+/* 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. */

+ 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

+/*
+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.
+*/
+
+
+/* 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().

+ 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

+
+ - 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).
