* [3.13] gh-117398: Use Per-Interpreter State for the _datetime Static Types ↵Miss Islington (bot)2024-06-031-55/+142
| | | | | | | | | | | (gh-120009) We make use of the same mechanism that we use for the static builtin types. This required a few tweaks. This change is the final piece needed to make _datetime support multiple interpreters. I've updated the module slot accordingly.

* [3.13] gh-117398: Add datetime Module State (gh-120004)Miss Islington (bot)2024-06-031-162/+370
| | | | | | | | | | | | | | | | 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) (cherry picked from commit d82a7ba041321e7b58a5a9bbc394670be6ceeb7c, AKA gh-119810) Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>

* [3.13] gh-117657: Fix race involving immortalizing objects (GH-119927) (#120005)Sam Gross2024-06-031-15/+9
| | | | | | | | | | | 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. (cherry picked from commit 47fb4327b5c405da6df066dcaa01b7c1aefab313)

| | | | | | | | | | | (GH-103846) (GH-119830) Some of standard Tcl types were renamed, removed, or no longer registered in Tcl 8.7/9.0.

| | | | | | | The fix in gh-119561 introduced an assertion that doesn't hold true if any of the three new test extension modules are loaded more than once. This is fine normally but breaks if the new test_check_state_first() is run more than once, which happens for refleak checking and with the regrtest --forever flag. We fix that here by clearing each of the three modules after loading them. We also tweak a check in _modules_by_index_check().

* [3.13] gh-119213: Be More Careful About _PyArg_Parser.kwtuple Across ↵Miss Islington (bot)2024-05-222-1/+81
| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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).
