| Summary | 0028203: Coding rules - check testing with MMGT_CLEAR turned OFF | ||||
| Description | For the moment, the option MMGT_CLEAR is turned ON by both - default environment scripts and within Standard.cxx itself:
aVar = getenv ("MMGT_CLEAR");
Standard_Boolean toClear = (aVar ? (atoi (aVar) != 0) : Standard_True);
This option is intended to clear (fill with zeros) memory blocks allocated by standard OCCT allocators (e.g. Standard::Allocate()). This practice, however, has side effects: - It might hide possible issues in OCCT algorithms due to usage of uninitialized memory. - Zeroing memory increases time required for memory allocation. Therefore, it is proposed to perform regression testing of OCCT with MMGT_CLEAR turned OFF (set "MMGT_CLEAR=0") and collect information about current state (e.g. if there some regressions / the performance difference). | ||||
