The basic idea is +that CPython counts how many different places there are that have a reference to an +object. Such a place could be another object, or a global (or static) C variable, or +a local variable in some C function. When an object’s reference count becomes zero, +the object is deallocated. If it contains references to other objects, their +reference counts are decremented. Those other objects may be deallocated in turn, if +this decrement makes their reference count become zero, and so on. The reference +count field can be examined using the ``sys.getrefcount()`` function (notice that the +value returned by this function is always 1 more as the function also has a reference +to the object when called): + +```pycon + >>> x = object() + >>> sys.getrefcount(x) + 2 + >>> y = x + >>> sys.getrefcount(x) + 3 + >>> del y + >>> sys.getrefcount(x) + 2 +``` + +The main problem with the reference counting scheme is that it does not handle reference +cycles. For instance, consider this code: + +```pycon + >>> container = [] + >>> container.append(container) + >>> sys.getrefcount(container) + 3 + >>> del container +``` + +In this example, ``container`` holds a reference to itself, so even when we remove +our reference to it (the variable "container") the reference count never falls to 0 +because it still has its own internal reference. Therefore it would never be +cleaned just by simple reference counting. For this reason some additional machinery +is needed to clean these reference cycles between objects once they become +unreachable. This is the cyclic garbage collector, usually called just Garbage +Collector (GC), even though reference counting is also a form of garbage collection. + +Starting in version 3.13, CPython contains two GC implementations: + +- The default build implementation relies on the + [global interpreter lock](https://docs.python.org/3/glossary.html#term-global-interpreter-lock) + for thread safety. +- The free-threaded build implementation pauses other executing threads when + performing a collection for thread safety. + +Both implementations use the same basic algorithms, but operate on different +data structures. The the section on +[Differences between GC implementations](#Differences-between-GC-implementations) +for the details. + + +Memory layout and object structure +================================== + +The garbage collector requires additional fields in Python objects to support +garbage collection. These extra fields are different in the default and the +free-threaded builds. + + +GC for the default build +------------------------ + +Normally the C structure supporting a regular Python object looks as follows: + +``` + object -----> +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ \ + | ob_refcnt | | + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | PyObject_HEAD + | *ob_type | | + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ / + | ... | +``` + +In order to support the garbage collector, the memory layout of objects is altered +to accommodate extra information **before** the normal layout: + +``` + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ \ + | *_gc_next | | + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | PyGC_Head + | *_gc_prev | | + object -----> +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ / + | ob_refcnt | \ + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | PyObject_HEAD + | *ob_type | | + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ / + | ... | +``` + + +In this way the object can be treated as a normal python object and when the extra +information associated to the GC is needed the previous fields can be accessed by a +simple type cast from the original object: `((PyGC_Head *)(the_object)-1)`. + +As is explained later in the +[Optimization: reusing fields to save memory](#optimization-reusing-fields-to-save-memory) +section, these two extra fields are normally used to keep doubly linked lists of all the +objects tracked by the garbage collector (these lists are the GC generations, more on +that in the [Optimization: generations](#Optimization-generations) section), but +they are also reused to fulfill other purposes when the full doubly linked list +structure is not needed as a memory optimization. + +Doubly linked lists are used because they efficiently support the most frequently required operations. In +general, the collection of all objects tracked by GC is partitioned into disjoint sets, each in its own +doubly linked list. Between collections, objects are partitioned into "generations", reflecting how +often they've survived collection attempts. During collections, the generation(s) being collected +are further partitioned into, for example, sets of reachable and unreachable objects. Doubly linked lists +support moving an object from one partition to another, adding a new object, removing an object +entirely (objects tracked by GC are most often reclaimed by the refcounting system when GC +isn't running at all!), and merging partitions, all with a small constant number of pointer updates. +With care, they also support iterating over a partition while objects are being added to - and +removed from - it, which is frequently required while GC is running. + +GC