/*
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_Free(op) releases the memory allocated for an object. It does not
run a destructor -- it only frees the memory.
- 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 Py_DEBUG
macro 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.

/* 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.

Immortalization:
The following indicates the immortalization strategy depending on the amount

Proper deallocation of immortal instances requires distinguishing between
statically allocated immortal instances vs those promoted by the runtime to be
immortal. The latter should be the only instances that require
cleanup during runtime finalization.

increase and decrease the objects reference count. The object would lose its
immortality, but the execution would still be correct.
Reference count increases will use saturated arithmetic, taking advantage of
having all the lower 32 bits set, which will avoid the reference count to go
beyond the refcount limit. Immortality checks for reference count decreases will
be done by checking the bit sign flag in the lower 32 bits.

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.)

/* Safely decref `op` and set `op` to NULL, especially useful in tp_clear
* and tp_dealloc implementations.
*
* Note that "the obvious" code can be deadly:
*
* Py_XDECREF(op);
* op = NULL;
*
* Typically, `op` is something like self->containee, and `self` is done
* using its `containee` member. In the code sequence above, suppose
* `containee` is non-NULL with a refcount of 1. Its refcount falls to
* 0 on the first line, which can trigger an arbitrary amount of code,
* possibly including finalizers (like __del__ methods or weakref callbacks)
* coded in Python, which in turn can release the GIL and allow other threads
* to run, etc. Such code may even invoke methods of `self` again, or cause
* cyclic gc to trigger, but-- oops! --self->containee still points to the
* object being torn down, and it may be in an insane state while being torn
* down. This has in fact been a rich historic source of miserable (rare &
* hard-to-diagnose) segfaulting (and other) bugs.
*
* The safe way is:
*
* Py_CLEAR(op);
*
* That arranges to set `op` to NULL _before_ decref'ing, so that any code
* triggered as a side-effect of `op` getting torn down no longer believes
* `op` points to a valid object.
*
* There are cases where it's safe to use the naive code, but they're brittle.
* For example, if `op` points to a Python integer, you know that destroying
* one of those can't cause problems -- but in part that relies on that
* Python integers aren't currently weakly referencable. Best practice is
* to use Py_CLEAR() even if you can't think of a reason for why you need to.
*
* gh-98724: Use a temporary variable to only evaluate the macro argument once,
* to avoid the duplication of side effects if the argument has side effects.
*
* gh-99701: If the PyObject* type is used with casting arguments to PyObject*,
* the code can be miscompiled with strict aliasing because of type punning.
* With strict aliasing, a compiler considers that two pointers of different
* types cannot read or write the same memory which enables optimization
* opportunities.
*
* If available, use _Py_TYPEOF() to use the 'op' type for temporary variables,
* and so avoid type punning. Otherwise, use memcpy() which causes type erasure
* and so prevents the compiler to reuse an old cached 'op' value after
* Py_CLEAR().

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.

/* An object allocator for Python.
Here is an introduction to the layers of the Python memory architecture,
showing where the object allocator is actually used (layer +2), It is
called for every object allocation and deallocation (PyObject_New/Del),
unless the object-specific allocators implement a proprietary allocation
scheme (ex.: ints use a simple free list). This is also the place where
the cyclic garbage collector operates selectively on container objects.

* Allocation strategy abstract:
*
* For small requests, the allocator sub-allocates <Big> blocks of memory.
* Requests greater than SMALL_REQUEST_THRESHOLD bytes are routed to the
* system's allocator.
*
* Small requests are grouped in size classes spaced 8 bytes apart, due
* to the required valid alignment of the returned address. Requests of
* a particular size are serviced from memory pools of 4K (one VMM page).
* Pools are fragmented on demand and contain free lists of blocks of one
* particular size class. In other words, there is a fixed-size allocator
* for each size class. Free pools are shared by the different allocators
* thus minimizing the space reserved for a particular size class.
*
* This allocation strategy is a variant of what is known as "simple
* segregated storage based on array of free lists". The main drawback of
* simple segregated storage is that we might end up with lot of reserved
* memory for the different free lists, which degenerate in time. To avoid
* this, we partition each free list in pools and we share dynamically the
* reserved space between all free lists. This technique is quite efficient
* for memory intensive programs which allocate mainly small-sized blocks.
*
* For small requests we have the following table:
*
* Request in bytes Size of allocated block Size class idx
* ----------------------------------------------------------------
* 1-8 8 0
* 9-16 16 1
* 17-24 24 2

