Victor Stinner ace47d7efd Issue #18408: PyEval_EvalFrameEx() and PyEval_CallObjectWithKeywords() now fail
with an assertion error if they are called with an exception set
(PyErr_Occurred()).

If these functions are called with an exception set, the exception may be
cleared and so the caller looses its exception.

Add also assertions to PyEval_CallObjectWithKeywords() and call_function() to
check if the function succeed with no exception set, or the function failed
with an exception set.

Victor Stinner f243ee4055 Issue #18408: add more assertions on PyErr_Occurred() in ceval.c to detect bugs

Victor Stinner 7eab0d000c Issue #18408: Fix PyEval_EvalFrameEx() for MemoryError
Don't pass a NULL traceback to PyException_SetTraceback(): pass Py_None.
Passing NULL would raise a new exception.

Brett Cannon a79e4fb38d Issue #18342: Use the repr of a module name for ``from ... import
...`` when an ImportError occurs.

Other cases had already been switched over to using the repr.

Thanks to Tomasz Maćkowiak for the patch.

Victor Stinner aaa8ed8b84 Issue #18408: Fix call_exc_trace(): if the traceback is NULL, use None when
building the tuple (type, value, traceback) passed to the callback.

PyTuple_Pack() does crash if an argument is NULL.

Brett Cannon 679ecb565b Issue #15767: back out 8a0ed9f63c6e, finishing the removal of
ModuleNotFoundError.
2013-07-04 17:51:50 -04:00
Brett Cannon b1611e2772 Issue #15767: Introduce ModuleNotFoundError, a subclass of
ImportError.

The exception is raised by import when a module could not be found.
Technically this is defined as no viable loader could be found for the
specified module. This includes ``from ... import`` statements so that
the module usage is consistent for all situations where import
couldn't find what was requested.

This should allow for the common idiom of::

  try:
    import something
  except ImportError:
    pass

to be updated to using ModuleNotFoundError and not accidentally mask
ImportError messages that should propagate (e.g. issues with a
loader).

This work was driven by the fact that the ``from ... import``
statement needed to be able to tell the difference between an
ImportError that simply couldn't find a module (and thus silence the
exception so that ceval can raise it) and an ImportError that
represented an actual problem.

Antoine Pitrou 8408cea0cd Issue #17094: Clear stale thread states after fork().
Note that this is a potentially disruptive change since it may
release some system resources which would otherwise remain
perpetually alive (e.g. database connections kept in thread-local
storage).

Victor Stinner b0b224233e Issue #14385: Support other types than dict for __builtins__
It is now possible to use a custom type for the __builtins__ namespace, instead
of a dict. It can be used for sandboxing for example.  Raise also a NameError
instead of ImportError if __build_class__ name if not found in __builtins__.

Benjamin Peterson 2afe6aeae8 perform yield from delegation by repeating YIELD_FROM opcode (closes #14230)