for the free-threaded build +------------------------------ + +In the free-threaded build, Python objects contain a 1-byte field +``ob_gc_bits`` that is used to track garbage collection related state. The +field exists in all objects, including ones that do not support cyclic +garbage collection. The field is used to identify objects that are tracked +by the collector, ensure that finalizers are called only once per object, +and, during garbage collection, differentiate reachable vs. unreachable objects. + +``` + object -----> +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ \ + | ob_tid | | + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | + | pad | ob_mutex | ob_gc_bits | ob_ref_local | | + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | PyObject_HEAD + | ob_ref_shared | | + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | + | *ob_type | | + +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ / + | ... | +``` + +Note that not all fields are to scale. ``pad`` is two bytes, ``ob_mutex`` and +``ob_gc_bits`` are each one byte, and ``ob_ref_local`` is four bytes. The +other fields, ``ob_tid``, ``ob_ref_shared``, and ``ob_type``, are all +pointer-sized (that is, eight bytes on a 64-bit platform). + + +The garbage collector also temporarily repurposes the ``ob_tid`` (thread ID) +and ``ob_ref_local`` (local reference count) fields for other purposes during +collections. + + +C APIs +------ + +Specific APIs are offered to allocate, deallocate, initialize, track, and untrack +objects with GC support. These APIs can be found in the +[Garbage Collector C API documentation](https://docs.python.org/3/c-api/gcsupport.html). + +Apart from this object structure, the type object for objects supporting garbage +collection must include the ``Py_TPFLAGS_HAVE_GC`` in its ``tp_flags`` slot and +provide an implementation of the ``tp_traverse`` handler. Unless it can be proven +that the objects cannot form reference cycles with only objects of its type or unless +the type is immutable, a ``tp_clear`` implementation must also be provided. + + +Identifying reference cycles +============================ + +The algorithm that CPython uses to detect those reference cycles is +implemented in the ``gc`` module. The garbage collector **only focuses** +on cleaning container objects (that is, objects that can contain a reference +to one or more objects). These can be arrays, dictionaries, lists, custom +class instances, classes in extension modules, etc. One could think that +cycles are uncommon but the truth is that many internal references needed by +the interpreter create cycles everywhere. Some notable examples: + +- Exceptions contain traceback objects that contain a list of frames that + contain the exception itself. +- Module-level functions reference the module's dict (which is needed to resolve globals), + which in turn contains entries for the module-level functions. +- Instances have references to their class which itself references its module, and the module + contains references to everything that is inside (and maybe other modules) + and this can lead back to the original instance. +- When representing data structures like graphs, it is very typical for them to + have internal links to themselves. + +To correctly dispose of these objects once they become unreachable, they need +to be identified first. To understand how the algorithm works, let’s take +the case of a circular linked list which has one link referenced by a +variable ``A``, and one self-referencing object which is completely +unreachable: + +```pycon + >>> import gc + + >>> class Link: + ... def __init__(self, next_link=None): + ... self.next_link = next_link + + >>> link_3 = Link() + >>> link_2 = Link(link_3) + >>> link_1 = Link(link_2) + >>> link_3.next_link = link_1 + >>> A = link_1 + >>> del link_1, link_2, link_3 + + >>> link_4 = Link() + >>> link_4.next_link = link_4 + >>> del link_4 + + # Collect the unreachable Link object (and its .__dict__ dict). + >>> gc.collect() + 2 +``` + +The GC starts with a set of candidate objects it wants to scan. In the +default build, these "objects to scan" might be all container objects or a +smaller subset (or "generation"). In the free-threaded build, the collector +always scans all container objects. + +The objective is to identify all the unreachable objects. The collector does +this by identifying reachable objects; the remaining objects must be +unreachable. The first step is to identify all of the "to scan" objects that +are **directly** reachable from outside the set of candidate objects. These +objects have a refcount larger than the number of incoming references from +within the candidate set. + +Every object that supports garbage collection will have an extra reference +count field initialized to the reference count (``gc_ref`` in the figures) +of that object when the algorithm starts. This is because the algorithm needs +to modify the reference count to do the computations and in this way the +interpreter will not modify the real reference count field. + +![gc-image1](images/python-cyclic-gc-1-new-page.png) + +The GC then iterates over all containers in the first list and decrements by one the +`gc_ref` field of any other