* [3.13] gh-121390: tracemalloc: Fix tracebacks memory leak (GH-121391) (#121392)Miss Islington (bot)2024-07-211-1/+1
| | | | | | | | | | | gh-121390: tracemalloc: Fix tracebacks memory leak (GH-121391) The tracemalloc_tracebacks hash table has traceback keys and NULL values, but its destructors do not reflect this -- key_destroy_func is NULL while value_destroy_func is raw_free. Swap these to free the traceback keys instead. (cherry picked from commit db39bc42f90c151b298f97b780e62703adbf1221) Co-authored-by: Josh Brobst <jbrobst@proton.me>

| | | | | | | | | | | | | | | | | (GH-121799) (#121821) We should maintain the invariant that a zero `ob_tid` implies the refcount fields are merged. * Move the assignment in `_Py_MergeZeroLocalRefcount` to immediately before the refcount merge. * Update `_PyTrash_thread_destroy_chain` to set `ob_ref_shared` to `_Py_REF_MERGED` when setting `ob_tid` to zero. Also check this invariant with assertions in the GC in debug builds. That uncovered a bug when running out of memory during GC.

| | | | | | | | | | | | | | (#121505) The `_PySeqLock_EndRead` function needs an acquire fence to ensure that the load of the sequence happens after any loads within the read side critical section. The missing fence can trigger bugs on macOS arm64.

It also fixes a failing assert (gh-120765), by making sure all subinterpreters are destroyed before the main interpreter. As part of that, we make sure Py_Finalize() always runs with the main interpreter active.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [3.13] gh-120161: Fix a Crash in the _datetime Module (gh-120518)Miss Islington (bot)2024-06-141-0/+1
| | | | | | | | | | | 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.
