/* 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

threads to run as follows:

Py_BEGIN_ALLOW_THREADS

Py_END_ALLOW_THREADS

The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a

a line containing Py_BLOCK_THREADS before the return, e.g.
if (...premature_exit...) {

}
An alternative is:
Py_BLOCK_THREADS
if (...premature_exit...) {

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

/* 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,
using conditional critical sections (Await/LockWhen) and when constructing
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);
PutElementIntoMyQueue(e);
}
Type *MyQueue::Get() {
MutexLock lock(&mu_);
Type *e = GetElementFromMyQueue();
_Py_ANNOTATE_HAPPENS_AFTER(e);
return e;
}
Note: when possible, please use the existing reference counting and message
queue implementations instead of inventing new ones. */

* routines produce a C double from such a string. The suffix (4 or 8)
* specifies the number of bytes in the string.
*
* On platforms that appear to use (see _PyFloat_Init()) IEEE-754 formats
* these functions work by copying bits. On other platforms, the formats the
* 4- byte format is identical to the IEEE-754 single precision format, and
* 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
* 754 supports, not all values can be packed; on non-IEEE platforms with less
* precision, or smaller dynamic range, not all values can be unpacked. What
* happens in such cases is partly accidental (alas).

* first, at p).
* Return value: 0 if all is OK, -1 if error (and an exception is
* set, most likely OverflowError).

condition between releasing the outer lock and waiting) because it
maintains state even though a wait hasn't happened, there is still
a lost wakeup problem if more than one thread are interrupted in the

counted, not Boolean.

/*
NOTE: about the counting of long-lived objects.
To limit the cost of garbage collection, there are two strategies;
- make each collection faster, e.g. by scanning fewer objects
- do less collections
This heuristic is about the latter strategy.
In addition to the various configurable thresholds, we only trigger a
full collection if the ratio
long_lived_pending / long_lived_total
is above a given value (hardwired to 25%).
The reason is that, while "non-full" collections (i.e., collections of
the young and middle generations) will always examine roughly the same
number of objects -- determined by the aforementioned thresholds --,
the cost of a full collection is proportional to the total number of
long-lived objects, which is virtually unbounded.
Indeed, it has been remarked that doing a full collection every
<constant number> of object creations entails a dramatic performance
degradation in workloads which consist in creating and storing lots of
long-lived objects (e.g. building a large list of GC-tracked objects would
show quadratic performance, instead of linear as expected: see issue #4074).
Using the above ratio, instead, yields amortized linear performance in
the total number of objects (the effect of which can be summarized
thusly: "each full garbage collection is more and more costly as the
number of objects grows, but we do fewer and fewer of them").
This heuristic was suggested by Martin von Löwis on python-dev in
June 2008. His original analysis and proposal can be found at:
http://mail.python.org/pipermail/python-dev/2008-June/080579.html
*/
/*
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.

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

*/
/*
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
object allocator. If WITH_PYMALLOC is enabled, these may differ from
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.

XXX no longer valid? (That's clearly true, but not sure that's what
XXX the text is trying to say.)
PyArena_New() returns an arena pointer. On error, it
returns a negative number and sets an exception.
XXX (tim): Not true. On error, PyArena_New() actually returns NULL,
XXX and looks like it may or may not set an exception (e.g., if the
XXX internal PyList_New(0) returns NULL, PyArena_New() passes that on
XXX and an exception is set; OTOH, if the internal
XXX block_new(DEFAULT_BLOCK_SIZE) returns NULL, that's passed on but
XXX an exception is not set in that case).

#define _PYGAME_H
/** This header file includes all the definitions for the
** base pygame extensions. This header only requires
** SDL and Python includes. The reason for functions
** prototyped with #define's is to allow for maximum
** python portability. It also uses python as the
** runtime linker, which allows for late binding. For more
** information on this style of development, read the Python
** docs on this subject.
** http://www.python.org/doc/current/ext/using-cobjects.html
**
** If using this to build your own derived extensions,
** you'll see that the functions available here are mainly
** used to help convert between python objects and SDL objects.
** Since this library doesn't add a lot of functionality to
** the SDL libarary, it doesn't need to offer a lot either.
**
** When initializing your extension module, you must manually
** import the modules you want to use. (this is the part about
** using python as the runtime linker). Each module has its
** own import_xxx() routine. You need to perform this import
** after you have initialized your own module, and before
** you call any routines from that module. Since every module
** in pygame does this, there are plenty of examples.
**
** The base module does include some useful conversion routines
** that you are free to use in your own extension.
**
** When making changes, it is very important to keep the
** FIRSTSLOT and NUMSLOT constants up to date for each
** section. Also be sure not to overlap any of the slots.
** When you do make a mistake with this, it will result
** is a dereferenced NULL pointer that is easier to diagnose
** than it could be :]