object that container is referencing. Doing +this makes use of the ``tp_traverse`` slot in the container class (implemented +using the C API or inherited by a superclass) to know what objects are referenced by +each container. After all the objects have been scanned, only the objects that have +references from outside the “objects to scan” list will have ``gc_ref > 0``. + +![gc-image2](images/python-cyclic-gc-2-new-page.png) + +Notice that having ``gc_ref == 0`` does not imply that the object is unreachable. +This is because another object that is reachable from the outside (``gc_ref > 0``) +can still have references to it. For instance, the ``link_2`` object in our example +ended having ``gc_ref == 0`` but is referenced still by the ``link_1`` object that +is reachable from the outside. To obtain the set of objects that are really +unreachable, the garbage collector re-scans the container objects using the +``tp_traverse`` slot; this time with a different traverse function that marks objects with +``gc_ref == 0`` as "tentatively unreachable" and then moves them to the +tentatively unreachable list. The following image depicts the state of the lists in a +moment when the GC processed the ``link_3`` and ``link_4`` objects but has not +processed ``link_1`` and ``link_2`` yet. + +![gc-image3](images/python-cyclic-gc-3-new-page.png) + +Then the GC scans the next ``link_1`` object. Because it has ``gc_ref == 1``, +the gc does not do anything special because it knows it has to be reachable (and is +already in what will become the reachable list): + +![gc-image4](images/python-cyclic-gc-4-new-page.png) + +When the GC encounters an object which is reachable (``gc_ref > 0``), it traverses +its references using the ``tp_traverse`` slot to find all the objects that are +reachable from it, moving them to the end of the list of reachable objects (where +they started originally) and setting its ``gc_ref`` field to 1. This is what happens +to ``link_2`` and ``link_3`` below as they are reachable from ``link_1``. From the +state in the previous image and after examining the objects referred to by ``link_1`` +the GC knows that ``link_3`` is reachable after all, so it is moved back to the +original list and its ``gc_ref`` field is set to 1 so that if the GC visits it again, +it will know that it's reachable. To avoid visiting an object twice, the GC marks all +objects that have already been visited once (by unsetting the ``PREV_MASK_COLLECTING`` +flag) so that if an object that has already been processed is referenced by some other +object, the GC does not process it twice. + +![gc-image5](images/python-cyclic-gc-5-new-page.png) + +Notice that an object that was marked as "tentatively unreachable" and was later +moved back to the reachable list will be visited again by the garbage collector +as now all the references that that object has need to be processed as well. This +process is really a breadth first search over the object graph. Once all the objects +are scanned, the GC knows that all container objects in the tentatively unreachable +list are really unreachable and can thus be garbage collected. + +Pragmatically, it's important to note that no recursion is required by any of this, +and neither does it in any other way require additional memory proportional to the +number of objects, number of pointers, or the lengths of pointer chains. Apart from +``O(1)`` storage for internal C needs, the objects themselves contain all the storage +the GC algorithms require. + +Why moving unreachable objects is better +---------------------------------------- + +It sounds logical to move the unreachable objects under the premise that most objects +are usually reachable, until you think about it: the reason it pays isn't actually +obvious. + +Suppose we create objects A, B, C in that order. They appear in the young generation +in the same order. If B points to A, and C to B, and C is reachable from outside, +then the adjusted refcounts after the first step of the algorithm runs will be 0, 0, +and 1 respectively because the only reachable object from the outside is C. + +When the next step of the algorithm finds A, A is moved to the unreachable list. The +same for B when it's first encountered. Then C is traversed, B is moved *back* to +the reachable list. B is eventually traversed, and then A is moved back to the reachable +list. + +So instead of not moving at all, the reachable objects B and A are each moved twice. +Why is this a win? A straightforward algorithm to move the reachable objects instead +would move A, B, and C once each. The key is that this dance leaves the objects in +order C, B, A - it's reversed from the original order. On all *subsequent* scans, +none of them will move. Since most objects aren't in cycles, this can save an +unbounded number of moves across an unbounded number of later collections. The only +time the cost can be higher is the first time the chain is scanned. + +Destroying unreachable objects +============================== + +Once the GC knows the list of unreachable objects, a very delicate process starts +with the objective of completely destroying these objects. Roughly, the process +follows these steps in order: + +1. Handle and clear weak references (if any). Weak references to unreachable objects + are set to ``None``. If the weak reference has an associated callback, the callback + is enqueued to be called once the clearing of weak references is finished. We only + invoke callbacks for weak references that are themselves reachable. If both the weak + reference and the pointed-to object are unreachable we do not execute the callback. + This is partly for historical reasons: the callback could resurrect an unreachable + object and support for weak references predates support for object resurrection. + Ignoring the weak reference's callback is fine because both the object and the weakref + are going away, so it's legitimate to say the weak reference is going away first. +2. If an object has legacy finalizers (``tp_del`` slot) move it to the + ``gc.garbage`` list. +3. Call the finalizers (``tp_finalize`` slot) and mark the objects as already + finalized to avoid calling finalizers twice if the objects are resurrected or + if other finalizers have removed the object first. +4. Deal with resurrected objects. If some objects have been resurrected, the GC + finds the new subset of objects that are still unreachable by running the cycle + detection algorithm again and continues with them. +5. Call the ``tp_clear`` slot of every object so all internal links are broken and + the reference counts fall to 0, triggering the destruction of all unreachable + objects. + +Optimization: generations +========================= + +In order to limit the time each garbage collection takes, the GC +implementation for the default build uses a popular optimization: +generations. The main idea behind this concept is the assumption that most +objects have a very short lifespan and can thus be collected soon after their +creation. This has proven to be very close to the reality of many Python +programs as many temporary objects are created and destroyed very quickly. + +To take advantage of this fact, all container objects are segregated into +three spaces/generations. Every new +object starts in the first generation (generation 0). The previous algorithm is +executed only over the objects of a particular generation and if an object +survives a collection of its generation it will be moved to the next one +(generation 1), where it will be surveyed for collection less often. If +the same object survives another GC round in this new generation (generation 1) +it will be moved to the last generation (generation 2) where it will be +surveyed the least often. + +The GC implementation for the free-threaded build does not use multiple +generations. Every collection operates on the entire heap. + +In order to decide when to run, the collector keeps track of the number of object +allocations and deallocations since the last collection. When the number of +allocations minus the number of deallocations exceeds ``threshold_0``, +collection starts. Initially only generation 0 is examined. If generation 0 has +been examined more than ``threshold_1`` times since generation 1 has been +examined, then generation 1 is examined as well. With generation 2, +things are a bit more complicated; see +[Collecting the oldest generation](#Collecting-the-oldest-generation) for +more information. These thresholds can be examined using the +[`gc.get_threshold()`](https://docs.python.org/3/library/gc.html#gc.get_threshold) +function: + +```pycon + >>> import gc + >>> gc.get_threshold() + (700, 10, 10) +``` + +The content of these generations can be examined using the +``gc.get_objects(generation=NUM)`` function and collections can be triggered +specifically in a generation by calling ``gc.collect(generation=NUM)``. + +```pycon + >>> import gc + >>> class MyObj: + ... pass + ... + + # Move everything to the last generation so it's easier to inspect + # the younger generations. + + >>> gc.collect() + 0 + + # Create a reference cycle. + + >>> x = MyObj() + >>> x.self = x + + # Initially the object is in the youngest generation. + + >>> gc.get_objects(generation=0) + [..., <__main__.MyObj object at 0x7fbcc12a3400>, ...] + + # After a collection of the youngest generation the object + # moves to the next generation. + + >>> gc.collect(generation=0) + 0 + >>> gc.get_objects(generation=0) + [] + >>> gc.get_objects(generation=1) + [..., <__main__.MyObj object at 0x7fbcc12a3400>, ...] +``` + +Collecting the oldest generation +-------------------------------- + +In addition to the various configurable thresholds, the GC only triggers a full +collection of the oldest generation 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 (that is, 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 of object +creations entails a dramatic performance degradation in workloads which consist +of creating and storing lots of long-lived objects (for example, building a large list +of GC-tracked objects would show quadratic performance, instead of linear as +expected). 