliminated. Earlier it was the reason of exception.

Creation of test case for this issue.

Adjusting some test cases according to their new behavior. Namely:

1) tests\bugs\modalg_4\bug825 (bug825_2)
Details are described in issue #25915. In short, new intersection algorithm works better than old (WLine without "jumping"). However, Boolean operation loses degenerated edges of the sphere. Consequently, we get the result with Not-closed face.

2) tests\bugs\modalg_6\bug26684_2
TolReached of intersection curve has become smaller. Consequently, intersection algorithm works better than earlier.

3510db6201 0026619: Tolerances of operands are modified using bop
0026796: The result of General Fuse operation is self-intersecting shape

The fix forces creation of new sub-shapes (vertex, edge) when the tolerance of some sub-shape of an argument is to be increased.

This new behavior is turned off by default. It can be turned on using two ways:
1) Setting 'locking' flag of the arguments.
2) Calling the method SetNonDestructive(Standard_True) of the API classes.

Various bug fixes in the algorithm:
- Compute correct tolerance values for intersections of type Line/Line, Line/Plane, Plane/Plane.
- In case of Line/Plane intersection check if line's vertices lie on the plane.
- Do not allow decreasing of the tolerance value of the Line/Line intersection vertex.
- In IntTools_EdgeEdge, call the method FindParameters with proper 3D tolerance of the curve.
- Force making copy of a degenerated edge if its vertex is touched but no 2D intersection with other curves is found.
- Remove pave blocks both ends of which became referring to the same vertex after vertices substitution.
- Avoid exception in IntTools_Context::IsVertexOnLine if Extrema is not done.
- Reduce tolerance of vertex/edge using actual distances to interfered shapes if it was increased due to line/line, line/plane, or plane/plane small intersection angle.
- Update tolerance of edges to reach all representations in a common block.
- In V-E intersections, check if a vertex hits beyond shrunk range, in such case create V-V interference.
- Do not put a section edge to the result if it becomes to be a micro edge after updating its vertex.
- Correctly make vertices same-domain during the work of MakeBlocks.
- Decrease shrunk range at least on a Precision::Confusion() in addition to vertex tolerance.
- Add Confusion to bounding boxes of new shapes in DS
- Add tolerance Precision::Confusion() to compare distances of touching cases to fix regressions.

6d3685029f 0026622: Tests - Avoid using dlog and decho commands in test scripts
Added possibility to define patterns that must be present in the test log, so that test is considered OK only if all these patterns are found.
New REQUIRED statement is introduced for that, documented in dox/dev_guides/tests/tests.md.

Removed all uses of decho and dlog commands, added REQUIRED where necessary.
Command xdistcs is modified to output to Tcl instead of cout, and extended to report errors and warnings if distances are greater than tolerance (directly, instead of complex post-processing on Tcl level).

DEBUG mode for TODOs was removed (we should have no deviations in Debug mode).
