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.

Brett Cannon 7385adc84c Issue #15715: Ignore failed imports triggered by the use of fromlist. 
When the fromlist argument is specified for __import__() and the
attribute doesn't already exist, an import is attempted. If that fails
(e.g. module doesn't exist), the ImportError will now be silenced (for
backwards-compatibility). This *does not* affect
``from ... import ...`` statements.

Thanks to Eric Snow for the patch and Simon Feltman for reporting the
regression.

Nick Coghlan 336d9ac6bd Issue #15425: Don't rely on the assumption that the current working directory is on sys.path (this will hopefully appease the XP buildbots) 2012-07-31 21:39:42 +10:00

Brett Cannon ba52586f76 Running the importlib tests from test_import is redundant as there is

Brett Cannon fd0741555b Issue #2377: Make importlib the implementation of __import__(). 
importlib._bootstrap is now frozen into Python/importlib.h and stored
as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen
code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().
