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

| | | | | | | | | `_datetime` (gh-120424) 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()).

| | | | | | | | | | | | | | | | | (#120038) The `_PyThreadState_Bind()` function is called before the first `PyEval_AcquireThread()` so it's not synchronized with the stop the world GC. We had a race where `gc_visit_heaps()` might visit a thread's heap while it's being initialized. Use a simple atomic int to avoid visiting heaps for threads that are not yet fully initialized (i.e., before `tstate_mimalloc_bind()` is called). The race was reproducible by running: `python Lib/test/test_importlib/partial/pool_in_threads.py`.

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. (cherry picked from commit 47fb4327b5c405da6df066dcaa01b7c1aefab313)

* [3.13] gh-119213: Be More Careful About _PyArg_Parser.kwtuple Across ↵Miss Islington (bot)2024-05-221-0/+2
| | | | | | | | | | | | | Interpreters (gh-119331) (gh-119410) _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.
