Debug code enabled with OCCT_DEBUG macro corrected for compiling with new handles.
QANCollection_Handle.cxx simplified so as to avoid need of using /bigobj option when building by Visual Studio; templates of project files, CMake projects, and test perf fclasses handle corrected accordingly.
Script genproj corrected to recognize VTK and to build DRAWEXE as executable (rather than DLL).
0022827: Make non-CPP source files (CDLs, headers) to appear in MS VS project files -- documentation
Generation of OCCT overview documentation added as building of "Overview" project.
BUILD_OCCT_OVERVIEW variable introduced to offer generation OCCT overview documentation in html format.
Overview md files added to overview OCCT project.
"Building with CMake" article updated; overview.html copy into an install directory.
CMAKE_BUILD_TYPE for single-configuration generators described; BUILD_CONFIGURATION removed.
0024786: Move functionality of WOK command wgenproj to OCCT tool genproj
WOK scripts used in generation of MSVC projects are put to adm/genproj.tcl
Batch script genproj.bat added, replacing 'wgenproj' command of WOK.
WOK tool for configuring custom.bat is also copied; it is called by genproj if custom.bat does not exist
Environment variable SHORTCUT_HEADERS can be defined in custom.bat to have headers put in inc just shortcuts to actual headers, instead of copies.
Corresponding option "copy OCCT short-cut headers instead of original one to inc folder" is added to genconf dialog
0026389: The Visual Studio solution of OCCT generated by CMake should have all build configurations
the choice of OCCT build type moved to generated projects
debug library search removed from 3rdparty search mechanism
draw.bat receive 3 arguments: compiler, bitness and build type
0026388: Setting debugging environment of the Visual Studio solution of OCCT generated by CMake
0. debugging environment added to DRAWEXE vcxproj
1. OCCT header files copied to inc directory of an installation folder. (the grouping of header files removed)
1. collect reference files of all OCCT header files in <binary dir>/inc during cmake configuration process
2. tcl installation procedure installs all dlls found in tcl bin folder (for win. this approach takes into account installing of zlib library that may be located in tcl bin folder)
4. each a OCCT project include just 3rdparty paths and <cmake binary dir>/inc folder
Adaptations for compiling with GCC 4.7 and 4.8:
- Construction semantics is used for Handle objects being initialized by const Handle objects of derived type, to avoid overload resolution error in GCC 4.7.
- Missing includes added.
- Fixed bugs related to misuse of direct casts of handle.
- Eliminate CLang warnings on uninitialized and unused variables, functions, and expressions
StepToGeom package refactored to avoid C-style casts of handles to derived types.
Instead of 45 classes, each defining single static method, it now defines 45 static methods in the main package class.
Results of conversion are returned in normal way rather than via function parameter.
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.
0024002: Overall code and build procedure refactoring -- manual
Documentation comments (mostly to package items, in package CDL) lost by CDL extraction are transferred to headers manually.
Some wrong comments (artifacts of CDL-generated code) are removed.
Missing header files added.
Yacc and Lex files removed from StepFile/FILES to avoid problems when building by WOK
0024002: Overall code and build procedure refactoring -- automatic
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
Code corrected to avoid ambiguous situations due to changed implementation of Handle (overloaded methods accepting handles of different types).
In Adaptor3d_CurveOnSurface added method Load() with two parameters, allowing to avoid ambiguity of cast of handles when calling separate methods Load() for curve and surface, replacing by single call.
In DrawTrSurf and IGESData_IGESWriter, template variants of methods Set() and Send(), respectively, are added to avoid ambiguity when these methods are called with handles to derived types (using SFINAE).
In NCollection_DefineHSequence, method Append() accepting handle to another HSequence is made template, to be available only if argument has compatible type.
0024023: Revamp the OCCT Handle -- downcast (automatic)
Automatic update by command "occt_upgrade . -downcast"
C-style cast of Handle to that of derived type (now illegal) is replaced by call to DownCast()
Const reference local variables of Handle type initialized by result of DownCast are replaced by normal variables.
