| Summary | 0033351: Data Exchange, Step - Improvement for thread safety of the STEP translator | ||||
| Description | The major problem is occt\src\StepData\StepData_GlobalFactors.hxx It is a singleton. We need to make it as a field of session(StepData_StepModel) Additinally All methods and functions that work with StepData_GlobalFactors must have access to the StepData_StepModel This can be done via optional parameter functions (theTP-reading, theFP-writing, theModel, or a value directly from Standard_Real) Or add/use a field in a class of the same type. The reason for this is thread-safety. StepData_GlobalFactors are static fields - containers (singletons) Fix for objects unique to one session - will allow to read step in different threads different files. The next step in this ticket is to isolate all static variables. Isolation is using Standard_mutex ::Lock ::Unlock + Change the type of static controllers to bool | ||||