/*
* Pool table -- headed, circular, doubly-linked lists of partially used pools.
This is involved. For an index i, usedpools[i+i] is the header for a list of
all partially used pools holding small blocks with "size class idx" i. So
usedpools[0] corresponds to blocks of size 8, usedpools[2] to blocks of size
16, and so on: index 2*i <-> blocks of size (i+1)<<ALIGNMENT_SHIFT.
Pools are carved off an arena's highwater mark (an arena_object's pool_address
member) as needed. Once carved off, a pool is in one of three states forever
after:
used == partially used, neither empty nor full
At least one block in the pool is currently allocated, and at least one
block in the pool is not currently allocated (note this implies a pool
has room for at least two blocks).
This is a pool's initial state, as a pool is created only when malloc
needs space.
The pool holds blocks of a fixed size, and is in the circular list headed
at usedpools[i] (see above). It's linked to the other used pools of the
same size class via the pool_header's nextpool and prevpool members.
If all but one block is currently allocated, a malloc can cause a
transition to the full state. If all but one block is not currently
allocated, a free can cause a transition to the empty state.
full == all the pool's blocks are currently allocated
On transition to full, a pool is unlinked from its usedpools[] list.
It's not linked to from anything then anymore, and its nextpool and
prevpool members are meaningless until it transitions back to used.
A free of a block in a full pool puts the pool back in the used state.
Then it's linked in at the front of the appropriate usedpools[] list, so
that the next allocation for its size class will reuse the freed block.
empty == all the pool's blocks are currently available for allocation
On transition to empty, a pool is unlinked from its usedpools[] list,
and linked to the front of its arena_object's singly-linked freepools list,
via its nextpool member. The prevpool member has no meaning in this case.
Empty pools have no inherent size class: the next time a malloc finds
an empty list in usedpools[], it takes the first pool off of freepools.
If the size class needed happens to be the same as the size class the pool
last had, some pool initialization can be skipped.
Block Management
Blocks within pools are again carved out as needed. pool->freeblock points to
the start of a singly-linked list of free blocks within the pool. When a
block is freed, it's inserted at the front of its pool's freeblock list. Note
that the available blocks in a pool are *not* linked all together when a pool
is initialized. Instead only "the first two" (lowest addresses) blocks are
set up, returning the first such block, and setting pool->freeblock to a
one-block list holding the second such block. This is consistent with that
pymalloc strives at all levels (arena, pool, and block) never to touch a piece
of memory until it's actually needed.
So long as a pool is in the used state, we're certain there *is* a block
available for allocating, and pool->freeblock is not NULL. If pool->freeblock
points to the end of the free list before we've carved the entire pool into
blocks, that means we simply haven't yet gotten to one of the higher-address
blocks. The offset from the pool_header to the start of "the next" virgin
block is stored in the pool_header nextoffset member, and the largest value
of nextoffset that makes sense is stored in the maxnextoffset member when a
pool is initialized. All the blocks in a pool have been passed out at least
once when and only when nextoffset > maxnextoffset.
Major obscurity: While the usedpools vector is declared to have poolp
entries, it doesn't really. It really contains two pointers per (conceptual)
poolp entry, the nextpool and prevpool members of a pool_header. The
excruciating initialization code below fools C so that
usedpool[i+i]
"acts like" a genuine poolp, but only so long as you only reference its
nextpool and prevpool members. The "- 2*sizeof(pymem_block *)" gibberish is
compensating for that a pool_header's nextpool and prevpool members
immediately follow a pool_header's first two members:
union { pymem_block *_padding;
uint count; } ref;
pymem_block *freeblock;
each of which consume sizeof(pymem_block *) bytes. So what usedpools[i+i] really
contains is a fudged-up pointer p such that *if* C believes it's a poolp
pointer, then p->nextpool and p->prevpool are both p (meaning that the headed
circular list is empty).
It's unclear why the usedpools setup is so convoluted. It could be to
minimize the amount of cache required to hold this heavily-referenced table
(which only *needs* the two interpool pointer members of a pool_header). OTOH,
referencing code has to remember to "double the index" and doing so isn't
free, usedpools[0] isn't a strictly legal pointer, and we're crucially relying
on that C doesn't insert any padding anywhere in a pool_header at or before
the prevpool member.