Definition of PLUGINFACTORY function changed to return Standard_Transient* instead of Handle(Standard_Transient), which cannot be returned by C-style function.
Default implementation of PLUGINFACTORY() instantiated by macro PLUGIN() is corrected accordingly.
Methods Factory() in persistence packages are made returning const & to handle; this is to reflect the fact that returned handle should point to existing object (usually statically allocated) rather than new one.
Macro defining Handle class is replaced by template class implementing the same concept (defined in Standard_Handle.hxx and Standard_Transient.hxx), opencascade::handle<>.
Header file Standard_DefineHandle.hxx becomes deprecated: the only useful macro DEFINE_STANDARD_RTTI is defined now in Standard_Type.hxx. Standard_DefineHandle.hxx is kept for compatibility, it defines macros previously used for definition of Handles and RTTI as empty. Macro DEFINE_STANDARD_HANDLE(C1,C2) is also kept for compatibility; now it expands to typedef "Handle_C1" to corresponding handle class.
Definitions of macro Handle() and STANDARD_TYPE() moved from Standard_Macro.hxx to Standard_Handle.hxx (new file) and Standard_Type.hxx, respectively.
New template class NCollection_Shared added, allowing to define sub-class manipulated by handle, for any non-transient class.
Package SortTools and its derived classes are removed; STL sort algorithms are used instead.
Comparator objects are mostly reimplemented as local classes.

0024750: Replace instantiations of TCollection generic classes by NCollection templates -- manual changes
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.
Global static functions instantiating RTTI descriptors for class types (used though STANDARD_TYPE macro) are replaced by template static method Instance() of the class Standard_Type.
Implementation of RTTI is revised accordingly (global registry of type descriptors added to ensure single instance of each type descriptor shared by all dynamic libraries).
Obsolete methods of Standard_Type class (IsInstance(), Ancestors()) are removed; new method Parent() is added returning type descriptor of the parent class.
Class Standard_AncestorIterator is removed; this iteration can be easily done by recursive calls to Standard_Type::Parent().
Definition of macro STANDARD_TYPE() moved from Standard_Macro.hxx to Standard_DefineHandle.hxx.
Inclusion of Standard_Type.hxx and the class header is now necessary for use of method DownCast() and function STANDARD_TYPE() for the class.
In general, Standard_Type.hxx should be included now instead of Standard_DefineHandle.hxx in places where these macros are used.
Macro DEFINE_STANDARD_EXCEPTION changed to define all methods inline; macro IMPLEMENT_STANDARD_EXCEPTION becomes obsolete.
Macros IMPLEMENT_DOWNCAST, IMPLEMENT_STANDARD_* become deprecated, they are still defined (as empty) for compatibility.
Implementation of Handle classes became fully inline.
Method get() is added in Handle classes returning pointer to the contained object.
RTTI removed from NCollection_Handle class.
Standard_Persistent is made empty descendant of Standard_Transient, instead of implementing its own hierarchy with reference counting.
Unused enumerations Standard_InternalType, Standard_WayOfLife, Standard_KindOfType are removed.
Global function HashCode() accepting Handle(Standard_Transient) is removed; HashCode() for Standard_CString with length should be used instead.
DRAW command dtryload is added for testing dynamic load / unload of the specified library.
New test perf fclasses bug24947 uses this command to measure performance of multiple (1000 times) loading / unloading OCCT libs on example of TKSTEP.
0025613: Wrong distance found by xdistef command for attached shapes
1. Divide B-spline curve on sub-intervals (bounded by knots values).
2. Class BRepLib_CheckCurveOnSurface_TargetFunc has been optimized for future implementation to checkshape algorithm (Adaptors are used instead of Geom_Curve(Surface)).
3. Parallelization of new algorithm.
