First patch in iterative renovation of exceptions.
- Simplify exception classes to be container of data only.
- Removed redundant inclusion of <Standard_Type.hxx> in various header files across the project.
- Removed Set methods for failure and its define template.
- Removed Raise and Rerise static methods.
- Remove Instance and Throw methods
- Deprecated getting message with old approach, and moving to what()
- Update ErrorHandler to handle only specific list of exceptions.
Refactored Standard_ErrorHandler to use thread_local storage for the error handler stack
instead of a global list protected by mutex. This eliminates locking overhead entirely
since each thread only accesses its own error handlers.
Changes:
- Replaced global mutex-protected stack with thread_local Top pointer
- Simplified FindHandler() to directly return the thread-local Top
- Removed Catches() and LastCaughtError() methods (no longer needed)
- Added Raise() method for re-throwing caught exceptions
- Removed obsolete member variables: myStatus, myThread
- Deleted unused headers: Standard_HandlerStatus.hxx, Standard_JmpBuf.hxx, Standard_PErrorHandler.hxx
- Updated OCC_CATCH_SIGNALS macro to use new Raise() method
- Added automated migration scripts for handle syntax, standard types, and macros
- Deprecated legacy `Standard_*` types and macros in favor of native C++ equivalents
- Introduced modern `occ` namespace with template-based type checking helpers
- Enhanced NCollection macros to support variadic arguments for complex template types- Added automated migration scripts for handle syntax, standard types, and macros
- Deprecated legacy `Standard_*` types and macros in favor of native C++ equivalents
- Introduced modern `occ` namespace with template-based type checking helpers
- Enhanced NCollection macros to support variadic arguments for complex template types
- Added constexpr to constructors and methods in both classes, with special handling for already-normalized inputs
- Refactored coordinate access methods to avoid pointer arithmetic (incompatible with constexpr)
- Implemented a dual-path approach: fast path for normalized inputs (constexpr-compatible) and slow path for runtime normalization
- Replaced manual absolute value logic (conditional negation) with `std::abs` for clarity
- Added `const` qualifiers to variables that are not modified after initialization
- Moved variable declarations closer to their first use and removed unused variable assignments
Majority of functions now simply call same functions from std namespace.
Functions that duplicate std namespace functionality are declared
deprecated.
Calls of deprecated functions are replaced with std functions calls.
- Included <mutex> in Interface_Category.cxx to support thread synchronization.
- Added <windows.h> in Standard_StackTrace.cxx for Windows-specific functionality.
- Removed deprecated macro usage example in Standard_Macro.hxx to clean up the code.
- Added `Standard_MACRO_DEPRECATED` macro to mark preprocessor macros as deprecated with compiler-specific warning generation
- Simplified deprecated macros (`Standard_OVERRIDE`, `Standard_DELETE`, `Standard_FALLTHROUGH`, `Standard_NODISCARD`, `Standard_THREADLOCAL`, `Standard_ATOMIC`, `Standard_Noexcept`) to expand directly to their C++11/C++17 equivalents while emitting deprecation warnings
- Removed complex conditional compilation logic that checked for compiler/standard support
- Introduces position and dynamic_cast based logic in AddValuesSeparator to decide when to append ", ".
- Adds new GTest suite Standard_Dump_Test.cxx plus an extra Bnd_Box JSON test in TKMath.
- Updates FILES.cmake to include the new test file.
- Replace legacy Standard_Mutex usage across many modules with std::mutex.
- Include <mutex> where needed and remove <Standard_Mutex.hxx> includes.
- Replace Standard_Mutex::Sentry / explicit Lock/Unlock with std::lock_guard or std::unique_lock.
- Convert optional/heap mutex holders to std::unique_ptr<std::mutex> and adapt locking accordingly.
- Simplify several singleton initializations (remove manual double-checked locking where safe).
- Use thread_local for per-thread flags instead of ad-hoc mutex protection.
