* gh-125900: Clean-up logic around immortalization in free-threading (#125901)Sam Gross2024-10-24
| | | | | | | | | * Remove `@suppress_immortalization` decorator * Make suppression flag per-thread instead of per-interpreter * Suppress immortalization in `eval()` to avoid refleaks in three tests (test_datetime.test_roundtrip, test_logging.test_config8_ok, and test_random.test_after_fork). * frozenset() is constant, but not a singleton. When run multiple times, the test could fail due to constant interning.

* gh-120065: Increase `collect_in_thread` period to 5 ms. (#120068)Sam Gross2024-06-05
| | | | | This matches the default GIL switch interval. It greatly speeds up the free-threaded build: previously, it spent nearly all its time in `gc.collect()`.
* gh-118335: Configure Tier 2 interpreter at build time (#118339)Guido van Rossum2024-04-30
| | | | | | | | | | | | | | | | | | | | | | 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 Gross2024-04-29
| | | | | | | | | 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-118331: Don't raise an error if tuple allocation fails when clearing ↵mpage2024-04-29
| | | | | | | | | | weakrefs (#118338) It's not safe to raise an exception in `PyObject_ClearWeakRefs()` if one is not already set, since it may be called by `_Py_Dealloc()`, which requires that the active exception does not change. Additionally, make sure we clear the weakrefs even when tuple allocation fails.
* gh-117657: Add TSAN suppressions for the free-threaded build (#117736)mpage2024-04-15
| | | | | Additionally, reduce the iterations for a few weakref tests that would otherwise take a prohibitively long amount of time (> 1 hour) when TSAN is enabled and the GIL is disabled.
* gh-111926: Make weakrefs thread-safe in free-threaded builds (#117168)mpage2024-04-08
| | | | | | | | | Most mutable data is protected by a striped lock that is keyed on the referenced object's address. The weakref's hash is protected using the weakref's per-object lock. Note that this only affects free-threaded builds. Apart from some minor refactoring, the added code is all either gated by `ifdef`s or is a no-op (e.g. `Py_BEGIN_CRITICAL_SECTION`).

* gh-117281: Change weakref repr() to fully qualified name (#117285)Victor Stinner2024-04-03
| | | | | | | | Use the fully qualified type name in repr() of weakref.ref and weakref.proxy types. Fix a crash in proxy_repr() when the reference is dead. Add also test_ref_repr() and test_proxy_repr().
* gh-108416: Mark slow test methods with @requires_resource('cpu') (GH-108421)Serhiy Storchaka2023-09-02
| | | | Only mark tests which spend significant system or user time, by itself or in subprocesses.

* bpo-38395: Fix ownership in weakref.proxy methods (GH-16632)Pablo Galindo2019-10-08
| | | | | | | | | | | | | The implementation of weakref.proxy's methods call back into the Python API using a borrowed references of the weakly referenced object (acquired via PyWeakref_GET_OBJECT). This API call may delete the last reference to the object (either directly or via GC), leaving a dangling pointer, which can be subsequently dereferenced. To fix this, claim a temporary ownership of the referenced object when calling the appropriate method. Some functions because at the moment they do not need to access the borrowed referent, but to protect against future changes to these functions, ownership need to be fixed in all potentially affected methods.
* bpo-38006: Avoid closure in weakref.WeakValueDictionary (GH-15641)Victor Stinner2019-09-09
| | | | | weakref.WeakValueDictionary defines a local remove() function used as callback for weak references. This function was created with a closure. Modify the implementation to avoid the closure.
* bpo-37685: Fixed __eq__, __lt__ etc implementations in some classes. (GH-14952)Serhiy Storchaka2019-08-08

| | | | | | | | | | | | | | | | | | | | | | Deprecated passing the following arguments as keyword arguments: - "func" in functools.partialmethod(), weakref.finalize(), profile.Profile.runcall(), cProfile.Profile.runcall(), bdb.Bdb.runcall(), trace.Trace.runfunc() and curses.wrapper(). - "function" in unittest.addModuleCleanup() and unittest.TestCase.addCleanup(). - "fn" in the submit() method of concurrent.futures.ThreadPoolExecutor and concurrent.futures.ProcessPoolExecutor. - "callback" in contextlib.ExitStack.callback(), contextlib.AsyncExitStack.callback() and contextlib.AsyncExitStack.push_async_callback(). - "c" and "typeid" in the create() method of multiprocessing.managers.Server and multiprocessing.managers.SharedMemoryServer. - "obj" in weakref.finalize(). Also allowed to pass arbitrary keyword arguments (even "self" and "func") if the above arguments are passed as positional argument.
