Victor Stinner fdeb6ec45a Issue #14432: Remove the thread state field from the frame structure. Fix a
crash when a generator is created in a C thread that is destroyed while the
generator is still used. The issue was that a generator contains a frame, and
the frame kept a reference to the Python state of the destroyed C thread. The
crash occurs when a trace function is setup.

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.

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

storage).
