    Research direction

    No implementation file or test is named. Start by reading BPO issue 29819 and its dependency, bpo-29852, then locate truncate() in the Python IO library and its existing tests; done means avoiding OverflowError where the requested behavior permits it without breaking current truncate() semantics.