Arena management.
`arenas` is a vector of arena_objects. It contains maxarenas entries, some of
which may not be currently used (== they're arena_objects that aren't
currently associated with an allocated arena). Note that arenas proper are
separately malloc'ed.
Prior to Python 2.5, arenas were never free()'ed. Starting with Python 2.5,
we do try to free() arenas, and use some mild heuristic strategies to increase
the likelihood that arenas eventually can be freed.
unused_arena_objects
This is a singly-linked list of the arena_objects that are currently not
being used (no arena is associated with them). Objects are taken off the
head of the list in new_arena(), and are pushed on the head of the list in
PyObject_Free() when the arena is empty. Key invariant: an arena_object
is on this list if and only if its .address member is 0.
usable_arenas
This is a doubly-linked list of the arena_objects associated with arenas
that have pools available. These pools are either waiting to be reused,
or have not been used before. The list is sorted to have the most-
allocated arenas first (ascending order based on the nfreepools member).
This means that the next allocation will come from a heavily used arena,
which gives the nearly empty arenas a chance to be returned to the system.
In my unscientific tests this dramatically improved the number of arenas
that could be freed.
Note that an arena_object associated with an arena all of whose pools are
currently in use isn't on either list.
Changed in Python 3.8: keeping usable_arenas sorted by number of free pools
used to be done by one-at-a-time linear search when an arena's number of
free pools changed. That could, overall, consume time quadratic in the
number of arenas. That didn't really matter when there were only a few
hundred arenas (typical!), but could be a timing disaster when there were
hundreds of thousands. See bpo-37029.
Now we have a vector of "search fingers" to eliminate the need to search:
nfp2lasta[nfp] returns the last ("rightmost") arena in usable_arenas
with nfp free pools. This is NULL if and only if there is no arena with
nfp free pools in usable_arenas.

The thread local default heap: `_mi_prim_get_default_heap()`
This is inlined here as it is on the fast path for allocation functions.
On most platforms (Windows, Linux, FreeBSD, NetBSD, etc), this just returns a
__thread local variable (`_mi_heap_default`). With the initial-exec TLS model this ensures
that the storage will always be available (allocated on the thread stacks).
On some platforms though we cannot use that when overriding `malloc` since the underlying
TLS implementation (or the loader) will call itself `malloc` on a first access and recurse.
We try to circumvent this in an efficient way:
- macOSX : we use an unused TLS slot from the OS allocated slots (MI_TLS_SLOT). On OSX, the
loader itself calls `malloc` even before the modules are initialized.
- OpenBSD: we use an unused slot from the pthread block (MI_TLS_PTHREAD_SLOT_OFS).
- DragonFly: defaults are working but seem slow compared to freeBSD (see PR #323)

#ifndef MIMALLOC_TRACK_H
#define MIMALLOC_TRACK_H
/* ------------------------------------------------------------------------------------------------------
Track memory ranges with macros for tools like Valgrind address sanitizer, or other memory checkers.
These can be defined for tracking allocation:
#define mi_track_malloc_size(p,reqsize,size,zero)
#define mi_track_free_size(p,_size)
The macros are set up such that the size passed to `mi_track_free_size`
always matches the size of `mi_track_malloc_size`. (currently, `size == mi_usable_size(p)`).
The `reqsize` is what the user requested, and `size >= reqsize`.
The `size` is either byte precise (and `size==reqsize`) if `MI_PADDING` is enabled,
or otherwise it is the usable block size which may be larger than the original request.
Use `_mi_block_size_of(void* p)` to get the full block size that was allocated (including padding etc).
The `zero` parameter is `true` if the allocated block is zero initialized.
Optional:
#define mi_track_align(p,alignedp,offset,size)
#define mi_track_resize(p,oldsize,newsize)
#define mi_track_init()
The `mi_track_align` is called right after a `mi_track_malloc` for aligned pointers in a block.
The corresponding `mi_track_free` still uses the block start pointer and original size (corresponding to the `mi_track_malloc`).
The `mi_track_resize` is currently unused but could be called on reallocations within a block.
`mi_track_init` is called at program start.
The following macros are for tools like asan and valgrind to track whether memory is
defined, undefined, or not accessible at all:

#define mi_track_mem_undefined(p,size)
#define mi_track_mem_noaccess(p,size)

Encoding/Decoding the free list next pointers
This is to protect against buffer overflow exploits where the
free list is mutated. Many hardened allocators xor the next pointer `p`
with a secret key `k1`, as `p^k1`. This prevents overwriting with known
values but might be still too weak: if the attacker can guess
the pointer `p` this can reveal `k1` (since `p^k1^p == k1`).
Moreover, if multiple blocks can be read as well, the attacker can
xor both as `(p1^k1) ^ (p2^k1) == p1^p2` which may reveal a lot
about the pointers (and subsequently `k1`).
Instead mimalloc uses an extra key `k2` and encodes as `((p^k2)<<<k1)+k1`.
Since these operations are not associative, the above approaches do not
work so well any more even if the `p` can be guesstimated. For example,
for the read case we can subtract two entries to discard the `+k1` term,
but that leads to `((p1^k2)<<<k1) - ((p2^k2)<<<k1)` at best.
We include the left-rotation since xor and addition are otherwise linear
in the lowest bit. Finally, both keys are unique per page which reduces
the re-use of keys by a large factor.
We also pass a separate `null` value to be used as `NULL` or otherwise
`(k2<<<k1)+k1` would appear (too) often as a sentinel value.

