-/* Protection against deeply nested recursive calls
-
-   In Python 3.0, this protection has two levels:
-   * normal anti-recursion protection is triggered when the recursion level
-     exceeds the current recursion limit. It raises a RecursionError, and sets
-     the "overflowed" flag in the thread state structure. This flag
-     temporarily *disables* the normal protection; this allows cleanup code
-     to potentially outgrow the recursion limit while processing the
-     RecursionError.
-   * "last chance" anti-recursion protection is triggered when the recursion
-     level exceeds "current recursion limit + 50". By construction, this
-     protection can only be triggered when the "overflowed" flag is set. It
-     means the cleanup code has itself gone into an infinite loop, or the
-     RecursionError has been mistakingly ignored. When this protection is
-     triggered, the interpreter aborts with a Fatal Error.
-
-   In addition, the "overflowed" flag is automatically reset when the
-   recursion level drops below "current recursion limit - 50". This heuristic
-   is meant to ensure that the normal anti-recursion protection doesn't get
-   disabled too long.
-
-   Please note: this scheme has its own limitations. See:
-   http://mail.python.org/pipermail/python-dev/2008-August/082106.html

-/* Interface for threads.
-
-   A module that plans to do a blocking system call (or something else
-   that lasts a long time and doesn't touch Python data) can allow other

-    Py_END_ALLOW_THREADS
-    ...interpret result here...
-

-   To leave the block in the middle (e.g., with return), you must insert
-   a line containing Py_BLOCK_THREADS before the return, e.g.
-
-    if (...premature_exit...) {

-    }
-    Py_UNBLOCK_THREADS
-
-   For convenience, that the value of 'errno' is restored across
-   Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
-

-
-       * if Py_SetStandardStreamEncoding() has been called: they have the
-         highest priority;
-       * PYTHONIOENCODING environment variable;
-       * The UTF-8 Mode uses UTF-8/surrogateescape;
-       * If Python forces the usage of the ASCII encoding (ex: C locale
-         or POSIX locale on FreeBSD or HP-UX), use ASCII/surrogateescape;
-       * locale encoding: ANSI code page on Windows, UTF-8 on Android and
-         VxWorks, LC_CTYPE locale encoding on other platforms;
-       * On Windows, "surrogateescape" error handler;
-       * "surrogateescape" error handler if the LC_CTYPE locale is "C" or "POSIX";
-       * "surrogateescape" error handler if the LC_CTYPE locale has been coerced
-         (PEP 538);
-       * "strict" error handler.
-
-       Supported error handlers: "strict", "surrogateescape" and
-       "surrogatepass". The surrogatepass error handler is only supported
-       if Py_DecodeLocale() and Py_EncodeLocale() use directly the UTF-8 codec;
-       it's only used on Windows.
-
-       initfsencoding() updates the encoding to the Python codec name.
-       For example, "ANSI_X3.4-1968" is replaced with "ascii".
-
-       On Windows, sys._enablelegacywindowsfsencoding() sets the
-       encoding/errors to mbcs/replace at runtime.

-/* Trashcan mechanism, thanks to Christian Tismer.
-
-When deallocating a container object, it's possible to trigger an unbounded
-chain of deallocations, as each Py_DECREF in turn drops the refcount on "the
-next" object in the chain to 0.  This can easily lead to stack overflows,
-especially in threads (which typically have less stack space to work with).
-
-A container object can avoid this by bracketing the body of its tp_dealloc
-function with a pair of macros:
-
-static void
-mytype_dealloc(mytype *p)
-{
-    ... declarations go here ...
-
-    PyObject_GC_UnTrack(p);        // must untrack first
-    Py_TRASHCAN_BEGIN(p, mytype_dealloc)
-    ... The body of the deallocator goes here, including all calls ...
-    ... to Py_DECREF on contained objects.                         ...
-    Py_TRASHCAN_END                // there should be no code after this
-}
-
-CAUTION:  Never return from the middle of the body!  If the body needs to
-"get out early", put a label immediately before the Py_TRASHCAN_END
-call, and goto it.  Else the call-depth counter (see below) will stay
-above 0 forever, and the trashcan will never get emptied.
-
-How it works:  The BEGIN macro increments a call-depth counter.  So long
-as this counter is small, the body of the deallocator is run directly without
-further ado.  But if the counter gets large, it instead adds p to a list of
-objects to be deallocated later, skips the body of the deallocator, and
-resumes execution after the END macro.  The tp_dealloc routine then returns
-without deallocating anything (and so unbounded call-stack depth is avoided).
-
-When the call stack finishes unwinding again, code generated by the END macro
-notices this, and calls another routine to deallocate all the objects that
-may have been added to the list of deferred deallocations.  In effect, a
-chain of N deallocations is broken into (N-1)/(PyTrash_UNWIND_LEVEL-1) pieces,
-with the call stack never exceeding a depth of PyTrash_UNWIND_LEVEL.
-
-Since the tp_dealloc of a subclass typically calls the tp_dealloc of the base
-class, we need to ensure that the trashcan is only triggered on the tp_dealloc
-of the actual class being deallocated. Otherwise we might end up with a
-partially-deallocated object. To check this, the tp_dealloc function must be
-passed as second argument to Py_TRASHCAN_BEGIN().