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"). + +Optimization: reusing fields to save memory +=========================================== + +In order to save memory, the two linked list pointers in every object with GC +support are reused for several purposes. This is a common optimization known +as "fat pointers" or "tagged pointers": pointers that carry additional data, +"folded" into the pointer, meaning stored inline in the data representing the +address, taking advantage of certain properties of memory addressing. This is +possible as most architectures align certain types of data +to the size of the data, often a word or multiple thereof. This discrepancy +leaves a few of the least significant bits of the pointer unused, which can be +used for tags or to keep other information – most often as a bit field (each +bit a separate tag) – as long as code that uses the pointer masks out these +bits before accessing memory. For example, on a 32-bit architecture (for both +addresses and word size), a word is 32 bits = 4 bytes, so word-aligned +addresses are always a multiple of 4, hence end in ``00``, leaving the last 2 bits +available; while on a 64-bit architecture, a word is 64 bits = 8 bytes, so +word-aligned addresses end in ``000``, leaving the last 3 bits available. + +The CPython GC makes use of two fat pointers that correspond to the extra fields +of ``PyGC_Head`` discussed in the `Memory layout and object structure`_ section: + +> [!WARNING] +> Because the presence of extra information, "tagged" or "fat" pointers cannot be +> dereferenced directly and the extra information must be stripped off before +> obtaining the real memory address. Special care needs to be taken with +> functions that directly manipulate the linked lists, as these functions +> normally assume the pointers inside the lists are in a consistent state. + + +- The ``_gc_prev`` field is normally used as the "previous" pointer to maintain the + doubly linked list but its lowest two bits are used to keep the flags + ``PREV_MASK_COLLECTING`` and ``_PyGC_PREV_MASK_FINALIZED``. Between collections, + the only flag that can be present is ``_PyGC_PREV_MASK_FINALIZED`` that indicates + if an object has been already finalized. During collections ``_gc_prev`` is + temporarily used for storing a copy of the reference count (``gc_ref``), in + addition to two flags, and the GC linked list becomes a singly linked list until + ``_gc_prev`` is restored. + +- The ``_gc_next`` field is used as the "next" pointer to maintain the doubly linked + list but during collection its lowest bit is used to keep the + ``NEXT_MASK_UNREACHABLE`` flag that indicates if an object is tentatively + unreachable during the cycle detection algorithm. This is a drawback to using only + doubly linked lists to implement partitions: while most needed operations are + constant-time, there is no efficient way to determine which partition an object is + currently in. Instead, when that's needed, ad hoc tricks (like the + ``NEXT_MASK_UNREACHABLE`` flag) are employed. + +Optimization: delay tracking containers +======================================= + +Certain types of containers 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 collection. 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: + +1. When the container is created. +2. When the container is examined by the garbage collector. + +As a general rule, instances of atomic types aren't tracked and instances of +non-atomic types (containers, user-defined objects...) are. However, some +type-specific optimizations can be present in order to suppress the garbage +collector footprint of simple instances. Some examples of native types that +benefit from delayed tracking: + +- 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 garbage collector 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. + +```pycon + >>> gc.is_tracked(0) + False + >>> gc.is_tracked("a") + False + >>> gc.is_tracked([]) + True + >>> gc.is_tracked({}) + False + >>> gc.is_tracked({"a": 1}) + False + >>> gc.is_tracked({"a": []}) + True +``` + +Differences between GC implementations +====================================== + +This section summarizes the differences between the GC implementation in the +default build and the implementation in the free-threaded build. + +The default build implementation makes extensive use of the ``PyGC_Head`` data +structure, while the free-threaded build implementation does not use that +data structure. + +- The default build implementation stores all tracked objects in a doubly + linked list using ``PyGC_Head``. The free-threaded build implementation + instead relies on the embedded mimalloc memory allocator to scan the heap + for tracked objects. +- The default build implementation uses ``PyGC_Head`` for the unreachable + object list. The free-threaded build implementation repurposes the + ``ob_tid`` field to store a unreachable objects linked list. +- The default build implementation stores flags in the ``_gc_prev`` field of + ``PyGC_Head``. The free-threaded build implementation stores these flags + in ``ob_gc_bits``. + + +The default build implementation relies on the +[global interpreter lock](https://docs.python.org/3/glossary.html#term-global-interpreter-lock) +for thread safety. The free-threaded build implementation has two "stop the +world" pauses, in which all other executing threads are temporarily paused so +that the GC can safely access reference counts and object attributes. + +The default build implementation is a generational collector.
