Use _PyLong_IsNegative instead of _PyLong_Sign if appropriate. (GH-120493)
It is faster and more obvious.

gh-119344: Make critical section API public (#119353)
This makes the following macros public as part of the non-limited C-API for
locking a single object or two objects at once.

* `Py_BEGIN_CRITICAL_SECTION(op)` / `Py_END_CRITICAL_SECTION()`
* `Py_BEGIN_CRITICAL_SECTION2(a, b)` / `Py_END_CRITICAL_SECTION2()`

The supporting functions and structs used by the macros are also exposed for
cases where C macros are not available.

gh-113993: Allow interned strings to be mortal, and fix related issues (GH-120520)
* Add an InternalDocs file describing how interning should work and how to use it.

* Add internal functions to *explicitly* request what kind of interning is done:
  - `_PyUnicode_InternMortal`
  - `_PyUnicode_InternImmortal`
  - `_PyUnicode_InternStatic`

* Switch uses of `PyUnicode_InternInPlace` to those.

* Disallow using `_Py_SetImmortal` on strings directly.
  You should use `_PyUnicode_InternImmortal` instead:
  - Strings should be interned before immortalization, otherwise you're possibly
    interning a immortalizing copy.
  - `_Py_SetImmortal` doesn't handle the `SSTATE_INTERNED_MORTAL` to
    `SSTATE_INTERNED_IMMORTAL` update, and those flags can't be changed in
    backports, as they are now part of public API and version-specific ABI.

* Add private `_only_immortal` argument for `sys.getunicodeinternedsize`, used in refleak test machinery.

* Make sure the statically allocated string singletons are unique. This means these sets are now disjoint:
  - `_Py_ID`
  - `_Py_STR` (including the empty string)
  - one-character latin-1 singletons

  Now, when you intern a singleton, that exact singleton will be interned.

* Add a `_Py_LATIN1_CHR` macro, use it instead of `_Py_ID`/`_Py_STR` for one-character latin-1 singletons everywhere (including Clinic).

* Intern `_Py_STR` singletons at startup.

* For free-threaded builds, intern `_Py_LATIN1_CHR` singletons at startup.

* Beef up the tests. Cover internal details (marked with `@cpython_only`).

* Add lots of assertions

GH-73991: Add follow_symlinks argument to `pathlib.Path.copy()` (#120519)
Add support for not following symlinks in `pathlib.Path.copy()`.

On Windows we add the `COPY_FILE_COPY_SYMLINK` flag is following symlinks is disabled. If the source is symlink to a directory, this call will fail with `ERROR_ACCESS_DENIED`. In this case we add `COPY_FILE_DIRECTORY` to the flags and retry. This can fail on old Windowses, which we note in the docs.

No news as `copy()` was only just added.

gh-118789: Add `PyUnstable_Object_ClearWeakRefsNoCallbacks` (#118807)
This exposes `PyUnstable_Object_ClearWeakRefsNoCallbacks` as an unstable
C-API function to provide a thread-safe mechanism for clearing weakrefs
without executing callbacks.

Some C-API extensions need to clear weakrefs without calling callbacks,
such as after running finalizers like we do in subtype_dealloc.
Previously they could use `_PyWeakref_ClearRef` on each weakref, but
that's not thread-safe in the free-threaded build.

gh-120161: Fix a Crash in the _datetime Module (gh-120182)
In gh-120009 I used an atexit hook to finalize the _datetime module's static types at interpreter shutdown.  However, atexit hooks are executed very early in finalization, which is a problem in the few cases where a subclass of one of those static types is still alive until the final GC collection.  The static builtin types don't have this probably because they are finalized toward the end, after the final GC collection.  To avoid the problem for _datetime, I have applied a similar approach here.

Also, credit goes to @mgorny and @neonene for the new tests.

FYI, I would have liked to take a slightly cleaner approach with managed static types, but wanted to get a smaller fix in first for the sake of backporting.  I'll circle back to the cleaner approach with a future change on the main branch.

gh-71587: Drop local reference cache to `_strptime` module in `_datetime` (gh-120224)
The _strptime module object was cached in a static local variable (in the datetime.strptime() implementation).  That's a problem when it crosses isolation boundaries, such as reinitializing the runtme or between interpreters.  This change fixes the problem by dropping the static variable, instead always relying on the normal sys.modules cache (via PyImport_Import()).

gh-117398: Add datetime Module State (gh-119810)
I was able to make use of the existing datetime_state struct, but there was one tricky thing I had to sort out.  We mostly aren't converting to heap types, so we can't use things like PyType_GetModuleByDef() to look up the module state.  The solution I came up with is somewhat novel, but I consider it straightforward.  Also, it shouldn't have much impact on performance.