-/* This file defines dynamic annotations for use with dynamic analysis
-   tool such as valgrind, PIN, etc.
-
-   Dynamic annotation is a source code annotation that affects
-   the generated code (that is, the annotation is not a comment).
-   Each such annotation is attached to a particular
-   instruction and/or to a particular object (address) in the program.
-
-   The annotations that should be used by users are macros in all upper-case
-   (e.g., _Py_ANNOTATE_NEW_MEMORY).
-
-   Actual implementation of these macros may differ depending on the
-   dynamic analysis tool being used.
-
-   See http://code.google.com/p/data-race-test/  for more information.
-
-   This file supports the following dynamic analysis tools:
-   - None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
-      Macros are defined empty.
-   - ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
-      Macros are defined as calls to non-inlinable empty functions
-      that are intercepted by Valgrind. */

-     Annotations useful when implementing condition variables such as CondVar,

-     user-defined synchronization mechanisms.
-
-     The annotations _Py_ANNOTATE_HAPPENS_BEFORE() and
-     _Py_ANNOTATE_HAPPENS_AFTER() can be used to define happens-before arcs in
-     user-defined synchronization mechanisms: the race detector will infer an
-     arc from the former to the latter when they share the same argument
-     pointer.
-
-     Example 1 (reference counting):
-
-     void Unref() {
-       _Py_ANNOTATE_HAPPENS_BEFORE(&refcount_);
-       if (AtomicDecrementByOne(&refcount_) == 0) {
-         _Py_ANNOTATE_HAPPENS_AFTER(&refcount_);
-         delete this;
-       }
-     }
-
-     Example 2 (message queue):
-
-     void MyQueue::Put(Type *e) {
-       MutexLock lock(&mu_);
-       _Py_ANNOTATE_HAPPENS_BEFORE(e);

- *
- * On platforms that appear to use (see _PyFloat_Init()) IEEE-754 formats

- * the 8-byte format to the IEEE-754 double precision format, although the
- * packing of INFs and NaNs (if such things exist on the platform) isn't
- * handled correctly, and attempting to unpack a string containing an IEEE
- * INF or NaN will raise an exception.
- *
- * On non-IEEE platforms with more precision, or larger dynamic range, than

- * set, most likely OverflowError).

-   NOTE: about untracking of mutable objects.
-
-   Certain types of container cannot participate in a reference cycle, and
-   so do not need to be tracked by the garbage collector. Untracking these
-   objects reduces the cost of garbage collections. However, determining
-   which objects may be untracked is not free, and the costs must be
-   weighed against the benefits for garbage collection.
-
-   There are two possible strategies for when to untrack a container:
-
-   i) When the container is created.
-   ii) When the container is examined by the garbage collector.
-
-   Tuples containing only immutable objects (integers, strings etc, and
-   recursively, tuples of immutable objects) do not need to be tracked.
-   The interpreter creates a large number of tuples, many of which will
-   not survive until garbage collection. It is therefore not worthwhile
-   to untrack eligible tuples at creation time.
-
-   Instead, all tuples except the empty tuple are tracked when created.
-   During garbage collection it is determined whether any surviving tuples
-   can be untracked. A tuple can be untracked if all of its contents are
-   already not tracked. Tuples are examined for untracking in all garbage
-   collection cycles. It may take more than one cycle to untrack a tuple.
-
-   Dictionaries containing only immutable objects also do not need to be
-   tracked. Dictionaries are untracked when created. If a tracked item is
-   inserted into a dictionary (either as a key or value), the dictionary
-   becomes tracked. During a full garbage collection (all generations),
-   the collector will untrack any dictionaries whose contents are not
-   tracked.
-
-   The module provides the python function is_tracked(obj), which returns
-   the CURRENT tracking status of the object. Subsequent garbage
-   collections may change the tracking status of the object.
-
-   Untracking of certain containers was introduced in issue #4688, and
-   the algorithm was refined in response to issue #14775.

