The code in Standard_Type::type_instance<T>::get() distinguishes between compilers supporting and not supporting N2660. VS2013 was incorrectly considered as supporting, although the comment stated the opposite.
The fix makes VS2013 treated as not supporting N2660.
AIS_ColorScale, AIS_Dimension - the protected method DrawText()
has been renamed to drawText() to avoid name collisions with macros.
_MSC_VER/_WIN32 misuse has been fixed in several places.
Header <malloc.h> is now included where alloca() is used.
Draw_Window - dllimport flag has been dropped from inline methods.
TKernel - mandatory dependencies Winspool.lib and Psapi.lib
are now linked explicitly (instead of msvc-specific pragma syntax).
CMake scripts - the option -std=c++0x has been replaced by -std=gnu++0x
for mingw to allow extensions (like _wfopen() and others).
The minimum Windows version has been set to _WIN32_WINNT=0x0501.
Invalid options "-z defs" and "-lm" have been dropped for mingw.
Flag --export-all-symbols has been added to CMAKE_SHARED_LINKER_FLAGS
to workaround missing vtable symbols when using mingw.
FreeType is now linked explicitly on Windows.
Draw::Load() - "lib" suffix is now prepended on mingw as well.
Drop redundant declaration of _TINT from OSD_WNT_1.hxx.
NCollection_UtfString::FromLocale() - platform-specific code has been moved to .cxx file.
Draw_BasicCommands - fixed incorrect mingw64 version macros.
genproj, cbp - added workaround for process argument list limits on Windows.
TKSTEP linkage is failing on this platform due to too long list of files.
The list of object files to link is now stored in dedicated file which is passed to gcc.
Option "-z defs" removed from CMake linker options to avoid problems when building with different configurations of VTK on Linux
Some MinGW-specific compiler warnings (potentially uninitialized vars, use of NULL, parentheses in conditional expressions) are fixed (speculatively)
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).
Copy constructor and assignment operator from handle of derived type is added in handle class.
They are enabled only if macro OCC_HANDLE_NOCASTS is defined, and operators of cast of handle to reference to handle to base type are disabled in that case.
Useless type casts to handle to base type are removed in GC and GCE2d classes.
Code returning reference to handle from function is corrected to return it either by value or as reference to handle of actual type.
Operator of cast to non-const reference is declared deprecated to produce compiler warning if used (usually implicitly).
OCCT code is updated to avoid that cast, occurring when function accepting non-const reference to handle is called with handle to derived type.
For that, local variable of argument type is passed instead, and down-cast is used to get it to desired type after the call.
A few occurrences of use of uninitialized variable are corrected.
Macro Standard_DEPRECATED("message") can be used in declarations to mark a method deprecated and generate compiler warning when it is used.
If OCCT_NO_DEPRECATED is defined, Standard_DEPRECATED is disabled (defined empty).
Standard_OutOfMemory exception is refactored so as to avoid memory allocations (which will likely fail) when it is raised:
- method NewInstance() returns static instance (singleton)
- method Raise() raises copy of that singleton, resetting its message string
- message string is stored as field, not allocated dynamically (thus maximum message length is limited by buffer size)
Class Standard_Failure slightly revised: method Destroy() is merged to destructor, methods Get/SetMessageString() are made virtual.
Add test case for the bug
Global type descriptors are restored for VC++ 10 - 12 and GCC before 4.3.
Checks of compiler support of C++ features are corrected for GCC, ICC, and CLang in Standard_Handle.hxx
TDocStd_Application class extended to open/save a document of XmlOcaf and BinOcaf format
from/to standard SEEKABLE stream object which should support SEEK functionality.
Open and SaveAs DRAW commands got new additional argument "-stream" to turn on using of stream functionality.
The main changes for BinOcaf format applied in:
FSD_BinaryFile class (static method using standard stream added)
BinLDrivers_DocumentRetrievalDriver and BinLDrivers_DocumentStorageDriver classes use standard stream object as an argument
The main changes for XmlOcaf format applied in:
LDOMParser and LDOM_XmlWriter classes use standard stream object as an argument
Unused class FSD_Archive and its siblings removed from MFC samples.
Restored possibility to have out-of-line implementation of DynamicCast() and STANDART_TYPE():
- Macro STANDARD_TYPE() now resolves to function get_type_descriptor() of the class
- Macro DEFINE_STANDARD_RTTI is replaced by two variants:
- DEFINE_STANDARD_RTTI_INLINE works as before, defining DynamicCast() and get_type_descriptor() as inline functions
- DEFINE_STANDARD_RTTIEXT declares DynamicCast() and get_type_descriptor() as exported
- Macro IMPLEMENT_STANDARD_RTTIEXT provides definition of DynamicCast() and get_type_descriptor() for a class
Upgrade script amended to replace DEFINE_STANDARD_RTTI by pair of DEFINE_STANDARD_RTTIEXT / IMPLEMENT_STANDARD_RTTIEXT if source file with the same name as header is found in the same folder, and by DEFINE_STANDARD_RTTI_INLINE if either source is not found or class is defined in the source (i.e. not in header)
Upgrade tool improved to recognize include statements with path prefix, like #include <occt/gp_Pnt.hxx>
Code corrected to eliminate warnings reported by upgrade tool.
Template of CXX file for testing upgrade tool added.
Documentation of upgrade procedure updated.
Warnings "conversion requires a narrowing conversion" were eliminated: IVtk_IdType is defined via vtkIdType from now.
Check of bitness of VTK libraries is added, to ensure that OCCT and VTK use the same bitness.
HashCode() function for long long int added in Standard_Integer.hxx to handle 64-bit integers
1) Macro definition WNT replaced by _WIN32 and _MSC_VER for platform and compiler detection accordingly.
2) Macro definition LIN replaced by __linux__ macro.
3) Macro definition DEB replaced by OCCT_DEBUG macro.
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.
Draw_Window_1.mm, Cocoa_Window.mm - fix compilation issues on OS X
CMake env.build.sh - fix libraries path
MSVC project templates - /bigobj flag added for all configurations (x64, x86, release and debug)
Standard_Type.hxx - enforce initialization of all type descriptors at library load
All CMake meta-projects for OCCT are put to OCCT code (including fragments previously generated by WOK).
"/bigobj" compiler flag added to TKQADraw because of the size of its object file
[GeomToStep & Graphic3d] private headers are included from current dir of including source file
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
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
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.
Adaptations for compiling with GCC 4.7
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.
The empty copy constructor, assignemnts operator, default constructors added to the following classes:
The following classes use “new” function without Handles:
- Select3D_PointData
- BSB_T3Bits
- IntPatch_InfoPD
- LDOM_StringElem
- BinomAllocator
- ProjLib_OnSurface
- Standard_MMgrFactory
Useless declaration of default constructor have been deleted.
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.