In summary, this main changes here are:

* I've added some macros to help hide how various objects relate to module state
* as a solution to the module state lookup problem, I've stored the last loaded module on the current interpreter's internal dict (actually a weakref)
* if the static type method is used after the module has been deleted, it is reloaded
* to avoid extra work when loading the module, we directly copy the objects (new refs only) from the old module state into the new state if the old module hasn't been deleted yet
* during module init we set various objects on the static types' __dict__s; to simplify things, we only do that the first time; once those static types have a separate __dict__ per interpreter, we'll do it every time
* we now clear the module state when the module is destroyed (before, we were leaking everything in _datetime_global_state)

gh-117657: Fix race involving immortalizing objects (#119927)
The free-threaded build currently immortalizes objects that use deferred
reference counting (see gh-117783). This typically happens once the
first non-main thread is created, but the behavior can be suppressed for
tests, in subinterpreters, or during a compile() call.

This fixes a race condition involving the tracking of whether the
behavior is suppressed.

gh-119461: Fix ThreadedVSOCKSocketStreamTest (#119465)
Add socket.VMADDR_CID_LOCAL constant.

Fix ThreadedVSOCKSocketStreamTest: if get_cid() returns the host
address or the "any" address, use the local communication address
(loopback): VMADDR_CID_LOCAL.

On Linux 6.9, apparently, the /dev/vsock device is now available but
get_cid() returns VMADDR_CID_ANY (-1).

gh-117142: Slightly hacky fix for memory leak of StgInfo (GH-119424)
Add a funciton that inlines PyObject_GetTypeData and skips
type-checking, so it doesn't need access to the CType_Type object.
This will break if the memory layout changes, but should
be an acceptable solution to enable ctypes in subinterpreters in
Python 3.13.

Mark _ctypes as safe for multiple interpreters

Remove almost all unpaired backticks in docstrings (#119231)
As reported in #117847 and #115366, an unpaired backtick in a docstring
tends to confuse e.g. Sphinx running on subclasses of standard library
objects, and the typographic style of using a backtick as an opening
quote is no longer in favor. Convert almost all uses of the form

    The variable `foo' should do xyz

to

    The variable 'foo' should do xyz

and also fix up miscellaneous other unpaired backticks (extraneous /
missing characters).

No functional change is intended here other than in human-readable
docstrings.

gh-119213: Be More Careful About _PyArg_Parser.kwtuple Across Interpreters (gh-119331)
_PyArg_Parser holds static global data generated for modules by Argument Clinic.  The _PyArg_Parser.kwtuple field is a tuple object, even though it's stored within a static global.  In some cases the tuple is statically allocated and thus it's okay that it gets shared by multiple interpreters.  However, in other cases the tuple is set lazily, allocated from the heap using the active interprepreter at the point the tuple is needed.

This is a problem once that interpreter is destroyed since _PyArg_Parser.kwtuple becomes at dangling pointer, leading to crashes.  It isn't a problem if the tuple is allocated under the main interpreter, since its lifetime is bound to the lifetime of the runtime.  The solution here is to temporarily switch to the main interpreter.  The alternative would be to always statically allocate the tuple.

This change also fixes a bug where only the most recent parser was added to the global linked list.

gh-116322: Add Py_mod_gil module slot (#116882)
This PR adds the ability to enable the GIL if it was disabled at
interpreter startup, and modifies the multi-phase module initialization
path to enable the GIL when loading a module, unless that module's spec
includes a slot indicating it can run safely without the GIL.

PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went
with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148.

A warning will be issued up to once per interpreter for the first
GIL-using module that is loaded. If `-v` is given, a shorter message
will be printed to stderr every time a GIL-using module is loaded
(including the first one that issues a warning).

gh-118335: Configure Tier 2 interpreter at build time (#118339)
The code for Tier 2 is now only compiled when configured
with `--enable-experimental-jit[=yes|interpreter]`.

We drop support for `PYTHON_UOPS` and -`Xuops`,
but you can disable the interpreter or JIT
at runtime by setting `PYTHON_JIT=0`.
You can also build it without enabling it by default
using `--enable-experimental-jit=yes-off`;
enable with `PYTHON_JIT=1`.

On Windows, the `build.bat` script supports
`--experimental-jit`, `--experimental-jit-off`,
`--experimental-interpreter`.