-/* Parameters of the integer representation.  There are two different
-   sets of parameters: one set for 30-bit digits, stored in an unsigned 32-bit
-   integer type, and one set for 15-bit digits with each digit stored in an
-   unsigned short.  The value of PYLONG_BITS_IN_DIGIT, defined either at
-   configure time or in pyport.h, is used to decide which digit size to use.
-
-   Type 'digit' should be able to hold 2*PyLong_BASE-1, and type 'twodigits'
-   should be an unsigned integer type able to hold all integers up to
-   PyLong_BASE*PyLong_BASE-1.  x_sub assumes that 'digit' is an unsigned type,
-   and that overflow is handled by taking the result modulo 2**N for some N >
-   PyLong_SHIFT.  The majority of the code doesn't care about the precise
-   value of PyLong_SHIFT, but there are some notable exceptions:
-
-   - long_pow() requires that PyLong_SHIFT be divisible by 5
-
-   - PyLong_{As,From}ByteArray require that PyLong_SHIFT be at least 8
-
-   - long_hash() requires that PyLong_SHIFT is *strictly* less than the number
-     of bits in an unsigned long, as do the PyLong <-> long (or unsigned long)
-     conversion functions
-
-   - the Python int <-> size_t/Py_ssize_t conversion functions expect that
-     PyLong_SHIFT is strictly less than the number of bits in a size_t
-
-   - the marshal code currently expects that PyLong_SHIFT is a multiple of 15
-
-   - NSMALLNEGINTS and NSMALLPOSINTS should be small enough to fit in a single
-     digit; with the current values this forces PyLong_SHIFT >= 9
-
-  The values 15 and 30 should fit all of the above requirements, on any
-  platform.

-/* Object and type object interface */
-
-/*
-Objects are structures allocated on the heap.  Special rules apply to
-the use of objects to ensure they are properly garbage-collected.
-Objects are never allocated statically or on the stack; they must be
-accessed through special macros and functions only.  (Type objects are
-exceptions to the first rule; the standard types are represented by
-statically initialized type objects, although work on type/class unification
-for Python 2.2 made it possible to have heap-allocated type objects too).
-
-An object has a 'reference count' that is increased or decreased when a
-pointer to the object is copied or deleted; when the reference count
-reaches zero there are no references to the object left and it can be
-removed from the heap.
-
-An object has a 'type' that determines what it represents and what kind
-of data it contains.  An object's type is fixed when it is created.
-Types themselves are represented as objects; an object contains a
-pointer to the corresponding type object.  The type itself has a type
-pointer pointing to the object representing the type 'type', which
-contains a pointer to itself!.
-
-Objects do not float around in memory; once allocated an object keeps
-the same size and address.  Objects that must hold variable-size data
-can contain pointers to variable-size parts of the object.  Not all
-objects of the same type have the same size; but the size cannot change
-after allocation.  (These restrictions are made so a reference to an
-object can be simply a pointer -- moving an object would require
-updating all the pointers, and changing an object's size would require
-moving it if there was another object right next to it.)
-
-Objects are always accessed through pointers of the type 'PyObject *'.
-The type 'PyObject' is a structure that only contains the reference count
-and the type pointer.  The actual memory allocated for an object
-contains other data that can only be accessed after casting the pointer
-to a pointer to a longer structure type.  This longer type must start
-with the reference count and type fields; the macro PyObject_HEAD should be
-used for this (to accommodate for future changes).  The implementation
-of a particular object type can cast the object pointer to the proper
-type and back.
-
-A standard interface exists for objects that contain an array of items
-whose size is determined when the object is allocated.

