* GH-113171: Fix "private" (non-global) IP address ranges (GH-113179)Jakub Stasiak2024-03-225-7/+82
| | | | | | | | | | | | | | | | | | | | | * GH-113171: Fix "private" (really non-global) IP address ranges The _private_networks variables, used by various is_private implementations, were missing some ranges and at the same time had overly strict ranges (where there are more specific ranges considered globally reachable by the IANA registries). This patch updates the ranges with what was missing or otherwise incorrect. I left 100.64.0.0/10 alone, for now, as it's been made special in [1] and I'm not sure if we want to undo that as I don't quite understand the motivation behind it. The _address_exclude_many() call returns 8 networks for IPv4, 121 networks for IPv6. [1] https://github.com/python/cpython/issues/61602

* GH-116939: Rewrite binarysort() (#116940)Tim Peters2024-03-222-66/+141
| | | | | | | | | | | | | | | | | | | | | | | | Rewrote binarysort() for clarity. Also changed the signature to be more coherent (it was mixing sortslice with raw pointers). No change in method or functionality. However, I left some experiments in, disabled for now via `#if` tricks. Since this code was first written, some kinds of comparisons have gotten enormously faster (like for lists of floats), which changes the tradeoffs. For example, plain insertion sort's simpler innermost loop and highly predictable branches leave it very competitive (even beating, by a bit) binary insertion when comparisons are very cheap, despite that it can do many more compares. And it wins big on runs that are already sorted (moving the next one in takes only 1 compare then). So I left code for a plain insertion sort, to make future experimenting easier. Also made the maximum value of minrun a `#define` (``MAX_MINRUN`) to make experimenting with that easier too. And another bit of `#if``-disabled code rewrites binary insertion's innermost loop to remove its unpredictable branch. Surprisingly, this doesn't really seem to help overall. I'm unclear on why not. It certainly adds more instructions, but they're very simple, and it's hard to be believe they cost as much as a branch miss.
* gh-108716:: Remove _PyStaticCode_Init/Fini (#117141)Guido van Rossum2024-03-221-46/+0
| | | More deepfreeze cleanup.
* gh-105716: Fix _PyInterpreterState_IsRunningMain() For Embedders (gh-117140)Eric Snow2024-03-223-22/+39
| | | | | 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().

* gh-117045: Add code object to function version cache (#117028)Guido van Rossum2024-03-218-96/+209
| | | | | | | | | | | | | | | | | | | | | | | | | | Changes to the function version cache: - In addition to the function object, also store the code object, and allow the latter to be retrieved even if the function has been evicted. - Stop assigning new function versions after a critical attribute (e.g. `__code__`) has been modified; the version is permanently reset to zero in this case. - Changes to `__annotations__` are no longer considered critical. (This fixes gh-109998.) Changes to the Tier 2 optimization machinery: - If we cannot map a function version to a function, but it is still mapped to a code object, we continue projecting the trace. The operand of the `_PUSH_FRAME` and `_POP_FRAME` opcodes can be either NULL, a function object, or a code object with the lowest bit set. This allows us to trace through code that calls an ephemeral function, i.e., a function that may not be alive when we are constructing the executor, e.g. a generator expression or certain nested functions. We will lose globals removal inside such functions, but we can still do other peephole operations (and even possibly [call inlining](https://github.com/python/cpython/pull/116290), if we decide to do it), which only need the code object. As before, if we cannot retrieve the code object from the cache, we stop projecting.
* gh-116333: Relax error string text expectations in SSL-related tests (GH-116334)Will Childs-Klein2024-03-214-38/+96
| | | | | | | | | | | | | | | | | | | * Relax error string text expectations in SSL-related tests As suggested [here][1], this change relaxes the OpenSSL error string text expectations in a number of tests. This was specifically done in support of more easily building CPython [AWS-LC][2], but because AWS-LC is a fork of [BoringSSL][3], it should increase compatibility with that library as well. In addition to the error string relaxations, we also add some guards around the `tls-unique` channel binding being used with TLSv1.3, as that feature (described in [RFC 6929][4]) is [not defined][5] for TLSv1.3.

* gh-116522: Refactor `_PyThreadState_DeleteExcept` (#117131)Sam Gross2024-03-215-23/+41
| | | | | | | | | | | Split `_PyThreadState_DeleteExcept` into two functions: - `_PyThreadState_RemoveExcept` removes all thread states other than one passed as an argument. It returns the removed thread states as a linked list. - `_PyThreadState_DeleteList` deletes those dead thread states. It may call destructors, so we want to "start the world" before calling `_PyThreadState_DeleteList` to avoid potential deadlocks.

* gh-76785: Drop PyInterpreterID_Type (gh-117101)Eric Snow2024-03-2118-449/+363
| | | I added it quite a while ago as a strategy for managing interpreter lifetimes relative to the PEP 554 (now 734) implementation. Relatively recently I refactored that implementation to no longer rely on InterpreterID objects. Thus now I'm removing it.

* gh-115754: Add Py_GetConstant() function (#116883)Victor Stinner2024-03-2122-6/+312
| | | | | | | | | | | | Add Py_GetConstant() and Py_GetConstantBorrowed() functions. In the limited C API version 3.13, getting Py_None, Py_False, Py_True, Py_Ellipsis and Py_NotImplemented singletons is now implemented as function calls at the stable ABI level to hide implementation details. Getting these constants still return borrowed references. Add _testlimitedcapi/object.c and test_capi/test_object.py to test Py_GetConstant() and Py_GetConstantBorrowed() functions.

* gh-76785: Clean Up Interpreter ID Conversions (gh-117048)Eric Snow2024-03-218-178/+143

* gh-116522: Stop the world before fork() and during shutdown (#116607)Sam Gross2024-03-213-7/+30
| | | | | | | | | | | This changes the free-threaded build to perform a stop-the-world pause before deleting other thread states when forking and during shutdown. This fixes some crashes when using multiprocessing and during shutdown when running with `PYTHON_GIL=0`. This also changes `PyOS_BeforeFork` to acquire the runtime lock (i.e., `HEAD_LOCK(&_PyRuntime)`) before forking to ensure that data protected by the runtime lock (and not just the GIL or stop-the-world) is in a consistent state before forking.

* gh-114314: ctypes: remove stgdict and switch to heap types (GH-116458)Petr Viktorin2024-03-2015-1411/+1496
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