In the C code, `_Py_JIT` is defined as before
when the JIT is enabled; the new variable
`_Py_TIER2` is defined when the JIT *or* the
interpreter is enabled. It is actually a bitmask:
1: JIT; 2: default-off; 4: interpreter.

gh-76785: Handle Legacy Interpreters Properly (gh-117490)
This is similar to the situation with threading._DummyThread.  The methods (incl. __del__()) of interpreters.Interpreter objects must be careful with interpreters not created by interpreters.create().  The simplest thing to start with is to disable any method that modifies or runs in the interpreter.  As part of this, the runtime keeps track of where an interpreter was created.  We also handle interpreter "refcounts" properly.

gh-117233: Detect support for several hashes at hashlib build time (GH-117234)
Detect libcrypto BLAKE2, Shake, SHA3, and Truncated-SHA512 support at hashlib build time

## BLAKE2

While OpenSSL supports both "b" and "s" variants of the BLAKE2 hash
function, other cryptographic libraries may lack support for one or both
of the variants. This commit modifies `hashlib`'s C code to detect
whether or not the linked libcrypto supports each BLAKE2 variant, and
elides references to each variant's NID accordingly. In cases where the
underlying libcrypto doesn't fully support BLAKE2, CPython's
`./configure` script can be given the following flag to use CPython's
interned BLAKE2 implementation: `--with-builtin-hashlib-hashes=blake2`.

## SHA3, Shake, & truncated SHA512.

Detect BLAKE2, SHA3, Shake, & truncated SHA512 support in the
OpenSSL-ish libcrypto library at build time.  This helps allow hashlib's
`_hashopenssl` to be used with libraries that do not to support every
algorithm that upstream OpenSSL does.  Such as AWS-LC & BoringSSL.

gh-111926: Make weakrefs thread-safe in free-threaded builds (#117168)
Most mutable data is protected by a striped lock that is keyed on the
referenced object's address. The weakref's hash is protected using the
weakref's per-object lock.
 
Note that this only affects free-threaded builds. Apart from some minor
refactoring, the added code is all either gated by `ifdef`s or is a no-op
(e.g. `Py_BEGIN_CRITICAL_SECTION`).

(supposed to be) identical.

The behavior of the Tier 2 counters is changed:
- There are no longer dynamic thresholds (we never varied these).
- All counters now use the same exponential backoff.
- The counter for ``JUMP_BACKWARD`` starts counting down from 16.
- The ``temperature`` in side exits starts counting down from 64.

gh-115627: Fix PySSL_SetError handling SSL_ERROR_SYSCALL (GH-115628)
Python 3.10 changed from using SSL_write() and SSL_read() to SSL_write_ex() and
SSL_read_ex(), but did not update handling of the return value.

Change error handling so that the return value is not examined.
OSError (not EOF) is now returned when retval is 0.

According to *recent* man pages of all functions for which we call
PySSL_SetError, (in OpenSSL 3.0 and 1.1.1), their return value should
be used to determine whether an error happened (i.e. if PySSL_SetError
should be called), but not what kind of error happened (so,
PySSL_SetError shouldn't need retval). To get the error,
we need to use SSL_get_error.

gh-105716: Fix _PyInterpreterState_IsRunningMain() For Embedders (gh-117140)
When I added _PyInterpreterState_IsRunningMain() and friends last year, I tried to accommodate applications that embed Python but don't call _PyInterpreterState_SetRunningMain() (not that they're expected to).  That mostly worked fine until my recent changes in gh-117049, where the subtleties with the fallback code led to failures; the change ended up breaking test_tools.test_freeze, which exercises a basic embedding situation.

The simplest fix is to drop the fallback code I originally added to _PyInterpreterState_IsRunningMain() (and later to _PyThreadState_IsRunningMain()).  I've kept the fallback in the _xxsubinterpreters module though.  I've also updated Py_FrozenMain() to call _PyInterpreterState_SetRunningMain().

is in a consistent state before forking.

gh-114314: ctypes: remove stgdict and switch to heap types (GH-116458)
Before this change, ctypes classes used a custom dict subclass, `StgDict`,
as their `tp_dict`. This acts like a regular dict but also includes extra information
about the type.

This replaces stgdict by `StgInfo`, a C struct on the type, accessed by
`PyObject_GetTypeData()` (PEP-697).
All usage of `StgDict` (mainly variables named `stgdict`, `dict`, `edict` etc.) is
converted to `StgInfo` (named `stginfo`, `info`, `einfo`, etc.).
Where the dict is actually used for class attributes (as a regular PyDict), it's now
called `attrdict`.

This change -- not overriding `tp_dict` -- is made to make me comfortable with
the next part of this PR: moving the initialization logic from `tp_new` to `tp_init`.

The `StgInfo` is set up in `__init__` of each class, with a guard that prevents
calling `__init__` more than once. Note that abstract classes (like `Array` or
`Structure`) are created using `PyType_FromMetaclass` and do not have
`__init__` called.
Previously, this was done in `__new__`, which also wasn't called for abstract
classes.
Since `__init__` can be called from Python code or skipped, there is a tested
guard to ensure `StgInfo` is initialized exactly once before it's used.

earnest.

This changes the checks to use `_PyInterpreterState_GetFinalizing(interp)`,
which is set immediately before terminating non-daemon threads.
