* | Issue #3329: Add new APIs to customize memory allocatorsVictor Stinner2013-06-151-20/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 #13992: The trashcan mechanism is now thread-safe. This eliminatesAntoine Pitrou2012-09-061-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sporadic crashes in multi-thread programs when several long deallocator chains ran concurrently and involved subclasses of built-in container types. Because of this change, a couple extension modules compiled for 3.2.4 (those which use the trashcan mechanism, despite it being undocumented) will not be loadable by 3.2.3 and earlier. However, extension modules compiled for 3.2.3 and earlier will be loadable by 3.2.4.

* | - Issue #10181: New memoryview implementation fixes multiple ownershipStefan Krah2012-02-251-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and lifetime issues of dynamically allocated Py_buffer members (#9990) as well as crashes (#8305, #7433). Many new features have been added (See whatsnew/3.3), and the documentation has been updated extensively. The ndarray test object from _testbuffer.c implements all aspects of PEP-3118, so further development towards the complete implementation of the PEP can proceed in a test-driven manner. Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review and many ideas. - Issue #12834: Fix incorrect results of memoryview.tobytes() for non-contiguous arrays. - Issue #5231: Introduce memoryview.cast() method that allows changing format and shape without making a copy of the underlying memory.
