| Summary | 0022816: Enhancement request: new[]/delete[] operators should be redefined to use OCC allocation | ||||||||
| Description | Post from the Forum - http://www.opencascade.org/org/forum/thread_22253/. [^] RLN contribution. "The new[] operator (e.g. used in arrays/vectors) is not redefined in OCC classes and thus does not take advantage of OCC memory allocation mechanism (Standard::Allocate(), Standard::Free()). Instead it defaults to standard new/delete [] operators. Example: TopTools_Array1OfShape anArray (1, 10); will underneath call new TopoDS_Shape[10] which will NOT call Standard::Allocate(). We discussed this issue with ABV a while ago, so maybe there is already a bug registered. In this case, please just post an ID here for future tracking." | ||||||||

I suggest that along with this correction we pack all OCCT-specific declarations of new / delete into a macro (to be defined in Standard_Macro.hxx) and use it in all relevant classes. |

Operators new[]/delete[] redefined in the macro OVERRIDE_MEMORY_OPERATORS (src/Standard/Standard_Macro.hxx) to use OCC allocation. bug fixed in the branch: http://svn/svn/occt/branches/OCC22815 [^] Dear Andrey, Please review. |

General comment: Please think of a general policy of naming macros to ensure consistency and easy attribution to Open CASCADE. Often, macros are named with product prefix and underscores, for instance this could be: __OCC_OVERRIDE_MEMORY_OPERATORS |

See review remarks in 0022815 |

Roman is right, macros used in installed header files should be prefixed by OCC_ to avoid name clashes. But please do not use leading underscores, such names are reserved in C++. |
|
(0019187) abv (manager) 2012-01-19 20:33 |
Sure these names are reserved, thanks for commenting. We shall consider giving common prefix to macros in the future; in this particular fix I prefer to stick to using currently adopted pattern. |
