* Issue #3329: Add new APIs to customize memory allocatorsVictor Stinner2013-06-142-157/+364
| | | | | | | | | | | | | | | | | | | | * Add a new PyMemAllocators structure * New functions: - PyMem_RawMalloc(), PyMem_RawRealloc(), PyMem_RawFree(): GIL-free memory allocator functions - PyMem_GetRawAllocators(), PyMem_SetRawAllocators() - PyMem_GetAllocators(), PyMem_SetAllocators() - PyMem_SetupDebugHooks() - _PyObject_GetArenaAllocators(), _PyObject_SetArenaAllocators() * Add unit test for PyMem_Malloc(0) and PyObject_Malloc(0) * Add unit test for new get/set allocators functions * PyObject_Malloc() now falls back on PyMem_Malloc() instead of malloc() if size is bigger than SMALL_REQUEST_THRESHOLD, and PyObject_Realloc() falls back on PyMem_Realloc() instead of realloc() * PyMem_Malloc() and PyMem_Realloc() now always call malloc() and realloc(), instead of calling PyObject_Malloc() and PyObject_Realloc() in debug mode
* 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.

* | Issue #9566: Fix a compiler warning on Windows 64-bit in namespace_init()Victor Stinner2013-06-041-1/+1
| | | | | | | | | | | | The result type is int, return -1 to avoid a compiler warning (cast Py_ssize_t to int). PyObject_Size() can only fail with -1, and anyway a constructor should return -1 on error, not an arbitrary negative number.

* | #17115,17116: Have modules initialize the __package__ and __loader__Brett Cannon2013-05-041-13/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | attributes to None. The long-term goal is for people to be able to rely on these attributes existing and checking for None to see if they have been set. Since import itself sets these attributes when a loader does not the only instances when the attributes are None are from someone overloading __import__() and not using a loader or someone creating a module from scratch. This patch also unifies module initialization. Before you could have different attributes with default values depending on how the module object was created. Now the only way to not get the same default set of attributes is to circumvent initialization by calling ModuleType.__new__() directly.
