* gh-104050: Run mypy on `clinic.py` in CI (#104421)Alex Waygood2023-05-154-24/+55
| | | | | | | | | | * Add basic mypy workflow to CI * Make the type check pass --------- Co-authored-by: Erlend E. Aasland <erlend.aasland@protonmail.com> Co-authored-by: Nikita Sobolev <mail@sobolevn.me> Co-authored-by: Hugo van Kemenade <hugovk@users.noreply.github.com>
* GH-103082: Filter LINE events in VM, to simplify tool implementation. ↵Mark Shannon2023-05-121-1/+1
| | | | | | | | (GH-104387) When monitoring LINE events, instrument all instructions that can have a predecessor on a different line. Then check that the a new line has been hit in the instrumentation code. This brings the behavior closer to that of 3.11, simplifying implementation and porting of tools.
* gh-104389: Add 'unused' keyword to Argument Clinic C converters (#104390)Erlend E. Aasland2023-05-121-1/+19

* gh-99108: Replace SHA3 implementation HACL* version (#103597)Jonathan Protzenko2023-05-081-7/+1
| | | | | | | | | | | Replaces our built-in SHA3 implementation with a verified one from the HACL* project. This implementation is used when OpenSSL does not provide SHA3 or is not present. 3.11 shiped with a very slow tiny sha3 implementation to get off of the <=3.10 reference implementation that wound up having serious bugs. This brings us back to a reasonably performing built-in implementation consistent with what we've just replaced our other guaranteed available standard hash algorithms with: code from the HACL* project. --------- Co-authored-by: Gregory P.

* gh-101659: Isolate "obmalloc" State to Each Interpreter (gh-101660)Eric Snow2023-04-241-0/+1
| | | | | | | | | | | | | | This is strictly about moving the "obmalloc" runtime state from `_PyRuntimeState` to `PyInterpreterState`. Doing so improves isolation between interpreters, specifically most of the memory (incl. objects) allocated for each interpreter's use. This is important for a per-interpreter GIL, but such isolation is valuable even without it. FWIW, a per-interpreter obmalloc is the proverbial canary-in-the-coalmine when it comes to the isolation of objects between interpreters. Any object that leaks (unintentionally) to another interpreter is highly likely to cause a crash (on debug builds at least). That's a useful thing to know, relative to interpreter isolation.

* gh-84436: Implement Immortal Objects (gh-19474)Eddie Elizondo2023-04-221-1/+1
| | | | | | | | | This is the implementation of PEP683 Motivation: The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime. Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.

| | | | | | | | | | * Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts. * Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints. * Add functions to hide some internals of long object, and for setting sign and digit count. * Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().

| | | | | | | The essentially eliminates the global variable, with the associated benefits. This is also a precursor to isolating this bit of state to PyInterpreterState.
