* [3.13] gh-128679: Fix tracemalloc.stop() race conditions (#128897)Victor Stinner2025-01-181-1/+1
| | | | | | | | | | | | | tracemalloc_alloc(), tracemalloc_realloc(), PyTraceMalloc_Track(), PyTraceMalloc_Untrack() and _PyTraceMalloc_TraceRef() now check tracemalloc_config.tracing after calling TABLES_LOCK(). _PyTraceMalloc_Stop() now protects more code with TABLES_LOCK(), especially setting tracemalloc_config.tracing to 1. Add a test using PyTraceMalloc_Track() to test tracemalloc.stop() race condition. Call _PyTraceMalloc_Init() at Python startup.

* [3.13] gh-127582: Make object resurrection thread-safe for free threading. ↵Sam Gross2024-12-051-0/+44
| | | | | | | | | | | | | | | (GH-127612) (GH-127659) Objects may be temporarily "resurrected" in destructors when calling finalizers or watcher callbacks. We previously undid the resurrection by decrementing the reference count using `Py_SET_REFCNT`. This was not thread-safe because other threads might be accessing the object (modifying its reference count) if it was exposed by the finalizer, watcher callback, or temporarily accessed by a racy dictionary or list access. This adds internal-only thread-safe functions for temporary object resurrection during destructors. (cherry picked from commit f4f530804b9d8f089eba0f157ec2144c03b13651)

| | | | | | | | | | | (#122984) gh-122907: Fix Builds Without HAVE_DYNAMIC_LOADING Set (gh-122952) As of 529a160 (gh-118204), building with HAVE_DYNAMIC_LOADING stopped working. This is a minimal fix just to get builds working again. There are actually a number of long-standing deficiencies with HAVE_DYNAMIC_LOADING builds that need to be resolved separately.

* [3.13] gh-126914: Store the Preallocated Thread State's Pointer in a ↵Eric Snow2024-12-021-0/+2
| | | | | | | PyInterpreterState Field (gh-127114) This approach eliminates the originally reported race. It also gets rid of the deadlock reported in gh-96071, so we can remove the workaround added then. This is mostly a cherry-pick of 1c0a104 (AKA gh-126989). The difference is we add PyInterpreterState.threads_preallocated at the end of PyInterpreterState, instead of adding PyInterpreterState.threads.preallocated. That avoids ABI disruption.

| | | | | | | | | | | | | | (GH-125882) (GH-125921) This fixes a crash when `gc.get_objects()` or `gc.get_referrers()` is called during a GC in the free threading build. Switch to `_PyObjectStack` to avoid corrupting the `struct worklist` linked list maintained by the GC. Also, don't return objects that are frozen (`gc.freeze()`) or in the process of being collected to more closely match the behavior of the default build.

| | | | | | | | | | | | | (GH-125574) (GH-125595) On Arm v5 it is not possible to get the thread ID via c13 register hence the illegal instruction. The c13 register started to provide thread ID since Arm v6K architecture variant. Other variants of Arm v6 (T2, Z and base) don’t provide the thread ID via c13. For the sake of simplicity we group v5 and v6 together and consider that instructions for Arm v7 only.

* [3.13] gh-117482: Simplify the Fix For Builtin Types Slot Wrappers (gh-121932)Eric Snow2024-07-241-1/+0
| | | | | | | | | | | | | | | In gh-121602, I applied a fix to a builtin types initialization bug. That fix made sense in the context of some broader future changes, but introduced a little bit of extra complexity. For earlier versions those future changes are not relevant; we can avoid the extra complexity. Thus we can revert that earlier change and replace it with this one, which is more focused and conceptually simpler. This is essentially the implementation of an idea that @markshannon pointed out to me. Note that this change would be much smaller if we didn't have to deal with repr compatibility for builtin types that explicitly inherit tp slots (see expect_manually_inherited()). The alternative is to stop *explicitly* inheriting tp slots in static PyTypeObject values, which is churn that we can do separately.

| | | | | | | When builtin static types are initialized for a subinterpreter, various "tp" slots have already been inherited (for the main interpreter).

This change fixes that by preserving the original data from the static type struct and checking that.

* [3.13] gh-113993: Allow interned strings to be mortal, and fix related ↵Petr Viktorin2024-06-245-818/+1545
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | issues (GH-120520) (GH-120945) * 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 Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>

* [3.13] gh-119344: Make critical section API public (GH-119353) (#120856)Sam Gross2024-06-211-150/+68
| | | | | | | | | | | 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.
