* PYTHON DIAMOND DEPENDENCY HEADER
*
* If your editor isn't able to automatically insert #include lines,
* then this header can make development easier. It's also great for
* making beginner's tutorials simpler and more attractive.
*
* However it's sloppy to use something like this in the long term since
* it's not a scalable dependency model. It makes builds slower, because
* changing any single header will invalidate all the build artifacts.
*
* So please consider doing the conscientious thing and avoid using it!

22-Feb-2006 MvL 1013 PEP 353 - long indices for sequence lengths
19-Aug-2002 GvR 1012 Changes to string object struct for
interning changes, saving 3 bytes.
17-Jul-2001 GvR 1011 Descr-branch, just to be on the safe side
25-Jan-2001 FLD 1010 Parameters added to PyCode_New() and
PyFrame_New(); Python 2.1a2
14-Mar-2000 GvR 1009 Unicode API added
3-Jan-1999 GvR 1007 Decided to change back! (Don't reuse 1008!)
3-Dec-1998 GvR 1008 Python 1.5.2b1
18-Jan-1997 GvR 1007 string interning and other speedups
11-Oct-1996 GvR renamed Py_Ellipses to Py_Ellipsis :-(
30-Jul-1996 GvR Slice and ellipses syntax added
23-Jul-1996 GvR For 1.4 -- better safe than sorry this time :-)
7-Nov-1995 GvR Keyword arguments (should've been done at 1.3 :-( )
10-Jan-1995 GvR Renamed globals to new naming scheme
9-Jan-1995 GvR Initial version (incompatible with older API)

/* BEWARE:
Each interface exports both functions and macros. Extension modules should
use the functions, to ensure binary compatibility across Python versions.
Because the Python implementation is free to change internal details, and
the macros may (or may not) expose details for speed, if you do use the
macros you must recompile your extensions with each Python release.
Never mix calls to PyMem_ with calls to the platform malloc/realloc/
calloc/free. For example, on Windows different DLLs may end up using
different heaps, and if you use PyMem_Malloc you'll get the memory from the
heap used by the Python DLL; it could be a disaster if you free()'ed that
directly in your own extension. Using PyMem_Free instead ensures Python
can return the memory to the proper heap. As another example, in
PYMALLOC_DEBUG mode, Python wraps all calls to all PyMem_ and PyObject_
memory functions in special debugging wrappers that add additional
debugging info to dynamic memory blocks. The system routines have no idea
what to do with that stuff, and the Python wrappers have no idea what to do
with raw blocks obtained directly by the system routines then.
The GIL must be held when using these APIs.

* So instead of holding the lock directly, the tstate holds a weakref to
* the lock: that's the value of on_delete_data below. Decref'ing a
* weakref is harmless.
* on_delete points to _threadmodule.c's static release_sentinel() function.

/* 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. */

/* 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.

The macros Py_INCREF(op) and Py_DECREF(op) are used to increment or decrement
reference counts. Py_DECREF calls the object's deallocator function when
the refcount falls to 0; for
objects that don't contain references to other objects or heap memory
this can be the standard function free(). Both macros can be used
wherever a void expression is allowed. The argument must not be a
NULL pointer. If it may be NULL, use Py_XINCREF/Py_XDECREF instead.
The macro _Py_NewReference(op) initialize reference counts to 1, and
in special builds (Py_REF_DEBUG, Py_TRACE_REFS) performs additional
bookkeeping appropriate to the special build.
We assume that the reference count field can never overflow; this can
be proven when the size of the field is the same as the pointer size, so
we ignore the possibility. Provided a C int is at least 32 bits (which
is implicitly assumed in many parts of this code), that's enough for
about 2**31 references to an object.
XXX The following became out of date in Python 2.2, but I'm not sure
XXX what the full truth is now. Certainly, heap-allocated type objects
XXX can and should be deallocated.
Type objects should never be deallocated; the type pointer in an object
is not considered to be a reference to the type object, to save
complications in the deallocation function. (This is actually a
decision that's up to the implementer of each new type so if you want,
you can count such references to the type object.)

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.
*/
/* 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 faults, and
especially in threads (which typically have less stack space to work with).
A container object that participates in cyclic gc 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_SAFE_BEGIN(p)
... The body of the deallocator goes here, including all calls ...
... to Py_DECREF on contained objects. ...
Py_TRASHCAN_SAFE_END(p)
}
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_SAFE_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 / PyTrash_UNWIND_LEVEL pieces,
with the call stack never exceeding a depth of PyTrash_UNWIND_LEVEL.

/* 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
for some observations.

/* 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
threads to run as follows:
...preparations here...
Py_BEGIN_ALLOW_THREADS
...blocking system call here...
Py_END_ALLOW_THREADS
...interpret result here...
The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a
{}-surrounded block.
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_BLOCK_THREADS
PyErr_SetFromErrno(PyExc_IOError);
return NULL;
}
An alternative is:
Py_BLOCK_THREADS
if (...premature_exit...) {
PyErr_SetFromErrno(PyExc_IOError);
return NULL;
}
Py_UNBLOCK_THREADS
For convenience, that the value of 'errno' is restored across
Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND
Py_END_ALLOW_THREADS!!!
The function PyEval_InitThreads() should be called only from
init_thread() in "_threadmodule.c".
Note that not yet all candidates have been converted to use this
mechanism!
