M RemoteDebugger.py M ScriptBinding.py Restart the execution server with a clean environment and execute the active module from scratch upon activation of Run/F5. Add functionality to PyShell.py to restart the execution server in a new subprocess. The server makes a connection to the Idle client which sends a block of code to be executed. Modify ScriptBinding.py to restart the subprocess upon Run/F5, assuming that an execution is not currently in progress. Remove Import Module functionality, not required now that the code is executed in a clean environment. If the Debugger is active, also restart the subprocess side of the split debugger. Add functionality to RemoteDebugger.py to support this. At this time breakpoints will be lost in the subprocess if Run/F5 is activated. A subsequent checkin of PyShell.py will implement reloading of the breakpoints into the subprocess debugger. I'm keeping this separate as the design may change.