Semaphores are available on Windows XP (2003 server) and later.
We use a Semaphore rather than an auto-reset event, because although
an auto-reset event might appear to solve the lost-wakeup bug (race
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
critical place. A semaphore solves that, because its state is
counted, not Boolean.
Because it is ok to signal a condition variable with no one
waiting, we need to keep track of the number of
waiting threads. Otherwise, the semaphore's state could rise
without bound. This also helps reduce the number of "spurious wakeups"
that would otherwise happen.

* Caution:
* This isn't reliable. C99 no longer requires libm to set errno under
* any exceptional condition, but does require +- HUGE_VAL return
* values on overflow. A 754 box *probably* maps HUGE_VAL to a
* double infinity, and we're cool if that's so, unless the input
* was an infinity and an infinity is the expected result. A C89
* system sets errno to ERANGE, so we check for that too. We're
* out of luck if a C99 754 box doesn't map HUGE_VAL to +Inf, or

//--- HAVE_PY_SET_53BIT_PRECISION macro ------------------------------------
//
// The functions _Py_dg_strtod() and _Py_dg_dtoa() in Python/dtoa.c (which are
// required to support the short float repr introduced in Python 3.1) require
// that the floating-point unit that's being used for arithmetic operations on
// C doubles is set to use 53-bit precision. It also requires that the FPU
// rounding mode is round-half-to-even, but that's less often an issue.
//
// If your FPU isn't already set to 53-bit precision/round-half-to-even, and
// you want to make use of _Py_dg_strtod() and _Py_dg_dtoa(), then you should:
//
// #define HAVE_PY_SET_53BIT_PRECISION 1
//
// and also give appropriate definitions for the following three macros:
//
// * _Py_SET_53BIT_PRECISION_HEADER: any variable declarations needed to
// use the two macros below.
// * _Py_SET_53BIT_PRECISION_START: store original FPU settings, and
// set FPU to 53-bit precision/round-half-to-even
// * _Py_SET_53BIT_PRECISION_END: restore original FPU settings
//
// The macros are designed to be used within a single C function: see
// Python/pystrtod.c for an example of their use.

* the original pointer. If a converted pointer is used to call a function
* whose type is not compatible with the pointed-to type, the behavior is

*
* Typical native ABIs ignore additional arguments or fill in missing values

*
* Bad fpcasts are an issue in WebAssembly. WASM's indirect_call has strict

_BlocksOutputBuffer is used to maintain an output buffer

stream->next_out: point to the next output position.
stream->avail_out: the number of available bytes left in the buffer.
It maintains a list of bytes object, so there is no overhead of resizing
the buffer.
Usage:
1, Initialize the struct instance like this:
_BlocksOutputBuffer buffer = {.list = NULL};
Set .list to NULL for _BlocksOutputBuffer_OnError()
2, Initialize the buffer use one of these functions:
_BlocksOutputBuffer_InitAndGrow()
_BlocksOutputBuffer_InitWithSize()
3, If (avail_out == 0), grow the buffer:
_BlocksOutputBuffer_Grow()
4, Get the current outputted data size:
_BlocksOutputBuffer_GetDataSize()
5, Finish the buffer, and return a bytes object:
_BlocksOutputBuffer_Finish()

/*
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.

The first time a static builtin type is initialized, all the
normal PyType_Ready() stuff happens. The only difference from
normal is that there are three PyTypeObject fields holding
objects which are stored here (on PyInterpreterState) rather
than in the corresponding PyTypeObject fields. Those are:
tp_dict (cls.__dict__), tp_subclasses (cls.__subclasses__),
and tp_weaklist.
When a subinterpreter is initialized, each static builtin type
is still initialized, but only the interpreter-specific portion,
namely those three objects.
Those objects are stored in the PyInterpreterState.types.builtins
array, at the index corresponding to each specific static builtin
type. That index (a size_t value) is stored in the tp_subclasses
field. For static builtin types, we re-purposed the now-unused
tp_subclasses to avoid adding another field to PyTypeObject.
In all other cases tp_subclasses holds a dict like before.
(The field was previously defined as PyObject*, but is now void*
to reflect its dual use.)
The index for each static builtin type isn't statically assigned.
Instead it is calculated the first time a type is initialized
(by the main interpreter). The index matches the order in which
the type was initialized relative to the others. The actual
value comes from the current value of num_builtins_initialized,
as each type is initialized for the main interpreter.
num_builtins_initialized is incremented once for each static
builtin type. Once initialization is over for a subinterpreter,
the value will be the same as for all other interpreters. */

/* 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 https://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_);

}
Type *MyQueue::Get() {

/* 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:

The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a

/* 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
a debug build (Py_DEBUG macro), 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.

