* Issue #15767: Touch up ModuleNotFoundError usage by import.Brett Cannon2013-06-131-0/+3
| | | | | | | | | | | | | Forgot to raise ModuleNotFoundError when None is found in sys.modules. This led to introducing the C function PyErr_SetImportErrorSubclass() to make setting ModuleNotFoundError easier. Also updated the reference docs to mention ModuleNotFoundError appropriately. Updated the docs for ModuleNotFoundError to mention the None in sys.modules case. Lastly, it was noticed that PyErr_SetImportError() was not setting an exception when returning None in one case. That issue is now fixed.
* Issue #15767: Introduce ModuleNotFoundError, a subclass ofBrett Cannon2013-06-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

NOTE: This change is smaller compared to 3.2 as much of this cleanup had already been done. I added the comment that my change in 3.2 added so that the code would match up. Otherwise this just adds or synchronizes appropriate UL designations on some constants to be pedantic. In practice we require compiling everything with -fwrapv which forces overflow to be defined as twos compliment but this keeps the code cleaner for checkers or in the case where someone has compiled it without -fwrapv or their compiler's equivalent. We could work to get rid of the -fwrapv requirement in 3.4 but that requires more planning. Found by Clang trunk's Undefined Behavior Sanitizer (UBSan). Cleanup only - no functionality or hash values change.
