Sleef functions can't be inlined

39

In PyTorch, we'd like to use Sleef's vectorized implementation of elementary functions as building blocks. For example, we'd like to implement a vectorized [`sigmoid()`](https://en.wikipedia.org/wiki/Sigmoid_function) function using `exp`. However, calling into...

btrifact() may dereference nullptr

Here is the generated code: ```c++ std::tuple CPUFloatType::btrifact(const Tensor & info, bool pivot, const Tensor & self) { auto result_ = new CPUFloatTensor(context); auto result = Tensor(result_,false); auto pivots_ =...

Fixes #50

The following crashes in a debug build of Python: ```python import gc import pycld2 gc.collect() ``` ``` Modules/gcmodule.c:114: gc_decref: Assertion "gc_get_refs(g) > 0" failed: refcount is too small Enable tracemalloc...

`uv` should exclude `abi3` wheels in free-threaded Python 3.13+

5

Starting with the version 3.13 alpha releases, CPython can optionally be configured to run without the global interpreter lock. This build configuration ("free-threaded") is not compatible with `abi3` wheels. Additionally,...

# Feature or enhancement The steering council has [accepted](https://discuss.python.org/t/pep-703-making-the-global-interpreter-lock-optional-in-cpython-acceptance/37075) [PEP 703](https://peps.python.org/pep-0703/). This is intended as a top-level issue to keep track of integration status. The "up for grabs" list contains...

Make the Python test suite pass with the GIL disabled

# Feature or enhancement This issue is to track the remaining bugs that prevent the Python test suite from passing with the GIL disabled, as well as the PRs under...

Use stop-the-world to make fork and interpreter shutdown thread-safe

3

# Feature or enhancement In the free-threaded build, we should use a stop-the-world call to make `fork()` [^1] and shutdown (i.e, [`Py_FinalizeEx`](https://github.com/python/cpython/blob/c951e25c24910064a4c8b7959e2f0f7c0d4d0a63/Python/pylifecycle.c#L1866)) thread-safe. The two operations are similar in that...

[`rr`](https://github.com/rr-debugger/rr) is a record & replay debugging tool. I've found it particularly helpful for debugging multiprocessing issues, free-threading bugs, and non-deterministic crashes. @ericsnowcurrently suggested adding a devguide entry for how...

Don't build with limited API for 3.13 free-threaded build
