* | Issue #18408: type_new() and PyType_FromSpecWithBases() now raise MemoryErrorVictor Stinner2013-07-151-2/+6
| | | | | | | | on memory allocation failure
* | Issue #18408: Don't check unicode consistency in _PyUnicode_HAS_UTF8_MEMORY()Victor Stinner2013-07-151-4/+2
| | | | | | | | | | | | | | | | | | | | | | and _PyUnicode_HAS_WSTR_MEMORY() macros These macros are called in unicode_dealloc(), whereas the unicode object can be "inconsistent" if the creation of the object failed. For example, when unicode_subtype_new() fails on a memory allocation, _PyUnicode_CheckConsistency() fails with an assertion error because data is NULL.
* | Issue #18408: PyObject_Call() now fails with an assertion error in debug modeVictor Stinner2013-07-151-1/+7
| | | | | | | | | | if the function called failed whereas no exception was raised, to detect bugs earlier.
* | Issue #18408: pmerge() help of mro_implementation() now raises MemoryError onVictor Stinner2013-07-111-2/+4
| | | | | | | | | | | | | | memory allocation failure Replace also PyMem_Free() with PyMem_FREE() to be consistent with the rest of the function.
* | Issue #18408: In debug mode, PyCFunction_Call() now checks if an exception wasVictor Stinner2013-07-111-7/+23
| | | | | | | | | | raised if the result is NULL to help to find bugs in C mode (get the error earlier than the SystemError in ceval.c).
* | Issue #18408: slot_tp_str() must not fallback on slot_tp_repr() on errorVictor Stinner2013-07-111-19/+2
| | | | | | | | | | | | | | | | | | type->tp_str must not point to slot_tp_str() if type has no __str__ attribute, so there is no reason for slot_tp_str() to fallback on slot_tp_str() on lookup error. Moreover, calling PyErr_Clear() may hide a real bug like MemoryError. If __str__ attribute is removed, slots must be updated (which is done by type_setattro()).

* | Issue #18408: Fix _PyMem_DebugRealloc()Victor Stinner2013-07-081-6/+8
| | | | | | | | | | | | | | | | Don't mark old extra memory dead before calling realloc(). realloc() can fail and realloc() must not touch the original buffer on failure. So mark old extra memory dead only on success if the new buffer did not move (has the same address).
* | Issue #18408: _PyUnicodeWriter_Finish() now clears its buffer attribute in allVictor Stinner2013-07-081-3/+6

| | | | | | | | so _PyUnicodeWriter_Dealloc() can be called on the writer after finish.

| | | | | | | | | | | | | | * Replace malloc() with PyMem_RawMalloc() * Replace PyMem_Malloc() with PyMem_RawMalloc() where the GIL is not held. * _Py_char2wchar() now returns a buffer allocated by PyMem_RawMalloc(), instead of PyMem_Malloc()

* | Issue #15767: Introduce ModuleNotFoundError, a subclass ofBrett Cannon2013-06-121-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
