Victor Stinner ffff763161 Issue #18519: Fix test_sqlite on old versions of libsqlite3
With old SQLite versions, _sqlite3_result_error() sets a new Python exception,
so don't restore the previous exception.

Victor Stinner 044c516854 Issue #18609, #18408: _ctypes_add_traceback() now clears the current exception
while adding the traceback, because it may call indirectly a Python function
and Python functions must not be called with an exception set.

In the case of the issue #18609, _ctypes_add_traceback() called the iso8859-1
decoder which is implemented in Python. Python has a ISO-8859-1 codec
implemented in C. It is not used because PyUnicode_Decode() only uses the C
codec for other names (aliases) of this codec ("latin-1", "latin1" and
"iso-8859-1").

Raymond Hettinger 77578204d6 Restore the data block size to 62.
The former block size traded away good fit within cache lines in
order to gain faster division in deque_item().  However, compilers
are getting smarter and can now replace the slow division operation
with a fast integer multiply and right shift.  Accordingly, it makes
sense to go back to a size that lets blocks neatly fill entire
cache-lines.

GCC-4.8 and CLANG 4.0 both compute "x // 62" with something
roughly equivalent to "x * 9520900167075897609 >> 69".

The "Gestalt" function on OSX is deprecated (starting with OSX 10.8),
remove its usage from the stdlib. The patch removes a number of private
functions and a private module, but does not change the public API.

The removed code was effectively dead, the platform module has used
other code to fetch the OSX version for years and could only use
on the Gestalt-based code as a fallback. That fallback can only trigger
on broken OSX installs (that is, someone has removed parts of the system
install)

Victor Stinner 68c8ea25f1 Issue #18408: Fix _Pickler_New() and _Unpickler_New(): initialize all
attributes before handling errors

_Pickler_New() now calls PyObject_GC_Del() instead of Py_DECREF() on error,
because the pickle object is created using PyObject_GC_New().

Fix a crash in the destructor when an attribute is not initiallized.

Victor Stinner 0507bf56f0 Issue #3329: Implement the PEP 445
Add new enum:

* PyMemAllocatorDomain

Add new structures:

* PyMemAllocator
* PyObjectArenaAllocator

Add new functions:

* PyMem_RawMalloc(), PyMem_RawRealloc(), PyMem_RawFree()
* PyMem_GetAllocator(), PyMem_SetAllocator()
* PyObject_GetArenaAllocator(), PyObject_SetArenaAllocator()
* PyMem_SetupDebugHooks()

Changes:

* PyMem_Malloc()/PyObject_Realloc() now always call malloc()/realloc(), instead
  of calling PyObject_Malloc()/PyObject_Realloc() in debug mode.
* PyObject_Malloc()/PyObject_Realloc() now falls back to
  PyMem_Malloc()/PyMem_Realloc() for allocations larger than 512 bytes.
* Redesign debug checks on memory block allocators as hooks, instead of using C
  macros
