* [3.13] gh-76785: Expand How Interpreter Queues Handle Interpreter ↵Miss Islington (bot)2024-07-151-13/+128
| | | | | | | | | | | | | | | | | | | | | | | | Finalization (gh-121807) Any cross-interpreter mechanism for passing objects between interpreters must be very careful to respect isolation, even when the object is effectively immutable (e.g. int, str). Here this especially relates to when an interpreter sends one of its objects, and then is destroyed while the inter-interpreter machinery (e.g. queue) still holds a reference to the object. When I added interpreters.Queue, I dealt with that case (using an atexit hook) by silently removing all items from the queue that were added by the finalizing interpreter. Later, while working on concurrent.futures.InterpreterPoolExecutor (gh-116430), I noticed it was somewhat surprising when items were silently removed from the queue when the originating interpreter was destroyed. (See my comment on that PR.) It took me a little while to realize what was going on. I expect that users, which much less context than I have, would experience the same pain. My approach, here, to improving the situation is to give users three options: 1. return a singleton (interpreters.queues.UNBOUND) from Queue.get() in place of each removed item 2. raise an exception (interpreters.queues.ItemInterpreterDestroyed) from Queue.get() in place of each removed item 3. existing behavior: silently remove each item (i.e. Queue.get() skips each one) The default will now be (1), but users can still explicitly opt in any of them, including to the silent removal behavior. The behavior for each item may be set with the corresponding Queue.put() call. and a queue-wide default may be set when the queue is created. (This is the same as I did for "synconly".)

* [3.13] gh-117657: Fix race involving immortalizing objects (GH-119927) (#120005)Sam Gross2024-06-031-2/+2
| | | | | | | | | | | 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-118527: Intern code consts in free-threaded build (#118667)Sam Gross2024-05-071-0/+9
| | | | | | We already intern and immortalize most string constants. In the free-threaded build, other constants can be a source of reference count contention because they are shared by all threads running the same code objects.

* gh-118335: Configure Tier 2 interpreter at build time (#118339)Guido van Rossum2024-05-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | The code for Tier 2 is now only compiled when configured with `--enable-experimental-jit[=yes|interpreter]`. We drop support for `PYTHON_UOPS` and -`Xuops`, but you can disable the interpreter or JIT at runtime by setting `PYTHON_JIT=0`. You can also build it without enabling it by default using `--enable-experimental-jit=yes-off`; enable with `PYTHON_JIT=1`. On Windows, the `build.bat` script supports `--experimental-jit`, `--experimental-jit-off`, `--experimental-interpreter`. In the C code, `_Py_JIT` is defined as before when the JIT is enabled; the new variable `_Py_TIER2` is defined when the JIT *or* the interpreter is enabled. It is actually a bitmask: 1: JIT; 2: default-off; 4: interpreter.
* gh-117783: Immortalize objects that use deferred reference counting (#118112)Sam Gross2024-04-291-0/+19
| | | | | | | | | Deferred reference counting is not fully implemented yet. As a temporary measure, we immortalize objects that would use deferred reference counting to avoid multi-threaded scaling bottlenecks. This is only performed in the free-threaded build once the first non-main thread is started. Additionally, some tests, including refleak tests, suppress this behavior.

* gh-76785: Handle Legacy Interpreters Properly (gh-117490)Eric Snow2024-04-111-23/+56
| | | This is similar to the situation with threading._DummyThread. The methods (incl. __del__()) of interpreters.Interpreter objects must be careful with interpreters not created by interpreters.create(). The simplest thing to start with is to disable any method that modifies or runs in the interpreter. As part of this, the runtime keeps track of where an interpreter was created. We also handle interpreter "refcounts" properly.
* gh-117649: Raise ImportError for unsupported modules in free-threaded build ↵Sam Gross2024-04-111-0/+6
| | | | | | | | | | (#117651) The free-threaded build does not currently support the combination of single-phase init modules and non-isolated subinterpreters. Ensure that `check_multi_interp_extensions` is always `True` for subinterpreters in the free-threaded build so that importing these modules raises an `ImportError`.
* gh-76785: Add More Tests to test_interpreters.test_api (gh-117662)Eric Snow2024-04-111-3/+4
| | | In addition to the increase test coverage, this is a precursor to sorting out how we handle interpreters created directly via the C-API.
* gh-116303: Skip tests if C recursion limit is unavailable (GH-117368)Erlend E. Aasland2024-04-081-12/+8
| | | | | The test suite fetches the C recursion limit from the _testcapi extension module. Test extension modules can be disabled using the --disable-test-modules configure option.

| | | | | I had meant to switch everything to InterpreterError when I added it a while back. At the time I missed a few key spots. As part of this, I've added print-the-exception to _PyXI_InitTypes() and fixed an error case in `_PyStaticType_InitBuiltin().

* gh-76785: Add PyInterpreterConfig Helpers (gh-117170)Eric Snow2024-04-021-2/+13
| | | These helpers make it easier to customize and inspect the config used to initialize interpreters. This is especially valuable in our tests. I found inspiration from the PyConfig API for the PyInterpreterConfig dict conversion stuff. As part of this PR I've also added a bunch of tests.

* gh-116604: Fix test_gc on free-threaded build (#116662)Sam Gross2024-03-131-0/+10
| | | | | | | | | | The free-threaded GC only does full collections, so it uses a threshold that is a maximum of a fixed value (default 2000) and proportional to the number of live objects. If there were many live objects after the previous collection, then the threshold may be larger than 10,000 causing `test_indirect_calls_with_gc_disabled` to fail. This manually sets the threshold to `(1000, 0, 0)` for the test. The `0` disables the proportional scaling.