22-Feb-2006 MvL 1013 PEP 353 - long indices for sequence lengths
19-Aug-2002 GvR 1012 Changes to string object struct for

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)

// similar to C11 atomics.
//
// Operations are sequentially consistent unless they have a suffix indicating
// otherwise. If in doubt, prefer the sequentially consistent operations.
//
// The "_relaxed" suffix for load and store operations indicates the "relaxed"
// memory order. They don't provide synchronization, but (roughly speaking)
// guarantee somewhat sane behavior for races instead of undefined behavior.
// In practice, they correspond to "normal" hardware load and store
// instructions, so they are almost as inexpensive as plain loads and stores
// in C.
//
// Note that atomic read-modify-write operations like _Py_atomic_add_* return
// the previous value of the atomic variable, not the new value.
//
// See https://en.cppreference.com/w/c/atomic for more information on C11
// atomics.

PyLong_SHIFT. The majority of the code doesn't care about the precise
value of PyLong_SHIFT, but there are some notable exceptions:
- 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

/* 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)/(Py_TRASHCAN_HEADROOM-1) pieces,
with the call stack never exceeding a depth of Py_TRASHCAN_HEADROOM.
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().

// Python critical sections
//
// Conceptually, critical sections are a deadlock avoidance layer on top of
// per-object locks. These helpers, in combination with those locks, replace
// our usage of the global interpreter lock to provide thread-safety for
// otherwise thread-unsafe objects, such as dict.
//
// NOTE: These APIs are no-ops in non-free-threaded builds.
//
// Straightforward per-object locking could introduce deadlocks that were not
// present when running with the GIL. Threads may hold locks for multiple
// objects simultaneously because Python operations can nest. If threads were
// to acquire the same locks in different orders, they would deadlock.
//
// One way to avoid deadlocks is to allow threads to hold only the lock (or
// locks) for a single operation at a time (typically a single lock, but some
// operations involve two locks). When a thread begins a nested operation it
// could suspend the locks for any outer operation: before beginning the nested
// operation, the locks for the outer operation are released and when the
// nested operation completes, the locks for the outer operation are
// reacquired.
//
// To improve performance, this API uses a variation of the above scheme.
// Instead of immediately suspending locks any time a nested operation begins,
// locks are only suspended if the thread would block. This reduces the number
// of lock acquisitions and releases for nested operations, while still
// avoiding deadlocks.
//
// Additionally, the locks for any active operation are suspended around
// other potentially blocking operations, such as I/O. This is because the
// interaction between locks and blocking operations can lead to deadlocks in
// the same way as the interaction between multiple locks.
//
// Each thread's critical sections and their corresponding locks are tracked in
// a stack in `PyThreadState.critical_section`. When a thread calls
// `_PyThreadState_Detach()`, such as before a blocking I/O operation or when
// waiting to acquire a lock, the thread suspends all of its active critical
// sections, temporarily releasing the associated locks. When the thread calls
// `_PyThreadState_Attach()`, it resumes the top-most (i.e., most recent)
// critical section by reacquiring the associated lock or locks. See
// `_PyCriticalSection_Resume()`.
//
// NOTE: Only the top-most critical section is guaranteed to be active.
// Operations that need to lock two objects at once must use
// `Py_BEGIN_CRITICAL_SECTION2()`. You *CANNOT* use nested critical sections
// to lock more than one object at once, because the inner critical section
// may suspend the outer critical sections. This API does not provide a way
// to lock more than two objects at once (though it could be added later
// if actually needed).
//
// NOTE: Critical sections implicitly behave like reentrant locks because
// attempting to acquire the same lock will suspend any outer (earlier)
// critical sections. However, they are less efficient for this use case than
// purposefully designed reentrant locks.
//
// Example usage:
// Py_BEGIN_CRITICAL_SECTION(op);
// ...
// Py_END_CRITICAL_SECTION();
//
// To lock two objects at once:
// Py_BEGIN_CRITICAL_SECTION2(op1, op2);
// ...
// Py_END_CRITICAL_SECTION2();
