* | Remove the freelist scheme for setobjects.Raymond Hettinger2013-09-081-1/+0
| | | | | | | | | | | | | | | | | | The setobject freelist was consuming memory but not providing much value. Even when a freelisted setobject was available, most of the setobject fields still needed to be initialized and the small table still required a memset(). This meant that the custom freelisting scheme for sets was providing almost no incremental benefit over the default Python freelist scheme used by _PyObject_Malloc() in Objects/obmalloc.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