-More conventions
-================
-
-Argument Checking
------------------
-
-Functions that take objects as arguments normally don't check for nil
-arguments, but they do check the type of the argument, and return an
-error if the function doesn't apply to the type.
-
-Failure Modes
--------------
-
-Functions may fail for a variety of reasons, including running out of
-memory.  This is communicated to the caller in two ways: an error string
-is set (see errors.h), and the function result differs: functions that
-normally return a pointer return NULL for failure, functions returning
-an integer return -1 (which could be a legal return value too!), and
-other functions return 0 for success and -1 for failure.
-Callers should always check for errors before using the result.  If
-an error was set, the caller must either explicitly clear it, or pass
-the error on to its caller.
-
-Reference Counts
-----------------
-
-It takes a while to get used to the proper usage of reference counts.
-
-Functions that create an object set the reference count to 1; such new
-objects must be stored somewhere or destroyed again with Py_DECREF().
-Some functions that 'store' objects, such as PyTuple_SetItem() and
-PyList_SetItem(),
-don't increment the reference count of the object, since the most
-frequent use is to store a fresh object.  Functions that 'retrieve'
-objects, such as PyTuple_GetItem() and PyDict_GetItemString(), also
-don't increment
-the reference count, since most frequently the object is only looked at
-quickly.  Thus, to retrieve an object and store it again, the caller
-must call Py_INCREF() explicitly.
-
-NOTE: functions that 'consume' a reference count, like
-PyList_SetItem(), consume the reference even if the object wasn't
-successfully stored, to simplify error handling.
-
-It seems attractive to make other functions that take an object as
-argument consume a reference count; however, this may quickly get
-confusing (even the current practice is already confusing).  Consider
-it carefully, it may save lots of calls to Py_INCREF() and Py_DECREF() at
-times.

-Functions and macros for modules that implement new object types.
-
- - PyObject_New(type, typeobj) allocates memory for a new object of the given
-   type, and initializes part of it.  'type' must be the C structure type used
-   to represent the object, and 'typeobj' the address of the corresponding
-   type object.  Reference count and type pointer are filled in; the rest of
-   the bytes of the object are *undefined*!  The resulting expression type is
-   'type *'.  The size of the object is determined by the tp_basicsize field
-   of the type object.
-
- - PyObject_NewVar(type, typeobj, n) is similar but allocates a variable-size
-   object with room for n items.  In addition to the refcount and type pointer
-   fields, this also fills in the ob_size field.
-
- - PyObject_Del(op) releases the memory allocated for an object.  It does not
-   run a destructor -- it only frees the memory.  PyObject_Free is identical.
-
- - PyObject_Init(op, typeobj) and PyObject_InitVar(op, typeobj, n) don't
-   allocate memory.  Instead of a 'type' parameter, they take a pointer to a
-   new object (allocated by an arbitrary allocator), and initialize its object
-   header fields.
-
-Note that objects created with PyObject_{New, NewVar} are allocated using the
-specialized Python allocator (implemented in obmalloc.c), if WITH_PYMALLOC is
-enabled.  In addition, a special debugging allocator is used if PYMALLOC_DEBUG
-is also #defined.
-
-In case a specific form of memory management is needed (for example, if you
-must use the platform malloc heap(s), or shared memory, or C++ local storage or
-operator new), you must first allocate the object with your custom allocator,
-then pass its pointer to PyObject_{Init, InitVar} for filling in its Python-
-specific fields:  reference count, type pointer, possibly others.  You should
-be aware that Python has no control over these objects because they don't
-cooperate with the Python memory manager.  Such objects may not be eligible
-for automatic garbage collection and you have to make sure that they are
-released accordingly whenever their destructor gets called (cf. the specific
-form of memory management you're using).
-
-Unless you have specific memory management requirements, use
-PyObject_{New, NewVar, Del}.

- * Raw object memory interface

-
-/* Functions to call the same malloc/realloc/free as used by Python's

-   the platform malloc/realloc/free.  The Python object allocator is
-   designed for fast, cache-conscious allocation of many "small" objects,
-   and with low hidden memory overhead.
-
-   PyObject_Malloc(0) returns a unique non-NULL pointer if possible.
-
-   PyObject_Realloc(NULL, n) acts like PyObject_Malloc(n).
-   PyObject_Realloc(p != NULL, 0) does not return  NULL, or free the memory
-   at p.
-
-   Returned pointers must be checked for NULL explicitly; no action is
-   performed on failure other than to return NULL (no warning it printed, no
-   exception is set, etc).
-
-   For allocating objects, use PyObject_{New, NewVar} instead whenever
-   possible.  The PyObject_{Malloc, Realloc, Free} family is exposed
-   so that you can exploit Python's small-block allocator for non-object
-   uses.  If you must use these routines to allocate object memory, make sure
-   the object gets initialized via PyObject_{Init, InitVar} after obtaining
-   the raw memory.