- Fix BVH_BuildQueue Fetch logic to preserve thread counters and wasBusy handling.
- Remove obsolete TopTools_MutexForShapeProvider sources and update FILES.cmake.
This modernizes mutex usage, reduces dependency on custom mutex types and improves clarity of locking patterns.
- Mark many methods and operators noexcept (iterators, containers, allocators, maps, lists, buffers, UTF/string utilities, etc.)
- Add constexpr to suitable functions and factory methods (matrices, vectors, static sizes) to enable compile-time usage
- Replace non-constexpr memcpy usages in NCollection_Mat3/NCollection_Mat4 with constexpr-friendly initialization and promote static arrays to constexpr
- Make several small API improvements: stronger const-correctness, noexcept on allocation/deallocation operators, delete forbidden copy ctors/assign where appropriate
- Remove obsolete NCollection_TypeDef.hxx and update FILES.cmake
- Miscellaneous small refactors to support modern C++ patterns and better compile-time guarantees
- Updated preprocessor directives to utilize Standard_CPP17_OR_HIGHER instead of direct __cplusplus checks.
- Removed unnecessary preprocessor checks for C++17 in TCollection_AsciiString implementation and tests.
- Enhanced code readability and maintainability by centralizing C++ version checks.
- Updates function calls from `sprintf` to `Sprintf` across the entire codebase
- Updates comments and documentation references to reflect the new function name
- Adds format attribute annotations to the `Sprintf` function declaration for better compiler validation
- Updates `.clang-format` to include `OCC_CATCH_SIGNALS`, `DEFINE_STANDARD_RTTIEXT`, and `Draw_Drawable3D_FACTORY` as statement macros
- Adds a GitHub action step to automatically remove empty lines after `Standard_DEPRECATED` macro declarations
- Reformats numerous files by removing blank lines after deprecated method declarations and improving macro formatting
- Standardizes comment formatting by replacing detailed comment blocks with a uniform "//=================================================================================================" separator
- Removes redundant "function:" and "purpose:" fields that often contained minimal or no useful information
- Maintains code functionality while improving visual consistency across the codebase
- Replace all `Standard_Atomic_Increment`/`Decrement` calls and `volatile` counters with `std::atomic` usage.
- Rewrite `Standard_Condition` header to use `std::mutex`, `std::condition_variable`, and `std::atomic<bool>`.
- Deprecate old atomic APIs in `Standard_Atomic.hxx`.
- Added missing break statements in switch-case blocks in LDOMBasicString, LDOM_BasicElement, PCDM_ReadWriter, and IntCurve_IntConicConic_1 to prevent fall-through behavior.
- Enhanced Standard_Macro.hxx to support fallthrough attributes across different compilers.
- Corrected the use of std::forward in Standard_MemoryUtils.hxx for better type deduction.
- Replaced raw arrays with NCollection_Array1 in AdvApp2Var_SysBase for improved memory safety.
- Updated Extrema_ExtCC2d to utilize smart pointers for better memory management and avoid potential leaks.
- Refactored Units_UnitsDictionary to use NCollection_Array2 for matrix representation, improving readability and maintainability.
- Initialized TranFirst and TranLast in TopTrans_CurveTransition constructor for better default state management.
- Set myStatus in ShapeConstruct_ProjectCurveOnSurface constructor to ensure proper initialization.
- Changed matrix access in Units_UnitsDictionary to use NCollection_Array2 syntax for consistency.
Reorganizing structure to have Module/TK/Package/FILES structure.
New structure reflect the structure inside IDE.
Migrate FILES, PACKAGES, EXTRLIB to CMake version to handle changes on updates.
No changes were done to installation layout, all installation result keep as before.
The migration was done using python script, see PR, which refactor automatically the structure.
Updated doc generation to have valid path to modules, toolkits and packages.
In case of PR into new version, IR-790 can be used as a target for the previous version.
